Description:

The invention to be hereinafter described relates to sanitary toilets and equipment therefor.

The present general practice, of course, involves the use of a water closet, dry closet or chemical closet to receive the waste and the use of paper to cleanse the body vents through which the waste is discharged. Under the most favorable conditions cleansing is imperfect and there is danger of injury resulting from irritation, abrasion, etc., of the parts by the paper. Frequently, the skin and flesh bordering or within the vent will be irritated or raw and sore to the touch and very painful to the use of paper. And, of course, in that condition, it is far more susceptible to injury, infection and disease. The main objects of the present invention are to eliminate the use of paper and to substantially abolish all dry wiping action. Instead, the parts are washed with currents of water directed particularly to them .and the body immediately thereabout. The flow of water is closely confined to a very limited area at and around the vent.

Preferably, the water is maintained approximately at body temperature in any well known manner, which need not be illustrated or described in this application. The parts washed are then wiped to remove drip and free water. And this is followed by an air current directed thereon to loosen and fluff any matted condition of the.hair, possibly caused by the wiper. The washing water, with waste, flows continually from the washed parts into the waste bowl, so that fresh clean water, only, contacts the body.

In order to more clearly disclose the construction, operation and use of the invention, reference should be had to the accompanying drawings forming part of the present application.

Throughout the several figures of the drawings, like reference characters designate the same parts in the different views: In the drawings: Fig. 1 is a top plan view of the invention, with seat and cover positions dotted in, only; Fig. 2 is a vertical longitudinal cross section on line 2-2 of Fig. 1, looking in the direction of the arrows, with seat and cover in normal positions, the trip 39' and switch 40 being omitted for clearness; Fig. 3 is a lateral vertical cross section on line 3-3 of Fig. 1, showing bowl 37 enlarged, looking in the direction of the arrows; Fig. 4 is an enlarged side elevation of the mechanism for reciprocating the anus washer, looking in the direction corresponding to Fig. 2, and with the parts in the positions of that figure; Fig. 5 is a top plan view of Fig. 4, enlarged, showing the pivoted plate to operate the switch to control the flow to the anus washer and.the pivoted forked switch to stop the motor; Fig. 6 is-a longitudinal cross section on line 6-6 of Fig. 1, enlarged, looking in the direction of the arrows; Fig. 7 is a fragmentary detail, enlarged, of the switch device for the telescopic bowl tube, showing the pivoted trip; Fig. 8 is a diagrammatic view of the float operated switch controlling the feed water supply to the wall tank, enlarged; and, Fig. 9 is a top plan view of bowl 86, removed, with its tube end and support.

In Figs. 1 and 2, air and water pipes which are carried by telescoping tubes 34 and 80, within the base, are indicated by single lines, where they appear in groups, for clearness. In those figures, too, many parts, especially bowls 37 and 86, are disproportionately large, for clearness.

The electric circuits for actuating the various solenoid valves'and the several motors are all very well known and understood by all skilled in the art to which the invention relates. It is, therefore, thought not only unnecessary but inadvisable to illustrate any of them either diagrammatically or otherwise. Accordingly, only the valves .or. other devices actuated by the respective circuits and the push buttons or switches have been shown.

In the preferred construction and arrangement of my invention, I provide a box-like base I of generally oblong outline or plan. This base has the full length side walls 2 and the exterior end walls 3 and 4 all of which extend the full height of the base, and bottom 7. About mid-way of the length of the base a forwardly and downwardly inclined partition wall 5 provides the rear of .a closet bowl, the forward part being formed by a similar wall 6 inclined toward wall 5 and spaced from the front. Walls 2, 5 and 6, together with bottom 7 constitute the waste or closet bowl, provided with the usual seat 8. The body of the side walls 2 and front wall 3 are hollow and in the form, approximately, of inverted V's, forming a flush.tank continuous around those three sides, from which flushing water may be released through an opening 6', as will later appear. This inverted V is clearly shown at the right hand end of Fig. 2, at the front end of the bowl, walls 3 and 6 merging at the top. The inner and outer faces of the side walls form similar V's in the same way and may extend the whole length of each wall or whatever portion of that full length may be desired. This gives a continuous tank across the front and along the two sides. There are, of course, small air vents for escape of air as the flush tank fills. In this connection, it will be noted that the rear bowl wall 5 does not extend down to the bottom. It stops considerably short of the bottom, leaving an opening of considerable vertical height extending the full width of the base from one side wall to the other. And here, it should be pointed out, that the bottom 7 is inclined, the low end being at the rear a short distance beyond the lower end or edge of rear bowl wall 5. This passage between 5 and 7 communicates with the forward end of trap 9 which delivers to the upper end of the sewer pipe 10. As in other water closets, after each flushing operation, which may be accomplished in the usual manner, water will remain in the bottom of the bowl up to the water level line indicated or, approximately, to the high point or top of the first bend of the trap. Below this level, so that it will at all times be immersed in water, is the endless or belt conveyor II which may be of any one of a wide variety of constructions: The usual end rolls or shafts for it may be suitably journaled in the side walls 2. The rear end of II extends considerably beyond rear bowl wall 5 and into the forward part of chamber 12 communicating with the upper end of trap 9. It is so driven, as will later appear, that its upper run, moves from front to rear of the base, delivering its load over the rear end and through the trap 9 into the sewer pipe. At the rear end, a flexible rubber scraper blade I I' is removably mounted in position to scrape from the conveyor any adhering matter as the conveyor makes its turn from the upper to the lower run. The flush is controlled in usual manner by the push button 56 marked "flush," in the panel 23. Movement of button 56 operates the circuit of electrically actuated solenoid valve 103 controlling the opening 6' through which the flush water is delivered from the tank into the toilet.

Water to supply the flush tank between side and end walls of the base may be brought in through the same supply as for other uses in the invention and may be controlled by the solenoid valve 104 actuated by a float 105 mounted in the tank and having an arm which, as the water level reaches a high point, swings a rocker switch to break a circuit to close valve 104 and as the water level reaches a low point swings the same rocker oppositely to close the same and open the valve, as will be readily understood. Or the ordinary flush tank valve mechanism may be used.

A short passage or chamber 12, extending the full width of the base and a short distance rearwardly to a point where trap 9 is suitably connected to it, guides the waste into the trap. Thus, the conveyor, during operation, continually delivers its load to the trap entrance leading to the sewer, in usual and normal manner. Slightly spaced from the side walls 2 the front bowl-wall 6 and the parts of the rear-bowl wall 5 through which the washing devices, hereinafter described, do not extend, are a plurality of downwardly extending travelling endless curtains 13 the lower ends of which dip into the water in the bottom of the closet bowl. These curtains are mounted on suitable upper and lower rods, shafts or rolls, of course, to maintain them in position and to drive them. The rolls, of course, are suitably mounted on the'walls in brackets or bearings of any desired kind. One of the rolls and one of the curtains may 'be driven by a sprocket chain 14 passed about a sprocket wheel on said roll.and about a sprocket wheel on a roll or shaft of the aforesaid conveyor II so that as the conveyor is driven, in a manner to be hereinafter disclosed, 6 that particular curtain will also be driven. From such particular curtain the other curtains may be driven in any suitable manner. Either sprocket and chain connections from one curtain shaft to another, or universal joints between shafts, or intermeshing gears carried by the shafts, or other suitable connections may be used. It will be understood that the particular drive shown is purely illustrative and that various other drives may be used, including any of those above mentioned. From the above,'it will be seen that practically the entire surfaces of the bowl walls are protected either by the travelling curtains or by the travelling conveyor, and that these curtains and the conveyor are continually or repeatedly washed or cleansed of waste, which waste passes immediately into the trap and sewer.

Preferably, the conveyor I I is driven by sprocket wheel and sprocket chain connections A, B, C, D, E and F from the fan or blower motor 24. To assist in cleansing the curtains, a set of sprinkler pipes 15 is provided. Preferably, they are so placed that jets from them strike the curtains as they approach the point where they turn to cross the top rolls or pass from the upward run to the downward run. These sprinkler pipes are connected to any suitable source of supply. The location of the sprinkler pipes relatively to the curtains and the direction of their jets is such that any substance remaining on the curtains as they reach the limit of their upper runs will be struck and driven off, at an angle, into the interior of the closet bowl to fall into the water in the bottom and settle onto the conveyor II, as will be readily understood. Preferably, a solenoid or other suitable electrically controlled valve 15' controls the flow of water to the spray pipes 15 and is actuated by the same circuit which actuates the blower 24, conveyor, etc. Thus, as the button 26 is operated, the flow of the sprinkler pipes Is started or stopped.

The rear portion of the base, extending from the rear edge of seat 8, when in operative position, to wall 4, is closed by a sliding cover 16, resting on suitable shoulders or guide ways of 2 and 4. It is -mounted in position to slide over and above seat 8 when seat 8 is in operative position.

When over 8, the bowl is completely closed and may be easily sterilized by turning in hot steam, hot water, or by applying anyone of a number of g5 chemicals, in well known manner. Seat 8 is mounted to slide to- and from operative position in the same manner as cover 16. They are both operable to and from their respective operative positions by screws 17 and 18, respectively, of well known construction and operation, and each driven by a small motor 19 or 20 controlled by a push button 21 or 22 in the box 23. Any other suitable mechanism for independently operating said screws may be used, of course. Preferably, there is a direct gear drive connection between each screw and the respective motor shaft, though a considerable variety of other drives may be used.

Either reversible motors or automatically reversing double spiral screws may be used, as will be readily understood, for reciprocating the seat and cover.

In order to quickly and thoroughly evacuate all odors from the bowl and closet, a suitable fan, blower or other means 24 is provided. It is mounted in the upper rear part of the base, above the upper end of the sewer connection and discharges into the lower end of a suitable vent pipe 25. It communicates with the interior of the bowl through one or more slot and/or openings or passages through all intervening walls. Preferably, this fan or blower is driven by a motor 24' controlled by a switch or push button 26 in box 23. In order to prevent back flow of evacuated foul air, when the fan is not operating, a suitable check 27 is used in pipe 25, beyond fan 24. That shown, is a series of pivotally mounted vanes arranged to swing open for passage of the odors carried out by the fan draft but to drop by gravity to closed position when the draft stops, and prevent back flow.

Preferably, embedded within seat 8 is a spray tube 28 having a plurality of upwardly directed jet passages. These jets are so directed through the seat, at such an angle, as to engage and wash the under side of the cover 16, along two sides and the front, when the cover is in closed position over the seat. Across the rear, the jets from the tube 28 are directed downwardly. In order to prevent operation of the jets of tube 28, except when the cover 16 is in closed position, the switch 29 of the electric valve 30 is placed to the rear of the seat 8 but close thereto, where it will be uncovered as cover 16 reaches the forward end or limit of its travel. Preferably, the switch 20 operates alternately to make and break the circuit for the valve. Thus, it may be manually operated to turn on the water, and actuated by the lug or finger 31 on the rear edge of the cover 16, as the cover moves back from its operative position. This arrangement prevents accidental operation of those jets, which could cause injury, if the water were dangerously hot, as for sterilizing. This will avoid accidental injury to small children, if the switch were where they could get at it. To permit seat 8 to slide back and forth and yet maintain communication with a water supply, either telescopic tubing or any well known type of .flexible tubing may be.used, establishing communication between 28 and the source of water supply. Both the top surface of seat 8 and the underside of the cover 16 will be wet by the spraying, of course. To remove this drip and moisture, a flexible wiper bar or blade 32 is provided on the forward edge of cover 16.

As the cover is moved rearwardly the wiper 32 strips or wipes all moisture from the seat 8 and through the .seat opening. And, too, a wiper bar 33 carried by the rear of the seat 8 engages and wipes the under face of the cover 16 at the same time, as will be clear. Preferably, switch 29 is set in a notch or recess in the side wall close to the rear of seat 8, in the path of travel of finger 31.

Instead of paper for use after a movement, washing and wiping devices are provided, as will hereinafter appear. The washing device for the anus comprises a telescopic tube, indicated as a whole, by 34. It is, preferably, hydraulically operated by a pump 35 driven by a motor 36 controlled by a reversing push button 36' in the box 23. As the tube 34, suitably guided and supported by and through partition wall 5, reaches its full extended position, a cup-shaped bowl 37 of rubber or similar material on the end thereof will fit snugly against the buttocks of the user around the anus and enclose a small area around the anus. As the tube 34 reaches its limit of extension a pivoted trip 39' drops by gravity into position and engages and rocks a pivoted switch 40 to break the circuit of the pump motor so that pumping will be stopped, and the tube will remain in that extended position until reversal is started by again operating switch 36'. For clearness trip 39' which would be in dropped or operative position in Fig. 2, is omitted from that figure because' it is shown enlarged and in action in the detail view, Fig. 7, on the same sheet, particularly illustrating that feature. 'This trip is pivoted near one end to the lower side of an Intermediate section of tube 34 and so located that as the tube approaches full extension it will be moved from the inoperative position between the two telescoped tube sections to a point beyond the enclosing section. As it passes beyond the edge of the enclosing section it is free to and does drop to the position shown in Fig. 7. Switch 40 is pivotally mounted in its path and is engaged almost immediately after it drops. In the remaining very'short travel to its final position, tube 34 carrying trip 39' rocks switch 40 to break the circuit and stop the motor of tube 3V. As tube 34 moves back and trip 39' is drawn between the tube sections, it will be swung up-to a position parallel with the tube. A mercury switch or anyother suitable type of make-and-break device may be used, of course. Switch 40 may be pivotally supported on a bracket, plate, angle plate or any other suitable device 40', desired. And, of course, as the fluid is pumped from the tube 34, in its reversal, it will be directed, in any well known manner,, into a tank or other reservoir from which the supply may be taken. And, when travelling in the rearward direction, trip 39, rigid on the outer end of the section carrying the bowl 31, will similarly engage and rock switch 40, oppositely, to break the circuit and stop the motor, as the tube reaches full retracted position. Thus, trip 39' will stop the motor as 34 becomes fully extended and trip 39 will stop it as it reaches its full retracted position.

SExtending in the same general direction as the telescopic tube 34 and so disposed that its-forward end may slip into and out of the bowl 37, through the opening or notch 57 of bowl 37, when that bowl is in its most forward position, is the. telescopic pipe or tube 41, the forward part of 45 which is provided with a plurality of small delivery outlets or perforations. Over this perforated portion is' secured a compressible, elongated, elliptical washer head 42 of rubber or Ssimilar material provided with a plurality of radially disposed outlets through which water flows in a series of streams, or, if the pressure is sufficient, in a series of small jets. The section of the tube carrying the head 42 is simultaneously revoluble and horizontally or longitudinally re65 ciprocable. For this purpose, it has lengthwise and revoluble free sliding mounting in brackets, a frame or any other desired type of supports within the base. For.driving said section of 41, the motor 43 is provided. Motor 43 may.be sup60 ported in operative position in any usual and well known manner, the support shown being a platform, shelf or floor 43'. This motor support may also readily carry the bracket 52' on which are mounted the switches 52 and 59 (Fig. 5), herein65 after more fully described. The power shaft or take off of the motor is provided with a squared section 44 and a section 45 having reversed spiral grooves for transmitting reciprocating motion.

A feed block 46, slidably mounted on a guide rod 0T 47 may be sleeved on 45 and provided with a lug, finger or the like riding in the ,grooves of 45, in well known manner. This block, of course, will be reciprocated lengthwise of 45 as 45 is rotated continuously in one direction, as is well 75 understood. As the motor 43 is started by pushing switch 48 in control box 23, block 46 will, immediately, start forward. After it has gone a short distance, finger 49 will engage a stop plate or disc 50 secured to 41 in any suitable manner to compel tube 41 to travel lengthwise with it.

From this point on, tube 41 will be carried forward to the end of the forward travel of block 46.

As the block 46 starts its reverse travel, finger 49 will leave disc 50 and tube 41 will remain in that forward position. As block 46 continues rearwardly, finger 49 will engage a second plate or disc 51, compelling tube 41 to move rearwardly or reversely from that point to the end of the reverse travel of block 46. As the block 46 reaches the end of its rearward travel, it will engage and operate a suitable trip switch 52 to break the motor circuit (wires a-b) and stop the motor. And, as will be readily understood, block 46, in its forward travel will similarly engage switch 52 and rock it to closed position.

Tube 41 is continuously revolved from motor 43 at all times during operation of the motor, by gear 53 keyed to the motor transmission or power shaft 44 to rotate therewith while being freely slidable therealong, said gear meshing with and driving gear 54 fixed to and slidable with tube 41. Gear 54 is provided with flanges 55 between which gear 53 passes in engaging 54. So, as tube 41 and its gear 54 are reciprocated, as above, gear 53 will travel with gear 54 and in continuous. engagement therewith. While the squared shaft is shown as the keying means, it is to be understood that any other siutable keying means may be used. And, of course, during the interval while block 46 travels from stop 50 to 51 or reversely, at the opposite ends of its reciprocation, this intermeshing of gears 53 and 54 will revolve tube 41 and head 42 without any longitudinal movement, for purposes to be later disclosed.

The rear wall of cup or bowl 37 is deeply. notched or recessed as at notch 57. The parts are so proportioned and arranged that the edge of 57 will press on and scrape 42 as it passes thereover, acting to squeeze out the water and scrape off any waste. Stops 50 and 51 may be adjustably secured to 41 by set screws or any other suitable nmeans. By spacing them at different distances apart, the duration or time of rotation of tube 41 and washer head 42, without longitudinal movement, may be easily regulated.

It will be understood that all waste water and matter scraped from 42 will pass into bowl 37 and through drainage openings 38 (Figs. 1 and 9) into the closet bowl and onto the conveyor II.

It is desirable, of course, to discontinue the flow of water through 41 and 42 while they are retracted and not in use. Accordingly, an electrically operated valve 58 of well known type may be installed at any convenient point in the line of supply. It may be automatically operated by a switch 59 (between wires c--d of an operating circuit) engaged and actuated by finger 49 on block 46. This switch may be suitably mounted in any well known manner in the frame, bracket or other part supporting the tube 41 and/or shafts 44, 45. It is so placed relatively to the finger 49 of block 46, that it will be engaged by finger 49 and operated to open the valve and supply water at the moment that tube 41 has completed its forward movement and will be reengaged by finger 49 and operated to close the valve and cut off supply of water at the moment that tube 41 starts reverse travel. A simple form of rocker'or bell-crank may be used, the rocker part having an arm at each end, that at one end, when engaged, rocking the bell crank to close the circuit and that at the opposite end, rocking to open. It will be so disposed.that the arm engaged in the rearward travel will be depressed below or beyond the path of travel of 49 but will 'be raised into that path as 49, in forward travel, engages the other.

Bowl 37 has been referred to as of rubber.

Preferably, it has a tubular inflatable rim or rib surrounding its top edge. Made in the form shown, it would be oval in top plan view, with the tubular edge 60 outlining it. A rigid dished supporting plate 62 having substantially the contour of the bottom of bowl 37, secured to the end of 34, acts as a backing for 37. It is provided with several notches or channels acting as keyways to receive corresponding keys on the bowl.

The keys and key-ways may, of course, be arranged reversely or vice versa. The bowl is molded with a series of communicating passages or channels 63 adapted to receive water through a telescopic tube 61 carried by suitable brackets from the underside of the tube 34. In the arrangement shown, there is a circumferential channel just below the edge 60, having a plurality of Jet openings, and a lateral or diametrical channel about mid-way of the length of the bowl and communicating with the circumferential channel at both sides. The pipe 61 extends along ,o the support 62 and between it and bowl 37, the bottom of the bowl being channeled or grooved to accommodate it, to the lateral channel of the bowl, to which it communicates. At a point between the lateral channel and the rear end of 3. bowl 37, pipe 61 is provided with a nipple 64 extending upwardly through the bowl and directing a washing jet upwardly therein. The nipple socket of the bowl is proportioned to give a snug holding fit. The same is true of the fit of the bowl on the end of pipe 6 1. So, as water enters 6 , there will be jets through the plurality of Jet perforations in the circumferential channel 63 and through the nipple 64, directed against and thoroughly washing those parts of the body with4. in the outline of bowl 37. It will be understood that both 41 and 61 may receive their water from the same supply and that valve 58 may control that supply. In that case, as finger 49 operates switch 59, water will be automatically supplied 5) to both 41 and 61, or automatically cut off therefrom.

As previously stated, the edge 60 of bowl 37 is tubular to fit the body. In order to insure a snug fit and to control that fit, it is cpnnected to a Ssuitable supply of air under pressure through a telescopic tube 65, an electrically operated valve 66 being provided to control the air supply to tube 60. Push button 67 in control box 23 makes or breaks the circuit for the valve, as will be understood.

That part of the body sprayed, as above, will, of course, be dripping wet. Incidentally, that part is, for the most part, covered with a thick mat of coarse hair which acts to hold the water.

STo quickly and effciently remove this water, a simple stripping device or wiper is used. This comprises an elliptical roller pad 68 of rubber or like material, over a telescopic tube as a support, the ends of the tube being journaled in the ends of long spring arms 69. These arms are shaped to extend downwardly and forwardly from their connection with the supporting plate 62, under the forward part of the bowl 37 and to a point slightly above and in front of the forward part of the tubular edge 60. The construction, mounting and spring or resilience of arms 69 is such as to hold them yieldingly spread, as shown, when the parts are in their forward or operative positions. However, the spring action of the arms is slight so that they are easily moved toward each other, no considerable force being required for that purpose. Assume that a user is occupying the seat 8, with the parts in the positions shown in the assembly views. As the spraying or washing operation stops, the user will push button 36' and start rearward travel of telescopic tube 34, bowl 31 and roller pad 68.

The pad will be between the legs of the user, somewhat above the crotch where, in sitting, the legs are somewhat spread. Moving rearwardly, the pad contacts and follows the lower part of the body. Also, in the rearward travel of the bowl, a pair of spaced plates 74, having lateral fingers, branches, ribs or the like 15 engage the diverging arms and force them toward each other, telescoping the mounting of the pad and compressing the pad 68. This increases its midlength diameter and shortens its length. In this way the pad will follow the contour of the body and yet will have its diameter and, therefore, its pressure increased. The parts are so proportioned that, as the bowl 37 reaches full retracted position, the ribs 75 of plates 74 will reach deep notches 76 in the sides of 69. This will enable arms 69 to spring back to extended position, again, with the pad 68 extended. By that time, the roller has passed completely beyond the body of the user, of course. Plates 74 may be secured in any manner desired to the wall 5, as will be well understood. This strips, squeezes and presses out practically all free water, leaving the body and hair substantially dry.

The roller pad 68 may mat down the hair on this part of the body. To overcome this, a stream of air issues upwardly and rearwardly immediately behind the roller pad in its rearward travel.

This current immediately loosens and.fluffs any hair that may have become matted and adds to the drying. Such a current may be supplied in various ways. The preferred way is to have a head 70 extended forward beyond pad 68 and so shaped as to direct the air flow continually against the part of the body which has just been passed over by 68. The air would flow to the jet head by a telescopic tube 7I from a suitable supply. Any well known electrically operated valve 72 may be used to control the flow, a push button 73 being provided in control box 23 to make or break the controlling circuit, in well known manner. The parts are so proportioned that pad 68 will lie, normally, within the space between tubular edge 60 and air jet head 70, projecting slightly above so that its spring arms 69 may exert the slight pressure desired. The space between 60 and 70 should be such that when 68 is between the two there will be a slight space between 68 and 70 for flow of air, the jet passages of 10 being so designed as to direct a current of air rearwardly and upwardly in a path directly in the rear of the pad as it travels toward the rear. Obviously, a switch could be used instead of a push button 73 and it could be operated by a lug or other device carried by either 71 or 34, to turn the air on as the bowl starts and cut it off as the bowl reaches the rear limit of its travel, or at some other intermediate point.

An additional telescopic tube 77 carried by 34 and leading to a nipple 78 may be provided so that an enema could be given through the bowl 37, It is, normally, closed by a cap 79 screwed thereon but removable for connection of the nipple to a syringe or the like. Tube 11 is suitably connected to the water supply with a valve 77' controlling flow therethrough and electrically operated through a circuit having a switch or push button 78' in box 23, all as will be readily understood.

The invention so far disclosed, is equally usable by either sex.

For use by women, there are additional fea,tures. After using the above anus cleansing devices, she will use the vagina cleansing means hereinafter set forth. A telescopic tube 80 similar to 34 is mounted in the partition 5 in the same way as 34 is mounted therein. It is disposed in approximately the same vertical plane as 34. It is operated by a pump 81, driven by a motor 82 which is operated by a circuit which is closed by a reversing push button switch 83. This circuit is broken by a suitable mercury or other swinging or other pivoted switch 84 engaged and actuated by a pivoted trip 85 carried by 80 and so disposed as to actuate 84 to break the circuit and stop tube 80 as it reaches its full extension, the rigid trip 85' carried by the outer end'of 80 engaging the switch and rocking it to break the circuit as tube 80 reaches its full retracted position, all as is the case with tube 34. Thus, as the tube 80 reaches the forward go limit of its travel, bowl 86 will fall into position to fit snugly against and about that part of the body immediately surrounding the vagina. To that end, it is shaped accordingly. The tubular edge 87, through telescopic air tube 88, may be inflated !.- from the same source of supply as for 60, an electrically operated valve 89 and push button 90 in the control box 23 being provided. As with edge 60, edge 87, by proper inflation, will fit snugly against the body. For washing that part of the body within the outline of the bowl 86, a set of spray channels or passages 91 is provided in the body of the bowl 86. Preferably, the set comprises a peripheral passage just below the tubular edge 87 and a lateral passage communicating with it, the peripheral passage having a plurality of jet openings through which washing streams or jets issue. Bowl 86, like 37, is supported on a curved plate 92 on the end of tube 80. A telescopic tube 93 supplies water from a suitable source to the passages of 86. An electrically operated valve 94, through a push button 95 in box 23 controls the flow to the bowl 86.

It should be pointed out that there is a wedge shaped ridge or rib 86' centrally disposed within the bowl 86, extending lengthwise therein and so arranged that when bowl 86 is in operative position the tip of the ridge will either aline with or enter the outer entrance of the vagina. This rib is provided with jet passages which communicate with pipe 93, and supplies several upward jets similar to the jet from the nipple 64 of pipe 61.

An air spray head 96 similar to 70 directs a current of air onto and through matted hair, immediately following the wiping roller or pad, as will later appear. Air may be supplied to the head through a telescopic tube 97 from an air tank or other source. The flow may be controlled by an electrically operated valve 98, a simple push button switch 98', in the control box 23 being relied on. While both bowls are provided with several drainage outlets, it is preferable to so regulate the flow as to maintain them as near full as practical throughout the times that they are in use.

In order to remove the drip and surplus water from that part of the body which has been washed, a sponge rubber or similar rubber pad or roller 99 is provided. It is mounted in spring arms 100 having substantially the same action, function and operation as arms. 69. Roller 99 is mounted similarly to the mounting of 68, on a telescopic tube in the ends of 100. Arms 100 have the same kind of spring action as arms 69: If desired, a coil spring may be disposed between the arms to add its force to the spring arms in keeping them, yieldingly spread apart. In order to contract the arms 100, as the bowl 86 moves rearwardly, a cable 101 is provided. It is looped about grooved guide rollers or passes through eyes carried on the ends of arms 100, etc. The opposite end of cable 101 is secured to a spool or other device on the shaft of motor 102 which is on the same circuit as motor 82 for telescopic tube 80 and, therefore, operates by the same button (83) as tube 80 for bowl 86. So, as tube 80 moves rearwardly, the cable is wound up, drawing arms 100 together and compressing roller 99.

Hair which has been more or less matted down by the roller can be immediately fluffed and lightened by the current directed against it by air spray head 96, the flow being controlled at the will of the user, as in the case of the air current following roller 68. Of course, the above rate of winding of the motor 102 is so regulated as to draw arms 100 together in synchronism with the travel of the tube 80. And, as the bowl advances, the cable unwinds reversely.

Of course, the air and water may be taken from any suitable sources of supply, such as mains, pipes, tanks, etc.

It is probable that a length of six inches with a width of four (outside measurements) will be ample for bowl 31, though that may be varied as desired, of course. A length of six, with a width of two, at the narrower part (outside measurements) probably, will be ample for bowl 86 though it, too, may be varied as desired. The total travel of bowl 31 will probably be less, considerably, than one foot. In its retracted position, as indicated by dotted lines, it is completely to the rear of the seat opening. The full line position is in place ready for use, but with roller 68 raised somewhat, because no one is on the seat to press the roller down. Bowl 86 on the other hand, will have to travel further forward to reach its operative position. It will have to travel about twice that distance. The full line position shows 86 retracted beyond the rear edge of the seat opening, while its forward or operative position is indicated in dotted lines. And, as will be readily understood and clearly seen, the full longitudinal travel of the rotary washer 42 is about equal to that of the bowl 31. None of the reciprocable parts are required to travel any appreciable distance. The travel of bowl 86, nevertheless, being about twice that of bowl 31 and washer 42. It will be well understood that the bowls 31 and 86 and immediately related parts are shown somewhat disproportionately large, for clearness, and that the air and water pipes carried by and beneath the tubes 34 and 80 are indicated more or less diagrammatically, for simplicity and clearness.

The operation of the invention is as follows: Preliminary to use, all parts will be in the positions shown in full lines in the assembly views, except telescopic tube 34 with bowl 37 and tube 41 with washer 42. They will be retracted to the positions shown in dotted lines. Starting with the parts in such retracted positions, a user takes the seat. After a movement, button 36' will be pushed to advance bowl 31 which will stop at the full line position as pivoted trip 39' rocks switch 40 to break the circuit of motor 36. If the edge 60 does not fit closely enough, button 67 will be pushed to further inflate the edge. Then motor 43 will be started by button 48. As it starts, shafts 44, 45 will be driven, rotating washer 42 and, at the same time causing block 46 to travel forward. As it does so it leaves stop 51. Continuing, block 46 will engage stop 50; from which point it will carry tube 41 and washer 42 forward through notch 51 to the full line position. Actually, it is finger 49 that engages discs 50' and 51, not block 46. At the predetermined point in the forward travel, finger 49 will also engage and operate switch 59 to open valve 58 and turn on the water supply through 41 and 61. And, of course, that supply is cut off by finger 49 engaging the same switch in its reverse travel. The parts are so proportioned that at that point the reverse spiral screw thread starts block 46 back. As it starts back it leaves stop 50. In its travel from 50 to 51, its finger 49 is inoperative so that tube S41 and washer 42 continue to rotate but do not - move longitudinally. During this rotation, washer 42 is in contact with the anus which it washes thoroughly. It will be seen that during rotation of 42 there is a continuous flow of jets on and over the parts within the bowl 37 and through the washer. As finger 49 engages stop 51 it will carry 41 back with it. As 42 comes back through notch 57, it will be squeezed and pressed so that any adhering matter will drop onto the conveyor it and be removed. As the block 46 reaches the rear limit of its movement, finger 49 will operate switch 52 to break the circuit of motor 43.

Then the user will operate push button 36', again, starting motor 36 in reverse and operating pump 35 in reverse to return tube 34. As stop 39 on 34 trips switch 40, the bowl 37 will have reached its dotted line position or starting point and be ready for its next advance. As the bowl moves rearwardly the spring arms 69 of the sponge rubber roller or pad 68 force it against the lower part of the body for the full width between the legs, contact with the body forcing the roller down.

There is a rolling and pressing or squee-gee action to press off all dripping and wetness. Any 50matted condition of the hair is corrected by the air current from 70, the user controlling this cur'rent by button 73, during retraction of the bowl 37. If the user is a man, he may then rise, thoroughly cleansed and substantially dry. On rising, he should push button 26 controlling the fan or blower motor, conveyor, curtains, and spray pipes 15 for the curtains. He should also push the button 56 marked "flush" in the control block or panel 23. Those two buttons will start the fan to remove the foul air and odors, the conveyor to remove the waste, the curtains to cleanse the bowl, sprays 15 to cleanse the curtain, and the flush. The switches for the fan and for the flush may be of a well known type to cause operation for a limited period of time, only, and then shut Soff, as is well understood. In the case of the flush, the push button may be the usual button of the standard flush device well known on the market, the button simply actuating the spring controlled valve having a predetermined delayed action.

If a woman has used the toilet, in addition to the above, before rising, she will push button 83.

As 86 comes into position, pivoted trip 85 will 1 76 actuate switch 84 to stop motor 82, Then she may push button 90 to tighten edge 81. Then she will push button 95 for flow of water-through 93 and 91. Next she will push button 83 again to reverse tube 80. As the bowl 86 moves back and pad 99 removes the drip and free water, she may operate push button 98' to control the air current for loosening and flufing the matted hair in the rear of the roller. It will be understood that instead of push button 98' a switch may be provided, actuated by a lug or suitable trip carried by tube 80 and so disposed as to operate the switch to turn on the air as the bowl starts back and to turn the air off as the bowl reaches the, limit of its travel, if desired. As the tube 80 reaches its rearward limit, trip 85' will actuate switch 84 to stop motor 82. Then the user may rise, thoroughly cleansed and substantially dried.

Next, she would press the flush button and the button 26. The toilet is now ready for the next user. At intervals, the seat cover should be washed.

The attendant in charge will then push button 21 until cover 16 is in closed position. As cover 16 approaches its closed position, switch 29 will be uncovered and may be operated by the at- 25. tendant to open the valve supplying water to 28.

After an interval of spraying, the button 21 or switch will again be pushed causing reversal of the cover. As the cover starts back lug 31 will engage 29 and close the valve, cutting off the supply. In the rearward travel of cover 16 the wiper bar 32, of well known construction, will engage and wipe or strip from the top surface of the seat 8 all moisture. At the same time, a wiper bar 33 carried by the rear of seat 8 will similarly .i strip or wipe all excess moisture from the under side of the cover.

It will be understood of course, that while the cover is in the closed position, the space beneath, or the interior of the base, may be readily disinfected in any suitable manner, as for instance, by turning in live steam, hot water, or using chemicals.

At intervals, it may be desirable to slide seat 8 back out of the way for repair, removal of parts, renewal of the curtains 13, or for other purposes. At such a time, the attendant simply presses button 22 until seat 8 has been moved rearwardly as far as desired. After making the repairs or performing any other operations or duties desired, the attendant again pushes the button and the seat returns to the position shown in full lines. Here, again, the double spiral screw feed may be used, as explained for the cover.

Since the specific wiring from the switches or push buttons to the various elements controlled by them, such as motors, valves, etc., is no part of the present invention, but standard and well known, and since the same is true of the various switches and valves, no diagrammatic drawing of 6g the circuits or details of the switches or valves has been shown, as it is believed that such illustration of well known devices would incline more toward confusion than toward clearness.

It will be readily understood that any suitable materials may be used for any of the parts of the invention and that all such are included in this application. Likewise, there are various kinds and arrangements of switches and valves any of which may be thoroughly applicable to the particular purpose and operation mentioned and it is intended to include all such within this application, within the scope of the appended claims.

It will be clear, too, that a single power unit (motor) may replace two or more in several instances by rearrangements within the scope of the invention, and it is meant to include all such within this application.

Many changes may be made in the construction, arrangement and disposition of the various parts of the invention, within the scope of the appended claims, without in any degree departing from the field of the invention, and it is meant to include all such within, this application wherein only one preferred form has been shown purely by way of illustration and with no thought of, in any way or degree, limiting the invention by such illustration.
