Description:

My invention relates to an apparatus for mixing embalming solutions preparatory to injection of the same into a corpse.

In the present day practices of embalming dead bodies, concentrated solutions of embalming fluid, usually marketed in glass jars or containers, is diluted according to the individual subject upon which the same is to be used. This mixing operation is usually done in a crude way by mixing in jars with no adequate way of making the proper proportionate mixture, particularly when it is attempted to add to solution remaining from previous operations. A further objection to this common practice is that the solution is fre13 quently spilled on the hands or clothing of the operator or on other objects with objectionable results. It is very desirable to be able to vary the strength of the embalming fluid even during the embalming operation, as during such operation it is necessary to watch the body for evidence of ill effects produced by the embalming fluid which are due primarily to conditions of the body previously caused by the nature of the ailment which caused death and the fact that the solution has not been properly proportioned to meet the particular condition of the body.

The principal object of my invention is to produce embalming apparatus of the class described of simple form and construction by means of which the concentrated embalming fluid may be exactly mixed with water to produce the desired solution and which apparatus may be readily adjusted during the embalming operation so that the mixture may be varied as circumSstances may require.

Other objects and advantages will appear hereinafter from the following description and drawing. Referring to the drawing, which is for illustrative purposes only-Figure 1 is a diagrammatic sectional elevation 40 showing an apparatus embodying the form of my invention; and Figure 2 is a sectional view on line 2-2 of Figure 1.

More particularly describing the apparatus shown in the drawing A represents a jar or reservoir containing the concentrated embalming solution; B a water supply from the ordinary pressure water system; C a water motor; D a ,50 pump; and E a mixing chamber. The abovementioned parts are the general features of the apparatus and are used with proper connections for utilizing the pressure of the-water supply by means of the water motor to operate a pump which pumps regulated portions of the concentrated solution to the incoming water where it is introduced into the water stream after which the mixture passes through the mixing chamber under pressure to a suitable injector by means of which the fluid is introduced into the body. The numeral II indicates a connection to the city water supply, not shown. This connection is provided with a conduit 12 through which water under pressure is supplied to the apparatus.

For the purpose of automatically controlling the supply of water through the conduit 12 a needle valve 13 is provided which engages a seat 14 to shut off such water supply as will hereinafter be more fully described. The conduit 12 is connected to the valve chest 15 of the water motor C, the conduit 12 terminating in a distributing port 16, controlled by a reciprocating valve member 17. The valve chest 15 is provided with ports 18 and 19 which connect respectively with passages 20 and 21 at the ends of a cylinder 22, the passage of liquid from the conduit 12 through the ports I8 and 19 is controlled by the position of an annular channel 24 in the valve member 1T.

As shown in the drawing the position of the channel 24 is such that fluid from port 16 is discharged through port 18 to passage 20 then into the cylinder at the rear of piston 25. The outer ends of the passages 20 and 21 are in open communication with a conduit 26 connected to a diversion valve 21. The introduction of fluid to the rear of the piston, as just above described, causes the piston to move in the direction of the arrow until it reaches the end of its stroke and during such movement operates mechanism, hereinafter more fully described, which moves the valve member 17 so that an annular channel 28 which is now in position to permit flow of fluid from in front of piston 25 to the conduit 26 moves into a position which closes the passage 21.

At the same time that this takes place a channel 30, in the valve member 17, moves into position so that the passage 20 is opened and the channel 24 moves into position, closing the port 18 and opening the port 19 so that the incoming fluid under pressure from conduit 12 passes to the front of the piston and moves it in opposite direction to that above described.

The piston 25 is fixed to a piston rod 32 which extends through the ends of the cylinder 22, one end of the piston rod extending into a pump cylinder 33 and the other end extending into a mixing chamber or cylinder 34. The piston rod has secured thereto a piston 35 in the pump cylinder and a piston 36 in the mixing cylinder, the piston 36 in the mixing cylinder being provided with openings 37 to permit some of th liquid in the mixing cylinder to pass through th piston as it reciprocates for the purpose o thoroughly mixing the fluid therein.

6 The means provided for reciprocating the valv member 17 consists of the following mechanism Secured to the piston rod 32 is an arm 40 ter minating at its upper end in a yoke 41 whicl engages a circular flange 42 on the end of valve sleeve 43 which reciprocates in the valvi chest 44 of the pump 33. The valve sleeve 4; has the same length of reciprocating movemeni as the piston rod 32 but it is pointed out thai the valve member 17 has a comparatively short movement. To provide for this difference ir movement, the valve sleeve 43 is provided with a slot 45 into which extends a pin 46 on the outer end of the valve member 17, which end of the valve member is slidably received in one end of the valve sleeve 43. The slot 45 is less in length than the stroke of the piston rod 32 so that the pin 46 is not engaged by the end of the slot 45 until the piston 25 has nearly reached the end of its stroke, at which time the end of the slot moves the pin 46 and valve member 7I a proper distance to bring the channels 24, 28 and 30 of the valve member into proper relation with the ports and passages of the valve chest 15 as heretofore described. To insure proper positioning of the valve member 17 a spring latch, Indicated at 50, is provided mounted at the end of the valve chest 15, which latch engages in Vshaped grooves 51 formed in the end of the valve member 17.

With respect to the feeding and proper mixture of the concentrated embalming fluid, a cup .55 is provided, which in the form shown, receives an upturned bottle or glass jar 56 of concentrated embalming fluid. The fluid emptied into the cup from the jar passes downwardly through a conduit 57 and passage 58 to ports 59 and 60 in the pump cylinder 33. These ports are arranged at the opposite ends of the cylinder and are controlled respectively by ball valves 61 and 4, 62. Ports 64 and 65 are also provided at the opposite ends of the cylinder 33 which connect with a passage 66 which is in open communication with a conduit 87 connected at its other end to the valve 27. The ports 64 and 65, where they 6o enter the passage 66, are controlled respectively by ball valves 70 and 71. Inside the ball valves 70 and 71, the ports 64 and 65 are in open communication with ports or passages 72 and 73, which at their outer ends communicate with the .-, valve sleeve 43. Cooperating with the ports 72 and 73 is a V-shaped communication port 75 in the sleeve 43 which according to its rotative adjustment, regulates the length of time the ports 72 and 73 are in open communication with each no other through the port 75 during the reciprocation of the valve sleeve 43. For the purpose of rotatably adjusting the valve sleeve 43 the outer end of the valve sleeve is provided with a longitudinal groove, indicated at 76, into which exc. tends a spline 77 on an adjustable plate 78. The adjustable plate 78 is provided with a slot 79 through which extends a tap screw 80 threaded into the valve chest 44.

It is to be noted that the diameter of the pis7~ ton 35 in the cylinder 33 is considerably smaller than the piston 25 in the motor cylinder 22 so that the water pressure moving the piston 25 is sufficient to cause the piston 35 to move the liquid from the pump cylinder 33 through con7. duit 67 to the valve 27 where, when the valve e is in the position shown in full lines, the conduit e communicates with a passage 82 in the valve f and conduit 83 into the incoming stream of water through conduit 12, the mixture there taking e place constituting the fluid heretofore referred : to as entering the cylinder 22.

Further explaining the action of the piston h 35 in the cylinder 33, as the piston moves in the a direction of the arrow from its shown position, e valve 61 is opened, valve 62 closed, valve 70 closed 1n 3 and valve 71 opened. The fluid in front of the t piston 35 is forced largely through port 65 and passage 73 to the port 75 in the valve sleeve, Sthence returned to the back of the piston through Sport 72 and port 64. The amount of such solution permitted to by-pass in the manner just described, regulates the amount of fluid that passes through passage 66 and conduit 67 to the valve 27. On the return movement of the piston the operation of the valves is the opposite to that just described, producing the same effect of by-passing the large proportion of fluid from one side to the other and pumping a small regulated amount to the valve 27 and thence to the incoming water heretofore referred to. As heretofore described, fluid from the cylinder 22 is discharged through conduit 26 to the valve 27. This valve 27 is of the rotative type and in addition to the port 82 heretofore referred to, is provided with a port 85. This port 85, when in the position shown in full lines, provides open communication between the conduit 26 and a conduit 86 which connects with the cylinder 34. The fluid passing through the conduit 86, that is, water with the desired proportion of the concentrated embalming solution mixed therewith, is thoroughly mixed in the cylinder 34 from which it is discharged through a connection 88 to a nozzle 89 in a glass container forming a pressure indicating chamber 90 which serves as a sight flow and pressure gauge. The inner end of the nozzle 89 is directed laterally and is provided with an annular lip 91 so that the discharge of fluid or rate of flow through nozzle 89 is clearly visible. From the container 90 the fluid is conducted by means of a conduit or pipe 92 and hose 93 to an injection needle 94.

It will be understood that during the operation of pumping the embalming fluid into the body that obstructions are sometimes encountered which must be met by proper regulation of the apparatus and it is for this purpose that the glass container 90 is provided as by the level of the liquid therein, any rise in pressure would be immediately indicated and if necessary the operation 15 of the apparatus immediately discontinued. The numeral 95 indicates a pipe or conduit connected to the valve 27 which preferably is provided with a hose connection not shown, to the sink or sewer.

It will be noted that by turning the valve 27, (0 so that the port 85 registers with the valve inlet of conduit 95 and with conduit 26, fluid from the cylinder 22 may be pumped directly into the sink. The same movement of the valve 27 will bring the port 82, as shown in dotted lines, into ti 5 registration with conduit 67 and a passage 96 which is in open communication with the conduit 86. When this manipulation of the valve has been accomplished the cylinder 22 and piston act only as a pressure pump and it will be noted that straight solution from the pump cylinder 33 is pumped directly into the mixing chamber or cylinder 34 through the container 90 into the body undiluted by mixture of water therewith. At this point it is noted that with an I , apparatus so arranged other uses for the apparatus are apparent as for instance, concentrated solutions in the form of preservatives or curing materials may be injected directly into meats such as cornbeef and that for such purposes the desired mixture may be produced by manipulation of the apparatus above described when the undiluted solution is not desired.

Means are provided for permitting automatic shut off of the apparatus when the desired amount of fluid has been pumped into the body. This is accomplished by means of a ratchet wheel 100 mounted on a shaft 101 which is engaged by means of a dog 102, mounted on a shaft 103, the dog having an extension in the form of an arm 104 which is adapted to be engaged by the flange 42 on the valve sleeve 43 when it reaches the end of its stroke as shown in the drawing. The arm 104 is so operated at the end of each stroke until the dog 105 engages the needle valve 13 moving the same against the valve seat 14 thereby shutting off the supply of water under pressure with a consequent stopping of the apparatus. The dog 105 is mounted on the shaft 101 and secured in adjusted position thereon by means of a nut 106. The dog is provided with markings, such as indicated at 107, which designate measured quantities of liquids, such as pints or quarts, and by adjusting the dog on the ratchet wheel 100 with respect to an indication thereon designated at 108 the dog may be arranged to engage the valve 13 when a predetermined amount of liquid has been passed through the apparatus.
