Description:

The present invention relates in general to improvements in the construction of plumbing fixtures or fittings, and relates more specifically to an adjustable shower-spout fixture for tubs and other wash receptacles, which can be manipulated and adjusted for use as an elevated shower spray fixture, or as a lowered filling or rinsing spout.

Heretofore, it has been common to provide combination bathtubs and shower appliances, but all of such installations required an excessive amount of plumbing work and many fittings and fixtures. For instance, a common example is an installation wherein the tub is provided with the usual water spout and flow therethrough is controlled by valves having projecting handles. Weth this form of installation there/is an elevated shower spray head, through w ich the flow of water is controlled by separate vyaes and handles. As an alternative of this arrangement, a mixing valve may be provided for the tub spout and another mixing valve for the shower spray head. Obviously, a great number of fittings and fixtures are required, and the tub has the spout and fixtures projecting thereinto and forming fixed obstructions and protuberances.

It is, therefore, a general object of the present invention to provide a single, convertible showerspout fixture, and a single set of control valves (or a mixing valve) therefor, which will serve for bathtub spout and shower spray purposes, eliminating the expense and objections incident to the use of multiple fixtures for the same purpose, as heretofore described.

In certain forms of plumbing installations for large buildings, wherein washing units are vertically superimposed, considerable difficulty is sometimes encountered with back siphonage resulting from over-filling of one of the washing receptacles, above the water supply spout thereof. With the present invention this difficulty is overcome due to the fact that fixed spouts within the tub or other washing receptacle are eliminated.

A specific object of the invention is to provide a convertible and adjustable shower-spout fixture, which, while serving for both shower and tub purposes, requires but one water discharge member and one set of valves (or a mixing valve), thereby materially reducing the number of parts and fittings heretofore required in tub-shower installations.

Another specific object of the invention is to provide a plumbing fixture for use with a bathtub which can be used as a shower spray to spray water onto a person's head or which can be manipulated to spray a portion of a person's body without wetting the head, which can be adjusted to spray any portion of the human body normally difficult of access, or which can be used as a spout for filling, rinsing, or flushing a tub.

Still another specific object of the invention is to provide a convertible bathtub fixture which can be changed from a shower spray head to a spout by a simple manipulation, and in the latter case it can be used for filling a tub in the ordinary manner.

Another specific object of the invention is to provide a combination bathtub shower-spout fixture, which eliminates the necessity for fixed fittings projecting through the walls of the tub which mar the smooth interior of the tub.

Other specific objects of the invention are to provide a bathtub fixture of the character described which is simple in construction, which may be conveniently installed, assembled, or dis- 16mantled, which is easy to manipulate and adjust, and which is highly effective and efficient in operation.

These and other objects and advantages will be apparent from the following detailed description.

A clear conception of an embodiment of the improvement and of the mode of constructing, manipulating, and operating devices constructed in accordance therewith may be had by referring to the drawing accompanying and forming a part of this specification, in which like reference characters designate the same or similar parts in the various views. Fig. 1 is a fragmentary, perspective view of a bathtub and adjoining wall portions and showing the improved shower-spout fixture installed over one end portion of the tub, there being broken-line showings of various positions of adjustment of the fixture; Fig. 2 is an enlarged sectional view through the upper knuckle joint member and the sprayspout; Fig. 3 is a transverse sectional view taken on line 3-3 of Fig. 2; Fig. 4 is an end view of the spray-spout; and Fig. 5 is an enlarged side view of the lower knuckle joint member and the mounting plate therefor.

While'the invention has been shown herein as being speciflca~y applied to a bathtub, it will be apparent that the novel features are more generally applicable to other styles of tubs, containers, shower stalls, sinks, and the like.

Referring now more particularly to the draw- 0 ing, it will be apparent that a d6nventional bathtub of the "built-in" type is indicated by the numeral 8, and adjoining end and side walls of the room wherein the tub is installed are rep- 5 resented by the numerals 9 and 10, respectively..

The tub is provided with the usual bottom drain opening II and an elevated overflow opening 12. Hot and cold water pipes 13 and 14 extending from a source (not shown) are concealed rearwardly of one of the walls 9, and within said pipes are hot and cold water co trol valves 15 and 16 operated by valve rods a handles 17 and 18 projecting exteriorly of t wall 9, a suitable distance above the tub. In li A of the separate valves and valve handles it obvious that a conventional form of mixio valve may be used, if desired. Above the valv 15 and 16 the hot and cold water pipes mer2 into a single pipe 19 which extends upward a suitable distance and then is extended angi larly through the wall 9 at a considerable elev tion with respect to the tub.

A bracket plate 20 embraces the outward projecting portion of the pipe 19, and said pla is secured to the outer surface of the wall The bracket plate carries a lower knuckle Johi member designated generally by the numer 21. Said knuckle joint member is similar in cox struction to an upper knuckle joint member 1 shown in detail in Figs. 2 and 3 and to be d« scribed fully hereinafter. Suffice it to say thi the knuckle joint member 21 is composed of tw relatively movable sections having fiat engagin surfaces and pivotally held together by a pil 23. The end of the pipe s1 which is embrace by the bracket plate 20 opens into a holloi reservoir within the knuckle joint, and throug] certain ports water is discharged into a boss 2 into which is threaded the inner end portio] of an elongated, rigid, tubular connection 21 The other end portion of said connection 25 1 threaded into a boss 24' on th knuckle n oint.22 With special reference to Figs. 2 and 3, it wil be observed that the knuckle joint member 2i includes a substantially semi-spherical section 21 which is integral with the boss 24'. Said section 26 has a flat face which is in engagemeni with a flat surface on a complementary, semispherical section 27, the latter section having an integral, externally threaded stem 28 provided with an interior duct 29. There is a pair of ducts 30 in the section 26 establishing communication with the tubula eer member 2, at one end; and said ducts, at their other ends, open into a chamber 31 in said section 26. Said chamber is complementary to a smaller chamber 32 in the section 27 which communicates with the inner end of the duct 29. The sections 26 and 27 are pivotally held together by a pivot pin 33 extended through a central portion of the section 27 and threaded into a portion of the section 21. Within a recess 34 in the section 27 and surrounding a portion of the pin 33 there is a tension spring 35. This spring is seated against 65 the inner face of an adjustment cap 36 on the outer end of the pin, and said cap may be turned in either direction to vary the tension of said spring. Adjacent the meeting portions of the flat faces of the sections 26 and 27, disposed in gO suitable recesses, is a sealing ring or washer 37 to prevent leakage between said sections. As previously mentioned, the knuckle joint member 21 Is exactly similar in construction to said knuckle joint member 22, the only difference being that the tension spring employed in the member 21 is somewhat heavier and stronger than the spring 35 employed in the member 22.

Threaded onto the outer end portion of the stem 23 is a spray-spout member indicated generallyby the numeral 38. Said member consist of a bell-shaped outer head 39 with a hollow interior. Spanning the inner chamber, inwardly from the discharge end, is a rib or plate 40 having a bored, Internally threaded, ^ central opening to turnably receive a threaded n- stud 41 projecting inwardly from an adjusting nd disc 42. The head 3o is formed interiorly with he an annular, slightly inwardly tapered seat 43 eu to receive the disc 42, whose side wall portions is are also similarly tapered. Adjacent said ta- rt ng pered side wall portions the disc is provided with 'es a plurality of discharge grooves or recesses 44, ge which grooves only become entirely enclosed or ly surrounded by stock when the disc is seated in - its innermost position. The outer face of the utr t10 a- disc is provided with projecting wings 45, by which means the disc may be manually turned ly into tight engagement with the seat 43, or outte wardly removed therefrom. When the disc is 9. tightly seated, the recesses 44 become spray it orifices; and the member 38 functions as an oral dinary shower spray head, discharging a plu- rality of minute streams. However, if the disc !2 is slightly loosened, the recesses 44 become in- effective; and water discharges through the anrt nular space between the disc and the seat. As o thus adjusted the member 38 issues forth a solid g stream of water as an ordinary spout. n Obviously, the section 21 of the knuckle joint d member 22 may be turned in a single plane relaN tively to the section 26, and as the section 27 h -carries the spray-spout member, arcuate adjust4 ment of the spray-spout may be readily atStained, the force required to adjust said memi. ber 3t being determined by the tightness of the s cap 36.

The flow of water through the apparatus is as 1 follows: Assuming that both of the valves IS and IS are opened, water flows from the pipes 13 and 1 14 into the pipe 19 and mixes therein, as well as Sin the subsequent connections. From the pipe 19, Sthe water flows into the knuckle joint member 21, Sthrough the chambers and ducts therein, and then into and through the elongated connection 2. From the outer end of the connection 25 the water passes through the adjusted knuckle joint member 22 and then is discharged by the sprayspout member, either in a solid stream or in a plurality of minute streams as a shower, depending upon the adjustment of the disc 42. The 4 tubular member 25, carrying the spray-spout, may be swung arcuately in a plane on the inner knuckle joint member 21; and the spray-spout may be separately adjusted on the other knuckle joint member 22. With the improved apparatus installed as 50 shown, all of the fixtures and fittings are a substantial distance above the bathtub. and nothing normally projects directly into the tub so as to break the smooth continuity of the inner walls thereof. If the apparatus is to be used as a shower bath, it may be adjusted in a manner similar to the full-line position or the first adjacent broken-line position in Fg. 1; and the disc 42 should be tightly seated so as to issue shower streams. For shampooing or showering other portions of the body the device may be manipulated to other intermediate positions, and it may be adjusted to spray any portions of the body. A person may stand in the tub or be seated exteriorly of the tub and lean over the latter. In a lower position of adjustment the device may be used to rinse or flush out the tub and, also, if the disc 42 is turned outwardly slightly, the head 38 will issue an ordinary 7o spouted stream of water; and in this manner the tub may be filled in the same manner as the ordinary tub bath.

The device is of particular advantage and is inexpensive to manufacture and Install in that It 3,011,446 eliminates one complete set of valves and spout spm necessary in the former combination shower and dull tub installations; and due to the fact that there pie is no fixed spout within the wash receptacle, the danger of back siphonage is entirely eliminated. thr The adjustability of the shower head through- din out a relatively wide range also makes it possible ove to use the improved assemblage without excessive wit splashing, even if the ordinary shower curtain is ' dispensed with. While the improved plumbing jac fixture has been shown and described herein as spi being specifically applied to a washing receptacle du designated herein as a "bathtub", it is the intent pi to have this term, wherever employed, cover other thi types of wash basins. The entire structure is th unique and attractive in appearance and may be di manipulated and adjusted with the greatest of of ease, and has demonstrated its practicability in as actual use. in It should be understood that it s not desired to limit the present invention to the exact details of of construction and operation herein shown and described, for various modifications within the ia scope of the claims may -occur to persons skilled at in the art. ir What is claimed as the invention is: t 1.
