CORPORATION 01* wIsooNsIN OQMPARTMENT snownn BATH Application filed October 20, 1930.

This invention relates to improvements in compartment shower baths.

The present invention constitutes a modification of the subject matter of U. S. Patent No. 1,747,838, dated February 18th, 1930, wherein is disclosed a compartment shower bath of circular form providing for a pluralityof associated compartments of sectorlike form. 1

The construction in the afore-mentioned patent provides acompact arrangement for a plural number of associated shower compartments, minimizing in the frame-work and fittings required, and permitting a common supply and drain for all of the shower compartments so grouped, with individual valve controls for each shower compartment.

Insofar as the present structure follows 53 the prior arrangement, the objects and advantages residing in the prior construction are also attributable to the present invention. In the present invention, however, a mixing chamber common to all of theshower compartments is mounted on the upper end portion of the central post and; the

various discharge nozzles extend radiallyfrom the common:- mixing chamber into their respectlve shower compartments and are provided wltlrseparate control valves.

This arrangement lends itself very advantageously to the use'of overhead supply pipes which may benecessary in many installations. construction may be used to equal advantage where supply pipes from below are required. 1

1 A further object of-the invention is to provide a compartment showerbath which maybe readily trapped and vented.

A. further object of the invention is to provide a circular type compartment shower bath which is of very simple construction and arrangement, may be installed in a minimum amount of. space, is relatively inexpensive, is strong and durable and is well adapted forthe purposes set forth.

I Vith the above andother objects in view, the invention-consists of the improved compartment shower bath, and its parts and On the other hand, the present.

combinations as set forth in the claims, and all equivalents thereof.

In the accompanying drawings in which the same reference characters indicate the same parts'in all of the views:

Fig.1 is a side view of the compartment shower bath with parts broken away and in sectionp Fig. 2 isa plan View thereof;

Fig.3 is 'an enlarged vertical sectional view of the central support, mixing chamber, valves and associated parts, taken on line 33 of Fig. 4; I r

Fig. {L is a view taken on line 44 of Fig. 3, with portions broken away and in section to show details of construction; and

Fig. 5 is an enlarged, fragmentary verticalsectional view of the lower portion of the central standard and base showing an alternative supply pipe arrangement.

Referring now more particularly to the drawings it will appear that the compartment shower bath includes a tubular framework comprised ofjfive upright tubes 8 arranged at equal intervals in circular formation and having their lower end portions suitably-embedded in or secured to a dished concrete slab '9. A central hollow standard 10 also has'its lower end portion secured to the slab 9 and the upper end portion of said standard extends centrally into' a hollow mixing chamber casing 11, of circular form in horizontal section. The inner ends of top frame arms 12 are threaded into spaced-apart bosses 13 formed on the sides of the casing 11, and said arms, five in numher in "the form shown, extend outwardly radially horizontally. The outer ends of said arms 12' are engaged by fittings 14 on the upper ends of the tubes 8 and the fittings also secure to the adjacent frame-work members an annular ring tubing 15 which surmounts the tubes 8. The tubes 8, stand-' ard 10, arms 12 and ring 15 form a frame for partitions 16 which divide the ensemble into five compartments. Curtains (not be draped from the ring 15.

As before, 'mentioned,nthe mixing chamber ,casing .11 islocated at the upper end of 1 shown) for thevarious compartments may the standard 10. The interior of the mixing chamber casing is divided by a horizontal partition 17. Also spaced apart vertical partitions 18 between the bottom of the casing and the inner partition 17, divide the lower interior portion of said easing into. a plurality of sectorshaped mixing chambers 19. Between the partition and top of thecasing, inwardly of the outer side of the casing and concentric therewith, is an annular wall 20 dividing the upper interior portion of the easing into annular hot and cold water chambers 21 and 22 respectively. Hot and cold water supply pipes 23 and 2st, preferably depending from above, enter the casing so as to discharge into chambers 21 and 22 respectively.

Each portion of the horizontal partition 17 forming the top wall of each mixing chamber 19, is formed with a pair of ports 25 and 26 respectively between the chamber 19 and the upper chambers 21 and 22., each of said ports being controlled by a separate valve. Inasmuch as all ofthe valves and their associated parts are identical, only one will be described in detail. Depending from the partition 17 and surrounding a port 25 and its seat portion 25 is a cupped 6, and cold water to the corresponding mixing cylinder 27 extending through the lower wall of the casing, said cylinder being internally threaded. In threaded engagement therewith is a disc 28 fast on an inner portion of a valve stem 29 and the extreme inner end of the valve stem carries a valve 30 to seat and unseat with respect to the portion 25 and control the port 25. A bonnet 31 is threaded onto the external portion of the cylinder 27 and threaded into said bonnet, with the valve stem extending therethrough, is a packing mat 32. The lower end of each valve stem carries a manipulating handle, those for the hot water valves being designated 33, and the handles for the cold water valves being designated 34. Each cylinder 27 near its upper .end portion, is formed with a line of apertures 35, through which water admitted thereinto fromthe chamber above, when the valve 30' is in open position, may flow outwardly into the mixing chamber to be tempered and ultilnately discharged. Side portions of the mixing chamber casing 11, adjacent each mixing chamber 19 are formed with radially projecting bored bosses 36 into each of which the inner end portion of a short discharge pipe 37 is threaded, there being one discharge pipe for each mixing chamber and each corresponding compartment of the shower bath ensemble. The outer end portions of the pipes 37 carry depending spray nozzles 38. Obviously, the valve handles for each compartment, when turned to open their respective valves a certain distance, permit the admission of hot chamber. The tempered water then flows outwardly through the pipe 37 and is discharged in a spray into the shower bath compartment.

Surrounding the lower portion of the standard 10 which is embedded in and extends through the slab 9 is an apertured drain member 39 which discharges into a trap 40 connected to the lower end of the standard below the slab. Extending outwardly of the trap is a discharge or drain pipe ll. Said trap may also be provided with a vent pipe 42 extending upwardly through the tubular standard 10.

Fig. 5 illustrates an alternative arrangement wherein a water supply from below is desired. In this arrangement hot and cold water supply pipes 23 and 24 extend through a fitting on the lower portion of the standard 10 below the slab, and then continue vertically upwardly through the standard and connect at their upper end portions with convenient portions of the mixing chamber casing at the upper end of the standard.

The improved compartment shower bath, because of its circular arrangement provides for a maximum number of individual shower compartments within a minimum amount of space, and the structure further minimizes the fittings, pipes, partitions and otherv requirements. Further, with the mixing chamber casing located at the top of the standard, the water supply may bebrought either from above or below. The annular arrangement of the mixing chamber casing permits location of valve controls within each compartment, easily accessible.

From the foregoing: description, it will be seen that, the improved compartment shower bath is both novel and simple, and is well adapted for the purposes set forth.
