This invention is an improvement on my invention disclosed in my application for patent Serial No. 169,409 led October 6, 1937. The primary feature of the present invention is a mechanical combination which makes possible the use of a simple discharge control for the tub and the use of one opening, within the tub, both as an inlet and an outlet for the bathtub bathing water.
'I'hree major advantages result from this: One
1 is the absence of obstructive inlet devices like faucets. Two is the absence of the conventional hole and plug from the iloorwall in the tub. Three is the elimination of a complex mechanism which the conventional floor "pop-up valve requires. Four is the effect of a neater-job.
Other effects, advantages and purposes of this invention will become patent as the disclosure of it proceeds in the following detailed description, in connection with the accompanying drawn ings which,together with the text, are made a part of this specification, terminating inthe set of conventional claims.

In the drawings particularized:
55 The numeral It points to a bathtub as a whole,
which in general form-ation is like the conventional bathtub known to the art. It has a top portion, or rim, Ii confluent with upright walls I2 and I3 thereunder, which areintegral with. .o eachotheraswellaswith afloorwall Il embraced between them. At the Iiuncture of one of the lupright walls and the said embraced floor wall is embodied an opening I4, which is the opening serving the dual purpose of inlet and outlet.
The numeral 2l indicates a water-tight chamber, back of the bathtub, having an opening I4' which coincides with the opening I4 of the bathtub. The numeral 21 indicates a drain pipe,one side thereof extending from or joined to the bottom wall of the tub, and another side thereof extending from or joined to the said water-tight chamber. The said chamber and the said drain pipe are so connected to each other as to form therethrough a continuous leak-proof channel, which channel in one part thereof is in confluent relationship with the opening i4 communicating therewith.
'111e numeral 2l indicates a valve sleevea tube threaded externally, smooth internally-ntted into the drain pipe under a plane of the bathtub floor and at the juncture of the drainpipe and the chamber superimposed thereon. The numeral 24 indicates a plug or valve vfitting watertightly into the seat 2|, formed correspondingly within the valve sleeve 25. The numeral 2l indicatesastemextendingfromtheplug24toun arm 2l at the stem top. The arm 21|.-bifurcated, is a part of the combination more readily seen in the enlarged view thereof, in Figure 6, where -II indicates a control handle, il a pivot over Vwhich the arm operates.
The numeral 22 shows a pin through the`stem the bathtub by the valve or plug 24 in its seat 2l, the top of the chamber being watertightly closed.
An over supply of water in the tub flows out p through the overflow opening or openings near the rim like that shown by numeral l5.
But unlike that of my previously mentioned application the nal contents of the tub after a. bath are drained off, not through a hole in the floor wall, but through the same opening which admits the water into the tub. 'Ihis is made possiblel by raising the plug 24 or valve from and above its seat 26, whereupon a free passage into the drain pipe 21 is effected.
'Ihe numeral I6 indicates a grate situated back of, the opening-or within the opening I4' in Figures'h and9-thisdrainisprovidedtoprevent consequential solid substances from passing t out intcthe drain.
The numeral 38 indicates a housing with avpassage 29 therethrough. It is incorporated at the end of the tub, either on the sidesee Il" in Figures 12 and 13`-oi the watertight mixing chamber 28 or in theback of it-as shown in Figures 2 and 4-to receive the overiiow through openings l5 near the rim and direct the same to the drain pipe 21, for which pul'pOse the passage. ends at and extends into an opening therefor into the channel-of the drain pipe, at a plane preferably under the valve sleeve.
The numerals 32 and 33 indicatecontrol valves for the supply pipes, 3| shows a cross pipeleading from the supply pipes tothe faucet 35. whichis intended to supply drinking water for the bather or hot 'and cold water for iushing the tub. The numeral 39 indicates an enlarged part of the housing 38, which is provided where a plurality of openings i5 are embodied near the rim. While the numeral I6 indicates a grate or screened plate, the numeral i"indicates the openings in the said grate.
Sheet No. 2 of the herein incorporated drawings is included to show variations from the tlrst described form of by invention. Corresponding parts are indicated. by corresponding numbers. huch such numbers for convenience'of distinction are primed or double primed in the second sheet.
One variation therein disclosed is in the arrangement ofthe grate. In the second model the combination inlet and outlet embodies an integrated grate. In the -iirst model, the combination inlet and outlet, which is my preferred form thereof, is a wide graceful opening, protected by a grate situated back oi the said opening, rather invisible under ordinary observation.
Another variation disclosed is a frictional device for lthe valve control. The valve stem 23' operates through a tight channelin the disclosed model the channel/ls near the top. The
knob 5B surmounting the stem replaces the handie i8 of the control device shown in Figure 2. A further variation is shown in Figure il. Here a screw expedient replaces the frictional contacts of the control device shown in Figure d.
The numeral 5t in Figure il, corresponding to numeral 23 in Figure 8 is a valve stem. The
numeral 5l indicates a threaded part of the y stem, while the numeral 55 indicates a bushing internally screw threaded. and threaded correspondingly with the external threading on the stem at 5l. The stem operates through the bushing, thread for thread. The numeral 55 indicates ceptible to various changes and modifications.
the details here shown being merely for disclosure and not in limitation. The text herein is limited in description. The accompanying arrange drawings reveal' only unentais. VThe right is therefore reserved to make such adaptations, developments and expansion as properly fall within the scope and purpose suggested by these combined text and drawings disclosures, summarized conventionally in the appended claims.
