Patented Sept. 6, 1932 i a UNITED STATES ALFRED ROSEWOOD, or SAN FRANCISCO, CALIFORNIA wAsrE AND oviinrnow FIXTURE FORBATH r ms Application filed August 10, 1928. Serial No. 298,824.
The invention relates to improvements in waste and overflow fixture especially adapted to bathtubs in which the bathtub plug or stopper is 'forced from its seat by other means "a than the customary chain-pulling method.
Theobjects ofthe improvement are: First: To discourage that improper condition of installation of the waste fixture where the stopper is located in the T in line with the overflow pipe, and therefore permit a considerable distance of unclean surface to be directly churned and washed by the water which the bather imagines is free fromany munlcate with 1ts central bore 15 radially septic contact.
Second: To afl'ord facilities to automatically spray this rather unclean and forgotten portion of the waste fixture, and
. Third: To lift the stopper from its seat by the pressure of the water in the supply water-l I pipe, by merely pressing a knob that opens a valve at the overflow fixture. It can be placed at any convenient place. v
Several forms of the invention are illustrated in the accompanying drawings in 1 which Figure 1 shows a vertical section of the entire outlet and overflow fixture connected to a bathtub.
Figure 2 is a plan view of the ture with the stopper removed; 7
Figure 3 shows a verticalsection taken on line 33 of Figure 1; p 4

Fi ure 5, a section of the outlet fixture showing a slightly modified form for keeping the stopper from reseating;
Figure 6, a View similar to Figure 1, showing a modified form of outlet fixture; 40 Figure 7, a plan view of the outlet fixture shown in Figure6; and I v I Figure 8, a vertical section through another modified form of outlet fixture.
Fig. 1 shows the overflow pipe 4 broken away at one endand 5 is the waste outlet fixture. At 6 is shown the outlet in crosssectionof the tub, and at 7 the overflow fixture. The overflow fixture is provided with a lug 8 which retains a special valve 9 screwed in from the inside and provides for connection with the supply water pipe. The valve has a metallic washer 10 seated on a gasket 12 and is opened by pressing on the knob 14; the stem of which is reduced in crosssection-at 13 and carries spring-13 reacting on the valve body and the larger section of the stem. The valve body is provided with a groove or recess 15 and'holes 15 that comor otherwise. 1
Facing the lug 8 and encircling the valve body at its circular groove is an annular flattened ring 17 having a projecting nipple 18 to which a tubing 19 is soldered so as to communicate with the said groove. The relatively long cylindrical body of the valve serves as a means-ofholding the overflow'fiy ture to the .bathtub'perforation by'the nut 22 screwed on it against the overflow plate 21 which can be made in any fancy design. The
Sinceit only takes a slight pressure on the valve knob 14 to dislodge the submerged stopper 39 of the full bathtub, provision is made to prevent the piston from returning and the plug r-eseating under the pressure of the bath water. A hole 30 is drilled in the upper piston 26 and a suitable tumbler 31 acts therein against a spring 31 so when the piston rises the rounded end of the tumbler 31 catches on the edge of the cylinder 26 at 31 and holds it there. While the pressure of the water is not suflicient to force the tumbler back for reseating the stopper, replacing of the stopper by hand may easily overcome'the resistance of the spring.
The cylinder 26 performs an additional function by holding the upper and the" lower members of the waste fixture fittings to the bathtub supplemented by two screws 25 enter-- ing lugs 23 in the lower fitting .ofthe fixture. See Fig. 3. The cylinder26 is provided with a screw-driver slot 27 on the flange which rests on an annular rib 44 which is integral with the upper fitting with its concentric seat for the stopper. The lower piston disk 46 is pressed on the piston rod and is provided with a recess for packing materials 46. The small quantity of water used by the cylinder is returned to the valve and finds its way out through a slot or hole 45 in the valveand is automatically closed when the valve is opened. See Fig. 1.
' A U shaped flat spring 32 may be secured to the plug 39 to prevent it from reseating as shown in Fig. 5. The plug may be conveniently fastened to the cylinder by means of .U
It is also evident that the plug can be lifted from its concentric seat by a water 'jet .of sufficient volume and velocity reacting on a lever of correct design. Figures6 and 7 show such construction.
i In this form, the pipe 19 terminates in a nozzle 35 on which rests the lever 36, hinged between two lugs 37 in the lower fitting which lever communicates its motion to the stem 38 and the stopper 39.
To prevent the stem 38 from returning a rounded groove 40 is provided on it to engage a tumbler 41 housed in one of the stays 41 which supports the hub 43 in which the stem 38 is guided. I This stay is formed integral with the upper fitting of the waste fixture.
. A spring 42 forces the tumbler into. the groove when the stem is raised and holds the overflow and waste fittings. I, therefore, do not claim such mechanical movements, but I claim: o 1. In a fixture of the character described having a discharge port, a stopper for closing the same and an overflow port, pressureoperated means for removing the stopper from its seat anda manual control mounted .in the overflow port for the pressure means.
3. In a bathtub having a discharge port,
a stopper for the same, an overflow port and a sewer pipe connectingwith both ports, pressure-operated means forv removing the stop per from its seat, and a control means for the same comprising a conduit mounted in the sewer pipe in alinement with the overflow port, a valve housing threaded thereinto having a central bore, radial ports connecting therewith, an annular groove connecting with the radial ports, a ring surrounding the groove having. a nipple communicating with the groove, a conduitleading from the nipple to the stopper actuating means and a valve for the housing having an operating stem. ex-
tending through the overflow port.
. 4. In a fixture of the character described having a discharge port and a. stopper for closing the same, pressure-operated means for removing the stopper from its seat, the said means comprising a cylinder mounted underneath the stopper,lmeans for admitting a pressure medium thereinto from below, a piston movable in said cylinder having a plunger associated therewith for ejecting the stopper when the pistonis raised and a port in the cylinder adapted to be uncovered by the risingpiston for allowing the pressure medium to escape therethrough for spraying and cleansing the region below thestopper.
5. In a fixture of. thecharacterdescribe'd having a'discharge port and a stopper for closing the same, pressure-operated means for removing the stopper from its seat, the said means comprising a cylinder mountedunderneath the stopper, means for admitting a pressure medium therein'to from below, a piston movable in said cylinder having a" plunger associated therewith for ejecting the stopper when the piston is raised and a port in the cylinder adapted to be uncovered by the rising piston for allowing the pressure medium to escape therethrough for spraying and cleansing the region below the stopper, the plun er having means associated therewith for yie dingly holding the plunger in stopper ejecting position.
In testimony whereof, I have hereunto set my hand at San Francisco, California, this sixth day of August, 1928. V
ALFRED ROSEWOOD.
