NON-FREEZING WATER-CLOSET.

Specification of Letters Patent."

Patented Aug. 15, 1916.

Application filed August 14, 1914. Serial No. 856,714.

To all whom it may concern.-

Be it known that I, GEORGE W. BUMGAR- NER, a citizen of the United States, and resident of Baltimore, Maryland, have invented certain Improvements in Non-Freezing Water-Closets, of which the following is a specification.

In the description of the said invention which follows, reference is made to the accompanying drawings forming a part hereof, and in which Figure 1 is a central sectional view of such parts of the improved closet as are involved in the present invention; and Fig. 2 a plan of the same. Fig. 3 is a View illustrating an alternate construction of parts of the apparatus.

Referring now to Figs. 1 and 2 of the drawings, 1 is a part of the bowl of the closet, and 2 a shell having a branch 3 which connects it to the bowl.

4 is a pipe leading from the shell 2 to the flushing tank which, as it forms no part of the present invention, is not shown.

6 is the main water supply pipe extending downward from the shell 2, to the valve chamber 7 the bottom of which is adapted for attachment to the service water pipe not shown.

A portion of the valve chamber 7 is accurately bored to produce the cylinder a, and is provided with a by-pass 10.

Between the openings 6 which connect the by-pass 10 with the interior of the cylinder a, is a piston 12, and extending from the lower end of the piston and integral therewith, is a stem 13 the part d of which is square in cross-section. The remaining part 6, of the stem 13 may be cylindrical, and to its end is secured the conical valve 14 which is formed of vulcanized fiber.

The seat 15 for the valve 14 is formed at the lower end of a square sleeve 16 and is screwed into the valve chamber. The interior of the sleeve 16 is considerably larger than the part c of the stem, in order that water can pass around it from the service pipe, not shown, to the by-pass when the valve 14 is open or in its lowest position as shown in Fig. 1 of the drawings. The sleeve 16 which surrounds the stem as before stated, is square, and should the piston 12 be turned by means of the rod 17, the sleeve also will be turned and its threaded end screwed into the valve chamber, or unscrewed from it; and in the latter case,

admit of the piston and the conical valve 14 being withdrawn from the chamber.

It will be understood that, due to the part cl of the stem 13 being polygonal and loose within the sleeve as described, that in turning the piston to screw or unscrew the seat 15 in the valve chamber 7, the vertical position of the piston is not changed.

Ports 9 provide for the passage of water from the sleeve 13 to the by-pass 10 and to both ends of the piston 12 which are therefore subjected to a common water pressure.

17 is a rod screwed tightly into the piston 12 and extending upward through a suitable packing box 19 at the top of the shell 2.

20 is a valve fastened to the rod 17, which when the valve 14 is unseated bears tightly on the seat 22.

24 is a branched rocker pivoted at h to a lug 27 formed as a part of the shell 2. One end of the rocker serves as the support for the closet seat 30, and the other end carries the weights 32 which overbalance the seat when the same is unoccupied. The rocker is also provided with inwardly extending pins 33 which as the seat is depressed bear upon the disk 34 and force the rod 17 and the parts connected thereto to their lowest position as shown in Fig. 1, when water from the service pipe passes to the closed flushing tank before referred to.

When the seat is released the pressure of water acting on the valve 14, closes the said valve, and opens the valve 22 thereby admitting water from the flushing tank to the bowl 1, and the flushing operation continues until the tank is practically empty, and the said tank is not filled until the seat is again occupied for a period.

To insure the upward movement of the rod 17 and its atachments, independently of the water pressure, the underside of the branched rocker is provided with the arms 35 which as the seat rises bear against the underside of the disk 34 and thereby cause its elevation.

37 is a small aperture in a nozzle projecting from the valve chamber 7, which is uncovered when the piston 12 is in its highest position. Its function is to drain the cylinder below the piston of its contained water and thereby-insure the operation of the apparatus in freezing weather.

In Fig. 3 the apparatus corresponds with that above described, except that a coiled spring 39 one end of which bears against the underside of the disk 3% and its other end passes through a hole in the lug 27 is substituted for the weights 32.

I claim as my invention 1- 1. In a water closet apparatus, a bowl, a shell which is open to the bowl and provided with a nozzle leading to a flushing tank, an annular valve seat and a valve therefor in the shell situated above the said nozzle, a valve chamber adapted for the admission thereto of service water, the same having a drain aperture; an annular detachable service water valve seat which is screwed into the valve chamber, the same being provided with an upwardly extending sleeve of poly onal cross-section, a piston in the chamber to control the drain aperture, and an upwardly closing service water valve having astem which connects it with the piston, the portion of the said stem which is within the polygonal sleeve being polygonal in order that in its rotation it willscrew or-unscrew the valve seat' into or from the chamber, combined with a rod which unites the piston with the valve in the shell, and serves for turning the same, substantially as, and for the purpose specified.

In a water closet apparatus, flushing mechanism including a pipe, a water supply in communication with one end thereof, a valve stem, an upwardly closing valve mounted thereon and controlling said water supply, a bushing furnishing a seat for said valve and threaded in said pipe, a bowl and a reservoir, 21 second valve on said stem for governing the bowl connection, and means on said stem and for engagement with said bushing to unscrew the latter.
