FLUsHlNe-VALV'E.

SPECIFICATION forming' part of Letters Patent N o.. 694,107, dated February 25, 1902.

Application filed May 13, 1901.

To all whom, it may concern,.- A

Be it known that I, FREDERICK WILLIA MEYER, of Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Flushing-Valves; and I herebydeclare that the following is a full, clear, and exact description thereof, reference being had to the accom panying drawings, which form part of this specification. l

This invention is a flushing-val ve for sinks, water-closets, ttc., and is an improvement upon the valve shown in Patent No. 661,885, granted to me November 13, 1900; and the object of my present inventionis to provide a valve which will flush the closet, sink, te., at a desired pressure of water and will automatically regulate itself, so that it will not flush under higher pressures, but willrst reduce the pressure and then cause the flushing, vas hereinafter more fully explained.

The invention therefore consists in the l novel construction and combinations of parts, as set forth in the several claims herein, and the accompanying drawings illustrate the invention as applied to a Water-closet.

Figure l is a side view of the valve applied to a Water-closet bowl, showing the operative connection between seat and valve, Fig. 2 being an enlarged section through the com plete valve. i

The valve-casing is roughly of U shape, having an inlet-chamber A and an outletchamber B, connected by the flushing-chamber C.v The inlet-chamber A communicates with the service-pipe A at opening a and with the lower end of chamber C, but communication between chambers A and C being controlled or closed by a valve D, and communication between chambers B and C may loe closed by valve E on a stem F, extending through chamber B, as shown, and projecting into the closet-bowl XV. The casing is provided with suitable seats d e for valves D E, respectively, as shown, and said valves open in opposite directions and are arranged substantially as in my said patent, so that when one is open the other should be closed.

lFor this purpose the valve D is attached to an arm f, attached to the inner end of rod F within chamber C, substantially as shown in my said patent. To obtain an automatic Serial No. 60.075. (No model\ regulation of the liushing pressure, however, the valve E is not rigidly connected to stem F, but is of peculiar construction and controlled by a spring which can be adjusted so as to unseat the valveE at a predetermined pressure after valve D is' closed.

For thisv purpose the valve E is composed of a sleeve i E', loosely mounted on stem F and having a disk E2 attached to its inner end, and preferflow when headf is separated from the sleeve ,Y

by the inward movement of valve-stem F.

The chamber C has an outlet c above valve E,which communicates with a flushing or storing tank or reservoir (not shown) through a pipe C', as usual.

The inner end F2 of stein F is guided in a hole 7L in a screw-cap H, closing an opening in the casing directly opposite seat e and through which access can be had to valve E. The outer end of chamber A is closed by a similar screw-cap I, by removing which access can be had to valve D. These screwcaps facilitate assembling of parts and cleansing of thecasing.

Stem F projects into the closet-bowl and through an opening in the iiushing-rim w therein, the inner end ofA springK having a bearing against this rim w, a washer K' being interposed between the spring and flushing-rim to prevent water splashing through the opening of the rim. The inner end of rod F is hinged to the lower end of an oscillating lever L, fulcrumed on a stud tu', attached to the rim w, the upper end of this lever L carrying a friction-roller l, which is adapted to engage a cam m on the seat or set-hinge M, as indicated in the drawings. Spring K is powerful enough to normally hold the seat slightly raised and valve D closed; but when pressure is exerted on the seat, as in use, lever L is rocked, forcing rod F inward, opening valve D and closing valve E. Thereupon water ICO fiows through chambers A Cinto the liushing or storage tank (not shown) and accumulates therein under more or less pressure. Now when the seat is released the stem F is shifted inwardly by spring K, so as to close valveD and tension-spring G, which will exert itself to open valve E; but if the pressure of water in chamber C is such that spring G cannot overcome it the pressure is gradually reduced by the water escaping from chamber C into chamber B through the small passages in the sleeve E', as shown, these passages being ordinarily closed by the head f of an arm f; but when siem Fis initially moved back this head f is moved slightly away from thesleeve, allowing water to pass between the head f and disk to passage E5, and the water continues to escape through these passages until the pressure in chamber C is reduced suiiciently to enable spring G to unseat valve E, which it then does quickly, and the Water rushes out through chamber B, flushing the closet thoroughly. The spring G may be adjusted so as to elfect the unseating of valve E only at or below a certain pressure, and then if the pressure in chamber C is above the desired flushing-pressure valve E will not be opened until the pressure is reduced to the desired point. When rod F is again actuated so as to unseat valve D,it simultaneously positively closes valve E, so water will accumulate in the fiushing-tank as is desired.

Having thus described my invention, what I therefore claim as new, and desire toseeure by Letters Patent thereon, is-

1. The combination in a valve, of the casing, the chambers therein, the valve-stem,.the valve loosely mounted on said stem having minute water-passages therethrough, a head adjustably connected to the stem adapted to seat the valve and close the passages when the stem is moved in one direction, and a spring on said stem at the opposite side of the valve interposed between a collar on the stem and the valve, and adapted to unseat the' valve when the stem is moved inwardly and the waterfpress ure is suitably reduced all constructed and adapted to operate substantially as described.

2. In a valve, the combination of the casing having outlet and ilushing chambers, a valve forclosing comm unication between said cham bers, and a stem supporting said valve, said valve comprising asleeve loosely mounted on the stem, and having longitudinal water-passages extending through the valve; and a washer and disk on the sleeve; with a head on the stem adapted to forcibly seat the valve and close the said passages when the stem is moved outward, and a spring for unseating the valve when the pressure is suf'icientl y reduced, all constructed and adapted to operate substantially as and for the purpose described.

3. In a valve, the combination of the casing having outlet and flushing chambers, a valve through the valve; with a head on the stem4 adapted to forcibly seat the valve and close the said passages whenthe stem is moved outward, and a spring interposed between a collar on said stem and said valve, and adapted to unseat the valve when the pressure is sufficiently reduced, all constructed and arranged to operate substantially as and for the purpose described.

4. In a valve, the combination ot the inlet, outlet, and fiushing chambers, the oppositelydisposed valves closing communication between the storing-chamber and inlet and outlet chambers respectively, a valve-stem upon which the outlet-valve is slidingly mounted, and to which the inlet-valve is rigidly conneeted, and passages for escape of water past the outlet-valve; with means for operating said stem to open or close the inlet-valve, and to close the outlet-valve when inlet-valve is opened, and a spring adapted to unseat the outlet-valve at or below a certain pressure in the storage chamber, when the said inletvalve is closed, substantially as described.

5. In a valve, the combination of the inlet, outlet and flushing chambers, the oppositelydisposed valves closing communication .between said storing-chamberand inlet and outlet chambers respectively, a valve-stem upon which the outlet-valve is slidingly mounted, and to which the inlet-valve is rigidly connected, said outlet-valve having passages for escape of water therepast before it is unseated; wit-h means for operating said stem to open or close the inlet-valve, and to close the outlet-valve when the inlet-valve is open, and a spring on said stem adapted to unseat the outlet-valve at or below a certain pressure in the storage-chamber after the said inlet-valve is closed, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as myown I affix my signature in presence of two witnesses. l
