FLUSHING-VALVE.

Specification of Letters Patent.

Patented Aug. 29, 1916.

Application filed April 19, 1915. Serial N o. 22,412.

To all whom z't may concern:

Be it known that I, ALEXANDER FELEKI, subject of the Apostolic King of Hungary, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Flushing-Valves, of which the following is a specification.

This invention relates to ushing valves, and the object of the invention is to provide a simple and eiiicient device which will be noiseless in its operation and by the use of which the ordinary cistern or tank will be dispensed with.

The invention is illustrated in the accompanying drawings, and consists in certain novel features, which will be hereinafter irst fully described and then more particw larly pointed out in the claims following the detailed description.

In the drawings: Figure 1 is a sectional elevation of a flushing valve embodying my present improvements; Fig. 2 is a section on the line 2-2 of Fig. l; and Fig. 3 is an enlarged detail section of the regulating piston.

In carrying out my invention, I interpose between the supply pipe 1 and the flush pipe 2 a casting or coupling by which the said pipes will be directly connected. In the present drawings, this coupling is indicated by the reference numeral 3 and consists of a substantially cylindrical body having a branch 4 on one side which is coupled directly to the supply pipe 1 and having a branch 5 on the opposite sidein a higher plane than the branch 4 which is coupled to the flush pipe. In the present instance, the elements 2 and 5 are connected by an e1- bow 6.

The upper end of the Coupling 3 is closed by a cap 7 having a hollow central stem 8 rising therefrom to form a guide for the piston rod 9, and upon the upper extremity of the said stein or guide is a supplemental cap l0 by which the end of the guide 1s closed around the piston rod, as will -be readily understood. Said piston rod 9 extends axially through the casting 3 and has Secured thereto, at an intermediate point of its length, a valve disk 11 which is adapted to seat upon the annular partition 12 Within the casting immediately above the branch 4 which constitutes the inlet of the casting. This valve disk may, if desired, be covered with leather or other material to torni a packing between the valve and its seat, and 1t will'be readily understood that, when the valve 1s closed or seated, the flow through the coupling or casting 3 will becut off and, if the valve be raised or opened, the iiow through the coupling will be permitted.

The lower portion of the casting or coupling 3 is reduced in diameter, as shown at 13, and the lower extremity of this reduced portion is closed by a cap 111. Upon the lower extremity of the piston rod 9 is mounted a regulating piston which is adapted to retard the descent of the piston rod with its attached valve 11 and thereby efect a noiseless seating of the valve. This regulating piston consists, in the arrangement illustrated, of a' disk 15 secured upon the piston rod 9 at a point somewhat above the lower extremity of the same, and of a diameter slightly less than the bore of the reducedv portion 13 of the coupling. This disk 15 constitutes a stop or fixed abutment for the flexible washer or cup piston 16 which is itted around the lower portion of the piston rod and against the said disk and is clamped to the said disk by a metallic or' other rigid washer 17 and a nut 18 mounted on the piston rod and bearing against the said washer, as clearly shown in Figs. 1 and 3. It will be readily understood that upon the upward movement of the piston rod, the piston 16 will yield to theforce of fluid above the disk 15 so that the fluid may flow around the piston into the lower end ,of the cylinder or coupling. On the return movement of the piston rod, the pressure of the fluid below the piston will cause the same to expand against the walls of the cylinder and, consequently, the descent of the several parts will be resisted so that the seating of the valve will be retarded and v will, consequently, be effected quietly.

It is, of course, obvious that the fluid below the piston must be permitted to escape or otherwise the piston and the valve would be held permanently in a raised position. In the present instance, I provide a vent passage 19 which opens at its lower end through the lower end of the piston rod and at its upper end through the side of the rod above the piston, as shown most clearly in Fig. 3. In the lower end of the vent, I mount a regulating screw 20 which has a tapered groove in one side and may be set in or out so as to regulate the eiective diameter ot the vent or entirely close the same and thereby easily and eiectually regulate the ventingflow.

The upper end of the piston rod 9 is rigid with a vertically disposed rack bar 2l which bears against and is guided by flanged rollers 22 disposed above the cylinder, and this rack bar is engaged and operated by a segmental gear 23. The said segmental gear is formed upon or secured rigidly to an operating lever 24 which is fulcrumed at one side.

mounted, and the coupling or cylinder 3V may be secured to the said plate by means of screws or bolts inserted through the lugs or ears 30 formed on the cylinder. AA covering or inclosing case 31 may be fitted over the working parts, and this cover will be provided with a slot 32 to accommodate the operating lever and will be preferably lined with felt or some similar material, as indicated at 33, so as to protect the working parts against variations in temperature.

It is thought the operation of my device will be readily understood from the foregoing description taken in connection with the accompanying drawings. When it is desired to permit the flow through the iiushing pipe, a pull is exerted upon thejchain 25 which will serve to raise the inner end of the lever 24 against the ,influence of the weight 26. This movement of the lever will, of course, impart movement to the segmental gear 23 which in turn will exert a lifting action upon the rack bar 21 so that the piston rod with the valve 11 and the regulating piston attached thereto will be raised, the valve 1l leaving its seat and thereby permitting flow through the coupling or cylind e'r`3 from the supply pipe l and the inlet 4, past the valve seat, and thence out through the branch or outlet 5 into the flush pipe. The iow may be continued, of course, as long as the holding force is exerted upon the chain 25, but the instant the said chain is released, the weight 26 will descend by gravity and cause a return movement of the parts which will bring the valve 11 toward its seat. During the iiushing operation, some liquid will have accumulated below the regulating piston and, when the descending movement of the piston begins, this liquid willbe subjected to some pressure which will react upon the piston and the valve to re- 'the valve 11, and that the inal seating of the valve will be eiected noiselessly.

It will be readily noted that the apparatus is composed of very few parts which are simple in their construction, compact in their arrangement and are easily operated and also readily accessible should it become necessary through accident or otherwise to make repairs.

Having thus described the invention, what is claimed as new is 1. In a device for the purpose set forth, thecombination of a casing provided with an inlet and an outlet and an internal valve seat between the inlet and the outlet, the lower portion of said casing being reduced, a piston rod disposed axially in the casing and extending through the upper end thereof, a valve on said rod adapted to engage said valve seat, a retarding'piston on the lower end of said rod playing in the reduced lower portion of the casing, a rack bar rigid with the upper end of the piston rod, a lever fulcrumed intermediate its ends at one side of the piston rod, and a segmental gear meshing with the rack bar and fixed to the lever with its pivot concentric with the fulcrum of the lever, the lever extending beyond the rack bar and being provided at its inner end with a counterbalance and at its outer end with an operating medium.

2. In a device for the purpose set forth, the combination of a wall plate, a casing secured thereto and having an inlet and an outlet, a piston rod disposed within the casing and extending through the upper end thereof, a valve carried by said rod and seating within the casing between the inlet and the outlet, a retarding piston carried by the lower end of said rod and playing in the lower end of the casing, a bracket secured to the wall plate above the casing, a lever fulcrumed upon said bracket and extending past the piston rod, a gear pivoted upon said bracket coincident with the fulcrurn of the lever and movable with the lever, and operative connections between said gear and the piston rod.

In testimony whereof I aiix my signature in presence of two witnesses.
