To all whom it may conw'm:

Be it known that we, .l'L'Lius D. Tstuorln and llntsox G. Gounau, citizens of the Unitcd States, residing at New Orleans, in the parish of Orlea us and State of Louisiana have invented new and useful improvements in Flushing .Dwiccs, of which the following is specification.

Our invention relates to flushing devices for water closets, and its object is to simplify and improve the construction of devices of this kind.

In its preferable form the invention is embodied in the device set forth in the following description and accompanying drawings.

In the drawings: the ligurc shown is a centralvertical section of the device.

Referring to the drawings A is the body 01' the valve casingv it has an inlet opening B and an outlet pipe l C, the latter leading to the bowl.

Mounted on the pipe C is an operating lever D having an arm it mounted within the pipe and adapted to bear against a stem F to which is secured a pilot valve G. The pilot valve is held yieldingly on its seat by a coiled spring H surrounding the upper part or stud l of the valve stem. The upper end oi the coiled spring surrounds a dmvnwardly projecting stud .l which is provided with a. threaded head vli engaging screw threads on the interior of a main flushing valve L. The screw stud J serves as means to adjust the tension of spring ii.

The pilot-valve G is adapted to close and open port G which serves to establish communication between the interior of the main valve and the outlet pipe C.

The flushing valve is provided at its lower end with a rubber or leather washer M adapted to seat on the valve casing, and the valve is adapted to control the communication between the inlet B and the outlet pipe C. Secured to the valve L is a skeleton cage N which moves in the pipe (l and serves as a guide for the valve Land also to guide the valve stem F.

Clampcd in the upper end olihe valve L, by a threaded wash r O is a flexible diaphragm P, preforably ol' rubber. which is clamped around its'cdge to the casing by screws Q passing through the annular flange oi an int-losing cap or cover B. An air and water chamber S is formed Ly and between this cap and the diaphragm. 'lhis chamber communicates with the iutrja'ior of the valve L by holes or passage ways T iormcd in th screw-stud J. In thecap It is a screw trap U for permitting ready access to the chamber S. Depending from this trap is an adjustable stopscrew V, adapted to limit lheupw'ard movement of the diaphragm and which may be adjusted to regulate the extent of said movement.

The chamber S communicates with the inlet ll by a small pipe or passage way W, in which is mounted a regulating valve X, consisting of a screw extending against the beveled. seat Y in the pipe or passage way \l, the upper end of the pipe or passage way, Which is extended into the cap It, being provided with a closing screw Z.

The operation of the devi e is as follows: Upon raising the lever D and arm 1f, the valve stem F will be raised and the valve G raised from its seat in the main valve L. Therenpon the water will be permitted to escape from within the main valve and from the chamber S into the outlet pipe C. This escape of the water will relieve the pressure in the chamber S on th e diaphragm, and the latter will be raised by the pressure of the water from the inlet, carrying up with it the main flushing valve L which thereby establishes communication between the inlet B and the outlet G and the water rushes into the bowl. At the same line water from the inlet will pass in a comparatively small quantity through the passage way W into the chamber S. The flushing valve L will remain open and the flushing action be continued until the chamber S is filled with the incoming air and water and the diaphragm forced out and down so as to seat the valve L and close communication between the inlet and outlet. The length of the flushing may be regulated by the adjustment of the screw X, which may be screwed down or up to lessen or increase the size of the passage and thus regulate the flow of the water passing into the chamber and consequently the length of time of the flushing action.

The inlet B may be connected either to a tank or directly to a water main.

It is clear that various changes in the details of the device may-be made without departing from the principle of our invention.

Having thus described our invention, what we claim 1. The combination of a substantially cylindrical casing, a discharge pipe lending substantially centrally from the bottom of the casing, a main valve seat at the top of said discharge pipe, a hollow main valveresting; on said seat, a diaphragm secured to the top of said main valve, 21 cover securing the diaphragm to the using, a guide cage reciprocablc. within the discharge pipe and connected to the main valve for directing its movement, a pilot. valve seat within the main valve, a pilot valve resting on said seat and having; a stem passing through and to a point below the guide cage, :1 spring resting upon the pilot valve, and an adjusting screw near the top of the hollow main valve forming an abutment for the spring and providing means of adjustment for the same.

2. The combination of a substantially cylindrical casing,

a discharge pipe leading suhstantialv centrally from the bottom of the cosine a main valve seat at the top of said ischarge pipe, a hollow main valve resting on said seat, a diaphragm secured to the top of said main valve. a cover securing the diaphragm to the casing", a guide cage reciprocable within the discharge pipe and connected to the main valve for directing its movement, a pilot valve seat within the main valve, a pilot valve resting on said seat and havin; a stem passing through and to a point below the guide 2 l p evaaav cage, a spring resting upon the pilot valve, an adjusting screw near'the top of the hollow main valve forming an abutment for the spring and constituting means of adjustment for the same, and a screw trap in the cover removable to permit adjustment of the spring.

3. Thecombination of a valve casing, a discharge pipe, an inlet pipe, a hollow main valve within the casing, a guide cage therefor movable in the discharge pipe, a diaphragm connected to the main valve, and dividing the casing into an upper and a lower part, a by-paas leading fromthe inlet to the upper part of the casing, a pilot valve within the hollow main valve, a spring holding the pilot valve normally on its seat, a perforated screw memher in the main valve, serving as an abutment for the,

spring, as adjusting means therefor, and permitting fluid to pass from the upper part of 'the casing to the lnterion of the main valve, and a stem on-the pilot valve extending through the guide and below the guide cage, and a finger actuated from outside the casing and adapted to raise the stem ofthe pilot valve. 1

'4. The combination of a casing, a hollow main valve therein' and free from the-casing, a diaphragm connected to said valve and the casing, a tubular member communieating with the casing, a guide cage movable in said tubular member and connected to the main valve serving to guide said vgllve, an auxiliary valve within the main valve,

a spring forclosing the auxiliary valve, and a perforated abutment carried in the bore of the main valve serving to hold the spring against the auxiliary valve.

ti. The combination of a casing, a hollow main valve therein and free from the casing, a diaphragm connected to said valve and casing, a tubular member communicating with the casing, a guide cage movable in said tubular member and connected to the main valve serving to guide said valve, an auxiliary valve within the main valve, a spring for closing said main valve, and an abutment for the spring adjustable in the main valve for regulating the action of the spring. I

6. The combination of a casing, a tubular member communicating with the casing, a main valve seat thereon, a hollow main valve within and free from the casing and seating on said main valve seat, a. guide cage connected to the main valve and movable within the tubular member,

an auxiliary valve seat within the main valve, an auxlliary valve seating thereon, a spring tending to set the auxiliary valve, and an abutment adjustable within the main valve for regulating the pressure of the spring.

7: In devices of the character described, the combination, of a hollow main valve, a valve seat therein, an auxiliary valve normally resting on the seat, a spring urging the auxiliary valve to normal position, and an abutment for the spring adjustably mounted in the main valve.

In testimony whereof we have hereunto afiixed our signatures.
