Serial No. 436,048. I

To all 'whom it may concern:

Be it known that I, HARRY W. VARD, a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in IVatenClosets; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to water closets and more particularly to that class of closets adapted for use in exposed places where there is liability of the freezing of the water if stored to flush the closet, as in the ordinary house closet.

The obj ect of my invention is to provide a closet of this character in which a temporary storage reservoir is i'illed while the closet is in use and the hopper flushed automatically as the person rises from the seat by the water stored temporarily in said reservoir, so that when the closet is not in use the reservoir and connections are all thoroughly drained to prevent freezing at any point above the frost line.

To these ends my invention comprises, generally stated, a hopper, a supply pipe, a reservoir, connections between said supply pipe and said reservoir and between said reservoir and said hopper, a valve controlling the supply from said supply pipe, means for operating said valve automatically, and a gravity-valve in the path of the fluid admitted by said supply pipe and adapted to cut olf communication to said hopper, said gravity valve when not in use being below the frost-line.

In the drawings Figure 1 is a sectional elevation of my improved closet; Fig. 2 is a like view showing the position of the parts when the closet is occupied; Fig. 3 is an enlarged detail of the gravity valve; and Fig. 4 is a perspective view of the seat-hinge.

By reference to the drawings the numeral 2 designates the fioor which supports the hopper 3 secured thereto. A soil pipe 4 is connected up to the hopper 3 in the ordinary manner. A seat 5 is fulcrumed at 6 in the hopper 3. The arms 7 on the seat 5 are connected to the upper end of the rod 8 by pin 8a, said rod extending down into the pipe 9. The upper end of rod 8 is forked. At the upper end of the pipe 9 is the collar 10 and a threaded nipple 11 engages a threaded seat in said collar. The rod 8 passes through the nipple 11 and said rod is connected to the supplemental rod 12 by the connecting nut 13. A spring 14 is interposed between the nut 13 and the nipple 11 and said spring acts to hold the seat normally in its raised position.

Secured to the lower end of the pipe 9 is the casting 15. A valve 16 on the stem 12 controls the supply port 17. This valve may be of any suitable construction, that shown comprising the cup-leather 18 and the washer 19. The washer 19 rests normally on the shoulder or seat 20. The supply pipe 21 is connected to the supply-port 17.

A coupling 22 connects the outlet 23 with the pip'e 24. At the lower end of the pipe 24 is the gravity-valve 25 which normally rests on the stop 26. The stop 26 which supports the valve 25 is located below the frostline so that the valve will not freeze to the said stop and be prevented from rising when it is desired to lift said valve and seat it on the valve-seat 27 The valve 25 is not of sufficient size to entirely close the pipe 24, as clearly indicated, so that any fluid in the pipe 24 can find its way to the drain. rThe upper end of the valve 25 is conical in shape and when said valve is elevated in the pipe 24 it will be guided and seated in the valve seat 27 at one end of the passage 28 which leads to the hopper 3. A connection 29 is connected by the collar 30 to the pipe 24. This connection 29 has the by-pass 31 to receive the pipe 28a. There is a passage 32 be tween the end of the by-pass 31 and the inner wall of the connection 29 which permits the passage of fluid to the pipe 33 connected to the reservoir or tank 34. The drain outlet 35 has the seat 36 controlled by the valve 37 on the stem 38 at the lower end of the rod 8. A- coupling 39 connects the drain 35 with the drain pipe 40. The drain pipe 40 leads into the soil pipe 4.

l/Vhen my improved closet is in use and the seat is depressed by the weight of the occupa-nt the rod 8 will be raised, compressing the spring 14. This movement of the rod 8' raises the valve 16 and the uid passes from the supply pipe 21 to the outlet 23 whence it passes to the pipe 24. The pressure of the fluid so admitted will elevate the gravity valve 25 and move said valve up until it reaches the seat 27. The pressure of the fluid will act to hold the valve securely to its seat and cut off the flow of water to the hopper. The fluid passes the valve 25 and enters the reservoir 34. As long as the seat 5 is depressed the water continues to flow to the reservoir. It should be stated that the elevation of the rod 8 also lifts the drainvalve 37 to shut off the drain and prevent the escape of the fluid admitted to pipe 24. lVhen the occupant rises from the seat the action of the spring la lowers the rod 8 and liftsl the seat to the position shown in Fig. l. The valve 1G is immediately lowered and the supply cut off, While the drain is opened. lVlien the pressure which holds the valve 25 to its seat is relieved said valve will descend of its own weight until it rests on the stop 2G. This opens communication from the tank 34 by the pipes 33, 24 and 28 to the hopper and the water rushes into and flushes said hopper. The column of water cont-ained in the reservoir and pipe 24C gives sufficient volume to thoroughly flush the hopper only a small portion escaping through the drain. When the hopper has been flushed in this manner any water .remaining in the tank or the pipes is drained off' so that thereA is no liability of freezing or the difficulties which arise therefrom. By having the valve 25 below the frost-line there is no danger of said valve freezing to the stop 26, but it is always free to be lifted by the flow of water to the tank.

The construction is simple and composed of few parts so that there is little liability of its getting out of order, and if it should do so the parts are readily accessible and the valves quickly removed for purposes of repair.
