VALVE DEVICE.

SPECIFICATION forming part of Letters 'Patent No. 505,272, dated September 19, 1893.

Serial No. 469.470. (No model.)

To @ZZ whom t may concern:

Be it known that I, JOHN KELLY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Valve Devices, of which the followingis a specification.

The object of my invention is to provide for usein the overhead Siphon-operated flushing-tank of a water-closet a construction of valve-device whereby it shall be adapted to operate automatically to graduate the liow of the liquid it controls until the iiow is, finally, shut oif altogether.

In the accompanying drawings, Figure 1 is a broken view in sectional elevation of the overhead flushing-tank of a Siphon-closet provided with my improved valve-device. Fig.

2 is a vertical section, enlarged over the scale in Figi, of the Valve-device involving the saine construct-ion as that presented in the first View. Fig. 3 is a section taken at the line 3 on Fig. 2 and viewed in the direction of the arrow.

Adenotes an overhead water-closet tank containing a siphoning device B of any desired construction, that shown involving the flush-pipe r having a branch q and covered by the cap p; a valve o being seated on the branch q and connected with a lever fn, operated by the usual depending chain n. The siphon operates in the well-known manner: namely, by raising the valve o, it draws the water of the tank through the cap p down the pipe r till the water-supply in the tank falls below the entrance between the cap and flush-pipe, when air is admitted and breaks the siphon.

Ois my improved valve-device fitted over the water-supply pipe m, which, as shown,

leads through the base of the tank, whereinV it, (or the coupling connecting itwith the tank, as the connection is represented in Figs. l and 2) terminates in an internally threaded cup m into which is screwed the lower end of a hood Z, which contines an annular diaphragm or washer 7c, preferably of leather or rubber, seated in the cup. A tube 'L' extends through the annular washer at one end into the hoodZ and at its other end into the supply-pipe m and is pivotally supported at its head-portion, which is closed, on the inner end of the rod of a float D, the rod being fulcrurned at x in the outlet-opening h of the hood, forming the discharge-opening from the valve-device into the tank. In the lower end .of the tube t' is a minute opening and between the ends of the tube are the two openings 112 and t3, the latter being shown the larger of the two. These openings i2 and i3 may be in one side or in different sides of the tube, or they may be in each side thereof, and there may be more of them than the two; and, if desired, instead of providing a number of the openings, one elongated opening will answer, as will be apparent from the description, hereinafter contained, of the operation.

As described, the device operates as follows: While the tank A contains its supply of water, the iioat D is ioated at the position in which it is represented in Fig. l, wherein the tube ft' is so far protruded downward through the annular diaphragm lo, that both openings t2 and t3 are below the plane thereof. In this position of the tube, while water from the pipe m may enter it through all the openings t', 2 and t3, none can enter the hood Z and thence discharge through the outlet h, into the tank, since the diaphragm prevents. On operating the siphouB, however, which withdraws the water from the tank, the float sinks with the level of the water, thereby raising the tube t' till its opening i3 reaches above the plane o f the diaphragm 7s, when the water, which enters the tube from the pipe m, can escape into the hood Zand thence discharge into the tank. This supply through the tube i obviously increases, till the tube has been so far raised, by the falling of the ioat to a low position, as to bring both openings 2 and i3 above the washer. Then, the only supply being through the minute opening t', it is too little to keep the water-level in the tank above the entrance to the siphon, which eventually ceases to operate by air entering it. Then the tank begins to refill, and as the level of water rises in it, the iioat D is tube below the plane of the diaphragm, whereby the feed-water enters the tube through both openings t" and ft2, and discharges through the opening i? into the tank. Thus the feed is increased till the supply in the raised, thereby lowering the opening t2 of the IOO tank becomes sufficient to have raised the iioat so high that it has lowered the tube 'L' far enough to pass the opening 3 across the plane of the diaphragm k, during which passage, obviously, the flow of the feed water is diminished till it is eventually shut off altogether by the opening i3 passing the plane of the diaphragm.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a valve-device, the combination with the supply-pipe to a flushing' tank A containing a siphoning device B, of a hood Z, a diaphragm lo covering the lower end of the hood, a tube z supported to extend through the diaphragm with one end in the hood and the other end presented to the supply-pipe, the hood and tube being adapted to be recipro- .cated one with relation to the other, an openlng inthe tube between its ends, and an opening t" in the end of the tube presented to the supply-pipe, substantially as and for the purpose set forth.

2. A valve-device comprising, in combination with the supply-pipe to a iiushing-tank A containing a siphoning-device B, a diaphragm 7c on a seat m' in said supply-pipe, a hood Z confining the diaphragm on its seat and provided with a lateral discharge-opening h, a reciprocating tube 'i supported to extend through the diaphragm with one end in the hood and the other end in the supply-pipe, an opening z" in the lower end of the tube and an opening in the tube between its ends,

and a float D on a rod fulerumed in the open-v ing h, and fastened at its inner end to the tube, substantially as and for the purpose set forth.
