VALVE DEVICE.

SPECIFICATION forming part of Letters Patent No. 632,417, dated September 5, 1899.

Application filed March 27, 1897.

To all whom, it 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 following is a specification.

The object of my invention is to provide a valve device devoid of any weight or spring for operating it for use, primarily, as an automatic valve in connection with a watercloset to extend through the wall of the bowl and the flushing-rim therein with its stem projecting inside the bowl and afford means for controlling, through the medium of the seat, the supply of flush-water to a reservoir and the discharge from the latter into the bowl to flush it. My improvement is applicable, however, with more or less slight modification, to other purposes than that specified, such as to a stop and waste-valve; but inasmuch as I have particularly devised it for the water-closet use referred to the description thereof hereinafter contained is confined to that use, and it is shown in that connection in the acccompanying drawings, in which- Figure 1 is a partly broken and sectional view of a watercloset provided with my improvement; Fig. 2, a longitudinal sectional view of my improved valve device, showing the pist0n-valve in its position of opening communication between the reservoir and discharge and closing that between the supply and reservoir; and Fig. 3, a similar view of the same, showing the piston-valve in its other position of opening communication between the supply and reservoir and closing that between the reservoir and dis charge.

A is the valve-shell, formed, preferably, by way of affording convenience of access to its interior, as for repacking the valve, hereinafter described, in the three sections 1, r, and 7' illustrated.

The intermediate section 1' has shown as extending from its upper side the tube-section 12 of the flush-pipe B, leading from an outlet-port a; in the section to the overhead reservoir 0 and is provided on its lower side with an internally-threaded nipple q to receive a prop-rod q. At the opposite ends of the section 7, about which it is provided with Serial No. 629,597. (No model.)

the annular threaded flanges o and 0, are the internal annular shoulders n and m, against which respectively abut the packing-rings or gaskets n and m, formed, preferably, of leather.

The section r is threaded to engage with the threaded flange 0 and terminates in an annular internally-threaded head 1", afford ing the discharge-port x, into which is screwed the threaded end of the spud 1", having the side openings c o, the studs v at its inner end, and the central opening 1: in the head 11 at its outer end, and at the inner end of the section a" may be provided the annular shoulder n to cooperate with the shoulder '11. in clamping the gasket n.

The section r is shown in the form of a cap threaded to engage with the threaded flange 0, and may have an annular shoulder m at its inner end to cooperate with the shoulder m in clamping the gasket m, the cap being closed at its outer end and provided on its lower side with the nipple Z about the inletport 50 for connection with the water-supply pipe la, leading from the pressure-main. (Not shown.)

D is a tubular piston-valve closed at both ends and open through the wall or shell of its body portion, and from its inner end there extends the stem D, terminating in a socket,

in which is rotatably confined a hard-metal (as steel) antifriction-ball c'. The open condition of the tubular piston-valve D is shown to be afforded by numerous perforations it about the shell between its ends. It is immaterial, however, how this open condition is afiorded provided a su fficient portion of the shell near each end be imperforate, so that when the piston is in its forward position (shown in Fig. 2) only the imperforate portion at its outer end shall be exposed to the water-pressure supply through the cap 7' and the perforate portion shall be exposed to the passage through the tube 19 and to the discharge in the section 0", and that when the piston-valve is in its retracted position (shown in Fig. 3) only the imperforate portion of the inner end of its shell shall be exposed to the discharge and the perforate portion exposed to the supply through the cap and to the passage through the tube J. To afford these conditions, therefore, it is essential that the open portion of the tubular piston or portion thereof provided with openings shall, in the limits of play of the valve, be sufficiently extensive or that the openings shall be so disposed as to open the shell to the inlet-pipe l and the tube '1) in one position of the valve, and thus extend at opposite sides of the gasket m and short of the gasket 02 and to open the shell to the tube 13 and to the discharge in the section 7" in the other position of the Valve, with the perforate portion extended at opposite sides of the gasket'n and short of the gasket m to close the tubular valve to the inlet Z.

To apply my improved valve device into operative connection with a water-closet, the Wall of the closet-bowl F is provided, preferably at its'rear side, with an opening extending through both walls of the flushing-rim, about the outer end of which opening the end of the section 7" is pressed against an interposed gasket f, and the spud is inserted through the opening from within the bowl and screwed into the section r till the flange about the head 1: of the spud bears, with an interposed gasket f, against the inner surface of the bowl about said opening. The valve device may be propped from the floor by the rod q.

On the tube p, adjacent to its junction with the section r, I show hinged a plate g, having near its outer end a pendent finger g, to engageat its inner beveled side with the outer end of the stem D, for a purpose hereinafter described. The plate affords a bearing for the closet-seat E, fastened to it, so that the seat with its hinged plate-connectin g medium afiords a bent lever for automatically operating the valve, the operation of which is as follows: The normal position of the valve is that in which it is shown in Fig. 2, wherein the pressure behind it, from the inlet Z, tends to force the stem D against the finger g and thereby raise the seat. lVhen the seat is occupied or pressed .down, the engagement of the finger g with the ball-bearing end of the stem D forces the valve D inward to the position in which it is shown in Fig. 3, thereby bringing the perforations h short of the gasket 'n and to cross the gasket m and permitting the supply of water from the pipe Z to enter the tubular shell of the valve at the outer side of the gasket m and escape therefrom at the inner side of that gasket into the tube 19 and thence through the pipe B into the reservoir 0. On releasing the pressure upon the seat E the valve D need not immediately jump forward or shut off the supply to the reservoir, for the counter-pressure of the water passing through the valve and of that which has passed through it will tend to counteract or yieldingly obstruct the supplypressure behind the valve. Hence mere momentary pressure against the seat E to force the valve D back, as may be exerted after such use of the closet as requires the seat to be raised for it, will suffice to effect the supplyof a flushing charge through the valve from the inlet Z into the reservoir 0. By the release of the pressure against the seat the pressure behind the valve will more or less rapidly, according to the size or arrangement of the openings h, force it to the position in which it is shown in Fig. 1, in reaching which the stem D lifts the seat, and in which the flush-water may discharge from the reservoir into the valve-shell at the outer side of the gasket 02 and escape from the shell at the inner side of that gasket into the section 1", whence it enters the flushing-rim of the closetbowl F by way of the spud 7".

By the described sectional construction of my improved valve device the valve may be readily removed, as for repacking or otherwise repairing parts, either through the outer end of its chamber, on unscrewing the cap T or at the inner end thereof, from within the bowl F, on unscrewing and withdrawing the spud r Of course if the valve device is constructed for use as a stop and waste cock, while it would require the same ports in the same or substantially the same relations as those of the device adapted for the water-closet purpose described, other parts, including the valve-stem and spud, would be omitted, and the hinged plate for supporting the closetseat is not an essential feature even in connection with the water-closet use of the device. Instead of being hollow the pistonvalve may obviously be solid or fluted.

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

1. In a valve device, the combination with a valve-chamber having an inlet-port and a discharge-port respectively near its opposite ends and an intermediate outlet-port, of annular shoulders in said chamber flanking said outlet-port and provided with packing, a piston-valve reciprocably confined in said chamher to extend beyond said shoulders and having closed ends and being open between imperforate'end portions, said open portion exceedin g the distance between said shoulders, one of said closed ends being presented to the inlet-port to cause the valve to be normally impelled forwardly by fluid-pressure to bring the open portion of the valve at the outlet and discharge ports to open the latter and close the inlet-port, and means for retracting said valve against said pressure to bring said open portion at the outlet and inlet ports to open the latter and close the discharge-ports, substantially as described.

2.
