WATER-CLOSET VALVE.

SPECIFICATION forming part of Letters Patent No. 247,789, dated October 4, 1881.

-Application filed December 27, 1880.

To all whom it may concern:

Be it known that I, PETER WHi'rE,of St. Louis, Missouri, have made a new and useful Improvementin lVater-OlosetValves, of which the following is a full, clear, and exact description, reference being had to the annexed drawings, making part of this specification, in which- Figure l is a vertical longitudinal section taken through the improved valve; Fig. 2, a longitudinal section taken at right angles to that of Fig. l, and looking in the direction indicated by the arrow of Fig. 1. The valve is shown closed. Fig.3 is a longitudinal section, upon an enlarged scale, of the upper portion of the movable parts of the valvefthe view being in the same direction as that of Fig. 1, and the valve being opened; Fig. 4, a longitudinal section of the parts shown in Fig. 3, but at right angles to the view of Fig. 3, and showing the valve closed; Fig. 5, an elevation showing the relief-valve opened and the parts immediately therewith connected, the view being taken in the direction of that of Fig. 2; Fig.6, a horizontal section taken on the line 00 x of Fig. 3; Fig. 7, a top view of the eye of the relief-valve stem and Fig. 8 an elevation of the parts shown in Fig. 4, but modified by omitting the guide-stem in the lower end of the eye.

The same letters denote the same parts.

The present improvement relates, mainly, to the relief-valve, so called, and the parts immediately therewith connected.

Referring to the drawings, A represents the main chamber of the valve, and in which the movable portion of the valve mechanism is held and operated. The inlet to the valve is at B and the outlet at O. The main valve D seats at d, and is attached to the stem cl. The latter, at its upper end, is provided with an extension, E, that is mortised or perforated transversely at e, to receive the eye of the relief-valve stem, and above the perforation c is perforated longitudinally, at e, to receive the relief-valve stem, and provided with the seat 6 upon its upper end. F G represent cupleather valves, the first attached to the stem 61 beneath the extension E, and the second to the extension E, beneath the seat 0 and conveniently held inv place by screwing the exten- (Model) sion E onto the stem cl and the seat 6 out the extension E, as shown.

H represents what is termed the reliefvalvo. Itseats upon the seat 6 as seen in Fig. 4, being furnished with suitable packing, h, and it is attached to the stem h, which is held and arranged to work up and down in the perforation 6, and which, at its lower end, is connected with the eye W, the connection being preferably effected by screwing the stem into the eye, as shown. The eye h and the perforation c are relatively suitably proportioned and shaped to enable the eye to be moved up and down in the extension E sufficiently to open and close the relief-valve H.

I represents the lever connected with the customary fl0at(not shown)in the water-closet. The lever is pivoted at i, vibrates in the side chamber, a, and is connected indirectly with the main valve D and directly with the reliefvaive H, as follows: The arm i of the lever extends and engages in the eye 7L2 of the reliefvalve stem, causing the eye and relief-valve to move immediately with the lever, and ultimately the main valve to move as the eye, above or beneath, as the case may be, encounters the extension E, the operation of the inecl1- ter) into the chamber 6 within the extension E, and thence out through the chambcra into pot. The groove 71.3 in the top of the eye 71. provides a channel for the escape of the water after the eye h has encountered the roof of the chamber 6. The float continuing to descend after the eye h ,in its upward movement, has encountered the extension E, the latter also is raised, and the main valve thereby unseated, permitting the water to pass the main valve, as indicated by the arrows in Fig. l. The water from the main then flows into the pot, causing the float therein to rise again.

The inner arm, t, of the lever I then descending draws the eye It and relief-valve 11 down- Ward until the eye k encounters the bottom of the chamber 0, whereupon the entire valve mechanism is forced by the float downward in the valveehnmher A, and the main valve D is seated. Thus the movements both of the main valve and of the relief-valve are initiated and insured by the action of the float-lever I operating positively upon these parts. The water from the main passes into the uppermost part of the 'alve-chamher,above the valve G, by means of the side pipe or passage, K, the inlet to which is at is, beneath the main-valve seat, and theoutlet atk. The ofiiee of the valve H is to relieve this pressure from the main from above the valve Gr when it is desired to lift the valve D. The amount of water flowing through the passage K is regulated by the screw-plug L. The stem of this plug is threaded at l, and is made to screw into a. hearing at l, and the outer end of the stem passes through a stuffing-box, Z, By screwing the plug inward the inlet in the passage K is diminished and the pressure transmitted through the pussage thereby diminished. Thus from the outside of the valvechambcr the valves can be adjusted to the pressure in the main.

In place of the box 1 and having the stem of the plug L pass entirely through to the outside of the valve-chamber, a removable cap can be arranged to be screwed onto the bearing I, over the outer end of the stem, and the joint can be packed by means of packing within such cap.

To assist in guiding the movement of the ward. The valve-chamber has thensnalcapfill.

I claim 1. The combination, in a \t1tel'-ClOSGh valve, of the valve D, stem (1, extension E, having the perforation c, the valve H, stem It, eye ha, and lever I, substantially as described.

2. In it Witter-closet valve, the combination of the main valve D, stem d, extension E, and the relief-valve H, the latter being seated and working in the upper end or extension of the main-valve stem, substantially as described.

3. The combination of the chnmberA, valve 1), stem (1, extension E, leathers F Gr, valve H, stem 71/, eye 7L2, and lever I, substantially as described.

4. The combination, in n Wnter'close't valve, of the main valve, relief-valve, and float-lever, snid lever being; connected directly with and positively moving the relief-valve, and the latter in turn being connected with andpositively moving the main valve, the movement of the relief-valve being, in opening and closing, in advance of the movement of the main valve.
