WATER CLOSET VALVE.

SPECIFICATION forming part of Letters Patent No. 336.523, dated February 16, 1886.

Application filed November 16, 1855. .Serial Ne. 18292?. (Ne model.)

To all whom it may 0071067711:

Be it known that I, HENRY S. LORD, of Hartford, in the county of Hartford and State of Connecticut, have invented a ,new Improvement in "Water-Closet Valves; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a side view, parts broken away for 4 the purpose of contracting the figure; Fig. -2, a vertical central section of the valve mechanism, showing the parts in their normal conditions; Fig. 3, the same as Fig. 2, showing the valve wide open; Fig. 4, a partial horizontal section, showing the connection between the spindle K and the eccentric-strap; Fig. 5, a View on a reduced scale, showing the plunger; Fig. 6, a modification of the lever S.

This invention relates to an improvement in valves for that class of water-closets in which the wasteor escape from the bowl is produced by the lifting of a plunger-valve, thereby opening a very large escape-passage from the bowl, and such, for illustration, as that known as The Hartford Sanitary Closet, but other closets employ a similar plunger-valve.

In another application, Serial No. 167 ,934, I have shown and described a plug-valve for introducing and cutting off the supply of water to the bowl for fiushing purposes, there being a lever eXtending fron the plug into such relation to the plunger that when the plunger is raised the lever will be turned, and thereby turn the plug so as to open the'valve, the lever being caught by a latch when fully opened, so as to remain open after the plunger is closed, and until a fioat acted upon by the water flowing into the bowl will, when the water has attained a certain elevation, trip the lever and pernit it to fall and close the valve.

My present invention has for its object the Construction of a valve of a puppet character,

which shall be closed and held closed by the pressure of the flow of water, but mechanically opened by the raisin g of the plunger, and held open until the proper level of water in the bowl is attained; and the invention consists in the Construction as hereinafter described, and more particularly recited in the claims.

A represents the' valve-c`ase; B, the inlet tlereto, which is in connection with the supply-pipe; C, the valve-chanber; D, the Valveseat. The inletpassage B extends around the valve-chamber, and opens to the Valvechanber through a circumferential opening, a.

E is the outlet-passage which leads to the bowl. I The rear end of the valve-chamber C is closed by a cap, F.

G is a tubular valvesten arranged in an aXial line through the valvechamber and valve-seat, provided at one end with a stud, H, which takes a bearing in the cap F, and at the other end takes a hearing in the shell, as seen in Fig. 2, free to move therein in an axial line through the valve-seat. Upon the tubular Valve-sten the Valve I is arranged, which preferably consists of an india-rubber ring adapted to set into the Valve-seat D, and so as to securely close it, as seen in Fig. 2, it extending therefrom into the valve-chamber.

-Within the tubular valve-stem G, and at the valve end, is an auxiliary valvechamber, J, into which an opening, b, from the tubular spindle G leads to the Valve-chamber 0. u

XVithin the valve-stem G is a spindle, K, free for longitudinal movement. At its rear end it carries a valve, L, adapted to close the passage b from the tubular spindle G to the valve chamber G. This spindle K extends forward and beyond the end of the spindle G, and is constructed with a shoulder, M, adapted to bear against the end of the valve sten G, but in its normal condition stands a short distance from the end of the sten, as seen in Fig. 2. The spindle K also carries an adjustable collar, N, outside the shoulder M. This collar N is internally screw-threaded to work upon a correspondingly screw-threaded portion of the valve-spindle K, and whereby it may be adjusted longitudinally. The collar is also constructed with a recess, d.

To the Valveshell a lever, O, is hung upon a fulcrum, e. This lever carries a fioat, P, and vertically over the collar N it also carres a stud, R, in a vertical guide, the stud adapted to rest upon the collar N, as seen in Fig. 2, and in rear of the recess d.

To the valve shell or case a second lever, S,

IOO

i the slonlder M comes in contact with the end of the valvesten G, and then continuing its movement, the valve-stem within the valve will also be moved rearward to open the valve, as indicated in Fig. 3, and when so opemthe lever O drops and forces the stud R into the recess d in the collar N, as seen in Fig. 3, and so that the valve will be held in its open position. It will be understood that the fioat P is in the usual relation to the bowl, so that the water flowiug into the bowl will maintain a corresponding level at the fioat and raise the float aceordingly, and also that the plunger W is adapted to open the escape from the bowl in the usual manner, this fioatand-plud ger arrangement being too well known to require detailed description.

The operation of the valve is as follows: Standing in the normal condition, as seen in Fig. 2, with the pressure of water coming through the inlet B, the water flows to the rear into the chamber C, and there hearing upon the main valve, and also upon the auXiliary valve L, serves to hold both valves in their closed condition, and so that the escape of water to the bow] in this condition is im possible. WVhen the plunger is raised to turn the lever S, the first action is to move the spindle K independent of the Valvestem G and the principal valve. This movement of the spindle K throws the valve L from its seat, as indicated in broken lines, Fig. 2, and so that the water in the chamber C may escape through the passage b, thenee through openings h in the stem G to the escape-passage E. Th's operation relieves the pressure upon the principal valve. Then a continued movement of the lever S in the raising of the plunger brings the shoulder M to bear against the stem G, and so that in such continued rear movement of the lever S the principal valve will be thrown open, as seen in Fig. 3. The plunger being raised, the water escapes from the bowl and permits the float to fall, and as the valve reaches its extreme open position, as seen in Fig. 2, the descent o'the fioat brings the stud R into the recess d in the collar N, and so holds the valve in its open position, from which it cannot be released until the fioat rises. Both the principal and auXiliary valve stand open under these conditions the flow of water is. therefore free t`rough the escape-passage E to the bowl. The plunger being dropped eloses the escape from the bowl, and the water thus flowinginto the bowl gradually fills it until at the proper of water will therefore be into the ehamber C V and still through the principal valve-opening; but the area ofthe principal valve being greater' in the chamber O than at its seat the differential pressure will force the valve toward its seat until it is completely closed, and as seen in F'g. 2, thus cutting oli' the fiow of water to the bowl. The movement of the principal valve, under the difi'erential pressure of the water and of theleverV, makes the movement of the valve so easy and slow that water-hammer cannot occur. The closing, however, is positive. The weight of the lever S may be such as to close the principal valve so quickly that the full force of the water will not be attained in the chanber C; hence the flow will continue into the chamber C after the valve is closed, and that flow being so gradual will prevent water-hammer, so that whether the valve be closed by the action of the lever V or by the differential pressure of the water the closing is equally easy and water hammer pre- Vented. The extet of movementof the valvespindle K with relation to the valvestem Gr, so as to give a greater or less advance movement to the auxiliary valve L, is adjusted by making the valve L upon or as a part of a stem, i, serew-threaded into the spindle K. The spindle itself extends forward through the shoulder, and is there provided with a nick, l, or otherwise constructed so as to be readily turned, and by such turning the shoulder M will be taken farther from or nearer to the end of the stem G, according to the direction in which it is turned. That the collar M may retain its same relative position to the stud R during such adjustment, the collar is threaded onto the spindle with the same pitch as that of the auxiliary valve-stem i. The stud g on the collar N extends outward through a longitudinal slot, m, in the casing.

WVhile I prefer the eccentrie on the lever S and its strap as the best means for imparting longitudinal movement to the spindle K and the valve-stem, this movement may be imparted by an arm constructed as a rigid part of the lever S, as seen in Fig. 6.

In the illustration I have shown the lever S as extending to the right and the fioatlever O to the left. I have done this as a convenience in illustration, but in actual use the levers will both eXtend in the same direction.
