ALBERT STOCKWELL, OF PROVIDENCE, RHODE ISLAND.

DEVICE FOR OPERATING WATER-CLOSET OR OTHER VALVES.

SPECIFICATION forming part of Letters Patent No. 414,340, dated November 5, 1889.

Application filed May 27, 1889. Serial No. 312,209- (No model.)

To all whom it may concern.

Be it known that I, ALBERT STooKwELL, of Providence, in the State of Rhode Island, have invented a new and useful Device for Operating ater-Closet and other Valves; and I do hereby declare that the following specification, taken in connection with the drawings making apart of the same, is a full, clear, and exact description thereof.

Figure 1 is a front view of my device, with elevation of tank and valve, showing latter closed. Fig. 2 is a side view of same. Fig. 3 is another front view showing valve open. Fig. A is a side view of same. Fig. 5 isa view of the valve.

The object of my invention is to produce a device for operating valves where water is used for flushing purposes which shall be more prompt, accurate, and satisfactory in its operation than those in use; and it consists in the construction, arrangement, and combination of the several parts and features, as hereinafter described.

My invention is more particularly designed for use in connection with water-closets, although it may be adapted to other uses where it is desirable to regulate the discharge of water from a flushing-tank.

In the drawings, A is the tank, containing water or other flushing liquid.

B is a valve within the tank A, communicating with a conducting-pipe.

Extending across the top of the tank A, and held in suitable bearings, is a rotating shaft C. lVithout the tank and fixed upon one end of the shaft 0, somewhat eccentrically thereto, is a hollow cylindrical pulley D, partially filled with liquid. Upon the shaft 0 and directly over the valve is a fixed pulley E, to which is attached and upon which is wound a lifting-strap F, connected with the operating parts of the valve B. The interior of the hollow cylindrical pulley D is divided into two compartments by partitions G and H at right angles to each other, extending from the center to the circumference and embracing one-quarter of the interior space. The partition G extends beyond the center, when it unites with partition H, and toward the opposite circumference making a narrow passage-way between the two portions of the larger or remaining interior space. The partition H is provided with ahole or passageway communicating with the interior of the inclosed portion, through which the passage of the liquid is regulated by a valve I, operated and adjusted from the outside.

A strap is attached to the pulley D at one end in the usual way, the other end projecting downward to some place from which it is convenient to operate the valve. The cylindrical pulley is also provided upon the back side with a check or stop, which defines the extent of its rotary movement whenever the strap is pulled.

Commencing with the valve closed, as shown in Figs. 1 and 2,whenever it is desired to flush the closet a pull upon the proper strap attached to the pulley D will cause the latter, together with the shaft 0 and pulley E, to rotate in the direction indicated by the arrow in Fig. 1. Such rotation of the shaft 0 and pulleyE winds up the strap F and opens the valve B, as shown in Figs. 3 and 4, in a well-understood way. The rotation of the hollow cylindrical pulley D has the effect of transferring the liquid contained therein from its position shown in Fig. 1 to that portion of the cylinder to the left of the partition H, counterbalances the weight of the valve, and holds it in an open position, as shown in Figs.

3 and 4. As soon as the liquid becomes deposited in its new position, as above de scribed, it begins to pass through the partition H, and continues to do so until it becomes 8 5 equalized upon either side. The valve B will continue open until the process of equalization sufficiently advances to change the counterbalancing power of the liquid, when it will begin to close slowly, ending with a quick and sudden movement at the last, the liquid remaining in the space inclosed by the partitions G and H passing through an aperture in the partition G, when the whole will assume its former position, as shown in Fig. 1. 5

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

1. The combination of the shaft 0, hollow cylindrical pulley D, having interior divisions G H, dividing the space into compart- Ico ments of different sizes and containing a movable liquid brought into a leverage-acting position by the enforced rotation of the said pulley D, with the valve B and suitable means for operating the same, the Whole constructed, containing a movable leverage-acting liquid, IO arranged, and operating in the manner snbwith the valve 13 and suit-able means for cpstantially as described. erating the same, the wholeco'nstructed, ar-

2. The combination of the shaft 0, the holranged, and operating in the manner substan- 5 low cylindrical pulley D, having interior ditially as described, for the purpose specified.
