FLUSHING-TANK.

SPECIFICATION forming part of Letters Patent No. 409,147, dated August 13, 1889.

Application filed May 13, 1889. Serial No. 310,499. (No model.)

To all whom it may concern.-

Be it known that I, JAMES GREENHALGH, a citizen of the United States, residing at VVoonsocket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Flushing-'lanks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has relation to improvem ents and means for flushing water-closet bowls, and relates more particularly to the mechanism for operating and controlling the valve of the outlet-pipe.

The invention will be fully understood from the following description and claims, when taken in connection with the annexed drawings, in which- Figure 1 is a longitudinal central sectional view of a tank with my improvements applied, showing a new form of valve. Fig. 2 is a plan view of the same. Fig. 3 is a side elevation of the operating-lever removed. Fig. 4 is a vertical longitudinal sectional view of a tank, showing my improvements applied to another form of valve and overflowrpipe; and Fig. 5 is a similar view, showing still another form of valve and overflow-pipe.

Referring by letter to the said drawings, A indicates a tank, which may be of the form usually employed, and B indicates a supplypipe having the usual valve a and afloat for opening and closing the same.

0 indicates the downpipe or flushing-pipe leading from the floor of the tank to the hopper, and D indicates an overflow-pipe. By reference to Fig. 1 of the drawings it will be seen that this overflow-pipe is arranged within the tank and directly above the downpipe, and in such construction serves the additional function of a guide for the flushing or downpipe valve, as will be presently explained, the said overflow having its lower end arranged at a suflicient distance above the tank and the upper end of the downpipe, as shown at b, to form a passage for the free discharge of the water within the tank.

In Fig. 4 of the drawings I have shown the overflow-pipe with its lower portion carried horizontally to form a seat for an ordinary plug-valve, and at which point the water is ordinarily admitted to the down pipe, the overflow having communication with the downpipe, as shown, while in Fig. 5 I have shown a common form of outlet or down pipe and valve with an overflow leading from the tank to the downpipe outside of said tank.

From the foregoing description and illustrations it will be readily apparent that my improvements are adapted to serve in conjunction with any ordinary flushing-tank and valve, as will be hereinafter more fully set forth.

E indicates the operating-lever. This lever is of a form substantially as shown in Fig. 3 of the drawings, having an aperture (1, whereby the same is journaled on a suitable bearing in one of the side walls of the tank, and is provided with a short arm 6, which serves as a standard for the pivotal attachment of a lever F. This operating-lever is also provided with an integral branch or arm f, carrying a suitable stop 9, and is provided atits outer end with suitable means for the attachment of aweight, the opposite end of said lever having attached to it a pull-chain G, which is designed to extend within convenient reach of the arm of aperson. This pullchain may depend freely from the operatinglever, so that it may be grasped by the occupant of the closet, or in some cases it may be attached to the seat of the closet, so as to operate automatically, or it may be attached to the door, so that the hopper may be flushed by moving the door on its hinges.

H indicates a lever which is j ournaled on a suitable bearingin one of the side walls of the tank, and may be journaled on the same bearing h as the operating-lever E. This lever H has its free end or outer end connected with a valve, which may be of the form '0' (shown in Fig. 1 of the drawings) or a common plugvalve, such as shown in Figs. 4 and 5. I prefer to employ a valve such as shown in Fig. 1, which is arranged within the overflow pipe and guided thereby, and is designed to close the downpipe C when let down and check the discharge of water from the tank.

It will be observed that the valve shown in Fig. 1 of the, drawings is hollow, and that an opening is formed between the lower end of the overflow-pipe, as shown at I), and the top of the downpipe. New, by having the valve 1' hollow it will be seen that it will serve etfectually to open and close communication between the tank and the downpipe, and will also serve as a means of conducting the water from the overllow into the downpipe.

This valve is connected with the lever It by means of a chain 2" or other suitable device. This lever II is furthermore provided at or near its journal end with a lug or shoulder K,designed to engage by a similar lug or shoulder L on the forward under side of the pivoted lever F. The lever I has its forward end adapted to prepondcrate, so that when pressure or weight has been removed or less ened on the opposite end of said lever its lug or shoulder 1) will be allowed to engage the shoulderon. thelever ll. The shorter or lighter end of this pivoted and shouldered lever 1 is connected to the arm of the Heat M. by means of achain 1 or other suitable flexible connection. It will thus be seen that as the float rises by the action of the waterin the tank the lever F,by.its gravity, willbe allowed to come in readiness to engage the shoulder on the lever ll, when the water will cease to flow into the tank. Now, as the operator pulls upon the chain G the shoulder on the lever F will be brought in engagement with the shoulder on the lever ll, and the operator releases his grasp upon the chain the weight S will cause the lever E to be re-turned on its pivot, and the levers .l[ and F being in engagement they will also be returned 011 their pivots and the valve lifted, when the water will be allowed. to discharge through the dewnpipe until the float has descended to a low point, when the chain 1 will draw the shoulder of the lover I! out of engagement with the shoulder on the lever ll, thereby allowing the valve 1 to drop to its seat and shut olt' the flushing action.

In practice the lever It may have a stopsuch as Rt;o limit its downward movement, and the weight on the inner end of the operating-lever-such as Smay be of any suitable form.

While I have described the parts inthe exact construction illustrated, yet- I do not wish to be confined to such, as it is obvious that the form of operating-lever may be changed, as well as the shape of the lovers 1* and II, without departing from the spirit of the invention.

llaving described my invention, what I claim is l. The combination, with a flushing-tank, of a pivoted operatingdever having one end weighted, a preponderating lever carried by the operatinglever and provided with a shoulder, and a pivoted slmuldcred lever adapted to be engaged by the preponderating lever and connected with the outlet- *alve, substantially as specified.

2. The combination, with a flushing-tank, ot a pivoted lever weighted at one end, a pivotcd lever connected with a discharge-valve, and a preponderatin g lever adapted to engage and be moved by the lever connected with the valve and having its lighter end connected with a tloat, the said preponderating lever being journaled on the operating-lever, substantially as specified.

In testimony whereof I aftix my signature in presence of two witnesses.
