ATTACHMENT FOR SUPPLY-TANKS.

SPECIFICATION forming part; of Letters Patent No. 376.292, dated January 10, 1888.

Application filed May 16,1887. Serial No. 238,321. (No model.)

I To all whom it may concern.-

, Be it known that WILLIS B. CHAMBER- LIN, a citizen of the United States, residing at Worcester, in the county of \Vorcester and State of Massachusetts, have invented certain new and useful Improved Attachments for Sure Supply-Tanks, of which the following is aspecification.

This invention relates'to the so-called so re supply-cisterns for water-closets, the object being to provide improved means for controlling and regulating both the supply and discharge valves, which is accomplished by the mechanism illustrated in the accompanying drawings, forming part of the following specification, and clearly pointed out in the appended claims, reference being had to the drawings, ofwhich- Figure 1 shows a sectional elevation of a supply tank or cistern to which my improvements are applied; and Fig. 2 is a similar view, but showing the valves open.

Similar reference-lettersindicate corresponding parts.

A is the tank or cistern; B, the supply and G the discharge pipes, the former being pro vided with the ordinary ball cock or valve, B, its rod or tube 1) connecting the Valveopcrating armb with the loaded sphere or ball b*, which is designed to float upon the surface of the water, and thereby control the supply of water to the tank, as hereinafter fully explained.

For the discharge-pipe C any of the valves in present use by the trade may be applied,

that shown in the drawings being an ordinary valve, 0, having a flap cover, 0, hinged, as shown, and provided in its top with an overflow-pipe, c, rising within two inches (more or less) of the top of the tank A.

A pull-chain, D, passes over agrooved pulley, E, located on top of the tank,as shown, and is attached to the cover 0 of the dischargevalve 0. Aloose branch chain, D, connecting the chain D with the rod or tube 12, is also provided, for a purpose hereinafter explained.

In Fig. l of the drawings both supply and drain valves or cocks are represented closed, and in Fig. 2 both are shown open. The dotted line X in each view represents the surface of the water in tank.

The pulley E is provided with a counterweight, e,which must be sufficient to overloadauce the weight of the hinged cover 0 when the same 'is open, as seen in Fig. 2, and the branch chain D is of the required length and 'l,wheu the pull cord or chain D is pulled the pulley E, cover 0, and branch chain D assume the position sh own in Fig. 2,the counter-weight e of the pulley E holding the hinged cover of the cock 0 open, thus permitting a full discharge through the pipe 0. At the same time, as the water lowers, the supply-coclgwhich is controlled by the movement of the loaded ballfloat bffiis gradually opened, causing an increase in the supply as the ball drops. The outlet being so much larger than the inlet, however, the water and the ball-float b are permitted to fall to apoint shown by dotted line X, Fig. 2,

when, by means of the branch chain D and the loaded float bflwhich is sufficiently heavy to overbalance the counter-weight on the pulley E, the said pulley is returned to its normal position and the outlet or discharge valve 0 is closed, thus allowing the water and the loaded float to again rise to the point desig nated at X, Fig. 1. In this manner a simple and automatic means for cutting off the discharge from the tank or the supply of water to a closet is readily and economically accomplished.

' Having described my improvements and their especial application, what I claim, and desire to secure by Letters Patent, is-

1. In a supply-tank, the combination of a supply-cock, its operatinglever and a loaded float attached thereto, a discharge-valve, and a grooved counterweighted pulley located at the top of said tank for carrying a pull-cord which is connected thereto, the said pull-cord and branch cords or chains connecting said pullcord with the operating-lever of supply-cock and the said discharge-valve, all operating substantially in the manner and for the purpose set forth.

2. In a supply-tank, the combination of a supply-cock, its operating-lever and float, a discharge-valve and a grooved eonnterweighted pulley located at the top of said tank for carrying a pull-cord which is attached thereto, the said pull-cord and branch cords or chains connecting the latter with the operatingdever of said supply-cock and the said dischargevalve, the float on the operating-lever of said supply-cock being suflieientl y loaded to overthrow the weighted pulley at the proper time to automatically close said discharge-valve, all substantially as and for the purpose explained.

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

WILLIS B. CHAMBERLIN.
