WARREN HYDE AND JACOB SCHWARZLEB, OF NEW YORK, N. Y.

BALL-CO CK.

Specification of Letters Patent.

Patented Mar. 17, 1914.

Application filed January 17, 1911. Serial No. 603,118.

To all whom it may concern Be it known that we, WARREN HYDE and JACOB SCHWARZLER, citizens of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Ball-Cocks, of which the following is a specification. V

This invention relates to ball cocks or flush tank valves, and its object is to provide a simple, compact and eflicient device embracing the valve, the ball, the lever and its pivot so that the complete device may be manufactured and supplied to be inserted in the supply pipe as will be more fully described in the following specification, set forth in the claim and illustrated in the drawings, wherein Figure 1 is a vertical sectional view through the valve, illustrating the operation of the ball. Fig. 2 is a sectional view on the line 22 of Fig. 1.

The invention comprises an outlet pipe section 5, having its upper interior end threaded to receive the valve seat 6, which is provided with a flange 7, at its upper end for the coupling 8, and suitable washers and packing are arranged between the joints to prevent the leakage of water. The lower end of the valve seat is constructed as at 9, to provide a limited opening against which fits the valve 10, while its stem 11 extends downward and carries the guide wings 12 to retain the valve in its proper position and cause it to work on vertical lines only. Near the lower end of the stem 11, is a slot 13, through which passes the pivotal end 14 0f the lever which carries the ball 15, and at one side of the casing 5, a recess 16 is pro-' vided in which the section 14; is pivoted on the pin 17, and as the float l5 rises in consequence of the supply of water increasing, the valve 10 closes and the supply of water is shut off. When, however, the tank is drained, the ball 15 drops, carrying with it the lever and valve 10, opening the supply pipe 9 and allowing the tank to again fill. This construction provides a compact and simple device for automatically opening and closing a valve for a flush tank, and is made of few and simple parts so that the device may be supplied to plumbers and in stalled in water supply cisterns for flush tanks. In case repairs are needed, the device may be quickly removed and replaced. it is obvious that the parts may be otherwise arranged without departing from the essential features above shown.

lVhat we claim as new and desire to secure by Letters Patent is,

In a ball cock, the combination with a float and lever; of a vertically disposed casing having an inlet and an outlet, and provided with a longitudinal opening in the side, and further provided with a laterally extending channeled portion, a second casing fitted within and being substantially shorter than the first-named casing, the said second casing being provided with a narrowed portion forming valve seat, a valve bearing up and against the said valve seat, the stem of the valve being provided with an extended spider having an opening, the lever being pivoted in the said channel and extending through both of the said openings.

In testimony whereof we aiiix our signatures in presence of two witnesses.
