BALL-COCK FOR WATER-CLOSET VALVES.

SPECIFICATION forming partofnLetters Patent No. 545,348, dated August 27, 1895.

Application led March l1, 1895.

Ball-Cocks for Water-Closet Valves, of which the following, taken in connection with the accompanying drawings, is a specification.

l This invention relates to improvements in ball-cocks for water-closet tanks, and it is carried out as follows, reference being had to the accompanying drawings, wherein- Figure l represents a central vertical section of the improved ballcock. Fig. 2 represents a horizontal section on the line 2 2. shown in Fig. 1. Fig. 3 represents a horizontal section on the line 3 3 shown in Fig. 1; and Fig. e represents a side elevation ot the improved ball-cock, showing the tank in which it is arranged in section.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

A in Figs. l and 4C represents a Hush-tank, as usual, to one end of which is secured a bracket B, supporting the cylindrical valveoase C, the lower end of which is open and provided with a suitable stuffing-box D, through which projects downwardly the delivery-tube E, the lower end of which extends below the liquid A in the tank A and nearly to the bottom of the latter, as shown in Fig. 4. The upper end of the tube E is closed, as shown at E in Fig. l, and to it is attached at this place a valve E, preferably made of leather, rubber, or other similar material.

Cis the upwardlyprojecting neck of the valve-case G, and within it is detachably secured the valve-seat holder F, within the lower portion of which is fitted the cylindrical glass valve-seat G, the upper end of which abuis against an annular shoulder F on the interior of the valve-seat holder F, as shown in Fig. l. By this arrangement the glass valve may easily be removed in case of breakage or repairs.

g isa rubber packing located between the exterior of the glass valve-seat G and interior of the valve-seat holder F, so as to eect a water-tight joint at this place. The upper Serial No. 541,309. (No model.)

end of the removable valve-seat holder F is preferably made outwardly aring'or conical, as shown at fin Fig. 1, and made to tit against a corresponding conical gronndsurface O in the upper end of the valvecase neck C', as shown. To the upper end of the valve-seat holder F is iitted the water-supply pipe Ijl, having a ground tapering or conical lower end h, adapted to lit against the interior upper conical surface of the valveseat holder F, as shown in Fig. 4, and secured in such position preferably by means of an annular shouldered nut I, as shown.

On the outside of the valve-case C is clam ped the vertically-adjustable bracket K, to the lower end of which is pivoted at 7c the lever L, which surrounds the pipe E and is provided With slots la it', through which project pins c c, secured to the pipe E, as shown in Figs. 1, 3, and 4.

M is the Boat-lever, which is pivoted at m to the bracket K and provided with the usual float-ball M', as shown in Fig. 4.

The free end of the lever L is pivoted ,at n to a link N, the upper screw-threaded end of which projects through a perforation in the float-lever M, and is provided above the latter with anadjustable nut N", as shown, for the lpurpose of changing the normal level of the water desired to be maintained in the tank A. By the use of the intermediate lever L, connected to the float-lever and the valvepipe E, a shorter ball-lever may be employed, as on account of the double leverage shown a ball-lever of the ordinary length will serve to close the valve against an increased` pressure in the supply-pipe H.

The glass valve-seat G above mentioned is non-corrosive, smoother, and more perfect than a metallic seat. It is very hard, andthe soft leather or rubber valve which acts against it retains its softness and thereby causes when brought against it to form a perfect closing fit not attainable in other kinds of valve-seats.

Below the upper end of the valve-pipe E are made side perforations e e', as shown in Figs. 1 and 2, through which the liquid from pipe H is conducted through the pipe E into the tank A when the valve E is moved away from its seat G.

ICQ

On the inside of the valve-ease O are preferably made radial projections C3 O3, adapted to serve as guides for the upper end of the supply-pipe H to iiow by said valve into the Valve-case C and through side perforations e e into the pipe E and to the lower sealed portion of the liquid contentsof the tank A in a quiet adpd noiseless manner. As the liquid in the tank A rises to its normal level, the oat-lever M and its float M cause the valve E to be closed against its seat G, preventing any iow of the liquid from the supply-pipe H until the level in the tank A falls below the normal one, and so on.

lVhat we Wish to secure by 4Letters Patent and claim is In a ball cock for water closet tanks, a valve case having arrangedwithin it a valve seat and a vertically movable valve pipe arranged in said valve case and opening downward by the pressure of the water, combined with a float lever carrying at one end a float balland its other end pivoted to a xed support, a lifting lever pivoted to the valve pipe and fulcruxned at one end to a xed support, and a connecting rod pivotally connected at one end to the free end of the lifting lever and at its other end adjustably secured to the ioat lever, and means for effecting the adjustment of said lever, substantially as described.

In testimony whereof we have signed our names to this specification, in the presence of two subscribing witnesses, on this 26th day of February, A. D. 1895.

JAMES CRAWFORD. JOSEPH H. YOUNG.
