GEORGE l1. (JONUlil, 0i? Olbthlbllt, NEW ll llllttll lli SPECIFICATION forming part of Letters Patent No. 793,991, dated July at, 1905.

Application iiled March 3, 1904. Serial No. 196,261.

To all who/it if; IN/(LZ/ concern..-

llc it known that l, tl'none n F. Conn rr, a citizen of the United States, residing at Orange, in the county of ltssex and tltate of New .l ersoy, have invented certain new and useful limproven'ien ts in Ball-Cocks for Flusl 1 ing-'l,anks, &e.; and i do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make and use the same, reference being had to the accompanying drawings, and to numerals of refer ence marked thereon, which form a part of this speci lication.

(the objects of this invention are to increase the durability and the eiliciency oif floats :for fiushing-tan ks, to reduce the cost of construction, to provide a more simple and effective device, and to secure other advantages and results, some of which may be referred to hereinafter in connection with the description of the working parts.

The invention consists in the improved ballcock for llushing tanks and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth and finally embraced in the claim.

Referring to the accompanying drawings, .in which like numerals of reference indicate corresponding parts in each of the several ligu res, Figure 1 is a vertical section of a flushing-tank having my improvements. Fig. 2 isan enlarged vertical section of the cock, and Fig. 3 is a front view of the same.

in said drawings, indicates a 'llushingtank of any suitable constructioi'i. l]. indicates the body of the cock, through which the water enters said tank from the supply-pipe 12 for flushing purposes, the said cock having at its extremity a slideway 13, adapted to receive the slide-valve 14. The said body 11 is adapted to extend vertically up from the bottom of the tank, as shown in Fig. i, being held in its standing position by any suitable means, and at its upper end is bent or turned laterally, the lateral horizontal extension being provided at its extremity with the said slideway, which is substantially vertictl, so as to permit of the vertical sliding movement of the slith-a-valve ll when acted on by the love and Heat. tlaid slide-valve is operated by a lever 15, which may be in sections '151 152, baring the ball-lioat 16 at one end and having a ball '17 at its opposite end, adapted. to enter and work in a socket 18, formed at the upper end of the said slide-valve let. The said slide-valve l-i at its lower extremity is provided with a water-passage 19, through which water may i'low out from the body of the cock. tiaid passage comprises an aperture formed in the lower part of the valve midway of its edges and extending to its lower end and an apron curved forwardly in front oi. said aperture from, the plane of the valve and to which it is integrallyattached at its edges. This apron thus serves to direct the water downward when the valve is opened, and preferably the slideway 125 extends downward below the laterally-tm'ned portion of the cockbody, so that the lip thus provided forms with the said apron a downwardly-directed spout when the valve is open. At the opposite sides of said slide-valve are arranged cars 20, which provide bearings for a stay roller or wheel 21, adapted to press against the outside of the slidc-valve and by means of which the slide held when closed in impervious relation to the body of the cock to prevent leakage of water, the said valve and seat being ground to secure greater impermeability. There are preferably two of said rollers, as shown, one close to each car, so that they bear against the margins of the slide-valve on opposite sides of the apron described.

The socket 18 for the ball end l'l'is preferably cylii'idrical to permit of the movement of said ball end in said socket in the direction of the axis of the cylinder. The fulcrum-arm 22 for the float-lever is preferably cast integrally in connection with the body of the cook, the said lever working on a pin 23, em tending through the said lever and through cars 24; of the said ifulcrum-arm in any suitable man n or.

l am aware that detail changes of construction may be made withoutdeparting from the spirit or scope of the invention, and l do not wish to be understood as limiting myselt by IO tremity a slideway disposed transversely of the said laterally turned portion, a valve mounted in said slideway and having its lower portion apertured and providing forward of said aperture an apron adapted to direct the water downward, ears projecting forwardly from the edges of the slideway, rollers pivoted adjacent to said ears and adapted to engage the slide-valve on opposite sides of its apron, and a lever fulcrumed on the said body of the cock, engaging said valve at one end and having a float at the other end for opening and closing the valve.

In testimony that I claim the foregoing I have hereunto set my hand this 25th day of February, 190%.
