SPECIFICATION forming part of Letters Patent No. 767,848, dated August 16, 1904. Application iiidrebruary 5,1904. serial No, 192,269. No model.)

To all whom it may concern:

Beit known that I, GEORGE E. STILLMAN, a citizen of theY United States, residing at Vthe city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Ball-Cocks, of which the following is a specication.

My invention has for its object to simplify the structure of parts in connection with the valve and means carried by the float-rod to actuate in opening and closing said valve and so arranged that the ball-cock may be applied to a tank to give either a top supply or a bottom supply, as may be desired.

The invention consists of the novel construction and combination of parts, as hereinafter described, and specifically set forth in the claims.

In the accompanying sheet of drawings, Figure l represents a central longitudinal section of a ball-cock, showing its valve closed, as when the supply is shut off and the float at its upper position in the tank. Fig. 2 is a similar View of the ball-cock, showing' the normal position of parts, as when the ioat is at its lower extremity in the bottom of the tank and has actuated to open the valve. Fig. 3 shows my improved ball-cock as applied to the side of a tank, as for a top supply. Fig. 4 is a similar view showing the ball-cock applied to the-bottom of a tank, as for abottom supply. Fig. 5 is a side elevation of the` valve. Fig. 6 is an end view of the valve and showing a packing-disk secured in place thereon. Fig. v is an end elevation of a strainer or screw-plug. Fig. `8 .is a central Fig. 9 is an enlarged cross-sectional view of the valvestem and its support, taken on line a: ofFig. l. Fig. l0 is a perspective view of an attachable clip for the ball-cock casing,' together with a Y-shaped extension pivoted on said clip and adapted to receive the end of the lioat-rod.

Like letters of reference indicate like parts.

A is the ball-cock casing of a tubular form and having an integral transverse partition b, situated near the central portion of the casing, so as to form two chambers in the same, as c and c. The partition b is provided with a circular opening or port c2, communicating with the chambers c and c' and formed concentric with the bore of the casing A, and said port c2 is surrounded by an annular iange that extends in the chamber c of the casing and which flange forms a valve-seat, as at b'.

D is the valve as a whole, having' an enlarged circular head CZ and an integral stem projecting centrally from one end thereof, as at d, and the opposite or front end of the head CZ is provided with a recess to receive a flexible disk (Z2. (See Fig. 6.)- The disk Z2 is secured in place Vwithin the recess of the valve D by a screw- (Z3, and said disk is arranged to find its resting-place upon the valveseat b/ of the casing.

E is a circular strainer or screw-plug having an enlarged head c and whose peripheral surface is screw-threaded to fit tightly within the threaded end portion of the chamber c of the casing. This strainer or screw-plug E has a central integral tube c projecting in the chamber c and arranged to act asa support for the stem CZ of the valve D. Said'strainer or screw-plug is provided with a series of perforations e2, formed in its head ,e thereof and surrounding its tube or valve-support, as shown at Fig. 7.

F is a screw-plug having an enlarged hexagonal head f, integral at one end, and said Y screw-plug is provided with an exterior screwthreaded portion extending inwardly of the head f and arranged to fit snug in a screw- .threaded,openingformed in the opposite end of the casing A, as at f. This screw-plugF is drilled centrally and longitudinally throughout its length to form a bearing-support for a slidable rod G. This rod has an enlarged integral collar g formed near its middle portion and arranged as a stop to prevent withdrawal of said rod when said screw-plug F is mounted in the ball-cock casing. The rod G when mounted as described has its longitudinal center in alinement with the longitudinal center of the valve D.

Between the head f of the screw-plug E and the end of the casing' A is interposed a thin metallic clip H, made in one piece,having a disk 71 which is providedy with a centrally-circular opening /1/ to fit loosely upon the threaded portion of said screw-plug F. This clip has a fork or bifurcated portion, as LZ, to project outwardly from the casing A.

The screw-plug F not only serves as a bearing-support for the rod G, but also acts as a clamp to impinge against and hold the clip H firmly in position upon the casing in the manner shown in Figs. 1 and 2.

I is a Y-shaped extension or member which has one end pivotally mounted on a pin a', secured in the fork or bifurcated portion of the clip H, and the opposite portion of said member or extension exposing two outwardlyprojecting hubs or arms vl c, provided each with a screw-threaded aperture to receive the threaded end of the float-rod j. This Y- shaped member or extension I has a spur 2, formed at a point intermediate of its pivotal center and its arms, and said spur is adapted to contact with the outer end of the slidable rod G in forcing the valve D from its seat.

The ball-cock is mounted in position upon a water-tank, as follows: The tank (designated by letter T) is provided with a circular opening formed in its side and situated near the top of said tank, as at t in Fig. 3. The portion of the casing A which contains the strainer or screw-plug E is passed through said opening t until prevented by a packingring t', which surrounds the casing and abutting an integral annular flange t2 thereof. The outer portion of the casing has an exterior screw-thread, as t3, to receive a Hangenut u, which impinges against theouter surface of the tank and holds the ball-cock firmly in position upon the same.

o is thc inlet or supply pipe, having an outwardly-projecting annular liange fu' at one end to abut against a packing-ring w, which adjoins the face of the head e of the strainer or screw-plug E.

rv is a coupling-nut mounted on the screwthreaded portion t3 of the casing A, and said coupling-nut has an inwardly-projecting annular iiange to abut against the annular iiange e of the supply-pipe fu, so that by screwing up the said nut a the supply-pipe is firmly secured to the ball-cock.

The strainer or screw-plugE has a recess formed in the outer face of its head e, as at c3, so that should the packing-ring w be compressed too far inwardly by the coupling-nut m a sufficient clearance or passage is maintained for the iow of water-pressure from the supply-pipe through the perforations e2 of said strainer or screw-plug.

The casing A is provided with a dischargepipe y, which has one end made fast within an annular flange-hub integral with the side of the casing, and said discharge-pipe y communicates with the chamber c thereof and has its opposite ends terminating at a point near to the bottom of the tank T, as shown in Fig. 3. 1

Vhen the ball-cock is mounted horizontally on the tank, as described, the clip member I-I is designed to be held or fixed in one position by the bolt f and at the same time with its fork or bifurcated portion uppermost from the casing, as seen in Figs. l, 2, and 3. In this position of the ball-cock the end of the loat-rod j would be attached or connected to the uppermost arm of the Y-shaped member or extension I, as shown.

The operation o1' myimproved ball-cock is as follows: Assuming that the tank T is full of water reaching to a level, as at a point Zin Fig. 3, when the ordinary pull-chain is operated upon to open the waste-valve (not shown) the amount of water contained in said tank will pass down and out through the wastepipe e, and as the water lowers in the tank the float-ball y" descends and by its rod connection with the Y-piece member I causes the spur of the latter to contact against thc end of the slidable rod Gr and which movement gradually forces the valve-disk (Z2 from its seat to the position shown in Fig'. 2. By this time the float-ball j will have reached its lower extremity in the tank to the dotted position indicated in Fig. 3, when the water-supply from the inlet@ will pass from the chamber c, thence through the port c2, through the chamber c', and, linally, through the pipe y to be discharged in the tank, and which discharge carries the float-ball again up to its normal position, when the valve will be closed by the pressure from the inlet.' The dischargepipe r/ is provided with a perforation, as y, which forms an air-hole to prevent siphonage when the water-supply is shut of?. To prevent rotation of the valve I) and make the same noiseless during the time said valve is open and the supply is in force, I have one side of the valve-stem CZ made Hat to adjoin a flat side formed on the support e/ oi' the strainer or screw-plug in the manner shown in Fig. 9. l

This ball-cock may be applied to operate in a vertical position upon the bottom or' the tank. In this case the end of the float-rod t7' would 4be attached in the screw-threaded aperture of the lowermost arm of the Y-piece I and the discharge-pipe y withdrawn from the casing, so that the ball-cock would operate as in the position shown in Fig. 4. By this simple construction and arrangement of parts I form a ball-cock which has the advantage of being readily applied to operate either in a horizontal or vertical position for a top supply or a bottom supply and at the saine time has the advantage in that the strainer and valve can be quickly removed from their position in the casing by simply unscrewing the coupling-nut to cleanse the strainer from sedi- IOO IIO

ment or to replace a new valve-disk when necessary.
