Specification of Letters Patent.

Patented Mar. 14, 1911.

Application filed August 11i, 1909. Serial No. 512,289.

To all whom it 'may concern:

Be it known that I, THOMAS W. RYAN, a citizen of the United States, residing at Concord Junction, county of Middlesex, and State of Massachusetts, have invented an Improvement in Ball-Cocks, of which the following description, in connection with theaccompanying drawing, is a specification, like characters on the drawing repre'- senting like parts.

This invention relates to a vball cock such as is used for controlling the supply of water to the tanks of water closets.

The object of the invention is to lprovide a device of this character which shall be of simple and eflicient construction capable of being readily assembled and readily taken apart and re-assembled for repairs, and to provide a device which shall be accurate in its operation and in the control of the water supply.

The nature ofthe invention will more fully appear from the accompanying description and drawings and will be par ticularly pointed out in the claims.

The drawings represent the device in its preferred form and in full size for ordinary uses.

Tn the drawings Figure 1 shows the device chiefly in longitudinal, vertical crosssection in position on the tank. Fig. 2 is a view of a detail showing a slightly dit ferent forni of construction. Fig. 3 is a bottom plan view of the plunger valve and connected parts, shown in Fig. l, removed from the casing.

The device comprises a horizontally disposed casing A adapted to be secured in any suitable manner to the top of the water tank T. Water is admitted to the casing at one end through the supply pipe, the upper portion of which is shown at B. The end of this inlet pipe B is secured by an ordinary coupling B2 to the casing. The casing is enlarged near its central portion and there provided with a downwardly projecting discharge pipe C. The fiow of water from the inlet end of the casing to the discharge opening is controlled by a horizontally movable plunger valve D co-acting with an an nular valve seat E. The valve seat Eis preferably formed on the end of a sleeve E2 fitting intothe casing and held in place by its flared end E3, being locked between the beveled ends of the inlet pipe B and the casing.

The plunger valve D is guided in its reciprocations by the extended end A2of the casing and by a transverse rib A3 projecting from the inner wall of the enlarged central section of the casing, but it may be guided in other ways, as illustrated in Fig. 2,'where the enlarged central section of the casing is shown as provided with longitudinal ribs A4 for that purpose, the recess D2 in the plunger valve allowing the readily to the discharge opening. The plunger valve is provided at its effective end .with the usual leather or fiber washer D3 held in place by a screw.

The plunger valve D is extended to form a shank D4c and the end of the shank is flattened at D5 and provided with an open `transverse slot. The shank D4 of the valve is mounted in an annular support F and this support is locked in position by a coupling F2 engaging a fiange F3 on the support F and drawing it into contact with the end of the end-portion A2 of the casing.

A lever Gr to which the rod H from the ball is connected by a suitable set screw H2 is fulcrumed on a horizontal, transverse, rcmovable fulcrum pin G2 carried in a projection F4 from the annular support F. The lever Gr is provided with a forked arm G3, and a pin G4 carrying an anti-friction roll G5 is mounted in the forked arm and engages the shank of the plunger valve in the transverse slot thereof.

The position of the annular support to insure the movement of the lever G in a vertical plane is secured by forming diametrically opposite notches A5 in the end of the end-portion A2 of the casing, and in providing the annular support F with a lug F5 adapted to enter one of said notches when the parts are locked in position. As shown in Fig. 1, the lug F5 is seated in and fills the lower notch and in this position the ball cock is in operative position for controlling the supply of water to the tank. If for any reason it is desired to repair the tank or shut 0H the water supply the couwater to pass pling F2 is loosened until the annular sup- `fromthe-notchand then thel y port F is ygiven a half rotation 4,F5 is oppositethe upper notch A5, whereupon the coupling F2 annular supuntil the lug y j lis tightened up. and the weight of the ball will act to hold the plunger valve up against the valve seat,

shutting "off the water.

in the plunger valve, andthe i I V until the pin G4 The provision of the open transverse slot end-portion D5 of the shank of the provision of the re- ,hmovable fulcrum pin G2 enables the plunger 'valve and its operative lever and the annu- 'lar support to be readily assembled, taken apart, and re-assembled. Upon removing fr @the fulcrum pin the lever and plunger valve may be rotated with respect to the'su port and its roll can be slipped the shank Vof the valve, the parts maybe replaced. Thus .the anti-friction roll G5 is Y g riveted in place.` erative position if the shoulder D6 nange F3 not disturbed and the pin G4 can be firmly When theV parts are in 0pythe rearward f or opening movement of the plunger 'valve is limited by of the'annul'ar support.

j It will thus be seen that an extremely simtple and -eiiicient construct-ionis provided by -means'of which the flow of water lmay be accurately controlled; The leverage is suoli as to insure the power necessary to force the valve against its seat to cut ofin the water upon the rising of the ball. The plunger valve is guided practically throughout its .length so thatthere can be nok binding of the parts.. The the movable sleeve can be readily r'e-ground when necessary. The danger of any rotary V.movement oi." the valve support is eliminated, and the movement of the ball-carry 5 The connection between the 'fing lever in a verticalplane is insured, while the means for reversing the position of this v'lever and holding it locked in reversed posi- "tion enables the water to be shut oii and maintained shut oii at any time required. ball-carrying lever and the plunger valve shank enables the ready assembling, taking apart and re- .Y ,assembling of the parts.
