THOMAS VILLIAM RYAN, OF CONCORD, MASSACHUSETTS.
AUTOMATIC SHUT-OFF BALL-COCK.
SPECIFICATION forming part of Letters Patent No. 618,438, dated January 31, 1899.
Application filed February 25, 1898. Serial No. 671,623. (No model.)
To all whom, it may concern:
Be it known that LTHoMAs WILLIAM RYAN, of Concord Junction, in the county of Middlesex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Automatic Shut- Off Ball- Cocks, of which the following is a description sufficiently full, clear, and exact to enable any personskilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which;e
Figure l is a vertical transverse section of my improved ball-cock, represented as in position on the tank; Fig. 2, a horizontal section on line 2 2 in Fig. l; Fig. 3, a like view on line 8 3; Figs. 4 and 5, similar views taken on lines 4 4 and 5 5, and Fig. 6 a vertical section illustrating a modification.
Like letters of reference indicate corresponding parts in the differentfigures of the drawings.
Myinvention relates especially to automatic shut-off mechanism for the ball-cocks of Water-closet tanks, and is designed particularly as an improvement on the device shown and described in my Letters Patent dated April 2G, 1898, and numbered 603,030.
The object of my present invention is to simplify and increase the efficiency of the device, so that the ball and its carrying-rod may be arranged at any desired angle to the wall of the tank, thus enabling the inlet to be disposed in the corners ory anywhere it may be deemed the most effectual, and this without altering the mechanism of the cock. y
A further object is to arrange the automatic valve at right angles to the flow and yet provide a gravity-valve that shall not chatter or hammer, frequently a decidedly objectionable feature in devices of this class. Moreover, I so construct the mechanism that by simply turning off a cup-nut the ball-valve and its actuating mechanism may be at once removed for repairs andthe flow simultaneously shut off by the automatic valve.
In carrying out my improvement I make use of means which will be understood by those conversant withsuch matters from the following explanation.
In the drawings, ct represents the shank of the body of the cock, which is secured in the usual horizontal manner to the edge of the tank T, and to the outer end of which the inlet-pipe I is secured by an ordinary coupling b. Pendent from the shank a there is a hollow casing K, which forms the inlet to the tank and opens into the inner end of said shank at w, where a double valve-seat is formed.
The valve O comprises a cylinder opening at its lower end into the tank and fitted to slidevertically in casing K by means of annular ribs or beads i. The upper end of the cylinder is closed by a solid head y, on which is a leather washer fu, held by a screw z, for engaging the under edges of the seat w and closing the-flow into the tank.l Just below the head y two ports are opened through the side walls of the cylinder O, said ports bein g equal in area to the opening throu gh' the seat w. A ring provided with an annular flange g encircles the cylinder O below the casing K and abuts lthe en d of said casing. An interiorlythreaded cap-nut h is turned onto the lower end of said casing, jamming and locking said ring against it.- From the ring gis pendent a lugf, and the arms of aforked socket C are piv oted at d to said lug. The fork-arms of this socket are also pivoted atmto the valve. The
supporting-rod A, which carries the ordinary ball-fioat, is secured by an end in the socket C by means of a set-screw j. In the position shown the valve is seated and the Iiow shut off. As the water in the tank T lowers, 'the rod A, rocking on its pivot d, draws down the valve-stem, to which itis also pivoted at fm, and opens said valve. The flow then passes into casing K through ports p into hollow stem of valve and thence into the tank in a manner which will be readily understood without a more explicit description.
Vertically above the casing K, integral with and opening into shank a, there is a second casing M. The upper end of this is interiorly screw-threaded, and a screw-plug N closes it. Below this thread the Walls of casing M are provided interiorly with vertical ribs r. (Best shown in Fig. 2.) Fitted to slide in said upper casing M there is a hollow valve B, the lower end of which is closed by a conical head s, shaped to engage and close the upper valve- IOO seat w. From the apex of this head a stud t I swiveled in the screw-cap 7a by the flange g' projects, which is normally in contact with the head of screw e' in the valve O. Water from the inlet passing between ribs r fills the hollow valve B, and its weight carries it down into contact with the screw s, said valve B thus moving coincidently with the fioatactuated valve O. The ratio between the capacity of valve B and iiow between ribs r is regulated and the water continually in said valve is at the same pressure as the water below the valve, so that the weight of the metal will cause `said valve B to fall by gravity. Moreover, there is an air-chamber e above the highest upward movement of valve and above the water-level, which forms a cushion for said valve and prevents any of the racking or chattering so annoying in many devices of this class.
In the use of my improvement when it is necessary to remove the main valve O for packing or other' repairs the screw-cap 7L is turned ofi' the casing K, and the entire valve and connecting mechanism will drop out. Immediately this is done and the shut-0E valve B is released from the support of valve O it, said valve B, falls by gravityand closes the seat fw, thus at once cutting oi the flow until the main valve is again adjusted in the casing.
As the float-rod support is substantially it may, as will be seen, be rotated at will, thus projecting the iioat-rod in any direction and enabling the body of the cock to be adjusted whenever desired on the tank.
In Fig. 6 I have illustrated a modification which may be employed. A supplemental cylinder D is detachably disposed in casing M, and has a port Z registering with the inlet and a valve-seat w. The valve B works in this cylinder,and the whole may be withdrawn for the purpose of renewing the seat in valve by removing the screw-plug N.
Having thus described my invention, what I claim is- The combination of the body; the pendent casing and the ribbed easing with the valveseats between; the rotating, sliding valve in the pendent casing provided with ports; the hollow gravity-valve normally carried by the sliding valve; a plug closing said ribbed casing and forming an air-chamber above said gravity-valve; a oat-rod support swiveled on the pendent casing; and a iioat-rod pivot ally connected to said casing and to the sliding valve substantially as described.
