BALL-COCK.
Specification of Letters Patent.
Patented Nov. 2, 1915.
Application filed May 13, 1913. Serial No. 767,294.
To all whom it may concern Be it known that 1, JOHN J. CUNNING= HAM, a citizen of the United States, residing at Gadsden, in the county of Etowahand State of Alabama, .have invented certain new and useful Improvements in Ball-Cocks, of which the following is a specification.
My invention relates to improvements in ball cocks, and pertains more particularly to float-operated ball cocks for use in shutting off the supply of water to a flush tank.
The object of this invention is to provide a ball cock so constructed that the water. in passing therethrough is not discharged directly against the valve, and the valve, when closing, closes in the direction of flow of the water, thus preventing the lodging of sediment or rust from the supply pipe between the valve and seat, and consequently resulting in leakage. I l
A further object is to so connect the valve with itsstem that the valve may be moved along the length of the stem, and the heightto which the float rises before closing the valve may be varied, and in this way the height to which the water rises in the tank, and consequently the quantity of water, may
be arbitrarily regulated.
A still further object'is in providing the parts of the cock of such construction and assemblage that ready access may be had to any one of the several elements and as the parts are made interchangeable, new parts can be supplied when the original structure becomes broken or worn.
This invention consists of certain novel features and combinations of parts which will be hereinafter. fully described and pointed out. v
In the accompanying drawings: Figure 1 is a view in side elevation of my improved form of mechanism; Fig. 2 is a longitudinal, vertical, sectional view more clearly to illustrate the internal arrangement of the several parts; Fig. 3 is a transverse, vertical, sectional view on the line 3.3 of Fig. 2; and Fig. 4 is a detail, sectional view to illustrate more clearly the relation of the valve stem and valve-actuating lever.
The casing proper of my improved cock is made in two members. The member 1 has connected therewith a supply pipe 2 from the source of water supply or from the main, and member 3 has t e outlet pipe 4 connected to communicate with the chamber 5 formed in the center thereof. The chamber 5 is on its open end screw-threaded, and the screw-threads thus formed on the member 1 engage with the screw-threads on the member 3, and hold the two parts connected together. A reentrant neck 7 is formed in the bore 8 of the member 1, and a valve seat 9 is constructed on the inner end of this neck. A cap 10 is screwed or otherwise secured over the open end of the member l and any communication from the supply pipe 2 to the outlet pipe 4 must thus be through the bore 8 of member 1, through reentrant neck to the chamber 5 of member 3, and thence to the outlet pipe 4. A valve 11 is located in the bore 8 of the member 1 beyond the outer end of the reentrant neck 7 and is adapted to fit the valve seat 9. The valve 11 is carried by a stem 12, the latter moves freely through an orifice 13 formed in the closed end of member 3' Through that portion of the valve stem 12 protruding beyond the orifice 13, a slot or opening 14 is formed. A valve-actuating lever 15 is pivoted at one end as at 16 to the member 3, and passes through the slot 14 of the valve stem 12. This valve-actuating lever has rounded surfaces which bear against the ends of the slot 14 and thus the friction, as the lever is rocked to seat and unseat the valve, is reduced to a minimum. A bell crank arm 17 is pivoted to the member 3 at a poinLbelow the pivotal connection 16 of the actuating lever 15, and preferably in alinement therewith. A stem 18 is secured to the bell-crank lever 17, and on the outer end of the stem a float 19, which may be of the ball or any other approved type, is mounted. A link 20 connects the free end of the bell-crank lever 17 with the free end of the valve-actuating lever 15, and thus as the bell-crank lever is actuated through the up and down movement of the float the valve is opened and closed. The end 21 of the stem 12 on which valve 11 is mounted is screwthreaded, and the valve may be adjusted along this screw-threaded portion so that the height to which the float must be raised to close the valve may be changed to suit the requirements. Theusual after-fill pipe 22 communicates with the chamber 5 of the valve 11 is unseated" water will be supplied -member 3, and it will be seen that as the 5 u through this pipe, and as the float falls, due to the lowering of the water in the tank, and the valve is opened, water will be supplied to this pipe 22 to counteract the suction caused through the water seal, and will thus maintain the seal at all times.
The operation of the device will probably be apparent to those skilled in the art, but to repeat briefly; assuming the parts to be in the position shown in Fig. 2, the valve is closed and the water in the tank is at the height indicated, thus holding the float in its elevated position, and maintaining the valve in its closed position. The valve, to release water from the flush tank, is opened. The dropping of the float 19, due to the lowering of the water,.. causes the bell-crank lever to be actuated, and through its connection with the valve-actuating lever 15, the valve is moved away from its seat, and the water is permitted to flow into the chamber 5 of the member 3. At this position water is supplied through the after-fill pipe 22 to maintain the water seal, and through the outlet pipe 4 to re-fill the flush tank. As the opening from the flush tank is of greater dimension than the outlet pipe 4, the out-rush of the water in the tank is relatively greater than the inflow, and consequently the water is removed from the tank to such a degree that the valve controlling the outlet therefrom returns to a closed position, and the supply from the outlet pipe 4 of the ball-cock continues until the float is raised to the position shown in Fig. 2, when the valve is again in its closed or seated position, and the supply of water from the supply pipe 2 is cut oft.
It is evident that slight changes might be made in the form and arrangement of the several parts without departing from the spirit and scope of my invention, and hence I do not wish to limit myself to the exact description herein set forth, but
Having fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. A. ball-cock comprising a supply-pipe adapted to be secured in the flush-tank, and the upper end of which terminates in a hollow, transversely -extended member having one end screw-threaded and having an internal concentric reentrant neck located opposite the outlet of the supply-pipe, and having a valve-seat at one end, a member screwed to one of the screw-threads, the interior of which is in communication with the interior of the first-named member, and provided with an outlet-pipe, a valve-stem slidably supported therein, a lever and float mechanism for moving the latter, and a valve secured thereon in position to automatically seat itself upon the valve-seat on the reentrant neck.
2. A ball-cock comprising a supply-pipe adapted to be secured in theflush-tank, and the upper end of which terminates in a hollow, transversely-extended member screwthreaded' at both ends and having an internal concentric rentrant neck located oppositethe outlet of the supply-pipe, and having a valve-seat at one end, a member screwed to one of the screw-threads, the interior of which is in communication with the interior of the first-named member, and provided with an outlet-pipe, a valve-stem slidably supported therein, a lever and float mechanism for moving the latter, a valve secured thereon in position to automatically seat itself upon the valve-seat on the reentrant neck, and a cap removably secured over said valve and having a recess therein which receives the end of the valve-stem to assist in guiding and centering the latter.
In testimony whereof I aflix my signature, in the presence of two witnesses.
