DAVID D. BUICK, OF DETROIT, MICHIGAN.
BALL-VALVE.
SPECIFICATION forming part of Letters Patent No. 338,477, dated March 23, 1886.
Application filed August 21, 1885. Serial No. 174,994.
To all whom it may concern.-
Be it known that I, DAVID D. BUICK, of Detroit, in the county of Vayne and State of Michigan, have invented a new and useful Improvement in Ball-Valves, of which the following is a specification.
My invention consists in an improvement in ball-valves, hereinafter fully pointed out in the claims.
Figure 1 is an elevation of the valve con1- plete, except the ball. Fig. 2 is a vertical cen tral section through Fig. 1. Fig. 3 is a top plan view of the valve, and Fig. 4 is a vertical central section through a portion of the valvespindle and the valve.
A represents the shell of the valve, B being the outlet-port, N the inlet-port, and O a cylinder on one side of the shell communicating with the inlet-port.
I represents a flange extending around the shell, and below this the shell is screw-threaded, as shown at K, and has a nut, L, thereon, so that whenit is desired to connect the valve with a tank or other vessel into which water is to be discharged a hole can be made through the wall of the vessel, the threaded part K slipped through the hole, a washer having been first put under the flange I, and then by screwing on the nut L a tight joint can be made. The inlet-port N has an enlargement, M, having a female screw-thread to engage with the thread K.
T represents the valve-seat, and S represents the valve, which I usually make of a spindle, R, long enough to reach through the top of the shell, which serves as a guide, and down through a guide, V, in the inlet-port. On spindle R is a flange, f, the diameter of which is greater than the valve-seat, and on the circumference of this flange is a screw-thread.
6 represents a washer, of leather or other suitable packing material, resting on the top of flange f, and held in position by a small nut, 01, which screws on spindle R, and by an annular nut, a, whichscrews 0n flange f, thus leaving the washer e exposed between the nuts, as shown in Fig. 4.
h represents a passage, which leads from the valve below the seat into the cylinder 0, and D represents a piston, fitting and moving in said cylinder, the bottom of said piston being packed with an ordinary cup-leather, m.
(No model.)
9 represents a spiral spring surrounding spindle R between flange f and guide V, and tends to hold the valve against its seat.
P P represent two standards rising from the shell of the valve, and between them is pivoted the ball-lever E, in such position that its short arm is directly over the piston D, and will bear on said piston when forced up. The long arm of lever E passes directly over the end of spindle It, and at its end carries an ordinary ball or float. (Not shown.)
H represents a small pipe, tapped into the shell above the valve-seat, and its object is to wash the sides of the tank in which the ball works when the valve is opened.
The operation of the valve is as follows: Vhen the valve is closed, as shown in Fig. 2, the water-pressure resisted by the valve forces the piston D against the short arm of the lever E, and thus tends to depress the long arm; but this is counteracted by the buoyancy of the ball, and also by the pressure of water on the flange f and the pressure of spring 9. WVhen the water' which buoys up the ball is withdrawn, the long arm of the lever falls and presses the spindle R downward, thus forcing the flange f and washer e away from the valveseat T, and permitting water to pass through the seat and escape through the outlet B. As
the valve opens against the water-pressure,
the weight of the ballwould not be always sufficient to depress spindle R, especially in cases of great pressure, without using a very long lever; but the resistance offered by spindle R to the downward movement ofthe long arm of lever E is counterbalanced by the pressure of piston D on the short arm thereof, so that by making the distances from the fulcrum of said lever to its bearings on piston Dand spindle R equal, and making the areas of the valve-seat and of cylinder 0 equal, the only resistance to the downward movement of the long arm of lever E will be that offered bythe spring 9,- and by varying the proportional size of the valve-seat and the cylinder the balance of the valve may be changed at will.
This construction enables me to use this valve for water-closets,which are subjected to widely-varying pressures in different cities, and still keep the float-lever within the limits of the small tank usually employed for such purposes, instead of being obliged to use a valve which closes against the water-pressure as usual.
What I claim as my invention, and desire to secure by Letters Patent, is
1. In a float-valve which closes with the water-pressure, a float-lever pivoted on the shell, a cylinder having therein a piston constantly subjected to the water-pressure confined by the valve and bearing upon the short arm of the float-lever, and a spindle passing through the valve-seat and bearing upon the long arm of the float-lever, substantially as shown and described.
2. In a float-valve, the combination of the shell containing the outlet and inlet pipes B N and seat T, with the cylinder 0, communicating with the shell below the seat by the passage h, and having therein the piston D, valve S, having the spindle R rising through the seat and shell and extending below the valve, and spring 9, surrounding the spindle below the valve, substantially as shown and described.
3. In a float-valve which closes with the water-pressure, a float-lever pivoted 0n the shell, a cylinder having therein a piston constantly subjected to the water-pressure confined by the valve and bearing upon the short arm of the fioatlever, a valve, S, consisting of washer e, flangef and nuts 5: d, and spindle R, passing through the valve-seat and bearing upon the long arm of the float-lever, substantially as described. 7 W
