BALL-COCK.
SPECIFICATION forming part of Letters Patent No. 506,145, dated October 3, 189B; Application filed December 17, 1892. Serial No. 455,429. (No model.)
To all whom it may con/cern,.- V
Be it knownthat we, JAMES M. YOUNG and JOHN B. GEYSER, citizens of the United States, residing at Allegheny, in the county of Allegheny and State' of Pennsylvania, have invented certain new and useful Improvements in Ball-Cocks or Water-Valves; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make and use the same.
Our invention has relation to certain improvements in ball cocks, or Water valves for closet cisterns and tanks, and particularly to that class of valves in which the opening of a small vent in the upper part of the valvecasing or cap causes the initial pressure in the supply connection to raise the main valve and allow the water to How into the cistern or tank under full head; and in which, when the small vent is closed by the raising of the float, or other means, the pressure upon the upper part olthe main Valve will close the same gradua y. A
Our invention and improvements consist in the novel construction and combination of parts hereinafter described and claimed.
In the accompanying drawings,-Figure l is a vertical central sectional view of our improved ball-cock, with the valve seated. Fig. 2 is a similar view with the valve lifted. Fig. 3 is a transverse sectional view on the line of Fig. l. Fig. 4. is a detailed view.
Ais the supply-stem or inlet provided with suitable nut P and union joint P to secure to tank. The passage of A isunobstructed and larger in size than the service inlet at the union joint, but is provided at the top with a valveseat B, and flange S, on the outer edge of which it is joined by screw-thread to the casing C. Inside this casing, which is larger in diameter than the supply opening, is located the automatic opening and closing valve E, which moves freely in the finished walls of C, being of sufficient length to afford a Wide bearing against the wall of the casing, whereby it is self guiding and incapable of binding and has its upper edge packed by the leather disk F', secured to the valve E by the screw-ring F, the top edge, U, of which is dished to allow the water to reach the full diameter, when the operation of closing begins.' In the bottom center of valve E is screwed the pressuretube L, retaining the leather valve L', which matches the seat B, in place, by the shoulder R. This pressure-tube extends, for some distance, down into A, and even when the valve E is open,is below the orifice of seat B. This tube is unsupported by bridgeor guide, being centered and guided solely by the piston valve and hence its presence does not obstruct the passage way of the water through the inlet pipe A. The area or diameter of the pipe A, is sufficiently large to compensate for the space occupied by the pressure tube. The tube L ends-in a conical point. The main portion of the tube L has a large bore M, to within a short distance of the conical point, Where it is reduced to a very small sized passage N. The casing Chas a closing cap G, screwed on its upper edge. This cap is provided with the exit passage H, ending in the vent I. Closing this vent, is the leather K, seated in the lever J, pivoted to the cap, and controlled bya float or other means. The casing C has also the side ports D, D, D, for the water to pass into the tank, and the flange T, to prevent it from boiling upward. The vent I throws water downward.
The operation of the valve is as follows: The area of the vent I is somewhat larger, in proportion to the inlet of the pressure-tube N, than the area of the large valve-chamber of C is to the supply-valve; in other words, if the area of C be tive times the area of B, then the vent I should be at least six times the area ofthe entrance to the pressure-tube L, at N. This is vital, as it governs the automatic action of the valve. It is also a vital point to have the endof the pressure-tube L extend belowthe Vlevel of the valve seat B into the supply-stem A, so that the full pressureof the mains shall be steadily entering at N. Supposing now, that the valve is in working order and closed. Either by the fall of water lowering the float, or-by other means, the vent I is opened and discharging more fluid than enters the chamber of C by the opening N. The pressure in A, onV leather valve L, causes the valve E to slowly rise and the full volume of the supply rushes from A through B and out of the side openings D,
IOO
D,D in C,belng prevented from jumping upward by the ange T, on C. The flow through N and out of I is also continuous so long as I remains open. When, however, the tank fills and the ventI is closed by the float operating the lever J, or by other means, the supply throughthepressure-tube L, by the small opening N, continues, and, owing to the opening being below the level of the seat B, the pressure tube conveys the full pressure of the mains into the large chamber of C, and this being so much larger in area than the inlet of A, the force accumulated therein is sufficient to overcome all friction and resistance, and firmly close the supply at B.
The object of the conical point on the pressure-tube L is to allow a free passage for any foulness that may be in the fluid, and the enlarged passage M above N is to avoid the possibility of its fouling with small particles. This valve being submerged is noiseless, and the action perfect, the extension of the pressure-tubeL below the seat of B at all positions, open or closed, allowing the full power of the water pressure to be used for work, and the simple proportionng of the vent I so as to discharge more than the inlet N can supply, furnishing the movement, It will work in any position in which it may be placed, and under any grade of pressure that is sufcient to overcome the slight friction of the parts. Although we have here shown it as applied to tank use, its adaptability to many Vother uses is apparent.
We are aware that other valves and cocks have been made, having the object of using the pressure of supply vto control and close the valve, but owing to the complexity and delicacy of their parts, they have proven practical failures, not being able to meet the requirements of varying pressure and foul water.
Having described our invention, what we claim, and desire to secure by Letters Patent, 1s-
l. In a ball cock or water valve, the combination with the unobstructed inlet stem A, of the valve casing C, having outlet openings of greater aggregate area than the stem A, the plunger E, sliding freely within the casing and having its external bearing surface sufficientlylarge to prevent binding and the pressure tubeL, attached to the plunger and extending into the stem A-,When the plunger-is both raised and lowered, said pressure tube being centered and guided solely `by the piston valve, and having its upper end threaded and shouldered, and retaining in place the valve L', substantially as described.
2. In a ball cock or water valve, the combination with the hollovvr cylindrical piston or plunger having a central water way and having at its upper end an internal flange threaded interiorly and recessed on its upper face, of the flexible packing disk F', and flanged screw ring F, substantially as described.
In testimony whereof 'We aiix our signatures in presence of two witnesses. y
