Description
UNITED STATES wPATENT GEEICE THOMAS BEESIIEY, OF MUSOATINE, IOWA.
IMPROVEMENT IN BALANCED SLIDE-VALVES.
Specification forming part of Letters Pat-ent No. 134,838, dated January 14, 1873.
To all whom it may concern:
Be it known that I, THOMAS BEEsLEY, of Muscatine, in the county of Muscatine and State ot' Iowa, have invented a new and Improved Balanced Slide-Valve, of which the following is a specification My invention consists of two valve-seats on opposite sides of an elevation above or projection from the ordinary valve-seat, with a slidevalve upon each seat connected by pressurebars at their ends, which project beyond their seats, by temper-screws, which adjust the valve so as, to work steam-tight on the seats, and so as to relieve them of the pressure of the steam on the valves, which is mainly sustained by the pressure-bars.
Figure l is a side elevation of my improved valve. Fig. 2 is an end elevation. Fig. 3 is a plan view. Fig. et is a horizontal section taken on the line a' x of Fig. 5. Fig. 5 is a longitudinal section taken on the line :v x ot' Fig. 3. Fig. 6 is a transverse section taken on the line z z of Fig. 3.
Similar letters of reference indicate corresponding parts.
A represents a projection from the ordinary valve-seat, with a valve-seat, B, on its opposite sides. O represents valves. D represents pressure-bars, to which the valves are connected at their projecting ends, one being` permanently connected and the other adjustably connected by temper-screws E and F; or both may be connected by screws, if preferred. The screws E confine the valves against the seats and the screws F are to limit the pressure of the valves against the seats by steam. G represents the induction-ports of the valves; H, the induction-ports of the valve-seats 5 I, the
exhaust-passage of the valves; and K, the exhaust-ports of the valve-seats.
The pressure ot' the steam upon the valves is expended on the pressure-bars, exceptwhat is needful to keep the valve-stem tight on the seats, so that the excess is balanced on the valves. The valves rest at their lower edges on elevations L, which expose them to the steam, so as to preventv unnecessary down pressure. By lengthening the exhaust-ports a pressure-bar may also be employed between the valves at the middle to `prevent them from springing against the valve-seats. The valve-rod is attached to the pressure-bars, through which it passes at M, and the projection A is grooved at N, to allow it to pass through both the bars; but I do not limit myself to any particular way of attaching the rod.
This valve can be applied to any slide-valve described.
