EDWARD MCSTEEN, OF PITTSBURG, PENNSYLVANIA.
IMPROVEMENT IN VALVES.
Specification forming part of Letters Patent No. 116,619, dated July 4, 1871.
against its seat by means of a wedge actuated by a screw oi l. tl 1e stem. ,The nature of my invention consists in the use ot' a pernmlnent incline plane, forming part of the shell, and in combination therewith a single valve, on the back of which are two wedges carryin between them a deep nut, in which the screw on the lower end of the stem works, and so arranging the parts with relation to each other as that the valve will be forced down and against its seat by the action of the screw driving the wedges between it andthe permanent incline; also, combining the nut with.
the wedges in such a manner as that the lateral deviation ofthe wedges in their movement on the permanent incline will not interfere with or aliect Ythe right position of the valve, nut, or stem.
Figure lV represents a side view oi' my stopvalve; Fig. 2, longitudinal vertical section, the valve represented as being open; Fig. 3, transverse vertical section, the valve represented closed; Fig. 4, tace ot' the valve; Fig. 5, perspective view ot' the double wedge; Fig. (i, perspective view of the nut; Fig. 7, perspective view, showin g the nut as applied to the wedges.
I make the valve-shell A in any desirable form, and with the usual stuffing-box, stem, handle, coimeeting-screws, te., incident to such stopvalve-s, with this addition, a permanent incline, B, opposite the face of the valve-seat s. The operating-stem K is provided with a collar, N, resting in the stuiiing-box, which allows it to turn on its axis but prevents its upward or downward movement. 0n the lower end of this stem a screw is cut, which engages with and works in the long nut e placed between the wedges e c, so that an arm, b, on each side of the nut will extend into and rest each in an appropriate recess, h, made across the wed for that purpose, while the reverse side of the united wedges carries, by means of a projection shown, inFig. 2, the circular valve t. The parts, on being constructed and put together as shomi, will, on turning the handle D to rotate the screw X in one direction, force the nut down, which will carry with it, by means of its arms b I), the wedges c e and valve t attached thereto, so that the valve will be brought directly over its seat s, when, by an additional turn of the screw X, the wedges c 0 will be forced down between the valve t and the incline plane B on the opposite side ot' the shell, pressing the valve tightly against its seat, the recesses h IL in the wedges c o allowin the arins b b of the nut e to slide therein and give it play, by which all lateral strain is taken oiil the stein k. By reversing the motion ol" the screw X the wedges will be drawn up on the incline lz, releasing the pressure on thevalve t preparatory to its upward mov ement.
I claim- The long screw-nut e furnished with arms I) b,
duplex wedges c c, the permanent incline B, valve t, serewon the stem k, in combination with each other andthe iin-losing-shell A, when said parts are constructed, arranged, and made to operate together in the manner shown and set forth.
