EDWARD BOURNE, OF PITTSBURG, PENNSYLVANIA.
IMPROVEMENT IN COMPRESSION-VALVES.
Specification forming part of Letters Patent No. 129,923, dated July 30, 1872.
SPECIFICATION.
To all whom it may concern.-
, Be it known that I, EDWARD BOURNE, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Compression- Valves; which consists in so constructing, combining, and arranging the several parts as that less power is required to force the valveto its seat than in those heretofore in use, and which is accomplished by increasing the diameter and reducing the pitch of the screw, as hereinafterexplained; also, in forming a screw on the inside of the case and a corresponding screw on the valve-carrier, into which is fitted the square end of the operating-stem in such a manner as that carrier may be rotated so as to raise or close the valve without causing an upward or downward movement of the handle; also, in so pivoting the valve to the carrier as to give it free rotation therewith until it strikes its seat, when such rotary motion will be arrested, and it may be forced tightly down without danger of grinding or destroying its face.
My invention will be readily understood by the following description taken in connection with the accompanying drawing, wherein- Figure 1 represents a compression-valve, having a portion of its case broken away to exhibit its internal structure; Fig. 2, an enlarged transverse vertical section of the operating parts; Fig. 3, a cross-section of the same on the line a a.
I construct the valve-case A in any of the well-known ways, and of anyconvenientshape,
andfor any purpose useful in the arts; but in order to accomplish the object of my invention, that part B of the case wherein the valve is intended to work has a coarse screw, 0; its full diameter cut from a point near its top downward to the outlet D. Into this is fitted a valve-carrier, E, by means of a corresponding screw thereon, and t0 the bottom end of this carrier is pivoted a valve, F, free to rotate therewith until it comes in contact with its seat G, whenthe friction of the parts will arrest said rotary movement, as hereinbefore set forth, and thus prevent a. destruction of its face by the grinding process it would otherwise be subject to. ward in the valve-carrierE is a square recess or socket, 0, into which a correspondinglyshaped end, H, of the valve-stem K is fitted, and by which it turns the carrier as a key. Above the square portion-H of the stem a broad circular flange, b, is formed that rests upon a shoulder inside the case, andabovc this any elastic packing may be placed that, when the cap L is screwed on, will prevent leakage at thatpoint. This flange 1), resting as it does between the cap L and the shoulders in the case, prevents the stem from having any other than a rotary motionimparted to it, which rotary movement turns with it the carrier E in its screw, causing it to slide up and down on the square portion H of the stem instead of carrying the stem with it, as in other valves of similar structure. At one or more places around the carrier E, between it and its surrounding case, vertical grooves S are cut the entire depth of the screw, through which water that might get above the carrier is allowed to flow back.
Claim.
