VALVE,
SPECIFICATION forming part of Letters Patent No; 293,240, dated February 12, 1884.
Application filed August 13. 1883.
0 all whom it may concern.-
Be it known that I, J. MORTIMER GOLD- SMITH, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Valves, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.
My invention relates to a valve of the class known as a register valve, in which the valve proper, provided with openings, has a rotary sliding movement on a seat with corresponding openings, the invention being intended as an improvement on a valve for which Letters Patent N 0. 261,547 were granted to me July 25, 1882. In register-valves the face of the valve is ground to fit accurately upon the seat with such tightness that it is exceedingly difficult for any matter to getbetween the wearing-surfaces to lubricate them, so that they are liable in time to becomeworn,so as to no longer fit accurately;
One of the objects of the present invention is to obviate this difficulty by reducing the area of the contact or wearing surface of the valve orits seat, thereby enabling it to be more easily ground, and also permitting the lubricating material to have access to the wearing-surface.
The invention also consists in various details of construction hereinafter to be described.
Figure l is a longitudinal section of a valve embodying this invention; Fig. 2, a horizontal section thereof; Fig. 3, a side elevation ofthe valve proper and a portion of itsstem, and Fig. 4 a face view of the valve proper.
The valve consists of the main case or shell it, having inlet and outlet openings 12 c, and a I partition, d, between them, a portion of the said partition being ground smooth to form a valveseat, d, having a series of openings or ports, e, The valve proper f consists, essentially,of a disk having a series of corresponding ports or openings, f. The face of the said valve that bears on the seat is provided with a series of pockets or recesses, z, of the same size and shape as theports in the valveseat, thus reducing the actual contact or wearing-surface of the valve to a band lying around the edge of the said recesses. At the periphery of the valve, adjacent to the portsthereof, its under face is No model.)
\ also recessed, as shown at m, thus enabling the fluid passing through the valve to have access to the portion of its wearing-face underlying the periphery of the valveproper, enabling this portion to be lubricated by the said fluid as the valve is opened and closed. The upper portion of the valve-case a, through which the valve proper, f, is inserted, is provided witha cap or bonnet, n, which, in small-sized valves, is screwed thereto, the said cap having the guidepassage n for the valve-stem 0, operated by the handle 0. e
In my former patent referred to the movement of the valve inopening and closing was limited by a stop-projection on the handle engaging stops on the valve-stem socket, which is screwed to the case 'a.
The valve-case a is provided with a stopgroove, p, an d after the valve is properly ground to its seat it is provided with a stop pin or proj ection, T, which, by its engagement with the end of the groove 1), arrests the movement of the valve in the proper position to register cor rectly with the ports of the valveseat.
The valve-stem o is provided with a shoulder, 0", engaging a seat at the inner end of the valve-steIn-guide passage n in the cover or, to operate as a packing for the said stem, and in order to provide as'uitable connection between the valve-stem and valve, to enable them to be pressedagainst their seats in opposite directions, thevalve is provided witha tubular central hub, f having one or more projections, f", entering corresponding notches 0 in a tubular hood or sleeve, 0*, projecting downward from the shoulder o of the valve-stem. The said hood 0 and hub f receive between them the spring t, by which the valve proper and shoulder 0 of the valve-stein are pressed to their respective seats in the absence of fluidpressure in the valve;
