TO ALL WI'IOM IT MAY CONCERN:
Be it known that I, EDWARD' A.. ROCK, of Lydlnw, in the county of Windsor, and State of Vermont, have,
invented a new and improved Vzilve; endldo hereby declare that the following is a. full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, formingpart of this'specication.-
The object oi this invention is to form a valve for the stoppagel :ind passage of steam` wat-er, or gas, or I other fluids or liquids, in such a manner that the const-ant use of the saule shall not injure the joint or canse the valve to leak; and the invention consists in the arrangement of an open-ring valve on the valve-stem, which, when the valve is closed, shall be expanded by a stationary wedge in the valvc-seat, as'nilkbe hereinafter described. A
Figure 1 represents a longitudinal section of the valve through the line :c a: of lig. 2.
Figure 2 is a. cross-section of fig. 1, through the line y y.
Sixnirlan'letters of reference indicate corresponding parts.
A represents the shell of the valve. B is thcvalve-stem. C is the not through which the valve-stem passes,
and by which the valve is operated. D is a smiling-box around the valve-stem. E is the hand-wheel. F is a disk, permanently attached to the end of the valve-stem. G is the ring-valve, which is loosely held on a shoulder on the disk F by a loose washer, H, and a screw, J, which enters .the stem by a scre'\v-thread, as seen in the drawing. As seen in the drawing, the valve is closed. he pipes which convey the liquid or [luid are attached to the shell at L L. m represents a'wedge, which is attached to the sheikh-phon oneside of the seat, with itshpoint or narrow end up or pointing toward the valve-stem. As before stated, the ring-valve is open, and u. wedgeshaped piece removed to correspond with the wedge. In the cross-section, (iig. 2,) the ring and wedge are seen in contact, as when the valve is closed.
It will be seen that the open portion of the ring being forcedhy the screw-stomen to the stationary wedge, the ring will be expanded and tightly close the apertures ff, when it reaches a point near the bottom of its seat, as seen in iig. 1. The ring rnay pass in loosely, and be less in diameter than the seat, but at the right point the wedge will expand it, so that it will form a tight joint. 'Provision is ina-.1e for any wear, either in the ring 01' wedge, by u space, g, below the ring.. This valve never needs grinding, has n vertical uiotion only, or does not revolve, and it leaves a clear and unobstructed passage l'or the flow of the liquid.
Having thus described my invention.' I claim as new, and desire to secure by Letters Patent- 1. The combination of' the wedge m, shell A, und valve G, substantially as herein shown and described. 2( The combination of the ring G and the wedge-m, substantially as herein `:et forth.
