Abstract

19,745. Hamilton, J. B. Sept. 14. Seats. - Relates to that kind of stop valve in which the seat comprises a ring- like body 5, which fits in an opening formed either in a partition 2 that divides the valvecasing, or in an opening formed in the body of the valve, the sides of the opening and of the ring 5 being shaped so that the ring is held in position both frictionally and positively. This invention consists in shaping the opening and the ring so that the latter is more securely held in place than heretofore. For this purpose the sides of the opening are shaped so that they first slope inwardly and downwardly at 3, and are then sloped outwardly and downwardly at 4, the exterior of the ring 5 being shaped to correspond and to engage therewith. The lower face 61 of the flanged portion of the ring 5 rests upon the edge 21 of the opening, and the upper face 6, which cooperates with the valve, is of such an area and shape that, when the valve is partly raised from its seat, there will be an excess of pressure acting downwardly on the face 6, and tending to hold the ring 5 in place. Saw-cuts 11 impart a spring- like action to that part of the ring which lies within the opening. The parts 4, 5 may ba screwed together. In a modification, the part 3 is horizontal instead of inclined.
