Description: |
Abstract:
The improvement relates to the hook and the adjacent parts by which is effected the alternate connection and disconnection of the positive working mechanism with the arm of the valve-stem. I provide an improved construction for receiving the action of the hooks to open the steam-valves. I enclose in a just sufficiently larger recess in the hook a soft-surfaced pin set in the operating part, which serves as a silent and efficient stop to restrain any excess of turning motion of the hook. I provide by the construction of the hook for performing the double function of a push-down and a means for further insuring the engagement of the hook.
Claims:
1. In a Corliss engine, having the valve stem B with its arm B', the combination therewith of the hook M, the pin B2 having an extension B3 adapted to carry the two catch-plates B6 and securing means as the bolt B4 and nut B5 and the removable head B7 and securing means B8 therefor, all substantially as herein specified.
2. In a Corliss engine, having the positively rocking part D' carrying the soft-surfaced stop T on its face, the valve-stem B with its arm B', and the cam-ring P carrying the cams P2 and P3 the combination therewith of the hook M arranged to be engaged by an outward movement of said hook and provided with the recess m larger than said stop and holding the same, adapted to allow the hook adapted to allow the hook to swing but to limit its movement. |
