Description:

Abstract:

My invention is adapted for regulating the movements of steam-valves or other mechanical elements whose movement requires arrest at the end of a definite stroke; and the object of the invention is to obviate the jar and the noise produced in ordinary dash-pots at each stroke of the piston, while arresting the movements of the latter with perfect certainty.

Claim:
