DEFINITION

Classification: 401/174

(under subclass 172) Implement wherein one of said elements is directly connected to the piston for movement therewith and the other of said elements is in driven relation to a member which is accessible to the hand, so that movement of said member will effect the relatively rotational force-applying motion.

SEE OR SEARCH THIS CLASS, SUBCLASS:

182, for an implement including a piston whose actuating rod consists of threaded members and wherein the operation of the screw means serves to enlarge or diminish the combined overall length of the members before or after, but not during, the force-producing actuation.
