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:
