DEFINITION

Classification: 188/72.6

(under subclass 72.4) Apparatus further provided with structure for converting force into motion or for connecting a part movable in one direction to a part movable in another direction or for increasing or decreasing the rate of motion or force of one part with respect to another part.

(1) Note. The mechanical linkage may be used in addition to the fluid-pressure piston (i.e., in a drive train including

both fluid-pressure and mechanical elements in series), or be used in substitution therefor (i.e., either the fluid-pressure system is used or a mechanical linkage is used).
