DEFINITION

Classification: 91/183

(under subclass 170) Apparatus having a member, linkage or transmission connected to each of the working members and arranged to impart relative movement to one working member when the other is moved or to constrain each of the working members to move relatively in some predetermined relation.

SEE OR SEARCH THIS CLASS, SUBCLASS:

194, for expansible chamber motors disclosing plural, relatively movable working members connected to a rotary shaft by an unclaimed transmission and in which the valving for each working member is actuated by another working member.

472+, for motors having three or more cylinders arranged in parallel, radial, or conical relationship with a rotary transmission axis and particularly subclass 496 for positive bidirectional drive to the reciprocating members within radially arranged cylinders and subclass 507 for positive bidirectional drive of the reciprocating members within parallel cylinders.

73, Measuring and Testing,

245+, for meters having parallel working members which drive a common shaft extending transverse to the axis of said working members.

92, Expansible Chamber Devices,

61+, and especially subclasses 68+ and 76 for expansible chamber devices having relatively movable, interconnected working members.
