DEFINITION

Classification: 29/244

Puller or pusher means, contained force multiplying operator:

(under subclass 700) Apparatus having means for engaging two work parts to be assembled or disassembled and means forming part of the apparatus for multiplying the force input to the apparatus (e.g., a lever, screw, force multiplying linkage, gearing, etc.) to develop the necessary assembling or disassembling force.

(1) Note. Included in this and the indented subclasses, for example, are: (a) means for removing from and applying to a shaft, a collar, wheel, gear, bearing unit, etc. (b) means for removing from or applying to any of various elements, a nonresilient tube, collar, sleeve, ferrule, etc. (c) means for removing from or applying to any of various elements, a pin, cap, key, etc.

(2) Note. Except as stated in the following notes, apparatus from preceding subclasses indented under subclass 700 and having power multiplying means for exerting a pushing or pulling force for assembling or disassembling has been cross-referenced in this or the indented subclasses.
