ABSTRACT:
A pull rod assembly is disclosed which includes telescoping inner and outer rod members one of which is adapted for connection to a drive member and the other of which is adapted for connection to a driven member. A pair of movable pawls are carried by the outer rod member and are operable to interlock with the inner rod member to maintain the rod members in selected axial positions relative to each other. Control means are operative to effect selective release of the pawls such that the overall length of the pull rod assembly may be varied while the driven rod member is subjected to a reciprocating motion from the drive member.
