ABSTRACT:
A mechanical puller comprising two "U" shaped frame members one nestable within the other. The two frame members are interconnected through a pivotal bracket carried by the outside frame member. The inner frame member is attached to the outer frame member pivotal bracket by an elongated threaded bolt which passes through an aperture in the pivotal bracket. A nut and washer combination mating with the threaded bolt allows longitudinal adjustment of the inner frame member relative to the pivotal bracket. The inner frame member is both pivotal and rotatable relative to the outer frame member and longitudinally adjustable relative to the pivotal bracket.
