ABSTRACT:
A bar-type puller having a cross block with a central section and a pair of end sections with a forcing screw threadably mounted in the central section. A pair of work-engaging members, such as pulling jaws, can be radially and axially adjustably mounted on the cross block by end sections of the cross block having spaced-apart arms to define spaces therebetween which receive the work-engaging members for infinite lateral adjustment along the arms. The work-engaging members have spaced-apart pins which span the top and bottom of the arms, with a slight clearance to facilitate lateral adjustment. The pins are caused to move into binding relation with the cross block when the work-engaging members are under load to lock the members in radially adjusted position. There is also provision for axial adjustment by providing additional spaced pins on the work-engaging members providing an alternate mounting location for the members to the cross block.
