Abstract: A stud puller comprises a body that can be attached selectively to a hand pulling tool or to a slide hammer for removal of dents. A small bore at the forward end of the tool receives a pulling stud and a slot at the top of the tool at the leading end extends in communication with the stud passageway. An eccentrically mounted wheel in the slot may be turned forward to clear the stud passageway for insertion of a stud and then pulled back to engage the shank of the stud in a firm grip for pulling. The stop prevents the wheel from being turned too far and block the stud passageway until the stud is inserted.

Abstract: A variable impact jarring tool comprising a handled shaft with a massive impact sleeve slideable thereon. A self-tapping screw on the end of the shaft is driven to grip the workpiece and a first collar adjacent the handle serves as an anvil against which the sleeve impacts. A second collar may be fixed on the shaft in either of two positions, one adjacent the end for a full impact stroke and the other midway thereof for a limited stroke, but providing more clearance at the end for placement of the screw in close places.
