ABSTRACT:
A fastener puller for pulling screws (38) and the like from a deck (39) or other workpiece that includes a base (10) having a planar base portion (11B, 11C) joined to an inclined base portion (14) to provide a fulcrum about which the base pivots to move the planar base portion parallel to the adjacent part of the deck as the claw (30), while extending between the insulation hold down plate (35) and the insulation (37) on the deck, is initially moved perpendicularly to the planar base portion by a piston cylinder combination (20, 21). The screw, in being removed, is moved perpendicularly to the part of the deck in which it is extended. The combination reciprocates a slider (24) along the slide mount (17B). The claw is mounted to the slider while the slide mount is mounted to the base to extend perpendicular to the planar base portion whereby the claw is moved to minimize the enlargement of the hole in the deck as the screw is separated from the deck.
