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.
A fastener puller for pulling a screw or a similar object having a head from a deck or another workpiece, comprising a longitudinally and transversely extending base, an elongated main body joined to the base to extend vertically upwardly, a claw and power operated means mounted to the main body for vertically reciprocating the claw between an extended position adapted for extension between the object head and the workpiece and a retracted object removed position, the base including transversely spaced, longitudinally elongated first and second legs having front end portions, and inclined first and second flanges Joined to the respective first and second leg front end portion to extend forwardly and upwardly relative to the legs, the claw, in its extended position, in part extending between the legs and being transversely spaced from the legs.
A fastener puller for pulling a screw or a similar object having a head from a deck or another workpiece, comprising, in combination:
A fastener puller for removing a screw or a similar object having a head from a deck or another workpiece into which the object extends, comprising a longitudinally and transversely extending base, an elongated main body joined to the base to extend vertically upwardly, vertically movable first means adapted for extension between the head and the workpiece for removing the object from the workpiece, and power operated means mounted to the main body for vertically reciprocating the first means between an extended position adapted for extension between the object head and the workpiece and a retracted object removed position, the base including transversely spaced, longitudinally elongated first and second legs having bottom surfaces, front end portions and rear end portions and a web joined to and extending between the legs rear end portions, the first means in its extended position, in part extending between the legs and being transversely spaced from the legs with the bottom surfaces of the first and second legs being abutable with the deck or the another workpiece, the first means including a slide member mounted to the main body for uni-axial movement relative to the main body, a shank portion connected to the slide member and a front portion, which extends forward from the shank portion, adapted for engaging the object and extending between the head and the workpiece, with the shank portion and the front portion being readily removably attached to the slide member and limited to concurrent uni-axial movement with the slide member relative to the main body, the first means having a maximum transverse dimension, and the legs having adjacent longitudinally extending edges that are transversely spaced from each other by a dimension that is many times greater than the first means maximum transverse dimension.
