This invention relates to manually operating tool for removal of gang-nail plates from wood members used to manufacture floor and roof trusses. The tool is comprised of a handle (2) which has a lower notched chisel jaw (1), upper grab teeth (7), and a cam lift (8) attached to the base end of the handle (2). The opposite end of the handle (2), is designed to be struck with a hammer so that force can be applied to lower notched chisel jaw (1) for penetration under the edge of a gang-nail plate in an open position. A jaw clamp lever (3) applies upper grab teeth (7) to protrude into the gang-nail plate in the closed position. Applying down pressure to handle causes rotation of the lower notched chisel jaw (1) and upper grab teeth (7) about the cam lift (8) to extract and remove the gang-nail plate from the wood surface.
La présence invention concerne un outil à main pour extraire des plaques dentées des pièces de bois utilisées pour fabriquer des poutres de plancher triangulées et des fermes. L'outil comprend une manche (2) qui comporte une mâchoire à ciseaux crantée inférieure (1), des dents de prise supérieures (7), et une course de came (8) attachée à la base de la manche (2). L'extrémité opposée de la manche (2) est conçue pour être frappée par un marteau, de sorte qu'une force puisse être appliquée pour faire pénétrer la mâchoire à ciseaux crantée inférieure (1) sous la bordure d'une plaque dentée en position ouverte. Un levier de pince-mâchoires (3) applique des dents de prise supérieures (7) pour faire saillie dans la plaque dentée en position fermée. L'application d'une pression sur la manche entraîne une rotation de mâchoire à ciseaux crantée inférieure (1) et les dents de prise supérieures (7) autour de la course de came (8) pour extraire et retirer la plaque dentée de la surface de bois.
