Abstract: An apparatus for pullingly removing pins from a concrete form using a lifting mechanism. The apparatus comprises a clamp assembly having a first and a second jaw connected thereto. The clamp assembly is movable to an opened position wherein the first and the second jaws are spaced a distance apart and the clamp assembly is movable to a closed position wherein the jaws are positioned in clamping engagement with the pin. The clamp assembly is moved to the opened position and the jaws are positioned generally about the pin to be removed. The clamp assembly is connected to the lifting mechnism. The lifting mechanism is moved in an upwardly direction thereby causing the clamp assembly to be moved to the closed position for moving the first and the second jaws into clamping engagement with the pin. The lifting mechanism then is further moved in the upwardly direction for pullingly removing the pin.

Abstract: A doweling tool for drilling a dowel hole in concrete to facilitate the insertion of dowels, the doweling tool having a guide bar, a support frame for supporting the guide bar, a carriage movingly connected to the guide bar, a pneumatically operated drilling tool having a drill bit connected to the carriage and a pneumatic cylinder having a portion connected to the support frame and another portion connected to the carriage. The pneumatic cylinder is operable to move the carriage and the drilling tool connected thereto in a forward direction for drilling the dowel hole and for moving the carriage and the drilling tool connected thereto in a reverse direction for withdrawing the drilling tool from the dowel hole. The carriage is rollingly supported on the guide bar by a roller assemblies for rolling movement in the forward and reverse direction.

Abstract: The device comprises a shear adapted to be mounted to the boom of a backhoe or like machinery with relatively movable members and be actuated by a powered, movable member of the backhoe. The shear comprises a generally U-shaped support member adapted to be disposed about the top of the backhoe boom. The shear also includes a pivotally mounted cutter head adapted to engage an anvil section attached to the support member to shear an item such as a metal member inserted therebetween. A cutter head is actuated by the backhoe movable member and is pivotally returned to a raised position after a shearing operation by a biasing means connected to the cutter head.
