A multi-tension hacksaw including a longitudinallly extending frame member having a first blade support member on one end and a bracket on the other end extending laterally therefrom a second blade support member pivotally mounted on the bracket, a tensioning rod having a threaded first end adjacent to the first blade support member and a second end pivotally connected to the second blade support member, an elongated crank handle threadedly and rotatably engaging the threaded first end of the tensioning rod so that rotation of the crank handle applies tension to the tensioning rod, and a tension indicator including a pointer mounted on the bracket and a tension indicia on the second blade support member cooperating with the pointer.
A multi-tension hacksaw for utilizing both bimetal blades and high speed blades comprising a longitudinally extending hollow frame member, a first blade support member extending laterally from said frame member adjacent to one end thereof and fixedly attached thereto, a second blade support member extending laterally from said frame member adjacent to the other end thereof and pivotally attached thereto, a tensioning rod extending through said hollow frame member and having a threaded first end adjacent to said first blade support member and a second end pivotally connected to said second blade support member, and an elongated crank handle adjacent to said first blade support member for reacting thereagainst and threadedly and rotatably engaging the threaded first end of said tensioning rod to apply a high tension thereto and in turn to apply a high tension to a bimetal blade mounted between said blade support members.
A multi-tension hacksaw for utilizing both bimetal blades and high speed blades comprising a longitudinally extending frame member, a first blade support member extending laterally from said frame member adjacent to one end thereof and fixedly attached thereto, a bracket extending laterally from said frame member adjacent to the other end thereof and in the same direction as said first blade support member and fixedly attached thereto, a second blade support member pivotally mounted on said bracket and extending therefrom in the same direction as said first blade support member, a tensioning rod having a threaded first end adjacent to said first blade support member and a second end pivotally connected to said second blade support member, an elongated crank handle adjacent to said first blade support member for reacting thereagainst and threadedly and rotatably engaging the threaded first end of said tensioning rod, rotation of said crank handle with respect to said first blade support member and said tensioning rod applying tension thereto and said elongated crank handle permitting the user to apply a high tension thereto and to a bimetal blade mounted between said blade support members, and a tension indicator including a pointer mounted on one of said bracket and said second blade support member and tension indicia mounted on the other of said bracket and said second blade support member and cooperating with said pointer to indicate the tension in the blade mounted on said blade support members.
