Abstract:
A saw comprising:a housing having an inner surface;a pivoting arm having rearward and forward ends, the rearward end of said pivoting arm disposed within an opening in said housing and said pivoting arm extending forwardly from said housing, said pivoting arm vertically pivotable relative to said housing about an axis intermediate of the rearward and forward ends;a first blade clamp disposed generally at the forward end of said pivoting arm, said first blade clamp securing one end of a saw blade;a wedge disposed within said housing, said wedge disposed adjacent the inner surface of said housing, said wedge disposed in contact with and translatable along a surface of said pivoting arm; androd linked to said wedge and extending through said pivoting arm; wherein,longitudinal translational movement of said rod causes translation of said wedge along said pivoting arm and said inner surface such that when the wedge move forwardly contact between the wedge and the inner surface causes the wedge and the rearward end of the pivoting arm to pivot downwardly and the forward end of the pivoting arm to pivot upwardly thereby causing upward movement of the blade clamp to increase the tension of the blade.
