Abstract
A saw guard for a circular saw having a saw blade and a work piece holder which moves relative to the saw blade to cut the work piece, the saw guard being mounted on the leading edge of the work piece holder and having means for moving the saw guard into a shielding position adjacent the cutting edge of the saw blade while the work piece holder is in a restocking cycle.
Claims5
A saw machine having a work piece holder which moves the work piece into contact with a moving saw blade by relative motion of the holder and blade during a cutting cycle and which may be opened to replace the work piece during a work piece restocking cycle;
- a saw guard mounted on the leading edge of the work piece holder, means for holding the guard in a retracted position so that it does not shield the saw blade during said cutting cycle, and means to move the guard into shielding position adjacent the cutting edge of said saw blade during the time when the work piece holder is in said work piece restocking cycle.
A saw machine having a work piece holder which moves the work piece into contact with a moving circular saw blade by motion of the holder past the saw blade during a cutting cycle, said holder having an upper clamping member which may be raised vertically to restock it with a fresh work piece, said work piece holder having vertical and horizontal frame members, a saw guard having a generally U-shaped body member hingedly mounted on a leading frame member, a fluid actuatable cylinder having a piston rod, the piston rod being connected to said U-shaped body member, said cylinder and said U-shaped body member being located in a position such that when said piston rod is fully extended said body member shields the cutting edge of said saw blade adjacent said work piece holder and when fully retracted said body member no longer shields the cutting edge of said saw blade, a first and second valve means and associated actuating means which communicate a source of fluid under pressure with said fluid cylinder at a location to extend said piston rod when the work piece holder is in both a noncutting position and said clamping member is vertically raised to permit restocking, said valve means being actuated by said actuation means to communicate the fluid source with said fluid cylinder at a location to retract said piston rod when said clamping member is lowered to hold the work piece in said work piece holder.
