Abstract
The cold circular saw comprises a base with a saw table, a saw arm hinged to the saw table and supporting a power driven saw blade, a linear power transmitting mechanism hinged between the swingable saw arm and the stationary machine base to move the saw arm in the feeding direction, and a hydraulic cylinder-and-piston unit hinged between the machine base and the saw arm parallel to the feeding power transmitting mechanism to exert a positive biasing force in the direction opposite to the feeding direction, thus eliminating the play in the hinge of the saw arm and in the hinges of the feeding device.

A method of eliminating play in a cold action circular saw of the type having a machine base adapted for supporting a workpiece, and a swingable saw arm hinged to said base and being adapted for supporting a power driven saw blade and feeding means operable to move said arm at a feeding pressure against said base, comprising the step of exerting a correcting pressure against said arm in a direction opposite to that of said feeding pressure, said correcting pressure being applied to the same side of the hinge of the saw arm as the feeding pressure.
A method of eliminating play in a cold action circular saw of the type having a machine base adapted for supporting a workpiece, and a swingable saw arm hinged to said base and being adapted for supporting a power driven saw blade and feeding means operable to move said arm at a feeding pressure against said base, comprising the step of exerting a correcting continuous pressure against said arm in a direction opposite to that of said feeding pressure, said correcting pressure being larger than the combined force formed of the weight of said arm and of the maximum variable components of the cutting force acting in the feeding direction.
A cold circular saw comprising a machine base adapted for supporting a workpiece;
- a saw arm hinged at one end thereof to said base and being adapted for supporting a power driven saw blade;
- a linear power transmitting mechanism hinged between said base and said arm to displace under a feeding pressure said arm against said workpiece;
- and play correcting means hinged between said base and said arm to exert a counter pressure which is sufficient to eliminate play in said arm and said feeding device.
