<p>A circular saw for elongated work pieces particularly of metal has a saw blade mounted on an arm which is connected by a pivotal mount to a saw frame at one end and which is pivotally connected to a piston and cylinder type raising and lowering assembly at its other end. The arm can be longitudinally moved both with respect to the mount and with respect to the raising and lowering assembly which allows the blade to saw through work pieces of relatively large cross-sectional dimensions.</p> |
