ABSTRACT:
A defecting or cut off saw inludes a support for boards and a transversely movable rotating saw blade for cutting the boards to length or cutting away defects therein. The transverse movement of the saw blade is controlled by an electrical circuit, the operation of which is acutated by the simultaneous depression of a pair of spaced cycle switches. The control circuit includes a timing circuit permitting movement of the saw across a board only when both of the cycle switches have been operator actuated within a predetermined period of time of one another. The circuit provides infinite stroke control for returning the saw blade to its start position at any time when one of the cycle switches is released.
