ABSTRACT:
A rocking arm saw is disclosed which may be used in one mode with an operating handle as a pull-through power saw for accurate cross or angle cutting while being readily convertable by removal of the handle to a table saw for ripping or groove cutting. The saw in its free standing form comprises a cutting surface platform and work table top, a subjacent box-like machinery housing, and a base support ventilating structure sized to provide a carrying box for the housing. When used as a pull-through saw, the rocking arm is urged elastically through its forward cutting stroke and biased rearwardly to a blade retracted position. The table top is thus maintained free of blade obstruction since the blade is protectively shielded beneath the cutting surface upon the user releasing the operating handle. The motor and saw blade, mounted on the rocking arm, are adjustable in inclination about one pivotal axis and adjustable angularly on a bearing surface around a second pivotal axis to maintain the blade cutting plane square relative to the table top cutting surface.
