Description

ABSTRACT:
A mechanized coping saw has a frame and handle attached thereto, the frame including a U-shaped portion with opposite leg sections having outward ends, a cavity formed within the U-shaped portion, and apertures proximate the outward ends of the leg sections which open into the cavity. An endless blade travels through the cavity of the U-shaped portion around rotating elements with a portion of the blade extending straight between the leg sections to define an exposed blade cutting section, A power drive system drives the blade through the cavity. The invention uses a pair of guide rollers which are placed along the profiled edge of a molding piece to steadily guide the blade cutting section for precise coping of the molding piece. The rollers are adjustable to provide for a variety of different cutting angles and situations. Another embodiment utilizes an elongated arced guide arm to extend longitudinally along the exposed blade cutting section for guiding and steadying the blade, Another embodiment includes a blade section cover pivotally mounted to move outwardly from the blade cutting section to expose the blade during coping.
