Abstract
An orbital-action reciprocating power saw includes a motor-driven transmission that causes a saw blade carrier to reciprocate along an axis of reciprocation and move in a direction transverse to the axis of reciprocation to provide an aggressive cutting action. The transmission includes a rotary-to-reciprocation drive mechanism defined by a rotatably driven gear having an eccentrically mounted pin that engages a slotted yoke connected to the saw blade carrier. The saw blade carrier is mounted in a `floating` bearing that accommodates both reciprocation and movement in a direction transverse to the reciprocation axis. A rocker arm is pivotally mounted intermediate its ends with one end engaging the floating bearing mount and the other end engageable with an axial-face cam portion of the rotatably driven gear. The rocker arm is effective to move the saw blade carrier in a direction transverse to the axis of reciprocation to provide the desired orbital action.
