ABSTRACT:
A portable electric orbital jig saw of the adjustable orbit type incorporating an improved manually adjustable orbit drive mechanism which transmits smooth, continuous orbital motion to a reciprocating saw blade with no lost motion, from a full orbit mode operation to a zero orbit mode operation in which the saw blade reciprocates along a straight line. The present orbital drive mechanism includes levers operatively connected to one another in all operative positions thereof, but adjustable to vary the mechanical advantage thereof to thereby vary the degree of orbital motion of the saw blade.
