ABSTRACT:
A mechanism for converting rotary motion to back and forth motion. The present mechanism is disclosed in conjunction with a jig saw having a blade mounted in a holder which is moved back and forth by a rotary eccentric. A stack of leaf springs is cantilevered on the frame of the saw and is attached rigidly to the holder to cause the blade to move in a substantially elliptical orbit.
