ABSTRACT:
A drive means and mounting therefor for converting rotational drive motion to linear reciprocatory motion for driving tool means in linear reciprocatory motion relative to frame or cutting bar means. The drive means includes a wobble shaft drive assembly mounted directly on the cutting bar, the drive assembly having a drive shaft with the typical axial offset portion, and with gimbal means including a generally "U" shaped yoke member coupled to a drive bearing which is secured to the axial offset shaft portion. Connecting arm means are arranged in generally axially aligned relationship with the tool means, and first and second ball joints are utilized to couple the yoke to the reciprocating tool means. In this fashion, the cutting bar provides a rigid mount for the wobble shaft drive means and positive vibration-free drive motion is provided.
