Apparatus for connecting a left-handed feed handle to a milling machine

摘要

An apparatus for adapting a vertical knee-type milling machine to accommodate a handle assembly on the left side of the machine includes an elongated rotational member having a shaft portion at one end and a sleeve portion at the other end that receives a left end of a pinion shaft. The pinion shaft and the rotational member are connected to prevent relative rotation therebetween. A clutch device can move the rotational member in an axial direction of the pinion shaft to engage an overload clutch with a driven gear to rotate the pinion shaft. Connected to the rotational member is a handle engagement device for selectively engaging the rotational member with a handle assembly.
