ABSTRACT:
A loading and unloading mechanism including a workpiece receiving and discharging chamber and pressurized air/vacuum source operatively connected to the chamber. The chamber is tubular and adapted to be connected to the spindle of a lathe in a coaxial relationship. Pressurized air is used to force the workpiece into the lathe spindle and vacuum pressure is used to draw the workpiece out of the lathe and back into the tubular chamber. The device may be modified to facilitate vacuum unloading only in the case in which the lathe is manually loaded. A proximity switch is provided for detecting the passage of a finished workpiece out of the lathe and back into the chamber whereupon the chamber is opened and the workpiece is discharged.
