Abstract
Abstract In this device an arm having side-by-side workpiece holding chucks is slidably and pivotally mounted on a supporting shaft which is turned by a motor to pivot the arm into and out of a production machine from and toward a workpiece loading-unloading station. At a first position in the machine the arm tracks linearly on the shaft so that a first chuck picks up a finished workpiece from the machine. Subsequently, the arm indexes to a second position in the machine and tracks linearly on the shaft so that a second chuck deposits an unfinished workpiece into the machine prior to the return to the loading-unloading station for recycling.

417 words
A device for cycling workpieces between a workpiece loading-unloading station into and out of a machine having vertically oscillating workpiece support means therein comprising a single horizontally extending arm, a support plate secured to one end of said arm, separate and independent first and second workpiece holding chuck means for independently gripping and holding first and second separate workpieces, securing means for Fastening said chuck means in a side-by-side relationship on one end of said arm, each of said chuck means extending vertically from said support plate and each having opposing workpiece gripping means relatively movable toward and away from one another for selectively releasing and gripping separate first and second workpieces, vertically-extending track means supporting said arm for movement in a vertical direction and for clockwise and counterclockwise turning movement into and out of said machine, first motor means for vertically moving said arm and said first and second chuck means to predetermined positions with respect to said track means, a pivot axis, means mounting said track means for turning movement with respect to said pivot axis, second motor means for turning said track means and said arm with respect to said pivot axis, first stop means operatively connected to said track means for stopping the turning movement of said track means and said arm in a first rotary direction at a first station within said machine whereby said arm and a first of said chuck means can be vertically moved on said track means to pick up a finished workpiece from said workpiece support means from any vertical position thereof, second stop means operatively connected to said track means for stopping subsequent turning movement of said track means and said arm in said first rotary direction at a second station within said machine whereby said arm and said second of said chuck means can be vertically moved on said track means to load an unfinished workpiece onto said workpiece support means, and control means for subsequently effecting the turning movement of said track means and said arm in a second rotary direction opposite to said first rotary direction to move said finished workpiece out of said machine toward said loading-unloading station, and third stop means operatively connected to said track means for limiting the turning movement of said track means and said arm to a position vertically aligned with said loading-unloading station so that said first chuck means can unload finished workpiece and simultaneously said second chuck means can be loaded with an unfinished workpiece.
