ABSTRACT:
An article transferring device for exchanging workpieces between first and second paths is disclosed. The device utilizes vertical reciprocal movement and 180.degree. rotational movement to operate apparatus which grips workpieces traveling in the first path, raises them, transfers them to a position above the second path, lowers them into the second path and releases them. Cams responsive to vertical movement are provided for changing the spacing of each pair of workpiece grippers from a first spacing at the first path to a second spacing at the second path.
