ABSTRACT:
A work transfer device for vertically transferring workpieces by means of a vertically disposed transfer bar. The transfer bar executes a motion which is somewhat in the shape of an hourglass for transferring articles one station at a time between vertically spaced stations. The articles may be transferred either upwardly or downwardly by simply reversing the direction of the drive. The drive for the transfer bar comprises a mechanism including cams and linkages for developing the hourglass type motion.
