ABSTRACT:
A transfer apparatus has longitudinal, transverse and vertical movements. Transfer bars are mounted on a frame which moves longitudinally as a unit. The bars move transversely on the frame. A drive box mounted on a side of the frame has transverse and longitudinal drive levers. The longitudinal drive lever has a roller which slides in a transverse track in one of the transfer bars to drive the frame forward and rearward. The transverse drive lever is pivotally connected to a link which is pivotally connected to a pivotally mounted crank arm. A roller on one side of the crank arm pivot slides in a longitudinal track in one transfer bar to push that bar in and out. A slideable transverse rod pivotally connected to the crank arm on the other side of the pivot has a roller on a remote end which slides in a longitudinal track in the other of the transfer bars to push that transfer bar in and out. Carriages moveable along upwardly and outwardly slanted slide assemblies mounted on the transfer bars have rollers which engage bumpers upon inward movement of the transfer bars to push the carriages upwardly. Gripper fingers are connected to longitudinal support bars extending from the carriages.
