ABSTRACT:
An egg transfer device having an active rotator assembly and a passive rotator assembly pivoted about a common axis above a support table. An automatic clamping device associated with the active rotator assembly is held in an unlocked or open position to allow the active rotator assembly to be loaded with egg flats. After a hatcher tray for receiving the eggs from the egg flats is disposed on top of the egg flats and the passive rotator is rotated thereover, the two rotator assemblies are rotated together about their common axis 180 degrees to their opposite position on the support table. At the same time the automatic clamping assembly is automatically moved into its locked position, thus firmly gripping the tray of egg flats securely into the active rotator assembly as it is being rotated, and stays in its locked position until the active rotator assembly is swung back separately to its original position, at which time the clamping assembly is automatically unlocked. A safety latch is provided to automatically latch the active rotator assembly to the support table, yet to automatically unlatch the active rotator assembly from the support table when a hatcher tray is positioned thereon. A rotator latch is provided to automatically latch the active and passive rotator assemblies together, and to automatically unlatch the active rotator assembly from the passive rotator assembly when the two rotator assemblies are moved into a transfer position of the active rotator assembly. A variable rate counterbalance assembly is provided to aid in rotation of the active and passive rotator assemblies.
