Abstract: A pusher is disclosed for transferring plural glass containers onto a conveyor. The pusher includes a finger for each glass container. Each finger is separately retractable after its container has been transferred onto a conveyor so as to prevent a collision between the second container and the finger for the first container.

Abstract: Apparatus for unloading material from a silo comprises a chain drive wheel located near a discharge opening on one side of the silo, a chain idler wheel, a pair of angularly spaced apart rotatable chain guide wheels mounted on a ring which is drivable in a circular path around the silo floor, and an endless flexible cutting chain reeved around the aforesaid wheels. A drive mechanism is provided to drive the ring in the circular path and to rotate the chain drive wheel to drive the chain as the chain guide wheels move, whereby reaches of the chain sweep across the silo floor to unload the material through the discharge opening. The chain drive wheel and drive mechanism therefor are located outside the opening in the silo. The chain idler wheel is located inside the silo and within the ring. Protective devices are provided on the silo floor to prevent that reach of chain extending between the chain drive wheel and the chain idler wheel from being subjected to pressure from material thereabove in the silo.

Abstract: A conveyor lift system employing an endless flexible conveyor means capable of transferring loads from an exterior position on one side to an exterior position on the other side without secondary mechanical means through the use of finger-like support elements which pass among each other without contact, and transfer the loads. The loads may be lifted off from a lower level position and moved to a higher level position, or vice versa, and the system works as well in either direction.

Abstract: A load supporting apparatus includes a base, and a platform adapted to support the load is pivotally supported on the base for movement between first and second positions, the platform becoming increasingly tilted as it moves from the first to the second position. A drive mechanism cooperable with the platform is provided for effecting pivotal movement thereof, and a control mechanism cooperable with the drive mechanism is provided for automatically actuating the drive mechanism to effect movement of the platform toward the second position in response to a shift in the distribution of the load thereon, thereby further tilting the platform and effecting a redistribution of the load. The control means is also responsive to the redistribution of the load caused by tilting of the platform for automatically deactuating the drive mechanism.

Abstract: The cargo container carrier of this invention is configured to be removably attachable to the carriage structure of a conventional lift truck. The assembly comprises a vertically extensible main frame secured to the lift truck carriage, the frame pivotally supporting a first pair of tiltable container lifting beam sections for adjustment between an operative position in which they are in longitudinal extension, for engaging an empty cargo container for transport, and an inoperative position in which they extend along the lateral sides of the lift truck in order to allow for increased manueverability of the vehicle while not functioning in the transporting of cargo containers, and for operation of the lift truck in conventional uses and in confined spaces.

Abstract: A light weight carriage having a flat bed and a pivotal ramp also includes a winch and counterbalance assembly is first hauled to the roof of a building or other elevated location. Gutter guards are then installed to the carriage and the ramp is placed in its supported inclined position. A separate platform or pallet to which a load is attached, and having a plurality of small wheels thereunder, is connected to the cable of the winch on the carriage and is winched up the wall of the building, over the gutter guards, over a wheel-protecting block on the ramp and into its final position on the ramp. The ramp is lowered and the assembly is used like a dolly to move the load to its final location.
