  • Patent number: 4566838
    Abstract: A device for transferring article storage pans between a selected storage compartment and shuttle which moves along the aisles of storage racks in a warehouse. The accumulator pan transfer device is vertically, movably mounted on the shuttle. An extractor carriage has a plurality of spaced cogged rollers and moves horizontally and upwardly on wheels located in V-shaped guides mounted on a horizontal base for engagement with a pan which is to be transferred between the device and a storage compartment. Certain of the cogged rollers are power driven and engage a series of projections formed on the bottom wall of the pan to remove the pan from the compartment and onto other of the supporting rollers for supporting the pan as it is transferred to the center of the base. Return of the extractor carriage to the center of the base deposits the removed pan onto a pair of transversely extending accumulator belts. The belts are power driven and remove the pan from the extractor.

  • Patent number: 4450400
    Abstract: A system for replacing electrical batteries in electrically powered vehicles in a minimum period of time on the order of one minute or less. Carriage-elevator structure is arranged in front of a battery charging station to transfer selected batteries between the charging station and a parked stationary vehicle. The vehicle and the charging station are provided with roller support units adapted to bear the battery weight and permit manual push-and/or pull shift of individual batteries to or from the aforementioned elevator. The system enables a substantially discharged battery to be removed from a vehicle and replaced with a fully charged battery in a very short time, e.g. about one minute.

  • Patent number: 4278395
    Abstract: A method of stocking a building under construction with wallboard panels, and apparatus. A stack of horizontal panels is delivered to the building site by truck, and removed by a fork lift truck, and then placed on a pallet provided with transverse rollers. The pallet, loaded with the stack of horizontal panels, is lifted to an upper floor, and a self-propelled transporter vehicle on that floor is placed adjacent the pallet. The stack is transferred as a unit to the transporter, which then delivers the stack to a desired location on the floor of the building, the stack of horizontal panels being discharged as a unit from the transporter.The pallet has three sets of rollers, longitudinally spaced, so as to provide between each two sets a passage which is upwardly facing, unobstructed, and which will receive one of the tines of a fork lift truck. One of the rollers is powered from a source of energy carried on the pallet.

  • Patent number: 4197046
    Abstract: A palletizer for picking up a group of stacked cans from a first pick-up position on a conveyor, transporting the cans to a second deposit position and depositing the cans onto a pallet. The stacks of cans are accumulated on the conveyor by an exit gate prior to being picked up. The cans are also aligned on the conveyor by means of a retractable can guide adjacent the conveyor. The palletizer further includes a transport carriage movably mounted on a track of a frame. The carriage includes both a lift mechanism for lifting the cans off of the conveyor and a hold-down mechanism to steady the cans while they are being lifted and transported to the pallet. Finally a push bar unloading mechanism disengages the cans from the lift mechanism and snugs them against the other cans on the pallet.

  • Patent number: 4195962
    Abstract: A platform loading system having an elevator platform mounted loader unit d a magazine mounted loader unit in each magazine served by the loader system. Each loader unit consists of one cargo tray and its associated tray transfer machinery. In each loader unit a cargo tray may occupy one of two positions, an upper position or a lower position. The load to be transferred is always carried by a tray in the upper position. Transfer of weapons between elevator platforms and magazines consists of a simultaneous exchange of a loaded and empty tray between mating loader units. The loaded tray traveling in the upper position passes over the empty tray in the lower position heading in the opposite direction. At completion of tray exchange, loaded trays may be off-loaded and the now empty tray lowered to the lower tray position by a tray jacking system as required by the next exchange operation.

  • Patent number: 4189276
    Abstract: An ultra-narrow aisle lift truck vehicle has a body including discrete front and rear portions connected by a pair of elongated stabilizing and support members. The stabilizing and support members are movable vertically in tracks on the body portions so that they provide both structural support and integrity between the front and rear portions as well as being selectively movable into and out of a ground engaging position to perform a stabilizing function. A pair of vertical masts mounted on the front and rear portions support a vertically movable carriage assembly. The carriage assembly includes a carriage having a pair of horizontally directed forks thereon which may extend into laterally adjacent opposite sides of the vehicle and return to a position within the body and between the lateral sides thereof. The carriage is mounted on an extension pantograph and is turnable about a vertical axis by means of a motor to accommodate such lateral positioning.
