Abstract: A power option is provided for a manually-operated material lift that employs a telescoping mast system which is extended or retracted by a winch. A reversible electric motor is connected to the winch via two-way reduction gearing that remains in the drive train during manual operation and requires no clutches or disconnect means. The power option is initiated by selecting the position of a reversing switch that controls the motor, and closing an on/off switch which energizes the motor for rotation in the selected direction. When the on/off switch is open, the lift may be manually operated in the conventional manner.

Abstract: A device for freeing a snowmobile entrenched in snow, Through the use of a vertical first rod, pivoting second rod, pad and a cable, a snowmobile having ski-shaped rudders in its forward end and track-shaped belting at its rearward end can be freed from entrenchment.

Abstract: A vehicle and vehicle parts transportation system used for moving, positioning and manipulating a vehicle and vehicle parts primarily when a vehicle is damaged or in the need of repairs. The system consists of a power module having interchangeable legs and parts that allow the power module to be reconfigured as to its height, width and length and various tool modules. The power module becomes a different tool as required or desired by the operator by simply adding or removing a tool module. Each specific tool module provides the necessary lifting and motive force apparatus and means for maneuvering the tool module for performing the necessary operation.

Abstract: A compact, foldable, portable luggage carrier made of lightweight aluminum which when folded is light enough for easy hand carrying and storing. The apparatus is especially helpful for persons without sufficient strength to load luggage e.g., into an automobile trunk. The carrier is a rectangular platform on wheels with a handle structure containing a winch and pulley arrangement attached near one end of the platform. The handle structure comprises two upright posts attached at one end perpendicular to the platform and at the other end to the bottom ends of two additional posts supporting a winch, pulleys with a rope and hook for lifting the luggage and depositing it to a desired place, e.g. an automobile trunk and at the top end is a pulley arm parallel to the platform. The winch is manually or battery operated. The pulley arm's height from the platform is vertically adjusted by adjusting the top posts positions relative to the bottom posts.

Abstract: A vehicle is disclosed for automatically transporting loaded pallets within a plurality of tracks forming a storage rack. The vehicle comprises a main body having a plurality of wheels extending out of the sides thereof. A lift mechanism is mounted on the main body and is extendable therefrom for raising or lowering a loaded pallet above or onto the support surface of the tracks. Each lift mechanism comprises a pair of support bars, with each bar being connected to a pair of lifters or support elements. Each pair of lifters is jointly raised and lowered by flexible chains which extend over fixed supports and a double eccentric drive mechanism located therebetween. A horizontally positioned guide wheel also extends out of each corner of the carriage to contact the track rails and center the carriage at all times on the track. The carriage and lift mechanisms are respectively driven by a pair of drive motors located on the carriage.

Abstract: A jack is provided that is adapted to be used for lifting and handling heavy objects or loads such as vehicle engines, heads, manifolds, air conditioners and the like. The jack includes a means for permitting the device to be motor operated or manually operated. The jack is mounted on swivel wheels and the jack can be maneuvered in various directions.

Abstract: A device is disclosed and claimed herein for lifting and supporting large items requiring repair, assembly, installation, disassembly or the like. A bumper of an automobile, a door of an automobile, an automobile body panel or the like are exemplary of workpieces that may be handled by the present unit. Such items may be temporarily secured to the device of the present invention and then elevated or lowered to a proper position for assembly, disassembly, installation and/or repair of the item. Particular chain drive means permits accurate adjustment of the workpiece to a desired location for the intended operation. Means for holding the workpiece are being generally universally adjustable to properly position the work as desired. Remote switching permits operation of the device from beneath an automobile or elsewhere away from the device.
