The contents of the container are emptied into the body of the vehicle by moving the forks upwardly along the mast,rotating the lift arm upwardly and rearwardly toward the vehicle body, arm and tilting the forks into the vehicle body. In a preferred embodiment, the forks are attached along the mast arm by a chain drive mechanism carried with the mast.
Abstract: A car dumping apparatus intended for open top railway cars or other containers which are moved sequentially through a supporting frame and are rotated upwardly and to one side about a single horizontal axis to discharge the contents onto a dumping area located on one side. A first hydraulic piston motor rotates the frame and railroad car as a combination about the horizontal axis. Thereafter a second hydraulic piston motor advances the combination of frame, railroad car, an intermediate support member and the first hydraulic piston motor, as a combination, about the same horizontal axis until the open top of the railroad car confronts the dumping area whereby the contents of the railway car are spilled onto the dumping area. Economies of construction and operation are achieved as a result of the rotation about a single horizontal axis.

Abstract: A refuse compactor body has a tank section of an irregular polygonal right section that is uniform from end to end. The tank wall is made of rectangular pieces of thin very high tensile strength sheet metal and externally reinforced at spaced intervals longitudinally of the tank by polygonal peripherally continuous girth reinforcements, made up of straight short sections of metal tubes, to make a semi-monocoque structure. A floor portion of the tank is recessed between the longitudinal body support beams, which are the sole body support, to provide a relatively low center of gravity when mounted on a truck chassis. A hopper section of the body has a packer that obturates about two-thirds of the opening to the tank and is fitted at its upper edge with a follower that pivots to a shallower slope to keep refuse from falling behind the packer blade during a compaction stroke of the packer.
Abstract: A cassette-type container for a sheet-like member, includes a lower member for carrying the sheet-like member, an upper member engageable with the lower member to define a closed chamber, a guide channel formed in the upper member, for guiding rectilinear movement of the upper member when it is engaged by or disengaged from the lower member, a guide pin formed on the lower member and engageable with the guide channel so that the upper member is pivotally movable relative to the lower member, and a member for holding the upper member and lower member against separation.
Abstract: The invention is a highly maneuverable prime mover adapted for normal or orthogonal steering modes. In the normal mode true Ackermann steering is achieved. Either two or four wheel steering may be chosen. When in the orthogonal mode the vehicle is hybrid skid steered. In hybrid steering only one wheel of a side-by-side pair is steered. This greatly simplifies the necessary shifting mechanisms. Each wheel is driven by an individual hydraulic motor supplied from a main system. In the preferred version the prime mover has a turret capable of 360.degree. rotation. This turret preferably has a universal mounting capable of holding various types of lifting tools. The prime mover is especially well adapted for use with a tool head comprising an array of parallel screws or chains which can rapidly pick up, transport, and deposit objects such as container grown nursery plants.

Abstract: The wheeled frame remaining after removal therefrom of the detachable cargo container, is gripped by clamping mechanism of a carrying unit mounted on a tractor or lift truck, then elevated above the ground and pivoted from its normal horizontal disposition to vertical position, and then transported to a multiple storage unit where it is deposited and retained in said vertical position removably in one of a plurality of compartments making up the storage unit. A plurality of such wheeled frames may be stored in this manner by deposit in successive ones of the compartments, and they are removed from the compartment in the reverse order of deposit.
Abstract: A straddle carrier which may be driven over either end of a load to be lifted, the carrier having a chassis including spaced parallel elongated frame members which are connected together adjacent their ends by vertically disposed structural arches to form a rigid rectangular frame enclosing an unobstructed load bay. At least two pairs of wheels are disposed on each side of the chassis and a compressed air over oil suspension system is provided for attaching each wheel to the chassis. The compressed air over oil suspension system provides for decreasing the air space in the system to thereby enhance the stability of the carrier. A rectangular load lifting structure is disposed between the frame members and provides for guiding the load lifting structure during ascent and descent are provided to facilitate positioning of the load lifting structure from side to side between the frame members of the chassis.
Abstract: Miniature electronic component parts such as capacitors or resistors are end conductively coated by use of a part handling plate having a multiplicity of passageways therethrough with walls coated by resilient material to grip the parts. A bank of pins in a press (a) are used to move the parts in the passageways, (b) are used to load the parts into the passageways through the use of a loading plate housing part receiving openings filled with parts by the use of vibration equipment, and (c) are used to discharge the parts from the passageways into the recesses of an unloading plate. The parts are moved in the passageways first to expose one end to be coated and then second to expose the other end of the parts to be coated.
Abstract: The crop discharge spout of an agricultural machine is continuously adjusted so that the crop material discharge therefrom is always directed into an associated, but not necessarily connected, collector vehicle. An electro optical device affixed to the crop discharge spout illuminates a scanning area with an optical signal. A passive retroreflective target affixed to the collector vehicle and disposed within the scanning area reflects the optical signal back to the electro optical device. The electro optical device receives the reflected optical signal and causes logic means to generate control signals, such that appropriate utilization means aligns the crop discharge spout with the associated but not necessarily attached collector vehicle.
