  • Patent number: 4699557
    Abstract: A refuse collection vehicle has a chassis, a cab mounted to the front of the chassis, a body mounted to the chassis behind the cab for conventional dumping or for modular box transfer and a loading device or assembly. The loading device or assembly comprising forks mounted on a carriage which travels vertically along a mast. The mast being pivotally mounted to arms which are mounted for pivotal movement about an axis located above the cab. The arms rotate the mast rearwardly toward the body. 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.

  • Patent number: 4690603
    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.

  • Patent number: 4668151
    Abstract: In a plant for making concrete roof tiles, the tiles are loaded on to racks and cured in a curing chamber. Apparatus for unloading the tiles on their pallets from shelves in the racks on to an outfeed conveyor comprises a descending conveyor means having pairs of supports, the spacing of the pairs of supports being equal to the spacing of the shelves. A pusher moves columns of tiles from the shelves on to the pairs of supports which engage the edges of the tiles. A cam moves the descending conveyor away from the rack and the conveyor then is activated to deposit the tiles on to an outfeed conveyor in spaced relationship.

  • Patent number: 4648775
    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.

  • Patent number: 4498554
    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.

  • Patent number: 4432690
    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.

  • Patent number: 4376609
    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.

  • Patent number: 4370093
    Abstract: A system for orientating a railway spike of the type having a head provided with a lip which projects at one location from the head. It is important to ensure that the lip is aligned in a predetermined angular position so that when the spike is driven in a tie by means of an automatic spike driver the lip will overlie the rail flange. The system involves a holding device, such as an electromagnet for holding a spike and a drive motor rotating the holding device and spike until a light path defined between a stationary source and detector is interrupted by the lip of the spike and at which point the drive motor is deenergized, in addition, a switch indicating a complete 90.degree. rotation of the spike is also activated so that one of the flat faces of the square section shank will face the rail.

  • Patent number: 4343583
    Abstract: A stacker/unstacker for receptacles such as bread pans or baskets or the like includes a pair of laterally spaced-apart endless chains having receptacle carriers mounted therebetween for conveying receptacles between an infeed-outfeed conveyor and the top of a receptacle stack. The conveyor chains are horizontally spaced-apart in a direction perpendicular to the lateral direction with the carriers mounted for rotation about two spaced-apart axes which are respectively fixed with respect to the chains so that the carriers are stably held in a predetermined orientation and undergo only translational movement along the conveyor path. The path has a transfer portion at the top of the stack wherein the carriers and carried receptacles remain stationary for a time during which the carriers are moved between support and release conditions to pick up or deposit receptacles at the top of the stack. Indexing mechanism moves the transfer portion vertically to keep it at the top of the stack as the stack height changes.

  • Patent number: RE32001
    Abstract: Trays containing stacks of cigarettes are moved to an evacuating station above a vertically movable platform which descends as soon as the movable bottom of a filled tray is moved to its open position. The platform then lowers a stack of cigarettes from the interior of a filled tray onto the upper stretches of two intermittently driven endless belts in a magazine. The latter serves for temporary storage of such stacks prior to transport of cigarettes into a reservoir which feeds cigarettes into the hopper of a packing machine. The supply of cigarettes in the reservoir is monitored.[.,.]. and.Iadd., .Iaddend.when the supply is depleted to a certain minimum permissible value, a switch produces a signal which starts a motor for the belts so as to transfer a stack from the magazine into the reservoir.
