  • Patent number: 4850787
    Abstract: A cargo-work vehicle for detachably supporting a container has lift arms for rotatably supporting the container and a single cooperating auxiliary arm which ensures that the attitude of the container is held constant when the container is loaded and unloaded. A dump pin is also provided for fixing the container relative to the lift arms so that the container can be rotated relative to the vehicle body for dumping of the container load. The single auxiliary arm is advantageous because it can be located centrally of the vehicle and substantially underneath the loaded container. Such placement of the auxiliary arm affords compactness, reduces costs, and allows a single auxiliary arm to maintain the desired, constant attitude of the container during loading and unloading of the container.

  • Patent number: 4804080
    Abstract: An indexing mechanism for a three-dimensional transfer press system wherein a pair of parallel spaced transfer bars are moved back and forth, up and down, and toward and away from each other for transporting successive panels through a series of press stations. A height adjustment for the transfer bars are connected between a lift cam mechanism and a rack-and-pinion linkage, the latter linking the former to two pairs of lift carriers carrying the transfer bars so as to allow their longitudinal reciprocation and movement toward and away from each other. Comprising either a multiple abutment member, a screw-and-nut assembly, or a double-acting hydraulic cylinder, the height adjustment provdes a variable length of connection between the lift cam mechanism and the rack-and-pinion linkage for adjustably varying the upper and lower limits between which the transfer bars are moved up and down.

  • Patent number: 4797057
    Abstract: A tow truck of the wheel-lift type is provided. In a first embodiment, a telescopic boom is supported by parallelogram linkage which is actuated by a hydraulic motor which is slightly inclined to the horizontal, the inner end of the boom, in its travel position being above and somewhat forwardly of the ring gear housing of the rear axle of the tow truck. The parallelogram linkage supports the boom through a boom support structure which permits it to be swung in a substantially horizontal plane, about substantially vertical pinions. The grid, which engages the wheels, includes a movable member which engages a wheel and raises it relative to the boom and grid, without movement of the boom. In a second embodiment, a substantially vertical post supports a parallelogram linkage which in turn supports a substantially horizontal extensible boom having a wheel grid at its outer end.

  • Patent number: 4795299
    Abstract: A system for moving and processing workpieces includes individual stations isolated from one another and from a main chamber by seals formed by a transport mechanism. Workpieces are moved in a queue in a circular pattern, by a dial turret operated by a bell-crank and a Geneva mechanism. Stations seal to the baseplate from below, and a vacuum chamber encloses the turret assembly which operates on a post through a center hole in the baseplate. Workpieces loaded to one depended chamber are withdrawn from chambers and inserted into next chambers in a circular pattern, passing through the main chamber with each transfer, and ending back in the chamber where they were loaded. In an alternative embodiment passages between the main chamber and each individual chamber have valves allowing processing to take place without carriers attached to the turret being in the processing chambers.

  • Patent number: 4795300
    Abstract: An apparatus for loading workpieces without exposure of a work chamber to the atmosphere comprises a transfer chamber formed in part by an inner plate section which serves as a cover plate with an inner port therethrough to the work chamber. An entry plate section has an entry port therethrough to the atmosphere, is spaced laterally from the inner port and has a door. A plurality of tubular loading members are equally spaced arcuately in a wheel member mounted in the transfer chamber. Each loading member is displaceable at a loading site between a normal position in the wheel in which each loading member is relocatable laterally by the wheel, and a sealed position proximate the entry port. A seal between the entry plate section and the loading member in its sealed position allows access of a workpiece to the loading cylinder through the entry port without exposing the remainder of the transfer chamber to the atmosphere.

  • Patent number: 4787806
    Abstract: A "hands-free" apparatus for loading and unloading piece parts from baskets containing a plurality of such parts on a ferris wheel or other type carrier for submersion into plating or cleaning tanks. The preferred embodiment is adapted for handling a plurality of metallic disks to be plated for the purpose of magnetic recording of data. The system accepts a plurality of baskets transported to it on a conveyor mechanism. The baskets are simultaneously lifted up to a load/unload position at which a mandrel is threaded through the aperture in each metallic disk. The baskets are lowered back down to the conveyor. The mandrel carrying the disks is swung onto a slot on the ferris wheel which is adapted to carry approximately twelve such disk carrying mandrels. The ferris wheel is stepped to the next slot which is loaded the same way. After all slots on the ferris wheel are loaded, the entire ferris wheel is removed from engagement with the loader and transported through the fabrication cycle.

  • Patent number: 4784567
    Abstract: An improved vehicle restraint for preventing movement of a vehicle, such as a truck away from a loading dock during a loading operation. The vehicle restraint includes a guide frame mounted on the front face of the loading dock and a hook is disposed to move vertically on the guide frame between a lower inoperative position and an upper operative position where the hook engages an abutment on the vehicle. The hook is moved between the inoperative and operative positions by a fluid cylinder assembly, including a cylinder which is disposed in a recess in the driveway adjacent the loading dock, and the piston rod of the fluid cylinder assembly is connected to the hook. By introducing fluid into the lower end of the cylinder, the piston rod will be extended to move the hook to the operative position. The compressible nature of the fluid in the cylinder enables the hook to follow rising and falling of the truck bed during the loading operation.

  • Patent number: 4778326
    Abstract: Method and apparatus for handling semiconductor chips and the like are disclosed which include the use of a flat flexible film which is attached to the face of a base member. The face of the base member is formed with recesses covered by the flat flexible film. Chips are loaded onto the flat flexible film in good surface contact therewith whereby they are securely held in position by interfacial, adhesive, or other forces between the chips and film. To facilitate removal of chips from the film, the recesses are connected to a vaccuum source, drawing portions of the flexible film into said recesses and providing the film with a texturized, or undulating, surface. The area of contact between the chips and film is thereby reduced which, in turn, results in a reduction in the force by which the chips are attached to the film, thereby enabling removal of the chips by conventional techniques.
