  • Patent number: 5993133
    Abstract: An apparatus designed to carry a spare tire against the underside of a vehicle, rearwardly thereof, featuring a mounting plate, for the tire assembly, attached to the first end of a cantilever arm. The second end of the cantilever arm is pivotally attached to a carrier base frame, which in turn is pivotally suspended from support members attached to the vehicle's frame, by four suspension bars. Movement of the base frame is controlled by operation of a driver tube incorporated into the base frame, comprised of a rectangular tube, inside of which are a drive screw, and a rectangular nut. Two cables attached to the nut are directed by pulleys to the center of the back transverse member of the frame, then right and left to the two back corners, thense to a point on each longitudinal member of the frame, then vertically to anchor points on the support members attached to the vehicle's frame. Clockwise rotation of the screw pulls cable into the tube, moving the base frame forward and upward into storage position.

  • Patent number: 5993146
    Abstract: A tub-like member is recessed below floor surface level in a pit and carries therein an extendable and retractable lifting mechanism. The tub includes a horizontal outwardly extending flange essentially at floor surface level, and overlying the floor surface, which a loader/unloader may easily manipulate with foot pressure to rotate the tub and stacked articles on a pallet carried on the lifting mechanism within the tub-like member. Easily operable controls are provided for the loader/unloader to incrementally raise and lower the lifting mechanism to present the top article of a stack on a pallet at a comfortable lifting height. Also included is a new and improved mechanism for supporting a pallet for manual rotation and incrementally controlled vertical movement.

  • Patent number: 5971699
    Abstract: This invention pertains to load forming systems, especially those designed to place cased product on e.g. a pallet. The invention contemplates receiving cases at a high rate of input, and fragmenting the input, sending it to parallel processing elements of the load forming system. A layer creating subsystem has parallel processing elements, and preferably has sufficient designed throughput capacity to continue processing cases at the overall rated capacity of the case loading system when any one of the parallel processing elements in the layer creating subsystem fails. The case loading subsystem also can incoroporate parallel layer transfer elements and load forming elements.

  • Patent number: 5957654
    Abstract: A lead frame unloading apparatus includes a pair of opposing plate members, one of which has a long horizontal slit. The opposing plate members define a central space where one or more sliding blocks are located, each of the sliding blocks having a vertical through hole at its center. A picker penetrates through the vertical hole within each respective sliding block, each picker is immobilized when it contacts a lead frame for pickup thereby allowing the sliding block to move vertically up and down on the immobilized pickers, each of the pickers having a vacuum suction device at one end thereof, and a vacuum screw at the other end thereof. The vacuum screw has a hollow projection connected to a vacuum supplier. A spring is disposed beneath respective of the one or more sliding blocks, with the spring being fitted to an outside of the vacuum suction device. Spring stoppers support the springs and fastening devices fasten the one or more sliding blocks to the opposing plate members.

  • Patent number: 5954840
    Abstract: A tilting elevator is set forth. A rigid frame has a base, a structurally rigid structure extending upwardly from the base, and a flange attached to the structure top. The flange is generally parallel to the base. A movable elevatable structure is telescopically mounted to the rigid frame. The elevatable structure comprises upper and lower spaced apart generally parallel plates. At least three generally parallel rods extend between the plates and are connected to them by universal joints. A motor system is supported rigidly relative to the base. Each of the rods is movable relative to the plates independently of each other rod. A robotic arm having R-, .theta.- and Z-motion can be mounted to the elevator. A mechanism is preferably attached to the bottom plate of the elevatable structure for increasing the stability of the system. With the addition of a sensor and using microprocessor control, canted workpieces can be readily picked up.

  • Patent number: 5931625
    Abstract: A freight loading/unloading crane (10) comprises a crane bridge (16) with two lifting units (26, 28) displaceable in their longitudinal direction with a lifting system (26b, 28b) and associated load receiving device (26c, 28c) and a transfer unit (32) with at least one load receiving region (32o, 32u). To prepare for a load exchange with one of the lifting units (26, 28), the transfer unit (32) is stopped adjacent to the lifting unit in question, so that this can continue to raise or lower its lifting system (26b or 28b) independently of the position of the transfer unit (32). The actual load exchange takes place by means of an operating device (36o, 36u), without further movement of the transfer unit (32).

  • Patent number: 5806685
    Abstract: An apparatus for use in cleaning confinement houses, to be pulled within the confinement house by a small tractor, providing motive force to the apparatus and to its components, is constructed on a wheeled frame, the front of which is connected to the tractor in a manner that allows the height of the leading edge of the apparatus to be adjusted. The leading edge of the frame carries a feeder reel which breaks up the mass of litter and waste on the floor and lifts it to an inclined conveyor. The conveyor is a bar type conveyor in which a plurality of parallel bars are mounted transverse to the direction of travel of the conveyor to urge material along a fixed grate having interstitial separation of such size as to allow sifting of reusable litter from waste litter which is too soiled to be reused. A plurality of panels may be detachably affixed to the grate beneath the bar conveyor thereby allowing the user to determine the amount of reusable material returned to the floor.
