  • Patent number: 4281954
    Abstract: The conveying apparatus for the bi-level irradiation chamber has a lifting device which cooperates with a bi-level rotary lock to introduce individual articles (piece goods) into the lock and to remove the articles from the lock. The lifting device allows an individual article to roll into one level of the lock while positively blocking entry of the following articles. Individual trollies are used to convey the articles within the irradiation chamber. The lifting device employs a catch to hold a trolley in position in the rotary lock to receive an article as well as a release device to release the catch after an article has been placed on a trolley.

  • Patent number: 4274789
    Abstract: A pallet loader particularly suitable for use in loading pallets onto a truck comprises a guide structure mounted at the loading end of the truck and a slide frame slidably mounted in the guide structure and an elevator mechanism mounted at one end of the slide frame. The slide member is slidably mounted on the guide structure for movement between an extended position in which the elevator mechanism is disposed outwardly from the loading end of the truck and a retracted position in which the elevator mechanism is disposed in an overlying relationship with respect to the bed of the truck. The elevator mechanism is operable when the slide frame is in the extended position to engage and raise and lower unattached load units. The slide frame is provided with a drive mechanism for driving it longitudinally of the frame so as to move palletized load units carried thereby longitudinally onto and off of the loading end of the truck.

  • Patent number: 4248563
    Abstract: A system for the so-called "cube" storage and retrieval of a large number of items, such as loaded pallets, employs a frame providing a plurality of parallel storage paths arranged in one-upon-the-other rows and side-by-side tiers. Each path provides a plurality of stations each able to store an item, and is provided with a motor-operated reciprocating advancing member which extends substantially the full length of the path. The advancing member carries for each station a driving advancing apparatus engagable with the item therein to move it to the next successive station as the member moves; it also carries a detector apparatus, which may be constituted by the respective driving apparatus, to detect the presence of an item at a station and prevent the feeding of an item to an already occupied station. The entry and delivery ends of each path are provided with respective detectors to control movement of the advancing member to ensure that the delivering station is always occupied.

  • Patent number: 4242024
    Abstract: A fork lift mechanism is associated with apparatus for palletizing long sheets of strip material at the discharge end of a shearing press. The long sheets are palletized on an underlying conveyor having a width corresponding to the length of the sheets in the direction of discharge from the press. The fork lift mechanism is supported above the conveyor for displacement toward and away from the shearing press in the direction of the discharge and is adapted to be elevated and lowered relative to the conveyor. The fork lift mechanism is operable to receive and support a plurality of short sheets from the press to form a stack on the fork lift mechanism and to position a plurality of such stacks on a pallet on the conveyor and in side-by-side relationship on the pallet in the direction of press discharge and/or in the direction of conveyor movement.

  • Patent number: 4239443
    Abstract: A stable hoist for loading and unloading articles (10) onto and from shelves (11) includes a base housing (12) from which extends a cruciform-shaped standard (13). A slide arrangement (14) mounted on the standard and driven by a power source (46 and 47) mounted in the housing moves a boom (16) up and down. The boom comprises a slide (20) and a trolley (21) from which depends a clamp (22) to grip the article. Inverted L-shaped arm structures (28 and 29) extend from the crossarms (26 and 27) of the cruciform-shaped standard (13). Stabilizing plates (48 and 49) are pivotally mounted in arm sections (33 and 34) to engage the shelf during a loading or unloading operation. The weight of components mounted in the base housing (12) and on the cruciform-shaped standard (13) act to counterbalance the tilting force during a loading and unloading operation.

  • Patent number: 4234029
    Abstract: A pneumatic vehicle tire having a single layer radial carcass of steel or a material of similarly high strength. The carcass is anchored by being looped around the bead cores in the beads. The laterally outwardly lying free ends of the carcass layer may extend up to about half the height of the tire side walls. Laterally outwardly, next to the looped around carcass end, between the rim flange and this carcass end, there is provided a bead reinforcer which includes pull-resistant threads or the like which are parallel to one another. The bead reinforcer is slanted with regard to the carcass, preferably extending at an angle of about 15.degree. to 45.degree. to the circumferential direction of the tire. The radially outwardly lying free end of the bead reinforcer has associated therewith a strip which extends parallel to said free end and includes pull-resistant threads or the like which are arranged in a cord layer.

  • Patent number: 4232990
    Abstract: This invention relates to a winch-actuated extendable tongue for boat trailers and the like that is characterized by the winch being so located and reaved with respect to a pair of telescoping elements that it is effective to positively drive the tongue into extended as well as retracted position regardless of whether the load thereon is such as to extend or retract same. More specifically, the winch is mounted on the outer of the two telescoping elements for movement therewith and its cable is reaved from an initial point of attachment on the inner of said telescoping elements, around the winch drum several turns, over a pulley on the end of the outer element remote from the initial point of attachment, back again toward the latter to a second pulley on the adjacent end of the outer element, around the second pulley and toward the remote end of the outer element again to a second point of attachment on the inner element.

  • Patent number: 4232612
    Abstract: A wall lining sheet, particularly, but not exclusively, for lining the interior end walls of freight railway cars. The wall lining sheet comprises a metal sheet having a plurality of spaced-apart attachment tabs each defined by a configured slot extending through the sheet. Each of the tabs has a bendable free end portion whereby the bendable free end portion may be displaced outwardly from the plane of the sheet. The wall lining is particularly useful in relining the interior surface of corrugated end walls of freight railway cars after the end wall has been deformed and reshaped substantially to its original state.

  • Patent number: 4231710
    Abstract: A tiltable trailer is provided with longitudinal beams spaced such as to be located directly beneath the wheels of equipment to be hauled thereby, eliminating the need for heavy cross pieces beneath the deck for the supporting wide loads, thereby contributing toward decreased trailer weight. A lower deck height is accomplished by having the tracks for the rollers of the reciprocable undercarriage and the ramps of such tracks located within the beams, by positioning the undercarriage between the beams and by providing the undercarriage with a low-profile beam support which, in turn, has roller-mounting cross members immediately ahead of and immediately behind the wheel and axle assemblies.
