  • Patent number: 5437537
    Abstract: An apparatus and method for automatically loading successive layers of similarly shaped objects, such as newspaper bundles and the like, into wheeled carts. The bundles are first delivered at a controlled rate from a source thereof to a device that arranges and delivers the objects in organized groups to an initial loading position. The organized group is then moved onto a carrier from the loading position. The carrier then moves from its loading position to a position within the wheeled cart. A blocking plate serves to prevent the objects from moving with the carrier as it move back to its initial loading position wherein the objects are deposited in the cart. The cart is held on a lift and is first moved to a top loading position for receiving the first layer of bundles and subsequently lowered the needed amount for receiving successive layers of bundles.

  • Patent number: 5320212
    Abstract: A bi-directional ratchet conveyor is shown including a carrier bar slideably mounted centrally of a frame and operated by a power cylinder. The carrier bar has a first plurality of gravity dogs pivotally secured along a first side thereof, and a second plurality of gravity dogs secured along a second side thereof oriented in an opposite direction from the first plurality of gravity dogs. Dog operating rods are slideably secured to each side of the carrier bar for independently operating the first and second plurality of dogs between active and neutral positions. Each dog operating rod is operated by a separate pneumatic cylinder. When the first plurality of dogs are maintained in an active position, the second plurality of dogs are maintained in a neutral position, thereby providing for movement of goods in one direction along the conveyor through repeated extension and retraction of the power cylinder.
