  • 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: 4193475
    Abstract: A safety clamp slidably mounted on a vertical safety rail in proximity to a ladder is attached to a workman's belt by a pivotal actuating arm which shifts a wedge plate into clamping engagement with a safety carrier immediately under free fall conditions encountered if the workman falls from the ladder. The rail is spaced from the ladder mounting brackets by circular sleeves.

  • Patent number: 4071926
    Abstract: A safety clamp slidably mounted on a vertical safety carrier, such as a cable or rod, in proximity to a ladder is attached to a workman's belt by a pivotal actuating arm which shifts a wedge plate into clamping engagement with the safety carrier immediately under free-fall conditions encountered if the workman falls from the ladder. Instantaneous actuation of the wedge plate into clamping engagement with the safety carrier in response to the slightest pivotal movement of the actuating arm towards its closing position is provided by cam action exerted against the wedge plate by the actuating arm and by a cam member on the clamping bracket. Cam follower and guide surfaces on the upper end of the wedge plate cooperate with camming action of the actuating arm against the lower end of the wedge plate to maintain the wedge plate in an upright position of uniform contact with the safety carrier.
