  • Patent number: 4029229
    Abstract: A lift blade assembly for engaging a stack of cartons to be lifted by a lift truck. The lift blade assembly comprises a supporting framework, a transmission mechanism and first and second lift blades. The first lift blade has a front portion and a bottom portion and is fixedly attached to the supporting framework. The second blade has a top portion and a front portion and is pivotally attached to the supporting framework upwardly from the first blade. A pusher bar is disposed above the bottom portion of the first blade for upward and downward reciprocation relative thereto. The transmission mechanism is linked to the pusher bar and second blade for transmitting downward motion of the pusher bar into forward and downward motion of the second blade. A spring is provided for urging the pusher bar upwardly from the bottom of the first blade.

  • Patent number: 4024972
    Abstract: For use with a lift truck, a lifting apparatus which combines compact height when not fully extended with extended height exceeding that of a conventional mast and frame assembly. The apparatus includes a selectively engageable transmission which drives a load-engaging and lifting member vertically with respect to the frame apparatus. The transmission is engaged to convert relative motion between the mast and frame into motion of the engaging member with respect to the frame. A significant increase is achieved in the maximum elevated height of the assembly, while maintaining the compact unelevated height of the conventional mast and frame assembly. In one embodiment of the invention, the transmission drives load-engaging members laterally to accommodate wider loads.
