  • Patent number: 4573403
    Abstract: A charge door assembly for automated operation of a baler utilizes a truncated wedge-shaped door pivotally mounted to the baler at a point beneath the lowest point of travel of a conventional movable platen. The door pivots outwardly to admit a charge of material onto the platen from a feed apparatus. Intermeshing teeth are provided along the door assembly fact to separate any material extending outwardly of the door as the door closes. Sufficient space is provided between the door and the passageway therefor to allow material stringing from the teeth to be attenuated and subsequently entrained by the action of the baler.

  • Patent number: 4550657
    Abstract: A baling chamber for a fiber press utilizing rigid upright doors pivotally mounted along their lower portions to contain fibers compressed thereinto by a moving platen. The doors separate slightly at the upper portion thereof responsive to the final compression of the bale thereby reducing the lateral pressure on the bale. One of the doors has rollers thereon to cooperatively engage a track parallel therewith such that the door may be displaced for removal of the bale.

  • Patent number: 4261399
    Abstract: Disclosed is apparatus for cutting piling, trees and the like, provided with means permitting the apparatus to be placed about a pile or the like by moving it generally normal to the longitudinal axis of the pile. Specifically, the apparatus comprises longitudinal frame members carrying at one end a driven blade and at the other end a stationary blade or anvil. The stationary blade is mounted on an end cross member, one end of which is pivotally secured to one of the longitudinal frame members and the other end of which is adapted for locking to the other of the members. By pivoting the end member carrying the stationary blade upwardly or out of the general plane of the frame, the device may be opened up so that it may be slipped about a piling or tree, without having to be lowered thereabout as has heretofore been required.
