  • Patent number: 7878432
    Abstract: A plunger can for a roller assembly within a pulverizing mill has a body which contains a compression spring. A stub shaft transfers the force generated by the compression spring to the roller assembly. A bushing in cooperation with a locking guide in the fore end of the plunger can, along with the stub shaft in an aft end of the plunger can, contains the compression spring there between. The locking guide has an annular flange that fits within an annular channel within the plunger can body. A plurality of extensions spaced around an outside perimeter of the annular flange cooperates with a plurality of extensions around an inside perimeter of the plunger can body such that both sets of extensions clear each other when the locking guide is inserted into the plunger can body. When rotated, the sets of extensions are aligned with each, forming a mechanical lock.

  • Patent number: 7871028
    Abstract: A chopper unit for chopping bales of vegetation is particularly well suited for chopping large square bales. The chopper unit mounts on the arms of a transporter unit such as a skid loader. The unit includes a housing having a deck with a window therein. During normal operation, the deck faces upwardly. The housing includes a chopping chamber having the window in the deck at one end thereof, and extending to an opening or window in a side wall of the housing. A bale hopper mounted on the deck can translate along a predetermined path. The bale hopper extends generally upwardly when the unit is in an operating position, and surrounds the window in the deck. A vegetation cutter mounted within the chopping chamber partially projects through the deck's window and into the hopper. Rotating the cutter chops the vegetation into small pieces. The hopper translation allows the cutter to access the entire bottom surface of the bale.

  • Patent number: 7850106
    Abstract: A shredder is disclosed. The shredder has an external frame, and includes an internal waste container space that has an upper primary waste container, and a lower secondary waste container, all positioned beneath a shredder mechanism that includes a motor and cutter elements. The shredder mechanism is positioned so that shredded waste falls into the primary waste container. In the event that waste falls outside the primary waste container, due to the primary waste container being full or for other reasons, the waste can be caught in the lower secondary waste container. A sweep mounted to the bottom of the primary waste container in some variations can push or pull shredded waste into the secondary waste container as the primary waste container is removed from the external frame in a generally horizontal direction. The secondary waste container may also include a handle to facilitate removal in some variations. Other variations and improvements to shredders are also disclosed.

  • Patent number: 7828235
    Abstract: The present invention is generally related to an apparatus having cutter elements for destroying articles such as paper sheets and a mechanism for advancing at least a top sheet from a stack of paper in a tray into the cutter elements for shredding. In one embodiment, the apparatus uses a rotatable feed roller to feed paper atop the stack to the cutter elements. The feed roller moves in an alternating manner between a lowered and raised position to engage and disengage the stack when advancing the paper therethrough. Alternatively, a rotatable cam may be used. In an embodiment, the apparatus uses a rotatable drum or rotatable belt with an internal vacuum to lift paper from the stack and feed into the shredder mechanism.

  • Patent number: 7823813
    Abstract: A control mechanism for the feed of a brush chipper is disclosed. A lower feed stop bar, located under a feed table, pivots on a pivot axis located below and toward the brush chipper from the control bar of the lower feed stop bar. The center of gravity of the lower feed stop bar, then, tends to pivot the lower feed stop bar away from the feed disengage position. Hence, nuisance trips due to vibration, impact of brush on the table, etc., are reduced.
