  • Patent number: 7690296
    Abstract: A method and associated apparatus designed to effectively twist and cut baling wire during the baling process. The apparatus includes a twister assembly that has a plurality of gear-driven twister heads. During the baling process the twister assembly extends from a slide housing so that the twister heads engage and twist adjacent strands of baling wire. The twister assembly then retracts back into the slide housing so that the twisted portion of the baling wire is cut by a cutting assembly attached to the slide housing.

  • Patent number: 6427585
    Abstract: A compaction and transfer apparatus adapted to measure the length and/or weight of a waste log during compaction and transfer thereof, is provided. The apparatus comprises a compaction chamber, a closure device, a compaction ram, and a movement and/or weight detector. The compaction chamber is adapted to receive waste material. The compaction chamber has a discharge opening. The closure device is selectively movable into and out of the discharge opening to control the size of the discharge opening. The compaction ram is movable through the chamber to press the waste material against the closure device and thereby provide compaction of the waste material. The movement detector preferably is mounted on the closure device. The movement detector is adapted to detect movement of the waste material through the discharge opening, which movement corresponds to the length of the waste log extending out of the discharge opening.

  • Patent number: 6068440
    Abstract: A locking mechanism is provided for a roll-off container hoist. The locking mechanism secures a roll-off container to the roll-off container hoist when the hoist is in a transport orientation and releases the roll-off container when the hoist is moved from the transport orientation toward a hoisting orientation. Also provided is a container hoist which includes such a locking mechanism, as well as a vehicle which carries a locking-mechanism-equipped container hoist. A method of using the container hoist likewise is provided. Preferably, the locking mechanism requires no springs or other resilient actuators and instead is freely actuated by gravity in one direction and by engagement with a preferably rigid actuating surface in an opposite direction. The locking mechanism includes a movable plate and a guide for the movable plate. The movable plate is freely movable through the guide, from a locking position to an unlocking position and vice versa.

  • Patent number: 5746378
    Abstract: A volume reduction machine for crushing beverage containers has a pair of feed rolls and a pair of crusher rolls. The feed rolls in spaced relationship to a feed plate, urge containers to be crushed, while puncturing them. The feed rolls comprise a plurality of spaced feed discs and are aligned to overlap to ensure self cleaning. The crusher rolls comprise a plurality of closely-spaced discs. Spaces between discs slightly exceeding the thickness of the disc. The crusher rolls are offset such that the discs of one roll align with the spaces between discs of the other roll. The crusher rolls have an adjustable gap and are aligned with a lower edge of the feed plate. The discs forming the crusher rolls include circumferential notches of a given size and shape to deform plastic beverage containers beyond their modulus of elasticity thereby overcoming the problem of such containers springing back after crushing. An oscillating horizontal bar provides a debridging dejamming feature to the machine.

  • Patent number: 5575201
    Abstract: A compactor assembly comprises a ground supported housing having an open top through which waste material is deposited. An auger is rotatable on an axis positioned within the housing for breaking waste material received therein through the open top, and for transporting the waste material therethrough. A drop area is downstream of the receiving chamber of the housing and has a remote open portion. A compactor ram is reciprocal on an axis parallel to the auger axis for transferring waste material through the open portion. A first drive is operably associated with the auger for rotating the auger, and a second drive is operably associated with the compactor ram for causing reciprocation thereof.

  • Patent number: 5353698
    Abstract: A horizontal baler has a longitudinally extending generally rectangular frame assembly defining a receiving chamber and an adjacent aligned compaction chamber. Each of the chambers has a top, a bottom, and sides. A ram is mounted for reciprocation within the receiving chamber so that material therein may be transferred to the compaction chamber and compacted therein by reciprocation thereof. A first cylinder and piston assembly is longitudinally disposed within the frame assembly and is operably associated with the ram for causing reciprocation thereof. A door defines one of the sides of the compaction chamber. The door is selectively securable and movable relative to an opening communicating with the compaction chamber.

  • Patent number: 5330307
    Abstract: A container for compacting refuse is provided. The compacting container is mounted transversely to the elongated bed of a refuse collection vehicle. Refuse is deposited into the compacting container through a first refuse inlet located in a first end of the compacting container along one side of the truck and through a second refuse inlet located in the top of the compacting container via a pivotally mounted basket located on the second end of the container and which is operated by a hydraulic or pneumatic cylinder. The compacting container is discharged through a pivotally mounted door located on the same end of the container as the basket. An automatic latch keeps the door closed during compaction of the refuse.

  • Patent number: 5299142
    Abstract: A method of determining the fullness of a compactor having a reciprocating ram and a container includes the steps of setting a target for the number of reciprocations of the ram required to fill the container to a preselected partial fullness. Each reciprocation of the ram is monitored and the total number is summed. The total number of reciprocations is compared to the target number, and the percentage fullness is calculated from those numbers. The percentage fullness is then displayed locally.
