  • Patent number: 9579864
    Abstract: A solar-powered waste compactor comprises a waste container for housing waste, a compactor ram actuated by a hydraulic cylinder and piston assembly for compacting the waste in the waste container, and a hydraulic power unit operably associated with the hydraulic cylinder and piston assembly for powering the compactor ram. The hydraulic power unit comprises a motor/pump assembly including a pump unit, a single-phase electric motor driving the pump unit and a flow control valve operating the motor/pump assembly at first or second flow rate depending on an operating pressure. The hydraulic power unit further comprises a battery unit, a solar panel to charge the battery unit, a DC-to-AC inverter, a single-phase AC power inlet connectable to a source of a single-phase electrical power grid, and a reversing contactor providing the electric current only from the inverter or the power inlet at any given time.

  • Patent number: 5415086
    Abstract: A preferred embodiment includes first and second waste storage compartments for storing separately nonrecyclable and recyclable waste products. A compression member is operably associated with the first and second waste storage compartments for compressing waste material therein. The compression member includes a ram operably connected to a piston and cylinder assembly. The ram is displaced along a single directional path to compress waste material in both the first and second waste storage compartments. An adjustable member is operably associated with the first and second waste storage compartments for varying the storage capacity thereof. The adjustment member includes a baffle extending substantially the length of the first and second waste storage compartments. The baffle is hingedly connected to a support member. Upper and lower doors are associated with each of the first and second storage compartments.

  • 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. A support defines a portion of the bottom of the compaction chamber. The support is reciprocable transverse to the first cylinder and piston assembly and is aligned with the door for moving compacted material through the opening.

  • Patent number: 5297481
    Abstract: A system for compacting and storing separately recyclable and nonrecyclable waste materials. The system includes two separate storage and compacting units, one of which is designated for the storage of recyclable material and the other designated for the storage of nonrecyclable material. The system further includes a rack structure having a substantially horizontally extending platform and a plurality of support legs extending downwardly from the substantially horizontally extending platform. The support legs and platform form a passageway or channel for receiving at least a portion of one storage and compacting unit. The other storage and compacting unit is mounted on the substantially horizontally extending platform of the rack directly above the first compacting and storage unit.

  • Patent number: 5044271
    Abstract: An improved manually fed waste baling compactor has a single interlock switch which controls movement of a vertically oriented ram and platen such that the ram cannot move unless both a chamber door and a guard door of the mechanism are properly positioned. A magnetic interlock prevents opening the guard door manually until after the compression and retraction stroke of the ram.

  • Patent number: 4817520
    Abstract: An offset compactor assembly includes an elongated chamber having a waste receiving end portion and a waste discharge end. A ram is displaceable therein for causing compaction of waste during transfer therebetween. A first cylinder and piston assembly is operably connected to the ram for causing displacement thereof. A gate is positioned proximate said end and is movable into and out of said chamber for selectively restricting said chamber and thereby controlling the passage of waste therethrough. A second cylinder and piston assembly is operably connected to the gate for causing displacement thereof. An hydraulic control operably interconnects the first and second cylinder and piston assemblies for causing offsetting operation thereof so that the waste compacted in the chamber has a substantially uniform density.

  • Patent number: 4811660
    Abstract: A mechanical lock-in device for a front loader compaction assembly to prevent relative movement of the refuse container with respect to the stationary compactor head and support. The lock-in device includes a lock-in bracket fixed to the compactor head support, and a locking member movably mounted on the refuse container adjacent one of the horizontally extending side pockets which are engaged by lifting forks of a collection vehicle for dumping. The lower portion of the locking member engages the lock-in bracket to prevent relative movement of the refuse container while in use. When it is desired to dump the container, when the lifting fork of the collection vehicle is inserted into a container side pocket, it engages a portion of the locking member which extends transversely of the pocket, thereby effecting an upward movement of the locking member out of engagement with the lock-in bracket to permit the container to be moved from its position beneath the stationary head.

  • Patent number: 4741455
    Abstract: A bustle gate pivot mechanism includes a multisided container. A first seal is disposed about a first end portion of the container. A first pivot mechanism is connected to a first one of the sides and includes a first link extending therefrom and pivotally connected thereto. A second pivot mechanism is connected to the first link at a distance from the first pivot mechanism and is pivotal therewith and includes a second link extending therefrom and pivotally connected thereto. A bustle gate is connected to the second link at a distance from the second pivot mechanism and is pivotal therewith. A second seal is disposed about the gate. The gate is pivotal about the second pivot mechanism for selectingly engaging and disengaging the first and second seals. The gate and the first link are furthermore pivotal about the first pivot mechanism for selectively positioning the gate proximate to and remote from the first end portion.
