While these trash compactors may be suitable for the purposes for which they were designed, they would not be as suitable for the purposes of the present invention, as hereinafter described.
A domestic refuse compactor including a receptacle in which household refuse is compacted by a ram to a fraction of its former volume. The ram is operated to compact the refuse with a preselected maximum force by means of a pair of axially fixed rotatable screws axially driving a pair of nuts threadedly mounted thereon. The nuts are yieldably connected to the ram through a corresponding pair of coil springs coaxially about the respective screws. Switches are provided responding to a preselected contraction of the springs corresponding to the preselected maximum force to stop the compaction operation of the ram and cause the ram to be moved reversely to a retracted position completing the compacting operation.
A refuse compactor has an upright housing whose internal compacting chamber is accessible by a door provided in its circumferential wall. A compacting head fills the cross section of the chamber and is guidedly slidable in axial direction thereof. A power source and motion-transmitting arrangement are provided for advancing the compacting head towards an end wall of the housing to thereby compact refuse between the end wall and the compacting head, and for subsequently withdrawing the compacting head in direction away from the one end wall for enabling removal of the compacted refuse.
A garbage and refuse disposing unit is disclosed herein. The unit includes a housing for receiving refuse of all types, a compressor mechanism for compressing the refuse and freezing means for freezing the compressed refuse into dense or solid pellet-like units.
A housing is provided with an internal chamber adapted to accommodate refuse to be compacted. A plunger is mounted in the chamber and is movable from a rest position at one end of the chamber to an advanced position adjacent the other end of the chamber and in which position refuse in the chamber is compacted, and back to its retracted rest position. Operating means is provided for automatically cycling the displacement of the plunger from and to its retracted rest positions. Initiating means is associated with the operating means for initiating the operation of the same.
A refuse compactor comprising a housing, a main compacting member and an auxiliary compacting member slidably displaceable inside the housing, and a single hydraulic actuating unit connected to both compacting members and including a pair of hydraulic pistons concentrically mounted and arranged to cause to and fro displacement of the compacting members relative to each other and to the housing. The proposed single actuating unit results in a compactor having a relatively slender and effectively compacting shape requiring only a simple hydraulic control. Cooperating teeth are attached to the housing and to the main compacting member to shear the refuse arriving from a hopper and a guide is cooperatively associated to the main compacting member to maintain the teeth in a proper angular relationship.
In a trash compactor which includes a ram for compacting waste materials deposited in the compactor, a two-piece, reusable liner is positioned within the compactor to receive the waste material and facilitate removal of the waste material after compaction thereof. Each of the sections is formed of a fairly rigid material, such as polyethylene, and each is provided on its outer surfaces with ribs which serve to both strengthen the liner sections and prevent the liner from sticking to the interior surfaces of the drawer. Each of these sections is constructed of integrally formed, upstanding sidewalls and a bottom wall with one side wall of each of the sections being just high enough to retain liquids within the liner while permitting their ready assembly and disassembly.
A garbage compactor has a rigid frame structure with a lower horizontal base plate, an upper horizontal top plate connected by three interconnecting vertical bars. An octagonal container positioned between the base plate and top plate is pivotally connected to and slidable on one of the interconnecting bars to swing outwardly for loading and unloading with a hydraulic cylinder on the top plate operating to compress garbage in the container. A hinged wall section of the container is operable to permit removal of a bag insert when filled with compacted garbage.
A trash compactor using a dolly as a receptacle for the trash to be compacted. The dolly is normally spring supported ready for movement into and out of the compactor, but when in the compactor and subjected to compacting pressure, the dolly is pressed downwardly, upon the beams of the main compactor frame which then takes the full compacting pressures. A novel construction of the dolly and compactor floor of the main frame makes such transfer of load possible. The compacting pressure is developed by four hydraulic cylinders, all of which are mounted on a common plate. The rod ends of the two center cylinders are connected to the top member of the main frame and the cylinder ends are connected to the common plate. The rod ends of the remaining two cylinders are connected to the main compacting plate with the cylinder ends mounted on the common plate. With the four cylinders mounted in this manner, twice the movement of the compacting ram is obtained. Safety devices include a deflection switch actuated when a deflection exceeding a given amount takes place within the frame assembly. Such deflection may be caused by solid materials, such as logs, bricks, etc., inadvertently placed in the material to be compacted. Under normal conditions, the cylinders will reverse and the unit will automatically stop once the cylinders reach the limit of their upward stroke. A magnetic switch and latch operated switches serves to prevent operation of the ram unless the trash loading door and dolly are in the closed and latched position.
A small portable housing forms a trash compacting chamber in the bottom. At one side of the housing interior, above the chamber, is a space through which trash can fall to the chamber from an upper trash compacting opening. At the other side of the interior of the housing and above the chamber is the compacting mechanism powered by a hydraulic ram. This mechanism includes a carriage supporting a two-part platen, one part of which is below the ram and fixed to the carriage and the other part of which is articulated for movement between a vertical position when raised, and a generally horizontal position across said space when being lowered. Several lost motion mechanisms are disclosed for initially so moving the articulated portion as the ram is extended and thereafter providing carriage movement. A gate is mounted to swing across the space when the platens are lowered so as to catch any trash introduced at that time. A counter is actuated by the opening of a door at the access opening and after a plurality of actuations initiates a compaction cycle. As an alternative to the counter, a timer is employed to cycle the compactor periodically.
A piston/cylinder type element particularly suited for embodiment in a refuse compactor as the ram thereof comprises adjustable guide means for guiding the piston-like element in sliding movement within the cylinder. The guide means are adjustable to accommodate wear in the mating surfaces thereof. There is also disclosed a discharge cone for a compactor which is releasably secured to the ramhousing structure in a selected one of a plurality of positions evenly to distribute wear on the cone produced by the passage of refuse therethrough and that cone is removable from the ram housing to be replaced by a different structure, depending upon the refuse to be compacted. Additionally, the ram member of a compactor includes novel teeth elements to cut through refuse which might otherwise be wedged between adjacent surfaces of the ram and cylinder and cause jamming.
In a refuse compactor wherein refuse in a disposable bag within a receptacle is compacted by a ram driven by a reversible electric motor, a “full bag” indicator lamp is energized when the refuse compacted in the receptacle is at a predetermined level. The motor drives the ram downward into the receptacle to compact the refuse, and when the ram slows in response to the reactive load of the refuse, a centrifugal switch reverses the direction of the motor to return the ram to a rest position above the receptacle. The bag is diagnosed full to energize the indicator lamp if the ram is at a predetermined level in the receptacle when the motor reverses. The indicator lamp is controlled by a latching relay that requires only one pair of contacts to energize and latch on the lamp.
A portable refuse compactor has a mobile compression frame including a base in the general shape of a “T”. a trash bin bottom engagement surface on the trunk of the “T” provides a purchase point against which compacting takes place. Compacting platen is positioned above, and moveable with respect to the bin bottom engagement surface. Hydraulic ram displace platen toward the bin bottom engagement surface.

The portable trash compactor 10 is shown installed in the dashboard 70 of a vehicle. The method by which the inner compartment is accessed in this embodiment differs from that described above. The dashboard version includes a hinged chamber door 72, similar to the access door 16, for gaining access to the refuse in the refuse bin. After the refuse has been compacted, the user selectively opens the hinged chamber door 72 and removes the refuse bin from the inner compartment 40. Upon disposing of the compacted refuse, the hinged chamber door 72 is opened once again and the refuse bin 42 is replaced within the compartment 40 if the inner housing 14. Thereafter, the refuse bin is able to receive additional refuse.
The housing lock sensor 68 determines whether the outer housing 12 is in a first open position or in a second closed position. Upon detecting the outer housing 12 is in an second closed position, the housing lock sensor signals the processor 80 to lock the housing lock thereby securing the outer housing 12 to the inner housing 14. When the outer housing 12 is in the second closed position, a user can selectively dispose of refuse through the access door 16. When the access door 16 is in an open position, the access door sensor 86 signals the processor 80 and prevents operation of the portable trash compactor 10. Upon the access door sensor 86 detecting that the access door 16 is in the closed position, the sensor 86 is disabled and operation of the device is permitted.
When a user desires to compact the refuse that has collected in the refuse bin 42, the user depresses the operation button 26. Thereafter, the processor signals the motor 52 to operate in a first direction thereby causing the drive member 56 to extend and cause the ram to exert pressure on the refuse in the refuse bin 42. The pressure sensor 84 determines the amount of pressure being exerted upon the refuse and upon the amount reaching a threshold value, the pressure sensor 84 signals the processor to cause the motor 52 to operate in a second direction thereby retracting the ram 54 and the drive member 56. Upon full retraction of the drive member 56, the processor signals the motor to stop operating and thus allowing the user to dispose of the compacted refuse.
