BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a waste compacting device.

SUMMARY OF THE INVENTION An object of the present invention is to provide a waste compacting device and, more particularly, a transportable waste compacting device adaptable to fixed installations.

In accord with the invention, there is now provided a waste compacting asembly comprising an elongated housing comprised of a continuous wall of generally circular cross section having an inner surface, a movable compactor of circular cross section slidably mounted within said housing, said housing having an opening defined therein through which waste may be loaded for compaction therein, a portion of said housing being constructed in the form of a funnel, said compactor being forcibly reciprocable toward and away from said funnel to compact waste loaded into said housing against the inner surface of said funnel as said waste is moved therethrough by said compactor, shearing means acting in association with said compactor to prevent immobilization thereof by jamming of said waste,

BRIEF DESCRIPTION OF THE DRAWING Other objects and many of the attendant advantages of this invention will be readily appreciated as the same become better understood by reference to the following detailed description when considered in connection with the accompanying drawings, in which like reference numerals designate like parts throughout the Figures thereof, and wherein:

FIG. 1 is a perspective view of the inventive device;

FIG. 2 is a sectional view of the inventive device shown in FIG. 1;

FIG. 3 is an enlarged cross-sectional view of the compactor;

FIG. 4 is an enlarged cross-sectional view of the housing;

FIG. 5 is an enlarged cross-sectional view of the right end of the inventive device; and

FIG. 6 is an enlarged cross-sectional view similar to FIG. 5 showing the waste being loaded into a container.

DESCRIPTION OF THE SPECIFIC EMBODIMENTS Referring now to the drawings, wherein like reference characters designate like or corresponding parts throughout the several views, there is shown in FIGS. 1 and 2 a waste compacting assembly 10 which includes an elongated housing 11 having an inner surface and a movable compactor 12 slidably mounted within the housing. The housing 11 is provided with an opening 13 defined therein through which waste 14 may be loaded for compaction therein. A portion of the housing, generally indicated by the numeral 16, is seen to be constructed in the form of a funnel having its longitudinal axis oriented in the direction of motion of the compactor 12. The compactor is forcibly reciprocable toward and away from the funnel to compact waste loaded into the housing against the inner surface 15 of the funnel. The waste is compacted as it is moved through the housing 11 by the action of the compactor.

As shown in FIGS. 1 and 2, the movable compactor 12 is preferably an annular member which is advantageously of circular cross section constructed in a pistonlike form. The compactor comprises a headwall 20, a skirt wall 21, and a carrying means 22. The skirt wall is integrally connected to the headwall and extends horizontally therefrom and substantially normal thereto. It is seen that the skirt wall 21 is an annular extension of the peripheral configuration of the headwall 20. The

carrying means 22 may be a single elongated annular member having an internally threaded channel formed in one end thereof to threadably receive a drive shaft, and having the other end thereof integrally connected to the headwall, skirt wall, or both. The carrying means 22 is advantageously a plurality of elongated annular members 23, each having one end thereof integrally connected to the junction between the headwall 20 and skirt wall 21, and having the other ends thereof terminated together in a collar 24 having an internally threaded bore 25 formed therein to threadably receive a drive shaft 26.

As shown in FIGS. 1, 2 and 4, the elongated housing 11 is an annular conduit which is advantageously constructed from a rigid material. The housing is preferably a generally circular enclosure comprising a wall 30 having an inner surface 15 and an outer surface 18. The preferred embodiment of the enclosure includes a left end section 31, a right end section 32 of lesser diameter than the left, an an open-ended funnel-shaped section 16 extending intermediate the end sections and merging thereinto to form a reducing conduit section which brings the right end section into waste flow relation with the left. The longitudinal axis of the housing is preferably oriented horizontally, as shown in FIGS. 1, 2, and 4. The opening 13 for the ingress of waste is preferably formed in the left end section 31 of the enclosure wall 30. It should be understood that it is a feature of the invention to use a simple construction of generally circular cross section easily orientable so that the opening is positionable for side loading as well as top loading by rolling the housing over to the extent circumstances dictate. In the preferred embodiment, the opening 13 is shown vertically oriented since the majority of users are expected to so use the device. The compactor 12, as hereinbefore described, may be conveniently slidably mounted within the left end section 31 of the housing, as shown in FIGS. 1 and 2. In operation, the headwall of the compactor l2 reciprocates between a forward position 35 and a rearward position 36, said positions defining the length of travel of the compactor. It is a feature of the invention to provide a compactor skirt wall 21 which extends horizontally from the headwall a distance substantially equal to or greater than the maximum horizontal dimension of the opening 13. This feature prevents inadvertently loading waste into the end of the left end section remote from the headwall when the compactor is projected to the forward position thereof. The right end 32 of the compactor serves as a discharge conduit and supporting means for removable waste containers generally represented by the container 37. It is a feature of the invention to dimension the right end or discharge end 32 of the conduit to allow standard sizes of waste containers well known in the art to be slidably mounted thereon as shown in FIG. 5. It is a further feature to provide disposable bags to be used in place of standard-sized waste containers.

The container 37 is mounted on the outer surface of the housing and held in place by its inherent weight. Waste 14, forcibly moved through the funnel l6 and progressively compacted therein and thereby as it is forcibly moved therethrough, contacts the inner bottom surface of the container and forcibly moves the container from the housing as the container is simultaneously progressively filled with com pacted waste. When a container becomes full it will fall of its own weight from the discharge end of the funnel. whereupon an attendant may replace said container with another empty container by slidably mounting it on the discharge mouth 32.

It should be understood that the compactor 12 is adaptable to be cyclically moved from the rearward position 36 thereof to the forward position 35 thereof and returned therefrom to the rearward position 36 thereof by driving means 40 associated with the housing that are well known in the art. The driving means may include hydraulic driving means having a smooth-surfaced drive shaft associated therewith instead of preferred embodiment includes a reversible gear motor 41 having electrical terminals 42adapted to be energized by a source of current. The motor 41 includes a controlling means 43 for stopping, starting and automatically reversing the motor and a power takeoff adapter 44 operably associated with the motor gearing. The drive shaft 26 is operably connected to the power takeoff adapter to rotate said shaft in place.

One end of the drive shaft 26 has a threaded body portion 27 which threadably engages the internally threaded collar 24 of the compactor 12. The opposite end thereof is a smoothsurfaced body portion 28 endwise supported for rotation in place. A supporting member 45 having a bored collar 45A connected thereto is provided to support the opposite end 28 of the shaft. It is to be understood hat the shaft is joumaled for rotation in the bored collar 45A and endwise anchored therein for rotation in place by means well known in the art. The supporting member 45 may be conveniently mounted within the left end section 31 of the housing to give a finished appearance to the inventive device by means well known in the art. To support the motor 41 in place, mounting means are provided which preferably comprise a bracket 46 and a supporting arm 47. The bracket 46 is integrally connected to the motor 41 forming a platform therefor. One end 48 of the supporting arm is pivoted to the bracket 46 by means of a pivot pin 48a and the other end 49 thereof is anchored to the supporting member 45 by means well known in the art. The housing 11 is advantageously provided with a guide pin 11A connected thereto which slidably engages a keyway channel 11B formed in the compactor skirt wall 21. The pin 11A cooperates with the sides of the keyway 1113 to constrain the compactor from rotation in place when torque is imposed thereon by the rotating drive shaft.

A feature of the invention is to provide venting means shown in the drawing as an opening 33 in the left end section of the housing. It is understood of course that a vented cover may otherwise be provided at an additional expense. In any event, an opening 33 is provided to avoid air compression and airlock problems which might otherwise occur during operation of the compactor if the left end of the housing were to be enclosed without providing a vent therefor. As shown by the dashed-line depiction of a transporter 50 it is a feature of the invention to provide a transportable waste compactor assembly adaptable for various fixed installation schemes.

As shown in FIGS. 1 and 2 the waste compactor assembly is adaptable for fixed installation at the bottom of an incinerator chute 51. It is a feature of the invention to provide an adapter 52 intermediate the bottom of the incinerator chute 51 and the loading opening 13 in the compactor housing. Waste loaded into the incinerator chute through a plurality of loading openings generally represented by the covered opening 53 falls by force of gravity into the adapter 52 and is guided thereby from the incinerator chute 51 to the compactor opening 13 and therethrough into the housing 11. As shown in FIGS. 1 and 2 the adapter 52 is a hopper comprising an elongated funnel of substantially rectangular cross section. The hopper is endwise vertically oriented to form a continuation of the incinerator chute. The hopper 52 advantageously comprises a substantially vertical front wall 54, a slanted rear wall 55, and slanted opposing sidewalls 56. All of the walls 54, 55, and 56 are constructed from sheet material. The slanted walls 55 and 56 are connected together to form a waste guide chute. The opposing upwardly oriented edges 57 o the rear wall 55 are connected to the rearward upwardly oriented edges 58 of the opposing sidewalls 56 by means well known in the art. The forward vertically oriented sidewall edge surfaces 59 remote from the rear wall 55 are connected to the front wall 54 throughout the lower portions thereof by means well known in the art. The upper portions of these sidewall edges 59 abut against the incinerator brick work intermediate the front wall and the upper edges.

In the preferred embodiment, the front wall 54 extends around the compactor housing 11 to support the housing in comprising a pair of arcuate plates 63 and 64 edgewise orientable with respect to each other to define an arcuate shearing plane substantially equal to the width of the housing cutout 13 as measured along the circumference of the housing. The plates 63 and 64 shear refuse deposited partially within and without the waste compactor housing to prevent the waste from jamming between the compactor and housing when the compactor is moved to the forward position 35 thereof. The shearing means includes a first plate 63 connected to the compactor head 20 and a second plate 64 connected to the front wall of the hopper 52. In operation, the compactor moves one of the arcuate edge surfaces 65 of the first plate 63 slidably within one of the arcuate edge surfaces 66 of the second plate 64 to shear waste therebetween, thereby preventing immobilization of the compactor by jamming. The arcuate edge surfaces 65, 66 are brought into shearing relation with respect to each other when the compactor-carried plate 63 is moved into cooperating relationship with the front-wall-carried plate 64.

A feature of the invention is to provide a reinforcing strut 34 endwise connected to the skirt wall by means well know in the art. The strut comprises a channel member having an orifice 39 bored through the center thereof. The centrally located aperture 39 is assembled in register with the internally threaded collar 24. As shown in the Figures, the drive shaft 26 is insertable therethrough when it is threadably engaged with the collar. The strut is connected to the collar by means well known in the art.

Referring now to FIGS. 4, 5 and 6, it is seen that a switching means 70 may advantageously be provided to signal the motor-controlling means 43 to stop and start the motor 41 depending upon whether or not a container 37 is or is not mounted on the discharge end of the housing. The controlling means 43 may advantageously comprise a microswitch having a closed position 67 which corresponds to start signalling and an open position 68 which corresponds to stop signalling. The microswitch may advantageously have a lever arm 69 pivoted thereto to contact the inner surface of the container when it is mounted on the housing. The lever 69 is so positioned with respect to the microswitch that when a container is mounted on the funnel the lever is depressed by the container. In turn, the lever closes the switch, thereby signalling the motor to start cyclically compacting the waste. The lever is released when the container falls off or is otherwise removed from the housing. Thereupon the switch opens, thereby signalling the motor to stop cyclically compacting the waste.

Disinfectant dispensing means 71 may be conveniently located within the hopper to dispense disinfectant therein.

A warning alarm means 72 may be conveniently locate, as shown in FIG. 1, to respond to the stimulus of fire due to combustion within the hopper and/or basement area and emit a warning signal to the occupants of the house wherein the compactor is disposed.
