Abstract

A kitchen compactor for the crushing of trash and other disposable wastes is disclosed. The compactor employs a hydraulic cylinder and piston assembly which is controlled by a control means that causes water from the household water supply to flow into the hydraulic cylinder. The water pressure produces motion of the piston which activates a lever arm upon which a pressing platen is mounted. The movement of the lever arm causes the pressing platen to enter into or withdraw from a waste container. When the pressing platen enters the waste container, the waste contained therein is compressed into a small bale or package of considerably smaller volume for easier disposal.

ATTORNEYS.
KITCHEN COMPACTOR The present invention is in the field of solid waste disposal and particularly in the field of solid waste disposal by compressing the waste into a small volume of space.
In the field of solid wastedisposal, the most common contemporary method of such disposal is through trash collection. In the normal household or apartment, the residents will deposit their disposable wastes in wastebaskets throughout the dwelling. Periodically, these wastes are collected in garbage pails which are later emptied into garbage collection trucks. Once the trash is placed into the trash collection truck, the trash is usually compressed by a compression apparatus built into the truck itself. This compression makes the trash collection process more efficient because trash, as a general rule, is comprised of a mixture of many objects which do not comprise a dense mass. By compression, the density of the trash collected can be increased which allows the trash collection truck to carry more trash than would be possible without compression.
The problem of trash density is not unique to the trash collection truck because it is desirable even within the household to compress collected trash into a smaller volume to conserve storage space requirements. A disposable bottle, for example, occupies a considerable space into which other objects could be placed if the bottle were crushed. The same decrease of trash density can also be achieved by the crushing of plastic containers, tin cans, aluminum cans, cardboard containers and other crushable packages. A further reason for the desirability of crushing trash within the household is that the trash can be collected in fewer trash containers and transported to the trash collection trucks more quickly and easily. v
In light of the foregoing it is a primary object of this invention to provide an apparatus particularly suited for use in the kitchen for compressing trash.
It is a further object of this invention to provide a trash compression apparatus which is physically suitably for installation in kitchens.
It is another object of this invention to provide a trash compressor apparatus having operating means which is operative from the household water supply for providing the compressing force.
Other objects, advantages and salient features of the present invention will become apparent from the following detailed description, which, taken in conjunction with the annexed drawings, discloses a preferred embodiment thereof.
The foregoing objects of the present invention are achieved by the simple kitchen compactor of the present invention. A water activated hydraulic cylinder is mounted within the compactor unit. A control means is provided to control the flow of water from the household water supply into the hydraulic cylinder. The piston contained within the hydraulic cylinder is activated by the water supply and it causes the attached piston rod to project out of or retract into the cylinder body. The movement of the piston is transmitted by a lever arm to a pressing platen which is movable into or out of a trash container. When the container is filled with trash and the platen enters the container, the contents of the container are compressed. Once the trash container becomes full, the front of the kitchen compactor is opened and the compacted waste is removed.
Referring now to the drawings which form a portion of the original disclosure:
FIG. 1 is a perspective view of the kitchen compactor of the present invention;
FIG. 2 is a sectional view taken along line 2-2 of FIG. 1;
FIG. 3 is a sectional view taken along line 3-3 of FIG. 2; and I FIG. 4 is a fragmentary elevational view showing the sliding platform partially withdrawn from the housing of the compactor.
Referring now to the drawings in further detail, there is illustrated in FIG. 1 a kitchen compactor generally designated 1. The compactor includes a housing or casing having a front wall 3, a pair of opposed side walls 5 and a top wall 7. A control button 2, the purpose of which will be described hereinafter, is mounted on one of the side walls 5. A handle 6 is centrally attached at the lower portion of the front wall 3. Above the handle 6, there is provided a hopper door 8 which serves to close an opening 9 in the front wall 3. The hopper door 8 is pivotally attached at its lower end by a hinge 10 which connects the hopper door 'to the front wall. A handle 4 attached to the hopper door 8 permits opening and closing thereof.
Referring to FIG. 2, it can be seen that the compactor casing also includes a rear wall 12 which carries at its lower end, a projecting wall portion 18 which extends into the casing interior to act as a stop for a movable platform means generally designated 14. The platform means 14 includes a bottom or base wall 16 having an outer end engaged to the bottom of the front wall 3 and having an inner end engageable against the wall portion 18. Slide members 20 are attached near the top of front wall 3 along the opposite sides thereof and are generally perpendicular to front wall 3. Each slide member 20 is engageable with a cooperating track 22 attached to the inside of the side walls 5. Roller means 23 permit the slide and track members to move relative to one another when the handle 6 is pulled to move the platform means 14 inwardly or outwardly. When slide member 20 is in the position shown in FIG. 2, the rear edge thereof contacts stop means 24 on the inside of the back wall 12 to insure that front wall 3 and moving platform 16 are in proper alignment with the remaining parts of the compactor.
Hopper door 8 has a top flange 26 which butts against stop 28 when hopper door 8 is in its closed position as shown in FIG. 2. The hopper door 8 also has two opposed parallel side flanges 30 attached thereto, each side flange being perpendicular to the plane of hopper door 8 and the plane of top flange 26. Side flanges 30 are spaced apart and positioned on opposite edges of hopper door 8 and form a chute for trash when the hopper door 8 is swung to its open position as shown in FIG. 4, by pulling the handle 4. Each hopper door side flange 30 has a lateral flange 32 which engages front wall 3 when hopper door 8 is in its open position.
Returning now to FIG. 2, rear wall 12 has a rigid support member 34 attached interiorly thereof and occupying a position extending from the bottom of rear wall 12 to a point near the top of rear wall 12. A pair of lever arm support members 36 are rigidly attached to support member 34, each lever arm support member 36 being substantially a planar surface said members 3 being positioned in spaced parallel planes perpendicular to the plane of support member 34.
The wall portion 18 at the bottom rear of the unit into pipe 76 which connects-directly to hydraulic conalso serves as a hydraulic cylinder support means and can be attached to the support member 34 or directly to the rear wall 12. The ,wall 18 supports hydraulic cylinder and piston assembly 38 by a pivotal connection 40. Hydraulic assembly 38 has a piston rod which carries a clevis 42 being pivotally attached at pivot connection 44 to lever means 46. Lever means 46 has a pivotal connection 48 about rigid rod 50 which passes through lever means 46 substantially perpendicular to the plane thereof and is rigidly connected to suitable support members 36 at either end.
Lever means 46 has a pressing platen 52 attached thereto, said pressing platen having a pair of support arms 54 mounted on opposite sides thereof, with each support arm having a guide rod 56 projecting therefrom. Each guide rod projects from its connection point with its attached support arm 54 towards the side wall 5 of the compactor and intersects and slides within a groove 58 of a guide 60 mounted on the inside of the side wall 5.
Disposed below pressing platen 52 is a trash container 62 which is supported on base wall 16 of movable platform means 14. Lever means 46 and pressing platen 52 are constructed with notch or slot 66 which is designed to partially pass over the top edge 68 at the rear of trash container 62 when lever means 46 is moved into the position shown in FIG. 2 in dotted lines.
The general operation of the compactor as shown in FIG. 2 requires that a certain amount of trash be placed into trash container 62. Upon activation of switch 2, the hydraulic power means control, to be described later, activates hydraulic cylinder 38 and causes piston rod and clevis 42 to extend from hydraulic cylinder 38. The movement of the clevis 42 causes lever means 46 to rotate about pivotal connection 48 and cause pressing platen 52 to move downwardly through the open top of trash container 62 and compress the trash contained within the trash container 62. The hydraulic power control means subsequentlyfunctions to cause piston rod and clevis 42 to withdraw and return to its original position as shown in solid lines in FIG. 2. The movement thus imparted to pressing platen 52 serves to compress any trash contained with trash container 62. When trash container 62 becomes filled with compacted trash, the front wall 3 and connected movable platform means 14 can be withdrawn from the compactor because movable platform means 14 is supported upon floor 69 by a plurality of floor-engaging rollers 71!. In FIG. 4, movable platform means 14 is shown partially withdrawn from the compactor and it can be readily discerned that the platform can be moved a sufficient distance to allow trash container 62 to be lifted vertically off of movable platform 16 to allow the compacted trash to be removed.
Referring now to FIG. 3, water pipe 72 connects directly to the domestic water supply for the building in which the kitchen compactor is to be installed. Valve 74 is installed at the end of water pipe 72 in order to isolate the kitchen compactor from the domestic water supply when maintenance or repairs are necessary upon the hydraulic apparatus within the kitchen compactor. The water that passes through valve 74 passes trol means 78 which is activated by control button 2. Hydraulic control means 78 connects via pipe means 80 to hydraulic assembly 38 and further connects to drain means 82.
Hydraulic control means 78 in response to signals received from control button 2 causes water to enter hydraulic assembly 38 through pipe means 80. The water entering the cylinder of the hydraulic assembly 38 acts to force the piston and the piston rod, which carries clevis 42, out of the hydraulic cylinder, thus pivoting the lever arm 46 and causing pressing platen 52 to enter trash container 62. The water within hydraulic cylinder which is located in the chamber above the piston escape through pipe means 80 and into drain 82 which connects to the sewage system of the building in which the compactor is installed. After piston and piston rod have been fully extended from the hydraulic cylinder, hydraulic control means 78 causes water to pass through pipe means 80 into hydraulic cylinder and cause piston and piston rod to retract within the hydraulic cylinder with the excess water escaping through pipe means 80 and into drain 82.
Because of the small size and shape of the compactor 1, it is adapted for ready installation in a kitchen, either beneath a counter or in lieu of a cabinet. The water supply for the compactor can be connected with the kitchen sink water supply, without requiring any extensive plumbing modifications in the kitchen. Obviously, if desired, the cylinder and piston assembly can also be energized by some fluid power source other than water. In use, the handle 4 is pulled to open the hopper door 8 and trash is deposited through opening 9 and into the trash container 62. Once the door 8 is closed, the button 2 can be operated to cause the trash to be compressed within the container 62 by the pressing platen 52.
After reading the foregoing detailed description, it should be apparent that the objects set forth in the outset hereof have been successfully achieved by. the present invention. It will be apparent, however, that certain modifications may easily be made by those of skill in the art without avoiding the spirit and scope of the invention as set forth in the appended claims.
