Description
10~ 43 BACKGROUND OF THE INVENTION
This invention relates to apparatus for collecting and compacting waste material. More particularly, this invention relates to apparatus for collecting and compacting waste material such as household garbage, trash or the like within a container operable to be carried by a motorized vehicle.
In the past the task of residential trash collection has been typically performed by a team of two or three men utilizing a rear loading container mounted upon a truck chassis.
One type of previously known trash container may be generally described as being rectangular in cross section and fixedly mounted upon a truck chassis. A charging or loading trough is fashioned at the rear of the container to receive loose trash or pliable containers such as trash bags and the like. A hydraulically actuated gate is then designed to engulf the waste material deposited within the loading trough and scoop or push the material into the container for compaction against the front end wall thereof.
Another type of previously known apparatus entails a trash container which is circular in cross section and rotatably mounted upon a truck chassis. Of the rotatably mounted containers, one design which exhibits considerable appeal is disclosed in a United States Patent No. 3,559,795 of common assignment with the subject application. In this patent a charging opening at the rear end of the container is disclosed with a shell-shaped baffle disposed inwardly of the opening.
Refuse or solid waste material is introduced through the opening and falls downwardly into a space defined by the shell-shaped member and the container end wall. A series of B ~
1` ~06704;~
ribs or flanges are mounted upon the interior of the container wall and upon rotation of the container serve to lift refuse introd~ced into said opening up and around the shell-shaped member. The refuse then falls downwardly onto the shell-shaped member, which, due to its configuration, deflects and directs the materials toward the closed end of the container. Although such a rotatable container exhibits many advantages one disad-vantage is that the shell-shaped member is subject to frictional wear as waste is loaded into the container.
A siynificant step in prolonging the operating life of rotatable waste material containers is disclosed in United States Patent No. 3,990,590 also of common assignment with the subject application. In this structure the shell-shaped member is replaced with a freely rotatable discoid element. As waste material is lifted over the end wall and into the container it falls downwardly o~to the discoid element which imparts a rotational movement ther~to. Such rotational movement minimizes frictional contact between the solid waste materials and the end wall. In addition to the discoid element this application discloses a helical vane or screw affixed along the interior surface of the container. Upon rotation of the container waste material therein tends to be translated toward the forward, closed end thereof.
Although waste material containers, such as previously described, are highly useful and exhibit marked advancements in the state of the art, room for further improvement remains. More specifically it would be highly ~0670~3 desirable to provide apparatus for collecting and compacting waste material which will reduce the number of cycles to a central dumping area and thus increase the efficiency and decrease the cost of a collection operation. In a similar vein, it would be desirable to provide apparatus for collecting and compacting waste material which will retain the advantages of the previously described devices while reducing inter-stitial voids within the waste material as the container is packed out.
It would also be desirable to provide apparatus for collecting and compacting waste material which would facilitate loading and use by operators. Further, it would be desirable to provide apparatus for collecting and compacting waste material operable to reduce large items as said items are deposited within said collecting apparatus.

. DETAILED DESCRIPTION
Referring now to the drawings and particularly FIGURE 1, there will be seen an axonometric view of a motor vehicle 10 operably carrying a collection and compacting apparatus 12 ` 1n accordance with a perferred embodiment of the invention.
The motor vehicle 10 is generally of a conventional design but includes a cab 12 with a permanently open right hand door frame 16 such that an operator or an operator's ; assistant may facilely alight to pick up trash etc. along a curb. The vehicle 10 further includes a chassis 18 comprising a pair of channel beams 20 and 22, note FIGURE 3 which extended rearwardly from the cab and longitudinally beneath the apparatus for collecting and compacting waste material 12.
~pparatus 12 is mounted upon chassis 18 for rotation - about the central longitudinal axis thereof through the provision of at least a pair of cradle rollers 24 and 26 which in turn are journaled on the channels 20 and 22 respectively. In this connection, although FIGURE 2 merely depicts one set of cradle roller pairs other roller sets may be carried by the chassis in longitudinally spaced relation throughout the length of the container.
Selective rotation for the apparatus 12 may be achieved with a perimeter applied rim gear 28 and pinion 30 combination ~hich may be hydraulically or electrically driven via drive shaft 32. Alternatively, rotational motion may be imparted to the apparatus 12 through the provision of a chain and sprocket arrangement as is well known in the art.
The foregoing motor vehicle structure, as previously nentioned, is intended to be a generally conventional design of the type which may be procurred from motor vehicle companies.
~nce the motor vehicle is purchased it may then be fitted with . 3 waste material collection and compacting apparatus 12 in accordance with the subject invention.
The subject invention entails a generally hollow -ylindrical container body 40 having an end wall 42 and 44 positioned across the forward and rear end thereof respectively.
rhe end walls are each mounted upon the motor vehicle chassis 18 and remain stationary while the container body 40 is mounted ~or rotational movemen~ upon the chassis 18 as previously describ-~d. Moreover the rearward end wall 44 is pivotally mounted as at 48 to a chassis carried yoke 50. This pivotal mounting arrangement permits the end wall 44 to be swung upwardly and ~pen to disgorge compacted trash from within the container at a central dump or land fill area.
Unlike previously known compacting and collecting ~ylinders the subject apparatus 12 is fitted at each end with a charging means including aperatures 50 and 52 and waste material receiving zones 54 and 56 fashioned within the forward end wall 42 and rearward end wall 44 respectively.
1007~4;~
At the rearward end wall 44 the cylinder 40 is provided with a plurality of longitudinally extending peripherally spaced packing vanes 60 note FIGURE 3. Packing vanes 60 serve to engage waste material deposited within the receiving zone 56 and lift the waste material into the interior of the cylinder 40 upon rotation thereof.
The rearward end wall 44 carries a cantilevered member 62 which semiconically projects inwardly therefrom in a posture longitudinally displaced from but blocking the opening 52.
The member 62 is fashioned with a recess 64 within the right ~ side~thereof, as viewed in FIGURE 3, which forms in cooperation ,~ with the end wall 44 and packing vanes 60 an opening to receive waste material deposited within receiving zone 56. In this connection as the cylinder 40 is rotated in a counterclockwise directionj,as viewed in FIGURE 3, waste material will be lifted upwardly by packing vanes 60 passed recess 64 and into the con-~, tainer 4~
The left hand side of the member 62 is closed andterminates with an edge surface 68 toward the bottom of the ~, 20 container. The semiconical wall of member 62 on the left side ~, thereof prevents waste material lifted into the container from , falling back into the receiving zone 56.
`~ The waste material after being lifted into the container generally falls onto a rotatably mounted, arcuate discoid element 70. The discoid element 70 is circular and mounted upon the member 62 through the provision of a thrust bearing 72.
More specifically, an inner race 74 is mounted around the discoid ~67Q43 element and an outer race 76 is mounted upon the cantilevered member 62. A series of peripherally spaced rollers 78 are inter-calated between the races and serve to reduce frictional contact between the inner and outer races as the discoid element 70 rotates with respect to the cantilevered member 62. The discoid element 70 may be fitted with a plurality of generally radially extending vanes 80 which serve to contact waste material falling thereupon.
The discoid element may be freely rotating or externally rotated by a~-hydraulic or electric drive. The primary function of the discoid element is to contact and direct waste màterial falling within the container toward the center thereof without encountering frictional scouring and damage in the process. The element 70 is preferably pitched on an angle of from 15 to lS 20 with a central axis pointing toward the upper opposing end of the container. It has been found that such a discoid element will serve ~ tightly compact waste material within the container toward the opposing end of the container.
To assist in the compacting function of the subject invention the interior container wall is further fitted with translating vanes 86 which may be extensions of the previously described packing vanes 60. The translating vanes are applied - to the interlor wall of the container with a left handed helical twist taken from a line of sight toward the center of the container from the rearward end wall. Accordingly, as the cylinder 40 rotates clockwise about the longitudinal axis thereof, material within the container will tend to be crushed or carried from the rearward end wall 44 toward the center of the container to tightly pack the waste material within the container and reduce interstitial voids therein.
:~)67043 In a perferred embodiment of the subject invention the packing vanes 60 each carry a plurality of radially extending longitudinally spaced projections or teeth 90. The teeth 90 serve to firmly engage refuse deposited within zone 56 and carry the refuse into the container as previously detailed.
Further a perferred embodiment of the invention may ; include a breaker assembly 92 resiliently mounted upon the end w211 44. The breaker assembly 92 is cantilevered from the end wall in a posture substantially above the discoid element, note FIGURE 3. The breaker assembly 92 includes a bracket 94 which carries a pivotally mounted breaker arm 96. The breaker arm 96 extends toward but is spaced from packing vanes 60, note FIGURE 3, and is resiliently maintained in position by spring steel str-aps98.
The outward extremity of the breaker arm 96 i5 fitted with-generally radially extending projections or teeth 100 which function in mutually opposing cooperation with pa~kin~ -vane teeth 90 to reduce the size of large waste items as the items are lifted into the container 40. More specifically oversized items are-lifted upwardly upon counterclockwise rota-tion of the cylinder 40 as viewed in FIGURE 3. As the oversized object impacts the breaker arm 96 it will contact teeth 100 which will tend to reduce or shred the object as the container rotates. In the event the oversized object is particularly tough or resistant to size reduction the resilient straps 9~ will flex and breaker arm 36 will pivot upwardly kicking the oversized object back down into the receiving zone 56. The process is repeated as the container 40 continues to rotate until the object is reduced in size so as to pass by the breaker arm 96 without engagement.
At the forward end of the container 40 the end wall 42 is provided with a discoid element 110 and breaker assembly 112 which are identical with their counterparts at the rearward ` end of the container. Accordingly these elements will not be described in detail except by reference to the previously noted counterpart elements. The mounting of the forward end elements, however, are mirror images of the rearward counterpart elements.
In this regard the cylindrical container 40 is preferably fabricated with a continuous shell from one end to the other~
Thus clockwise rotation of the cylinder when viewed from the rearward end is counterclockwise rotation of the cylinder when viewed from the forward end.
lS In the above vein helical translating vanes 114 extending from the forward en~ of the container are opposite handed when compaired wit~ ' anes 90 mounted at the rearward end of the container 40. Preferably the translating vanes 90 and 114 meet - in approximately the center of the container and function in conjunctlon with the discoid elements 70 and 110 to tightly compact waste material within the container from both ends thereof.
The method aspects of the subject invention have been expressly or implicitly set forth in the foregoing but in brief sum include the steps of depositing waste material within either receiving zone 54 at the forward end of container 40 or receiving zone:S6 at the rearward end thereof. The waste material is then lifted into the container at each end and directed and translated toward the center of the container ' through the provision of discoid elements 70 and 110 and translating vanes 90 and 114. The waste material is thus tightly packed against other waste material to minimize interstitial voids within a fully loaded container.
In the event large or oversized waste objects are deposited within receiving zones 54 and 56 they will be resiliently resisted by the breaking assemblies 92 and 112 in a manner as described more fully hereinabove.
In describing a method and apparatus for collecting and compacting waste material in accordance with a perferred embodiment of the invention those skilled in the art will recog-nize several advantages which singularly distinguish the subject invention from previously known devices.
A particular advantage is the realization of a method and apparatus for waste material collection and compaction which will provide a tighter more fully packed out container. This will reduce the number of cycles to a common dumping area, increase the efficiency of crews and decrease the cost of operating a waste collection enterprise.
Additionally the frictionless wear saving characteristics of the instant assignees prior inventions have been maintained while increasing container pay loads.
Still further the option of both front and rear end loading facilitates operator use and loading.
Additionally the resiliently mounted breaker bar aspect of the invention permits reduction of oversized items without jamming or fouling the normal loading and charging operation.
In describing the invention, reference has been made to a preferred embodiment. Those skilled in the art, however, and familiar with the disclosure of the subject invention, may recognize additions, deletions, substitutions, modifications and/or other changes which will fall within the purview of the invention as defined in the following claims.

Referring now to the drawings and particularly FIGURE 1, there will be seen an axonometric view of a motor vehicle 10 operably carrying a collection and compacting apparatus 12 ` 1n accordance with a perferred embodiment of the invention.
The motor vehicle 10 is generally of a conventional design but includes a cab 12 with a permanently open right hand door frame 16 such that an operator or an operator's ; assistant may facilely alight to pick up trash etc. along a curb. The vehicle 10 further includes a chassis 18 comprising a pair of channel beams 20 and 22, note FIGURE 3 which extended rearwardly from the cab and longitudinally beneath the apparatus for collecting and compacting waste material 12.

The foregoing motor vehicle structure, as previously nentioned, is intended to be a generally conventional design of the type which may be procurred from motor vehicle companies.
~nce the motor vehicle is purchased it may then be fitted with . 3 waste material collection and compacting apparatus 12 in accordance with the subject invention.
The subject invention entails a generally hollow -ylindrical container body 40 having an end wall 42 and 44 positioned across the forward and rear end thereof respectively.
rhe end walls are each mounted upon the motor vehicle chassis 18 and remain stationary while the container body 40 is mounted ~or rotational movemen~ upon the chassis 18 as previously describ-~d. Moreover the rearward end wall 44 is pivotally mounted as at 48 to a chassis carried yoke 50. This pivotal mounting arrangement permits the end wall 44 to be swung upwardly and ~pen to disgorge compacted trash from within the container at a central dump or land fill area.

Packing vanes 60 serve to engage waste material deposited within the receiving zone 56 and lift the waste material into the interior of the cylinder 40 upon rotation thereof.
The rearward end wall 44 carries a cantilevered member 62 which semiconically projects inwardly therefrom in a posture longitudinally displaced from but blocking the opening 52.
The member 62 is fashioned with a recess 64 within the right ~ side~thereof, as viewed in FIGURE 3, which forms in cooperation ,~ with the end wall 44 and packing vanes 60 an opening to receive waste material deposited within receiving zone 56. In this connection as the cylinder 40 is rotated in a counterclockwise directionj,as viewed in FIGURE 3, waste material will be lifted upwardly by packing vanes 60 passed recess 64 and into the con-~, tainer 4~
The left hand side of the member 62 is closed andterminates with an edge surface 68 toward the bottom of the ~, 20 container. The semiconical wall of member 62 on the left side ~, thereof prevents waste material lifted into the container from , falling back into the receiving zone 56.
`~ The waste material after being lifted into the container generally falls onto a rotatably mounted, arcuate discoid element 70. The discoid element 70 is circular and mounted upon the member 62 through the provision of a thrust bearing 72.
More specifically, an inner race 74 is mounted around the discoid ~67Q43 element and an outer race 76 is mounted upon the cantilevered member 62. A series of peripherally spaced rollers 78 are inter-calated between the races and serve to reduce frictional contact between the inner and outer races as the discoid element 70 rotates with respect to the cantilevered member 62. The discoid element 70 may be fitted with a plurality of generally radially extending vanes 80 which serve to contact waste material falling thereupon.
The discoid element may be freely rotating or externally rotated by a~-hydraulic or electric drive. The primary function of the discoid element is to contact and direct waste màterial falling within the container toward the center thereof without encountering frictional scouring and damage in the process. The element 70 is preferably pitched on an angle of from 15 to lS 20 with a central axis pointing toward the upper opposing end of the container. It has been found that such a discoid element will serve ~ tightly compact waste material within the container toward the opposing end of the container.
To assist in the compacting function of the subject invention the interior container wall is further fitted with translating vanes 86 which may be extensions of the previously described packing vanes 60. The translating vanes are applied - to the interlor wall of the container with a left handed helical twist taken from a line of sight toward the center of the container from the rearward end wall. Accordingly, as the cylinder 40 rotates clockwise about the longitudinal axis thereof, material within the container will tend to be crushed or carried from the rearward end wall 44 toward the center of the container to tightly pack the waste material within the container and reduce interstitial voids therein.
:~)67043 In a perferred embodiment of the subject invention the packing vanes 60 each carry a plurality of radially extending longitudinally spaced projections or teeth 90. The teeth 90 serve to firmly engage refuse deposited within zone 56 and carry the refuse into the container as previously detailed.
Further a perferred embodiment of the invention may ; include a breaker assembly 92 resiliently mounted upon the end w211 44. The breaker assembly 92 is cantilevered from the end wall in a posture substantially above the discoid element, note FIGURE 3. The breaker assembly 92 includes a bracket 94 which carries a pivotally mounted breaker arm 96. The breaker arm 96 extends toward but is spaced from packing vanes 60, note FIGURE 3, and is resiliently maintained in position by spring steel str-aps98.
The outward extremity of the breaker arm 96 i5 fitted with-generally radially extending projections or teeth 100 which function in mutually opposing cooperation with pa~kin~ -vane teeth 90 to reduce the size of large waste items as the items are lifted into the container 40. More specifically oversized items are-lifted upwardly upon counterclockwise rota-tion of the cylinder 40 as viewed in FIGURE 3. As the oversized object impacts the breaker arm 96 it will contact teeth 100 which will tend to reduce or shred the object as the container rotates. In the event the oversized object is particularly tough or resistant to size reduction the resilient straps 9~ will flex and breaker arm 36 will pivot upwardly kicking the oversized object back down into the receiving zone 56. The process is repeated as the container 40 continues to rotate until the object is reduced in size so as to pass by the breaker arm 96 without engagement.
At the forward end of the container 40 the end wall 42 is provided with a discoid element 110 and breaker assembly 112 which are identical with their counterparts at the rearward ` end of the container. Accordingly these elements will not be described in detail except by reference to the previously noted counterpart elements. The mounting of the forward end elements, however, are mirror images of the rearward counterpart elements.
In this regard the cylindrical container 40 is preferably fabricated with a continuous shell from one end to the other~
Thus clockwise rotation of the cylinder when viewed from the rearward end is counterclockwise rotation of the cylinder when viewed from the forward end.
lS In the above vein helical translating vanes 114 extending from the forward en~ of the container are opposite handed when compaired wit~ ' anes 90 mounted at the rearward end of the container 40. Preferably the translating vanes 90 and 114 meet - in approximately the center of the container and function in conjunctlon with the discoid elements 70 and 110 to tightly compact waste material within the container from both ends thereof.
The method aspects of the subject invention have been expressly or implicitly set forth in the foregoing but in brief sum include the steps of depositing waste material within either receiving zone 54 at the forward end of container 40 or receiving zone:S6 at the rearward end thereof. The waste material is then lifted into the container at each end and directed and translated toward the center of the container ' through the provision of discoid elements 70 and 110 and translating vanes 90 and 114. The waste material is thus tightly packed against other waste material to minimize interstitial voids within a fully loaded container.
In the event large or oversized waste objects are deposited within receiving zones 54 and 56 they will be resiliently resisted by the breaking assemblies 92 and 112 in a manner as described more fully hereinabove.
In describing a method and apparatus for collecting and compacting waste material in accordance with a perferred embodiment of the invention those skilled in the art will recog-nize several advantages which singularly distinguish the subject invention from previously known devices.
A particular advantage is the realization of a method and apparatus for waste material collection and compaction which will provide a tighter more fully packed out container. This will reduce the number of cycles to a common dumping area, increase the efficiency of crews and decrease the cost of operating a waste collection enterprise.
Additionally the frictionless wear saving characteristics of the instant assignees prior inventions have been maintained while increasing container pay loads.
Still further the option of both front and rear end loading facilitates operator use and loading.
Additionally the resiliently mounted breaker bar aspect of the invention permits reduction of oversized items without jamming or fouling the normal loading and charging operation.
In describing the invention, reference has been made to a preferred embodiment. Those skilled in the art, however, and familiar with the disclosure of the subject invention, may recognize additions, deletions, substitutions, modifications and/or other changes which will fall within the purview of the invention as defined in the following claims.
