The compactor of this invention includes a housing having two longitudinally spaced ends, one of which is open and spanned by a door. A discharge blade and a packer blade are located within the housing between the housing ends. The discharge blade is shiftable between a load position and a discharge position within the housing. The packer blade is shiftable independently of the discharge blade between a load position located rearwardly of the discharge blade and a pack position located at or forwardly of the discharge blade which causes the material as it is placed in the compactor to be pushed into an area within the housing in front of the discharge blade where the material is compact'ed. When it is desired to unload the compactor, the packer blade is shifted into alignment with the discharge blade and the two blades shifted as a unit into 1 the discharge position for the discharge blade, causing the compacted material within the housing to be pushed through the open end of the housing.
Heretofore it has been a common practice to construct refuse compactors with a single blade which is utilized both for the packing operation and the unload-' ing or discharge operation. The compactor of this invention in utilizing one blade for discharge purposes and a separate blade for packing purposes allows for greater compaction within a unit volume than the single blade prior art compactor unit's.
Another advantage of the compactor of this invention over prior art compactors is that material products can be introduced into the unit anytime during the packing operation or cycle.
Still another advantage of the compactor unit of this invention over the prior art single blade refuse compactors is that the use of an individual packer blade allows agreater' packing pressure to be applied to the product material for agiv'en power in ut than can be applied to the material when a single large blade is used for both packing and discharging.
Another advantage of the compactor of this invention is that the loading space of the compactor remains constant during the packing cycle, while in the single blade refuse compactors the loading space decreasesas the amount of compacted material within the compac-- to'r increases.
Accordingly, it is an object of this invention to provide a compactor for compressible material which is of efficient operation.
lt is another object of this invention to provide a refuse material compactor in which a rhaximurn amount of refuse can be compacted for a given volume of ref'use storage space within the compactor.
Still another object of this invention is to provide a refuse cornpactdr in which the refuse loading area remains of substantially constant volume and which can be loaded during the compacting cycle.
Other objects of this invention will become apparent upon a reading of the invention s description.

DESCRIPTION OF THE PREFERRED EMBODIMENT The preferred embodiment illustrated is not intended to be exhaustive or to limit the'invention to the precise form disclosed. It is chosen and described in order to best explain the principles of the invention and its application and practical use to thereby enable others skilled in the art to best utilize the invention.
In the embodiment of the compactor of this invention shown in FIGS. 2-9, the reference numeral 10 refers to a housing which is shown fixedly seated uponthe bed of a truck 12. Truck 12 lends mobility to the compactor which, if desired, could be mounted to a suitable fixed foundation or immobile support. Housing 10 of the compactor includes a bottom wall 14, top wall 16, side walls 18, and a front end wall 20. The rear end of housing 10 is spanned by a door 22. Door 22 is hinged to .top wall 16 of housing 10 and is shiftable between the closed position shown inFIGS. 2 and 8 and the open position shown in FIG. 9 by means of hydraulic cylinder power units 24. A pin and slot lock 21 or other suitable locking means is utilized to secure door 22 in its closed position during the compacting cycle of the unit. Door 22 has an inner concave configuration whose purpose is well understood in the compactor art. A partition wall 26 is located within housing 10 and extends between side walls 18 and downwardly from top wall 16, terminating in a lower edge 28 which is spaced above bottom wall 14 of the housing.
DISCHARGE BLADE ASSEMBLY A discharge blade assembly 30 is located within housing 10 and is supported upon housing bottom wall 14 for longitudinal shiftable movement within the housingpDischarge blade assembly 30 includes a blade part 32 having a concave blade front 34. Blade front 34 extends substantially from one side wall 18 to the other side wall 18 of the housing and from top wall 16 downwardly, terminating in a lower edge 36 which is at the same approximate level as lower edge 28 of partition wall 26. Discharge blade assembly 30 includes spaced side frame members 38 which support blade part 32 and which are connected by transverse frame members 40-41. Transverse frame members 40-41 preferably rest upon bottom wall 14 of housing 10 with frame members 38 being positioned adjacent side walls 18 of the housing.
A pair of hydraulically actuated cylinder power units 42 are positioned on opposite sides of housing 10 and are connected between front end wall 20 of the housing and discharge blade assembly 30, preferably adjacent its blade part 32. Each hydraulic cylinder power unit 42 includes a cylinder part 44 and a piston part 46. Actuation of power units 42 causes the extension and retraction of piston parts 46 thereof and the resulting longitudinal shiftable movement of discharge blade assembly 30 over bottom wall 14 from its load position, illustrated in FIGS. 2, 5, 7 and 8, and its discharge position, illustrated in FIG. 9. To guide the shiftable movement of discharge blade assembly between its load and discharge positions, a pair of guide rails 48 are secured to side walls 18 of the housing. Guide rails 48 fit slidably within longitudinally extending channel members 50 which form a part of side frame members 38 of'blade assembly 30.
PACKER BLADE ASSEMBLY A packer blade assembly 52 is located within housing 10 for longitudinal shiftable movement beneath the lower edge 28 of partition wall 26 and lower edge 36 of discharge assembly blade front 34. Packer blade assembly 52 includes a box frame part 54 having side frame members 56 and a connecting top panel 58. Box frame part 54 of blade assembly 52 includes a transverse frame member 60 which extends between side frame members 56. A blade part 62 having a blade front 64 extends across box frame part 4 and is joined to the top panel 58 and side frame members 56 of the frame part. A vertical support 59 extends between panel 58 and frame member 60. Packer blade assembly 52 fits between side frame members 38 of discharge blade assembly 30 and is'shiftable longitudinally within housing relative to blade assembly 30. Discharge blade assembly 30 is provided with guide rails 66 which extend along side frame members 38 and over transverse frame members 40 and 41 of the blade assembly. Side frame members 56, transverse frame member 60 and blade part'62 of packer blade assembly '52 have channels 68 formed therein. Guide rails 66 of discharge blade assembly 30 fit slidably within channels 68 of packer blade assembly 52 and serve to guide longitudinal movement of the packer blade assembly from the load position illustrated in FIGS. 2, 5 and 7 to the pack position shown in FIG. 8 with the discharge blade assembly being held stationary by power units 42.
Top panel 58 of packer blade assembly 52 is con structed so as to pass just under lower edge 28 of partition wall 26 and lower edge 36 of discharge assembly blade front 34 during movement of the packer blade assembly between its load and pack positions. A pair of hydraulically actuated cylinder power units 70 are connected between discharge blade assembly 30 and packer blade assembly 52 for the purpose of shifting the packer blade assembly between its load and pack positionsv Power units are carried by blade assembly 30 and preferably extend between a transverse frame member 72 forming a part of blade assembly 30 and blade part 62 of packer blade assembly 52. Each power unit 70 includes a cylinder part 74 and a piston part 76 which upon extension and retraction cause packer blade assembly 52 to be shifted relative to the discharge blade assembly between its load and pack positions.
Housing 10 of the compactor has a material loading opening 78 formed in at least one and preferably each of its side walls 18. Each loading opening 78 is located between partition wall 26 and blade part 32 of the discharge blade assembly when the blade assembly 30 is located in its load position illustrated in FIGS. 2, 5 and 7. Transverse frame member 41 of discharge blade assembly 30 extends under the lower edge 28 of partition wall 26 when the discharge blade assembly is in its load position and under lower edge 36 of discharge assembly blade front 34. As best shown in FIGS. 5 and 7, blade front 64 of packer blade assembly 52 is located so as to be in substantially continuous blade-defining alignment with partition wall 26 at its lower edge 28 when the packer blade assembly is in its load position. As best shown in FIG. 8, blade front 64 of packer blade assembly 52 is located in substantial bladedefining alignment with blade front 34 of discharge blade assembly 30 at its lower edge 36 when the packer blade assembly is shifted into its pack position. It is to be further noted that top panel 58 of packer blade assembly 52 extends from lower edge 28 of partition wall 26 to lower edge 36 of discharge blade assembly blade front 34 when the packer blade assembly is in its pack position. If desired, sliding or hinged doors (not shown) may be provided to cover openings 78 in housing 10.
A suitable hydraulic pump and power unit, designated generally by the reference numeral 80, is located within housing 10, preferably between partition wall 26 and front end wall 20 of the housing. Hydraulic pump and power unit 80 is connected by suitable conduits (not shown) to power units 42, 70, and, if desired, to door power units 24. Suitable actuator controls which are accessible from either the cab of truck 12 or exteriorly of housing 10 are provided and connected into power unit 80 for the purpose of actuating the power units 42, 70 and 24.
SEQUENCE OF OPERATION OF COMPACTOR UNIT With discharge blade assembly 30 located in its load position and packer blade assembly 52 located in its load position, as shown in FIGS. 2, 5 and 7, refuse or similar compressible material products are loaded into housing 10 through openings 78 and deposited upon transverse frame member 41 of discharge blade assembly 30, in front of blade part 62 of the packer blade assembly. Cylinder power units 70 are then actuated to cause packer blade assembly 52 to move toward the open end of housing 10 in the direction of arrow 82 in FIG. 2 into its pack position illustrated in FIG. 8. As blade assembly 52 is shifted into its pack position, the refuse resting upon transverse frame member 41 of discharge blade assembly 30 in front of blade part 62 is pushed under lower edge 36 of discharge assembly blade part 32 and into that area 53 of housing 10 between blade part 32 and door 22. During movement of the packer blade assembly 52 between its load and its pack positions, discharge blade assembly 30 remains stationary.
Additional refuse can be loaded through opening 78 and deposited within housing as packer blade assembly 52 is being shifted between its load and pack positions. Refuse depositedthrough housing opening 78 while the packer blade assembly is located in its pack position will fall upon top panel 58 of the blade assembly and be retained by partition wall 26 which prevents the added refuse from passing into the front portion of housing 10 where hydraulic power unit 80 is located. As power units 70 cause packer blade assembly 52 to shiftably return to its load position, the top panel 58 of the blade assembly moves relative to the added refuse until the material is able to fall onto transverse frame member 41 of the discharge blade assembly 30, at which time the packer blade assembly 52 can again be shifted into its pack position to cause this added refuse to be pushed. into the storage area 53 of housing 10 to the front of blade front 34 of the discharge blade assembly part 32.
As the refuse accumulates in storage area 53 between discharge assembly blade part 32 and closed door 22, it moves in the general circular direction of arrows 84 seen in FIG. 2, first contacting the inner concave surface of locked door 22 and later the concave surface of blade front 34 of discharge assembly blade part 32 as compaction of the refuse takes place. At no timeduring the compacting operation is it necessary to shift discharge blade assembly from its load position. The relatively small compact area of blade front 64 of packer assembly blade part 52 causes a high compressive force to be exerted upon the refuse as it is urged by the packer blade part into the refuse storage area 53, thus resulting in a high degree of compaction of the refuse within the storage area. If desired, the controls for power units 70 of packer blade assembly 52 can be cycled so that the packer blade assembly is placed in continuous reciprocating motion during loading of the compactor. Also if desired, blade front 64 of packer assembly blade part 62 need not stop at lower edge '36 of blade front 34 of the discharge blade assembly during its compaction cycle. The packer blade assembly can be designed so that when in its pack position its blade from 64 protrudes well beyond the lower edge 36 of discharge blade assembly 30 and into the storage area 53 of housing 10.
Once the storage area 53 between door 22 and discharge blade assembly 30 has been filled with compacted refuse, the shiftable movement of packer blade assembly 52 is stopped with its blade front 64in substantial blade-defining alignment with blade front 34 of discharge blade assembly 30 which has remained in its loading position. Power units 42 are now actuated to move discharge blade assembly 30 from its load position shown in FIG. 8 into its discharge position shown in FIG. 9, with door 22 being opened, causing the compacted refuse within storage area 53 to be pushed out the open rear end of housing 10. During movement of discharge blade assembly 30 from its load into its discharge position, packer blade assembly 52 which is carried upon blade assembly 30 moves with the discharge blade assembly with its blade front 64 being held immovable relative to the discharge blade assembly and remaining in substantial alignment with blade front 34.
Once the refuse is pushed from housing 10, discharge blade assembly 30 and packer blade assembly 52 are moved by power units 42 and into their respective load positions to begin the compaction cycle again.
During the operational sequence of the compactor, the operator may find that the loading area 55 between partition wall 26 and blade part 32 of discharge blade assembly 30 still contains refuse material at the time the storage area 53 between discharge blade assembly 30 and door 22 becomes filled. When this occurs, truck 12 is driven to the discharge site and door 22 is opened. The packer blade assembly 52 is thenjactuated so as to cause-all the refuse within loading area 55 to be urged into the storage area 53 with the'excess compacted refuse within the storage area falling from the open end of housing 10. After the loading area 55 of housing 10 is empty, the blade front 64 of packer blade assembly 52 is brought into alignment with blade front 34 of discharge blade assembly 30 and the discharge blade assembly moved from its load into its discharge position causing theremaining refuse within the storage area 53 to be pushed out of the open rear end of the housing. 7 v
The prior art compactor shown in FIG. 1 includes a one-piece packer blade which is shiftable longitudinally within housing 10 of the compactor. Actuation of packer blade 90 of the prior art compactor causes the refuse materal to flow in the general direction of arrows 92 of FIG. land to assume the general position bounded by broken line 94, housing bottom wall 96 the compactor remains the same during the compaction cycle.
It is-to be understood that the invention is not to be limited to the details herein given, but may be modified within the scope of the appended claims.
