  • Piston rod 68 extends rearwardly and is similarly coupled at 74 to a transverse frame member 76 of the housing, which may be an l-beam extending between and fixed to the side walls of the housing.
  • cylinder 64 is elongated so as to extend rearwardly beneath the frame member 76 as shown in FIG. 5. This provides a substantial addition to the ram stroke without increasing the overall length of the compaction apparatus, thereby permitting'grcater extension of the blade than has heretofore been possible in such a compact configuration.
  • the hydraulic system also includes a pump 78 driven by an electric motor 80, the pump drawing hydraulic fluid from a sump or reservoir 82 and forcing it through a check valve 84 to a two-way reversing valve 86, which is biased to a rest position by a spring (not shown) and moved to its opposite position by a solenoid 88.
  • the hydraulic fluid lines 90 and 92 interconnect the cylinders 62 and 64 so that the piston rods 66 and 68 tend to be driven in opposite directions. Since rod 68 is fixed, cylinders 62 and 64 are moved as a unit in the same direction as the movement of rod 66. Operation of the hydraulic system will be described later in conjunction with the electrical control circuit shown in FIG. 7.

  • transitional portion 100 is of ontinually reduced to match the forward and rearward portions of the snout (see FIG. 2).
  • the transitional portion may taper in both a vertical plane and a horizontal plane, in the preferred form of the invention illustrated the taper is principally in the horizontal plane, since the height of the snout is approximately the same from one end to the other.
  • the sides of the transitional section may comprise alternating curved sections 102 and pyramidal sections 104, the curved sections having nodes 106 at the'junction with the rear portion 96 of the snout.
  • Such transitional sections per so are well known in the sheet-metal art, for example. In general it is desired that the transition take place as smoothly as practical.
  • the snout may be attached to the housing by means of four fasteners 108, one each at the top and bottom walls and the side extremities of the rear portion 96 of the snout.
  • the fasteners may include bolts welded to the housing and extending into sleeves welded to the snout and fixed thereto by nuts.

  • a stiffening member, such as the l-beam 116, may be welded to the front wall of the housing and have its ends welded to side extensions 118 (FIG. 5) ofthe housing for stiffening the front wall structure.
  • an arm 120 extends forwardly cantilever-fashion from the rear portion 96 of the snout and supports a switch LS3 adjacent to its forward end.
  • the arm is spaced from the upper surface of the forward portion of the snout sufficiently to permit a receptacle D, such as a drum, to be placed over the snout, as will be described hereinafter, and to engage the depending actuating arm of the switch.
  • the compaction apparatus is actuated automatically in response to the presence of material, such as trash, at the inlet opening 1 (HO. 5) at the top side of the receiver chamber 12.
  • the apparatus of the invention may be located in the basement of multistory apartment building beneath the lower end of a chute 122 shown in phantom lines in FIG. 1, the housing being extended upwardly as indicated by the phantom lines to provide an enclosure or hopper into which the material to be compacted may fall.
  • Wall 34 is extended as indicated by line 34" to constitute a deflection plate for the material which falls through the chute from the upper levels of the apartment house under the influence of gravity.
  • the blade normally rests in its extended or forward position and blocks the inlet opening i at the top of the receiver chamber. Material dropping from the chute thus comes to rest upon the top side of the blade where it may interrupt a light beam projected from a light source 124, located above the blade at one side of the housing, to a photoelectric relay 126, similarly located at the opposite side of the housing, small holes being provided in the housing sidewalls for passage of a light beam.
  • a light source 124 located above the blade at one side of the housing
  • a photoelectric relay 126 similarly located at the opposite side of the housing, small holes being provided in the housing sidewalls for passage of a light beam.
  • the pump motor may be supplied from 208 volt three-phase supply lines 130 through a motor starter relay 132. 1 l5 volt etc. for the remainder of the circuit is provided by a transformer 134 connected across two of the three-phase lines, ground for one side of the volt system and for the motor M being connected to one side ofthe secondary winding oftransformer 134.
  • the light source l24 and photoelectric relay 126 are supplied from transformer 134 as shown, an indicator lamp 136 being provided to show that the system is energized.
  • the motor starter relay 132 is controlled by relay CR1, which closes a circuit for energizing the motor starter relay when the light beam from source 124 is interrupted so as to close the contacts of relay 126, thereby completing a circuit through the coil of relay CR1 and the on-off switch 138.
  • Actuation of relay 126 also completes a circuit for relay CR3, which closes two sets of contacts, the upper contacts illustrated extending an energization circuit to relay CR2 and the lower contacts illustrated providing a holding circuit for relays CR1 and CR3 through the upper contact of a limit switch LS1 having a switch blade which is held closed upon its upper contact by the compaction blade and is permitted to move to its lower contact when the blade is in its forward or rest position.
  • relay CR2 Energization of relay CR2 closes its two sets of contacts, the upper set completing an actuating circuit for solenoid 88 of the twoway control valve, and the lower contacts completing a hold ing circuit for relay CR2 through limit switch LS2, which is normally closed and which is opened by the compaction blade when the blade reaches its fully retracted position.
  • Limit switches LS1 and LS2 may be positioned on a side wall of the housing as indicated in phantom lines in FIG. 1 and may have actuating arms which project through openings in the side wall to engage the blade cam C.
  • a manual reverse switch R shunts the upper contacts of upper relay CR2 and thus permits energization of solenoid 88 independently of the relay.
  • a pressure switch PS shunts the lower contacts of limit switch LS1 for a purpose to be described hereinafter.
  • Switch LS3 previously described in connection with the snout, controls relay CR4 for energizing an indicator lamp 140 to indicate that the container or receptacle is full, and to interrupt operation of the compaction apparatus, as will also be described hereinafter.
  • Photoelectric relay 126 is actuated, closing motor starter relay 132 and energizing pump motor 80.
  • an actuating cam C (indicated in phantom lines in FIG. 6) fixed to the rear of the blade engages the actuating lever of switch LS1 and closes it upon its lower contact.
  • Actuation of photoelectric relay 126 not only energizes relay CR1 to energize the motor starter relay 132 but also energizes relay CR3, which closes its contacts and energizes relay CR2 through limit switch LS1.
  • Relay CR2 closes its contacts, energizing solenoid 88 and providing a self-holding circuit through limit switch LS2 and the closed upper contacts of relay CR3.
  • Energization of sole noid 88 places the control valve 86 in a position which causes the compaction blade 42 to move rearwardly, releasing the blade of switch LS1 and permitting it to close normally upon its upper contact'and providing a holding circuit for relays CR1 and CR3 through the closed lower contacts of the latter.
  • the material on top of the blade falls into the receiver chamber 12, removing the interruption of the light beam and permitting photoelectric relay 126 to open its contacts.
  • Relays CR1 and CR3 remain closed, however, by virtue of the holding circuit just mentioned.
  • the pressure switch will close, energizing relay CR2 and solenoid 88, so as to reverse the movement of the blade.
  • Such movement of the blade will reduce the hydraulic pressure below the level required to hold switch PS closed and will permit the pressure switch to open, whereupon the blade will again move forward and engage the obstruction.
  • the blade will thus move back and forth, causing the teeth 58 to engage the obstruction repetitively and, by cooperation with the shear bar 110, 114, 116, to break the obstruction if possible and force the pieces into the snout.
  • the material forced into the rear portion 96 of the snout will be greatly reduced in volume when it encounters the transition section l00 and will be squeezed into the forward section 98.
  • the snout will fill up, and compacted material will extrude through outlet opening 0 into the receptacle D.
  • the receptacle which is closed at its left end (bottom) in H6. 1 and is free to move on the snout, will move forwardly along the snout under the compressive force of the compaction blade until the actuating lever of limit switch LS3 is released.
  • the receptacle is preferably placed upon the snout until its major portion (at least 50 percent) overlaps the snout.
  • the receptacle need not fit the snout snugly. because it need not partake significantly in the compaction of the material received therein.
  • An oil drum manually placed upon the snout until its bottom is a few inches from outlet 0 will move forwardly when filled until it tips and the bottom-side corner engages the floor, whereupon the drum may be manually removed from the snout and replaced by another.
  • Apparatus heretofore proposed to compact material supplied from a chute and to feed the compacted material to a receptacle employs a blade which moves the material from a receiver chamber and through a tapered snout.
  • a blade which moves the material from a receiver chamber and through a tapered snout.
  • such apparatus relies upon circular cross-sectional geometry exclusively.
  • the receiver chamber is a cylinder of circular cross section with a circular outlet opening, the diameter of the receiver chamber must be sufficient to accommodate the large diameter chutes which must be employed in apartment buildings, for example, for adequate handling of conventionally disposed items such as large cardboard boxes and bundles of newspaper.
  • the chute may have a 24 inch or a 30 inch diameter or width.
  • the diameter of the receiver chamber is commensurately large, as is necessary to prevent clogging at the inlet opening of the receiver chamber, the diameter of the outlet of the snout must also be quite large. Otherwise, the back pressure upon the packing blade becomes enormous and the amount of energy required to compact the material becomes impractically large. if a large enough snout outlet diameter is employed to prevent these conditions, the cross-sectional area of conventional receptacles is too small to fit the snout. Hence, unconventional and expensive receptacles must be employed, and such receptacles are so large that they become unwieldy, making it very difficult to handle them manually when filled.
  • the present invention overcomes the foregoing problems by providing apparatus with a receiver chamber wide enough to accommodate a large diameter chute, such as a 24 inch diameter or 30 inch diameter chute, and which yet permits the use of a relatively small diameter snout outlet commensurate with conventionalreceptacles, such as 55 gallon oil drums and paper bags of similarsize.
  • the polygonal cross section of the receiver chamber has its widest dimension disposed horizontally, (see FIG. 4) so as to accommodate the width of the chute. If a receiver chamber of circular cross section with diameter equal to the width of the receiver chamber of the invention were employed, the diameter of the outlet of the snout would have to be much too large to meet the practical considerations set forth above.
  • the cross-sectional area of the outlet of the receiver chamber of the invention is, however, substantially less than the cross sectional area of a circle with diameter corresponding to the width of the receiver chamber, and thus the cross-sectional area of the snout outlet may be made small enough to fit conventional receptacles without exceeding practical criteria for efficient compaction in terms of the amount of volume reduction obtained for a given energy input.
  • the polygonal configuration of the outlet opening of the receiver chamber may be constructed by arranging the upwardly diverging lower edges and the downwardly diverging upper edges of the opening to form right-angular corners where the upper and lower edges meet at the side extremities 22 and 24. If the lower edges defined by walls 18 and 20 were extended downwardly so as to intersect and if the corresponding upper edges of opening 0 were extended upwardly so as to intersect, the geometric FIG. thus constructed would be a square, or more accurately a diamond.
  • Such a configuration of the outlet 0 would require substantial tapering of the snout transition in a vertical plane as well as in a horizontal plane, and although this is possible, excellent performance appears to be obtained with all types of trash when the diamond configuration is truncated by cutting off the top and bottom corners. in the illustrated form of the invention this is accomplished by making the top and bottom edges of the outlet opening 0 horizontal and approximately flush with the upper and lower extremities of the circular opening 0 of the snout, the horizontal diameter ofwhich is alined with the side extremities 22 and 24 ofthe housing.
  • outlet opening 0' of the snout is thus inscribed within the confines of the polygonal outlet opening 0 of the receiver chamber, with the forwardly projected edges of this outlet opening approximately tangent to the circular outlet opening ofthe snout as indicated in FIG. 3.
  • the apparatus of the invention advantageously provides greatly reduced volume of compacted material, ofthe order of 7 to l or better, in conventional receptacles, which can be handled manually, and yet requires very little space for its installation and operation.
  • the length of the housing may be about 74 inches, the length of the snout 46 inches, the height of the housing 45 inches (plus extensions to the chute) and the width of the housing 30 /2 inches.
  • the length ofthe rearward section ofthe snout may be about 10 inches, the length of the transition section about 10 inches, and the length of the forward section 26 inches.
