  • the pedal 104 In order to release the movable container section 2 from the power section 1, the pedal 104 is depressed, thereby pivoting the lever 105 in the direction of the arrow D (FIG. 7). This causes the arm 107 to move in the direction of the arrow B (FIG. 7), thereby causing the bent over end 111 to move in the direction of the arrow B to force the bolt 100 against its spring bias away from the horizontally extending member 13. Similarly, the arm 113 on the other side of the movable container section 2 operates to release the bolt 101 from horizontally extending member 13. Then, the movable container section 2 can be withdrawn from the power section 1 by the operator.

  • the movable container section 2 incorporates a liner similar to that disclosed and claimed in US. Pat. No.
  • FIG. 4 the liner construction of the present invention is illustrated in greater detail.
  • liner 140 is of generally rectangular shape and is made of a substantially rigid, but flexible material, such as polyethylene.
  • the liner 140 is preferably fabricated as an integral structure, but it may be fabricated of several pieces jointed together.
  • the upper portion 142 of the liner 140 extends above the upper level of the compacting chamber 14. In this connection, see FIG. 1 wherein the liner 140 is shown inserted into the compacting chamber 14.
  • the upper portion 142 of the liner has slots 144 formed therein. The slots are located so that when the ram 40 is lowered to its lowermost compacting position, the portions 145 of the ram which connect the ram head to the drive structure pass through the slots 144 in the upper portion of the liner.
  • the upper portion 142 of the liner is provided so that the con- V smaller portion of the compacting chamber will be effectively utilized. If the compacting chamber 14 were extended to reach the upper level of the liner 142, then the amount of metal and other high strength components would be increased. In addition, the overall height of the compactor would be increased, thereby increasing the cost of the system and increasing the weight and difficulty of handling of the movable container. Since the slots 144 are relatively narrow, it has been found that there is no danger of refuse or other material to be compacted from falling out of the liner through the slots. As mentioned above, the slots in the upper portion of the liner are provided so that the ram may pass therethrough and compact the material within the chamber 14 so as to provide more efficient utilization of component materials. Slots 144 in the liner 140 afford the main advantage of greater effective compaction chamber capacity while minimizing overall height of entire compactor. This is a very important feature of the invention.
  • a plastic or other disposable bag 146 is located between the outer chamber 14 and the liner 140. See FIG. 1.
  • the liner 140 is bottomless. After compaction, the door is opened by depression of the pedal 23, thereby opening the door 16 to the compaction chamber 14. This effectively releases some pressures built up on the liner and enables the liner 140 to be easily lifted out of the compacting chamber 14. Thus, the compacted material will remain in the plastic or other disposable bag 146, which can then be tied and easily removed from the apparatus.
  • a further safety feature of the present invention is the provision of an additional locking member 147 on the housing of the power section 2 which prevents the door 20 from being opened when the container section 2 is locked into the power section 1.
  • the lock 147 is illustrated best in FIG. 1. When the container section 2 is engaged into the power section 1, the lock member 147 is located above the upper surface 20a as shown in dashed lines in FIG. 1. This prevents the door 20 from being raised by depression of the pedal 23 when the power and movable sections of the compacting apparatus are engaged.
  • a further feature of the compacting apparatus is the provision in the rear portion of the power section 1 of a compartment for storing a roll of plastic or other type of disposable bag for use with the compacting device.

  • the compactor ram 40 is in its upper position with both the top limit switch 166 and the reversing switch 167 in the open position as shown in FIG. 10.
  • power is turned on by means of turning on the lock switch 7 and operating the on-off switch 9.
  • the unit With power on, the unit is activated by pressing the momentary start switch 8. This provides power to the main power relay 171 and causes the motor 49 to operate to move the ram downward.
  • the top limit switch 166 closes, thereby allowing the operator to release the momentary start switch.
  • the reversing switch closes activating the reversing relay 175.
  • no reversal of the ram movement occurs since the motor centrifugal switch is open during rotation of the motor shaft.
  • the ram 40 continues its downward movement and operates to compact material in the container.
  • An advantage of the ram stop 80 in connection with the circuitry and construction of the present invention is that as the ram 40 contacts the ram stop 80, the motor slowly begins to slow down. As the motor slows down, the centrifugal switch 174 therein operates to cause the direction of rotation of the motor to be reversed. Thus, the motor is thrown into reverse when it is operating at a relatively low rpm. This reduces the strain and electrical requirements placed on the motor. If a conventional type of sensing arrangement were used for sensing the bottom of travel of the ram, the motor would be thrown into reverse when it is operating at a relatively high speed, thereby imparting unnecessary wear and tear on the motor arrangement. With the present invention, a smooth transitional and reversing operation is achieved while imparting minimum wear on the motor and drive chain.
  • the hidden lock switch 165 is used only for maintenance operations when the ram must be partially or fully lowered with the carriage or container section 2 removed from the power section 1.
  • control circuits may be used in connection with the compacting apparatus of the present invention.
  • the above-described control circuit illustrated in FIG. has been found to be advantageous and has been described by way of example.
  • An important constructional feature of the apparatus of the present invention is the cantilever-type construction of the portable container unit. This type of construction allows the unit to be fully inserted into the power unit so as to enable the overall apparatus to the more compact. The forces of compaction are borne by the base plate 35 of the power unit.
  • slots 144 in the liner 140 facilitate setting up of the container unit with a disposable bag.
  • a disposable bag 146 such as a plastic bag.
  • the bag 146 is somewhat limp and could be difficult to handle.
  • the liner 140 is mounted on the upper edge of the container 14 with the upper edge of the container engaging slots 144 on opposing walls of the liner.
  • the slots of the liner saddle the chamber wall with the liner in an inverted position.
  • the bag 146 is easily applied over the liner 140.
