Definitions

  • the invention relates to a garbage compactor unit suitable for domestic and commercial use.
  • Prior Art Known garbage compactors include a hollow container adapted to receive an inner plastic bag. A charge of garbage to be compacted having been placed within the bag, a piston like pressure plate is urged downwards against the charge with force sufficient to compact the garbage to, say, one-quarter to one-sixth its original bulk. A double extension ram moves the pressure plate downwards with force of about 3,000 pounds, which is adequate for the required compaction.
  • Such units are housed in a cabinet with a front opening door so that, the pressure plate having been retracted clear of the container, the container can be withdrawn for charging, suitable support being provided, and 'for removing the bag of compacted garbage. Since a charge placed in the bag is compacted to a fraction of its original bulk, several charges are required to fill it.
  • the container and bag are commonly rectangular in section.
  • garbage compactors With growing interest in environmental pollution, garbage compactors are coming into general use, since garbage so compacted can be handled and disposed of more readily than bulk garbage, and with less aesthetic and other pollution.
  • a difficulty with prior art constructions known to the present inventor is that the plastic bag is prone to damage from for instance, broken glass from glassware being compacted.
  • a tapered sleeve open at each end has the bag drawn over it, then the sleeve and a bag of circular section are placed within the container. Compaction is carried out generally as above, with the pressure plate, travelling downwards within the sleeve, effecting compaction. It is seen that, in this way, damage to side walls of the bag is avoided since the sleeve, which for optimum results is stainless steel, avoids damage from causes such as the above.
  • the sleeve is tapered upwards, thus facilitating withdrawal from the compacted garbage and leaving the plastic bag without side wall damage containing the compacted garbage. Both in the prior art units and in the present unit, damage to the bottom of the bag can ordinarily be prevented by applying several layers of folded newspaper to the bottom before the first charge.
  • FIG. 1 is a perspective of a garbage Compactor unit according to the present invention
  • FIG. 2 is a central vertical section on a plane parallel to a front wall of the unit, some parts not being shown in section,
  • FIG. 2A is a central vertical section on a plane parallel to a side wall of the unit, some parts not being shown in section,
  • FIG. 3 is a central vertical section of a tapered sleeve
  • FIG. 4 is a front elevation of the sleeve
  • FIG. 5 is a plan view of the sleeve, particularly showing a flange.
  • FIGS. 1 and 2A As seen in perspective in FIG. ll, a garbage compactor unit according to the present invention is designated generally 10, having a top 1 1 a side wall 12, and an opposite side wall FIG. 2A not seen.
  • a front wall 13 has an opening 13.1 closed by a door 14 extending somewhat over halfway up the front wall and being vertically hinged at 15 on side bracket structure, generally 15.1, which is clear of the opening.
  • the unit illustrated in FIG. 1 is generally rectangular in section being about 2 by 2 feet, and is some 40 inches high.
  • FIG. 2 is a central section on a vertical plane parallel to the front wall, some parts not being shown in section
  • FIG. 2A is a central vertical section on a plane parallel to the side walls, some parts not being shown in section.
  • the interior is divided in to an upper compartment 21 and a lower compartment 22 by a transverse portion 23 extending from the side wall 12 to an opposite side wall 24, the lower compartment being about twice as deep as the upper compartment.
  • the upper compartment contains a double centrally loocated extension screw ram means 25 with a circular pressure plate 26 secured to a lower end 27 of a double extension shaft 28. Travel of the ram is about twice the retracted height.
  • the ram is actuated by a pulley 29 driven by electric motor means not shown. Rotation of the pulley causes the pressure plate to move downwards from the full outline position shown to a broken outline extended positon 26.1, the full line portion being referred to as a retracted position.
  • a base assembly generally 30 at the bottom of the lower compartment 22 has a dished circular base element 31 mounted in a frame having a front member 31.1 and side members 31.2, the latter being supported on spaced roll pairs 32, 32.1, as shown secured to side walls.
  • the base element also has roll 34 in contact with the floor so that, with the door open, the base assembly 35 extends just below and inside of a flange 36 of the base element 31.
  • FIGS. 3, 4 and 5 are, respectively, a right section, a plan, and a side elevation of the tapered sleeve 35.
  • the hollow sleeve 35 tapers upwards, an upper end being secured in a circular flange .37 having a handle 38.
  • an outer hollow cylindrical member 39 has an upper flanged end 41 a lower end being supported on the base assembly.
  • the upper end 41 accepts the circular flange 37 so that the hollow tapered sleeve 35 is suspended therewithin as seen in FIG. 2 with its lower end just inside of the flange 36 of the dished element 31.
  • the unit being empty and the door closed, open the door, pull out the base assembly, and remove the tapered tubular sleeve by lifting the flange 37.
  • Plastic bags of suitable size and configuration are supplied with the unit, and are commonly available from ordinary trade sources. Pull a bag over the tapered sleeve 35 so that the bottom of the sleeve rests on the bottom of the bag with the top of the bag pulled upwards somewhat beyond the flange. The sleeve with the bag surrounding it as above, is now replaced, the upper end of the bag being secured between flange and the upper end 41 of the cylindrical member 39.
  • FIG. 2 is opened stopping themotor.
  • the sleeve 35 tapers upwards, and, the flange 37 and, with it, the sleeve 35 can be removed, removal being facilitated by the taper.
  • the tapered sleeve is stainless steel since this has a smooth finish, is strong, and it is found that a stainless steel sleeve has virtually indefinite life not ordinarily being damaged by materials being compacted.
  • the sleeve can be galvanized iron, or plastic.
  • a double extension screw ram has been exemplified, with drive from an electric motor.
  • a self reversing motor of a type used in garbage disposal units i.e., automatically reversible at a predetermined applied load, is utilized for the drive.
  • the motor reverses so retracting the pressure plate.
  • the micro-switch opens stopping the motor as explained.
  • a garbage compactor including:
  • a sleeve open at each end for receiving garbage to be compacted and being adapted slidably to fit inside a garbage bag against a bottom of the latter
  • a base assembly adapted to receive the sleeve and garbage bag, the assembly having:
  • the sleeve being removable from the bags so as to leave the bag filled with compacted garbage.
  • a garbage compactor as claimed in claim 1 in which the sleeve tapers upwards.
  • a garbage compactor as claimed in claim 1 including rollers for supporting the base assembly for movement between a position beneath the pressure plate and the position spaced therefrom.
  • a garbage compactor as claimed in claim 1 including rollers for supporting the base assembly for movementbetween a position beneath the pressure plate and the position spaced therefrom.
