Definitions

• the present invention relates to an apparatus for compress ⁇ ing voluminous mass , especially household waste, comprising a cylinder with a feed opening for the mass and a driven, reciprocating piston .
• Sanitation vehicles currently in use may be divided into tw types: those that compress the waste and those that do not.
• the former type all share the drawback that the compressin equipment is heavy, thus reducing the weight load capacity of the vehicle, as well as being very expensive.
• This type of vehicle is also ill suited for operation by a single person, as the sanitation worker must ordinarily go to the rear of the vehicle to deposit the rubbish sacks. Normally, therefore, such vehicles are manned by three persons, one driver and two workers for fetching the garbage and placing it in the vehicle. This is unduly labor-intensive, and therefore expensive. Vehicles of this type are also heavy and noisy, thus disrupting the environment, and they may also have problems getting through on small, poorly surfaced roads.
• the object of the present invention is to provide an apparatus for compressing voluminous mass, especially house ⁇ hold waste, which is simple, inexpensive, ' requires little space, can be mounted and utilized in conjunction with an ordinary truck with high side frames, and which also permits the truck to be loaded from the side of the vehicle.
• the opening of the pipe faces substantially upwardly when the apparatus is in position for use.
• a further feature of the invention is that the pipe has a curvature of between 60° and 120°.
• the radius of curvature of the pipe is equal to or insignificantly larger than the pipe diameter or the diameter in the plane of curvature.
• Figure 1 schematically illustrates the apparatus in side view and partial cross section.
• FIG. 2 shows the apparatus from above
• Figure 3 shows the apparatus mounted on an ordinary truck.
• the apparatus of the invention consists of a cylinder 1 with a compression piston 2 which is driven to and fro by a hydraulic cylinder 3.
• a feed opening 5 is provided for introduction of the mass to be compressed, said mass comprising mainly sacks filled with household waste.
• a cover 6 is provided which automatically closes the opening 5 when the piston is activated for compressing the waste.
• a curved pipe 7 Joined to the outlet end 4 of the cylinder 1 is a curved pipe 7 whose external radius of curvature is equal to or somewhat larger than the diameter of the pipe in the plane of curvature. In use, as seen in Figure 3, the opening 8 of the pipe 7 faces upwardly.
• the piston may be formed as shown in Figure 1, as a conven ⁇ tional piston with a top surface and skirt 2*.
• the piston could alternately be formed as a plate where the skirt is replaced by guide ribs permanently welded to the plate.
• the curved pipe 7 has somewhat larger dimensions than the cylinder 1, so that an offset 9 is formed between the cylinder and the pipe.
• a similar offset can also be arranged on several sides of the cylinde The purpose of the offset is to prevent compressed rubbish which is inside the pipe from being pressed back into the cylinder chamber.
• the feed opening 5 is provided in connection with a similar opening in the side frame 10 of an ordinary truck.
• the sanitation worker can deposit the garbage sacks 11 at the side of the vehicle instead of having to go around to the rear of the truck.
• T loading opening is always at a suitable lifting height.
• the apparatus is mounted on the truck bed of an ordinary truck, and takes up very little space. In areas in which the garbage is fetched only once or a few times a week, the truck can be used for other kinds of transport on the days it is not needed for carrying rubbish.
• the compressing apparatus of the invention differs from prior art devices of this type in that it compresses only one garbage sack 11 at a time. This requires less power.
• the apparatus can be constructed simply and inex ⁇ pensively.
• Another reason that the forces are larger on the conventional compressing devices is that the force of compression increases gradually as the amount fed into the apparatus increases, because the garbage is compressed in a closed compartment, a container. Since the outlet of the curved pipe 7 faces upwardly, the necessary compression force will remain the same at all times.
• the garbage sacks are uniformly compressed to the desired degree by being pressed through the curved pipe and are pushed in an upward direction from the outlet of the pipe.
• the curved pipe has a bend of somewhat more than 90 , in this case about 110 , and the direction of egress will be backwardly/upwardl .
• the compressed garbage sacks are thus pushed in a direction in which they will not encounter any fixed obstacles. What will occur in practice is that a heap or hill of compressed sacks will accumulate around the compression apparatus at the front section of the truck bed. As the hill grows, a slide angle will gradually form, and when new sacks continue to be fed into the compressing apparatus and are pushed upwardly through the outlet of the curved pipe, the sacks will slide backwardly toward the opposite end of the truck, relative to the location of the compressing apparatus. The truck bed will gradually become filled, with the load being higher at the front of the truck bed, thereby obtaining a favorable distribution of the load.
• the compressing apparatus may conveniently be connected to the normal hydraulic system of the vehicle.
