  • Patent number: 5746126
    Abstract: This invention relates to a rubbish compression apparatus, comprising: a base plate; a main body, mounted on the base plate, into which the rubbish will be thrown; a roughly funnel-shaped compress tube, taking in the rubbish that has been thrown in; a compressing device, having a first pressing plate, which uses a threaded shaft; a shaft, which passes glidingly through the first pressing plate and the threaded shaft along their longitudinal axis; a second pressing plate, mounted below the first pressing plate on the low end of the shaft; and an anvil plate, mounted below an opening in the lower part of the compression tube. The second pressing plate is taken by the shaft to enter the compression tube and pre-compresses the rubbish.
