ABSTRACT:
The compacting breaker press breaks and compacts waste into small-sized nearly parallelepiped-shaped pieces, which can pass through small-sized pipes for collection. The press includes fixed guides and twin opposing pairs of parallel plates spaced from each other and slidably mounted on the guides. The external plate and internal plate of each pair are movable relative to each other, the internal plate being connected by springs with the external plate. Substantially equal, parallelepiped-shaped pistons are mounted on both external plates and extend through holes in the internal plates. These pistons have flat interior-facing surfaces which lie in two common substantially parallel planes depending on which exterior plate the piston is attached to. Interiorly-directed extractors are attached to both interior plates. Each extractor has the same shape as that of a piston and has an interior-facing surface which lies in one of the two common planes to form two opposing flat continuous surfaces, when the pairs of the plates are separated as far as possible from each other. The press has means for moving the external plates, so that, when these plates are moved toward each other, the inner plates slide toward the external plates on contact with a stop device, the pistons extend from the extractors to form recesses and break the waste and then compact the waste in the recesses into small pieces.
