ABSTRACT:
An apparatus, suitable for household use, for cutting and breaking empty discarded frangible containers into small pieces of material to facilitate subsequent processing and recycling of those materials. The apparatus includes a manually operable loading bin for dumping containers (glass or plastic bottles and jars, metal cans, small cardboard boxes, etc.) into the wide upper inlet opening of a conical chamber. Motor-driven rotatable circular cutting blades, having sharp edges which project into the chamber through slots in the chamber wall, cut and break the containers descending through the chamber into small pieces of material (glass, plastic, metal, cardboard, etc.). The pieces exit the narrow lower outlet opening of the chamber into a selected one of several compartments in an adjustably positionable carousel below the outlet opening. The slots (and blade edges projecting therethrough) are arranged in three radially spaced apart vertical columns around the chamber wall. The slots in each column are vertically spaced apart. The cuttingh blades in each column are rigidly mounted in vertically spaced apart, eccentric relationship on a drive shaft mounted exteriorly of the chamber. One shaft is motor driven and drives the other two shafts through a pinion/ring gear mechanism. Containers descending through the chamber are squeezed, scored, cut and broken between the sharp edges of the cutting blades and the opposing cutting blades or opposing wall surfaces.
