Crushing—breaking apparatus

A crushing—breaking apparatus, comprising a frame having side plates facing each other and spaced apart a predetermined distance, a first cutlery device provided in said frame, said first cutlery device comprising a plurality of first projection-shaped cutleries, a second cutlery device provided in said frame, said second cutlery device comprising a plurality of second projection-shaped cutleries, said plurality of second projection-shaped cutleries being disposed on said second cutlery device at locations offset relative to said first projection-shaped cutleries of said first cutlery device, first pivot means for pivotally supporting said first cutlery device, second pivot means for pivotally supporting said second cutlery device, said first cutlery device comprising a relatively upper and a relatively lower end, said second cutlery device comprising a relatively upper end and a relatively lower end, wherein said first pivot means is situated at least near said relatively upper end of said first cutlery device, wherein said second pivot means is situated at least near said relatively lower end of said second cutlery device, first abutment means effective for at times engaging said first cutlery device to thereby stop motion of said cutlery device about said first pivot means, second abutment means effective for at times engaging said second cutlery device to thereby stop motion of said second cutlery device about said second pivot means, first motor means operatively connected to said first cutlery device at an area thereof which is at least closer to said lower end of said first cutlery device than to said upper end of said first cutlery device, and second motor means operatively connected to said second cutlery device at an area thereof which is at least closer to said upper end of said second cutlery device than to said lower end of said second cutlery device, said first motor means being effective to pivotally move said first cutlery device about said first pivot means as to thereby move said relatively lower end of said first cutlery device toward said second cutlery device, said second motor means being effective to pivotally move said second cutlery device about said second pivot means and generally toward said first cutlery device, wherein said first cutlery device continues to so move toward said second cutlery device and said second cutlery device continues to so move toward said first cutlery device as to place said relatively lower end of said first cutlery device juxtaposed to said relatively lower end of said second cutlery device and to place said relatively upper ends of said first and second cutlery devices spaced from each other and defining an inlet for placing work to be crushed between said first cutlery device and said second cutlery device.
