Abstract
An improved glass breaking apparatus is of the type which includes a plurality of rotating breaking bars which are capable of breaking a glass bottle into small glass pieces and at least some larger glass pieces having a longest dimension exceeding a predetermined length. The improvement includes a pair of cylindrical rollers disposed below the plurality of rotating breaking bars and mounted for rotation in opposite directions about parallel, horizontal axes. The cylindrical rollers are spaced apart to provide a predetermined separation distance between the cylindrical outer surfaces thereof. The cylindrical rollers include an array of extensions about the cylindrical outer surface and are relatively disposed to cause the extensions of one cylindrical roller to be aligned with the cylindrical outer surface of the other cylindrical roller. Consequently, the extensions and the cylindrical outer surface of one cylindrical roller cooperate with the extensions and the cylindrical outer surface of the other cylindrical roller to break the larger glass pieces therebetween to reduce them into small glass pieces with a longest dimension which is less than the predetermined length.
