Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
151 words
A tire disintegrator for grinding defective tires into a residue for recycling, said disintegrator comprising: a first set of spaced, axially aligned abrasive wheels, a second set of spaced, axially aligned abrasive wheels, said first set and said second set being mounted on parallel axle shafts, said axle shafts being spaced apart a distance greater than the radius of said wheels, means counterrotating each set downwardly and toward each other to frictionally retain tires places thereover in abrasive contact with said wheels, said wheels enclosed within a housing, said housing having a top opening in the top thereof through which tires may be inserted and a bottom opening at the bottom thereof through which tire residue may pass, a pair of side guides adjacent said top opening to maintain tires in a substantially upright position over said wheels, said tire guides being laterally adjustable to receive tires therebetween of various widths.
Claim 2
Dependent Claim
