Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
57 words
A clipper comprising a pair of cutting heads, curved cutting edges carried by said heads for movement one toward the other along a path for cutting material inserted therebetween and means carried by said clipper for flexing said cutter to modify the curvature of said cutting edges in a plane transversely of the path of said movement.
Claim 2
Dependent Claim
57 words
A clipper comprising a pair of cutting heads, curved cutting edges carried by said heads for movement one toward the other along a path for cutting material inserted therebetween and means carried by said clipper for flexing said cutter to modify the curvature of said cutting edges in a plane transversely of the path of said movement.
Claim 3
Dependent Claim
53 words
A clipper according to claim 1 wherein each cutting edge is formed integrally with its associated cutting head, said cutting heads are formed of a resilient material and the last said means includes a pair of opposing channels slidably receiving said cutting heads and means for adjustably positioning said heads in said channels.
