Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
175 words
A scribing tool for cutting in a cut-in tile to fit into a cut in space between a full size tile and an upstanding wall generally perpendicular to said full size tile comprising a generally flat rectangular support plate having first and second edges, a substantially U-shaped channel disposed at said first edge of said support plate, at least two rotatable elements supported in said U-shaped channel, said rotatable elements disposed in the same plane as said support plate and partially extending out of said U-shaped channel to define a low-friction contact surface for enabling said support plate to ride along an upstanding wall generally perpendicular to said support plate, a support member disposed substantially at said second edge of said support plate, a scribing blade supported by said support member and extending beneath said support plate and adapted to scribe a cut-in tile partially disposed beneath said support plate as said support plate is moved along said wall and handle means connected to said support plate for moving said support plate along said wall.
Claim 2
Dependent Claim
