Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
167 words
A carpet cutter comprising a base adapted to be drawn across the floor and having a plate that fits under the flange of an anchoring strip about which the edge of the carpet is to be folded so that the edge of the plate forms a guide for the cutter, a generally vertical frame mounted on the base and having opposed ends and generally flat vertical surfaces, a pair of horizontal slots in the frame extending toward the center of the frame, one from each end and disposed above the base, a pair of blades provided in the frame between the flat vertical surfaces and with one blade intersecting each horizontal slot, said blades lying in a plane parallel to the edge of the plate and spaced from said edge a distance which causes the cut made by either blade to form a margin on the carpet that can be folded under the flange, and a handle for manually engaging the cutter and carried on the frame.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
55 words
A carpet cutter as described in claim 1 further characterized by a pair of blade slots in the frame between the vertical surfaces for supporting the blades, each of said blade slots being inclined to the vertical so as to support the blades at inclined positions with respect to the horizontal slots in the plate.
