  • Patent number: 6427569
    Abstract: A method and tool for repairing worn seams in sheet materials, such as linoleum or vinyl floor coverings, is disclosed. The tool is a specially constructed, double bladed utility knife. The tool has dual cutting blades that are rigidly secured to the tool for precision cutting. The blades are set at a slightly divergent angle relative to one another, and the distance between the blades is adjustable. The tool may be used to repair a damaged seam in a floor covering as follows. First, the blades are set to span the widest portion of the damaged portion of the seam. Cutting pressure is applied and the tool is drawn along the seam to remove the damaged portion. The blades are then adjusted to a slightly wider-apart position, and the tool is used in a similar manner to cut a repair piece from a matching piece of material. The repair piece is then adhered to the floor and will fit snugly between the adjoining pieces of material to accomplish a perfect repair of the seam.

  • Patent number: 5209148
    Abstract: An "S" shaped, double-blade carpet cutter is provided which simultaneously cuts the edges of two adjacent, overlapped carpets from the back side, to provide closely matching, abutting edges which can thereafter be seamed. The lower carpet edge is inserted into one opening of the "S", and the overlapping edge of the upper carpet is inserted into the other opening of the "S". One blade is mounted on the first or top arm of the "S" and the other blade is mounted on the second or middle arm of the "S", and the blades extend perpendicularly out of the plane of the "S" and are aligned to cut along a single seam line. A handle is attached to the third arm of the "S" to allow the cutter to be pulled along the overlapped carpet edges.
