  • Patent number: 4084569
    Abstract: The invention relates to tile cutters and provides a tool for cutting glass and ceramic tiles. The tool can be used both to guide a scriber for scoring the surface of the tile and also to provide the necessary bending stress to snap the tile along the score line. The tool comprises a base member and an arm hinged thereto, a ridge being formed on the top of the base member. The arm includes a slot for guiding the scriber and at least one pair of shoulders located on either side of the slot. The slot is held parallel to the ridge so that the shoulders are located on either side of the ridge. When pressure is applied to the arm with a tile resting on the base member, bending stress is applied to the tile by the ridge acting on one side of the tile and the two shoulders acting on the other side of the tile.
