  • Patent number: 6082723
    Abstract: The present invention relates to a device for holding tile during cutting to obtain defined angles, preferably 45.degree. angles. The present invention further encompasses a method for using such a device in combination with a table-style tile cutter, preferably one using a roller tray with a lip, to cut defined angles into various orientations of tile and, more specifically, tile caps. The device comprises a base having a bottom and at least two straight edges that meet in a right angle in a corner of the base. In its preferred embodiment the base includes two grooves. One of the grooves includes a curved section shaped to mirror and support the concave side of the curved nose of a standard bullnose tile cap. The other groove includes a curved section shaped to mirror and support the convex side of the curved nose of a standard bullnose tile cap. These grooves allow for holding and supporting tile as aligned by the base for cutting pre-defined angles into various orientations of the tile.
