ABSTRACT:
Disclosed is a tool for marking tiles having a predetermined thickness, so that the tiles may be cut precisely to enable them to be placed adjacent each other and spaced apart a predetermined, uniform, distance corresponding to the thickness of a desired grouting thickness. The tool includes a generally flat, elongated, rectilinear bar having a pair of opposed ends, a pair of opposed sides, and generally flat top and bottom opposed faces. A plurality of different sized slide elements are selectively used with the bar depending of the desired thickness of the grouting. Individual ones of the slide elements are adapted to be carried by the bar and movable along the length of the bar between the ends and removed from the bar by sliding off an end. Each of said slide elements have a body member which is supported by the top face and has a pair of opposed arms extending along and bearing against the sides. The arms have a height less than the thickness of the tile. Each of the arms has a finger which extends beyond the bottom face and inwardly beneath the bottom face. The fingers are of an equal, predetermined thickness which facilitates marking the tile so that, upon installation, adjacent tiles may be spaced apart said predetermined, selected distance. A screw type fastener extends through the body which, upon tightening, has an end bearing against the top face for holding the slide element in a selected position along the bar. The tool includes a plate attached to an end of the bar which has a straight edge and which is movable to different angular positions relative to the bar. This allows cutting the tile at an angle to fit next to angular walls.
