Patent attributes
An improved rotatable wedge spacer to be removably positioned in a gap between opposing upper and lower surfaces (e.g., tiles) that are being bonded (e.g., by means of mortar) one above or adjacent the other to a flat surface (e.g., a wall or a floor). The spacer includes a curved (e.g., circular) body having a thin tip at one end and a thick tail at the opposite end. The height of the circular body between an upward sloping top surface thereof and a flat bottom surface increases from the thin tip to the thick tail. A series of flat load-supporting plateaus having predetermined increasing heights are regularly spaced from one another along the top surface so as to lie parallel with the flat bottom surface. With the flat bottom surface of the wedge spacer seated upon the lower tile, the curved body is rotated within the gap until one of the flat load-supporting plateaus along the top surface engages the upper tile. Accordingly, the curved body of the rotatable wedge spacer will fit flush and maintain the gap between the tiles as the mortar cures.
