Adjustable spirit level for tile and cabinet installation

Abstract

A spirit level for the installation of tile and cabinets includes a rigid body having upper and lower parallel planar surfaces separated by a first predetermined width. The body includes a bubble vial oriented to verify the orientation of the level. An auxiliary edge portion has a planar top surface and lower supporting edges parallel to the top surface separated by a second predetermined width. Means are provided for removably attaching the auxiliary edge portion to the upper planar surface of the body, thereby providing a level having two standard widths corresponding to industry standard tiles. A series of evenly spaced holes are provided for removably securing the body to a flat surface. The ends of the body include parallel planar end surfaces normal to the upper and lower planar surfaces. A threaded hole is provided penetrating the surface of the body. A threaded setscrew is provided to engage the threaded hole and to bear upon the auxiliary edge. An adjusting notch is provided with a recessed planar surface is disposed at either end of the body at the planar lower surface. A threaded opening is provided centrally located in the recessed planar surface. A threaded bolt to engage the threaded opening is provided and is of sufficient length to extend outwardly from the threaded opening to a point beyond the planar lower surface when unscrewed from the nut so as to adjust the level to uneven surfaces.
