1. A device for layout of objects or installations on a floor or other generally horizontal surface, along two angularly related lines on the floor or surface, comprising:
- a platform or housing having a reference surface with means for holding the platform or housing in a position with the reference surface substantially parallel to the floor or other surface, a light beam generator producing at least two beams of visible light at a desired angle relative to one another, the beams being collimated at least in one axis and the beams being generally parallel to the reference surface, cylinder lens means in the path of at least one of the two beams, for spreading the beam into a fan of light essentially perpendicular to the reference surface, adjustment means connected to the cylinder lens means, for enabling manual adjustment of the cylinder lens means up or down relative to the reference surface, so as to enable steering of the fan of light to direct it higher or lower, so as to form lines on the floor or other generally horizontal surface or on one or more adjacent walls or vertical surfaces, and means on the platform or housing for marking or sighting on the floor the intersection of the two beams and of the two fans of light.

Abstract
An apparatus and method for generating two or more visible lines of light on a floor for the purpose of facilitating the layout process used in construction. The apparatus comprises a light beam generator producing two or more beams of light at 90° to each other and in a plane parallel to the plane of the floor. Subsequently cylinder lenses on the apparatus spread the beams and position them on the floor or target providing visible reference lines.
