Abstract
Abstract A method and apparatus for accurately locating a workpiece in positional relationship to a baseplate by projecting a light image having contrasting areas representing areas or features of the workpiece, or supports or clamps, etc., for securing the workpiece to the baseplate. The light image may be that of a template having representational markings or may be of the workpiece of supports, clamps, etc., to be secured to the baseplate. Instructions may be displayed simultaneously with the image and may appear on a separate screen. The template may be a photograph, i.e., print or transparency.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
126 words
Apparatus for use in securing a workpiece to a baseplate, comprising means to support the baseplate at a desired location, template-holding means to hold a template for defining a desired positional relationship to the baseplate of parts to be secured to the baseplate, and a diascope projector to project an image of said template onto the baseplate at said location, said templateholding means and the projector being arranged so that said image is in a predetermined positional relationship to the baseplate such that said parts can be secured at positions defined by the image in said desired positional relationship to the baseplate, and a screen onto which the image of instructions is projected by the projector simultaneously with the projection of an image of the template.
Claim 2
Dependent Claim
