ABSTRACT:
An apparatus for replicating three-dimensional articles which comprises a frame means for supporting, in parallelly disposed relationship, the article to be replicated and a blank workpiece. A parallelogram working frame is supported on the base frame means, with the parallelogram working frame being arranged for both longitudinal and transverse motion. The parallelogram working frame supports and carries a motor driven cutter assembly, and the cutter assembly includes a cutter head which is rotatably driven along a certain working axis. A laterally spaced stylus is provided for making contact with the surface of the article to be replicated. The parallelogram working frame carries a counterweight at the end opposed from the cutter assembly so as to accomplish ease of positioning, adjusting, and maintaining the cutter assembly in operative disposition. The apparatus further carries means for rotating the article to be replicated and the blank workpiece, with the arrangement being particularly adapted for replicating articles fabricated from wood, such as gun stocks and components of furniture.
