ABSTRACT:
The following specification discloses a universal guide or pattern for use with a panograph. The panograph can comprise a number of arms that are interconnected at hinge points that support a spindle having a cutting tool for milling or cutting a circular, ornate, or eccentric shape, as well as angles and lines. The spindle with the cutter correspondingly follows the movement of a stylus that overlies the universal pattern that is formed with an arm that guides the stylus in either a two or three dimensional pattern. The pattern is formed in part on a plate having a centrally oriented pin or support post that holds a rotatable arm having a scale thereon. The rotatable arm has a pair of stops that can be set along its length at different locations with respect to the scale. The panograph stylus can be implaced within a stylus holder that moves along the arm between the stops or within the stylus holder that is secured by a set screw. The base plate is provided with a number of various angularly oriented openings so that the arm can be turned to the different angles and locked in the openings. Thus, the different angles of the holes formed on the plate, as well as the different radial locations of the arm and the stylus holder provide whatever conformation is desired on the work. In this manner, the stylus can move in a pattern that is pre-established with respect to a number of various movements without the requirement of a specific pattern for each particular conformation that is to be milled or cut.
