ABSTRACT:
The invention pertains to apparatus for forming signs with a motor driven router. A frame defines a surface for supporting the sign panel to be routed, usually wood, and for supporting the letter forming templates. A carriage linearally movable upon the frame supports a polygonal, four-sided linkage, a template follower is mounted upon one of the links, and the router is also link-mounted. By varying the position of the linkage pivot points relative to each other, and the location of the template follower, a variety of letter styles can be produced from a single template, and a characteristic of the apparatus lies in the excellent visibility provided of the router during operation.
