ABSTRACT:
An engraving machine utilizing an elongate guide letter holder, and an adjacent workpiece holder adjustably disposed essentially parallel thereto. A movably mounted router assembly, comprising a stylus and a relatedly movable router means, is operatively disposed over such holders such that an operator grasping the stylus and tracing selected guide letters disposed on the guide letter holder brings about like movements of the router with respect to the workpiece mounted on the workpiece holder, with the bit of the router being caused to cut the selected letters into the workpiece. Advantageously, each of the holders utilizes a rapidly operated locking means that simplifies the task of removably securing the selected guide letters and the selected workpiece in a desired, aligned relationship on their respective holders. By virtue of the fact that the principal components of my machine can be easily placed in a preascertained relationship with each other, my invention lends itself to use with a book of precalculated tables that serve to further reduce setup time, even when workpiece size varies from piece to piece. My invention also comprises a novel method of rapidly making signs of desired size and content, prepared by reference to such book of tables.
