Abstract

There is disclosed a device for the duplication of irregular shapes that must be reproduced on a surface but cannot be traced directly on the surface. The device includes a stylus, a length of chain or the like attached to the stylus, and a duplicator attached to the other end of the chain. The duplicator contains a programmable memory, such as a RAM chip, and servo-type motor to vary the length of the chain as the program is run.
