Abstract
A hand drawing machine which includes two spring-loaded spools. Each spool includes a length of flexible material, and each length of material is attached to a rigid stick or rod. The stick, which may be adjustable, includes a pair of stylus holders. The stylus holders can hold a marker or a tracing pin. Each of the spools has a gear portion that meshes with the other gear portion of the other spool. When a marker or tracing pin is moved a corresponding movement is made by the marker in the other stylus holder. The machine allows for the tracing of an image or for simultaneously drawing two copies of an image.
