Abstract
A preset brake device is disclosed for use with line drawing machines, drafting machines, and the like. A preset input station is disposed on a guide rail of the drafting machine, etc. A movable body on the guide rail holds a line drawing instrument. A preset distance is entered into the preset input station, the preset distance representing a desired distance of movement of the movable body along the guide rail. As the movable body is moved along the guide rail, when the distance traveled by the movable body equals the preset distance, an electro-magnetic brake automatically arrests the movement of the movable body along the guide rail. Two displays are included. One display on the preset input station displays the preset distance. The second display will display the distance traveled by the movable body along the guide rail.
