  • Patent number: 4835874
    Abstract: A hand-held marking device for drawing upon a paper or other surface. The device includes a housing having a hole opening to the surface and enclosing a motor, batteries for the motor, and a switch. The motor drives a gear train, which includes a pinion gear axially connected with the motor and a spur gear geared with the pinion gear. A holder gripping a pencil or pen is positioned over the hole so that the holder rotates about a horizontal pivot pin downward so that the pen or pencil comes into contact with the paper or surface to be marked by force of gravity. The paper is in a horizontal plane and the pen is in a vertical orientation. The holder is secured to the inner rim of the spur gear. The swivel member can be aligned into one of a plurality of locking recesses along an arced groove eccentrically oriented relative the center of the spur gear. When the motor is turned on and the marking device is moved manually, the pen draws a continuous spiral.
