Abstract:
A device is provided for transferring crayon or similar drawing material onto a surface. The device comprises an elongate tubular housing for housing a crayon, a transfer wheel, and a number of gears for rotating the crayon with respect to the wheel. The transfer wheel rotates about an axle riding on forks extending from the housing. An inner sleeve is located in the housing and contains the crayon. Gears located on the axle, fork, and sleeve rotate the sleeve when the wheel is driven along a surface. Rotation of the sleeve rotates the crayon, causing the transfer wheel to remove crayon material uniformly from the end of the crayon. Spring loaded offset locking rods press the crayon into engagement with the wheel and lock it in the sleeve.
