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.
Claims19
A drawing implement for transferring a drawing material onto a drawing surface comprising:
- an elongate tubular housing, having a first end portion and second end portion and a centerline running therethrough, for housing a rod of semi-solid drawing material;
- a material transfer wheel mounted adjacent the second end portion of said housing for rotation about an axis running perpendicular to said centerline of said housing for removing drawing material from said rod of drawing material and depositing it on the drawing surface;
- and
- means for rotating said rod of drawing material with respect to said wheel and about an axis parallel to said centerline of said housing.
A drawing implement for transferring a drawing material to a drawing surface, comprising:
- an elongate outer housing having a first end portion and second end portion and a centerline therethrough;
- a sleeve located within said housing, said sleeve having a first end portion and second end portion, said second end portion of said sleeve extending outwardly from said second end portion of said housing and having a gear thereon;
- a pair of forks, each fork having a first end portion connected to said second end portion of said housing and a second free end portion;
- an axle spanning said forks between their free end portions and extending perpendicular to said centerline of said housing;
- a transfer wheel located on said axle for contacting said drawing material and said drawing surface;
- gear means contacting said gear on said sleeve and said axle;
- and
- locking means for locking said drawing material in said sleeve.
A mechanism for use in transferring material from a rod of drawing material located in a drawing implement including an inner sleeve positioned in an outer housing comprising:
- a support member having a first end portion designed for selective attachment to said housing and a second free end portion;
- an axle spanning said second free end portion of said support member;
- a transfer wheel located on said axle for contacting said drawing material and a drawing surface;
- and
- means for rotating located on said member for connection with said implement for rotating said material with respect to said wheel.
