Abstract
A pencil eraser assembly having elongated hollow eraser sleeve 11 formed to align in elemental parallel spaced relationship with both frustum shaped segment 18 and portion of cylindrical barrel segment 19 of pencil 16. Sleeve 11 having an opening adjacent the end point of frustum segment 18 for holding elongated eraser plug 12 within sleeve 11 and adjacent to pencil lead 17 of pencil 16. Eraser plug 12 can be extended out of sleeve 11 or retracted into it by means of barbed piston 13 impaled within the other end of eraser plug 12. Push tab 14 attached to piston 13 extends out through an elongated slot in sleeve 11 to provide a means of sliding piston 13 and eraser plug 12 within sleeve 11.

For use with a pencil having a generally cylindrical barrel segment and an attached frustum shaped segment and a pencil lead extending out from the point end of said frustum segment, a pencil eraser which comprises:
- an elongated hollow eraser sleeve formed to align in elemental parallel spaced relationship with a portion of the cylindrical barrel of the pencil and to extend in elemental parallel spaced relationship along the frustum shaped segment of said pencil to a point adjacent to the point end of said frustum segment, said sleeve having an opening at the end adjacent to the point end of the frustum segment for receiving an elongated eraser plug, and further having an elongated slot running substantially the length of and along the longitudinal axis of said sleeve;
- an elongated eraser plug slidably retained within said sleeve;
- means for extending the eraser plug out through said sleeve opening slidably disposed with said sleeve;
- and
- means for attaching the sleeve to the pencil.
