ABSTRACT:
A combined writing instrument and eraser dispenser wherein a twist and click actuator (4) is rotatably and axially slidable within an outercasing (5). A portion of the twist and click actuator extends from within a tail of the outercasing enough to provide a grip (4c) for twisting and clicking. Ensconced within the twist and click actuator is an eraser carriage (2), which holds a long eraser (3). The eraser carriage has two raised projections (2b) which sit in two cut away grooves (4b) running longitudinally in the twist and click actuator, and thus the twist and click actuator and the eraser carriage are relatively nonrotatable but are relatively axially slidable. Thereadably engaged within the eraser carriage is a lead pipe (1) which could be the lead pipe of a mechanical pencil or the ink cartridge of a ball point pen. Relative twisting of the eraser carriage and the lead pipe causes a relative axial motion. The lead pipe has a noncircular cross-section (1b), near the front of the writing instrument, which is axially slidable through a noncircular throughput (5b) within the outercasing. The twist and click actuator rotatably, but not axially slidably, grasps the lead pipe with an inward semi-annular projection (4a) within its front end. The lead pipe and the outercasing are connected to a head assembly (6) particular to the writing instrument called for (pen, mechanical pencil, etc.) in the conventional manner.
