Abstract:
1. A mechanical pencil, comprising: a grip barrel including a pencil end, a proximal end, and an outer surface, the grip barrel having an opening in the outer surface; a wheel rotatably mounted in the grip barrel around a wheel axis, such that a portion of the wheel extends into the opening such that is rotatable by a user; a chuck disposed within the grip barrel such that lead placed in the mechanical pencil is directed through the chuck, a slide member for holding a piece of lead, the slide member being slide-ably disposed within the grip barrel and operably connected with the wheel, the slide member also being operably connected with the chuck such that rolling the wheel causes the slide member to move forward and backward, wherein moving the slide member forward causes the chuck to advance the lead from the pencil end of the grip barrel and moving the slide member backward causes the chuck to slide backward and over the lead, thereby leaving advanced lead extending beyond the pencil end of the grip barrel.
