Abstract
A four part writing instrument mechanism includes a one piece synthetic anchor bushing and a one piece synthetic cartridge shuttle which are axially movable with respect to each other. A metal driver with a helical section engages a groove in the shuttle for moving the shuttle axially. The driver is axially fixed but rotatable on the anchor bushing. A writing cartridge, such as a ball point pen cartridge, is fixed to the shuttle and has a writing point which is extendable from and retractable into an opposite end of the anchor bushing.
