Abstract:
A device comprising:a hollow casing of such dimensions as to be held in the hand, said casing having inner and outer surfaces, a forward end, a rearward end, and a longitudinal extension/retraction slot through the casing, which slot has forward, medial, and rearward latch openings;a forward tip having a rearward base and a forward apex, the tip being affixed to the forward end of the casing, which tip contains a central axial passageway;a barrier fixedly located inside the casing approximately one quarter of the distance from the forward end to the rearward end, which barrier contains a central axial passageway;a forward work piece which is a member selected from the group consisting of 1) an ink cartridge having a forward end, a rearward end, an outer surface, and a writing point at the forward end, 2) a stylus, and 3) a tool rod having a forward end, a rearward end, an outer surface and a turning tool on at least one end, wherein the forward work piece has a spring retainer protruding radially outwardly from the outer surface of the forward work piece, the forward work piece being of such size as to fit freely through the central axial passageways in the tip and the barrier without excessive play;a coil spring around the forward work piece, which coil spring has a forward end and a rearward end, the forward end of the spring resting against the rearward base of the tip and the rearward end of the spring resting against the spring retainer, which spring urges the forward work piece rearwardly;a rearward endpiece affixed to the rearward end of the casing, which rearward endpiece contains a non-circular central axial passageway;a rearward tool rod containing a forward end, a rearward end, and a turning tool on at least one end, the tool rod being of such a size as to fit freely through the central axial passageway of the rearward endpiece without excessive play; andan extension/retraction pin located inside the casing and so sized as to slide along the inner surface of the casing, which pin contains a flat forward end and a rearward end, the rearward end being open and adapted to receive and hold the forward end of the rearward tool rod, the extension/retraction pin having an actuator guide pin springmounted therein in such a manner that when the actuator guide pin is depressed, the extension/retraction pin may be moved longitudinally along the extension/retraction slot in the casing to extend or retract the forward work piece through the central passageway in the forward tip and to extend or retract the rearward tool rod through the central axial passageway in the rearward endpiece and in such a manner that when the actuator guide pin is raised, the actuator guide pin must remain in a forward, medial, or rearward latch opening in the extension/retraction slot.
