Abstract
1,224,382. Propelling pencils. TSAN-CHANG KUO, and SHAN-MU HONG. 25 June, 1968, No. 30205/68. Heading B6P. A fluid cylinder 4 is screwed into the rear of a barrel 2 so that fluid pressure moves piston 42 down an inner barrel 3 thereby propelling the lead 6 forward. The pencil of Fig. 1 is disposable, but that of (Fig. 2) has provision for replacing the lead and storing spare leads between the inner and outer barrels. As an alternative, the fluid can be replaced by solid particle, either in the form of spheres (147, Fig. 3) or cylindrical rods (247, Fig. 4), which particles are fed one after the other into the bore behind the lead.
