Abstract

1,234,523. Writing instrument; erasers. PARKER PEN CO. 5 Sept., 1969 [31 Oct., 1968], No. 44035/69. Heading B6P. A writing instrument is provided with a self contained replaceable cartridge 14, a pointactuating mechanism 16, an eraser assembly 18, and a removable reciprocable cap 20. The cartridge is either a ball-point reservoir spring biased into the retracted position, or a pencil magazine with a step-by-step feed mechanism as described in Specification 1,194,259. The rear of the cartridge is provided with a cam member 38 which co-operates with a plunger 61 of the point actuating mechanism to be successively rotated into the projected and retracted positions defined by stop members 70 formed on the inside surface of the rear barrel portion 56. Mounted atop the plunger 61 is a cupshaped eraser holder 88. The reciprocable cap 20 has an inner shell 96 which abuts the pointactuating mechanism.
