Abstract

989,658. Reservoir pens. SANFORD CORPORATION OF LIBERIA. Nov. 20, 1962 [Dec. 29, 1961], No. 43792/62. Heading B6P. In order that ink cartridges 26 of the same length may be used in pens having cartridge-receiving spaces 24 of different lengths, the cartridges are made of shorter length than the spaces 24 and a spacer device 28 is provided by means of which a cartridge can be properly positioned and held firmly in the different pens. The spacer 28 comprises two cylindrical parts 50, 52, joined by a part 48 and a tapering part 54, the part 50 being of slightly greater diameter than the part 52. The cartridge 26 has a plug 34 at one end the opening 42 in which is closed by a thin membrane before the cartridge is inserted in the pen. For use in a taperedbarrel pen, Fig. 2, the two parts 12, 14 of the barrel are separated, the spacer 28 is placed in the part 14 with the end 52 abutting against a rim 25, the cartridge is inserted, and the parts 12, 14 are reconnected so that the cutter nozzle 44 on the barrel part 12 will pierce the membrane in the opening 42. If a cartridge is to be employed in a pen with a shorter and cylindrical cartridge space, the part 52 of the spacer is broken off, and the remaining part inserted into the part 14 of the barrel with the spacer part 50 engaging the rim 25 (Fig. 3, not shown), the cartridge then being inserted and the barrel parts reconnected as before. The two parts 50, 52 have different diameters, so that by turning the spacer end for end it can be used in pens having different diameter rims 25.
