Abstract
711,796. Reservoir pens. GOWLAND, J. P. Feb. 27, 1952 [March 2, 1951], No. 5134/51. Addition to 670,182. Class 146(3) A ball-point pen comprises an outer case or barrel 1 having, at one end a housing 2 for a writing ball 3 and containing a number of distinct reservoirs 8 each extending side by side within the barrel substantially longitudinally thereof, and a control member 6 extending longitudinally within the barrel and rotatable therein, the control member having an ink-control passage 9 therein adapted, upon rotation of the member, successively to establish communication between a duct 4 in the ball housing and a point near the outlet end of each individual reservoir. The control member 6 comprises a stem, rotatable in a bore 5, which is located on a bearing 6a in the barrel, and passes through a bore in a plug 10 and then partly into a cap 7 which serves to rotate the stem. The barrel 1 is provided with a number of radiallyarranged passages which form the ink reservoirs 8, these having open sides adjacent the stem 6. The passage 9 comprises a radial slot in the stem 6; a similar opposed slot 13 in the stem communicates with a bore 14 in the cap 7 to expose the upper end of the selected reservoir to the atmosphere. The plug 10 seals the upper ends of the reservoirs not 'in use. The barrel 1 and the slots 8 therein can be formed by a moulding process, and the dimensions of the slots are such that a viscous ink will be retained therein by capillary forces. Reference has been directed by the Comptroller to Specifccations 571,698 and 573,747.
