Abstract

797,032. Reservoir pens. GOSSIAUX, W. June 28, 1956 [June 28, 1955], No. 19990/56. Class 146(3) A retractable ball-point pen comprises a pair of cams 11, 12 which define the limits of movement of an intermediate part 8 which is movable longitudinally with an ink reservoir, the intermediate part having two cam faces 9 and 10, a push button or sliding weight for causing longitudinal movement of the reservoir 2 against a spring 4, the cams 11, 12 being so arranged that longitudinal downward pressure on the reservoir disengages the teeth of the upper cam 10 of the intermediate part 8 from the teeth of the upper cam 12 and the teeth of the lower cam 9 of the intermediate part engage the teeth of the cam 11 to cause rotation of the reservoir, release of such pressure permitting the spring to move the reservoir into either a retracted or extended position. As shown, the cam surface 12, Fig. 4, comprises four teeth, two being large teeth 30 having sloping surfaces 22 and vertical faces 23. and two small teeth 24 having sloping faces 25 and vertical faces 26, thus providing deep hollows 27 and shallow hollows 28. The cam 10 comprises two teeth 19 having sloping faces 20 and vertical faces 21. The cam 9 has four teeth 13 provided with vertical faces 15 and sloping faces 14. The cam 11 comprises teeth 16 provided with sloping faces 17 and vertical faces 18. In operation, the press button 6, Fig. 1, is depressed thus disengaging the teeth 19, Fig. 4, from a hollow 27 or 28 and causing the teeth 13 to engage the teeth 16 thus rotating the part 8 a fraction of a turn. As a result, a tooth 16 which previously engaged a deep hollow 27 is positioned in alignment with a shallow hollow 28 or vice versa. Thus on release of the button 6, the part 8 and reservoir 2 are pressed rearwardly by the spring 4, into either a retracted position in which the ball point 3 is within the barrel 1 or an advanced position in which the ball point 3 projects beyond the barrel 1. In a modification, not shown, the push button may be replaced by a weight slidable in the cap 7.
