Abstract
1,078,681. Making pens. I.R.C. Ltd. March 15, 1965 [March 17, 1964], No. 11280/64. Heading B3A. [Also in Division B6] The ball 12 of a ball-point pen is initially inserted into a cylindrical cavity formed in the pen tip. The ball is positioned by a stop 19, Fig. 1 (not shown), while the walls of the cavity are constricted around the ball in a conventional manner by a conical die 20. This initial operation forms a base seat 14 and a lateral seat 15 of part spherical form. A second operation is to apply a hollow cylindrical die 22, Fig. 2 (not shown) to the forward end of the nib, which die exerts an external pressure at a plane 23 located at a distance approximately one ball diameter to the rear of the ball centre. This operation enlarges the lateral ball clearance along the lateral seat 15. A third operation is to push the ball 12 outwards from the socket a distance equal approximately to one-tenth of the ball diameter. This is achieved with a pin 24, Fig. 5 (not shown), introduced from the rear through the ink feed duct 17, and results in a further enlarging of the lateral ball clearance. The finished ball-point nib is characterized in that when the ball 12 is pushed along the longitudinal axis of the pen into contact with the base seat 14, there exists a clearance between the ball surface and the lateral seat 15 Fig. 6, which in all transverse sections normal to the longitudinal axis of the pen nib forms a circular annulus of uniform width and in all longitudinal sections containing said longitudinal axis increases in width from the lower edge of the lateral seat towards its upper edge.
