Abstract

498,997. Fountain pens. BIRO, L. J. June 15, 1938, No. 17743. [Class 146 (iii)] In a fountain pen employing a rotatably-mounted ball 1 as the marking-element and a soft pulpy dye as marking-material, the dye being pressed against the ball by a piston 7, the piston-rod 11 is slidable but not rotatable relatively to the piston and a spring 10 is arranged between the piston and the rod. The piston-rod screws into a nut 14 rotatably mounted in the end of the barrel. When the piston is screwed forward, the dye presses the ball to seal the aperture at the front end of the barrel except when the ball is applied to a surface during use.
