ABSTRACT:
A plunger-mounted pin moves axially in the tubular stylus projecting from the front end of a stylograph barrel. Ink is supplied to the stylus from a reservoir in the barrel through a continuous capillary conduit system partly constituted by an annular gap between the plunger and a feed bar in which the plunger is axially movable. A portion of the conduit system by-passes an air chamber behind the plunger.
