170,141. Evans, F. July 28, 1920. Reservoir pens.-In a stylographic reservoir pen of the type in which a wire stylus is resiliently connected to the feed-bar, the feed-bar is made of such shape that the ink is divided into two or more separate columns other than round in cross-section, to avoid the formation of air-locks. In the form shown, a feed-bar a with flat faces a1 fits across the interior of the point-section d, and the wire stylus c extends through a longitudinal hole b in the bar a and is formed into a spiral coil c2, the free end of which is attached to the bar a.
