Abstract

708,633. Reservoir pens. KOVACS, T. Jan. 16, 1951 [Feb. 2, 1950], No. 1219/51. Class 146(3) A feed bar 3 is provided with a tapering air duct 7 having tapering capillary ink grooves 8 on the side adjacent the knib 4, the air duct being in communication with annular chambers 11 and 12 connected by a capillary groove 18, these chambers having a greater' capillary potential than the air duct at their level. Longitudinal chambers 9 and 10 are provided in the feed-bar for storing ink overflowing from a reservoir 2. Air to replace ink used is supplied to the reservoir 2 through the air duct 7, an annular groove 16, and a longitudinal groove 17, but when the chambers 11 and 12 are filled with ink, a gap 15 communicating with the groove 16 is filled with ink, thus preventing air entering the reservoir. In these circumstances, ink filling the chambers 9 and 10 and chambers 11 and 12 must be emptied before replacement air can reach the reservoir 2. The sizes of the ink duct 7 and chambers 9, 10, 11 and 12 are such that overflowing ink fills the air duct 7 last, while ink from the air duct 7 is used first, then ink from the chambers 9 and 10, then ink from the chamber 11, and finally ink from the chamber 12.
