text: Excess ink in the nib drained back down to the reservoir by capillary action, making it less likely to spurt out into your pocket when the pen was not in use.
text: George S. Parker (1863–1937), founder of The Parker Pen Company, patented numerous refinements, including a simplified "self-filling" mechanism (1911), a leak-proof safety cap (1912), and a cunning feature he called the "lucky curve" (1911)—a bent tube connecting the nib of a fountain pen to the side wall of the reservoir, which ensured that any ink trapped in the top always drained back down again through capillary action, reducing the risk of a leak.
