The Advent of the Conklin Nozac: America’s Piston Filler 1931

Conklin saw itself as the innovator and catalyst for the move from eyedropper pens to self-filling pens because of Roy Conklin’s crescent filling system, based on his 1901 and 1903 patents. It was so simple to use. Press the raised crescent on the barrel to squeeze the ink sac inside, filling the pen. It became the first successful mass-produced self-filling pen and was in continuous production until the late 1920s. In that same timespan, the rest of the pen industry caught up and moved past Conklin’s invention, and the one-time market leader found itself playing catch up. Conklin introduced lever-fill pens in 1924 and streamlined pens in 1930, following the market trends set by other companies. The company needed something really new to break out from the pack and grow sales again. The company needed a hot new product to retake its position as a leading pen manufacturer.
