The loading system called Touch Down by the company itself was introduced by Sheaffer in 1949 for the homonymous models, and is nothing more than a more sophisticated reworking, carried out after twenty-five years (patent nº US-2610612), of the Chilton pneumatic filler system (whose patent, nº US-1528379, is mentioned explicitly). In fact, the operating principle is essentially identical, what changes is the way in which the pneumatic compression of the rubber sac inside the pen is carried out.
