Filling systems |
The loading system called Touch Down by the company itself was introduced by Sheaffer in 1949 for the namesake models, and is nothing more than a more sophisticated reworking, carried out after twenty-five years (patent nº US-2610612), after 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.
