The system was mainly used by A. A. Waterman who around 1902 acquired a patent (nº US-744642, attributed to Harry W. Stone) relating to it. Other companies introduced similar systems, or inspired by the same principle of rotating the bottom of the pen to squeeze the tank, such as the leverless of the Swan. A very particular version of this type of loading was used on a prototype pen of the Nettuno never marketed.
