A notable variant of the safety filler is the peculiar filling system adopted by Moore for its Non-Leakable pens, for which three distinct patents were filed, one in 1893 (nº US-501895) and two in 1896 (nº US-567151 and nº US-567152). The principle is always to use a recessed nib assembly, but in this case instead of using a helical screw, there is a linear sliding type.
The system has, compared to the traditional safety filler, the advantage of an enviable mechanical simplicity, in this case in fact the sliding of the nib group is achieved through the use of a sleeve placed on the bottom of the pen that is made to slide back and forth on the shaft of the same. At the bottom that closes the sleeve is hooked with a rod the nib group, which emerges through a gasket watertight from the bottom of the barrel, so it can be moved into writing position or returned to the body of the pen.
With the nib in the retracted position the pen can be loaded or closed like any other traditional safety, so much so that Moore sold its own pens leaving the factory already loaded with ink, as further evidence to support the actual truthfulness of their name Non-Leakable.
The mechanical simplicity of the system, based on the simple linear sliding of a rod, is the strong point of this mechanism, much more robust and easy to made compared to the complexity of that used in the other retractable pens; all that was required was a good precision in the tolerances of the mechanical machining and good quality gaskets.
Oltre che dalla Moore il sistema è stato usato anche dalla Montblanc nei primi modelli Rouge et Noir, portato quasi certamente in Germania alla fondazione dell'azienda da Arthur Eberstein, che in precedenza aveva lavorato proprio per la Moore.
