For this reason in 1927 was created a second version of the filling system, in which the outer barrel was anchored conventionally to the nib assembly, and in its place was used to generate depression a second metal tube placed between it and the inner barrel. The depression system was anchored to the bottom of the pen which was a blind cap, in this way it was sufficient to unscrew the bottom of the pen to perform the loading, which at this point could be performed with one hand.

La [[Chilton]] però non sembra essere l'unico produttore ad aver utilizzato questo sistema, infatti un sistema sostanzialmente identico denominato [[Compressor]] era stato inventato dalla [[Montblanc]] nel 1923 (brevetto {{Cite patent|DE|400356}}) ed utilizzato dal 1924 al 1929 per alcuni modelli, che però vennero commercializzati su scala ridotta (principalmente in Francia) e non riscossero un successo significativo.<noinclude>

The [[Chilton]] however does not seem to be the only manufacturer to have used this system, in fact a substantially identical system called [[Compressor]] was invented by [[Montblanc]] in 1923 (patent {{Cite patent|DE|400356}}) and used from 1924 to 1929 for some models, which however were marketed on a small scale (mainly in France) and did not have a significant success.<noinclude>
