Parker Jointless

[2] In 1894 and following successive improvements to his 1889 patent, George S. Parker perfected the Curve Tubular Overfeed.

In 1896 this device would be improved and adapted as underfeed in the #2X Parker models according with Patent No.

This innovative element established a continuous capillary connection between the nib and the inner walls of the barrel avoiding some of the particular problems that, in its time, had the use of fountain pens; difficulty starting the ink flow when starting to write; poor, excessive, or uneven ink flow; ink dripping from the pen when the reservoir was not full or nearly empty, and ink overflowing through the section when the pen was reversed after use.

[3] In his constant search for improvement, Parker tackled the common problem of ink-stained fingers, eliminating the joint between the barrel and the section, whether it was this union by thread or by friction of both elements.

The Parker Jointless are not so distinguishable at the base of the barrel as they have added a zero as first figure over the equivalent models with joint old style.
