Fountain Pens

The fountain pen contains a reservoir of water-based liquid ink. It uses an ink cartridge or a converter.

Patented in 1884. The fountain pen's design came after a thousand years of using quill-pens. Early inventors observed the apparent natural ink reserve found in the hollow channel of a bird's feather and tried to produce a similar effect, with a man-made pen that would hold more ink and not require constant dipping into the ink well. The fountain pen mechanism is composed of three main parts. The nib, which has the contact with the paper. The feed or black part under the nib controls the ink flow from the reservoir to the nib. The round barrel that holds the nib and feed on the writing end protects the ink reservoir internally (this is the part that you grip while writing).

All pens contain an internal reservoir for ink. The different ways that reservoirs filled proved to be one of the most competitive areas in the pen industry. The earliest 19th century pens used an eyedropper; by 1915, most pens had switched to having a self-filling soft and flexible rubber sac as an ink reservoir. To refill these pens, the reservoirs were squeezed flat by an internal plate, then the pen's nib was inserted into a bottle of ink and the pressure on the internal plate was released so that the ink sac would fill up drawing in a fresh supply of ink.
