The limitations of the quill pen moved inventive people of the times to come up with a better writing instrument. Thus the design for the 'fountain pen' arose after over a thousand years of using the quill pen.
Noting the natural ink reserve that could be found at the bottom of the hollow channel of a bird's feather, inventors of the early fountain pen tried to simulate this by creating a mechanism that could store ink within a long thin barrel. A pointed nib was to be added to the tip of this barrel through which the ink would travel from the barrel to the paper.
Rough and unstable, the old fountain pen design was further developed, improved and later patented by Lewis Waterman. Waterman's fountain pen was made up of three parts — the nib, the reservoir which stored the ink, and the feed which controlled the flow of ink from the reservoir to the nib. 
Inventors of the time, tried to outdo one another in coming up with the best and less messy means to hold the ink inside the fountain pen.
