William B. Purvis

Improved Fountain Pen - patent #419,065 1/7/1890

William Purvis of Philadelphia invented and patented improvements to the fountain pen in 1890. William Purvis made several improvements to the fountain pen in order to make a “more durable, inexpensive, and better pen to carry in the pocket.”

Purvis used an elastic tube between the pen nib and the ink reservoir that used a suction action to return any excess ink to the ink reservoir, reducing ink spills and increasing the longevity of the ink. Fountain pens were first patented as early as 1809.
