November 19, 1912 - William B. Purvis of Sharon Hill, Pennsylvania shared patent number 530,710 for an improved Electric Railway System. This invention caused the third rail to be only energized when the railcar was passing over it, thus si...gnificantly reducing the chances of people being injured by coming into the contact with the third rail. Purvis had previously received patent number 419,065 on January 7, 1890 for the fountain pen. That invention made the use of an ink bottle obsolete by storing ink in a reservoir within the pen which was then fed to the tip of the pen. Over his lifetime, Purvis received nine additional patents. He is also believed to have invented, but did not patent, several other devices. Not much else is known of Purvis’ life.
