World's First Trikes, 4-Wheel Bikes in 19th Century?

This rail trike came about in the late 1800's. As I research this and the Irish Mail 4-wheel bike around the turn of the last Century, I am not finding much on line. If anyone can help with any information so I can rewrite the beginning of the Recumbent's history at http://bikeroute.com/WhyBent.php, I can be reached at awakeagainmartin @ gmail.com
