This patent is interesting in that I am not sure how it received a patent at all. This made the patent list in 1980 and if it had been 100 years earlier, it would have made sense. According to the patent law, the invention for a utility patent " must be new and novel". Called the 'Velocipede Railway Bike" it performs an obvious function to ride on rails designed for trains. I get it! But the bike is not new or novel, and the wheels to fit the track is not new, so what makes this a protected idea? The patent is also replete with a lot of drawings that also seem obvious, but they don't issues patents for drawing proficiency. If someone sees something that I missed, please let me know. All aboard here.
