The patent system in the United States is one of the most important foundations for progress and innovation and was one of the driving forces for industrial expansion in the 19th century. The system gives inventors legal protection for their ideas and empowers innovators to innovate. Some of these inventions from 1864 might seem laughable now, but all of them tried to answer a need or want of some kind, needs that we still have 150 years later. Some were ridiculed back then as well: Sylvester Marsh’s cog railway up a mountain for tourists was considered ridiculous at the time, and one New Hampshire legislator thought that Marsh would be as likely to build a railway “to the moon.” But sometimes inventors can, as the saying goes, “laugh all the way to the bank.”
