Toothbrush Patent- Historic Bathroom Patents Series


In the past 50 years or so, we've become so accustomed to our technology that we hardly even notice it any more. It's hard to believe that some things we take completely for granted are actually relatively recent inventions.

A surprising number of these inventions can be found in your average bathroom. For instance, consider the lowly toothbrush. The patent for a toothbrush with interchangeable heads came along in 1893. This plaque bears the original US Patent Office drawings of the brush, along with the technical description of exactly how it works. This would look fantastic in a Craftsman or Rustic-themed room, and would really appeal to engineers, technicians, scientists, inventors or anyone with a sense of history.
