The Schrader Valve

August Schrader immigrated from Hanover, Germany, to New York in 1843.  Within a few years he started a small company making brass fittings for the rubber industry, which had been started only a few years before. 

In l890, pnuematic tires were in use on the bicycle racing circuit, and soon bikes with pnuematic tires began winning the races.   A tire manufacturer asked Schrader to design a better air valve than the one they were using, and Schrader did so.  Schrader and his son George applied for a patent on their design in 1893, and made many improvements over the years.  Every car today uses Schrader valves to keep the air in the tire, whether tube or tubeless tires.  Most bicycles today use Schrader valves, with certain tubes using an alternative valve, the Presta valve.  The Schrader valves used  today are very similar to the 1893 version.

    August Schrader was quite a guy.
    Well, I guess I’m continuing his tradition
    because I just invented a whole new car.
    Oh, and yes, it uses Schrader tire valves!

    It’s great that more people are focusing on making better environmental choices. Plus technology is making it more economical now, and that’s what people really notice. Wind energy, solar power, hybrids and zap EV’s, our choices are good. There are now electric cars being sold everyday, you just plug it into a regular power outlet. When people test drive them they say it’s far more fun to drive an EV.

    My relatives were geniuses but the Schrader Valve was invented more than 100 years ago.
    You would not believe what I’m working on in my small laboratory now.

    Also, I’m setting-up a non-profit foundation
    to study beneficial technology to solve problems and make everyone’s life easier
    and better. You can donate anytime.
    For example, if the foundation can perfect superconductors, your electric bill might only be $2.00
