Tool time Tuesday. Every tire, or inner tube, has a Schrader Valve, also known as an American Valve. The valve was invented in 1891 and patented in 1893 by August Schrader. The valve system consists of a valve stem in which a valve core is threaded into. The valve itself is a spring loaded poppet valve that seals the valve stem with a rubber washer, keeping the air or, in some cases, liquid in the tire or tube. You need a special valve core tool to remove and replace a faulty Schrader valve. I have a couple of these tools, but if you heard my Fun Fact yesterday, you know that I am blessed with messy work bench and tool box. Over the weekend I needed a core removal tool, but could not find one. Instead of running into town to buy another one, I made my own with an old broker nut driver. Why did I have a broken nut driver in my tool box? Because I knew someday it would come in handy, and I was right, at least this time.
