The fifth wheel that never caught on.
So before I get into that I always wondered where the fifth wheel we all know got its name.
"The term 'fifth wheel' comes from a similar coupling used on four-wheel horse-drawn carriages and wagons. The device allowed the front axle assembly to pivot in the horizontal plane, to facilitate turning. Basically a wheel was placed on the rear frame section of the truck, which back then only had four wheels, this wheel that was placed on the frame was the "fifth wheel" hence the name. The trailer needed to be raised so that the trailer's pin would be able to drop into the central hole of the fifth wheel. Today's fifth wheels allow the trailers to slide into the fifth wheel and lock into it, and are a very reliable unit when maintained and serviced properly. The invention of the fifth wheel is often credited to U.S. inventor Charles H. Martin of the Martin Rocking Fifth Wheel Co. who invented the device in 1911."

Now a rant, kids these days aren't learning to drive cause some cars practically park themselves.
Anyways, the other fifth wheel.......
