When did W D Davis invent the riding saddle?

William D Davis did not invent the saddle. The saddle had been around long before he was ever born. The misconception that he invented the actual saddle came about because he did invent a new type of saddle. His version of the standard issue cavalry saddle had extra springs in the seat and stirrup beds to aid in long journeys on hard trotting horses. However the saddle never really took off and even though it was patented it is not produced anymore.
