Samuel Colt’s revolver was revolutionary because the cylinder rotated mechanically when the hammer was cocked as it was pulled to the rear. This experimental Third Model Dragoon Revolver has an extremely unorthodox and complex revolving mechanism. When the hammer is engaged, a curved rectangular plate beneath the cylinder is pushed forward by an arm attached to the hammer, part of which is visibly protruding from the rear of the frame. Grooves on the sliding plate ultimately engage pins on the cylinder, causing it to rotate. Although this particular design was deemed impractical and never patented, it illustrates an active research and development program at Colt’s Patent Fire Arms Manufacturing Company. Most of the patents issued during Colt’s career were to himself and his superintendent and chief associate, Elisha King Root.
