Patent for a new and improved tire-tightener. This design has "parts [that] are the width of a felly and a fraction less their depth, and bearing solid against their ends are held in place by flanges on each end. As the screw is turned in it forces the parts against the ends of felly, forcing the fellies against the tire, and is prevented from coming in contact with the tire by a rubber fender, or of other substance placed under tire-tightener. Fender is held in place by flanges at each side on bottom of tire-tightener; is also provided with a sliding joint on sides to cover the opening made by expansion" (lines 14-26).
