  • Patent number: 5740866
    Abstract: A horseshoe having holes for horseshoe nails extending therethrough and including a resilient material. Washers are embedded in the resilient material and horseshoe nails extend through the washers and the holes when the horseshoe is fastened to a horse's hoof. A portion of the horseshoe adapted to bear on the hoof comprises a plate against which the resilient material adheres. The washers abut the plate and are horizontally movable relative thereto, and the holes in the plate have a larger cross section than the nail, such that the nail is capable of moving horizontally together with the washers during loading of the horse's hoof.
