Abstract: Fasteners are configured to anchor a horseshoe to a hoof. The fasteners are used in conjunction with wrapping, banding and/or casting material to secure a horseshoe to a hoof. Methods of anchoring a horseshoe to a hoof employ fasteners and wrapping, banding and/or casting material.
Abstract: The present invention provides an improved horseshoe, which comprises a hoof engagement surface that is provided with an unevenness and makes contact with the hoof in such a manner that the shoe will fit more closely to and immovably against the bottom of the hoof. The unevenness provides an anti-slip interference with fibrous material of the hoof to lessen relative movement between the horseshoe and the hoof, both during assembly thereto by a farrier and during galloping of the horse, desirably inhibiting shearing stresses being placed on the securement nails. The anti-slip interference is provided by an array of bumps or hemispherical shaped domes that project upwardly from the hoof-engaging surface to displace fibrous hoof material and complete an interlocking engagement therewith in an amount sufficient to inhibit relative movement but not create discomfort to the horse.

Abstract: A process for gluing a horseshoe having a rim extending upward around the sidewall of the hoof. In an earlier process, both the hoof and the part to be attached, if any, were preheated to about 275.degree. F. and then bonded with a hard paste-type urethane adhesive. Principal new features are grooving of the sidewall to increase bond strength and lowering the sidewall preheat temperature to 220.degree. F. in order to eliminate the discomfort sometimes experienced at 275.degree. F. by horses with thin sidewalls.

Abstract: A two part plastics material horseshoe has a relatively flexible plastics strip part of generally L-shaped cross-section, shaped so as to be suitable for adhering to the side wall of a hoof, and a relatively inflexible plastics shoe-part adapted for bonding to the strip-part once the latter has been adhered to the hoof. The two parts are pre-united in the toe region, to set the relative dispostion thereof prior to adhering the strip part to the hoof. Attachment of the strip-part to the hoof is enhanced by providing a liner having a rough texture within the strip-part, and the shoe-part may be affixed to the strip-part by a heat-welding technique.
Abstract: A method of and apparatus for shoeing horses using a plastics material horse shoe. A flexible L-shaped strip, preferably preformed from plastics to fit a hoof, is adhered to the front and side walls of the hoof as well as to the peripheral region of the sole. Then the plastics shoe is adhered to the underside of the strip. The provision of a separate strip allows a satisfactory indirect bond of the shoe to the hoof by using anaerobic, fast-setting adhesives. The strip should be relatively resilient, whereas the shoe should be relatively hard and rigid.
Abstract: A hoof covering for horses comprises a horseshoe-shaped plastic body which has a generally acute-angled cross section so as to form a lower side with a flat upper surface and an upwardly extending side in the form of a conical side wall.
