Abstract:

A horseshoe for attaching to a horse's hoof using an adhesive, such as glue. In one example, the horseshoe includes an elastomeric body containing a toe portion, a first branch, a second branch, and a heel portion. A first slot extends laterally through the heel portion of the first branch. A second slot extends laterally through the heel portion of the second branch, and substantially aligns with the first slot. A resilient plate aligns with, and extends between the first and second slots. The plate is substantially perpendicular to at least a portion of the first and second branches. The aforementioned horseshoe may be attached directly to a bottom of a horse's hoof using adhesive bonding. Alternatively, the aforementioned horseshoe may also include a fabric cuff, which may be glued to a horse's hoof by applying adhesive between the cuff and the outside-vertical section of the hoof wall.

Abstract:

A protective covering for a horse's hoof is provided which comprises a horseshoe having convex and concave edges and a polymeric fiber fabric embedded in a polymeric resin bonded to the horseshoe. The fabric extends beyond the convex edge of the horseshoe. When the shoe is fitted to the horse's hoof, the fabric extends up over the outside of the hoof. The protective covering is secured to the hoof using an acrylic structural adhesive both between the hoof and the shoe and between the polymeric fiber fabric and the outside of the hoof. The polymeric fiber fabric is preferably a polyolefin, and particularly preferred is woven polyethylene. The polymeric resin is preferably polyurethane.

Abstract:

A protective covering for a horse's hoof which comprises a horseshoe having convex and concave edges and a skirt embedded in a polymeric resin bonded to the horseshoe and extending beyond the convex edge of the horseshoe. The skirt may be made from any suitable flexible sheet material including a polymeric fiber fabric, a molded thermoplastic sheet material, or a laminate of molded thermoplastic sheet material and polymeric fiber fabric. When the shoe is fitted to the horse's hoof, the skirt extends up over the outside of the hoof. The protective covering is secured to the hoof using an acrylic structural adhesive both between the hoof and the shoe and between the skirt and the outside of the hoof. The skirt is preferably a thermoplastic acrylonitrile-butadiene-styrene. The polymeric resin is preferably polyurethane.
