  • Patent number: 7011163
    Abstract: The present invention teaches a horseshoe including a plurality of calks for enhancing traction. The calks are located on sloped interior side wall portions of the horseshoe. Each calk includes a small rounded leading end and a rearwardly and outwardly tapered surface for permitting the horseshoe to slide forwards during the braking or planting phase of the gait cycle. Further, each calk includes a grab surface on the trailing end for enhancing traction during the propulsive or thrust phase of the gait cycle. The horseshoe of the present invention can reduce the magnitude of the shock loads experienced by a horse during the hoof planting phase by sliding slightly on the hoof lands, and improve traction with the rear grab surface during the propulsive phase of the gait cycle.

  • Patent number: 5230384
    Abstract: The horseshoe assembly of the present invention comprises a U-shaped pad member having one or more glide clips attached thereto around its outer circumference. Each of the glide clips has a glide surface protruding a short distance below the bottom surface of the pad member. The coefficient of friction of the glide members is less than that of the pad member. At least one elongated stud is fitted within a stud receiving hole in the bottom surface of the pad member and includes a lower stud end protruding below the bottom surface of the pad member.

  • Patent number: 5165481
    Abstract: The present invention is an improved horseshoe intended for use in competitive situations. It is specifically designed to conform to the anatomical structure of the horse's hoof, and to have little effect on the performance of the horse, either due to wear of the shoe or growth of the horse. It includes:a toe sloping upwardly at the laterally extended intersection of the lower surface of the shoe and a plane, containing the axis of articulation of the hoof and extending downwardly and forwardly to the intersection;a wear-resistant area, located at the intersection, by means of a wear-resistant insert or material applied thereto;a perpendicular web at the rear of the toe portion for added support;a wedge shape to the mid-sections of the arms to improve withdrawal from turf, etc.;rounded outer edges of the heel ends of the arms, widened arms, and a relieved inner surface of the toe portion, to give greater cushioning during strenuous activities, such as running, jumping, and the like.

  • Patent number: 5158143
    Abstract: A lightweight horseshoe particularly suitable for competitive events requiring high maneuverability, the horseshoe including a body having a plurality of sharp ribs extending from the shoe ground engaging face. Four ribs are employed across the shoe body width, the front rib constituting a deeper penetrating grab. The ribs are configured to be self-cleaning, and the shoe includes homogeneous reinforcing bars to resist outward shoe deformation under lateral stress. The reinforcing bars intersect the shoe outer and inner sides, and clearance slots formed in the shoe outer side adjacent the reinforcing bars facilitates the self-cleaning of the shoe adjacent the bars.

  • Patent number: 5048614
    Abstract: A composite horseshoe made of a resilient urethane material and containing therein four separate, spaced apart metal inserts. The first metal insert forms a core in the shape of a horseshoe and lies entirely within the resilient horseshoe. The second and third metal inserts are relatively short elongated plates which lie above the two ends of the first metal insert, with the upper face of each plate lying flush with the surface of the resilient horseshoe. The fourth metal insert is a curved elongated plate called the toe grab which lies along the front of the resilient horseshoe and projects outwardly from the resilient horseshoe.

  • Patent number: 5004052
    Abstract: The horseshoe includes a traction surface having a toe portion defining a pair of parallel calks and a pair of side portions defining a plurality of inner and outer calks. The calks have a truncated wedge shape designed to increase traction and minimize the build-up of dirt and mud. The horseshoe is also provided with an outer coating of non-stick material which prevents mud and dirt from adhering to the horseshoe to maintain a "clean" traction surface.
