Abstract: An anti-choke attachment for a horse for preventing internal blockage of the horse's nasopharynx or other blockage of the horse's breathing when the horse is running or vigorously exercising. The attachment temporarily locks the horse's head against tilting downwardly or swinging sidewise. The attachment comprises a rigid plate having a lower part shaped to fit against a horse's neck and an upper part shaped to fit beneath the rear portion of the horse's jaw. An elongated, relatively thick, resilient pad arranged on the upper part is arranged to fit closely within the intermandibulary space region along the rear of the horse's head so as to prevent downward tilting and sidewise swinging of the head relative to the neck which both prevents partial blockage of the nasopharynx and helps maintain driver control of the horse.

Abstract: A new nostril support device for a horse comprises a shaped body for insertion into the nostril and an integral clip that retains the body in position by pressing on the outside of the nostril. The shape of the body is generally convex toward the clip and concave away from the clip. In a direction substantially parallel to the clip the body is substantially straight at the bottom of the concavity. Overall the body tapers to a substantially parabolic edge to ease insertion into a nostril.

Abstract: The tree of a harness saddle band is formed of an elongated, narrow, thin, strip of resilient plastic material bent into an inverted U-shape having a central bight portion and integral depending leg portions. The bight portion is stiffened to resist bending or flexing of the bight portion. The depending leg portions are resiliently flexible relative to the bight portion for independently bending laterally towards an away from each other and for independently bending longitudinally forwardly and rearwardly of the horse. The junctions between the leg portions and the bight portion are provided with raised ribs which are decreasingly tapered in the direction from the bight portion towards the free ends of the leg portions.

Abstract: A harness racing quick hitch comprises a pair of swivel joints in the hitch. The pair of swivel joints permit the harness saddle to rotate about a vertical axis relative to the sulky arm. This rotation provides a degree of freedom not otherwise present in the connection of the sulky arm to the harness saddle. Thus, the swivel joints in the quick hitch separate further the flexing movement of the horse flanks from the rigidity of the sulky arms. Modifications to the swivel joints provide further freedom of movement to the horse and therefore comprise alternative embodiments of the new swivel joint quick hitch.

Abstract: A device for correcting the gait of a bad gaited horse comprises soft flexible tubing with a strap routed therethrough. The tubing is placed in the armpits between the horse's body and the tops of the forelegs causing the horse to turn the knees of its forelegs slightly outwardly and thereby reduce a knock kneed or toes out condition. The strap has loops with buckles at the ends to adjustably connect with the shafts of a sulky. Shock cords provide tension between the loops and strap at the ends. Safety straps also connect the strap in the tubing with the loops and buckles at the ends. A chest strap with a buckle connects the strap and tubing across the chest of the horse. The device is placed around the neck of the horse and is buckled across the chest. The ends of the device are brought under the body between the front legs and snugged up by fastening the ends to the sulky shafts. With proper adjustment the tubing is positioned in the horse's armpits. The method of installing the device is also disclosed.
