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: The harness device is used to effect head control of a horse and includes a crown assembly connected to a bit in the horse's mouth via a pair of control lines connectable to a strap that is attached either along the belly or the mane of the horse. The crown assembly is effective to fit over the ears of a horse and includes a poll strap extending across the poll area of the horse's head. The strap is detachably connectable to the cinch of a saddle for extending forward along the horse's belly between the front legs of the horse. The pair of control lines extends from the end of the belly strap to the bit via a movable connection with the crown assembly. This controls the upward movement of the head. A pair of control lines attached to a strap extending along the horse's mane controls the downward movement of the head.
