ABSTRACT:
Hitch for securing a racing sulky to a harness or saddle of a horse. The hitch has an elongated, generally cylindrical body which includes a frustoconical tapered front portion, a generally cylindrical mid-portion and a cylindrical rear portion of slightly smaller diameter than that of the mid-portion so as to form a shoulder. The rear portion is adapted to be inserted into the open end of a tubular shaft, such as a shaft of a racing sulky. When so inserted, the hitch may be permanently secured to the shaft. The mid-portion of the hitch includes cylindrical front and rear end members which adjoin the front portion and the rear portion respectively of the hitch. The mid-portion of the hitch has one or more cutouts which define a longitudinally extending rigid strut and (when there is more than one such cutout) one or more transverse spacer discs, which are spaced from the end members and from each other. A rigid rod extends through the rear portion and the mid-portion of the hitch. The strut and the rigid rod (and the spacer discs when present) together define one or more slotted openings for receiving a strap or the like which is associated with a harness or saddle. Preferably the entire hitch except for the rigid rod is formed from a single piece of material; the rigid rod may be formed from a second piece of material and joined to the remaining structure. Either metal (such as steel or aluminum) or rigid plastic can be used for forming the hitch.
