Tow head apparatus for use with different sized aircraft tow pins

An aircraft tow head apparatus for use with aircraft tow pins of different diameters by incorporating multiple side plates that define a tow pin opening sufficiently large to permit adjustment to accommodate the tow pins of different diameters, the tow head apparatus further comprising a locking device to lock the aircraft tow pin into position, the tow head apparatus comprising:

• a pair of side plates each comprising a first side plate and a second side plate that are configured so that when joined together define a space through which a tow pin may be locked into place, the first and second side plates of each pair of side plates having a longitudinal axis and comprising a wall having a thickness sufficiently large to accommodate a plurality of apertures extending through the wall perpendicularly to the longitudinal axis to permit the first and second plate to be mechanically fastened together in one of a plurality of relative positions, where in a first position, the space defined by the first and second plates for the tow pin has a first general nominal diameter and where in a second position, the space defined by the first and second plates for the tow pin has a second general nominal diameter, whereby a user may reposition the first plate relative to the second plate as needed to accommodate tow pins of differing diameters.
