ABSTRACT:
A towing head is provided including three primary members. The first member is stationary and includes a channel which receives the tow pin or towing fitting of an aircraft. The second member pivotally attaches to the first member and itself includes a channel which communicates with the channel of the first member. The third member rotatably attaches to the second member and includes a handle for which to place the towing head in either a locked, partially locked, or unlocked position. In the unlocked position, the second member is moved away from interfering with the channel of the first member so that the tow pin or fitting may be freely inserted or removed from within the channel of the first member. In the locked position, the second member is moved to a position so that it interferes with the channel of the first member and prevents the tow pin from being removed from the towing head. The second member may be moved to a partially locked position prior to engaging the tow pin with the towing head which enables an operator to release the towing head once the tow pin engages the towing head because the towing head, while in the partially locked position, can secure the tow pin without locking.
