ABSTRACT:
An improved model railroad coupler incorporates a coupler shank, having a joining element at one end thereof and a coupler head at the other end thereof. A coupler-knuckle receiver is located within the coupler head and receives a coupler knuckle. The knuckle is provided with limited, rotational movement within the coupler head, through a predefined arc. The coupler head has a first knuckle stop located thereon which limits rotational movement of the coupler knuckle relative to the coupler head in a first direction of rotation. A second knuckle stop is located on one side of the coupler head adjacent to the shank. A knuckle limiter is located on the coupler knuckle. The second knuckle stop and the knuckle limiter are constructed and arranged to abut one another when the coupler knuckle is shifted to an open position, thereby stopping rotation of the coupler knuckle relative to the coupler head. A spring is carried on the second knuckle stop and the knuckle limiter, extends therebetween, and is operable to urge the coupler knuckle to a closed position wherein the coupler knuckle abuts the first knuckle stop.
