GRAVITY COUPLER CENTERING DEVICE STEEL PASSENGER CAR PAINTING* A device for centering couplers which does not require theaid of springs is shown in the accompanying illustrations. Itincludes a cast steel carry iron of much the same form that isnow generally used in steel freight cars, the essential differencelieing that there are two concave recesses cored in the Secfhn B-B. -^ Powers Gravity Centering Device for Couplers. Two cast steel rollers connected by a bar, rest in these re-cesses and on them rests the carriage that carries the shank ofthe coupler. It is evident that when the coupler is off center oneither side it will be lifted up and its weight will tend to forcethe rollers to the bottom of their cavities and thus return the
