The way they steered the engine was with the chains, it composed of a right and left screw in front of the fire box,as one side drew the chain in, the other side automatically let the chain out! The steering was handled as a normal steering wheel as you see in the picture above the rear wheel, it turned a 90 degree gear that turned the two direction screw, one side fed in or out on the top of the screw and the other fed in or out on the bottom! Both the road roller and regular wheeled traction engines were steered this way. Some manufactures even offered as an option steam powered steering with their engines, like the Avery steam engine, I'll bet they were a hand full on hilly and uneven conditions!
