This illustration dates to the 1870s and shows Stephenson's link motion. At the time, locomotives were fitted with an ingenious apparatus for reversing the engines that was first adopted by Englishman George Stephenson. Here you see thelink motion, where A, B are two eccentrics oppositely placed on the driving shaft and their rods joined to the ends of the curved bar or link, C D. A slit extends nearly th whole length of this bar and in it works stud E, forming part of the lever, F, g movable about the fixed joint, G, and having its extremity, F, jointed to the rod H that moves like a slide va
This illustration dates to the 1870s and shows Stephenson's link motion. At the time, locomotives were fitted with an ingenious apparatus for reversing the engines that was first adopted by Englishman George Stephenson. Here you see thelink motion, where A, B are two eccentrics oppositely placed on the driving shaft and their rods joined to the ends of the curved bar or link, C D. A slit extends nearly th whole length of this bar and in it works stud E, forming part of the lever, F, g movable about the fixed joint, G, and having its extremity, F, jointed to the rod H that moves like a slide valve. The weight of the link and the eccentric rods is counterpoised with a weight, K, attached to the lever I K, which turns on the fixed center, L. This lever forms one piece with another lever, L M with which it may be turned by pulling the handle of O P, connected with it through the system of jointed rods. By keeping the link nearer or farther from its central position, the throw of the slide-valve will be shorter or longer, and the steam will be shut off from entering the cylinder when a smaller or larger portion of the stroke has been performed.
