Atthe fourth blow the horn of the coupler struck the end sill. A twin spring arrangement is illustrated, but the tandem,Single spring, or a friction gear may be applied gand any of these forms may be readily applied to old equip- ni. Other interesting features are the initial compression of the springs by driving in the keys with the taper ends andthe tact that the gear will do its work even if a spring isbroken and lost in transit.

LOCOMOTIVE TESTING PLANT AT ST. LOUIS. This gear was designed to provide the necessary strengthand capacity to resist shocks of service in a construction whichis easily repaired. Many gears which are satisfactory in everyother respects are difficult to repair, and few are so made asto he taken down and replaced by one man. The Farlowdraft gear combines a coupler, with the elongated slot; frontand rear followers, also slotted; three keys, passing throughthe slots in the drawbar and followers and also passingthrough the draft sills or draft castings and two slotted draw-bar links, one at each side of the coupler. The arrangement is illustrated in the accompanying engrav-ing. In addition to the keys for taking huffing shocks, therear face of the rear follower is broadened to bear against anoak block which is bolted between the draft timbers and bea
