Fig. 13—Class 1-C-1 locomotive with two jackshafts,and two motors mounted in the ends of the body. Thedrawing shows the locomotive of this class built by theMaffei Company, Munich, and equipped by the Siemens-Schuckert Company for the Wiesental line of the BadenState Railways. Ten locomotives were ordered, but the oneshown was built first in order that the design might be. Figs. 14 to 23—Locomotive Drives—Diagrams of Arrangements locomotive has a leading and a trailing four-wheel truck topermit high-speed service. Fig. 10—Gearless locomotive with motors built on hollowaxles concentric with the driving axles. The drawing showsa New York,. New Haven & Hartford single-phase of this class. The hollow axle, or quill, on whichthe motor is built is bored with sufficient internal clearanceto permit the usual vertical movement of the axle boxes intheir guides without actual contact between the quill and theaxle. The quill carries at each end a spider which forms aflexible coupling with the driving wheel. The locomotiveis arranged as a double-truck machine, each truck havingtwo driving axles and a single-axle sub-truck at itsouter end.
