The standard 10,000-gal. tender which is used with theheavy Mikado type is identical with that in use with the lightMikados, and will also be used on several other of the stand-ard tvpes. The design of this tender was briefly outlinedin the description of the light ^likado type locomotive. It iscarried on four-wheel trucks with 6-in. by 11-in. journals,and among the specialties with which these trucks are fittedit may be of interest to note that the brakebeams are carriedon the Creco three-point support and that Woods side bear-ings are used. The main rods are of heavy channel section and difter in. Main Rod for the Governments Standard Heavy Mikado Locomotive ■^2i forward driving wheel pedestals and to the rear pedestalsof the second and third pairs of drivers; and deck bracesapplied to the top rails between the first and second and thethiid and fourth pairs of drivers. The forward verticalbrace includes a diagonal extension which is bolted to the but ver_\- few dimensions from those of the standard lightMikado. The stub ends are of the strap t}pe with removablecrank jjin brasses. Tlie specialties with which these locomotives are fitted in-clude Everlasting blowoff valves, Ashcroft gages, the Detroit 494 RAILWAY MECHANICAL ENGINEER Vol, 92, No. 9 six-feed lubricator. Hancock No. 11 non-liftiiiL; injectors,Barco flexible connections between the engine and tender, theBarco blower fitting, Sargent (juick-acting blower valves, andthe Radial buffer and Init safety bar l)etween the engine andlender.
