The R. D. Nuttall Co., of Pittsburg. Pa., has developed a line ofsolid gears for electric service, represented by the illustration. The solid type of gear is put onto shaft undera pressure of from 10 to 25 tons, which is sufficient in itself to insurea permanent and tight fit. The design of the solid gear allows aperfect distribution of the material, the result of an exceptionallystrong gear without the disadvantage of great weight thereby being. NUTTALL SOLID GEAR. obtained. The solid gear is rccommcudcd especially for high speedinterurban service where heavy cars and large motors are used,requiring axles of proportionally large diameter, but the that it has received some very flattering reports from themanagement of systems using lighter cars equipped with solid solid gear eliminates a danger of accidents due tj the breakingor loosening of bolts, which almost invariably results in a bent arma-ture shaft and injury to the gear case and other parts that are di-rectly connected. The illustration shows the general design of the Nuttall solidgears but this design may be modified to some extent in order tomeet the requirements as to axle and gear diameters. The companyhas a complete line of patterns and full data on gears for differentmotors, so that orders for solid gears can be filled with exceptionaldispatch. ♦-•-• Plans of the New York, New Haven & HartfordRailroad C
