This bearing 172 STREET RAILWAY JOURNAL. [Vol. XXV. No. 4. consists of two races, one of which is fastened to the armatureshaft and the other to the bearing housing. Between the ballsare placed spring separators, which are packed with mineralwool. This mineral wool takes up the lubricant and feeds it CARS FOR THE INDIANAPOLIS & CINCINNATI TRACTIONCOMPANYS SINGLE-PHASE LINE. FIG. 2.—INTER-POLE MOTOR DRIVING 16-IN.

The only attention required for thebearing is to have the lubricant renewed once about every sixmonths. This bearing is shown in position on the end of thearmature shaft in Fig. 1. The framing and dimensions of the ten cars which the Car Company is completing for the new single-phasealternating-current railway of the Indianapolis & CincinnatiTraction Company are shown in the accompanying cars are among the heaviest ever built for interurbanservice, the weight complete, including motors and electricalequipment, being 96,760 lbs. Part of this weight is due to avery heavy construction of the car body and trucks, and part tothe fact that the car is equipped with alternating-current mo-tors, which are somewhat heavier than d. c. motors of the samecapacity, and which also require transforming appara
