The street railway review . e \>nU-pieces between the armatures being carried by heavy steel tran-soms bolted to the side frame and forming part of the magneticcircuit as well as cross braces for the truck.

[Vol. XIV. No. ii. frame and siipcrstriicture from a system of half elliptic springs andequalized levers of forged sleel. the whole being so arranged as tocross-equalize the load and to furnish three points of support. This constrmtion besides being strong and simple in design greatlyfacilitates rei)airs and renewals as an armature with its wheels andaxle niay be removed by lowering the complete element without dis-turbing the fields or any other part of the locomotive and a newclement inserted in its place. All parts arc also especially accessiblefor inspection and clcnninj;. ELECTRIC LOCOMOTIVE CONTROLLER. The brush holders are mounted on insulated supports attached tothe spring .saddle over the axle journal, thus maintaining a fixedposition of the brush holder in relation to the commutator. Thesebrush holders are made adjustable so as to allow for wear of thecommutator and journal bearings. The dead weight on the axle is not materially greater than iscustomary with steam locomotives and in addition there is no un-balanced weight to produce vibration with attendant injuries to trackand road bed construction. The superstructure consists of a central cab for the operator con-taining master controllers, engineers valves, and switches and valvesrequired for operating sanding, whistling, and bell ringing devices.
