To prevent chips, falling between theface plates, from getting into the working parts of the machine,a sheet-iron telescoping cover is provided extending from oneface plate to the other. A calipering attachment is supplied (not shown in the illus-tration), consisting of a cross-bar extending above and acrossthe face plates and set parallel with the center line of the ma-chine. With this is furnished a suitable measuring device fordetermining the relative diameter of the two wheels. A four-step cone is used with the belt drive, or the machine can be arranged for motor drive—preferably by a motor of the variablespeed 2036 O*- NILES STEEL-TIRED CAR-WHEEL LATHE. To turn wheels on axles having inside journals the ordinarycenters are used and the wheels are gripped by the drivers inthe usual manner. The face plates are mounted on spindles ofextra large diameter. The right-hand head is movable on thebed by rack and pinion operated by lever. The tool rests have swiveling bases adjustable in and out onthe carriages and are provided with power longitudinal feeddriven by ratchets with positive connections, which are operatedfrom the rocker shaft at the front. The carriages have adjust-ment parallel to the length of the bed for varying gauges. Thetool posts are fitted with an improved type of tool clamp, en-abling the tools to be set with the greatest facility and in the For railroad work the machine is provided with four sets ofaxle bushings for 3%, 4J4, 5 and 55/2 in. standard M.
