No. 2. that the wheel runs on a flange instead of on the axle bearings are pivoted in the centre, between thewheels, permitting- them to take a radial position, as thewheels direct. Could the wheels be made absolutely round andexactly to the theoretical diameter, and the tracks per-fectly smooth and laid to an exact circle, the cars wouldthen pass around a curve as easily as on a straighttrack. It is impossible in commercial machinery tofully realize theoretical conditions, but the differencebetween the running gear as furnished by the C. FIG. 5.—COAL AND ASH CAR USED BY CAMDEN STREET RAILWAY Hunt Company, and the ideal ones, is claimed to beslight. Rigid wheel base cars do not run easu-c around acurve because one of a pair of wheels of the same diam-eter secured rigidly to the axle must slide on the rails adistance equal to the difference in the length of the innerand the outer rail. In a car having two pairs of wheels,with the axle boxes rigidly connected to the frames, notonly must this sliding take place, but it is increased bythe unfavorable position in which the axle holds thewheels, as the axles cannot take a radial position, whichis the one most favorable. The C. W. Hunt Companyfurnishes cars of special design for carrying all kinds ofmaterial. Comments and Views of Contemporaries.
