Before each axle is run out on the carrier, it is inspected and marked to indicate the respective point at which it is to be dumped from its cradle. In the process of dismounting wheels from their axles a good many of the latter are simply swung around on the jib crane over the press and deposited behind the axle lathes, for refitting at once for service. A great many more, however, are passed immediately out of the shop and onto the storage piles referred to. The carrier itself consists of a four-wheeled steel truck carrying above its platform a pair of arc-shaped cradles, which normally are in the position shown in Fig. 200 for holding the axle. Under Fig. 200.--Axle carrier in wheel shop. neath the platform there is a set of wedge-shaped members that are adapted to slide longitudinally to tilt the cradles in either direction for the purpose of discharging the axle either to the right-hand or the left-hand side of the carrier. This wedgeshaped controlling device, when in the position indicated in Fig. 200, holds both cradle members in a horizontal position so that the axle rests securely in place until the cradles are automatically tilted after the carrier has been run out along its track to a predetermined point for the discharging of the axle. OPERATION OF CARRIER The truck, or carrier, is drawn along its track by a wire cable passing over drums beneath the ends of the track. The operation of the driving drum, and hence of the carrier itself, is effected by a long-stroke cylinder and piston with suitable gear and cable connections for giving the desired length of travel and the requisite rate of speed for the carrier. Between the tracks upon which the carrier is operated...
