Abstract: An apparatus includes rails for supporting sides of a circumferential peripheral edge of a carrier. A movable ram engages a rearward portion of the carrier. A movable restrainer restrains movement of the ram. A wheel engages a forward portion of the carrier. A controller is operable to control the movable restrainer to restrain movement of the ram with the carrier and at least one metal object disposed adjacent an induction heating device, the wheel to rotate the carrier and the metal object, the induction heating device to induction heat the rotating metal object, and the movable restrainer to disengage the ram so that the wheel pivots away to allow passage of the carrier and the heated metal object into a quench bath. A plurality of metal objects may be arranged in a circular array in the carrier about a diameter generally equal to the diameter of an induction coil.
Abstract: A train axle assembly includes a train axle, a ring assembly coaxially mounted on the train axle and a structure operatively engaged by the ring assembly and mounted on the train axle. The ring assembly has an outer diameter and a main section adjacent the outer diameter. The ring assembly includes a projection extending axially from the main section which is located at a diameter less than the outer diameter of the ring assembly. The projection has a portion of a diameter contacting the train axle so that the ring assembly is affixed to the train axle to provide resistance to relative rotation and axial movement between the ring assembly and the train axial.
