  • Patent number: 4460346
    Abstract: An elongate eccentric shaft formed from a cylindrical billet has cylindrical bearing sections at its opposite ends, a cylindrical center section, and cylindrical coupling sections outboard of and eccentric to the center section. The cylindrical sections are of uniform diameter, the bearing and center sections have coincident longitudinal axes, and the longitudinal axes of the coupling sections are coincident with one another and offset from the axes of the other sections. Adjacent each coupling section is an elliptical section having a major axis the length of which is no greater than the diameter of the cylindrical sections and a minor axis the length of which is less than that of the major axis by an amount corresponding to one-half the offset of the aforementioned longitudinal axes.

  • Patent number: 4258629
    Abstract: A radial axle railway truck of the rigid frame type has an improved primary suspension for resiliently supporting the truck frame from the axles while permitting arcuate movements of the ends of the axles required to allow the axles to assume radial positions on curved track and an improved disc brake system arranged to minimize interference with wheel-induced steering movements of the axles. The primary suspension comprises journal bearing structures with fore and aft wings, a yoke supported on the wings by flat elastomeric pads yieldable horizontally to accommodate steering movements of the axles and chevron-shaped elastomeric springs carried on the yokes fore and aft of the respective journal boxes and acting in parallel with metal coil springs carried by the yokes.

  • Patent number: 4237791
    Abstract: A railway truck has a pair of radial axles with journal bearings at their ends and an adaptor mounted on each journal bearing and arranged to support the truck framing for steering movements of the respective axles with respect thereto, rigid links connecting the diagonally opposite axle bearing adaptors via bifurcated yokes to accommodate horizontal turning movements in opposite senses of the respective axles, the adaptors being mounted on the axle bearings to permit limited relative movement of the axle bearings and of the respective axles transversely of the truck with respect to the adaptors, whereby to permit the respective axles, while held in parallelism by the diagonal links, to move transversely of the truck with respect to each other sufficiently to follow transverse offsets in the track rails such as may occur at turnouts and the like without placing excessive strains on the bearing adaptors and linkages.

  • Patent number: 4238006
    Abstract: A radial axle railway truck is provided with a disc brake system compatible with the radial axles comprising a single disc at the center of each axle adapted to be frictionally engaged by opposing shoes of a disc brake mechanism, the disc brake mechanism associated with each axle being supported by a yoke anti-rotatably mounted solely on truck framing supporting adaptors mounted on the axle bearings to take braking torque while accommodating free pivoting movement of the brake mechanism in the horizontal plane in accordance with movements of the axles from their tangent track positions to their curved track radial positions, such that no forces are applied by the disc brake mechanisms to the respective axles in opposition to the steering forces acting on the respective axles.

  • Patent number: 4231296
    Abstract: A railway locomotive has three power trucks with the end trucks each having a bolster resiliently supported on the truck frame and connected to the underframe by cooperating vertical axis pivot-forming means, the middle truck bolster being connected to the underframe by a Watts linkage arranged to directly transmit longitudinal forces from the bolster to the underframe while accommodating substantial excursions of the bolster and middle truck frame transversely of the locomotive underframe for operation of the locomotive on the curved track.

  • Patent number: 4134343
    Abstract: A radial axle railway truck has a pair of wheel and axle assemblies with profiled wheel treads of greater than conventional conicity to steer the assemblies by means of the differential effect of the inner and outer wheel diameters on curved track, the axle bearings are located inboard of the wheels, and the truck frame side members are correspondingly located inboard of the wheels and there supported on the axle bearings such that longitudinally acting resilient restraint means between the axle bearings and the truck frame resist substantial movements of the axles longitudinally of the truck frame while offering only limited resistance as a couple to steering movements of the axles with respect to the truck frame because of the relatively short transverse moment arm between the longitudinally acting resilient means.

  • Patent number: 4088080
    Abstract: A six-wheel railway motor truck for swivelly supporting a locomotive body is connected to the same for the effective transmission thereto of draft and braking forces at a level at or near that of the rail whereby the vertical moment arm through which traction forces might act to tip the truck frame and thereby cause load transference from axle to axle is minimized, with corresponding minimization of such load transference. The truck comprises a rigid frame resiliently supported on the three axles, a body support bolster supported on the sides of the truck frame by upright springs and held against swivelling movements or longitudinal movements with respect to the truck frame while being free for limited vertical and transverse movements with respect to the truck frame.

  • Patent number: 4043272
    Abstract: Railway three-axle, three-motor locomotive trucks are provided with a bolster spring-supported on the truck frame for lateral and vertical movement and having a central opening to accommodate the middle axle motor while minimizing the over-all height of the truck, a plurality of vertically nonyielding body-support bearing elements on the bolster spaced apart transversely and longitudinally of the truck to prevent tipping of the bolster relative to the body, a swivel connection between the body on the bolster, and a draft connection between the bolster and truck frame at a level at least as low as the axles to provide low-level transmission of traction forces between the truck frame and bolster and thereby reduce axle-to-axle load transference and thereby improve adhesion.

  • Patent number: 4041198
    Abstract: Apparatus usable in combination with means for extruding a waterproof plastic sheath on foam coating on the exterior of pipe, for reducing the diameter of the plastic sheath adjacent the pipe section ends to conform to the beveled end surfaces of the foam coating and adjacent protruding marginal portions of the pipe surface and thereby form a water stop excluding moisture from the foam thus enclosed by the plastic sheath.
