  • Patent number: 10875552
    Abstract: A railcar bogie includes a wheelset, a bearing rotatably supporting the wheelset, an axle box, and an obstacle deflector. The wheelset includes: an axle and a pair of wheels provided at both car width direction sides of the axle. The axle box includes: an upper axle box element covering the bearing from above; and a lower axle box element fixed to the upper axle box element and covering the bearing from below. The obstacle deflector includes an obstacle deflecting portion and a coupling portion. The obstacle deflecting portion is arranged at one side of the wheel in a car longitudinal direction and, when viewed from the one side in the car longitudinal direction, overlaps the wheel.

  • Patent number: 10766542
    Abstract: A fender for a lawn mower having tire and wheel assemblies that are mounted to a yoke of a swivel caster assembly, whereby the yoke pivots through 360 degrees of rotation, includes an arcuate fender body. The fender body is attached to the yoke by a bracket so that it is rotatably carried by the rotating yoke. As such, the fender body is maintained at an optimal position relative to the mower tire, and thereby provides desirable deflection of lawn clippings and other debris from the various operational components provided upon the mower deck. This prevents the premature wear of such operational components, thereby decreasing down time and reducing maintenance costs of the mower.
