Abstract: A wheel end assembly for a steerable rear axle of a four wheel steer motor vehicle chassis comprises a constant velocity joint drivingly interconnected with an axle shaft of the steerable rear axle, along a lateral axis defined by the axle shaft, and a wheel assembly for transmitting driving torque therebetween. A yoke has a main body portion with a central, laterally-extending pass-through for the constant velocity joint and is fixedly mounted to the chassis. The yoke has an upper and a lower ball joint arm which laterally extend towards the wheel assembly, where each ball joint arm has a ball joint passage therethrough. A knuckle for transferring steering rotation to the wheel assembly comprises a flat plate body with a central, lateral opening for the constant velocity joint to pass through and splined upper and lower ball joint pockets.

Abstract: An enclosure for a vehicle end opening disposed between two side walls includes a pair of bi-fold door assemblies, each comprising inner and outer panels hingedly connected to one another with the outer edges of the innermost panel in turn hingedly connected to a hinge rod normally disposed adjacent the outer limits of the end opening. Intermediate lock means are included with each pair of door panels for selectively precluding relative displacement therebetween and when actuated allows of folding of each pair of door panels to provide a collapsed juxtaposed relationship following which the folded door assembly may be pivoted about the hinge rod 90.degree. or until parallel to the vehicle side walls.

Abstract: A lock mechanism for a railway car hinge-deck section includes a locking lever pivotally attached to a railway car and having an upper and lower wedge bar alternately engageable with a wedge plate carried by the hinge-deck section when the section is displaced to a raised or lowered position, respectively. Seat means affixed to the car restrict vertical displacement of the deck section and cooperates with mating inclined surfaces on the wedge bars and wedge plate to provide positive, tight retention of the hinge-deck section in either of its locked positions.

Abstract: An enclosure for a vehicle end opening formed between two side walls includes two bi-fold door assemblies each comprising inner and outer panels pivotally connected to one another and with the free edge of the outer panels in turn connected to a fixed pivot point adjacent the side of the end opening wherein, each inner panel may be folded outwardly 180.degree. about its pivoted connecting means and the thus folded assembly subsequently pivoted about its fixed pivot point 270.degree. into parallel relationship with the vehicle side wall. The pivotal connecting means joining each pair of inner and outer panels includes catch means serving to secure the assembly in both the closed position enclosing the vehicle end opening as well as in the stored position parallel with the vehicle side wall.
