Abstract: A cable reeler having two pairs of sprockets rotatable about spaced parallel axes. Endless roller chains entrained around the sprockets and a motor driving one of the sprockets to rotate the other sprockets to move the endless roller chains. Cable support members carried by the roller chains having elongated arms to retain the cable on the reeler.

Abstract: A steering mechanism for an articulated vehicle having a first section and a second section connected by an articulation joint. The steering mechanism includes an annular member connected to the first section and a moveable steering plate slideably mounted on the second section. The annular plate and the steering plate are connected by chains and a pair of opposed piston and cylinder devices are mounted on the second section and connected to the steering plate to move the steering plate and the chains to adjust the position of the annular plate to rotate the first section of the vehicle relative to the second section of the vehicle about the articulation joint between the sections.

Abstract: An articulation joint for pivotally connecting adjacent sections of a vehicle. The joint includes a first slewing ring and a second slewing ring. Each slewing ring has an outer member and an inner member with a bearing race located between the outer and inner members to provide relative rotation of the members. The outer member of each slewing ring is constructed for connection to one section of a vehicle and the inner member of each slewing ring is constructed for connection to the other section of the vehicle.
