Abstract
The steering system includes a rotatable steering control member located remotely from a steerable dirigible wheel unit, a drive sprocket mounted for common rotation with the steering control member, a short length of roller or sprocket chain trained about the drive sprocket, a driven sprocket mounted for common rotation with the dirigible wheel unit, a short length of roller or sprocket chain trained about the driven sprocket, and flexible members, such as wire cables, interconnecting the chains so that the driven sprocket is rotated in response to rotation of the drive sprocket. Two sets of coaxially aligned pairs of pulley are located between the drive and driven sprockets and the cables are trained over the same sides of the pulleys in each set and thereby are guided through a circuitous route between the sprockets. One set of pulleys is adjustably mounted relative to the cables for adjusting the tension applied on the cables to remove slack therefrom.
