Abstract: A dirigible vehicle which is supported upon at least three ground engaging wheels located about the lower periphery of the device. Two of the three wheels are steerable while the third is fixed in position with its axis perpendicular to a line interconnecting the two steerable wheels. By manipulation of the steerable wheels, the vehicle may be adapted for movement along a linear path or may be made to spin about its own axis. Intermediate positioning of the steerable wheels will cause the vehicle to sweep in large circular arcs. The device may be self-propelled by a foot pedal assembly or by a small motor, with either a single steering wheel or dual independent steering controls. The unique steering capabilities of the vehicle make it ideally suited for recreational purposes or wherever extreme maneuverability is required.

Abstract: In a draft implement having an input power driveline and a tongue adapted to be articulately connected to a tractor, an arm is pivotally mounted on the tongue and supports the driveline rearwardly of a forward telescoping assembly of the driveline which includes forward and rear universal joints. Centering tension springs extending along the tongue and interconnecting the pivotal arm and the tongue maintain the arm in a centered position in which the rear universal joint is positioned the same distance rearwardly of the tractor/implement articulate connection point as that at which the forward universal joint is positioned forwardly of the connection point. The springs will yield to allow the arm to pivot laterally to either side of the tongue to accommodate bottoming out of the telescoping assembly during sharp turns of the tractor relative to the implement. Once the tractor is re-articulated out of the sharp turn relative to the implement, the springs return the arm to its centered position.

Abstract: An improved acceleration control system is utilized to prevent overspeeding or spinning of engine driven vehicle wheels. The acceleration control system includes a first sensor for detecting variations in the rate of rotation of engine driven wheels and a second sensor for detecting variations in the rate of rotation of nondriven wheels. The two rates of rotation are compared and if the rate of rotation of the driven wheels exceeds the rate of rotation of the nondriven wheels by more than a predetermined amount, a mechanical-hydraulic throttle motion divertor assembly is activated to reduce engine operating speed. The divertor assembly includes a pair of pistons which cooperate with a body of liquid to transmit motion from an accelerator pedal to a throttle linkage. During normal operation of the vehicle, the volume of the body of liquid remains substantially constant and the body of liquid is effective to transmit hydrostatic pressure forces between the two pistons.
