Abstract: A multi-wheeled cycle comprising a frame, a main wheel, and at least one auxiliary wheel secured for rotation at one end of the frame forwardly or rearwardly of the main wheel, and a spaced-apart pair of auxiliary wheels secured for rotation at the other end of the frame rearwardly or forwardly of the main wheel. The main wheel is held for rotation to the mid-portion of the frame and includes a conventional crank and pedal assembly for foot rotation of the main wheel while the user is seated atop the cycle. The bottom of the main wheel lies below the plane defined by the bottoms of the auxiliary wheels to facilitate unique maneuvering and operation. The main wheel may also be pivotable about a vertical axis passing through it. All axes of rotation of the wheels are generally horizontal.

Abstract: A manually operated vehicle propelled by motion simulating rowing, the vehicle having a frame with drive wheels and a steering wheel and with a seat mounted between the drive wheels on a rail that rotates around its long axis and is connected to the steering wheel so that rotation of the rail causes steering movements of the steering wheel. The handle assemblies are moved to affect rowing motion and they have adjustable length to provide either greater torque or greater speed from the same rowing motion.

Abstract: A new and unique wheeled vehicle comprising a unicycle-like device. The device employs the same general elements as a unicycle including a single large drive wheel, a pair of pedals, a seat, and a pair of forks to support the seat. Attached to the rear of the device is an additional set of support wheels. The support wheels are attached through a support frame which extends generally rearwardly and downwardly from the center of the drive wheel. The support wheels are attached to one another by an axle, which is in turn attached to the support frame in such a manner that the support wheels pronate and track through turns as the drive wheel is turned to the right or left. Under normal conditions the support wheels remain on the ground at all times. This device provides the rider with additional longitudinal stability without adding a significant increment of lateral stability.

Abstract: A three-wheeled vehicle having a front body member carrying the front wheel and seat, pivotally connected to a rear body member carrying the rear wheels and handlebar. The pivotal connection is designed to pivot the front body member around a pivotal axis that is projected upwardly and rearwardly at a location rearward of the front wheel whereby pivoting produces sideward and rearward tilting of the front wheel and opposite turning of the rear wheels. Steering is achieved by such pivoting of the front body member which in turn is achieved by a sideward swinging of the seat that is positioned between the two pivotal connections. The rear wheels are preferably canted to provide increased stability for the vehicle as it is maneuvered through a turn.

Abstract: This invention relates to a roller bicycle having rollers rotably mounted on the front wheel shaft and a single rear wheel for a common use as a sporting and playing apparatus on which one can ride forward and backward by keeping his balance, thereby improving his agility and developing his physical strength.

Abstract: A bicycle comprises front and rear wheel assemblies which are independently steerable. The rear wheel assembly includes a pedal crank which is mounted on the axle of the rear tire. A rear fork holds the rear axle and includes a shaft which is rotatably coupled to a rear portion of the bicycle frame. A saddle is mounted to the top of the shaft of the rear fork. Turning the saddle and/or the pedal crank laterally rotates the rear wheel assembly independently of the front wheel assembly. The front wheel assembly similarly includes a fork which holds the axle of the front tire. A shaft portion of the fork is rotatably coupled to a front portion of the bicycle frame and is coupled to a handlebar. Turning the handlebar rotates the front wheel assembly independently of the rear wheel assembly.

Abstract: The coaster includes a wheeled foot platform, the steerable wheel of which is rotatable on a swiveled axle for effecting a steering action. The swiveled axle extends through aligned horizontal slots in vertical axle guides where are spherically curved. Each axle guide has at least one axially extending flange on which rides a bearing element or roller assembled on the axle. The roller and another bearing element assembled on the axle have complementary curved surfaces in sliding bearing engagement with opposite curved sides of each guide for axially constrained swiveled or turning movement of the axle. Steering of the coaster is obtained by a foot steerable plate mounted for pivotal movement on the foot platform. A mechanical linkage is connected at one end by a sliding pivot to the plate and at its other end to one or both ends of the swiveled axle.

Abstract: Three-wheel motorcycle with cambering main frame supporting a front steering column and front wheel. The cambering frame is pivotally mounted on a centralized non-cambering rear support including the engine that carries the rear suspension and laterally spaced drive wheels. Operator footrests are mounted on rear support and automatically tilt with the cambering frame to improve operator balance of the vehicle.

Abstract: An amusement tricycle wherein the operator is transported in an inclining position on a hammock cradle. the cradle is carried by a front wheel which does not pivot relative to the cradle. The cradle and wheel rotate about a downwardly sloping axis to turn. The cradle is supported to the rear by a two wheel buggy. The cradle is mounted on the buggy by a pivot. The pivot rotates about the axis. The buggy in turn, is stabilized by pivotal attachment to the cradle.

Abstract: A velocipede having a single driving wheel which is powered by rotating pedals that rotate a sprocket that is connected to the driving wheels by a chain. A roller assembly comprises small diameter rollers having a roller axis that is disposed lower than and in front of the pedal axis. The rollers are connected to the velocipede frame by a bearing member so that the rollers can be articulated allowing the rider to lean on the velocipede thereby controlling the direction of movement.

Abstract: A wheelchair having at least one pivotal wheel which is steerable in a mar which does not interfere with the manual driving of the wheelchair, by providing a pair of levers linked to the pivotal wheel or wheels and actuable by movement of the upper body of a user of the chair, each lever being movable to steer the wheelchair in one respective direction only.

Abstract: An improved recumbent bicycle having a carriage unit comprising an improved seat assembly and handle bars. The carriage unit is adjustably mounted on the frame of the bicycle so that it is movable toward and away from the foot pedals in order to accommodate different sized riders.

Abstract: A vehicle powered to move about on a front drive wheel and rearward supports, preferably a pair of wheels. The rear wheels are mounted to the frame by a steering control mechanism that facilitates pivotal steering movement of the rear wheels about two axes - a steering axis and a steering control axis. The steering control axis is coaxial with the rear wheels and is perpendicular to the steering axis. The angle of the steering axis may be varied about the steering control axis. Steering is accomplished by the rider shifting his weight from one side of the vehicle to the other. He may shift the steering axis to a position substantially parallel with the ground surface so the frame may be tilted like a bicycle in wide, sweeping high speed curves. The rear wheels then track behind the front wheels as the frame tilts about the steering axis. If the rider shifts the steering axis to a position nearly perpendicular to the ground, he may negotiate short radius, low speed turns.

Abstract: Steerable movement over unimproved, grassy or snowy ground is provided by a chassis carrying front and back elliptical wheels, wider than they are high, the front wheel being pivotable in a horizontal plane.
