Abstract
A variable speed vehicle has a satellite vehicle attached thereto by a connecting member. The variable speed vehicle includes a spring activated motor and a power train which is capable of receiving power from the motor and driving the vehicle at at least two velocities. The connecting member is fixedly attached to the satellite vehicle and movable with respect to the primary vehicle. When the satellite vehicle is moved away from the primary vehicle, the connecting member activates the spring motor, and when so activated, the spring motor returns the satellite vehicle towards the primary vehicle by acting on the connecting member. A velocity governing device is operatively associated with the power train and is responsive to the position of the satellite vehicle with respect to the primary vehicle. When the satellite vehicle has been moved away from the primary vehicle and is being returned thereto by the connecting member, the velocity governing device senses its position, and in response thereto the power train moves the primary vehicle at a first velocity, and when the satellite vehicle has been returned to the primary vehicle by the connecting member, the governing device sense…
