SUMMARY OF THE INVENTION
The primary object of the invention is to provide a vehicle of this character, including skis supported on a fully suspended frame, the frame being constructed so that the forward runners may be adjusted or rotated to guide the vehicle.
Another object of the invention is to provide a snow vehicle having a seat to accommodate riders of various sizes in a manner that allows said riders to position their centers of gravity for maximum speed and control.
Another object of the invention is to provide a snow vehicle having skis, the front ends of which will tilt up to accommodate various terrains but which will only tilt down in front to a position parallel with the rider's seat.
Another object of the invention is to provide a brake means whereby the forward movement of the snow vehicle will be slowed at the will of the rider.
Another object of the invention is to provide independent suspension to each of the skis to create a more comfortable ride and to give the rider more control over the vehicle.
With the foregoing and other objects in view which win appear as the description proceeds, reference is made to the appended drawings and the following description thereof which will illustrate a form of the invention by way of example and not of limitation, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention claimed.
