This patent application used a jeep to demonstrated how the endless track system would work on a vehicle not designed specifically for tracks. The patent was filed January 13, 1955.

According to inventor Fritz Riemerschmid, “Numerous constructions of the track! laying or crawler type have heretofore been proposed, but in all of these known cases special-type vehicles are involved, the construction of which either prohibits or renders extremely difficult the use of the vehicle under normal road and travel conditions.

Accordingly it is one of the main objects of the present invention to provide a crawler-type tracklaying undercarriage for automotive vehicles which, while being particularly suitable for travel over snow-covered terrain, can be quickly and easily substituted for the standard wheels of the vehicle. It is another object of the invention to provide a construction of the type indicated in which, except for the removal of the said standard wheels from the vehicle, requires no structural changes to be made in a given vehicle. Thus, the invention renders it possible, whenever it may be desired, to provide an automotive vehicle of any given type with a tracklaying mechanism which takes the place of the standard wheels on which the said vehicle normally travels.”
