This invention relates to the propelling of vehiclesfor practical use, and consists of the spring and wheel-work mechanism attached thereto, as will be set forthin the following.

The other end of the spring is attached to the shaftof the wheel H, in the usual manner. By this invention, vehicles may be propelled oncommon roads, with more or less speed, according to the level or uneven character of the road. Its advantage, in dispensing with the use of horses,is obvious. I claim as new, and desire to secure by LettersPatent,— 1.
