FIGURE X.

The present machine is built as a self-moving cart, provided that one gives it a motor, using the wind. By turning the small gear B, it moves the toothed wheel A, with the force and motion of which the two wheels E F will move along the ground, which are fixed to the shafts M N where the toothed wheel A is fixed. Consequently, the other two move as well, forming a four-wheeled cart. Keeping the shaft of the small gear firm and straight, the four bars of the cart are joined with that I K H D, and the operator G, with the rudder C, steers the path as seen.
