Vehicle.

Patent for a new and improved horse carriage. This design calls for "the rider [to] press the treadles so as to hold the wheels in contact with the ground. When sufficient speed has been acquired the treadles are released, and the springs will then raise the wheels from contact with the ground, and the momentum will then be sufficient to keep the wheel erect. Should it be inclined to tilt, it may easily be righted by pressing either treadle so as to throw the wheel on the tilting side in contact with the ground" (lines 61-74)
