TWO- -WHEELED VEHICLE.

SPECIFICATION forming part of Letters Patent No. 399,650, dated March 19, 1889.

Application filed January 16, 1888. Serial No. 260,907. (No model.)

To aZZ whom it may concern:

Be it known that I, IRA BROWN, M. 1)., of Milford, Iroquois county, Illinois, have in vented certain new and useful Improvements in Two-VVheeled Vehicles or Road-Carts, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Heretofore, although many have been the attempts, the effort to do away with the horsemotion in two -wheeled vehicles has to a greater or less extent proved to be a failure.

The object of my invention is to produce a road-cart or other two-wheeled vehicle 'in which the horse-motion is entirely gotten rid of, and in which a steady even riding motion is experienced, substantially as hereinafter described, and as illustrated in the drawings, in which Figure 1 is a side elevation of my improved road-cart. Fig. 2 is a plan View of the same. Fig. 3 is a detail view showing the arrangement of springs thereof.

Reference being had to the drawings, A A represent the shafts, preferably having their rear extensions curved downward and to the rear, and having their rear ends, a, terminating a suitable distance back of the axle B, as shown. Near the ends a of the shafts they are each provided with a vertical hole, a, therein, through which passes a vertical stud, I), which arises from the arm 0. The arms 0 C are clipped transversely to the axle just a little beyond the inner side faces of the shafts, and the rear ends, from which the ver tical stud b projects, are deflected outward slightly, so as to come under the holes a a of said shafts. The forward ends, 0, of these arms extend a short distance toward the front of the vehicle and then project at about right angles out under the shafts, forming a fulcrum, cl, upon which the shafts rest and rock. Secured to the upper surface of the shafts, about over the fulcrum d, are the leaf-springs D, which extend longitudinally to the rear to and over the holes a in the shaft, where they are provided with an aperture in alignment with said hole, through which stud b likewise passes. These leaf springs press upward against the heads of said studs. hen, therefore, the rider is in the seat of the vehicle and his weight is so adjusted as to bring his center of gravity to the rear of the axle, the rear ends of said shaft naturally oscillate upward off of the ends of arms 0 O and vibrate between the base and heads of the stud without imparting the horse-motion thereto. Instead of leafsprings, as described and shown, coil-springs could be placed around said studs, between the shafts and the heads thereof, and, if desired, between the base of said studs and the shafts. I prefer the leaf-springs, however.

Clipped to the axle, preferablyimmediately over and by the same clip as fastens the arms C thereto, are the body-sprin gs E. These bodysprings are preferably sort of -shaped that is, they pursue a horizontal straight course toward the front of the vehicle until about beside the dash-board, where they are obliquely to the rear, in toward each other bent back and pursue a course, preferably and upward at an angle of from thirty to forty-five degrees. On the upper ends of these springs E is secured the seat F, and it is preferably secured to said springs so as to be adjustable longitudinally. To accomplish this adjustability in a simple manner, I provide longitudinal slots 6 in the side strips of the seat-frame and run a bolt, 6, up through suitable bolt-holes in said springs, which has a thumb-nut, f, on its lower threaded end, by loosening which the seat can be adjusted longitudinally within the limits of said slots 6, and by tightening which said seat may be securely held in such adjusted position.

Instead of the -shaped springs E, the ordinary elliptical carriage-springs or the platform spring could be used. I prefer the springs shown, however. Secured to and depending vertically downward from near the upper ends of the springs E or from the seat are the rods G, 'which support the basket H. These rods depend vertically downward from said seat to just in front of the axle, and are then bent forward correspondingly and have the transverse floor-strips of the basket secured to them. Their forward ends are suitably secured to a transverse bar, h, which is held in the ends of the fiat springs g g, which latter are clipped to the axle independent of springs E, or, as I prefer, secured to said axle by the same clip as secures arms 0 and springs E thereto.

If desired, a dash-board may be provided which can be secured to iron brackets arising from the transverse bar It or from the flat spring g.

What I claim is 1. A two-wheeled vehicle provided with a suitable seat, springs for supporting said seat above the axle, and said axle, in combination with the shafts, the rear ends of which extend back of the axle and have vertical apertures therein, and arms 0 0, having studs 1) rising from their rear ends, and having their forward ends bent at right angles to its length, as set forth.

2. A two-wheeled vehicle provided with a longitudinally-adjustable seat, springs for supporting said seat above the axle, and said axle, in combination with shafts A, having their rear ends extended back of the axle and provided with holes a therein, arms 0 O, and studs h, arising from their rear ends, as set forth.

3. A two-wheeled vehicle provided with a suitable seat, springs for supporting said seat, and axle upon which said springs rest, in combination with arms G 0, having studs projecting from their rear ends, and springs D, as set forth.

4. A two-wheeled vehicle having asuitable seat, springs supporting said seat, and axle to which said springs are clipped, in combination with arms 0 C, as described, having studs 5 rising from their rear ends, shafts A, the rear ends of which extend back of the said axle and through which said studs pass vertically, and springs D, substantially as described.

5. In a two-wheeled vehicle, the combination, with the seat, of the -shaped supportingsprings, the axle, the springs g g, and the basket H, as set forth.

6. In a two-Wheeled vehicle, the combination, with the shafts, arms 0, having studs 1) and fulcrumal projections 61, and springs D, of the axle, fiat springs g, springs E, the seat F, and the basket H, as set forth.

'7. The combination, in a two-wheeled vehicle, with the shafts, arms 0, having studs 1) and fulcrumal projections cl, and springs D, of the axle, springs E, and seat F, said seat being provided with longitudinal slots in its side frames and secured to springs E by bolts and thumb-nuts, as set forth.

8. In. a two-wheeled vehicle, the combination, with the shafts and axle, of -shaped springs and the seat, secured thereto, said springs having their lower ends clipped to the axle, pursuing a forward course a suitable distance, and then bent back toward the rear, extending obliquely in toward each other and upward at a suitable angle, as set forth.
