- UNITED STATES PATENT I OFFICE.

WILLIAM RUMSEY, OF DETROIT, MICHIGAN.

TWO-WHEELED VEHICLE.

SPECIFICATION forming part of Letters Patent No. 361,325, dated April 19, 1887- Application filed January 22, 1887. Serial No. 2,25,059. (No model.)

ToaZZ whom it may concern:

Be it known that 1, WILLIAM D. RUMSEY,

a citizen of the United States, residing at Detroit, in the county of XVayne and State of Michigan, haveinvented certain new and useful Improvements in Vehicles; and I do declare the-following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it apperx o tains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention in vehicles relates to that class 5 known as road-cartsf and it consists inthe construction of parts, allowing a vertical adjustment of the main spring, the seat-frame, and seat; also, the mounting of the seat on the frame by means of a spring or springs, so as to allow the seat-frame to rock by the horse-niotion imparted to it, the seat retaining its normal horizontal position, the object being to construct a cheap and durable device in which the horse-motion of the seat-frame is counter- 2 5 acted by the spring or springs attaching the seat to the frame; also, to enable raising or lowering the seat and its frame to locate the driver on a proper plane, as in driving a high or low horse; and my invention consists in the 0 organization of parts, as hereinafter specified,

and indicated particularly in the claims.

In the drawings forming a part of the specification, Figure l is a perspective of myinvention having the wheelsbroken away and por- 3 5 tion of the thills and seat-frame. Fig. 2 is a side elevation showing forward end of the thills and seat-frame dropped or lowered, in

whichthe dotted line 2 2 indicates the raised portion of the seat-frame. Fig. 3 is an en- 0 larged detail in perspective.

In the drawings, A represents the axle; T, the thills; H, the platform; B, the seat-frame, and S the seat. All of said parts are in common use and need no special reference.

The platform H consists of parallel strips 2, mounted on curved braces mm, having their rear ends attached to the seat-frameB B. The frontends are hooked into eyebolts r, anchored in the transverse bar R of the thills. (See Figs. 1 and 2.) The rear ends of the thills are firmly attached to the axle A by means of the strap-irons n n.

Fig. 3 shows one of the spring-attaching heads for supporting adj ustably the spring F. To the rear ends of the thills and on the inner faces, I attach said heads in an upright position by the bolts 0 a passing through the thills and the holes a a in the horizontal arms 0 0 of the heads J. The lower end of each head is provided with the right-angle step d, having a stud, e, projecting from the under face and having the upturned lip or flange i at the free end of the step d. The rear ends of the thills lie upon the steps (I, the flanges i i overreach the outer faces of the thills, and the studs 6 e enter a depression or chamber, 3, formed in the upper face of the axle A, whereby the studs prevent lateral movement of the thills on the axle A. The body of each head J is provided with a series of holes, 6.

The ends of the spring F are adj ustably attached to the heads J by means of the arms N N, having their outer ends adjustably secured to the heads by means of the bolts 4 4. The inner ends of the arms N N are secured to the ends of the spring F by the bolts5 5, whereby the spring has a vibrating motion.

The head-block D, mounted on the spring F, receives the curved brace E, and by the clips Y Y said parts are bound together. The ends of the brace E are journaled in boxes Z Z, on the under face of the seat-frame B B.

The seat S is mounted on the rear ends of the seat-frame by means of the U-shaped springs G O. Said springs I locate in sets of two under each end of the seat, (see Fig. 2,) having their curved ends actfacing each other, being located under the center of the seat. Thelower ends of the springs are attached to the seat-frame. The upper ends are attached to the seat.

It will be observed from the foregoing construction that when the thills are elevated, as in Fig. 1, the seat S stands on ahorizontal line and parallel with the seat-frame; but when the thills are lowered, as in Fig. 2, by the motion of the horse, the seat, by the weight of the driver, retains its normal horizontal position. The position of the seat in Fig. 2 is obtained by the closing of the rear :springs O and the opening of the forward springs G.

When the thills are raised by the horse-mo- ICO tion to the dotted line 2 2 of Fig. 2, the springs O G will stand as in Fig. 1.

It will be observed that the construction of the springs O O is such that the seat S has no np-and-down motion at the longitudinal center.

The main object of the springs G O is to allow the seat-frame B B to rock, or its rear end to rise and fall and not alter the horizontal position of the seat by a tipping of theseat. This I consider a very important feature of my invention, as the horse-motion is counteracted by the construction or manner of mounting the seat on its frame.

The seat and frame are raised and lowered, to bring the driver to a proper height for his horse, by placing the bolts 4 4 through such a set {of holes, 0 e, in the heads Jas will obtain the desired height.

Having set forth myinvention,\vhat I desire to cover by Letters Patent is- 1. In combination with the axle, the thills, the seat-frame attached thereto and having a central support, and the seat and spring or springs located between said seat and the seatframe, whereby the horse-motion imparted to the seat-frame is counteracted, as and for the purposes specified.

2. In combination with the axle, the thills i l l rigidly attached thereto, the seat-frame having its forward ends pivoted to the thills and having pivotal connection with the brace E, said brace being mounted on the spring F, the seat, and U shaped springs connecting theseat with the seatframe, substantially as specified.

3. In combination with the axle, the thills rigidly attached thereto, the seat-frame and its seat, the brace E, having its ends pivoted to the seat-frame, the spring F, and mechanism connecting the spring with said brace,the ends of the spring F being adjustably attached to the heads J, substantially as set forth.

4. In combination with-the axle, the thills rigidly attached thereto,the heads J,eonstrueted as set forth, the spring F, and arms N,with bolts connecting the spring adj ustably with the heads, and the seat-frame mounted on said spring, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

\VILLIAM D. RUMSEY.
