GEORGE E. SPARE, OF NEW HAVEN, CONNECTICUT.

TWO-.WHEELED VEHICLE.

SPEGIFIOATION forming part of Letters Patent No. 274,40I, dated March 20, 1883.

Application filed December 7, 1882. (No model.)

To all whom it may concern:

Be it known that I, GEORGE E. SPARE, of New Haven,in thecounty of New Haven .and State of Connecticut, have inventeda new Improvement in Two-Wheeled Vehicles; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specificatiomand represent, in

Figure 1, a side view; Fig. 2, a rear view; Fig. 3, atop view; Fig. 4., a side view, showing the attachment of the shaft enlarged.

This invention relates to an improvement in two-wheeled vehicles, the object being to adapt to such vehicles what is known as a buckboard-body; and it consists in the construction, as hereinafter described, and more particularly recited in the claim.

A is the axle, provided with the u-sualtwo wheels, B. I

To the axle, at each side, a longitudinal semi-elliptic spring, 0, is rigidly fixed, prol) is a body composed of thin wood, commonly known as buckboard. It is secured at each end to a crossbar, E, but free between the bars forthe natural elasticity of the wood of which the body is composed, substantially as in the usual construction of buckboards.

The respective ends of the spring Gv are hung to the cross-bar by means of a link, F, as seen in Fig. 2, which permits the connection to swing to adapt itself to the varying curvature of the spring.

On the body the usual seat, G, is arranged about midway of the length of the body,

and should be substantially over the axle, as shown. V

The shafts H are arranged one each side, and extend over the spring 0, as seen in Fig. 4. They are connected to the axle by a bar, I, which rests upon the spring, so that the same clips, (1, which secure the spring secure the bar I. The forward end of the bar I is hinged to the shaft H, as seen at a, Fig. 4, and the rear end of the bar is connected to the shaft by means of a bolt, f, provided with a nut, h, above the bar, and a corresponding nut, 6, below the bar, the bar being clamped between the two nuts, the bolt fixed to the shaft. By this construction the elevation of the shafts may be adjusted-that is to say, it the horse be taller the rear end of the shaft is lowered by turning the nut h onto the bolt, permitting that end of the shaftto drop. Then the lower end, t', is screwed up against the bar to make engagementbetween the bar and the shaft firm and strong. If the shaft is to be lowered, reverse the operation. This adjustment is desirable in this particular buckboard class of two-wheeled carriage, for the reason that the tipping of the carriage by the raising 0r lowering of the shaft will be more apparent in a carriage of this class than in the usual full-body two-wheel carriages. Thus constructed the carriage has all the desirable advantages of a buckboard, with all the de sirable advantages of a two-wheeled carriage.

While I prefer to hinge the bar I to the shaft forward of the axle, and make the adjustment to the rear, this may be reversed. Instead of attaching the bolt f to the shaft and making the adjustment upon the upper and lower side of the bar I, the bolt may be attached to the bar and extend up through the shaft, with the ends it 1' respectively above and below the shaft.

I do not wish to be understood as claiming, broadly, making the shafts of a sulky adjustable with rclation to the body, wherebythe plane of the bod y may be varied with relationv to the plane of the shafts, as such,I am aware, is not new.

I claim- The herein-described two-w heeled carriage, consisting of the axle carrying the two wheels, the half-elliptical springs 0, attached to the axle and extending to the front and rear, the bodyhung by its front and rear end to said springs, the shafts attached to the axleby a bar extending to the front and rear of the axle, one end of said bar hinged to the shaft, the other secured by a vertical bolt, f, and two adjusting-nuts, h i, substantially as described.

GEO. E. SPARE.
