'TWO-WHEELED VEHICLE.

SPECIFICATION forming part of Letters Patent No.

294,528, dated March 4., 1884.

Application filed December 29, 1883. (No model.)

ments in Light Vehicles; andI do hereby de clare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification.

My invention consists in improvements in trussing the poles, hounds, axles, and seatsupports of light vehicles for driving-sucl1 as pole-carts and s'ulkiessubstantially as hereinafter specified.

I11 the drawings, Figure 1 represents a top View of the pole and connected parts of a light pole-cart to which my improvements are ap plied or with which the said parts are connected; Fig. 2, a side view of the same; Fig. 3, a top View of the similar parts of a sulky constructed with my improvements; Fig. 4, a

side view thereof; Fig. 5, a rear view of the trussed axle; Figs. 6 and 7, views showing some of the construction in detail; Figs. 8, 9, and 10, respectively, a front view, bottom trussing.

Like letters designate corresponding parts in all of the figures.

. vals by any suitable means.

' strips, a a, as shown, so as to be separated in the center First, as to the construction of the pole A. I truss it substantially in the following manner: It is formed of threetrussepieces namely, two outer strips, to a, and a central strip or brace, b. The three parts are secured together at the two ends of the pole, and the two outer are curved outwardin the middle,

as far as may be desired for strength and stiffnes's, say two or three inches. The middle piece, I), is straight,- and consequently there is equal space on both sides between it and the side pieces. The parts are connected at intervI have represented bolts 0 0 extending through the three parts, with thimbles or washers d (1 around the bolts between the parts, as shown by the cross section in Fig. 6. The strips may be all made of strong but comparatively light wood, and quite thin, not exceeding five-eighths of an inch for a light pole-cart or a sulky. The two rear end, f, of the section of my seat-support" -and stiffness are given thereto to enable outer strips may be sawed from one piece and split the full length of the trussing, and for sulkies, as shown in Figs. 3 and 4, the curved pole not being split, but whole, as shown.

. Another feature of improvement in the constructionof the truss consists in widening the middle strip, 1), in the middle beyond the width of the outer strips, a a, as shown in Figs. 2, 4, and 6. The width may be twice as great at the middle as the outer strips, and gradually narrowedto the same width at the ends of the truss. This form gives great rigidity and strength to the pole in the vertical direction, while the bending outward of the outer strips gives sufficient rigidity and strength horizontally. Thusa very strong as well as light pole is formec This construction is applicable to the poles of all kinds of vehicles. It is obvious that this feature of widening a strip, 2), is-applicable also to two strip trusses as well as three-strip trusses, either one or both strips being thus widened in the middle.

The next feature of improvement consists in splitting and trussing the fore part of the houndsB B, Figs. 1 and 2, forward of the cross-brace g. The bulging out of the two sides h h of the trusscd part and the stays or braces between stiffen the hounds greatly with out increasing the material and weight. The rear curved parts of the hounds are preferably retained whole without trussing.

Another feature of my invention consists in formingatrussed arched axle D, substantially as herein described, whereby sufficientstrength me to dispense with a straight brace-rod extending from spindle to spindle of the axle. The arch is made high, and is trussed by combining two arched strips, 6 j, of different degrees of curvature, as shown in Fig. 5, so that the strips are united at the two ends where they are joined to the spindles 7c 70, and separated farther and farther toward the middle. They are braced together at intervals, preferably by means of double clips Z Z, as shown in Fig. 7. The strips 13 j are suitably made of fiat form on the adjacent sides, but rounded on the outer sides. For a sulky, the body may rest directly on a flattened or straight portion, m on the highest part of the upper strip, 7?; or an elliptic spring may be mounted on this strip under the seat.

Another feature of myinventiou consists in my improvedseat-support trussing for these light vehicles, as shown in Figs. 8, 9, and 10. Let D represent the axle or upper trussstrip of the axle; E E, side shafts; F G H, crossbars between the shafts, and I the seat or seatframe.

First. I employ a T-shaped brace, 01, coir necting the seat I and front cross-bar, F, in the middle, as best shown in Fi g. S. This not only supports the seat in the middle of the front part thereof, but braces it against side rackin It also forms, in connection with two inclined side braces, 0, between the seat and said cross-bar F a complete truss, producing great strength and firmnessin the sup port, though the parts may be quite slender and light.

Secondly. This front brace, 21, in connection with a brace, 1), extending from the cross braces, or braces F G, to the axle l), or a clip, q, thereon, a brace, 1', extending fromtheaxle or the said clip thereon to the rear cross-bar, H, and a brace, 8, extending from the crossbar H to the seat I, forms a complete trnssing of the parts from front to rear.

I claim as my invention- 1. A trussed vehicle-pole formed of two outthe middle and narrow at the ends, for the purpose specified.

3. In combination with a vehicle-pole, hounds trussed in the part forward of the cross-brace, substantially as and for the purpose herein specified.

4. Au arched axle trnssed with two arches of different degrees of curvature, substantially as set forth.

5. The T-shaped brace 11, in combination with the cross-bar F and seat I, for the purpose specified.

G. The combination of the brace 01, braces 0 o, cross-bar F, and seat I, substantially as and for the purpose herein specified.

7. The combination of the braces n p r s, cross-bar F, axle D, cross-bar H, and seat I, substantially as and for the purpose herein specified.

In testimony whereofI have signed my name in thepresenee of two witnesses.
