RICHARD YVATSON, OF DETROIT, MICHIGAN, ASSIGNOR OF ON EHALF TO JOHN GRANT, OF SAME PLACE.

VELOCIPEDE.;

SPECIFICATION forming part of Letters Patent No. 363,189, dated May 17, 1887.

Application filed January I3, 1857. Serial No. $221,178. (No model.)

To @ZZ whom it may concern:

Be it known that I, RICHARD WAVTsoN, of

Detroit, in the county of VVayue and Stale of to the accompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements in tricycles.

The invention consists in the peculiar construction and arrangement of sprocket-wheels and the drive-shaft for rotating the rear axle directlyby the pedal action, in theeonstruetion and application of means for regulating the tension of the drive-chain, and in the peculiar construction, arrangement, and combination of the various parts, all as more fully hereinafter set forth.

Figure l is a perspective view of my improved tricycle, and Fig. 2 is a top plan of the same. I Fig. 3 is a detail, referred to hereinafter.

In the accompanying drawings, which form a part of this specification, A represents the backbone, which supports the seat B. The forward end of this backbone is pivotally secured to the steering rod or pest C, while its rear end is bifurcated, as shown, and is provided with proper bearings for the rotating shaft D, which carries the rear Wheels, E. The lower end of the steeri'ngpost C is bifurcated, as shown, and carries the steeringwheel F.

G are parallel reach-bars, the forward ends of which are connected to a Y-piece, H, the latter being pivotally secured in any proper manner to the steeringpost. The rear ends of these reach bars or rods G are bent outwardly and secured to the bifurcated arms of the backbone. Y

I is ayoke, the upper end of which is secured to the backbone, while the lower ends of such yoke engage with T-pieces J, which form the upper half of alclamp-box, K,(shown in Fig. 3,) being provided with a journalbearing, L, for the reception of the shaft M, to which is secured the treadle-levers N.

O is a sprocket-wheel secu red upon the shaft M between the arms of the yoke I.

P is a similar sprocket-wheel secured upon the rear axle or shaft, D, and R is an endless drive-chain,.engaging with and driven by these sprocket-wheels. ends ofthe yokeI to the rear bars in the manner described, it will readily be seen that the lower ends of such yoke can be readily moved forward or backward by releasing the clampboXes and again securing them to the reachbars, thereby affording efficient means for taking up the slack or regulating the tension of the drive-chain.

The sprocket-wheel O, being much larger in diameter than the wheel l?, enables the rider to propel the machine at a veryhigh rate of speed. He has also all the benefits that may arise from the use of a bicycle without the danger of upsetting or taking headers W'hat I claim as my invention is 1. A tricycle-frame consisting of the backbone A, steering-post C, reaeh-bars Cr, and

yoke I, all connected together, and the Y- shaped piece H, connecting said reach-bars and steering-post, substantially as described.

2. The combination of'the backbone A, steering-post C, and reach-bars G with the yoke I and clamp-boxes K on said bars, and engaging the lower end of said yoke, said boxes being formed of T-shaped pieces J, substantially-as and for the purposes described.

3; In a trieycle, the combination of the backbone A, steering-post C, pivotally secured to the forward end of said backbone, shaft D, wheels E F, reach-bars G, pivotally secured at their front ends tothe post C, yoke I, adjustable upon the reach-bars G, clampboXes'K, shaft M, treadle-levers N, sprocketwheels O I), and drive-chain R, when constructed, arranged,and operating substantially in the manner and for the purposes specified.
