IMPROVEMENT IN VELOCIPEDE.

The Schedule referred to in these Letters Patent and making partici the same'.

To whom it may concern:

. being a part of this specification, in which- Figure 1`,sheet 1, is a side elevation of my carriage,

partially in section;

Figure 2 isa plan of the carriage, with the seat and top removed;Y

Figure 3, sheet2, is a rear elevation of the onerating gearing;

Figure LLis a bottom-plan of' the' saine, with the caps of the spring-barrels removed; and

Figure 5 is a vertical longitudinal section of one of the hubs. Similar letters of reference indicate corresponding parte in each figure.

.Ihe nature of vthis invention relates to the construction of a self-propelling carriage, whose motive' power is derived from two or more coiled spxingsrotating the rear axle thron'gh a peculiar system of gearing.

It consists'- p First, in the peculiar'constrnotion of the hubs of the rear wheels, and arrangement ot' clutch-boxes therein.

Second, in the mechanism for winding up both springs simultaneously, by the rider, in his seat.

Third, in the peculiar arrangement of the train of gearing for communicating motion to the axle in either direction, such direction being changed at the will of the rider.

Also, in the general arrangement of its various parts, as hereinaiter more fully shown and set forth.

In the drawings- A represents the body of a light 'carriage,' and B an axle journaled in the rear part thereof', and on whose arms rotate the driving-wheels C.

D is a single-fore wheel, jonrnaled in the bifurcated ends of thev standard a, which supports the-crane-neck of the carriage-body. y

The standard extends up through a hollow postA on hbe'crane-neck, andl is partially rotated byv the tiller h, carried back toward the riders seat, for conven-V lntlygovernng the course of the vehicle.

18a-frame, erected in the rear part of the carrustige/body l @are .spring arbors, journaled in said iiame, to which are Secured the inner eiids of the coiled springs F, whose enter endsare secured to the barrels Gr which inclose them, said barrels rotating freely o n theirarhors, and are provided with a spur-gearing on their -when thrown outward.

npper edges, which engage with and rotate an upright shaft, H, through a pinion, H1.

At the top ofthe shaft H is a spur-wheel, H2, which communicates motion to a shaft, I, through a pinion, Il.

.At the lower end of this shaft is a imiter-gear, I, which gives motion to a horizontal shaft, J, through its pinion, J1. v

At the 4rear end of the shaft J is a ruiter-gear, J, which gives motion to the axle B through one of its pinions, K or K, with either of which it may be caused to mesh, the shaft having alateral movement in its rear box for that purpose.

L are the hubs of the driving-wheels, which are hollow, and have a clutchTbox, d, within them.

. e is a clutch-pin, sliding in a key-way in the axle, its outer' end engaging witlrthe clutch-box in the hub, Otherwise the hub rotates freely on the axle.

The inner end of the clutch-pin is provided with a projecting stud, with which engages'aspring, j, coiled about the axle, its other 'end being secured to a clutch- These collars are moved to or fronlthe hubs, causing the clutch-pin to engage or release the hubs, by bellcianks, N, operated by a rock-shaft, O, lever O, and links 0 2, under the riders seat, one of the belly-cranks having a lateral link, P, connecting it with the shaft J. By depressingthe lever 0 1, the pinion Jis thrown in gear with the pinion K of the axle, at the same time the clutch-pin of the left'wheel is caused to engage with its hub, and a forward motion givento the axle from the springs F through the train described. yThe reversing of the motion is eiected by throwing'l up the lever O', and causing the' gear Jto mesh with the pinion K' l A friction-brake, Q, operated by a vtreadle, Qaet ing on a drum on the vertical shaft I, retards the motion of the vehicle when necessary.

, To wind up the springs, a shaft, R, provided with crank R1, is jonrnaled atthe side ot' the seat. At its rear end is a miter-gear, R, which meshes with the pinion S of the transverse shaft S over the barrels, and rotates said shai't,

On the arbors c above the barrels, worm-wheels, T, are secured, with which mesh -worms U on the shaft S. By turning the 'crank R', both springs are wound up simultaneouslyby the rider, as often as may bc necessary, without leaving his seat. As the speed of each succeeding wheel in the train from the arbor increases, it will read-ily he seen that, with springs of the proper size and power, a long distance may be' `traveled without re-winding the'springs.

What I claim as my. invention, and desire to sccureby Letters Patent, vistion with the arhors c, in the manner and for the purpose set forth;

3. In combination with the foregoing parts, the body A, wheels O D, standard drand tiller b, the whole constructed, arranged, and operating substantially as described.
