VELOCIPEDE.

SPECIFICATION forming part of Letters Patent No. 259,222, dated June 6, 1882. Application filed March 28, 1882: (N0 model.l

To all whom it may concern Be it known that I, GEPHAS SHELBURNE, of Johnson City, in the county of Washing ton and State of Tennessee, have invented certain new and useful Improvements in Velocipedes,'0f which the following is a full, clear, and exact description.

The object of my invention is to facilitate the propulsion of velocipedes by foot-power.

The invention consists in a velocipede with either three or four wheels, provided on its driving-shaft with a cog-wheel,which is driven by another cog-wheel mounted on the same shaft; with ratchet-wheels with which pawls engage, pivoted to the ends of rocking levers connected by pivoted connecting-bars, with a crank-shaft provided with treadles for operating it, whereby the driving-wheels will be rotated by operating the crank-shaft.

Reference is to be had to the accompanyin g drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a longitudinal sectional elevation of a four-wheeled velocipede of my improved construction. Fig. 2 is a plan view of the same. Fig. 3 is a longitudinal sectional elevation of a three-wheeled velocipede or tricycle of my improved construction. Fig. 4: is a sectional plan view of the same. Fig. 5 is a detail perspective view of the standards on the axle.

Beferrin g to Figs. 1 and 2, the driving-wheels A are rigidly mounted on the axle B, which is journaled in the rear parts of the side bars, G, of the vehicle-frame, the front ends of these bars being swivcled on the bent front axle, D, jonrnaled in the hubs of the front or steering wheels, E. A crank-shaft, F, provided with two opposite treadles, a, and at the ends with two opposite crank-arms, I), is journaled in the front downwardly-projectingends of the bars 0. Two levers, G, are pivoted to the bars (1 directly above the axle B, and the front ends of these levers are pivoted to the upper ends of connecting-bars H, having their lower ends pivoted to the crank-arms bof the crank-shaft F. The rear ends of the levers G are provided with pivoted pawl-hooks I, which hang down- -5o ward, these books being adapted to catch on the teeth of ratchet-wheels J, mounted on a I shaft, K,journaled in the rear projecting ends of the arms 0 to the rear of the driving-axle B. On this shaft K a large cog-wheel, L, is mounted, which engages with a smaller cogwheel, M, rigidly mounted on the driving-axle A. A seat, N, for the operator rests on the front ends of the bars (3, and a seat, 0, for passengers rests on the middle or rear parts of the bars 0. A vertical steering-rod, P, is journaled in front of the operators seat N, and is provided at its upper end with a cross-handle, Q, and at its lower end with a sprocket-wheel or pulley, R, around which a chain, S, passes, attached at its ends to the front axle, D. By

working the crank-shal't'F the levers G willbe rocked and the pawl-hooks I will catch on the teeth of the ratchet-wheels J and rotate the same and the wheel L, which rotates the wheel M and the driving-shaft B.

Referring to Figs. 3, 4, and 5, the drivingwheels A are rigidly mounted on the shaft or axle B, which is joul'naled in the lower part of an upright frame, 0, resting on this shaft or axle, to the upper part of which'frame G the upper end of the curved reach D is pivoted-or swiveled. A wheel, E, is journaled in the lower forked end of the curved reach D. The operators seat N rests on the curved reach D. The frame 0 is provided with two forward-projecting arms, 0, in the outer ends of which a short shaft, K, is journaled, on which shaft are rigidly mounted two ratchet-wheels, J, and between them a cog-wheel, L, which engages with a cog-wheel, M, rigidly mounted on the shaft B. Levers G are pivoted to the ends of the arms 0, and'these levers are provided at the outer or front ends with pawlhooks 1, adapted to catch on the teeth of the ratchet-wheels J. The inner or rear ends of these levers G are pivoted to the upper ends of connecting-bars H, pivoted to the opposite treadles, a a, of a crank-shaft, F, journaled in the lower ends of arms S, projecting from the bottom of the'frame O. The frame 0 is pro-- vided at its top with a transverse handle, J,

for turning the front wheels and the frame 0. A brakeshoe, U, is attached at one end to a rod, V, attached to a lever, W, pivoted on one arm 0, to the other end of which lever W is pivoted a rod, X, pivoted to the outer end of a hand-lever, 'Y, pivoted to the frame 0. By

depressing the inner end of the hand-lever Y the brake-shoe U will be pressed against the tire of one of the wheels A. By operating the crank-shaft F the levers G will be rocked and the hook-pawls I rotate the ratchet-wheels J and the wheel L, which in turn rotates the wheel M and the shaft B.

Having th us described my invention, I claim as new and desire to secure by Letters Patent- 1. In a "e1ocipede,the combination,withthe driving-wheel shaft, of cog-wheels and ratchetwheels for rotating the same, rocking levers and pawls for acting on these ratchet and cog wheels,andacrank-shaftprovided with treadles and connected with the rocking levers by means of pivoted connecting-bars, substantially as herein shown and described, and for the purpose set forth.

2. In avelocipede,the combination, with the driving-wheel shaft B, of the cog-wheels L and M, the ratchet-wheels J, the pawls I, the rock ing levers G, the connecting-bars H, and the crank treadlc-shaft F, substantially as herein shown and described, and for the purpose set forth.

3. In a velocipede, the combination, with the front and rear axle, D B, and the side bars, 0, extended beyond the said axles, of the c0gwheels L M, the ratchet-wheels J, the pawls I, the rockinglevers G, the connecting-bars H, and the crank treadle-shaft F,substantially as and for the purpose set forth.
