MPROVEMENT IN VELQCIPEDES.

The Bobadilla referred to in. these Letters Patent and making part of the lame.-

Ifo all whom it may concern.-

fullmproveinents in .Velocipedes; and we do hereby declarethatthe following is a full, clear, and exact de-` scription thereof, reference being had to the accompaymg drawings, making part of this specification, in

l which- 'Figure 1 is an elevation of our velocipede complete'. Figure 2 is atop view of the same, with the rear u portion of the seat-spring broken away.

` ing one 'of the drums and pulleys in section.

IFigure 5 is a perspective view of one of the springboxes on a portion of one of the rear forked ends of the perch connecting the two wheels.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates particularly to improvements on two-wheel carriages or velocipedes, and consists#- First, in giving a progressive rotary motion to the rear wheel of the carriage by means of belts passing over pulleys, and connected at their @ont ends to treadles or stirrnps, and at their rear' ends to pulleys, which are applied upon the outer surfacesof drums that act upon pawls upon the ends of said wheel, said drums being applied loosely upon the axle of the driving-wheel, and acted upon ,by springs applied in boxes upon the rear bearings of the perch in such -manner that they operate to turn the wheel in one direction v only, and while being retracted or turned backward in conjunction with the loose and fixed pulleys as a means of enabling the rider to apply greater power While ascending hills than is required when moving over level roads, as will be hereinafter explained.

We are aware that E. K. W. Blake obtained Letters Patent of the United States on the 17th day of November, 1868, on a mode of propelling a velocipede .having two rear wheels and one guide-wheel by the application of loose hollow pulleys on the drivingaxle, having pawls taking into ratchets within the said pulleys secured to the axle, and belts for operating the pulleys passing over guide-pulleys at the front of the machine to the hands of the operator, whereby be may propel the machine by pulling from directly in front of him.

This plan of Blake is not applicable to the rear wheels of a two-wheel carriage, and islattended with noise andA other objections, which we obviate by our improved arrangement and construction -of devices.

We are also aware that George R. Metten, one of the applicants under this petition, filed an application for Letters Patent, ou the 21st day of January, 1869, in which he described a mechanical movement-'consisting of oscillating hollow drums applied loosely upc'n tle shaft of a balance-wheel and adapted for coniinnnicating through the medium of spring-clutch arms, a continuous rotary motion to said balancewbeel.

invention, we will describe its construction and operation. l

In the accompanying drawingsf A A represent two wheels, which are arranged .in the same vertical plane, and connected together by means of abcurved reach or perch, B.

ceives between the arms thus formed the drivingwheel A, the-axle@ of which is secured at its ends to the extremities of these arms.

vThe front elevated end of the perch B has two vibrating arms or treadles D D pivoted to it at e, in

is formed on the perch for the purpose of-receiving the journal portion O' of the forked standard O'of steering-wheel A.

To the upper end of the journal O, handles a a are seat G', can turn the standard O to the right or left hand,`and thus guide the carriage.

The seat or saddle G is secured to an arched spring, G, whichv is pivoted at i near the tubularI bearing o', and at tto the upper end of standard B', rising from the rear forked ends of the perch, as shown in fig. 1.

The vibrating treadles D D, which are arranged on opposite sides of the front guide-wheel A' are provided on their free ends with foot-rests t t, and also with adjustable clasps or eyes dd, which latter can be adjusted ments e e of said levers, as may be required.

To the clasps-d d, cords or belts c c are fastened at g, beneath seat G, and thence attached by rings or snaps. g2 to loose pulleys, which are fastened by their blocks to cords or belts that pass over and are fastened to pulleys jj upon the outer ends of two hollow drums J J. ,A

The drums J J are disks having hanged perimeters, and these drums are applied loosely upon the axle p of the rear wheel A and arranged on 'opposite sides of this wheel, as shownin iig. 4.

The outwardly extending hub of each drum J is connected to one end of a Ivolute spring, S, whose up posite end is attached to the flange of a circular box To enable others skilled in the art to understand our The rear portion of this perch B is -forked and rev rear of whichva tubular eye bearing, c, rises from and applied, by which the rider, while sitting upon the and set nearer to or' further from the pivotfattachtheir front ends, carried back and passed over pulleys h, which box encloses the spring and is formed on or secured to the rear end of the perch B, as shown in igs. l, 2, and .5.

The object of the spring S S, in boxes It It, is to retract or wud the cords or bands c c3, upon their pulleys jj after every forward stroke of the treadles, thereby assisting the rider to retract or lifthis feet, and at the saine time keeping said drums always in proper position for acting upon the wheel A, as will be hereinafter further explained.

To each end of the hub fr of wheel A, three arms, k k k, of equal length, are pivoted at equal distances apart around its axis, and at points concentric to its axis, the outer ends of which arms have segmental dogs, o, pivoted to them at o.

The outer convex surfaces of the dogs o are serrated and adapted to act against the inner surface of the flange of their enclosing drum J, which surface may be covered, as at n, figs. 3 andv 4, with leather, or other suitable substance, to produce friction between it and the said dogs.

It will be seen that the arms of the dogs 0 are all tangent to the circumference of the axle p, and that these arms are acted upon by springs l, pressing against stops n' on the hub r; consequently when either one of the drums J is turned in the direction indicated by arrows iu figs. l, 2, and 4, the surface -n will act upon the serrated surfaces of the dogs and cause the arms k to press these dogs outwardly, and thus bite the drum so as to clutch or engage it with the wheel A.

' When either one of the drums is turned backward by its spring S, the free ends of the arms k will re tract the dogs o and allow su'ch drum to turn freely around the axle p of the wheel A without turning this 'vheel5 and when either one of the drums is acted upon l by the cord or belt c to turn Wheel A, the dogs o of the opposite drum will bc retracted and allowed to revulve around axle p, with their Wheel A, without turning or acting upon this drum.

Thus, it will be seen that the wheel A can be turned g2 g2, as indicated in red lines, fig. l. This will give the rider a greater obtained at an expense of speed.

Instead of attaching the front ends of the cords or belts c c to vibrating treadles, these ends may have purchase though which latter instance thefrout wheel would be guided by the feet.

Having described our invention,

What we claim as new, and desire to secure by Letters Patent, s-

l. The arrangement of the drums J J, shaft p, wheel A, springs S, elutcbing-pawls, belts c, and treadles D D, in combination with the wheel A', frame or perch B O', and seat G', substantially in the manner and for the purpose described.

2. The arrangement of the device g, hook g, and cord c, in combination with a velocipede, which is constructed and operated substantially as described.

3. The combination and arrau ement of the devices (l, cords c, and treadles D D, w th a velocipede, constructed aud operated as herein described.

4. The arrangement and combination of the guiding-lever C, seat G, treadles D D, perch or frame B, cords c c, drums and clutching-pawls, springs, and tracking-wheels A A', substantially in the. manner shown and described have to EDWIN COWLES.
