VELOCIPEDE.

SPECIICATON forming part of Letters Patent No, 288,219, dated oveznber 13, SS.

Be it known that I, LEONARD W. ELLIQTT,

invented certain new and useful Improvements in Velocipedes, of which the following is a full, clear, and exact description.

.The objectoi' this invention is the production of a vclocipede adapted to be propelled by the pull of the operator, this pull being similar to the pull of a person exercising on a rowing-machine.

To this end my` invention consists in the combination and arrangement of a drum, clutch, and convolute spring on the axle to which the driving-wheels are fixed, said clutch being adapted to impart motion to the axle and driving-wheels when the drum is moved in one direction by means of a strap wound thereonglthe other end of `which passes over a pulleysnpported by a post at the forward end of the body, and is attached to a cross-bar within reach of the operator, and allowing the drum to run free on the axle when the strap is rewound upon the drum under an impulse from the spring, the details of my invention being hereinafter fully pointed out.

In the accompanying drawings, Figure 1' is a plan view of a velocipede embodying my improvements, `the end of the body being ism. Fig. 2 isa side View thereof. Fig. 3 is a longitudinal sectional elevation of parts on a larger scale, showing-the axle, clutch, drum, and spring; and Fig. 4 is a front viewof the steering-wheel.

Similar letters of reference designate cor,- responding parts inall the figures.

A designates the body or reach of my velocipede supported between two driving-wheels, BB. and a steering-wheel, C, and having a seat,l D, thereon, arranged to slide backward and forward with the body of the operatorv as the velocipede is propelled.

a designates the axle, to which the drivingwheels B B are fixed. On this axle a a drum, I), fixed to a lmb,c, is supported to rotate loosely. v

S designates a strap,which is wound around and made fast to the drum b, and extends from the drum I, `under the body or reach A, and over a pulley, l?, supported by a post, P, to a Application filed January 26, 1883. (No model.)

cross -bar, E, having handles F F, which,w hen not in use,rest on the forward part of the body A, within conxf'enient reach of the operator.

G designates a convolute spring, spirally coiled around the hub c, one end of this spring being made fast to the said hub, and the other end being secured by a staple, y, to theV under side of the rear of the body A. The pull of the operator on the cross-bar E, as he moves backward on the seat D, unwinds the strap S Y from the drun b, and rotates the drum b in a forward direction, and as the operator moves forward on the seat D the spring s,.bearing against the hub c, reverses the action of the drum, and the strap is rewound on the drum.

d ddesignate a clutch, which is combined with thedruln b and axle a for the purpose of transmitting motion to the axle from the drum when the latter is moved in one direction under an impulse from the strap, and of allowing the druin to run free of the axle when the strap is being rewound upon the drum under an impulse from the spring. A This clutch consists of a female part, d, which is rigidly afxed to the axle, and a male part, d', which is rigidly affixed to one side of the drum, and is unconnected with the axle. The interior ofthe female part d of this clutch is of cylindric shape, andthe male part d is provided on its exterior with arched-shaped surfaces, which are eccentric to the interior of the female part. Between the female part and the eccentric arched-shaped surfaces of the male part are dogs di, which are made of cylindric or spherical shape. To force and hold the dogs d2 in contact with both the male and female parts ofthe clutch, lpropose to employ springs, which may be of spiral form, coiled in the contracted ends of the spaces formed by the eccentric arched-shaped surfaces. Vhen the drum b is rotated bya pull of thestrap S, these dogs d2 are crowded into the narrower or contracted ends of the spaces between the female part d of the clutch and the eccentric arched- H designates a post, pivoted to thebottom IOO ,-2 essere of the forward end of the body or reach Adand` provided with downwardly-depending arms h h,having sleeves j jsupporting a dead-axle, a, to which the steering-wheel cis fixed. p p designate pedals or foot-rests secured to lugs Z and Z', extending from the arms h and h', respectively. KThe pressure of the operators foot on one of the pedals p or p turns the steering-wheel in the opposite direction, and thus the velocipede can b e guided at the will of the operator. At the saine time the pedals- 1o p serve as braces for the feet, facilitating the backward movement on the seat D and pull on the strap S, by means of which motion is imparted to the axle a and driving-wheels B B. Instead of a sliding seat, D, a stationary seat may be employed, if desired, although the sliding seat is. preferred.

It is obvious that instead of a single steering-wheel, C, two forward wheels may be employed for this purpose, thus increasing the steadinessof the velocipede and lessening the liability of accidents. It is also obvious that with slight modifications the driving-wheels and propelling mechanism may be set at the forward end and the steering wheel or wheels at the rear of the body or reach, if desired. I also propose to. employ abrake connected to the clutch, of the kind commonly used on friction-drums-for instance, with a connectingrod extending therefrom to a lever or crankarmv Within convenient reach of the operator, to enable the operator to stop the velocipede suddenly when necessary.`

pleasure, and a convenient means of conveyance from place to place.

What I claim as my invention, and desire to secure by Letters Patent, is-

'Ihe combination, in a velocipede substantially such as described,`of a drum, b, fixed to a hub, c, supported on an axle,a, and adapted to rotate independently of said axle, a strap, S, wound on said drum and having its free ends attached to a cross-bar, E, and a clutch having its male part d iixedly attached to said drum, and its female part cl fixed to said axle, with a convolute spring, G, spirally coiled around the hub of 'said drum and bearing against the body or reach A, whereby, when the drum is rotated under an impulse from the strap, motionis transmitted to the axle,and

v when the drum is rotated in reverse direction under an impulse from the spring the strapis rewound without retrograde motion of the axle, as set forth.

In testimony whereof I' have hereunto set my hand this 16th day of December, A. D. 1882.
