JOSEPH PULLEN, OF CHICAGO, ILLINOIS.

VELOCIPED E.

SPECIFICATION forming part of Letters Patent No. 236,454, dated January 11, 1881.

Application filed September 4, 1880. (No model.)

To all 'whom it may concern:

Be it known that I, JOSEPH PULLEN, of Chicago, county of Cook, and State of Illinois,

, have invented a new and useful Improvement in Velocipedes, of which theibllowingis aspecication, reference being` had to the aecompanying drawings, illustrating the improvement, in which- Figure l is a central sectional elevation of a relocipede embodying my improvement, taken on line x, Fig. 2; Fig. 2, a plan or top view of the improved velocipede.

The nature of the presentinvention consists in mechanism to rotate the drive-wheels ot' a four-wheeled velocipede. A rear and forward bar are attached to the frame of the device, and to the rear bar are hung two levers, to the lower ends of which are jointed two 'conmeeting-rods. The forward ends otl the connecting-rods are pivoted to the levers which are actuated to put the devicein motion. The actuating-levers are hung to the forward bar mentioned, and the rear levers connect with crank-wheels, which put in motion two main Willey-wheels, and the pulley-wheels put the drive-wheels of the velocipedein motion, as is hereinafter described and shown.

A A shows the main frame of the device, which is constructed, for convenience, in the form shown, land E lt are the brackets which support the shafts S, to each of which are attached thecrank-wheelsJ J and drive-pulleys I I. A rear bar, B, is attached to the top of the main frame, and to it are hung two levers, L, so that they may have an oscillating movement. Two connecting-rods, M, are respectively jointed to the lower ends of the levers L, and their forward ends are jointed to the lower ends of the actuating-levers N N, which are hung to the forward bar, C, to oscillate. Connecting-rods H H are respectively pivoted to the upper ends` of the levers L, and are jointed to crank-wheels J by means ot ordinary wrists. This construction is such that when the levers N N are alternately brought backward and forward the drive-pulleys I I will putin motion, by means of link-belts P P, the pulleys K K, which are attached to the hubs of the wheelsF F.

rIhe levers N N may be operated either by hand or foot; but it operated by the foot footseats must be attached to them in the ordinary manner.

The forward truck,T Gr, is pivoted to the forward part, A', of the frame in the ordinary manner, and is guided or steered by a Wheel, V, chain W, and wheel Y. The wheel V is attached to a standard, Z, which is ixed to rotate in the bar C, and the wheell Y is fixed to the standard l of the trucks.

The lever a is grasped by the hand to turn the wheel V in the ordinary manner of steering like devices.

In practice the truck-wheel G should be of such diameter as to come below the chain W, that the device may make short turns.

I claim and desire to secure by Letters Patent- The combination of the bars B C, levers L N, connecting-rods M H, crank-Wheels J J, pulleys I K, and chains P, for giving' motion to the velocipede, as specified.

JOSEPH PULLEN.
