SPECIFICATION forming part of Letters Patent No. 451,029, dated April 28, 1891.

Application filed August 23, 1890. Serial No. 362,851. (No model.) I

To aZZ whom it may concern.-

Be it known that I, GEORGE M. COX, a citizen of the United States, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Two lVheeled Vehicles; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in two-wheeled vehicles; and the objects of my invention are, first, to provide a means to obviate all jerking movement caused by the motion of the horse, which is termed horse motion, second, to provide a twowheeled vehicle that will be as easy in motion as a four-wheeled vehicle; third, to obviate the necessity of using a suspension-strap for the front of body, at the same time to be durable and cheap in construction. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure l is a vertical side view of a twowheeled vehicle, showing the general construction of my invention. Fig. 2 is an end view of same, showing the construction of half-spring and flexible connections. Fig. 3 is an enlarged view of one of the flexible connections, showing its general construction.

Fig. 4 is a front view of same.

Similarlettersreferto similar parts thro ughout the several views.

In the accompanying drawings A indicates a single axle, upon which is mounted the elliptical springs B and B. Said springs are secured to the axle by means of clips.

Secured upon the upper arch of the elliptic springs B and B are the standards 0 and O. The said standards are secured in position upon the springs B by clips D. The standards are constructed with a hole in the upper end to receive the clevis E, which is secured rigid in the standard 0, or may form part of said standard.

F indicates a half-elliptic spring, which is secured to the under side of the body G by any suitable mechanism, and centrally with the axle. This spring is constructed with a slotin each end to receive the knuckle-joint I-I, forming part of the connnection between the springs B and half-spring F. The stand ard O is also provided with the knuckle-joint H. I and I indicate metallic plates or bars,

H and H by the bolts or rivets J. These connections are to allow the body to reciprocate in any direction. K also indicates a universal connection, which is constructed similar to the connectiondescribed. These connections, however, at their upper ends are connected to the side springs by a clevis, which forms the bolt connecting the two halves of the side springs. The upper end of the connection K is pivoted within the clevis L, the lower end being pivoted to the plate M secured to the under side of the body, as shown in Figs land 2. Figs. 3 and 4c show the construction of the connections. Itwill be readily seen that each of the connections having knuckle-joints at the top and bottom, and the upper ends being attached to the side springs, the lower ends connected to the half-spring and the body, allows a reciprocatory movement to the body and obviating all jerk motion common in all twowheeled vehicles.

Two half-springs may be used in the place of the one shown under the seat, one on each side of the vertical center of the axle, with double connections, which would obviate the necessity of using a metallic connection in the front. A flexible connection may be used there.

' Having fully described myi'fivention, what I claim as new, and desire to secure by Letters Patent, is

1. In a two-wheeled vehicle, the combination of the axle, the springs mounted thereon, the body, the half-spring having the pintles, the knuckles on the pintles forming joints, the knuckle-joints connected to the springs, and the bars or plates connected to the joints, substantially as described.

2. In a two-wheeled vehicle, the combination, with the axle, shafts, and body, of a brace-rod connecting the tops of the side springs, a half spring or springs secured upon the under side of the body, universal connections from the half-springs to the center of the side springs, and universal connections from which are pivoted to the knuckle-joints the front end of the side springs to the body,

arranged as shown, and for the purpose specified.

3. In a two-Wheeled vehicle, the combination of the axle, springs, and body, the halfspring secured to the body, the connections between the half-spring and elliptical springs, and the connection between the front end of the body and front end of the springs, substantially as shown.

ln testimony whereof Ialfix my sign atu re in the presence of two Witnesses.
