TWO-WHEELED VEHICLE.

SPECIFICATION forming part of Letters Patent No. 279,080, dated June 5, 1883,

Application filed April 25, 1883.

To all whom, it may concern Be it known that we, DAVID E. CHANDLER and JAY O. WILLIAMS, citizens of the United States, residing at Aurora, in the county of Kane and State of Illinois, have invented new and useful Improvements in Two Wheeled Vehicles, of which the following is a specification.

Our invention relates to two-wheeled vehicles of the class generally known as roadcarts, dog-carts, and sulkies.

The objects of our improvements are, first, to obtain a construction of twowheeled vehicle in which the body is so supported and braced by side springs fastened only thereto and to the axle independent of the draft-frame as to have only avcrtical movement, and thereby avoid the unpleasant motion accompanying two-wheeled vehicles; second, to obtain such a construction and arrangement of springs as will cause them to draw lengthwise and prevent the tipping down or tilting of the body, which usuallytakes place as the rider steps into the front of the vehicle and before sitting down; third, to center the pressure directly over the axle without regard to the part of the body on which the weight presses, thereby to avoid the backward and forward wringing and twisting of the axle by the springs, which would otherwise take place unless prevented by the old method of fastening the front part of the body to the cross-bar of the draft-frame; and, fourth, to render the body capable of being hung high or low, as may be desired. The construction, combination, and arrangement of parts whereby we effect our said objects are r \hereinafter described and claimed with reference to the accompanying drawings, in which- Figure l is a view in perspective, showing the application of our improvements to a twowheeled vehicle; Fig. 2, avertical longitudinal section taken through the axle, cross-bars, and whiffietree, showing the fastening of the spring on one side; and Fig. 3, a front view, the thills being cut back of the cross-bars.

The thills AA are secured to the axle B and braced by the irons C C, and have two crossbars, D D, the formerstraight and'the latter curved, while the whiffletree E is secured in the usual manner. The style of body, F, shown in the drawings is the phaeton; but other suitable shapes may be used as well. The side springs, G G, are the common elliptic sort, with the upper half-quarters removed and modified, as will be presently described, their lower halves fastened to the axle by bolts or- .to a cross-bar, I, extending across the body under the seat.

From the above the construction will now have been thoroughly understood, and in carrying out the objects stated the springs act in combinationwith the rock-rod. The cranks of the rock-rod secured transversely under the front part of the body equalize the action of the springs under the load, so that they may move together. As the rock-rod rolls under the load when the rider steps in on the front the upper rear quarters of the springs draw forward and lift the lower rear quarters, and as the rider seats himself the springs go down together, forward and rcar'alike, or nearly so,

the crank-rod forming abrace to the springs in connection with the body, the front and back parts of the body moving up and down together.

In regulating the hanging of the cart-body high or low down the cranks areshortened or lengthened, as the case maybe, and the body placed farther forward or backward, respectively, because when the cranks are short the body should be brought forward to bring more pressure upon the cranks, and when the cranks are long they would have more leverage, and the bodyshould be placed farther back upon the springs to bring a proper pressure over the axle. The front end of the body being supported directly upon the transverse roclc rod attached to the springs, which in turn are attached to the axle and the back part of the body, the movement of the horse cannot affect the action of the springs.

The use of the three-quarter elliptic springs having their rear upper quarters fastened un der the scat, over the axle, causes the weight to center over the axle and avoids strain upon the clips on the axle. This is by reason of the l tion, with the body and axle, of three-quarter joints which connect the halves of the elliptics. elliptic side springs and a transverse cranked lVe clain1 1.
