IMPROVEMENT IN WH EEL.VEHICL..S.

Specification forming part of Letters Patent No. 35,017, dated April 722i, i802.

Figure l is a plan or top view of the run I ning-gear of a wheel-vehicle with my imtion of the same, taken in thelinefr, Fig. l.

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

This invention relates to an improvement in the manner of attaching the front axle of the vehicle to the perch or to iixtures ecnnected to the body, as hereinafterfully shown and described, whereby the vehicle may be turned within a small compass, .the front wheels admitting of being so cramped or turned as to insure the result stated and still allow a requisite space between the front and back wheels for the attachment of proper steps to the body of the vehicle, and also admit of the front and back wheels being placed nearer together than usual without coming in contact when the frontwheels are turned or cramped.

To enable those skilled in the art to fully understand and construct my in veution,l will proceed to describe it.

A represents the back axle of a wheel-vehicle, and B the reach or perch, which attached atits back end to the back axle, A, and at its front end to a bolster, C, as shown in Fig. l. The bolster C has two lugs or projections, o a, extending from its front side at right angles, one near each end, and in these lugs or projection the ends of a shaft, D, are secured. The shaft D is at right angles with the perch B, and on said shaft there is placed a slide, E, provided with a pendent pintle, b, which passes loosely through the front parts of two eyes, c c', and has a head, d, on its lower end, as shown in Figs. 2 and 3. The

eye c is attached to the front axle, F, at its center, and the eye c is in the front part of a bar, d', which is secured transversely to the under side of the front axle, F, and has its back end fitted loosely on a pintle, e, attached to. the under side of a slide, G, on a shaft, Il, which is parallel with the perch B, and has its ends secured in pendants f f of the perch. (See Fig. 3.) The upper end of the slide G is connected by a pivot, dx, with a semicircular plate, I, which is attached to the upper surface of the front axle, F. (See Fig. l.) The front axle has thills or a draftfpole attached to it in the usual or in any proper way.

From the above description it will be seen that when the `vehicle is drawn along, the pull will be on the slide E and shaft D,

g the pintle b forming the connection between provement applied to it; Fig. 2, a front view of a portion of the same; Fig. 3, a vertical secthe front axle, F, andthe slide E, and it will also be seen that when the front axle, F, is turned the slide E will move on the shaft D either to the right or left, while the slide G will move forward on its shaft ll. This movement of the slides It G, as indicated in red in Fig. l, produces a very importa-nt result. It causes the front axle, F, to turn from a back center, which is the pivot ax, that connects the semicircular plate I with the slide G, and it also causes said center ax to move forward while the' axle F is turning.

vConsequently a quick cramping position of the front axle is obtained from a back center, while the disadvantage hitherto attending a fixed back center-to wit, the bringing ol the front wheels suddenly in contact with the body of the vehicle-is avoided; and hence by my invention the front and back wheels may be placed nearer together than usual, where a fixed back center is used, without the front wheels comin in contact with the back wheels or with the body of the vehicle, and all necessary steps maybe attached to the vehicle without the front wheels coming in contact with them.

I do not claim attaching the front axle of a vehicle to its perch or reach by Ia back center, or, in other words, bya king-bolt placed back of the axle, in order to obtain aquick cramping or turning movement of said axle, for this ha-s been previously done; but

.I do claim as new and desire to secure b v Letters Paten t The connecting of the front axle, F, to the perch or reach B by means of the two slides E G, placed, respectively, on the shafts D II, and connected with the axle F, substantially as shown, for the purpose herein set forth.
