VEHICLE RUNNING-GEAR.

SPECIFICATION forming part of Letters Patent No. 723,519, dated March 24, 1903.

Application iiled January 12, 1903. Serial No. 138,702. (No model.)

To all whom it may concern:

Be it known that I, EMORY L. FAERIs, a citizen of the United States, residingat London, in the county of Laurel and State of Keutucky, have invented a new and useful Vehi.

cle Running-Gear, of which the following is a specification.

This invention relates to vehicle runninggears, and has for its objects to produce a de- Io vice of this character which will be simple of construction, comparatively inexpensive to manufacture, efficient in operation, and one in which the rear axle and reach-beam will control the lateral movements of the vehicler 5 body and the front axle have a swinging movement in a vertical plane independently of the movements of said parts, thus obviating all twisting or otherwise straining of the fifth-wheel. zo The invention comprises the details of construction and combination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a top plan view of the improved running-gear. 5 .z 5 Fig. 2 is a longitudinal sectional elevation o f the same. Fig. 3 is a front elevation illustrating the independent swinging movements of the axles. Y

Referring to the drawings, 1 indicates the 3o rear axle, and 2 the front axle. These parts may be of any suitable material and of the usual or any desired construction with the exception of the changes, hereinafter pointed out, necessary in applying the present invention thereto.

4 indicates the reach-beam, preferably tubular in cross-section and having its rear end bifurcated, the bifurcated portion being bent at right angles to the reach-beam to form 4o horizontal arms 5, which are attached by bolts or other suitable means to the rear axle. This reach-beam extends longitudinally of the vehicle-body and has its front end mounted in a collar 6, formed on the lower face of the front spring-rest 7 and secured in place thereon by means of a vertical bolt 8, which secures the spring-rest iixedly to the reachbeam and insures the spring-rest and rear axle having the same swinging or rocking 5o movement laterally, due to the rear wheels traveling over uneven ground, and imparting such movement to the vehicle-body, which is sustained, respectively, at its front and rear ends by the said spring-rest and rear axle.

9 indicates ahollow sleeve or casing mount- 55 ed upon the front end of the reach-beam and adapted to rotate freely with -relation thereto. This casing is provided near its front end with a vertical recess 10, into which the projection on the lower face of the 'front spriug- 6o rest 7 projects to be received and carried by the front end of the rear beam.

10cb is the vertical king-bolt, which in accordance with the present invention is carried by and depends vertically from the casing 9. This king-bolt may either be formed integral with the casing, as herein shown, or have its upper end threaded and screwed into the lower face of the casing. The front axle 2 is provided with a rearwardly-extending 7c horizontal semicircular protuberance 11, provided with a vertical hole for the reception of the king-bolt and by which the`front axle and casing 9 are connected together. The protuberance 11 may be formed integral with 75 the axle or may be a separate part secured thereto by bolts or otherwise and is susceptible of swinging freely upon the king-bolt to permit the axle to turn in a horizontal plane for guidi-ng the vehicle in the usual 8o manner.

12 indicates a brace member in the form of a metal plate screwed at its front end onto the lower end of the king-bolt and projecting rearwardly and upwardly and connected at its rear end to the casing 9 by means of a suitable bolt 13.

14 indicates a spring-plate or the like pivoted to the brace member and having its free end recessed to form arms which lie at op--go posite sides of the head of the bolt 13 to prevent the same becoming loosened. The brace member serves the double function of strengthening the parts and preventing the escape of the front axle from the king-bolt.

From the foregoing it will be seen that owing to the reachbeam being free to rotate in the casing andhaving the frontspring-scat or head iixed thereto the rear axle may swing or rock freely in a vertical plane to accommodate the rear axle to any irregularities of the ground encountered by the rear wheels and that the Vehicle-body will move entirely with these parts, While at the same time the front axle will have an independent rocking or swinging movement to accommodate the same to any irregularities which may be encountered by the front wheel. Consequently the rear axle may tip upward from left to right, as shown in Fig. 3, at the same time that the front axle tips upward from right to left Without injuriously twisting or straining the parts in the slightest degree.

Having thus described my invention, what I claim is- In a Vehicle running-gear, the combination with the rear axle, of a reach-beam connected therewith, a tubular casing mounted on the EMORY L. FARRIS.
