RUNNING-G EAR FOR VEHIQLES.

SPECIFICATION forming part of Letters Patent No. 660,327, dated October 23, 1900-.

Application filed December 9, 1899. Serial No. 739,794. (No model.)

To aZZ whom it may concern.-

Be it known that I, FRANKLIN COPELAND, a citizen of the United States, residing at New York, in the county and State of New York, have invented certain new and useful Improvements in Running-Gear for Vehicles, of which the following is a full, clear, and exact description, such as will enable those skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in running gear for vehicles of that class which are used for light driving.

It has for its object the provision of an axle having a high arch to permit a close hitch without interfering with the movement of the horse and at the same time allows the use of very low wheels of the pneumatic type.

It also has for its object the provision of a spring mechanism forhanging the body to the axle so that the body will be carried at a normal elevation, In the vehicles heretofore constructed with very high arched axles the body has been carried too high by the springs; and, further, it has for its object the provision of a coupling mechanism for reducing the vibration of the arched'axles. The high arched axles in ordinary use, in the case of the front axles more particularly, are coupled to the body at the tops of their crowns. Owing to the legs of the axles extending to a considerable distance below their coupling-points, there is considerable vibration; and, further more, it has for its object the provision of a.

mechanism adapted to take the place of the ordinary side-bar and which at the same time will not interfere in any way with the turning of the wheels.

The invention consists in the novel construction, combination, and arrangement of parts, such as will be hereinafter fully described, pointed out in the appended claims, andillustratedintheaccompanyingdrawings.

In the accompanying drawings, in which similar letters of reference designate corresponding parts, Figure 1 is a side elevation of a running-gear embodying the invention with a vehicle-body mounted thereon. 2 is a front elevation of the same. Fig. 3 is a plan view of the running-gear. Fig. 4 is a support B, carrying the bar B.

Fig. 9 is a side elevation of a modified form of the running-gear with a vehicle-body mounted .13 is a sectional view on the line l3 13 of Fig.

10. Figs. l4, l5, and 16 are detail views showing the several parts of thelower fifth-wheel mechanism in the modified form. Fig. 17 is a perspective view showing the modified form of the running-gear. Fig. 18 is a similar view showing the preferred form of the runninggear.

The preferred form of the invention is shown in Figs. 1 to 8, inclusive, and Fig. 18. This construction will be described first.

The vehicle-body carried by the runninggear may be of any construction suitable in the premises. Both axles of the runninggear have substantially the same construction, so a description of one will suffice for both. The front axle, for example, is arched and consists of the crown A, the rises A', and the spindles A The crown and the rises are connected by the curved elbows A These several parts may be made integrally or made separately and suitably joined. This construction of the axle gives it a symmetrical appearance and at the same time adapts it to sustain considerable weight. It also adapts the axle to the comparatively low wheels ordinarily used on such vehicles.

On each end of the crown A is securedthe Each bar is braced by the rods B connecting its ends with the rise A (See Fig. 5.) These bars to a considerable extent serve the same purpose as the ordinary side-bars. Practically the two bars 8 on the same side of the running-gear act as a single bar; but by having two of them, each extending but a short distance, rather than a single one extending the entire distance a much shorter turn of the vehicle can be secured, as thefront wheels can be turned farther under the body of the Vehicle without cramping. Compensating springs B are attached at their ends to the bars B. Neartheirends, as at E the springs bend slightly below their points of attachment to the bars. At their middle portions, as at B they project above the crown of the axle. These springs-a pair to each axlecarry an end of the vehicle-body. WVhen depressed, they drop below the crown of the axle, one on each sideof the latter, and are limited in their downward movement only by their resiliency and the body contacting with the supports B.

So far the description of the front axle is applicable to the rear one. The other features of the front axle will now be described.

On the tops of the springs B are secured the bolsters O, to which is secured the fifthwheel 0, provided with the radial cross-pieces 0 In the jointure of the cross-pieces is the aperture 0 To the under side of the bottom of the body are secured the wear-plates O (see Fig. 4,) on which the fifth-wheel turns.

To hold the fifth-wheel in its proper position on the wear-plates, the latter are provided with projections. 0 which extend beneath the fifth-wheel. A bolt 0 passes through the bottom of the vehicle-body and the aperature C of the radial cross-pieces and pivots the axle and the body together. A nut C is provided for holding the bolt in place against accidental displacement.

To the crown of the front axle is secured the ant segment D immediately below the fifth-H fieel C and concentric with the latter. This segment is adapted to move on a second annular segment D, mounted on the forward end of the perches D To hold the two segments together, a collar D is secured to the segment D, and through it the segment D moves. (SeeFigs. 7 and 8.) To the extreme forward ends of the perches D is attached the hub D A bolt D passes through the crown of the axle immediately below the bolt 0, and the hub D and the axle and perches are thereby pivoted together.

By means of the foregoing construction a double fifthwvheel mechanism is provided, whereby the vibration of the front axle is minimized. Where there is but a single fifthwheel mechanism or single pivotal point between the axle and the running-gear, the axle oscillates vertically about the pivotal point. This is especially so in thisclass of vehicles, where the axles have high arches and low wheels. By providing the double fifth-wheel mechanism or double pivotal point one above the other the liability of the axle to oscillate or to vibrate vertically is very much lessened.

To each of the rises of the front axle is secured a foot-rest E to facilitate the gettingin and out of the vehicle.

The springs B mounted on the rear axle, are secured to the under side of the body in the usual manner. While the two axles have the same dimensions, yet the crown of the rear axle is nearer the under side of the botthe crown.

the two together. i to the under side of the members G of the crown of the front axle by the screws J passrom of the body than the crown of the front axle, and consequently higher above the ground. This is owing to there being no fifthwheel mechanism interposed between the rear axle and the body. As the rear axle is higher, the customary higher rear wheels can be used. To adapt them to the difierence in height between the two axles and at the same time be parallel with the body, the perches D have drops D at their rear ends. The perches are braced by the rods D connecting them with the rises of the rear axle.

In the modification shown in Figs. 9 to 17, inclusive, the construction is substantially thesameasthathereinbeforedescribed; The principal difference is that in the modification the axle is bifurcated. In the modified form the axle consists of the crown F, the rises F, and the spindles F These several parts are connected by the elbows F The crown, rises, and curved elbows are bifurcated and consist of the two members G. In the crown the two members are a considerable distance apart and are substantially parallel. In the rises, however, the two members gradually approach each otherand come together, as at G. At each end of the crown on each member is secured the support G A bar G is mounted at its ends in the supports G at each end of (See Fig. 12.) This bar extends from one member G to the other and is above the crown. The springs G are attached at their ends to the bars G between the members G, and when. depressed they drop between the said members. 011 the tops of the springs G carried by the front axle, are secured the bolsters lI. On the latter is mounted the fifth-wheel H and adapted to turn against the wear-plates Hf, secured to the under side of the body. (See Fig. 13.) These plates have lugs H engaging with the fifthwheel to hold the latter in place. A bolt H" passes through the bottom of the body and the cross-bar H of the fifth-wheel and pivots A fifth-wheelJ is secured ing through the flanges J into said members, and it is provided with a cross'piece J This fifth-wheel turns on the annular plate J secured to the perches J by the screws J. The annular plate has a cross-piece J A hub J is attached to the ends of the perches. A bolt J 9 passes through the cross-pieces of the fifth-wheel and the annular plate and through the hub and pivots them together.

.The fifth-wheel and the annular plate are held together by the clips J carried by the fifth-wheel and projecting under the annular plate. It is to be observed that the bolt J is immediately below the bolt 11 and that both fifth-wheel mechanisms are parallel, and thereby the same results are obtained as in the first instance. Between the rises F of the front axle are secured the rods K, can rying the steps K. The springs G of the rear axle are secured to the under side of the bottom of the body of the vehicle in the usual manner. The perches J have the drops J and the braces K Other modifications of the invention are apparent. For instance, the axles are well adapted to be used in the construction of two-wheeled vehicles.
