RUNNING-GEAR FOR VEHICLES.

Specification of Letters Patent.

Patented. NOV. 21, 1905.

To all whom, it may concern:

Be it known that we, VAN BUREN MARTIN and THOMAS RILEY STEWART, citizens of the United States, residing at Hopkinsville, in the county of Christian and State of Kentucky, have invented a new and useful Running-Gear for Vehicles, of which the following is a specification.

This invention relates to running-gear for vehicles; and the invention has particular reference to what is generally known as a shortturning running-gear, among the objects being to simplify and to improve the constructilon and operation of running-gears of this 0 ass.

Another object of the invention is to provide a short-turning running-gear which is adjustable as to the length thereof, so that it shall be adapted for hauling various kinds of material, including poles, long lumber, and similar material which requires a comparatively long running-gear.

Other objects are to promote the simplicity, durability, and general efficiency of this class of devices.

WVith these and other ends in view, which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of embodiment of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that the right is reserved to anychanges, alterations, and modifications to which recourse may be had within the scope of the invention and without departing from the spirit or sacrificing the efiiciency of the same.

In said drawings, Figure 1 is a top plan view of a running-gear constructed in accordance with the principles of the invention. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a bottom plan view with dotted lines indicating the turning position of the running-gear. Fig. 4 is 'a sectional detail view taken on the line 4 4 in Figs. 1 and 2. Fig. 5 is a perspective detail view of the slide operating upon the reach. Fig. 6 is a perspective detail view of the end of one of the hounds having the slide-engaging member.

.Fig. 7 is a transverse sectional detail view taken on the plane indicated by the line 77 in Fig. 1.

Corresponding parts in the several figures are indicated throughout by similar characters of reference.

1 and 2 designate, respectively, the front and rear axles, each of which is provided with low wheels, (designated, respectively, 3 and A) it being understood that the present invention is applicable especially to low-down vehicles or trucks. The front and rear axles are connected by the reach or coupling-pole It, which is fitted between the sand-boards 5 6 and the axles l 2, said sand-boards being provided with recesses in their under sides, as shown at 7 in Fig. 4 of the drawings, for the accommodation of the reach. Supported upon the sand-boards are the front and rear bolsters 8 9, and the bolsters, the sand-boards, the axles, and the reach are connected with each other by means of king-bolts 1O 11, which permit the front and rear trucks to turn freely with relation to the reach. The latter is made of considerable length, and it is connected near its forward extremity with the front truck, while the rear truck is capable of longitudinal adjustment, a plurality of apertures, as 12, being provided for the reception of the kingbolt 11.

The reach A supports a casting 13, which constitutes a slide longitudinally movable upon the reach. The sides of said slide are provided with dovetailed grooves 14:, and the top of the slide has an aperture 15 for the reception of a bolt 16, whereby it may be secured in adjusted position upon the reach, which latteris provided with a plurality of apertures, as 17, for the reception of said bolt. The latter may also serve, when desired, to support in position a seat 18 for the driver, to be utilized when the running-gear is driven unloaded from one place to another. The rear end of the slide 13 is provided with a hook 19, which is connected adjustably, as by means of chains 20, with the rear bolster 9, the swinging movement of which will be thereby limited. The front bolster 8 is in like manner connected by chains 22 with a hook member 23 upon the reach. The bolsters may of course be left free to move upon their respective pivots or king-bolts, if desired; but it will be usually preferred to limit their respective movements in the manner described.

EM designates the tongue, and 25 the tonguehounds, which diverge rearwardly and are fitted and secured between the front axle and the sand-board 5, supported upon said front axle, the rear ends of said hounds being connected by an arch member 26, which operates as a fifth-wheel to support the front portion of the reach.

Pivoted between the rear axle and the sandboard 9 are the rear ends of the rear hounds 27, which converge in a forward direction and which are provided at their front ends with pivotallysupported heads 28, having dovetailed flanges 29, operating in the dovetailed grooves 14: of the slide 13. Said rear hounds are provided with clips or clamps 30 for the reception of the rear ends of bars or straps 31, the front ends of which are pivotally connected with the under side of the front axle, as clearly seen in Fig. 3 of the drawings, said straps or bars being extended rearwardly and across each other, the strap or bar connected with the right end of the front axle being connected at its rear end with the left hound 27, and vice versa. The connection between the bars 31 and the hounds 27 is adjustable, said bars being provided each with a plurality of apertures 32 for the reception of bolts, as 33, whereby said bars are connected with the clips or clamps upon the hounds 27.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of this invention will be readily understood by those skilled in the art to which it appertains. It will of course be understood that in order to effect adjustment of the rear axle with relation to the reach it is only necessary to remove the king-bolt 11, the slide-securing bolt 16, and the coupling pins or bolts 33. The axle may then be moved rearwardly upon the reach or forwardly, as the case may be, the slide and the hounds 27,- which latter are connected with the rear axle, be simultaneously adjusted to the desired point when the connecting bolts or pins are restored, and the runninggear will thus be coupled in position for operation. In all positions of the respective parts the rear hounds will be supported at their front ends by their pivoted heads engaging the dovetailed grooves in the slides 13. The said hounds being connected with the couplingbars 31 will operate in conjunction with the latter to transmit motion between the front and rear axles when a turn is made, thus permitting the running-gear to turn in an exceedingly-limited space. This is a great advantage under many circumstancesfor instance, when traveling upon narrow and crooked roads, when short turns are to be 'made through gates and other obstructions,

and under other like circumstances. In driving attention need only to be paid to the front truck. Where the latter passes, the rear truck must of necessity pass in the wake thereof.

This improved running-gear, as previously stated, is adapted to hauling of all kinds; but it is particularly well adapted for the purpose of transporting th reshing-machines and other heavy machinery. of a like nature, which it is frequently necessary to carry through gates and the like. It is to be understood, however, that the improved running-gear is of general application, that it may be used with or without a wagon box or bed, and that all changes of a mechanical character as to size, proportion, general assemblage of parts and the like are considered within the scope of the invention and are to be left open to the option of the manufacturer of the device.

Having thus described the invention, what is claimed is 1. In a running-gear of the class described, a front and a rear axle, a reach pivotally connected with said axles the rear axle being longitudinally adjustable upon said reach, a slide movable upon the latter and provided with dovetailed grooves, hound members connected pivotally with the rear axle and having pivoted heads provided with dovetailed flanges working in said grooves, and bars connected pivotally with the front axle, crossing each other, and connected adjustably with the rear hounds.

2. In a running-gear, a rear axle, a reach connected, pivotally and adjustably therewith, a slide upon said reach having dovetailed grooves in the side thereof, and hounds connected pivotally with the rear axle and having members engaging the dovetailed grooves in the slide.

3. In a running-gear, an axle, a reach connected pivotally and adjustably therewith, and hound members connected pivotally with the axle and longitudinally slidably with the reach.

4L. In a running-gear, an axle, a reach connected pivotally and adjustably therewith, hounds connected with the axle, and members connected pivotally with the hounds and having slidablegroove-and-tongue connection with the reach.

5. In a running-gear, an axle, a reach connected pivotally and adjustably. therewith, hounds connected with the axle, a sliding member mounted upon the reach and having dovetailed grooves, and members connected pivotally with the hounds and having tongues engaging said grooves.

6. In a running-gear of the class described, a front and a rear axle, a reach pivotally connected with said axles, hounds pivotally connected with the rear axle, a slide adjustable upon the reach and having dovetailed grooves in'the sides thereof, members connected with our own we have hereto afiixed our signatures in the presence of two witnesses.
