Application filed June 29, 1911. Serial No. 636,073.

To all whom it may concern Be it known that 1, James W. DREW, citizen of the United States, residing at Brackettville, in the county of Kinney and State of Texas, have invented certain new and useful Improvements in Vehicles, of which the following is a specification.

This invention relates to improvements in wheel-vehicle structures, and more particularly to vehicles employed for farm, road, country or city vehicles.

The objects of the improvements are first, to combine light weight,-strength, durability, ease of propulsion and steering with independent pivot axles and a twinrcach gearing system; obviating and eliminating the unpleasant jerking and shaking of the team, driver and passengers caused by the ungovernable front wheels of the common vehicle which gives way when encountering ohstruo tions that are more or less lying in the way. Second, to obviate the weak, dangerous, and much dreaded tendency of the common vehicle to upset when turning from a side hill position to go up the hill, as hereafter explained. I attain these objects by the mechanism illustrated in the accompanying drawing, forming a part of this specification, in which Figure 1 represents a plan view of my invention with the wheels and the head portion of the bolster removed. Fig. 2 is a front elevation of one of the members of the two-part roller device. Fig. 3 is a perspective view of one of the coupling devices between the reach and the lower bolster members. Fig. 4 is a plan view enlarged of one of the bolsters together with the swiveled axles attached. Fig. 5 is a. front elevation of the parts shown in Fig. .1-, except the swiveled axles. two part T bolster detached.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawingby the same reference characters.

The improved device embraces in general a supporting frame comprising two two part bolster devices located where the ordinary axles of an ordinary vehicle are located, the forward bolster device having short swiveled axles at its ends adapted to carry bearing wheels and the rear bolster carrying similar swiveled axles likewise adapted to support bearing wheels. The forward and rear bolster devices are substantially alike and the description of one will Fig. 6 is an end view of the.

suffice for both. The bolster devices each comprises a lower member 10 and an upper member 11, bolted or otherwise suitably secured together. Each lower bolster member is provided near one end with a recess 12 in which a bearing member 13 is supported, one of the bearing members being shown in perspective in Fig. 3 and is formed with recesses in its ends to engage against the sides of the bolster member 10 and with a central recess to receive a stationary reach-member 14:. The reach-member 14K is bolted as represented at 15 to the bearing member 13, and thus rigidly couples the two bolster devices at one side of the center of the running gear, as shown in Fig. 1. Formed in each of the bolster-members 10 near the other end is a recess 16 somewhat longer than the recess 12 and in which a bearing member 17 is mounted for a slight endwise movement, the me1nber 17 being substantially the same as the member 13, as shown in Fig. 1. A. movable reach-member 18 extends through the intermediate recess of the bearing members 17 and is pivotally united therein by bolts 19. The intermediate recesses of the bearing members 17 are slightly wider than the reach so that the necessary play or move ment is permitted when the reach-member 18 is actuated as hereafter explained.

The bolster-members 10 are coupled by diagonal braces 20, and connected at. 21 to the reach-member 14'. is a fulcrum bar 22 which extends over the reach-member 18 and is connected thereto by a pivot bolt 23. The fulcriun member 92 is bolted at 9. 1 to the braces 20 at their crossing points. By this means the fulcrum 22 rigidly supported in position and serves as a central support for the reach-member 18 so that when the former is actuated. it is caused to swing upon the pivot By this means when the forward end of the reach-member 18 is moved away from the stationary reach-1ne1nber 14]; the latter will be moved toward the rear end of the reach-member 141-, and this movement reversed when the forward end of the reachmember 18 is moved toward the stationary reach-member 14, as will, be obvious. The members 1'7 are thus caused to slide within the recesses in the bolster members 10 and are retained in position by the recesses at their ends which bear upon opposite sides of the lower bolster member.

At its forward end the stationary reachmember 14 is provided with a strap 25 which extends over the upper and lower faces of the reach and forms a bearing for a collar-like device 26, the collar having preferably square flanges 27 at its ends and bearing upon the opposite side faces of the straps. A strap 28 which is substantially a duplicate of the strap is connected to the opposite faces of the movable reach mem ber 18 and forms a bearing for a collar 29 having bearing flanges 30 and is a substantial duplicate of the collar member 26 with its flanges 27.

Extending inwardly from the collar 26 is a half roll-er member 31, while a similar half roller member 32' extends inwardly from the collar 29. The members 3132 bear against each other face to face their whole length as shown in Fig. 1. At its center the half roller member 31 is enlarged as shown at 33 with a transverse mortised openingformed through the enlargement, while a similar enlargement is formed upon the roller member 32 and is provided with a similar mortise, the two mortises designed to receive the inner end of the tongue repre sented' at A pivot pin 36 extends through the enlargement 33 and its mortise and likewise through the tongue 35, while a similar pin 37 extends through the en largement 3d and likewise through the tongue 35. By this means the tongue is coupled to the roller members and when the tongue is moved laterally by the team theroller members will be shifted longitudinally as will be obvious. The collar 26 is provided with a transverse aperture indicated at 38 and designed to receive the outer end of the collar member 32, while a similar aperture 39' is formed. in the collar 29 toreceive the outer end of the roller member 31. The roller members are thus guided in their movement when the tongue is moved laterally for cramping the vehicle. This movement of the tongue it will be obvious causes the movable reach-member 18 to swing upon its pivot 23, the object to be hereafter more fully explained. A swiveled axle is connected to each end of each of the bolster members 10, one for each of the bearing wheels, and as these axle devices are precisely alike, the description of one will sufiice for all. The swiveled axles are represented at 40 and are formed with anenlargement 41 at the inner ends extending vertically, each enlargement being provided with an arm 42 at its ends which bear upon the upper and lower faces of the bolster member 10, and extending downwardly through the bolster members 10 and 11 and the arms 42 is a pivot bolt 13. By this means the axles are mounted to swing laterally upon the bolsters and firmly support-- ed relative thereto.

Each of the upper head members ii is provided with a lateral projection Get, and

coupling the members 64: of the rearward axles is a rod 65, while a similar rod 66 couples the projections 64 of the forward pivoted axles. Connected to the projection 6-15 next to the movable reach member 18 is a rod 67, while a similar shorter rod 68 is connected to the arm 6 1 of the forward swivel axle next tothe movable reach-member 18. The rods 6768 are pivotally united 'at their inner ends, as shown at 69"70 to the movable reach-member 18.. By this arrangement it will be obvious that as the reach-member 18 is moved upon its pivot 23, as before described, the pivot axles will be swungcorrespondingly tocause the wheels to cramp as will be obviousl/Vhat I claim as new is 1.
