2 Claims. 1;

This invention relates to mechanism for ad, justing the camberofknee action vehicle wheels and by which the knuckle may be deflected without damage to anyeofrthe parts.

This application is a continuation-in-part of my application Serial No. 50-3;l84,'filed -Septem ber 21, 1943, for Camber Adjusting Tool, now Patent No. 2,425,556 granted.jAugust;l2, 1947.

The present invention relates to such a mechanism which can be actuated from a convenient position away from the knee, .,ac.tion, whereiit is fully accessible, and which is, particularly-suitable for pQwer actuation,

For av complete understanding, of the mechanism, reference may be had'.,to,the accompanying drawingsin which Figure 1, is a fragmentary, perspective view showingthe mechanism embodyingthe invention in position-for operation. I

Figure 2'is a perspective view showing a modified mechanism.

Figure 3 is a sectional view to a larger scale on line 33 of Figure 1.

Figure 4 is an exploded perspective view showing a further modification.

Figures 5 and 6 are perspective views showing still further modifications.

In Figures 1 through 6 there is illustrated a camber adjusting mechanism wherein the bending of the knuckle support is accomplished by rocking a forked member which straddles the upper portion of the knuckle support A. Referring first to Figures 1 and 3, a fork I may be provided with a tubular or other type of handle 2 extending backwardly from the juncture between the branches of the fork and substantially parallel thereto, the branches of the fork presenting free extremities spaced substantially greater than the thickness of the knuckle support to engage on opposite sides thereof at positions spaced therealong which forms a rock shaft and near its outer end it may be secured to a rectangular yoke member 3 having an extension 4 journaled in a stand 5. An actuating bar 6 may be thrust through the yoke 3 and then turned so as to rock the shaft 2, causing the transverse jaws of the member I to so engage and apply pressure to the upper portion of the knuckle support that this knuckle support may be deflected from the solid line position shown in Figure 3 to the dotted line position in which the desired adjustment has been effected. Where but a single pair of bending elements, such as the branches of the fork I which is twisted thereagainst, is employed, there is an unbalanced force tending to rock the axial member laterally of the vehicles Consequently, injFigure 1; means is,shown,'for' takingathe thrust pressure exerted, on they upper; portion; ,of, the knuckle pport at a no. inju y 1 to other parts of. the mechanism may. result,., In many; cases, however, no such thrust-takings means may be found-necessary, This, thrusts.

floor or ground.

In Figure 2 a modification is shown in which the shaft 2 is provided with a laterally extended arm I8 against which bears one end of a hydraulic power cylinder I 9, the other end of which engages a yoke hooked under the arm I6 of the lower fork l0, both forks having trunnions journaled in a common stand 511. Admission of pressure to the cylinder I9 will act to rock the shaft 2 counterclockwise.

In Figures 4 and 5 arrangements of mechanism similar to that shown in Figure 1 are illustrated, but wherein the camber adjusting force is exerted by hydraulic mechanism as in Figure 2. Referring to Figure 4, the upper fork member 20 is provided at its rear end with a journal 2| which may engage in a selected one of a plurality of journal openings 22 at the upper end of a strip 23, the journal 2| extending through a vertical slot 24 in a stand 25 supported on the floor or ground. A second forked member 26 corresponding to the forked member ID shown in Figure 1, is provided with an outer journal 2! which also extends through the slot 24 and is journaled in any one of the journal openings 28 at the lowen end of the strip 23. The forked members 20 and 26 are provided with lateral arms 30 and 3|, respectively, and means are provided by which these fork members are rocked in opposite directions to produce the camber adjustment.

In Figure 4 an arrangement is shown by which the upper fork member 20 is turned counterclockwise viewed from its outer end and the lower member 26 is turned clockwise. For this purpose a hydraulic cylinder 32 having its piston Icarriedthereby, and resting in iai. notc h ,l 2 in theuppen pqrtionrof astandIEi-i The fork Ifljisprovidedfwithaulaterali extension I6 through which may be passedvan;

bearing against the under face of the arm 3| is supported by a loop member 33 which passes over the outer end of the arm 30. When the hydraulic mechanism 32 is expanded, the arm 34 is forced upwardly and the loop 33 is lowered, forcing the arm 30 downwardly. Thus the desired relative rocking action of the two forks is accomplished.

In Figure 5 an arrangement is shown by which the upper fork member is rocked clockwise and the lower forked member rocked counterclockwise. In this arrangement the hydraulic cylinder mechanism 31 is arranged directly between the upper arm 30 and the lower arm 3| so that when it is expanded the upper arm is rocked upwardly and the lower arm rocked downwardly. It should be understood, however, that this motion is relative. Commonly the upper arm would have the larger motion because the camber adjustment takes place in the upper-portion of the knuckle support.

In Figure 6 a modification is shown in which the shank portions 40 of a pair of forks 4|, the outer ends of which are journaled in a link 42, are provided with arms 43 between the outer ends of which is carried a hydraulic cylinder 44. The forked inner end portions are spaced apart to engage against lengthwise spaced portions of the knee action support of the knuckle. Separation of the outer ends of the arms 43 by the introduction of pressure into the cylinder 44 will act to twist the forks 4| in opposite directions and thus produce the desired bending action on the knuckle support which is engaged between these forks.

From the foregoing description of certain embodiments of this invention, it should be evident to those skilled in the art that various other changes and modifications might be made without departing from the spirit or scope of this invention.

I claim:

1. A mechanism of the class described, comprising a pair of elongated members each having a forked extremity, the branches of the fork extending substantially parallel to the length of its member and spaced to straddle the knuckle support of a knee action mechanism, the pair of members being spaced lengthwise of said support, and means for turning said members relatively about axes lengthwise thereof in opposite directions.

2. A mechanism of the class described, comprising a pair of elongated members each ,having a forked extremity, the branches of the fork extending substantially parallel to the lengtli of its member and spaced to straddle the knuckle support of a knee action mechanism, an arm secured to each of said members spaced from said forks, and means engaging said arms for turning said members relatively about their respective lengthwise axes in opposite directions.
