This invention relates to motor vehicles and is primarily directed to independent wheel suspension and adjustable camber.

The chief object of this invention is to provide a motor vehicle driving and/or steering wheel with a relatively independent mounting, whereby camber of the wheel may be readily adjusted and retained in adjusted position and the wheel wheel, permitting independent wheel action, that is, movement of each wheel independent of the other and the frame in an up'and down direction.

- The chief feature of the invention consists in the accomplishment of the foregoing objects.

A further feature of the invention consists in the application thereof to a lever arm type sup= ent of the other wheels'and which is associated with a spring carried by the frame.

The full nature of the invention will be understood from the accompanying drawings and the 'following description and claims:

The opposite end of the lever I2 is indicated at H and by means of a pair of links I! that are arranged about two end of atransverse spring IS. A single transverse 45 spring may extend across the frame or the same may consist of longitudinally aligned spring por tlons suitably secured to the frame and transverse to the longitudinal axis of the frame.

It is to be understood that while the frame has -50 been indicated by the numeral ID, the invention can be applied and associated with a combined frame and body in which the frame is not a distinct element, separate-and apart from the body.

ing wheel in trailing relation relative to the axis of the pivotal support of the lever upon the frame. The spindle for each front wheel is not illustrated in detail but is carriedby the usual king-pin construction and the king-pin in turn 5 issupported by the projecting portion IQ of the lever. Associated with the spindle is an arm 20 by which the. steering wheel is controlled for directional movement of the vehicle.

The supported portion ll of the lever arm is 10 suitably and adjustably carried by the frame, as illustrated clearly in Fig. 4, and to which reference will be had hereinafter when 'discussing camber.

The rearward wheels of the vehicle are indi- 15 catedlbythe numeral 2l and thelarms 22 trail- -ingly suppo t the driving wheels with respect to the axis of the pivotal support of the lever arm upon the frame. As beforementioned, the support for the lever arm is of adjustable character 20 and issimilar to that beforementioned with respect to the end of the forward arm l2 and is more specifically disclosed in Figs 2 and 3 and especially in Fig. 4.

ed in the enlargement 29 through which extends the driving axle 3|, inturn driven throughthe difl'erential mechanism housed as at 32 and the drive shaft within the tube 33. A transverse spring 28 is suitably secured at its midportion as 30 at 34 to the frame. The end 2 of the arm 2| is connected to the adjacent end of the spring 28 vby interconnected links 25 and 35,. the axis 26 beingtransverseto the axis 21, the two links i being connected together as at 35. The frame is 35 shown slotted as at 31 and for convenience is u shownelongated and more or less arcuate. This is to permit the arm 22 to oscillate with the shaft relative to the frame l0 and without interference therefrom. 40

,The suppo'rtedportions l3 and 23 of the levers. which extend rearwardly andoutwardly from said supported portions for independent wheel suspension, include a substantially cylindrical housing 40. Mounted within the same is a friction brake shoe construction ll having friction lining 42 thereon. The housing has a plate portion 23 and a central support 43 is apertured as at 44 to receive a pivot member in the form of a bolt 45 capped by an ornamental nut 46.

The belt 45 is carried by a plate 41 which has formed integral therewith an elongated portion that terminates in two aligned trunnions 49 which are oppositely directed. These trunnions are each-supported by a bearing block 50 havin The rearward wheels 2| are rotatably 'support- 25 conventional manner and herein two bolts 82 are illustrated. With the aforesaid construction,

plate 41 is pivoted upon an axis coaxial with the tirunnions 48 and which is transverse to the axis of the lever pivot and the two intersect.

Herein the reenforcement ll of the frame includes a pair of substantially vertically aligned openings ll which are'threaded and each receives an externally threaded adjusting sleeve 2 that terminates in a tool engaseable and bearing head 63. This sleeve is hollow and the plate 41 is socketed or recessed as at 64. A bolt 65 having the head portion "is seated in the socket portion 4 and extends through the plate 41 as at 61.;

The threaded end 68 of said bolt 85 mounts a nut 69 that bears on the-end III of the threaded sleeve. The camber of the wheel is adjusted by loosening or removing nut 69 and moving one of thethreaded sleevesinwardly relative to the frame and the other outwardly until the plane of the plate 41 is at an angle to the vertical corresponding to the camber desired. Thereupon the nuts are replaced or threaded home which draws the plate 41 tightly against the bearing heads 63 of the threaded sleeves, the plate in the initial adjustment tilting upon the axis of the trunnions. This provides for adjustable camber for each wheel and the lever mounting provides for independent wheel suspension.

The independent wheel suspension is that each wheel is supported at or near one end of a lever arm,'the axis of the. supported end'of the lever arm being substantially transverse to the longi- .tudinal axis of the frame and associated with the lever arm, at or near the endopposite the sup-- ported end, is a spring construction, herein shown in all instances with respect to the modification of the invention shown in Figs. 1 to 4, inclusive, as being of the transverse type sincelthis form of the invention is more adaptable to transverse spring association, although it may well be associated with longitudinal springs, reference be-.

ing had to the longitudinal axis of the frame or vehicle. As previously set forth, included within the cylindrical chamber formed by the supported end 23, the cylindrical portionwintegral therewith and the plate 41, is the shoe construction ,4l having the lining 42 associated therewith.

It will be apparent that with reference to the form of the invention shown in Figs. 1 to 4, in-

elusive. that each wheel is independently mounted relative tothe frame so that it is capable of up and down movement with reference to the opposite axially aligned wheel and the wheel support is adiustably mounted to provide for the desired camber.

While the invention has been set forth in con-- siderable detail in the foregoing descriptionand illustrated in considerable detail in the drawings, the aforesaid is to be considered as illustrative and not restrictive in character. The m0difica-- tion illustrated herein, and many" others, which willreadily suggest themselves to persons skilled in this art, all are considered to be within the broad scope of this invention, reference being had to the appended claims.
