3 Claims. 1
This invention relates to wheel gauges and it is primarily an object of the invention to provide adevice of this kind whereby the camber and vcaster of wheels may be readily gauged as to angle.
It is also an object of the invention -to provide I a` device of this kind which permits accurate testing of the Wheels of a Vehicle as to either camber or caster and wherein the device is of a structure to render the same readily portable,
thereby materially facilitating its convenience in use.
additional object of the invention is to provide a device of this kind including an element mounted for adjustment Within certain limitations and which serves as an index to denote the starting point of a testing operation and ings, wherein:
Figure 1 is a view in side elevation of a gauge 4constructed in accordance with an embodiment of the invention, a second position of the extension rod being indicated by broken lines and an associated wheel being also indicated by broken lines;
Figure 2 is a view in front elevation of the structure as illustrated in Figure 1, with a portion of the base broken away;
. Figure 3 is a sectional view taken substantially on the line 3-3 of Figure 1, looking in the direction of the arrows; and
Figure 4 is a sectional view taken substantially on the line 4--4 of Figure 3, looking in the direction of the arrows.
. In the embodiment of the invention as illustrated in the accompanying drawings, B denotes a base of desired dimensions and conguration but Which has its bottom surface at and of such dimensions to firmly rest upon a supporting surface, such as a concrete or board floor or other surface, each of which should be smooth and on the horizontal.
Rigidly secured, as at l, to the base B and preferably at an extremity thereof and at the transverse center of the base B is the lower end of an upright or standard S. This standard S, as herein disclosed, isv of channel form with its intermediate or base portion 2 forwardly disposed with respect to the base B. While this upright or standard S may be otherwise constructed, the channel formation has been found to best comply with the requirements of practice as it provides for lightness Without sacrificing strength.
The upright or standard S is mounted upon the base B in a manner whereby the intermediate or base portion 2 is at right angles to the base B so as to be substantially vertical when the device is in position for use. The portion 2 of the upright or standard S at substantially the longitudinal center is provided with a long slot 3 which extends from substantially one end of the yportion 2 to the other. The outer face of the portion 2 to one side of the slot 3 has provided thereon the ,graduations 4 in inches and which are consecutively numbered from the bottom upwardly, the lowermost number indicating the distance Ifrom that graduation to the surface upon which the base B is placed.
Positioned forwardly of the upright or standard S is a flat meter plate P of desired dimensions and which has its opposed flat faces disposed in a direction lengthwise of the upright or standard S and the inner marginal portion of this plate P is defined by a laterally disposed flange l5 which has close contact with the outer face of the portion 2 of the upright or standard S and which flange f5 extends across or bridges the slot 3.
The ange 5 is @preferably Vat right angles to the plate P and is disposed in a direction toward the graduations 4 and the outer margin of this flange 5 is provided with an outstanding index 6 for coaction with the graduations 4 so that the position of the plate P, or more particularly the meter rod 'I bodily movable with said plate, can be readily determined with respect to the surface upon which the device is positioned for a working operation.
Freely insertible through the flange `il at aligned points spaced lengthwise thereof are the headed members 8 which are also directed through the slot 3. The members 8 are also disposed through a base flange `9 of a guide bracket G and which flange y9 contacts the rear face of the portion 2 of the upright or standard S.
Outwardly of the flange 9, the members 8 have threadedthereon the enlargements l0, herein disF rclosed as conventional nuts, and interposed between eachof the enlargements I0 .and the .flange 9 of the bracket G is an expansible member Il, herein disclosed as a coil spring of requisite tension encircling the member 8` The members or springs Il operate to maintain the anges 8 and 9 in close frictional contact with the opposed portions 2 of the upright or standard S so that the plate P will be eiiectively held in selected adjustment along the slot 3 yet be free for 'readyfmovement under slightstrain or stress along the slot 3 as may be determined by the requirements of practice.
The meter rod 1, hereinbefore referred to, is freely and slidably disposed through the flanges 5 and 9 and through the slot 3 and the forward or front end portion of this rod 1 isprovided'with an outwardly and laterally disposed pin l2 which is directed through an elongated slot' I4 in the tail portion l5 of a swinging index hand orfpointer It which is herein disclosed as in simulation of an arrow. The lpointer .or hand, I6 is freely mounted for *,-swinging movement upon an outstanding trunmon V1 carried by theplateP and disposed laterallytherebeyond in thesame direction as the flange 5.
".The ,ton-edge lB-.ofthe plate P is curved cna radius concentricwith the trunnionl I1 and said plateP immediately adjacent to saidcurvededge I6 is provided with the graduations 19,-preferablyspaced in sixteenthsofan inch. The pointer onhand- Iltis. preferablyat thesame side of .the plateras theangel .and the trunnion I1 extends 4Abeyondgthe oppositeace of the plate y.P and has. freely mounted thereona rock arm 2B.

When it is desired toAtest--afwheel of'a car for cambenthe deviceis placed'near the-outerside vof the wheel upon a horizontal surface and close- 1yY .adjacent to ,the Wheel. The plate P is then lowered to bring the outer pointed end of the extension arm Ornger 25 into contact with the rim ofthe wheel at its lowermost point. This `The linger 4 contact is made by moving the rod i endwise in a direction toward the wheel being tested which will result in a movement of the index or hand I6 out- Wardly with respect to the graduations I9 and after which the arm 2@ is swung to bring the index or finger to the point or register of the index or hand i6. After this operation, the plate P is then moved upwardly and so adjusted along the slot 3gto ,permit the outer pointed end of the rod extension or finger 25 to have proper contact with the rim of the Wheel at the high point thereof.
4The camber of the wheel will cause this adjustment or movement of the rod l to bring the index vor hand it to a position inwardly of the previously ,set arml and the graduations between said previously set arm 28 and the second reading of the index or hand it will readily show the camber. If .the camber should not be as desired, the mechanic will then readily know what is necessary tobe done.
It is to be noted that the pointer'or'hand I 6 in its movement wil?. at no time be `obstructed by the index or ringer 2i and, therefore, the Kextent of inner or outer camber can be determined'with equal facility.
It is believed to be readily obvious that thejdeviceas herein described will be operated insubstantially the same manner hereinbefore *explained for metering camber, should it be desired to meter the caster.
The rod i is herein disclosed as having associated therewith an extension rod or iinger 25Yso that said extension rod or finger may be'readily moved upwardly under such conditions Where/the hub cap of the Wheel being tested may intersect 'the path of travel of the rod i as it is movedup or down which is the case with some of theolder models of cars.
overlying one of the side flanges 26 of the -'upright or standard S rand extending substantially from one end thereof to the other is a plate 2l. This plate 2Iis held in position by the bolts28 or the like and surrounding said bolts 28 between the flange 26 and vthe plate 2l are the washers ,Y 2S whereby the piate spaced as desiredJ from the'adjacent flange 2.
' The adjacent edge of the plate 2l is straight from end to end and substantially parallel with the front face of the portion 2 of the upright "or standards.
Mounted for free movement along the plate 21 is a slide 39 provided in its forward marginal portion with an index or pointer 3l for ycoaction with the graduations ll on the upright or standard S. This slide 3@ has threaded therethrough a binding screw .32 coacting with the plate 21 in a manner whereby the slide 3D may be held in desired selected position along the `plate 21. This slide Siirprovides means for registering such measurements as may be deemed advisable during the use of the device.
It is to Abe noted that the tail portion ilof the index or pointer i6 is of a length to extend below the meter plate P and said extended part is provided with an outstanding knob 33 or the like. This Varrangement provides for the lready and convenient shifting of the rod'l with'a consequent adjustment, of course,'of the index or pointer i6.
From the foregoing description it is thought to be obvious that a wheel gauge constructed 'in accordance with my invention is particularly well adapted for use by reason of the convenience and facility ,with which ,it may be assembled and operated.
