Abstract
Abstract A compensator device for wheel aligning apparatus which allows adjustment of relationship between a wheel and an indicator device in two planes mutually at right angles to each other, as for example, for adjusting the camber and caster of the wheel. The mechanism is constructed so as to substantially remove all backlash and has a pair of thumb screws which allow easy adjustment of the compensator in two planes.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
161 words
A compensator device for adjusting the angular relationship between a pair of members in two planes mutually perpendicular to each other comprising a first plate attachable to one of said members and having an extension on one side which extends outwardly from said one of said members, a second plate pivotally attached on a first axis to said extension of said first plate along one edge thereof, a first thumbwheel with oppositely threaded shafts extending from opposite sides thereof threadedily received through first and second plates adjacent second edges thereof, a third plate formed with an extension which is pivotally attached on a second axis to said second plate along a third edge with said second axis being perpendicular to said first axis, a second thumbwheel with oppositely threaded shafts extending from opposite sides thereof threadedily received through said second and third plates adjacent fourth edges thereof, and said third plate attachable to the other one of said pair of members.
Claim 2
Dependent Claim
161 words
A compensator device for adjusting the angular relationship between a pair of members in two planes mutually perpendicular to each other comprising a first plate attachable to one of said members and having an extension on one side which extends outwardly from said one of said members, a second plate pivotally attached on a first axis to said extension of said first plate along one edge thereof, a first thumbwheel with oppositely threaded shafts extending from opposite sides thereof threadedily received through first and second plates adjacent second edges thereof, a third plate formed with an extension which is pivotally attached on a second axis to said second plate along a third edge with said second axis being perpendicular to said first axis, a second thumbwheel with oppositely threaded shafts extending from opposite sides thereof threadedily received through said second and third plates adjacent fourth edges thereof, and said third plate attachable to the other one of said pair of members.
Claim 3
Dependent Claim
53 words
A compensator device according to claim 1 including a first cylindrical member rotatably supported by said second plate on a third axis parallel to said first axis and formed with a threaded opening transverse to said first and third axes through which one of said threaded shafts of said first thumbwheel is received.
Claim 4
Dependent Claim
53 words
A compensator device according to claim 2 including a second cylindrical member rotatably supported by said second plate on a fourth axis at right angles to said first axis and formed with a threaded opening transverse to said fourth axis through which one of said threaded shafts of said second thumbwheel is received.
Claim 5
Dependent Claim
42 words
A compensator device according to claim 3 including a threaded opening formed in said first cylindrical member parallel to said third axis, and a friction member mounted in said threaded opening and biased against said one threaded shaft of said first thumbwheel.
Claim 6
Dependent Claim
38 words
A compensator device according to claim 4 wherein said friction member is a plastic ball and a threaded set screw receivable in said threaded opening to bias said ball against said one threaded shaft of said first thumbwheel.
Claim 7
Dependent Claim
26 words
A compensator device according to claim 3 wherien said first and second cylindrical members are formed with annular grooves, and flexible O-rings mounted in said grooves.
Claim 8
Dependent Claim
29 words
A compensator device according to claim 1 wherein a slot is cut in said third plate and said threaded shaft of said second thumbwheel extending transversely through said slot.
Claim 9
Dependent Claim
31 words
A compensator device according to claim 7 wherein a locking screw is mounted in said third plate transversely of said slot to tighten said third plate relative to said threaded shaft.
