Abstract
Abstract A device for adjusting at least one alignment characteristic in a suspension system of an automotive vehicle that includes a wheel support member and a wheel attached to the wheel support member by at least one removable bolt, whose removal permits the alignment characteristic of the wheel to be adjusted. The device includes an adjusting bolt means having a shaft whose diameter is smaller than the diameter of the removable bolt and a mechanism for engaging the adjusting bolt such that the adjusting bolt is axially offset in the bore from which the removable bolt was removed and a mechanism for acting against the wheel assembly due to the offset axial position of the adjusting bolt for movement of the wheel assembly relative to the wheel support and means for securing the bolt in a non-rotatable position once the adjustment of the alignment characteristic has been completed.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
169 words
A device for adjusting at least one alignment characteristic in a suspension system of an automotive vehicle, the suspension system having a wheel support member and a wheel assembly attached to the wheel support member by at least one movable bolt that extends through a bore having an axis, the device comprising: an adjusting bolt means having a shaft that is movable within the bore; means for engaging the wheel support member including tab means projecting into the wheel support member and for engaging the adjusting bolt to position the adjusting bolt for movement of the adjusting bolt to a position offset from an original position; means for moving the wheel assembly by acting against the wheel assembly in cooperation with the means for engaging the wheel support member and for engaging the adjusting bolt to move the wheel assembly relative to the wheel support; and means for securing the bolt in a non-rotatable position by engaging the bolt once the adjustment of the alignment characteristic has been completed.
Claim 2
Independent Claim
169 words
A device for adjusting at least one alignment characteristic in a suspension system of an automotive vehicle, the suspension system having a wheel support member and a wheel assembly attached to the wheel support member by at least one movable bolt that extends through a bore having an axis, the device comprising: an adjusting bolt means having a shaft that is movable within the bore; means for engaging the wheel support member including tab means projecting into the wheel support member and for engaging the adjusting bolt to position the adjusting bolt for movement of the adjusting bolt to a position offset from an original position; means for moving the wheel assembly by acting against the wheel assembly in cooperation with the means for engaging the wheel support member and for engaging the adjusting bolt to move the wheel assembly relative to the wheel support; and means for securing the bolt in a non-rotatable position by engaging the bolt once the adjustment of the alignment characteristic has been completed.
Claim 3
Independent Claim
70 words
The device of claim wherein the bore includes a first and second aperture in the wheel support member and a third aperture in the wheel assembly and wherein the means for engaging the wheel support member and for engaging the movable bolt includes a washer having means for engaging a surface defining the first aperture and for positioning the movable bolt in an offset axial position within the first aperture.
Claim 4
Dependent Claim
53 words
The device of claim 2 wherein the washer includes a fourth aperture and the means for engaging the first aperture of the wheel support member includes a tab member extending into the fourth aperture and extending outwardly from the washer to engage the surface of the first aperture of the wheel support member.
Claim 5
Dependent Claim
25 words
The device of claim 3 wherein the washer further includes a plurality of prongs extending from one side thereof to engage the wheel support member.
Claim 6
Dependent Claim
34 words
The device of claim 2 wherein the means for engaging the wheel assembly includes an adjusting member extending outwardly from the bolt to engage a surface defining the third aperture in the wheel assembly.
Claim 7
Dependent Claim
19 words
The device of claim 5 wherein the bolt includes indicia for indicating the angular position of the adjusting member.
Claim 8
Dependent Claim
26 words
The device of claim 6 wherein the washer includes means for indicating the angular position of the means for engaging a surface defining the first aperture.
Claim 9
Dependent Claim
21 words
The device of claim 7 wherein the means for indicating the angular position includes a handle portion extending from the washer.
Claim 10
Independent Claim
107 words
The device of claim wherein the bore includes first and second apertures in the wheel support member and a third aperture in the wheel assembly and wherein the movable bolt includes a head portion and wherein the means for engaging the wheel support member and for engaging the adjusting bolt includes a passage extending through the head portion and a pin extending through the passage of the bolt to engage an inner surface of the first aperture of the wheel support member and a key extending outwardly from the shaft of the adjusting bolt to engage a surface of the second aperture of the wheel support member.
Claim 11
Dependent Claim
41 words
The device of claim 9 wherein the means for engaging the wheel assembly includes a shim disposed against the surface of the shaft of the movable bolt and acting against an inner surface of the third aperture of the wheel assembly.
Claim 12
Dependent Claim
72 words
The device of claim 10 and further including first and second washers, the first washer being disposed adjacent the head portion of the bolt and having a slot through which the pin extends and including a first plurality of prongs for engaging the wheel support member and wherein the second washer includes a second slot for engaging the key and including a second plurality of prongs for engaging the wheel support member.
Claim 13
Dependent Claim

The device of claim 1 wherein the means for engaging the wheel support member and for engaging the adjusting bolt includes a plate having a slotted aperture extending therethrough and a tab member extending outwardly from a plane of the plate to engage an inner surface of the bore extending through the wheel support member, and wherein the means for moving the wheel assembly includes a shoulder portion extending from the plate and a washer through which the adjusting bolt extends in an eccentric relationship such that when the bolt is rotated, the washer acts against the shoulder to move the wheel assembly relative to the support member.
Claim 14
Independent Claim
125 words
A method for adjusting at least one alignment characteristic in a suspension system of an automotive vehicle, the suspension system having a support member and a wheel assembly attached to the support member by at least one movable bolt that extends through a bore having an axis, the bolt's movement permitting the alignment characteristic to be adjusted, the method comprising: positioning means for engaging the wheel support member including tab means so that the tab means projects into the wheel support member; and moving the movable bolt through interaction against the means for engaging the support member such that the movable bolt is moved from an original position and acts against the wheel assembly moving the wheel assembly to adjust at least one alignment characteristic.
Claim 15
Independent Claim
125 words
A method for adjusting at least one alignment characteristic in a suspension system of an automotive vehicle, the suspension system having a support member and a wheel assembly attached to the support member by at least one movable bolt that extends through a bore having an axis, the bolt's movement permitting the alignment characteristic to be adjusted, the method comprising: positioning means for engaging the wheel support member including tab means so that the tab means projects into the wheel support member; and moving the movable bolt through interaction against the means for engaging the support member such that the movable bolt is moved from an original position and acts against the wheel assembly moving the wheel assembly to adjust at least one alignment characteristic.
Claim 16
Dependent Claim
38 words
The method of claim 13 and further including: providing an adjusting member that extends from a shaft portion of the movable bolt to act against the wheel assembly to move the wheel assembly relative to the wheel support.
