Abstract
Abstract Camber corrective adjustment tool having a rigid bar and opposed arms, one of which is fixed relative to the bar, and the other pivoted thereto in a manner to act as a fulcrum relative to the wheel mounting plate, for cooperation with a power unit to flex a trailing arm or McPherson strut suspension element against the weight of the vehicle to correspondingly vary the camber of the wheel coupled to the plate.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
182 words
Corrective adjustment tool for adjusting camber of a wheel carried on a spindle and mounting plate assembly rigidly connected to a camber controlling member such as a trailing arm or McPherson strut while attached to a vehicle, said tool comprising: a base defining support means supporting the tool in operating position; a rigid bar having in normal operating position, a first terminus remote to the mounting plate, first arm means rigidly connected to said bar first terminus at a fixed angle, and, a second terminus adjacent to the mounting plate, second arm means engageable with said mounting plate and pivotally connected to said bar second terminus to define a fulcrum relative to said mounting plate; and force application means engaged between said first and second arms and constructed and arranged to exert spreading or contracting force in parallel with said bar therebetween freely of pressure on said spindle to angularly vary the relative positions of said arms, whereby said mounting plate is pivoted about said fulcrum in camber controlling member bending relation against the weight of said vehicle, and camber adjusted thereby.
Claim 2
Dependent Claim
182 words
Corrective adjustment tool for adjusting camber of a wheel carried on a spindle and mounting plate assembly rigidly connected to a camber controlling member such as a trailing arm or McPherson strut while attached to a vehicle, said tool comprising: a base defining support means supporting the tool in operating position; a rigid bar having in normal operating position, a first terminus remote to the mounting plate, first arm means rigidly connected to said bar first terminus at a fixed angle, and, a second terminus adjacent to the mounting plate, second arm means engageable with said mounting plate and pivotally connected to said bar second terminus to define a fulcrum relative to said mounting plate; and force application means engaged between said first and second arms and constructed and arranged to exert spreading or contracting force in parallel with said bar therebetween freely of pressure on said spindle to angularly vary the relative positions of said arms, whereby said mounting plate is pivoted about said fulcrum in camber controlling member bending relation against the weight of said vehicle, and camber adjusted thereby.
Claim 3
Dependent Claim
30 words
Tool according to claim 1, in which said base comprises a pedestal having a vertical post, and a bracket carried by the post in tool mounting relation in operating position.
Claim 4
Dependent Claim
20 words
Tool according to claim 1, in which said first arm means is fixed at a right angle to said bar.
Claim 5
Dependent Claim
25 words
Tool according to claim 1, in which said second arm means is pivotable to extend on either side of said bar at a desired angle.
Claim 6
Dependent Claim
28 words
Tool according to claim 1, in which said second arm means includes an adapter encircling the assembly spindle in arm means coupling relation to the assembly mounting plate.
Claim 7
Dependent Claim
33 words
Tool according to claim 1, including also a longitudinally adjustable power device defining said force application means, said arm means defining opposed seats for mounting said device between them parallel to said bar.
Claim 8
Dependent Claim
219 words
Corrective adjustment tool for adjusting camber of a wheel carried on a spindle and mounting plate assembly rigidly connected to a camber controlling member such as a trailing arm or McPherson strut while attached to a vehicle, comprising: a tool base comprising a triangular pedestal, a vertical post, and a bracket adjustably mounted on said post carrying said tool horizontally for application to said assembly; and a tool comprising: a rigid bar having in horizontal operating position, a first terminus remote to the mounting plate, first arm means rigidly connected to said bar first terminus at a fixed right angle, and, a second terminus adjacent to the mounting plate, second arm means engageable with said mounting plate and pivotally connected to said bar second terminus in laterally offset relation to define a fulcrum relative to said mounting plate; and force application means engaged between said first and second arms constructed and arranged to exert spreading or contracting force above or below and in parallel with said bar therebetween freely of pressure on said spindle to angularly vary the relative positions of said arms, whereby said mounting plate is pivoted away or toward said remote bar terminus about said fulcrum in camber controlling member bending relation against the weight of said vehicle, and camber adjusted negatively or positively respectively thereby.
Claim 9
Dependent Claim
219 words
Corrective adjustment tool for adjusting camber of a wheel carried on a spindle and mounting plate assembly rigidly connected to a camber controlling member such as a trailing arm or McPherson strut while attached to a vehicle, comprising: a tool base comprising a triangular pedestal, a vertical post, and a bracket adjustably mounted on said post carrying said tool horizontally for application to said assembly; and a tool comprising: a rigid bar having in horizontal operating position, a first terminus remote to the mounting plate, first arm means rigidly connected to said bar first terminus at a fixed right angle, and, a second terminus adjacent to the mounting plate, second arm means engageable with said mounting plate and pivotally connected to said bar second terminus in laterally offset relation to define a fulcrum relative to said mounting plate; and force application means engaged between said first and second arms constructed and arranged to exert spreading or contracting force above or below and in parallel with said bar therebetween freely of pressure on said spindle to angularly vary the relative positions of said arms, whereby said mounting plate is pivoted away or toward said remote bar terminus about said fulcrum in camber controlling member bending relation against the weight of said vehicle, and camber adjusted negatively or positively respectively thereby.
Claim 10
Dependent Claim
16 words
Tool according to claim 7, in which said first arm means comprises a U-cross section element.
Claim 11
Dependent Claim
68 words
Tool according to claim 7, in which said bar second terminus defines a journal, said second arm means is a U-cross section element sized to overfit said bar second terminus and apertured in registration with said journal, and including also a pin coupling said bar second terminus and said second arm means element in pivoting relation to extend on either side of said bar at a desired angle.
Claim 12
Dependent Claim
46 words
Tool according to claim 9, in which said second arm means includes an adapter removably secured to said second arms means element beyond said pivot a distance defining said lateral offset for encircling the assembly spindle in arm means coupling relation to the assembly mounting plate.
