Abstract
Abstract The present invention relates to an improved push-pull tool having particular, although not exclusive, application in connection with the setting of camber and caster parameters of an automotive suspension system. The type of suspension system to which the present invention is especially well suited is that exemplified by Ford and Mercury automobile suspensions. Such a system is equipped with an upper control arm which is secured to a frame side rail by means of an inner shaft, about which the upper arm is able to experience limited rotation about a horizontal axis, the inner shaft being mounted to a mounting plate secured to the side frame rail. The mounting plate is slotted to permit limited adjustment of the inner shaft transverse to the axis of the vehicle itself. Typically, the inner shaft is secured to the mounting plate by a pair of bolts disposed immediately inwardly of the bushing assembly disposed at either end of the inner shaft about which the upper control arm is swingably mounted. Access to the inner shaft and the bolts securing it to the mounting plate is through an opening in the upper control arm.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
106 words
An improved push-pull tool comprising an elongated shaft, means at one end of said shaft for applying rotational force thereto, anchor means at the opposite end thereof for securing said end against transverse movement at a point offset from the axis of rotation of the shaft, means defining a claw extending outwardly from said shaft, and means interconnecting said claw means to said shaft such that rotational movement applied to said shaft in a first direction is translated into movement of said claw means away from said point and rotational movement in a second direction is translated into movement of the claw means toward said point.
Claim 2
Dependent Claim
106 words
An improved push-pull tool comprising an elongated shaft, means at one end of said shaft for applying rotational force thereto, anchor means at the opposite end thereof for securing said end against transverse movement at a point offset from the axis of rotation of the shaft, means defining a claw extending outwardly from said shaft, and means interconnecting said claw means to said shaft such that rotational movement applied to said shaft in a first direction is translated into movement of said claw means away from said point and rotational movement in a second direction is translated into movement of the claw means toward said point.
Claim 3
Dependent Claim
66 words
The tool as set forth in claim 1 wherein said anchor means is radially offset from the axis of said shaft such that rotational forces applied to said shaft will cause said shaft to revolve about the axis of said anchor means, thereby causing reciprocation of said claw means commencing in a selected direction with respect to the shaft dependent on the direction of rotation thereof.
Claim 4
Dependent Claim
38 words
The tool as set forth in claim 1 wherein said claw means comprises a plate portion having essentially parallel depending fingers disposed in a preset spaced relation for engagement of a member to be moved by said tool.
Claim 5
Dependent Claim
115 words
An improved push-pull tool comprising an elongated shaft, means at one end of said shaft for applying rotational force thereto, anchor means at the opposite end thereof for securing said end against transverse movement, means defining a claw extending outwardly from said shaft, and means interconnecting said claw means to said shaft such that rotational movement applied to said shaft is translated into reciprocation of said claw means, an eccentric is disposed at said opposite end of said shaft, said eccentric having a pin depending therefrom at a predetermined spaced relation with respect to the axis of said shaft, said pin adapted to permit anchoring of said opposite end of said shaft against lateral movement.
Claim 6
Dependent Claim
115 words
An improved push-pull tool comprising an elongated shaft, means at one end of said shaft for applying rotational force thereto, anchor means at the opposite end thereof for securing said end against transverse movement, means defining a claw extending outwardly from said shaft, and means interconnecting said claw means to said shaft such that rotational movement applied to said shaft is translated into reciprocation of said claw means, an eccentric is disposed at said opposite end of said shaft, said eccentric having a pin depending therefrom at a predetermined spaced relation with respect to the axis of said shaft, said pin adapted to permit anchoring of said opposite end of said shaft against lateral movement.
Claim 7
Dependent Claim
19 words
The tool as set forth in claim 4 wherein said eccentric is fixed to said shaft and rotatable therewith.
Claim 8
Dependent Claim
54 words
The tool as set forth in claim 4 wherein said opposite end of said shaft comprises a reduced portion, said claw means being received on said reduced portion and rotatable therein, and said eccentric being mounted on said reduced end portion so as to secure said claw means against axial movement along said shaft.
