Abstract
Abstract The invention relates to the alignment of motor vehicle wheels and axles. A first embodiment is disclosed for an apparatus comprising a means to hook over an adjustable mounting shaft on a steer wheel providing at least partial rotation thereof, a transverse suspension member attached to the hanger with a light source retained in a bracket and rotatably mounted on a non adjustable mounting shaft at one end thereof and a counterweight at the other. The connections of the hook means and the light source bracket to their respective mounting shafts are such that the mounting shaft is held between a clamping means and two points on each side of the hook means and light source bracket respectively. The clamping means disclosed is a threaded member with a spring loaded ball in one end which engages a circumferential groove on the respective mounting shaft. The second embodiment substantially comprises the light source bracket of the first embodiment adapted for mounting directly onto a directionally adjustable mounting shaft attached to a non-steering wheel of a motor vehicle. Preferred embodiments use laser light sources and include a calibration means to vary the orientation of said light source.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
325 words
A wheel or axle alignment apparatus comprising: a directionally adjustable mounting shaft adapted to be mounted parallel to the axis of rotation of a wheel of a vehicle; hanger means adapted to hook over said directionally adjustable mounting shaft comprising a bottom, two spaced parallel side plates, at least one transverse separating member between said side plates for separating said side plates, identical recesses in each of said side plates adapted for receiving said directionally adjustable mounting shaft therein, a pair of contact points on each of said side plates within each recess thereof engageable with said directionally adjustable mounting shaft, and clamping means adapted to contact said directionally adjustable mounting shaft at right angles and to clamp said directionally adjustable mounting shaft in a triangulated manner between said clamping means and said pairs of contact points; a transverse suspension member rigidly connected to said bottom of said hanger means and having ends thereon; a non-adjustable mounting shaft at one end of said transverse suspension member; and a light source retaining bracket comprising two spaced parallel side plates, at least one transverse separating member between said bracket side plates for separating said bracket side plates, identical recesses in each of said bracket side plates adapted for receiving said non-adjustable mounting shaft therein, a pair of contact points on each of said bracket side plates within each recess thereof engageable with said non-adjustable mounting shaft, and bracket clamping means adapted to contact said non-adjustable mounting shaft at right angles to clamp said non-adjustable mounting shaft in a triangulated manner between said clamping means on said bracket and said pairs of contact points on said bracket so that said bracket is at least partially rotatable on said non-adjustable mounting shaft, and a light source retaining means on said bracket so that a beam of light from a light source retained by said retaining means is projectable at approximately right angles with respect to said transverse suspension member.
Claim 2
Dependent Claim
325 words
A wheel or axle alignment apparatus comprising: a directionally adjustable mounting shaft adapted to be mounted parallel to the axis of rotation of a wheel of a vehicle; hanger means adapted to hook over said directionally adjustable mounting shaft comprising a bottom, two spaced parallel side plates, at least one transverse separating member between said side plates for separating said side plates, identical recesses in each of said side plates adapted for receiving said directionally adjustable mounting shaft therein, a pair of contact points on each of said side plates within each recess thereof engageable with said directionally adjustable mounting shaft, and clamping means adapted to contact said directionally adjustable mounting shaft at right angles and to clamp said directionally adjustable mounting shaft in a triangulated manner between said clamping means and said pairs of contact points; a transverse suspension member rigidly connected to said bottom of said hanger means and having ends thereon; a non-adjustable mounting shaft at one end of said transverse suspension member; and a light source retaining bracket comprising two spaced parallel side plates, at least one transverse separating member between said bracket side plates for separating said bracket side plates, identical recesses in each of said bracket side plates adapted for receiving said non-adjustable mounting shaft therein, a pair of contact points on each of said bracket side plates within each recess thereof engageable with said non-adjustable mounting shaft, and bracket clamping means adapted to contact said non-adjustable mounting shaft at right angles to clamp said non-adjustable mounting shaft in a triangulated manner between said clamping means on said bracket and said pairs of contact points on said bracket so that said bracket is at least partially rotatable on said non-adjustable mounting shaft, and a light source retaining means on said bracket so that a beam of light from a light source retained by said retaining means is projectable at approximately right angles with respect to said transverse suspension member.
Claim 3
Dependent Claim
