Abstract
Abstract An elongated wheeled bench is provided for predetermined aligned positioning beneath a stationary jack stand supported vehicle body to be straightened and includes, supported therefrom at one end, a vertically adjustable horizontally elongated mount extending transversely of the bench. The mount has a light beam generating head mounted thereon for adjustable positioning therealong and also for angular displacement relative thereto about a first axis paralleling the mount and a second axis disposed normal to the first axis. The head is operable to generate a narrow light beam disposed normal to the second axis and scales are provided to indicate angular positioning of the head about the first and second axes and also longitudinal positioning of the head along the mount.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
74 words
An elongated bench for centered positioning beneath a stationarily supported vehicle body, an elongated linear scale equipped horizontal mounting bar supported from one end of said bench, a light beam generating head, a follower mounted on said bar for adjustable positioning therealong, means mounting said head from said follower for adjusted and predetermined angular displacement relative thereto about a first axis paralleling said bar and a second axis disposed normal to the first axis.
Claim 2
Dependent Claim
74 words
An elongated bench for centered positioning beneath a stationarily supported vehicle body, an elongated linear scale equipped horizontal mounting bar supported from one end of said bench, a light beam generating head, a follower mounted on said bar for adjustable positioning therealong, means mounting said head from said follower for adjusted and predetermined angular displacement relative thereto about a first axis paralleling said bar and a second axis disposed normal to the first axis.
Claim 3
Dependent Claim
29 words
The bench of claim 1 including means supporting the opposite ends of said bar from said bench for vertical adjustment relative to opposite side portions of said one end.
Claim 4
Dependent Claim
39 words
The bench of claim 2 including ground engaging wheels supported from said bench for ease in positioning said bench between a vehicle body stationarily supported in elevated position from a floor surface with which said bench wheels are engaged.
Claim 5
Dependent Claim
59 words
The bench of claim 3 including screw jacks supported from said bench for upward engagement with under surface portions of said vehicle body to transfer some of the weight of said body to said bench and establish frictional contact between said bench and vehicle body and prevent shifting of said bench on said surface relative to said vehicle body.
Claim 6
Dependent Claim
37 words
The bench of claim 1 including vertically and horizontally adjustable scale equipped pointer means supported from said bench for checking the horizontal and vertical positioning of under side components of said vehicle body relative to said bench.
Claim 7
Dependent Claim
28 words
The bench of claim 5 including means supporting opposite ends of said bar for vertical adjustment relative to opposite side portions of said one end of said bench.
Claim 8
Dependent Claim
39 words
The bench of claim 6 including ground engaging wheels supported from said bench for ease in positioning said bench between a vehicle body stationarily supported in elevated position from a floor surface with which said bench wheels are engaged.
Claim 9
Dependent Claim
96 words
In combination with a horizontal support bar positionable normal to a center vertical longitudinal plane of a stationarily supported vehicle body and wherein said bar includes linear scale means extending in opposite longitudinal directions along said bar from a center point thereon through which said plane passes, a light beam generating head, a follower mounted on said bar for adjustable positioning therealong, means mounting said head from said follower for adjusted and predetermined angular displacement relative to said follower about a first axis paralleling said bar and a second axis disposed normal to the first axis.
Claim 10
Dependent Claim
96 words
In combination with a horizontal support bar positionable normal to a center vertical longitudinal plane of a stationarily supported vehicle body and wherein said bar includes linear scale means extending in opposite longitudinal directions along said bar from a center point thereon through which said plane passes, a light beam generating head, a follower mounted on said bar for adjustable positioning therealong, means mounting said head from said follower for adjusted and predetermined angular displacement relative to said follower about a first axis paralleling said bar and a second axis disposed normal to the first axis.
Claim 11
Independent Claim
195 words
The method of determining existing differences in elevation and lateral displacement of corresponding opposite side portions of a vehicle body from a center longitudinal axis of said vehicle body, said method including establishing a horizontal guide axis disposed normal to a vertical plane containing said center longitudinal axis, supporting a mount for adjustable positioning along said guide axis predetermined distances on opposite sides of said plane and for angular displacement of said mount about said guide axis, providing a narrow light beam generating head supported from said mount for angular positioning about a third axis normal to said guide axis, directing the light beam generated by said head on a selected component portion on one side of said vehicle for which there is a corresponding component portion on the other side of said vehicle, noting the linear positioning of said mount along said guide axis relative to said plane and the angular positioning of said head about said third axis, and thereafter reverse positioning said head along said guide axis and relative to said third axis and noting whether or not the light beam generated by the head is incident upon said corresponding component portion.
