Abstract

A vehicle measuring device used in repairing damaged vehicle bodies includes a cross bar secured to opposing sides of the vehicle, and a tram bar having a first end adapted to be pivotally secured to the center point of the cross bar. The second end of the tram bar includes a probe for contacting various symmetrically-disposed points on either side of the vehicle body. The cross bar is supported by standards bolted to the cowl of the vehicle, the height of each standard being adjustable. The length of the tram bar is also adjustable for reaching different points on the vehicle body. Levels are provided on the cross bar and tram bar to ensure that they are horizontal. Pivot pins are also provided at each standard directly above the cowl bolts for allowing the tram bar to be pivoted therefrom. Misalignment of the vehicle body is detected by swinging the tram bar to probe points on the vehicle body that are normally equidistant from the longitudinal axis of the vehicle.

Claims

1. Apparatus for measuring distances along the body of a vehicle, the vehicle having a longitudinal axis, said apparatus comprising in combination:

a. a cross bar adapted to extend laterally perpendicular to the longitudinal axis of the vehicle, said cross bar having first and second opposing ends and a center point midway between said first and second opposing ends;

b. securing means for releasably securing said first and second opposing ends of said cross bar to opposing sides of the vehicle at first and second attachment points, respectively, of the vehicle body that are equidistant from the longitudinal axis of the vehicle body, the attachment points lying in an axis perpendicular to the longitudinal axis of the vehicle body;

c. at least one tram bar having first and second opposing ends, the first end of said tram bar being pivotally secured to the center point of said cross bar, the second end of said tram bar including probe means for contacting various points along the vehicle body as said tram bar is pivoted about the center point of said cross bar;

d. a first pivot point aligned with the vertical axis of said first attachment point and a second pivot point aligned with the vertical axis of said second attachment point, each of said first and second pivot points being adapted to releasably receive the first end of said tram bar.

2. The apparatus recited by claim 1 wherein said securing means includes first and second support standards each having a base for being bolted to the vehicle body, said first support standard including means for engaging the first end of said cross bar, and said second support standard including means for engaging the second end of said cross bar, and wherein said first and second pivot points extend from said first and second support standards, respectively.

3. The apparatus recited by claim 2 wherein the first end of said tram bar has an aperture formed therein, and wherein said first and second pivot points each include a pivot pin, the apertured first end of said tram bar being adapted to releasably engage one of the pivot pins for pivotally securing the first end of said tram bar to one of said first and second pivot points.
