A universal measuring bridge for determining the amount of misalignment of the datum points on a damaged vehicle, the bridge including a main beam formed from two extruded box beams, each box beam including a reference surface and an upper and lower track, the box beams being connected with the reference surfaces in a precise parallel spaced relation and the tracks also in a precise parallel spaced relation to each other and to the corresponding tracks on the other side, a slide arm having an upper and lower track and an upper and lower rail on each side and a fixed guide and a movable guide on the bottom for aligning the slide arm on the main beam and a cross slide mounted on each end of the slide arm, the cross slide including a pair of rollers positioned to ride on the lower track on each side of the slide arm and a compensating roller positioned to ride on the upper track, the rollers on the lower track being adjustable with respect to the lower track and movable into engagement with the inside of the rails. An overhead bridge assembly for measuring upper body datum points can be mounted on each end of the main beam, each assembly includes both adjustable cross bars and longitudinally extending bars for supporting both vertical and horizontal pointers.

Universal measuring system

An apparatus for reforming and straightening damaged bodies and frames of vehicles whereby corrective forces are applied to the vehicle through one or more elongated force transmission elements. A force is imposed on the elongated elements respectively by means of a uniquely mounted hydraulic ram which is freely pivotable sideways and limitedly pivotable in a backward direction. Each of the hydraulic rams are attached to a frame situated beneath the vehicle to be straightened whereby the frame further supports a measuring bridge coupled to the vehicle so that the progress of a straightening operation can be readily determined. The measuring bridge includes vertical indicators or gauges which are coupled at datum points on the vehicle so that an operator can readily determine the deformity of the vehicle longitudinally, laterally and vertically with respect to its center line. An operator can gauge the progress of the straightening operation in conjunction with target elements which indicate the ultimate degree of straightening necessary to reform the vehicle. The system thus permits a force to be applied to the vehicle in any desired direction or magnitude until such time as the measuring bridge indicates that the target dimensions have been reached providing a highly accurate and simplified technique of straightening and reforming vehicle bodies or frames.
