Abstract
Abstract 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 which are coupled at datum points on the vehicle so that an operator can readily gauge 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.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
197 words
An apparatus for straightening and reforming the body and frame of a vehicle comprising: frame means adapted to be positioned beneath a vehicle; force applying means selectively attachable to said frame means for applying a force to a vehicle through an elongated force transmitting element; meansuring means operatively coupled to said frame means; said measuring means being attached to a vehicle to respond to the application of force to the vehicle for a continuous indication of the magnitude of deformation of the vehicle back to its original configuration; said measuring means includes at least one vertically extending element having an end attachable to a datum point on the vehicle; said A means further includes first support means to support said at least one vertically extending element for movement in a first direction and second support means to support said at least one vertically extending element for movement in a second direction perpendicular to said first direction, and said at least one vertically extending element is mounted for independent movement in said first and second directions laterally and longitudinally of the frame means in a substantially horizontal plane in response to the application of force to the vehicle.
Claim 2
Independent Claim
197 words
