Abstract: A laser telemeter is driven on two mutually orthogonal axes by stepper motor assemblies to acquire targets mounted at predetermined points on a vehicle. The distances to the targets and the angular orientations are obtained. A computer equipped with a microprocessor controls the movement of the stepper motors by storing in memory the number of steps made during rotation about each axis, and calculates, from the distance between the telemeter and each point, and from the angles of rotation of the beam between the various points measured, the distance between at least two points. These are automatically compared with known standard distances to obtain discrepancies which indicate the deformation of the vehicle. The targets can be disks with back-reflective material thereon as a peripheral ring and a central dot.

Abstract: Device in which each clamp is mounted at the top end of a support consisting of a vertical screw which, mounted in a horizontal slideway projecting outwards from the repair stand at right angles to the latter, is adjustable vertically and transversely relative to the repair stand by means of nuts engaged on the screw and bearing respectively against the top and bottom faces of the slideway.According to the invention the slideway consists of two parallel bars fixed on a plate at their end situated on the repair stand and associated at their other end with removable connection means.

Abstract: This device employs a telemeter (2) which serves to measure its distance from each point to be measured, pivoting mount (9,10) for orientation of the telemeter about two perpendicular axes of rotation, two stepping and reducing motor assemblies assuring the two movements of rotation, and a computer equipped with a microprocessor intended to acquire each distance measurement measured by the telemeter, to control the movement of the stepping motors by storing in memory the number of steps made during the rotation, around each axis, and to calculate, from the distance between the telemeter and each point, and from the angles of rotation of the beam between the various points measured, the distance between at least two points.

Abstract: A terminal alignment angle set part or end piece for use in a multi-Z-receptor or tower of an alignment bench comprising a frame constructed of sectional pieces on which are disposed one or more towers carrying a head piece thereon, the terminal alignment angle set part, or head pieces, being constructed such that at least two of the head pieces may be operatively connected for sliding and rotationable positioning and be fixed relative to one another and the tower to provide for the simultaneous locating or verification of two points on a motor vehicle body through a single tower or multi-Z-receptor.

Abstract: The installation includes a straightening device whose front end is mounted on feet and whose back end is associated with a lift. The back end of the straightening device is equipped with detachable ramps, as well as detachable platforms extending the ramps. On the upper face of the straightening device is mounted longitudinally movable between platforms and the front end, a carriage intended to receive the front axle assembly of the vehicle. The installation is applicable to loading and unloading of the vehicle on a straightening device.

Abstract: An installation for the repair and the checking of vehicle bodies includes a bench having a rectangular frame made of tubular elements, and a pulling tower the forward end of which is equipped with a coupling device for detachably securing the pulling tower to the bench, the rectangular frame having a flange extending inwardly of the frame along the inner bottom edge thereof, the pulling tower having a base portion adapted to be received beneath the frame and having a stirrup constructed and arranged to engage on the flange and a shoe member carried by an axially movable rod for movement into engagement with the external surface of the tubular element and cooperating with the stirrup and flange to lock the pulling tower to the bench.

Abstract: A vehicle repair system for locating and defining predetermined points of vehicle components to ensure compliance with the vehicle specifications. The system utilizes a common base for interchangeably receiving any one of a plurality of control heads in order to enable the base portion of the system to be utilized in checking and verifying the position of vehicle components for any or a large number of vehicles. Each of the interchangeable control heads is specifically configured for use with a particular vehicle and for locating a component of that particular vehicle so that each of the specific control heads can be utilized in a standard system base eliminating the necessity of individual bases being formed as an integral portion of the position locating or verifying apparatus. In addition, the checking and verification system may be utilized to effect localized repairs or reforming of the automotive components to effect their correct positioning.

Abstract: The apparatus for mounting a damaged vehicle body on a checking frame comprises two cross-members carried by vertical end-plates and rigidly fixed to two mounting-plates. The first cross-member is intended to be fixed directly in holes of the longitudinal members of the checking frame. The second cross-member is mounted in an adjustable position on the longitudinal members by means of two sole-plates. Four vehicle body supports are slidably mounted on the cross-members and capable of receiving detachable positioning elements which are specific to each type of vehicle body. The two cross-members are raised to a sufficient height to permit positioning of the horizontal frame of a measuring device beneath the cross-members. The measuring device can thus rest on the longitudinal members of the checking frame so as to permit all the necessary checking operations.

Abstract: The clamping device comprises a vertical screw for supporting a body-clamping jaw unit. The screw extends through a horizontal slide attached to the side of the checking frame or bench jig and is supported on the slide by slidably mounted bearing-blocks and by clamping nuts. Vertical and horizontal millimeter scales are attached respectively to the screw and to the slide and the body-clamping jaw unit is detachable. The position of the clamping unit can thus be adjusted with accuracy. Detachable mounting of the clamping unit permits rapid exchange for adapting the unit to different vehicle body shapes and designs.

Abstract: In a device for straightening vehicle bodies, a long-stroke traction jack is mounted vertically within a vertical column, the jack body being attached to the lower end of the column. The column is carried by a movable base and can be attached to the ground by means of retaining chains. One end of a traction chain passed over a guide pulley and engaged within the interior of the column is attached to the free end of the jack operating rod.

Abstract: The device for checking the positions of shock-absorber heads of a McPherson suspension system comprises a horizontal cross-beam which is placed above the front end of a damaged or undamaged vehicle body to be checked and which is pivotally mounted on two lateral support brackets. Two sliders mounted on the cross-beam each carry a pivoted control arm, the lower end of which is placed opposite to the center of the corresponding shock-absorber head. Graduated scales placed above each slider and on each control arm provide a direct visual indication of forward or backward angular displacement of the cross-beam with respect to the lateral support brackets and of outward or inward inclination of the control arms of the sliders.

Abstract: Apparatus for the positioning of an automobile vehicle bodywork on an inspection and/or repair gauge block of the type comprising two parallel longitudinal members having an I-section. The apparatus comprises two cross members for disposition beneath the longitudinal members the cross members being mounted for movement along the longitudinal members by means of rollers rolling on the lower flanges of the longitudinal members. The extremities of these cross members each carry, outside the gauge block, a lateral bracket containing a sliding vertical arm the upper extremity of which carries an element adapted to support the base of a vehicle body. This element is movably mounted in the transverse direction while mechanical control structure is provided permitting sliding the vertical arm in order to adjust the position of this support element in the vertical direction.
