No. 14,558, now US. Pat. No. 3,673,842, filed Feb. 26, 1970, by Anastacio V. Sanchez for Method Of And Apparatus For Repairing Deformed Yieldable Structures.
BACKGROUND OF THE INVENTIO The present invention relates to the repairing of deformed yieldable structures and more particularly vehicle bodies. With the continuous increase in the number of vehicle accidents, the demands for vehicle body repair continues to increase. Heretofore, a highly skilled repairman has been required to repair a damaged vehicle body. Considerable time and skill is required of the repairman. Many facets of the repair require the use of special tools and expertise of the repairman is realized only after long periods of training and experience. Accordingly, vehicle body repair is very costly and time consuming. In fact, it hasbecome common practice to remove the deformed parts of the vehicle body assembly and replace them with new parts SUMMARY OF THE INVENTION The present invention teaches an improved method and apparatus for repairing deformed yieldable structures, such as vehicle bodies. Application of the present teachings substantially lessens the costs, time and required skill over that of the known prior art. The first step in straightening bodies is to get the-body back as nearly as possible to the original shape or contour. Thus, according to the present invention, a deformed vehicle body is placed within a body repair stall. Attachment tools of contour dependent upon the desired contour of the deformed area are engaged to the body about the deformed area. Tension cables are connected to the tools. The cables are guided along a select path establishing a line of action. The cables are joined to the tension jacks thereby placing the cables under desired tension along the line of action. As the tension jacks are adjusted, forces are applied to the area of the body about the engaged tool and the area tends to assume a contour dependent upon the contour of the tool, line of action and magnitude of the tension.

DESCRIPTION OF PREFERRED EMBODIMENTS Illustrated in FIGS. 1A and 1B are apparatus .of the present invention for repairing vehicle bodies. The apparatus, referred to by the general reference character 1 encompasses a stall area 2 in which an automobile body 4 to be repaired may be positioned. The outer periphery of the stall 2 is defined by rack means of the apparatus 1, which also includes a plurality of guide racks 6 each designed to guide a plurality of cables 8 in various vertical and horizontal planes relative to one another. A forward rack 6 is positioned to establish the forward part of the stall, left and right lateral racks 6 are positioned to form the left and right sides of the stall 2 and an optional rear rack 6 is designed to be positioned to form the rear of the stall 2. Within the stall 2 there are a plurality of anchor rings or pins 10 firmly secured to or imbedded within the floor of the stall and joined to anchor cables 12 also joined to the automobile body 4 to be repaired so as to anchor the body 4 in place within the stall.
Viewing the various guide racks 6, each carries a plura'lity of horizontal guide bars 14 at various vertical heights relative to the base or floor of the stall 2. The horizontal bars 14 of each rack 6 are supported vertically by a plurality of support columns 16 which are supported vertically from the floor. The horizontal bars 14 are interconnected by a plurality of vertical guide members 18 positioned and detach'ably secured substantially normal to the horizontal bars 14 by dowels or rods 14a fixed to the bars 14. Each member 18 carries a plurality of individual slots 20 through which a cable 8 may be established by selection of the guide rack 6,
the horizontal bar 14 of the rack and the slot 20 of the select member 18. v On the outside of the stall area 2 the cables 8 are joined to an adjustable tension means in the form of a tension jack 22. Each of the cables 8 may be joined to I a respective tension jack 22 to control the tension on the associated cable; FIG. 2 illustrates in further detail a tension jack 22. The jack 22 includes an eye 24 mounted at the end of a threaded tension bolt 26. The eye.24 is adapted to engage the end of a cable 8. Disposed about the bolt 26 is a load cone member 28 of which the internal surface is smooth such that the tends beyond one side of the wall of the upright mem ber 18 for engagement with a cable 8. The load cone 28 interlocks with the wall about the aperture 20 and extends about the other side of the wall of the upright member 18. The bearing 34 facilitates turning of the nut 38. Thus, as it is desired to apply tension to the attached cable, the locknut 38 is turned on the bolt 26. The tension may be increased or decreased by the turning of the nut 38.
To restore an automobile body, it is necessary to first take into consideration the original contour to which it is to be restored. Different models of automobiles have different contours and body lines. Doors, hoods, deck lids and the body proper of the same automobile have different contours. The contours include high crowns, low crowns, angles, flanges, U-channels, box sections and various other contours for providing physical strength and aesthetic attributes.
The apparatus 1 includes a plurality of different shaped attachment tools to be engaged with the automobile body. The contour of the attachment tools is de pendent upon the point of engagement of the tool with the automobile and the desired contour of the body about the point of engagement. FIG. 3 illustrates a lamp attachment tool 42 to be engaged to the body about a lamp area. The tool 42 includes a pair of arcuate plates 44 and 46 complementary to one another. The plate 44 carries a female guide 48 permanently welded to the top surface. The plate 46 carries a male guide 50 mounted on a top surface and normal thereto and in alignment with the the guide 48 of the plate 44. The male guide 50 carries an eye 52 and the female guide carries a pair of eyes 54 and 56 which eyes may be joined to cable means. Protruding from the side wall of the female guide. 48 is a lock screw 58 which serves to allow adjustment of the span of the tool 42. Accordingly, the tool 42 may be positioned about a lamp cavity and the guides adjusted depending upon the size and shape of the lamp opening. By transmitting a force through the selected eyes by means of a cable in a direction so that the curved surfaces of the tool 42 selectively engage the housing or body surrounding the lamp cavity, the housing and body of the vehicle is restored to approach its original contour.

A spoon attachment 156 of FIG. 12 includes a short, rectangular flat plate 158 which may be of substantial width relative to its length and carry a cylindrical stud 160 supported thereby at an acute angle d.
FIG. 13 illustrates a bumper clamp 162 comprising a unitary member shaped with an arm segment 164 and turned back over an arm segment .166. The arm 166 carries an oblong opening 168 for engagement with a cable.
FIG. 14 illustrates an embodiment of a front end of an automobile body in which a pair of the cavity attachment tools 180 are positioned laterally within the cavity beneath a hood and against the side walls of the cavity. The tools 80 are each engaged by a pair of hydraulic jacks 90 to apply lateral forces and to urge the cavity walls outward and can be urged to move the forward direction.
In operation, an automobile body to be repaired is placed within the stall 2 and the anchor cables 12 tied to the body to secure it in place. Preferably, anchor cables 12 are secured to the front, rear and sides of the body. Next, depending upon the area of the body to be repaired, the desired attachment tools are secured to the body and to an appropriate cable member 8. The cable member 8 is then guided over the guide rack means in a select guide to provide the desired line of action (LA) of the force exerted by the tool against the body. The magnitude of the force along the line of action (LA) is adjusted by controlling the tension jack 22 associated with the particular cable 8.
Assuming that the body 4 is deformable, the deformation depends uponthe amount of tension applied to the cable, the line of action (LA) of the cable and the contour of the attachment tool. Depending upon the nature of the repair to be completed,a number of attachment tools may be simultaneously engaged to various parts of the body. The deformation then is further dependent upon the lines of action, magnitude oftension and contour of the various attachment tools relative to one another. FIG. 14 further illustrates application of the present system about the front part of the body. The cavity attachment tools, as previously discussed, apply a lateral force against the interior surfaces of the side walls to urge them outwardly. The
magnitude of the lateral forces is dependent upon the adjustments of the jack members. This arrangement can be also used to move the walls outwardly and forwardly.,FIG. 4 further illustrates that to straighten the housing about the headlamps, the lamp attachment member 60 may be secured within the cavity in which the headlamp is to be supported. This arrangement may also be employed for straightening a deformed fender associated with the headlamp. The span between the segments 62 and 64 is adjusted and then the cables 8 are secured to the eyes 72, 74 and 76. The tension on each of the cables 8 may then be controlled along the line of action (LA) according to the tension on the jacks 22 tied to the cable. The molding clamp 94 may be engaged to and secured with a drip molding 172 about an automobile as illustrated in FIG. 1B. The clamp assembly 94 may be joined to a cable 8 to secure it in place or to move it along the molding trough. Likewise, the various other attachment tools may be joined to the body and cable means to exert forces on the body. 1 r
