         [0012]     2. Description of the Prior Art  
         [0013]     Existing repair methodologies lack standardization in both process and apparatus in the correction of damage. The technician is often burdened with customization of the methods and tools used to repair damage on a per job basis increasing the duration of the process and necessitating the use of tools both costly and cumbersome to operate.  
       SUMMARY OF THE INVENTION  
       [0014]     In one of its aspects, the present invention provides a process for the technician to be able to perform collision repair, and offers the technician a standardized process which may be applied to the maximum number of problems with a minimum of effort, to recommend the tools, from a standardized kit, which the technician will require in order to carry out the steps in this process, to thereby reduce the time and/or cost of repair, and/or to minimize secondary damage that may be caused by the implementation of inappropriate methods and/or tools.  
         [0015]     In another of its aspects the present invention provides a universal system and comprehensive mechanism for the repair of automobiles which is free from one or more of the defects of the prior art repair methodologies. In accordance with the present invention, a universal system of repair is provided that will elevate the vehicle from any level surface and allow its transport to any predefined repair zone. In this aspect, the present invention provides the facility to elevate, secure onto apparatus and move any passenger automobile without refitting for width and length variation. Once in the repair zone, the vehicle can be anchored to conventional, repair industry standard, floor mounted anchor points integrating into the base clamp and/or can be independently stabilized by locking the repair apparatus into position. Rotation of the vehicle can be then achieved by unlocking three of the four locking points and then rotating about the axis of the remaining locked point. Further, this aspect provides facility for additional high resolution spot anchoring to the damaged regions of the automobile reducing unnecessary stresses to undamaged regions during the repair process thereby minimizing secondary damage to an unperceivable level.  
         [0016]     In yet another aspect, the present invention is to provide a standardized method and complimentary apparatus for the mounting of a threaded shaft onto a medium such as the metal structure of a vehicle to provide a sturdy attachment means for the purposes of applying force to correct structural damage. Further, this aspect of the invention provides a versatile and adaptive means of attachment in regions otherwise inaccessible or difficult to access thereby limiting the subsequently applied forces to the damaged region. This method provides the mechanic with an economic and/or time saving method in the selection and application of the appropriate apparatus herein.  
         [0017]     In another of its aspects, the present invention is to provide a tool to correct damage or distortion in a medium, such as a vehicle body or frame, where the work is inaccessible or only partly accessible. Further, this aspect of the invention provides the facility within said tool for proper anchoring at the site of the work, to offer the operator at least two axes of rotation about the site of the work in order to efficiently apply forces as required, to provide adaptable means to clear obstructions to the work, and/or to reduce the potential of secondary damage caused by the use of inappropriate tools. Another aspect of the invention is to increase safety in the immediate environment of the apparatus by allowing the operator to rigidly mount said apparatus before the application of force thereby eliminating the possibility of the device being disengaged when unattended. A further aspect of the invention aims to standardize the apparatus required to perform said tasks.  
         [0018]     In another of its aspects, the present invention is to provide a process for the mechanic to create an anchor point on a damaged medium in order to apply corrective forces to said anchor point. A further aspect of this invention is to offer the mechanic a standardized process which may be applied to the maximum number of problems with a minimum of effort, to recommend the tools, from a standardized kit, which the mechanic will require in order to carry out the steps in this process, to thereby reduce the time and/or cost of repair, and/or to minimize secondary damage that may be caused by the implementation of inappropriate methods and/or tools.  
         [0019]     In another of its aspects, the present invention is to provide a tool which is versatile in scope, effective in clearing obstructions to its application, and sufficiently sturdy to withstand forces applied to correct damage a the site of the work. Further, this aspect of the invention is to provide a single platform that may be used to guide a drill or to establish a rivet in a medium without having to resort to the use of several tools exclusive to each task. In another of its aspects, this invention aims to reduce the cost of repair, in both time requirements and/or tool requirements. The aim of the present invention is to reduce the occurrence of secondary damage that may be caused by improperly applied forces by providing the operator the facility to mount the apparatus, and to thereby apply forces, as close to the desired point of application as possible.  
         [0020]     In another of its aspects, the present invention is to provide a method and apparatus for the installation of threaded rivets into a medium which is inexpensive, simple in design, allows the operator versatility in application, allows the operator freedom of one hand, and permits the installation of said rivets from one side of the work.  
         [0021]     In another of its aspects, the present invention is to provide a facility to reinforce an existing, installed rivet. An additional aspect of this invention is to allow the technician to select a level of reinforcement as required by the work thereby increasing the stress bearing facility of the system of the washer and the rivet to levels unattainable by the rivet alone. In the absence of a suitable site for a rivet but where a washer may be installed, the technician is provided the facility to use the washer as a stand alone device to bear the stresses of the work that would otherwise be borne by a rivet. It is the aim of this invention to provide the technician with a tool that is economical and simple to implement in the event that a rivet requires reinforcement or in the absence of a rivet.  
         [0022]     In yet another of its aspects, the present invention is to provide a method and complimentary apparatus for drilling into a medium under conditions unsuitable for existing systems and apparatus, is inexpensive, compact in design, versatile in application, is capable of performing its intended function under tight tolerance and at the site of the work such as that required for the installation of brackets, allows the operator to concentrate applied forces to rotation and not against the face of the work thereby reducing fouling of the drill bit and resulting in a hole perpendicular to the face of the work. Further aspects of this invention are to provide a method and apparatus for the drilling of holes into a medium which may be performed at low rotation speeds reducing the generation of heat at the site of the work without lubrication and/or at high rotation speeds where a localized air cooling facility may be engaged.  
         [0023]     In another of its aspects, this invention is to provide a tool which is effective in clearing obstructions to its application, compact, simply applied, and sufficiently sturdy to withstand forces applied in the drilling of holes at the site of the work and to allow the drilling to be performed at an angle to the plane of the work desirable to the operator. Further to this aspect of the invention, a means to reduce heat resulting from the action of drilling and to safely remove drilling exhaust in the form of fragments which can otherwise obstruct the drilling action or injure the operator is provided. In another aspect, this invention is to reduce the cost of drilling in both setup time and tool requirements. In this aspect, it is the aim of the present invention to provide a means for the operator to accurately define the location of the intended hole(s).

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0115]     In accordance with an embodiment of the present invention, a process is provided for collision repair where the following steps summarize the effort: 
        damage assessment is performed to inform further steps;     the collision repair process is invoked where the technician is to follow the instructions outlined in the proposed process and make decisions based on the requirements of the work as part of the process; and     upon completion of this process, the technician is ready to apply forces at appropriate points as required by the work.        
 
         [0119]     The collision repair process noted in the above steps will be better understood with reference to the drawings as listed in the description of drawings above.  
         [0120]     The description of the collision repair process will be discussed in detail with reference to FIGS.  1  to  9 . A collision repair process is provided as in  FIG. 1  wherein a flowchart format is used to best illustrate the steps involved. The collision repair process flowchart is comprised of several steps which take the form of either an action to be taken or an action preceded by a decision to be made by the technician. Arrows are used to indicate the direction of flow.  
         [0121]     The start terminal  1  is the initialization of the collision repair process. The technician must identify the damage that is to be repaired using the process.  
         [0122]     The decision  2  offers the technician the option of utilizing a mobile, 4 point anchor apparatus whereby the vehicle under repair is raised onto beams and is anchored thereto while said apparatus may be moved on the work floor as required. This determination is dependent on the location of the damage on the vehicle where undercarriage damage would strongly suggest an affirmative response.  
         [0123]     The action  3  is invoked if the technician has determined that the mobile, 4 point anchor apparatus, such as that in  FIG. 8 , is required for the work. The anchor apparatus allows the technician to raise the vehicle to the desired height and to anchor appropriately. After completion of the anchoring, the technician may proceed to implement the hook-up process  4  as described in detail with reference to  FIG. 2  below.  
         [0124]     If the anchor apparatus is determined to be unnecessary in decision  2 , the technician may directly proceed to implement the hook-up process  4  as described in detail with reference to  FIG. 2  below.  
         [0125]     Decision  5  is offered after the successful implementation of the hook-up process  4 . Stress relief is offered where it is not desirable to directly apply forces of great magnitude, where anchoring may not be as sturdy as desired, or where the ability to apply forces of great magnitude is hindered.  
         [0126]     If stress relief is determined to be necessary in decision  5 , the action  6  is to be implemented whereby stress relief is attained by means of vibration of the medium under repair or impact such as that provided by a hammer, during the application of force, or additional anchoring is performed at the site of the work.  
         [0127]     After the completion of action  6  or if stress relief is determined to be unnecessary in decision  5 , the technician is given the option of proceeding with either action  7  or action  8 . Action  7  requires the implementation of the apparatus of  FIG. 9  wherein a device is provided which allows the technician to clear obstacles, such as the bumper of a vehicle, and to accurately set and lock the vector at which force is to be applied. The technician may choose to proceed with action  8  wherein force may be directly applied to the site of the work by means of a chain or other pulling or pushing device.  
         [0128]     After the completion of either of the actions of  7  or  8 , the process may be concluded with the application of force at a magnitude and vector appropriate to the work.  
         [0129]     A hook-up process is provided as in  FIG. 2  wherein a flowchart format is used to best illustrate its intended usage. The hook-up process flowchart is comprised of several steps which take the form of either an action to be taken or an action preceded by a decision to be made by the technician as in  FIG. 1 . Arrows are used to indicate the direction of flow.  
         [0130]     The start terminal  10  is the initialization stage of the process. At this stage, a point on the medium to be repaired must be appropriately chosen to be able to correct damage if force is applied at the correct vector through this location.  
         [0131]     The decision  11  offers the technician the option of proceeding with or without the use of mounting holes. This determination is dependent on the site of the work, the magnitude of the force to be applied in respect of the sustaining ability of the mounting spot, and whether a mounting hole is a practical means of attachment of an anchoring device.  
         [0132]     The action  12  is invoked if the technician has chosen to proceed without a hole or holes and is therefore satisfied that a clamping method is sufficient to sustain the forces to be applied in correcting the damage. In this case, a pinch clamp may be used as that illustrated in  FIG. 3 . Once the clamp is attached, the technician may move to the end terminal  21  where a device to sustain the application of force may be attached, such as a threaded hook-up shaft, secured chain, etc., and thus the process is complete.  
         [0133]     The decision  13  is invoked if the technician has determined that the use of a mounting hole or holes is appropriate to the work. In this decision, the technician must respond to the question as to whether mounting holes are present and if so, whether these mounting holes are appropriately located.  
         [0134]     The action  14  is invoked if the technician determines that a mounting hole or holes must be produced. In order to produce a mounting hole, a bracket, as in  FIG. 4 , must be attached with which a drill cartridge, as in  FIG. 5 , is engaged in order to produce a hole. The mounting of said bracket may be achieved by one of three methods from which the technician is to choose the most practical given the work. The methods of mounting the bracket offered to the technician are the use of locking pliers, as in  FIG. 6 , a threaded stud welded to the medium, or a piercing punch, as in  FIG. 7 , in order to create a small diameter hole where a self-tapping screw is engaged to mount said bracket.  
         [0135]     Upon completion of action  14 , the technician is offered the option of using a bracket in decision  15  with which to engage devices which will sustain the application of force or to directly attach said devices. If the technician chooses to waive the bracket option then the process is again completed at end terminal  21  in the attachment of said device(s).  
         [0136]     If the requirement of the bracket is established in decision  15 , then the technician is instructed to mount said bracket in action  20  by means of a threaded rivet, which is to engage a bolt, or a conventional nut and bolt configuration through the newly produced hole(s) in action  14 . Once the bracket is secured, the process may again be completed at end terminal  21  as before.  
         [0137]     Returning to decision  13 , if the technician is able to utilize any existing holes then decision  16  may be invoked. Here, the technician must decide whether to proceed with the aid of a bracket or to directly mount any devices which will sustain the application of force. If the technician chooses to waive the bracket option then the process is completed at end terminal  21  as before. If the technician does require a bracket for the purposes of mounting any devices which will sustain the application of force, then action  17  is to be invoked where the bracket is secured to the medium by means of either a threaded rivet or a nut and bolt configuration as in action  20  above.  
         [0138]     The technician may proceed to decision  18  where the requirement of any additional hole(s), in order to provide additional mounting strength, is to be determined. If additional holes are not required, the technician may proceed to end terminal  21  to complete the process as before. In the event of additional holes required, the technician may proceed to action  19  in order to engage the drill cartridge to produce said hole(s).  
         [0139]     Once the requisite hole requirement is satisfied in action  19 , the technician need only to secure the bracket, by means of threaded rivet or nut and bolt configuration as before, utilizing new mounting hole. The process is then completed at end terminal  21  once any devices which will sustain the application of force have been attached.  
         [0140]     In an embodiment of the present invention a repair zone will be described with reference to  FIG. 10 . The vehicle under repair  28  is intended to be brought within a perimeter described by floor anchor points  24  which are illustrated in their relative positions in the industry defined configuration and further situated in the perimeter described by additional floor anchor points  26 .  
         [0141]     Precise positioning and elevation of the vehicle is attained with the aid of the apparatus which will be described with reference to  FIG. 11 . The elevation and mobility apparatus  46  is secured to crossbeam  30  and a wheel assembly  48  is attached to said crossbeam  30 . The combined elevation and mobility apparatus  46  and the crossbeam  30  is now moved into position such that the unsecured end of the crossbeam  30  is brought under the vehicle  28 , perpendicular to its length, and allowed to extend on the other side of the vehicle  28 . An additional elevation and mobility apparatus  46  is then secured to the unsecured end of the crossbeam  30  after the removal of the wheel assembly  48  which is adjustable and removable by screw clamps  42 . The elevation of the crossbeam  30  relative to the elevation and mobility apparatuses  46  is then configured by the height adjustment bolt  32  which passes through a threaded hole in the crossbeam  30  and then said crossbeam  30  is locked at desired elevation by lock pins  40  providing perpendicularity once tightly secured relative to the height of the elevation and mobility apparatus. The elevation of the elevation and mobility apparatuses  46  relative to the floor is then adjustable by means of bolt  34  and locked by means of screw lever  36 .  
         [0142]     Final positioning of the vehicle  28  is achieved by maintaining the elevation of the elevation and mobility apparatuses  46  above the floor such that the attached wheels  38  are free to move. Immobility is attained by lowering the elevation and mobility apparatuses  46  to the floor thereby rendering the attached wheels  38  incapable of providing movement. Should partial immobility be desired, for rotation, said elevation and mobility apparatuses  46  can be maintained above the floor and said attached wheels  38  can be locked as desired and thus rotation axis defined.  
         [0143]     A second pair of elevation and mobility apparatuses  46  and a crossbeam  30  can then be put into position at the other end of the vehicle  28  as required by the repair.  
         [0144]     The mechanism by which the elevation and mobility apparatus  46  is attached to the crossbeam  30  will be described in detail with reference to  FIG. 15 . The height adjustment bolt  68  passes through a self aligning nut  70  of cylindrical shape contained within the hollow end region of the crossbeam  72 . The axis of rotation of the self aligning nut  70  is defined by the insertion of the set screw  74  through axis hole  78  in the hollow end region of the crossbeam  72  and into the appropriately threaded end of the self aligning nut  70 . Thus the necessary maneuverability of the assembled system, as indicated by the range of angles through which the height adjustment bolt  80  may pass relative to the crossbeam  72 , is afforded until the requisite height is determined and the height adjustment bolt  68  is tightened such that crossbeam  72  is brought perpendicular to the height of the elevation and mobility apparatus  46  with the aid of lock pins  40 .  
         [0145]     Securing the final position of the elevation and mobility apparatus  46 , before repair, will be described with reference to  FIG. 12 . Base clamps  50  are brought into contact with the elevation and mobility apparatuses  46  at those points on the floor deemed critical under stress and said base clamps are secured to floor anchor points  24  or  26  as convenient. Securing to floor anchor points  24  or  26  is achieved by passing the floor anchor bolt  52  through the saw-toothed washer  54  and then passing said assembly through the base clamp  50 , and potentially through appropriately provided anchoring holes  44  on the elevation and mobility apparatus  46 , into the threaded floor anchor points  24  or  26  such that the teeth of said saw-toothed washer  54  come into contact with the saw-toothed edges of the base clamp  50  thereby eliminating movement under stress.  
         [0146]     Securing of the vehicle  28  to the combined apparatus will be described with reference to  FIG. 13 . Two adjustable clamps  56  are attached to a section of crossbeam  58  between the elevation and mobility apparatuses  46  and are spaced according to the distance between the lower sills on the undercarriage of the vehicle  28  and are locked into position by means of bolts  60 . Said distance varies by brand and model of vehicle  28  however the present invention provides universal accommodation for this distance by means of said adjustability. The adjustable clamps  56  are then tightened to the lower sills on the undercarriage of the vehicle  28  by means of clamp bolts  62  thus completing the preparation process for repair.  
         [0147]     Further, spot anchoring is achieved with higher resolution than conventional systems which are typically floor anchored. Such anchoring means will be described with reference to  FIG. 14 . A chain anchor point  66  is affixed to a section of crossbeam  64  at a point outside the perimeter of the vehicle  28  thereby providing anchoring means. Similarly, chain anchor points  66  may be affixed to the elevation and mobility apparatuses  46  providing additional anchoring points. Such high resolution anchoring in the present invention allows the stress of repair to be localized to the damaged region thereby reducing secondary damage which is prevalent in conventional systems.  
         [0148]     In accordance with an embodiment of the present invention, a method is provided for the attachment of an appropriate threaded shaft in preparation for the further attachment of devices enabling the application of force. The attachment of the threaded shaft is performed according to the following steps:

The chain tightening mechanism  196  has a chain  198  attached similar to the configurations previously described.  
         [0175]     An inverted vector transfer apparatus is provided as in  FIG. 88 . The inverted vector transfer apparatus  724  is provided with facility to engage a mounted shaft  722  which is further mounted to the medium under repair  720 . The vector transfer apparatus  724  is supported against the medium  720  by support  728  of material sufficient to withstand distortion under the stresses applied to the chain attachment  726  and serves to distribute forces applied and prevent rotation about the mounting point of mounted shaft  722  where the desired application of force is along the longitudinal axis of the medium  720 . Any of the vector transfer apparatuses may be used in said inverted fashion as required by the work where the operator may find the non-inverted usage impractical or where the forces needed to be applied are better aligned with the inverted vector apparatus  724 .  
         [0176]     A detailed description of the vector lock mechanism will be discussed with reference to  FIGS. 31 and 32 . A vector lock mechanism is provided as in  FIG. 31  comprising an internally threaded cylinder  202 , upper lock bolt  196 , lower lock bolt  200 , mounting panel  194 , and angle setting holes such as hole  198  bored on said mounting panel  194 . The lower lock bolt  200  may be removed to allow the operator to rotate the internally threaded cylinder  202  about the axis of the installed upper locking bolt  196 . Said internally threaded cylinder  202  may be rotated, relative to mounting panel  194 , to the desired angle and then set at said angle by means of reinserting and securing said lower locking bolt  200  at the appropriate hole passing through mounting plate  194 , locking bolt fixture of the internally threaded cylinder  202 , and the opposing mounting plate. A threaded shaft  192  is shown to be engaged with the vector lock mechanism illustrating the facility of the unit to be rotated about the axis of the threaded shaft  192 , maintaining the engagement, allowing the operator to position the vector lock mechanism according to the requirements of the work in this plane.  
         [0177]     A vector lock mechanism is provided as in  FIG. 32  wherein the locking bolt fixtures are exposed. Similar to  FIG. 31 , this vector lock mechanism comprises an internally threaded cylinder  214 , upper lock bolt  208 , lower lock bolt  212 , mounting panel  206 , and angle setting holes such as hole  210  bored on said mounting panel  206 . Said internally threaded cylinder  214  is shown with locking bolt fixtures configured such that when abutted with mounting panel  206 , the upper locking bolt may pass through upper fixture and lower fixture may be aligned with each of the holes in mounting panel  206  such as hole  210  allowing the engagement of lower locking bolt  212  at the desired angle. Holes in the mounting panel  206  are provided, along the abutment path of said lower fixture, allowing a rotation range about the axis of the installed upper locking bolt  208  of approximately 120 degrees at approximately fifteen degree setting increments. It is understood that holes may be provided in this path for varying rotation ranges at varying setting increments without departing from the spirit of the present invention. A threaded shaft  204  is illustrated to be engaged with the vector lock mechanism as in  FIG. 31  and similarly this configuration allows rotation of the unit about said threaded shaft  204 .  
         [0178]     A vector transfer apparatus is provided as in  FIG. 33  where a pulling hook  218  is used to provide corrective forces. The arm attachment  222  is provided as before to clear obstacles to the work. A high resolution vector lock mechanism comprised of an internally threaded cylinder  224 , a rotation window  226 , and an adjustment bolt  228  provides adjustability of the vector transfer apparatus through the full range of angles defined by the rotation window  226 . The rotation of the adjustment bolt  228  about its axis provides the means to set the angle of the arm attachment  222  relative to the static angle adopted by the internally threaded cylinder  224 . The adjustment bolt  228  is prevented from motion parallel to its axis by means of bushings. The high resolution vector lock mechanism is anchored to the site of the work by means of the internally threaded cylinder  224  engaged with a bracket  220  which is further engaged with the medium  216  on which work is to be performed. Anchoring at the site of the work includes but is not limited to the implementation of the bracket  220 .  
         [0179]     A vector transfer apparatus is provided as in  FIG. 34  where a pulling hook  236  is used to provide corrective forces as before. This vector transfer apparatus comprises the same components as those of  FIG. 33  and is shown engaged with a bracket  234 . The head of the adjustment bolt  230  is shown to be accessible and operable by tools readily available to the technician. Removable locking pin  244  is used to engage the adjustment bolt  230  with the internally threaded cylinder  240  and removable locking pin  232 , which additionally provides an axis of rotation for said vector transfer apparatus, is used to engage arm attachment  242  with said internally threaded cylinder  240 .  
         [0180]     In accordance with an embodiment of the present invention, a process is provided for the establishment of an anchor point, a hook-up spot, on a medium in preparation for the application of corrective forces where the following steps summarize the effort: 
        a point on a damaged or distorted contiguous medium, such as the body or frame of a vehicle having been involved in a collision, is chosen as the best suited for force to be applied to correct said damage;     the hook-up process is invoked where the mechanic is to follow the instructions outlined in the proposed process and make decisions based on the requirements of the work as part of the process; and     upon completion of this process, the mechanic is provided the facility to attach those devices which will sustain the application of force, such as a threaded hook-up shaft, bolted chain, etc., while achieving the desired repair.        
 
         [0184]     The hook-up process noted in the above steps will be better understood with reference to the drawings as listed in the description of drawings above.  
         [0185]     The description of the hook-up process will be discussed in detail with reference to FIGS.  35  to  40 . A hook-up process is provided as in  FIG. 35  wherein a flowchart format is used to best illustrate its intended usage. The hook-up process flowchart is comprised of several steps which take the form of either an action to be taken or an action preceded by a decision to be made by the mechanic. Arrows are used to indicate the direction of flow.  
         [0186]     The start terminal  248  is the initialization stage of the process. At this stage, a point on the medium to be repaired must be chosen appropriate to be able to correct damage if force is applied at the correct vector through this location.  
         [0187]     The decision  250  offers the mechanic the option of proceeding with or without the use of mounting holes. This determination is dependent on the site of the work, the magnitude of the force to be applied in respect of the sustaining ability of the mounting spot, and whether a mounting hole is a practical means of attachment of an anchoring device.  
         [0188]     The action  252  is invoked if the mechanic has chosen to proceed without a hole or holes and is therefore satisfied that a clamping method is sufficient to sustain the forces to be applied in correcting the damage. In this case, a pinch clamp may be used as that illustrated in  FIG. 36 . Once the clamp is attached, the mechanic may move to the end terminal  270  where a device to sustain the application of force may be attached, such as a threaded hook-up shaft, bolted chain, etc., and thus the process is complete.  
         [0189]     The decision  254  is invoked if the mechanic has determined that the use of a mounting hole or holes is appropriate to the work. In this decision, the mechanic must respond to the question as to whether mounting holes are present and if so, whether these mounting holes are appropriately located.  
         [0190]     The action  256  is invoked if the mechanic determines that a mounting hole or holes must be produced. In order to produce a mounting hole, a universal bracket, as in  FIG. 37 , must be attached with which a drill cartridge, as in  FIG. 38 , is engaged in order to produce a hole. The mounting of said bracket may be achieved by one of three methods from which the mechanic is to choose the most practical given the work. The methods of mounting the bracket offered to the mechanic are the use of locking pliers, as in  FIG. 39 , a threaded stud welded to the medium, or a piercing punch, as in  FIG. 40 , in order to create a small diameter hole where a self-tapping screw is engaged to mount said bracket.  
         [0191]     Upon completion of action  256 , the mechanic is offered the option of using a universal bracket in decision  258  with which to engage devices which will sustain the application of force or to directly attach said devices. If the mechanic chooses to waive the bracket option then the process is again completed at end terminal  270  in the attachment of said device(s).  
         [0192]     If the requirement of the universal bracket is established in decision  258 , then the mechanic is instructed to mount said bracket in action  268  by means of a threaded rivet, which is to engage a bolt, or a conventional nut and bolt configuration through the newly produced hole(s) in action  256 . Once the bracket is secured, the process may again be completed at end terminal  270  as before.  
         [0193]     Returning to decision  254 , if the mechanic is able to utilize any existing holes then decision  260  may be invoked. Here, the mechanic must decide whether to proceed with the aid of a bracket or to directly mount any devices which will sustain the application of force. If the mechanic chooses to waive the bracket option then the process is completed at end terminal  270  as before. If the mechanic does require a bracket for the purposes of mounting any devices which will sustain the application of force, then action  262  is to be invoked where the bracket is secured to the medium by means of either a threaded rivet or a nut and bolt configuration as in action  268  above.  
         [0194]     The mechanic may proceed to decision  264  where the requirement of any additional hole(s), in order to provide additional mounting strength, is to be determined. If additional holes are not required, the mechanic may proceed to end terminal  270  to complete the process as before. In the event of additional holes required, the mechanic may proceed to action  266  in order to engage the drill cartridge to produce said hole(s).  
         [0195]     Once the requisite hole requirement is satisfied in action  266 , the mechanic need only to secure the universal bracket, by means of threaded rivet or nut and bolt configuration as before, utilizing new mounting hole. The process is then completed at end terminal  270  once any devices which will sustain the application of force have been attached.  
         [0196]     In another embodiment, a method is provided for the installation of a repair bracket at the site of the work in order to facilitate drilling, rivet installation, anchor establishment on the medium. The installation process is performed according to the following steps: 
        selection of the repair bracket according to the intended action or actions to be performed;     affixation of the repair bracket to the medium by a means in accordance with the accessibility of the work, the requirements of the work, and the characteristics of the medium;     engagement of an attachment such as a drill guide, rivet press, anchor, etc., with the affixed repair bracket;     performance of the action of repair; and removal of the affixed repair bracket after completion of the repair process.        
 
         [0201]     The apparatus required to perform the above steps will be better understood with reference to the drawings below as listed in the description of drawings above.  
         [0202]     The description of the universal repair bracket will be discussed in detail with reference to  FIGS. 41 through 48 . A right angle repair bracket is provided as in  FIG. 41  comprised of platform walls such as wall  274 , attachment receptacles such as receptacle  276  which may or may not be threaded or tapered dependent on the configuration of the intended attachment, exhaust paths such as exhaust path  278  which allow the removal of debris at the surface of the medium at the site of the work, and mounting holes such as mounting hole  280  which allow the bracket to be affixed to the medium by various means. A right angle repair bracket is provided as in  FIG. 42  where the configuration of the platform wall  282 , the attachment receptacle  284 , and the mounting hole  286  are further illustrated from a work side view.  FIG. 43  provides an additional view of the right angle bracket highlighting the relative scaling of the platform wall  290  and the attachment receptacle  292 .  
         [0203]     A flat repair bracket is provided as in  FIG. 44  where a single plane platform wall  298  has attachment receptacles such as attachment receptacle  294  and a centrally located mounting hole  296 . A work side view of the flat repair bracket of  FIG. 44  is provided in  FIG. 45  showing attachment receptacle  304  equipped with exhaust paths as in  FIG. 41 , the centrally located mounting hole  302 , and the platform wall  300 .  
         [0204]     A flat repair bracket is provided as in  FIG. 46  mounted to a medium  308  where the attachment receptacle is shown to be tapered unlike those of  FIGS. 41 through 45  facilitating engagement with like attachments. A washer  310  is shown engaged with the work end of the attachment receptacle where said washer may be mounted to the medium  308  by means of weld and when fitted with the repair bracket, provides additional load bearing capacity for the entire repair bracket system should additional load bearing capacity be required by the work.  
         [0205]     An adjustable mount repair bracket is provided as in  FIG. 47  where said bracket is equipped with an anchor  318  should load be desired to be applied thereto. This repair bracket has movable attachment receptacles such as receptacle  322  tightened into position by bolts such as bolts  314  and  316  and further locked into position by the serrated side  320  of the repair bracket. Said attachment receptacles can additionally be tightened or held in their desired positions by a nut with a handle such as devices  312  and  324 . The movement of said attachment receptacles offers the technician the ability to define the relative distance between mounting points as desired thereby providing greater flexibility in avoiding obstacles, utilizing existing holes, or in drilling new holes.  
         [0206]     An adjustable mount repair bracket is provided as in  FIG. 48  where the work side of the bracket is illustrated with attachment receptacles  326  and  328 . The anchor  330  is drawn with dashed lines to indicate its position to be on the opposing side and the serrated surface  332  is shown to be on the work side in order to engage said attachment receptacles  326  and  328  once tightened into position.  
         [0207]     Implementation of an adjustable mount repair bracket is shown as in  FIG. 49  where the repair bracket is affixed to medium  334  which has damage requiring correction  336 . The medium  334  pictured here is similar to that of a automobile frame where a rectangular hollow pipe is common. The repair bracket may be mounted as shown utilizing existing holes to mount attachment receptacles such as  338  that may be tightened from the interior of the pipelike frame by wrench  346 . Three such attachment receptacles are shown where the rightmost receptacle is used as a guide for drill bit  340  rotated by power tool  342  in order that further holes may be produced in order to secure the repair bracket to said medium as required by the work. The anchor  344  is shown to be free to bear the force required to correct damage  336  at the appropriate vector as chosen by the operator. The number and functionality of attachment receptacles engaged on such a repair bracket are only limited by the length of the body of said repair bracket.  
         [0208]     A variation on the mounting technique used to affix a right angle repair bracket is provided as in  FIG. 50  where locking pliers  354  has adjustability along adjustment shaft  356  with arm  348  forcing right angle bracket  350  against medium  352 . The centrally located hole of the bracket as shown in  FIGS. 41, 42 ,  44 , and  45  may be used as an interface to force the right angle bracket  350  against the medium with said locking pliers.  
         [0209]     The locking pliers method of affixing the right angle bracket to a medium is provided as before in  FIG. 51  where attachments are shown to be engaged with said right angle bracket. A drill guide  358  is engaged with said right angle repair bracket on the plane of the medium facing west whereas an additional attachment  360  is simultaneously engaged with the plane of the medium facing south thereby illustrating the facility of the repair bracket in allowing dual plane simultaneous functionality.  
         [0210]     A repair bracket is provided as in  FIG. 52  in order to illustrate the functionality of the repair bracket in allowing the operator to use said bracket in conjunction with a drill guide  368  in order to produce evenly spaced holes, distance between said holes being defined by the relative distances of the attachment receptacles of the repair bracket  366 , through the wall of a medium  364  having a similar configuration as those of  FIGS. 50 and 51 . A plug attachment  370  is used to affix the repair bracket  366  to the work face of the medium while a drill guide  368  is engaged with the free attachment receptacle of the bracket and drilling action is performed. Once a hole is produced, the plug attachment  370  may be used to affix the repair bracket  366  to the medium at the site of the newly produced hole thereby again freeing the other attachment receptacle to produce an additional hole with the aid of said drill guide. Additional holes may be produced by repeating this method as desired resulting in evenly spaced holes such as holes  362 .  
         [0211]     A description of a chain equipped bracket will be discussed with reference to  FIG. 86  and  FIG. 87 . A chain equipped bracket  702  is provided as in  FIG. 86  having an extended chain  704  facilitating the application of force. Said bracket  702  may be mounted to medium  700  at location  706  by welding or nut-and-bolt configuration as shown.  
         [0212]     Two chain equipped brackets  710  and  716  having extended chains  712  and  714 , respectively, are provided as in  FIG. 87  mounted at locations  708  and  718  on opposing sides of a medium under repair providing the operator additional facility to apply force as may be required by the work and where access to the work area may allow.  
         [0213]     A description of the push jack bracket will be discussed with reference to  FIGS. 89 and 90 . Push jack brackets  734  and  730  of male and female configurations, respectively, are provided as in  FIG. 89 . A push jack  732 , commonly available to the technician, is shown engaged with said brackets  734  and  730  which are further engaged with medium  736  subtending the region of damage  736  to be repaired. Said configuration allows the application of force, provided by said push jack  732 , along the longitudinal axis of the medium  738  as required in order to correct the region of damage  736 . It is understood that either the male push jack bracket  734  or female push jack bracket  730  may be used to engage the push jack  732  without the aid of the other as required by the work.  
         [0214]     A male push jack bracket is provided as in  FIG. 90 . Said push jack bracket is provided with a male element  740  in order to engage the female end of a push jack such as push jack  732  of  FIG. 89 . Engagement of &amp; said push jack may be accomplished at any point between positions  746  and  754  through a range of angles  742  greater than ninety degrees. Said push jack bracket is mounted to medium  752  by means of bolt  750  or is welded at points such as  748  or both means may be used to mount said push jack bracket. Said apparatus is provided with a bolt clearance recess  744  in order to allow the free rotation of the push jack through the range of angles  742  as described above without being obstructed by bolt  750 . The range of angles  742  allows force to be applied at various points as required by the work. It is understood that the female push jack bracket is similarly configured with the exception that it has a female element as opposed to the male element  740  as described above.  
         [0215]     In yet another embodiment, a method is provided for the installation of a threaded blind rivet. The process of installation is performed according to the following steps: 
        measurement of medium wall thickness into which threaded blind rivet is to be installed;     selection of the length of threaded blind rivet to be used according to information provided by wall thickness gauge which may be correspondingly coded by colour or otherwise;     engagement of the threaded blind rivet with the threaded lower portion of a mandrel which is inserted into the bore of an appropriately sized anvil; and     deforming of the shank of the rivet, and thus installation within the medium, with the aid of the composite device consisting of the mandrel, anvil, a custom wrench and rotation force applied thereon.        
 
         [0220]     The apparatus required to perform the above steps will be better understood with reference to the drawings as listed above.  
         [0221]     The measurement of medium wall thickness will be discussed with reference to  FIG. 53 . A wall thickness gauge  374  is provided having a width less than the diameter of the hole intended to house the rivet. Preferably, the length of wall thickness gauge  374  is suitable for fitting into the palm of the hand of the operator and its material is of a minimum thickness and rigidity allowing operation in the intended environment without deformation. Said wall thickness gauge  374  is provided such that is has slots  376  and  380  and the hole  378  provided for attachment to a chain or otherwise for simple portability. Said slots  376  and  380  are of equal dimension perpendicular to the length of wall thickness gauge  374  sufficient to engage the medium wall and provide the operator with a relative reading of thickness and are of differing dimensions parallel to the length of the wall thickness gauge  374  offering depths corresponding to the lower range of medium wall thickness for which the method and apparatus for the installation of threaded blind rivets is to be utilized.  
         [0222]     A wall thickness gauge  382  is provided which is similarly equipped with slots  384  and  388  and the hole  386  through its geometric center as those of wall thickness gauge  374  and is of equal length, width, material and material thickness to said wall thickness gauge  374 . Slots  384  and  388  are provided such that their dimensions perpendicular to the length of wall thickness gauge  382  are equal to those of slots  376  and  380  of wall thickness gauge  374 . Slot  384  is provided such that its dimension parallel to the length of wall thickness gauge  382  is marginally greater than that of slot  376 . Slot  388  is provided such that its dimension parallel to the length of wall thickness gauge  382  represents the upper limit of medium wall thickness for which the method and apparatus for the installation of threaded blind rivets is to be utilized.  
         [0223]     Said wall thickness gauges are employed by insertion of the head into the hole intended for the installation of the rivet into the medium and engaging of the slot with the thickness of said medium. The wall thickness gauge which allows the engagement of the thickness of the medium of one slot and does not allow the engagement of the thickness of the medium with the other slot provides the operator with the range for which a corresponding length of rivet is assigned. The assignment of said rivet lengths is environment dependent and it is understood that any number of gauges with appropriate slot dimensions may be used with assignments to any number of rivet lengths, if resolution of lengths should need to increase, without departing from the scope of the invention.  
         [0224]     The threaded blind rivet and the desired installation outcome of said rivet will be discussed with reference to  FIG. 54 . A rivet  390  is provided such that it is of length previously selected, of diameter appropriate to the hole of intended installation, is internally threaded, and is provided with an annular flange  392 . Said rivet  390  may be provided with a coating of commercially available retaining compound to coat the outer surface of said rivet  390  including the under surface of said flange  392 . Said retaining compound is chosen such that its retaining capability is only activated under application of pressure which the rivet  390  will endure during the installation process and will cure under anaerobic conditions provided by the compressed rivet  394  after installation in the medium  398 . The compressed rivet  394 , if coated, will adhere to any surface of the medium  398  to which it is installed with the aid of said retaining compound at any point of contact with said medium  398  between the under surface of the flange of said compressed rivet  394  and the ring  396  formed during the compression and thus distortion of said rivet. Once cured at the site of installation, said retaining compound further prevents movement of said compressed rivet  394  within the allotted hole thus increasing its ability to function under stress beyond that provided by mechanical coupling.  
         [0225]     Further, an anvil assembly is provided in accordance with the present invention and will be discussed with reference to FIGS.  55  to  61 .  
         [0226]     An hollow anvil body  400  is provided as in the cross-section of said anvil body  400  shown in  FIG. 55  having an hollow bore through its center consisting of an upper chamber  402  and a lower chamber  404 . Said hollow anvil body  400  is equipped with two rounded slots  406  on opposing sides at equal elevation.  
         [0227]     A mandrel  408  is provided as shown in  FIG. 56  such that it has a larger top portion thread  410  suitable to engage a large nut, a smaller lower portion thread  414  suitable to engage a rivet and the hole  412  through its center. Said mandrel  408  is of a length allowing said threads  410  and  414  to be spaced at a distance greater than the length of the lower chamber  404  within the hollow anvil body  400 .  
         [0228]     Assembly of said mandrel and said hollow anvil body is shown in  FIG. 57  where the inserted mandrel  418  passes through the anvil body  416 . Said lower thread  414  of said mandrel  418  will emerge through the bottom portion of said hollow anvil body  416  at a length sufficient to fully engage a threaded rivet. Said upper thread  410  of said mandrel  418  will emerge into upper chamber  402  of said hollow anvil body  416  at a length sufficient to engage a nut.  
         [0229]     A nut  422  is provided as in  FIG. 58  such that it will engage the upper thread  410  of a mandrel  430 . A washer  424  and a thrust bearing  426  are provided within the upper chamber  402  of an hollow anvil body  420  to create a reactionary force when said nut  422  is caused to be threaded upon said mandrel  430  and to maintain applied forces parallel to the axis of rotation thereby reducing the possibility of friction between said mandrel  430  and said hollow anvil body  420 .  
         [0230]     A pin  428  is provided such that it will pass through the hollow anvil body  420 , at the rounded slots  406  provided for this purpose, and through the body of the mandrel  430 , at the hole  412  provided for this purpose, thus restricting the relative rotation of said hollow anvil body  420  and said mandrel  430 . The pin  428  is additionally restricted to movement along the length axis of the anvil assembly by the rounded slots  406  thereby providing a means of limiting the movement of said mandrel  430  along this axis thus limiting deformation of the compressed rivet  394 . For further clarification, the side view of a pin  444  passing through an hollow anvil body  440  and a mandrel  442  is shown in  FIG. 60  and the top view of a pin  448  passing through an anvil and mandrel assembly  446  is shown in  FIG. 61 .  
         [0231]     Upon the application of force to a nut  434 , as shown in  FIG. 59 , against the upper thread  408  of a mandrel  438 , said mandrel  438  will be drawn upward through the hollow anvil body  432  along the length axis of the rounded slots  406  where the rotation of said mandrel  438  is restricted by means of the inserted pin  436 . A rivet engaged with the lower thread  412  of said mandrel  438  will be forced against the hollow anvil body  432  at its lower end thereby generating the force required to compress said rivet thereby fixing it within the medium as indicated in  FIG. 54 .  
         [0232]     An anvil wrench will be discussed with reference to FIGS.  62  to  64 . An anvil wrench  454 , as shown from the top in  FIG. 62 , is provided to engage a pin  476  passing through the assembly of  FIG. 64 . Once engaged, the anvil wrench  454  is used to control the rotation of said assembly. The anvil wrench  454  provided thus is equipped with a ring  450  of diameter sufficient to pass freely over the hollow anvil body  470 . Two slots  456  are positioned on said ring  450  such that a line joining said slots would be perpendicular to the shaft of the anvil wrench  454  in the same plane and such that said slots  456  will freely engage said pin  476 . The anvil wrench  454  is fitted with a first attachment  452  perpendicular to the plane of the shaft of said anvil wrench  454 .  
         [0233]     A first attachment  460 , as shown in the side view of an anvil wrench in  FIG. 63 , is provided such that it can support a second attachment  462  thereto in a plane parallel to that of the anvil wrench  464 . Two slots  468 , positioned on the ring portion  458  of anvil wrench  464 , are shown in the shape desired for engagement with a pin  476  of  FIG. 64  and thus rotational manipulation of said assembly of  FIG. 64  is afforded.  
         [0234]     The ring portion  472  of an anvil wrench  470  is shown in engagement of a pin  476  in  FIG. 64 . The geometry of slots  468  allows rotation along the length axis of said assembly of  FIG. 64  to be restricted to that desired by manipulation of the anvil wrench  474 .  
         [0235]     During the installation of a threaded rivet, the anvil wrench  474  is engaged with the assembly of  FIG. 64  such that when force is applied to a nut  434  against the upper thread  410  of mandrel  438 , only movement along the length axis of the assembly of  FIG. 64  is permitted. One handed operation of the apparatus for the installation of threaded blind rivets is permitted when a powered tool, commonly available to the mechanic, is used to engage the nut  434  such that said powered tool is pressed against said second attachment  462  of anvil wrench  464  and is allowed to rest against said first attachment  460 .  
         [0236]     In another aspect of the present invention, the device provided is to be installed at the site of the work where a rivet has been previously installed in a medium. The implementation of the present invention will be better understood with reference to the drawings as listed in the description of drawings above.  
         [0237]     The description of the rivet reinforcement washer will be discussed with reference to FIGS.  65  to  68 . A rivet reinforcement washer  480  is provided as in  FIG. 65  comprised of an raised annular support channel to abut and distribute the load, weld holes  482 ,  486 , and  490  to facilitate mounting the washer, a central hole  488  to clear the intended rivet path, and a moisture exhaust path  484  should moisture or debris collect under rivet reinforcement washer  480 .  
         [0238]     A rivet reinforcement washer is shown as in  FIG. 66  having a central hole  492  and a raised annular support channel  494  illustrating the geometry of said channel  494 . This geometry is chosen such that the inner ring is to be closely matched as a negative to the attachment providing the greatest surface area of contact and such that the outer ring is wedge shaped to provide the greatest possible support under stress.  
         [0239]     A rivet reinforcement washer is provided as in  FIG. 67  where the washer  496  is mounted to a medium  498  and where said washer  496  is positioned such that there is full access to the internally threaded rivet  500  already installed, thereby not interfering with the utility of the internally threaded rivet.  
         [0240]     A rivet reinforcement washer is provided as in  FIG. 68  mounted on a medium  502 . The washer  504  is mounted to said medium by means of welds  506 ,  508 , and  510  along the outer flange of said washer. Due to the low profile of washer  504 , it may be acceptable to allow it to remain attached after its utility has been exhausted. The washer  504  can be easily removed after use by sanding at said weld points or by various other means familiar to the technician should the washer become an obstruction or present cosmetic incongruity after use.  
         [0241]     Applications of the rivet reinforcement washer will be discussed with reference to  FIGS. 69 and 70 . An installed rivet reinforcement washer is shown in  FIG. 69  providing load support for a bracket attachment  512  and offering access to the rivet  516  installed in medium  518 . The inner ring of the raised channel of washer  514  is shown fully abutting the lower portion of the bracket attachment thereby providing the greatest possible load support. The washer  514  is shown without the extended outer flange of those washers illustrated in FIGS.  65  to  68 . The embodiment relating to the presence of the outer flange is to be selected according to the requirements of the work where increasing the diameter of the outer flange increases the load bearing facility of the system but may need to be restricted in order to avoid obstructions at the site of the work.
