   SUMMARY OF THE INVENTION 
   1. A Brief Description of the Invention 
   The invention is a multipurpose tool for purposes of assembly or disassembly of 1911 style pistols. It consists of two pliers heads serving to form upon closure of one against the other a bushing wrench and pliers. The pliers can serve to grasp and hold a barrel bushing component of such a pistol, and can also function as a wire or spring cutter. Each pliers head is pivotably affixed to a three-sided handle. Each handle services to control a pliers head. Each pliers head is held to the other by way of a rivet. One handle moreover has pivotably assembled to it and within it a series of accessory screwdriver blade components and a file component. The other handle has pivotably assembled to it and within it a pair of accessory punch components, a hexagonal driver component and a round file component. 
   2. An Object of the Invention 
   The instant invention uniquely provides for a bushing wrench serving to aid in the removal and installation of a 1911 pistol barrel bushing component while likewise providing for pliers heads that can perform the clamping tasks of ordinary pliers or serve to cut springs as well as forming the equivalent of a webhole that allows the barrel portion of such a pistol to pass through it and a bottomside round hole before the topside webhole actually tightly engages the bushing component. This feature of the invention allows for a very secure purchase of the bushing much moreso than as with resort to use of other wrenches currently available for grasping the bushing. Such is the case, since, there is automatic alignment of the webhole aspect of the invention with the pistol. The very great advantage to such automatic and eminently more secure purchase of the bushing is the virtually complete obviation of slippage such as, for example, often mars the finish of the pistol. Finally, the invention is readily foldable into a 1911 magazine pouch or into one&#39;s pocket while likewise featuring a number of attached accessory components for purposes of facilitating servicing of such a style pistol with maximal convenience and efficiency.

First screwdriver blade component  6 , second screwdriver blade component  7 , third screwdriver blade component  8  and first file component  9  with reference again to  FIG. 10  are all pivotably conjoined near a second end of handle  3   a  via first screwdriver headhole  32 , second screwdriver head hole  33 , third screwdriver headhole  34  and first file headhole  35  respectively into all of which there is threadably inserted third pivot screw  16  through second topside first handle hole  21  and second bottomside first handle hole  25  with the whole of all of the same being secured by way of threadable insertion of screw  16  into third pivot screw threaded bushing unit  17 , all of which can be seen likewise with reference to  FIG. 10 . First punch component  10 , second punch component  11 , hexagonal driver component  12  and second file component  13  with reference again to  FIG. 10  are all pivotably conjoined near a second end of handle  3   b  via first punch headhole  38 , second punch headhole  39 , hexagonal driver headhole  40 , and second file headhole  41  respectively into all of which there is threadably inserted fourth pivot screw  18  through second topside second handle hole  23  and second bottomside second handle hole  27  with the whole of all of the same being secured by way of threadable insertion of screw  18  into fourth pivot screw threaded bushing unit  19 , all of which can be seen likewise with reference to  FIG. 10 . First handle topside concavity  30  and first handle bottomside concavity  31  are shown in  FIG. 10  cut into the topside and the bottomside of handle  3   a  respectively. Second handle topside concavity  36  is shown in  FIG. 10  as being cut into the topside of handle  3   b . Second handle bottomside concavity  37  as shown in  FIG. 8  as being cut into the bottomside of handle  3   b . Concavities  30 ,  31 ,  36  and  37  serve to facilitate ready access to components  6 ,  7 ,  8 ,  9  and  10 ,  11 ,  12  and  13  respectively by way of simply grasping them individually in-situ as shown in  FIGS. 2 ,  5 , and  7  with a thumb and index finger to thereby open them out for utilization as shown in  FIG. 9 . The intact invention can be readily and conveniently carried about in the folded state as shown in  FIG. 1 .  FIG. 3  illustrates how hollowed out handles  3   a  and  3   b  serve to cradle pliers heads  1   a  and  1   b  when the invention is in a folded state. Grasping handles  3   a  and  3   b  together and pulling each outwardly as shown in  FIG. 4  enables the invention to be readily unfolded for use in terms of assembling and disassembling 1911 style pistols. When the invention is unfolded as shown in  FIG. 2  or  FIG. 6 , the pliers heads  1   a  and  1   b  in apposition to one another in what would then be a closed pliers complex is slid over the barrel of the pistol so as to be positioned to depress the recoil plug of the pistol via the convex shaped pliers base  1   c  of the complex which base  1   c  is located at the bottom of the webhole  1   d  formed by the closure together of heads  1   a  and  1   b  as the complex firmly engages the bushing of the pistol within webhole  1   d . Base  1   c  and webhole  1   d  are shown in numbered form in  FIGS. 2 and 6 . Webhole  1   d  with a perimeter slightly in excess of that of the barrel bushing unit of a 1911 style pistol is found when a first topside cut  44  in the topside of pliers head  1   a  with depth and contour equal to the contour of one-half of a barrel bushing unit of a 1911 style pistol comes into apposition with a second topside cut  45  in the topside of pliers head  1   b  with depth and contour equal to the contour of the second half of the barrel bushing unit described above as when first pliers head  1   a  is closed as against second pliers head  1   b  when the invention is in a wholly unfolded state. In such a state, the lowermost portion of cut  44  and the lowermost portion of cut  45  form base  1   c  all of which can be seen with resort to  FIGS. 2 ,  4  and  6 . The complex so formed by the pliers heads in apposition to one another serves as a wrench device that can readily be utilized to rotate the barrel bushing component of such a pistol a quarter of a turn clockwise to free the recoil plug and recoil spring assembly of the pistol so as to facilitate disassembly of the pistol or alternatively to thereafter rotate the bushing a quarter of a turn counterclockwise to restabilize in place the recoil plug and recoil spring assembly of the pistol so as to facilitate assembly of the pistol. When hole  1   d  circumscribes the bushing of the pistol as base  1   c  depresses the recoil plug of the pistol located thereon just below the bushing component thereof, round bottomhole  1   e  of the complex shown in  FIG. 8  circumscribes the barrel component of the pistol. Roundhole  1   e  with a diameter slightly in excess of the diameter of the barrel of a 1911 style pistol is formed by way of the coming together in apposition to one another of first semicircular cut  42  in the bottom side of pliers head  1   a  which bottomside is, in turn, in apposition with the topside thereof and second semicircular cut  43  in the bottom side of pliers head  1   b  which bottom side thereof is, in turn, also in apposition with the topside of pliers head  1   b.    
   Screwdriver blade components  6 ,  7  and  8  are of various sizes to facilitate removal or installation of pistol grip screws, grip bushings, magazine catch components or the adjustment of sight components on the pistol. Punch components  10  and  11  of differing sizes are utilized to remove or insert the pistol&#39;s hammer pin, mainspring housing retainer pin, facilitate disassembly or assembly of the pistol&#39;s mainspring housing or align sear and disconnector during disassembly or assembly of the pistol. Hexagonally shaped driver component  12  also serves to facilitate removal or installation of screws, magazine catches and two piece guide rods in respect of disassembly or assembly of a 1911 pistol. It also functions to facilitate adjustment of trigger over-travel. File components  9  and  13  of differing sizes enable one to file down variously sized pistol components as needed. The instant invention is an intact unit consisting of virtually all of the tool pieces needed for ready disassembly or reassembly of 1911 style pistols. All of the accessory tool pieces thereof namely accessory components  6 ,  7 ,  8 ,  9  and then  10 ,  11 ,  12  and  13  as are neatly and uniquely pivotably affixed to handles  3   a  and  3   b  respectively as shown as noted above in  FIGS. 2 ,  5  and  7  thereby serve to ultimately provide an extremely useful device for purposes of assembly and disassembly of such pistols that is not only very conveniently all-purpose but likewise eminently portable as well. All of these tools are always to be found together thereby obviating a need to be required to retrieve and replace each of them from and into different places in one&#39;s shop as is presently the case when one would seek to service such a pistol. Likewise the pliers heads clamped in apposition to one another can, in addition to serving as a bushing wrench via webhole  1   d  can also serve as a form of wire cutter device for cutting pistol spring components. Finally, the feature of the invention whereby round bottom hole  1   e  engages the barrel of a 1911 pistol as webhole  1   d  engages the bushing thereof while pliers base  1   c  compresses the recoil plug thereof makes for very secure purchase of the bushing while concomitantly greatly easing the process of pistol disassembly or reassembly. Such secure purchasing of the pistol&#39;s bushing serves to greatly minimize and indeed virtually obviate slippage during the performance of such operations thereby avoiding any marring of the finish of the pistol. 
   In conclusion, for the reasons cited above, the instant invention is respectfully submitted, indeed a device that is truly new, useful and unique.
