     BACKGROUND OF THE INVENTION 
     In the repair of automobile bodies the work can be performed in a welding shop which often involves the use of welding equipment as well as cutting torch equipment, and such use of equipment requires water sprinkler apparatus applied to areas under repair to prevent heat and fire damage. 
     BRIEF SUMMARY OF THE INVENTION 
     The object of the invention is to provide a water sprinkler apparatus that is capable of applying water as a cooling medium and fire control to areas in and on an auto body requiring repair when using heat generating methods of carrying out a repair operation. 
     A further object is to provide a water sprinkler apparatus capable of being inserted into an auto body cavity to apply cooling fluid to the area undergoing exterior repair. 
     Other objects and advantages associated with water sprinkler apparatus will be set forth in the following details.

     DETAILED DESCRIPTION OF THE INVENTION 
     The following detailed description illustrates the invention by way of example and not by way of limitation. This description will clearly enable one skilled in the art to make and use the invention, and describes several embodiments, adaptations, variations, alternatives and uses of the invention, including what I presently believe is the best mode of carrying out the invention. 
     The sprinkler apparatus of FIG. 1 is composed of a flexible tube 10, capped at one end 11 and provided with a control valve 12 at the opposite end with an adjustment handle 13 adjacent a supply tube 14 threaded onto the valve 12 so that cooling fluid from a remote supply can be made available to the tube 10. The tube 10 is provided with a series of cooling fluid outlet ports 15 extending along the tube length and opening at opposite sides. A second series of ports 16 are provided that open in four circumferentially spaced ports, and lastley near the capped end 11 a third series of ports are formed at 17 with four outlets. 
     The view of FIG. 2 illustrates the arrangements of the delivery ports for the cooling fluid. By comparing the respective views of FIGS. 6, 7 and 8 with FIG. 2 it is seen that the ports 15 of FIG. 8 deliver the cooling fluid from opposite sides to form delivery sprays 15S. The delivery of cooling fluid at ports 16, as in FIG. 7, is from ports spaced at 90° around the tube so that spray 16S will be directed out of four sides of the tube. Finally, the end ports 17 of FIG. 6 are sized to deliver cooling fluid at spray 17S. 
     The sizing of the cooling fluid outlet ports is best seen the FIGS. 6, 7 and 8. The port 15 are spaced apart at 180°, have a bore size of 0.040&#34;, and are spaced along the tube 10 at intervals of about 3/4 inches. The second series of ports 16 open at 90° and are of the same bore size of ports 15 and are spaced at intervals of 1/2 inch. Finally, the ports 17 open at 90° spacing and have a larger bore of 059&#34;. It is desired to concentrate the flow of cooling fluid adjacent the end of the tube 10 where the greatest heat is applied by the cutting torch or where the welding occurs, while the rest of the cooling flow ports deliver cooling effect surrounding the area under repair either by the heat of a cutting flame or the heat from the addition of welding material. Furthermore the sizing of the ports from the smallest at the inlet end to the largest at the remote end of the tube 10 reflects the distribution of the cooling flow to assure an adequate quantity where the heat from repair work is generally concentrated. 
     FIG. 3 illustrates the use of the cooling fluid sprinkler apparatus in the area under an auto fender 20 where the heat from a cutting torch 21 is concentrated. The cooling fluid tube 10 is positioned where the cooling fluid is concentrated so that heat picked up by the frame of the auto wheel well 22 is rapidly cooled so the distructive heat is dissipated. In the view of FIG. 3, the repair work is being performed on a Corvette which has a FIBERGLAS body that is subject to heat damage from welding or cutting equipment. 
     A further example of the utility of the sprinkler apparatus is seen in FIG. 9 in connection where a weldment 23 is being applied to an auto body 24, to establish a connection between a panel 25 of the body 24 and panel 26 of the top. In this application the trunk cover is removed so that the cooling tube apparatus 10 can be inserted under the interior of the panel 26 to control the heat generated by the exterior deposits of welding material 23 to connect the body panel 24 to the top panel 26. 
     The view of FIG. 2 illustrates the effect of the spray control obtained by adjusting the adjustment handle 13 to select the strength of the spray from the several spray ports 15, 16 and 17. 
     In view of the above, it will be seen that the several objects and advantages of the present invention have been achieved and other advantageous results have been obtained. 
     As various changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
