BACKGROUND 
     1. Field of Invention 
     This invention relates to fire protection, specifically, portable roof top sprinklers. 
     BACKGROUND 
     2. Description of Prior Art 
     Current methods used to prevent houses from burning during a fire is to place a standard lawn sprinkler and hope it doesn&#39;t turn over. The current roof top sprinklers as seen in U.S. Pat. No. 8,24,020 issued to Randall Harward on Apr. 25, 1989, cannot be adjusted to the angle of different roof structures, causing the system to tip over and become useless in its purpose. Installing a sprinkler system within the construction of the roof top as seen in U.S. Pat. No. 5,263,543 issued to Ralph Nigro on Nov. 23, 1993, could interfere with the integrity of the house if a leak should occur, causing costly damage to the structure before it would be detected. 
     OBJECTS AND ADVANTAGES 
     Accordingly, several objects and advantages of this invention are: 
     a. To provide a portable fire protection system. 
     b. To provide a portable fire protection system that is inexpensive. 
     c. To provide a portable fire protection system that can be mounted on different types of surfaces. 
     d. To provide a portable fire protection system that can be mounted on different shapes of surfaces. 
     e. To provide a portable fire protection system that can be manufactured from readily available materials. 
     f. To provide a portable fire protection system that can be mass produced using current manufacturing procedures. 
     SUMMARY OF INVENTION
