     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a fire protection system that includes sprinkler heads with a modified sprinkler that emits several streams of water during operation. 
     2. Description of Related Art 
     Fire protection is essential due to the risks and damage associated with fires. Various forms of fire protection include alarms, sprinkler systems, smoke detectors and carbon monoxide detectors. These forms of fire protection and detection are used in various degrees in order to prevent property damage and injury. Many heavily wooded and rural areas are especially at risk when property is located in the close proximity of these areas. Homes and buildings near wooded areas may suffer significant damage if a fire were to start in a wooded area and spread in to a developed area. Although a general or conventional smoke or fire detection and other suppression methods are available it will be advantageous to have the use of improved sprinkler systems for residential and small building protection. These sprinkler systems may reduce the amount of property damage and therefore provide an alternative means for fire protection. 
     SUMMARY OF THE INVENTION 
     In view of the foregoing disadvantages inherent in the prior art, the general purpose of the present invention is to provide a fire protection sprinkler system with modified sprinkler heads, configured to include all of the advantages of the prior art, and to overcome the drawbacks inherent therein. 
     Accordingly, an object of the present invention is to provide a fire protection sprinkler system with sprinkler head that emit water at various angles thereby providing a widespread distribution of water. 
     Another object of the present invention is to provide a fire protection sprinkler system that may pull water from a natural body of water or a manmade water reservoir enabling use in any location with an available water supply. 
     To achieve the above objects, in an aspect of the present invention, a fire protection sprinkler system with sprinkler heads is described compromising a water supply; a network of hosing connected to the water supply; a plurality of sprinkler heads placed along the network hosing, where the each of the plurality of sprinkler heads include a series of water stream emission points; and multiple streams of water emitted from the water stream emission points, where each stream is emitted at a different angle. 
     These together with other aspects of the present invention, along with the various features of novelty that characterize the present invention, are pointed out with particularity in the claims annexed hereto and form a part of this present invention. For a better understanding of the present invention, its operating advantages, and the specific objects attained by its uses, reference should be made to the accompanying drawings and descriptive matter in which there are illustrated exemplary embodiments of the present invention.

     DETAILED DESCRIPTION OF THE DRAWINGS 
     The present invention relates to a fire protection sprinkler system that includes a modified sprinkler head that is installed over a network of hosing. The sprinkler system in accordance with the present invention provides an effective system to prevent fires and to limit property damage based upon use of the sprinkler system. The sprinkler system in accordance with the present invention may be electrically or solar powered and installed in a permanent fixed position through a network of hosing. Unique to this sprinkler system of the present invention is the sprinkler heads that are utilized along the system. The sprinkler heads include multiple streams of water that are emitted at various angles. This configuration allows the sprinkler head a larger circumference of emission and also more effective multiple streams of water over a wider surface area. The system may also be utilized in a portable form so that it may be installed in remote areas where the water supply can vary from a natural body of water such as a local river stream or lake. Further a water tank may be available for the water supply. In a fixed installation the water supply may be supplied through the municipal water lines. 
     Turning now descriptively to the drawing  FIG. 1  shows a sprinkler head  100  in accordance with an exemplary embodiment of the present invention. Sprinkler head  100  includes a head  40  with a spout  41 . The spout  41  includes a series of water stream emission points  42 . From the series of water stream emission points  42  a series of water streams  43  are emitted at various angles.  FIG. 1  illustrates the various angles with the dotted lines coming from the water stream emission points  42 . In this particular embodiment, five water streams  43  are emitted at the water stream emission points  42  at five angles. The angles may be 16.5 degrees, 21.5 degrees, 26.5 degrees, 31.5 degrees, and 36 degrees. The largest degree is placed at the top of the arrangement and the smallest degree is placed at the bottom of the arrangement. A neck  32  is provided that mounts and supports the sprinkler head  100 . The neck  32  enables the sprinkler head  100  to rotate and spray water in a circular manner around the head  40 . A balance  44  is provided on the opposite side of the water stream emission points  42 . The sprinkler head  100  is mounted onto a sprinkler connection  30 . 
     Referring now to  FIG. 2 , an expanded view of an assembly for stabilizing the sprinkler head  100  is shown. The depiction shows the connection of the sprinkler system to a hose  15 . Hose  15  is a portion of a hose network that is used in a sprinkler system according to the present invention. Each sprinkler head  100  is firmly fixed in position with a mounting stake  35 . The mounting stake  35  includes a spike tip  37  which facilitates the stake  35  driving into the ground during use. An arm  20  extends from the stake  35  with an elbow connector  22  attached to the sprinkler connection  30 . Water flows from the hose  15  through the arm  20  into the sprinkler head  100 . This configuration is repeated throughout the entire hose network so that sprinkler heads  100  are placed over a geographical area for widespread fire protection purposes. Fire detection systems may be provided within the system in order to detect smoke, fire or even heat sensors in order to activate the sprinkler system. Once activated water is emitted through the water stream emission points  42  provided on the sprinkler head  40 . 
       FIG. 3(A)  illustrates a first means of water supply for a portable version of the sprinkler system according to the present invention. The first means may be a water tank  120  filled with water. The water tank  120  includes a spout  122  to which the hose  15  is connected. Alternatively  FIG. 3(B)  illustrates an alternative water supply provided by a river  50 . As shown in  FIG. 3(B) , a supply end  17  transfers water from the river  50  through a motor power pump  50  in to the hose system  15 . The pump or motor  50  receives power from a generator  52  in this particular embodiment. This demonstrates a portable embodiment of the present invention that utilizes the sprinkler heads  100  as shown in the previous figures. This particular system directs five streams of water over a geographical area and provides an effective means for fire suppression. 
     The foregoing descriptions of specific embodiments of the present invention have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the invention to the precise forms disclosed, and obviously many modifications and variations are possible in light of the above teaching. The exemplary embodiment was chosen and described in order to best explain the principles of the invention and its practical application, to thereby enable others skilled in the art to best utilize the invention and various embodiments with various modifications as are suited to the particular use contemplated.
