Description:
RELATED APPLICATIONS 
     The present invention was first described in a notarized Official Record of Invention on Jul. 24, 2008, that is on file at the offices of Montgomery Patent and Design, LLC, the entire disclosures of which are incorporated herein by reference. 
     FIELD OF THE INVENTION 
     The present invention relates generally to a barbeque grill accessory and, more particularly, to said barbeque grill accessory which provides a flame suppression means to a heating element without damaging the foodstuffs. 
     BACKGROUND OF THE INVENTION 
     Spending time in the great outdoors is among the most popular fair weather leisure time activities. Quite often, cooking and eating a meal is made part of the outdoor activity. Whether it is a family gathering, at a picnic or just having a cookout, a great deal of time is spent around a barbeque grill. While no one will deny that barbequing food adds a flavor that cannot be beat, it does have some disadvantages. Probably the most prominent disadvantage of barbequing is that inadvertent flame ups from grease and oil can often burn and destroy the grilled food. Many users resort to an external spray container, flame extinguishers, or even a glass of water to extinguish such flame ups as they occur. However, these attempts often leaves water which commonly ends up upon the food being cooked thus contaminating it and perhaps ruining the taste as well or overly dampens the flame or heating element which can also lead to uneven or improperly cooked foodstuff. 
     Various attempts have been made in the past to overcome these disadvantages and provide a means of suppressing flame ups while barbeque grilling food, although the present invention substantially departs from the conventional solutions and in doing so provides a means by which flames can be suppressed or extinguished without damaging the quality of the foodstuff being grilled without the aforementioned problems. Among the relevant attempts to address these problems are several U.S. patents, including U.S. Pat. Nos. 3,756,140; 3,782,475; 5,351,760; 5,511,535; 6,386,093; and 6,631,712. 
     U.S. Pat. No. 3,362,586, issued in the name of Dedoes, describes a barbeque fan and fire quenching accessory comprising a hand held pressurized container with a nozzle and a battery powered fan which provides a stream of liquid and forced air to quench a flame during grilling. 
     U.S. Pat. No. 5,353,880, issued in the name of Green, describes a flame extinguisher system of a barbeque comprising a fluid discharge conduit having a plurality of apertures which force and delivers streams of water onto the heating element. 
     Additionally, ornamental designs for fire extinguishers for grills exist, particularly, U.S. Pat. No. D 372,560. However, none of these designs are similar to the present invention. 
     While these devices fulfill their respective, particular objectives, each of these references suffers from one (1) or more of the aforementioned disadvantages. Accordingly, there exists a need for a means by which the flame ups resulting from the grilling of foodstuffs can be easily extinguished without the disadvantages as described above. The development of the present invention fulfills this need.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The best mode for carrying out the invention is presented in terms of its preferred embodiment, herein depicted within the  FIGS. 1 through 4 . However, the invention is not limited to the described embodiment and a person skilled in the art will appreciate that many other embodiments of the invention are possible without deviating from the basic concept of the invention, and that any such work around will also fall under scope of this invention. It is envisioned that other styles and configurations of the present invention can be easily incorporated into the teachings of the present invention, and only one particular configuration shall be shown and described for purposes of clarity and disclosure and not by way of limitation of scope. 
     The terms “a” and “an” herein do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced items. 
     Referring now to  FIG. 1 , an isometric view of the flame suppression apparatus for barbeque grills  10 , shown in a utilized state upon a barbeque grill  15 , according to the preferred embodiment of the present invention, is disclosed. The barbeque grill  15  is depicted as a common grill used in residential backyards. It is envisioned that the barbeque grill  15  would be heated by any of the conventional fuel or power sources. Such sources include but are not limited to charcoal, wood, propane, natural gas, and electricity. Additionally, the barbeque grill  15  can be any size or style ranging from small tabletop models used for camping, up to and including large grills used in outdoor restaurants or mobile catering operations. The flame suppression apparatus for barbeque grills  10  consists of a storage tank  20  with a top mounted manual pump  25 . The storage tank  20  and manual pump  25  are similar to what may be utilized in an agricultural style sprayer. The storage tank  20  would be filled with common tap water at the beginning of a grilling process. The quantity of water contained by the storage tank  20  would be approximately two (2) to three (3) gallons for a common backyard barbeque grill  15  although smaller and larger storage tank  20  can be utilized as need for respectively smaller and larger barbeque grill  15 . A section of flexible heat resistant tubing  30  connects the output of the storage tank  20  to a control valve  35 . The control valve  35  would be mounted at the side or front of the barbeque grill  15  near the normal operating position of the barbeque grill  15  such that it is easily reached or accessed by the user at all times without bending, stooping, or exposing themselves to the heat or flames emanating form the barbeque grill  15 . The output of the control valve  35  is connected to a series of spray nozzles  40  (not visible in this figure) on the rear of the barbeque grill  15 . Further disclosure on the location and operation of the spray nozzles  40  (not visible in this figure) will be described in greater detail herein below. 
     Referring next to  FIG. 2 , a rear view of the barbeque grill  15 , depicting various components of the flame suppression apparatus for barbeque grills  10  according to the preferred embodiment of the present invention is disclosed. This figure once again displays the storage tank  20 , the manual pump  25 , the flexible heat resistant tubing  30  and the control valve  35  in its aforementioned described location. The output of the control valve  35  is connected to a first tee fitting  45 . The first tee fitting  45  is located in the lower body base  50  of the barbeque grill  15 , such that one side of the first tee fitting  45  projects into the interior of the barbeque grill  15 . The remaining connection to the first tee fitting  45  continues to a second or following tee fitting  55  where the aforementioned connection repeats itself. The number of tee fittings is dictated by the physical size of the barbeque grill  15  with the most common number utilized envisioned to be two (2). The final output connection from the last tee fitting continues to 90 degree tee fitting  60 . The tee fitting  60  provides one (1) projection into the interior of the barbeque grill  15 . The spacing of the various tee fittings as well as the one (1) tee fitting  60  are such that equal coverage inside of the barbeque grill  15  is provided. It is envisioned that the flame suppression apparatus for barbeque grills  10  would be provided on new grills as standard or optional equipment. However, it is also envisioned that the features of the flame suppression apparatus for barbeque grills  10  could be provided in an add-on kit for aftermarket installation on existing barbeque grill  15 . 
     Referring now to  FIG. 3 , a detailed view of the spray nozzles  40  as used with the flame suppression apparatus for barbeque grills  10 , according to the preferred embodiment of the present invention is shown. This view more clearly shows the incoming and outgoing connection into a first tee fitting  45 , a second or following tee fitting  55 , or other tee fittings based upon the physical size of the barbeque grill  15  (as shown in  FIG. 1 ). The flexible heat resistant tubing  30  is connected to the tee fitting by use of locking nut  65  on the fitting body  70 . Said connection is for illustrative purposes only and is not intended to limit the scope of the present invention. Other methods of connection such as crimp on connections, friction connections, flanged connections and the like can be used with equal effectiveness. The lower body base  50  is seen in a cross-sectional view thus exposing grill interior space  75 . The fitting body  70  is provided with a spray nozzle fitting  80  on the grill interior space  75  side. The spray nozzle fitting  80  not only produces a fine water mist spray, but also serves as the connection fitting securing the fitting body  70  to the lower body base  50 . A similar arrangement with the spray nozzle fitting  80  is used to secure the 90 degree tee fitting  60  (as shown in  FIG. 2 ) as provided as the last segment of flexible heat resistant tubing  30 . 
     Referring finally, to  FIG. 4 , an interior view of the barbeque grill  15  depicting the spray nozzle fitting  80  as used with the flame suppression apparatus for barbeque grills  10 , according to the preferred embodiment of the present invention is depicted. The lower body base  50  is visible along with a grilling surface  85  as would customarily be expected. A heat producing element  90  such as coals, a burner, a heating element or the like is also visible beneath the grilling surface  85 . A series of three (3) spray nozzle fittings  80  are located along the rear wall of the t the rear of the lower body base  50 . They are located below the grilling surface  85 , but above the heat producing element  90 . The spray nozzle pattern  95  generated by the spray nozzle fitting  80  are of a flat or fan-like nature. The spray nozzle pattern  95  thus produces a water spray to eliminate any grease dripping induced flare ups while cooking. Operation of the flame suppression apparatus for barbeque grills  10  will be described in greater detail herein below. 
     An alternate embodiment of the present invention provides for said apparatus  10  to be a built-in feature for a grill  15  as an as-purchased item. 
     It is envisioned that other styles and configurations of the present invention can be easily incorporated into the teachings of the present invention, and only one particular configuration shall be shown and described for purposes of clarity and disclosure and not by way of limitation of scope. 
     The preferred embodiment of the present invention can be utilized by the common user in a simple and effortless manner with little or no training. It is envisioned that the flame suppression apparatus for barbeque grills  10  would be constructed in general accordance with  FIG. 1  through  FIG. 4 . 
     As aforementioned described, the flame suppression apparatus for barbeque grills  10  would be installed on a barbeque grill  15  of almost any size, type or fuel source. The invention would be ready to use in the case of a factory assembled version. In the case of an aftermarket version, the user would simply drill the necessary number of holes in the rear of the lower body base  50  and install the required fitting body  70  and secure with the spray nozzle fitting  80 . Additionally, a hole would be required for the control valve  35  which would be installed on a readily accessible surface area on the front of the barbeque grill  15 . At this point in time, the flame suppression apparatus for barbeque grills  10  equipped barbeque grill  15  is ready for operation. 
     The user would first begin operation of the flame suppression apparatus for barbeque grills  10  by filling up the storage tank  20  with water. Next, the manual pump  25  would be installed and manually operated to build up pressure in the storage tank  20  in a conventional manner. At this point in time, the flame suppression apparatus for barbeque grills  10  is prepared and ready for use. 
     The user would then prepare a fire or activate the barbeque grill  15  in a conventional manner. After an appropriate heating time, the various food stuffs would be cooked in a conventional manner. As the various food is cooked, grease and other ignitable products will drip from the food, especially meats, and fall onto the heat producing element  90  below. Under the proper conditions, a flare-up will result where the flames will reach out of the grill interior space  75  and possibly ignite the food being cooked. At this point in time, the user would simply open the control valve  35  releasing a spray nozzle pattern  95  within the grill interior space  75 , thus extinguishing the flame. The user would then turn the control valve  35  back off and resume grilling. Said process would repeat in a cyclical manner until all food is cooked. This process eliminates the necessity of using a spray bottle, a glass of water, or other methods which may contaminate the food items being cooked since the water is dispensed below the food. 
     At the termination of the grilling process, the user would wait for the barbeque grill  15  to cool, and then remove any remaining pressure in the storage tank  20 . Any remaining water would be emptied, thus preparing the flame suppression apparatus for barbeque grills  10  for future use at a later time. 
     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 and method of use to the precise forms disclosed. Obviously many modifications and variations are possible in light of the above teaching.
