[0021] The innovation is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the innovation can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate a description thereof. Various embodiments are discussed hereinafter. It should be noted that the figures are described only to facilitate the description of the embodiments. They are not intended as an exhaustive description of the invention and do not limit the scope of the invention. Additionally, an illustrated embodiment need not have all the aspects or advantages shown. Thus, in other embodiments, any of the features described herein from different embodiments may be combined.

[0022] As noted above, there is a long-felt need in the art for a fuel oil siphoning prevention system that prevents theft of #2 fuel from a fuel tank. There is also a long-felt need in the art for a #2 fuel siphoning prevention tool that eliminates chances of theft of fuel from the fuel tank and supply line. Additionally, there is a long-felt need in the art for a novel #2 fuel theft prevention tool that eliminates use of expensive alerts and monitors, and/or hiding/covering the fuel tank from trespassers and thieves. Moreover, there is a long-felt need in the art for a fuel oil theft prevention tool that is installed in the supply line for preventing fuel oil from any type of theft. Further, there is a long-felt need in the art for a fuel oil siphoning prevention system that ensures that a siphon cannot be placed into the fuel tank. Finally, there is a long-felt need in the art for an improved #2 fuel oil anti-siphoning screen that maximizes protection against fuel theft and is simple, convenient, and easy to install.

[0023] The present invention, in one exemplary embodiment, is a mechanical tool for preventing siphoning of fuel oil. The device is configured to be positioned with the fuel tank in both commercial and residential premises and comprising a reduced coupling made of malleable iron having a first female end and a second female end, a hex bushing having male threads and female threads, a torsional spring, a FTGCOP fastener, a heavy duty screen having a plurality of holes disposed therein, the screen is positioned inside the reduced coupling, the spring is positioned on the screen and fastened by the FTGCOP, the hex bushing is positioned on the screen, the hex bushing is positioned around the spring to sandwich the spring and screen between a terminal end of the supply pipe and the reduced coupling.

[0024] Referring initially to the drawings, FIG. 1 illustrates an exploded view of one potential embodiment of #2 fuel oil anti-siphoning tool of the present invention in accordance with the disclosed architecture. The #2 fuel oil anti-siphoning tool 100 of the present invention is designed as a theft prevention tool that can be placed between a delivery pipe 302 and a supply pipe 303 on a fuel tank as illustrated in FIG. 3. The tool 100 includes an anti-siphoning screen 102 made of a lightweight metal or an alloy such as stainless steel. The screen 102 has a plurality of holes 104 disposed thereon for allowing the flow of the oil from the narrow end 108 to the broad end 106 thereof.

[0025] The tool 100 uses a malleable iron reducing coupling 110 formed of 22 femalefemale. The coupling 110 is made from lead-free copper or malleable iron. The coupling 110 is ideal for low-pressure plumbing applications including air, water, oil, natural gas, propane, and steam. The fitting side 112 is a female side and has a nominal size pipe fitting diameter of 2 1/2 in. The opposite fitting side 114 is also a female side and has a nominal size pipe fitting diameter of 2 inches. The maximum operating pressure of the reduced coupling 110 is 250 psi @ 120 Degrees F and is compatible for use with any type of oil or fuel.

[0026] The screen 102 is configured to position between the 2 by 2 femalefemale coupling 110 and a 22 malefemale hex bushing 116. The screen 102 is positioned inside the reduced coupling 110 and then the hex bushing 116 is placed on the top of the screen 102 inside the reduced coupling 110. The hex bushing 116 has male National Pipe Taper (NPT) threads on one end 118 and the female NPT threads on the other end 120 for connecting pipes of different sizes. The hex bushing 116 is preferably made from stainless steel and can be used with air, water, oil, propane, natural gas, steam, and more. The head 122 is hexagonal for increased leverage and use with a wrench and the male threads 118 can also be threaded to the female threads 128 of the first fitting side 112 of the reduced coupling 110.

[0027] A support spring 124 is used for holding or biasing the screen 102 inside the reduced coupling 110 (i.e., reducing coupler). The spring 124 is preferably a torsional spring and is fastened using BU FLSH FTGCOP fastener 126 (i.e., flush bushing). The spring 124 does not obstruct the flow of oil through the screen 102 and helps in tight attachment of the tool 100 in a supply line or pipe. It should be appreciated that the #2 fuel oil theft prevention tool is compact in size and can be fixed to any fuel oil supply line for preventing siphoning of the oil. Also, flow is maintained in one direction, thereby eliminating any fuel siphoning. The flush bushing 126 can be, for example, soldered inside the narrow end of the 2 screen 102 to narrow the opening (i.e., access) to so as to prohibit a siphoning tool from fitting through the screen narrow end 108.

[0028] The tool 100 can be retrofitted to any supply line of the fuel oil using a wrench or similar equipment by an operator. Further, the tool is durable, cost-effective and can be easily used with #2 fuel oil without periodic manual intervention.

[0029] FIG. 2 illustrates a perspective view showing the fuel oil anti-siphoning tool 100 of the present invention in accordance with the disclosed architecture. In use, the tool 100 is assembled with the screen 102 positioned inside the reduced coupling 110 and is held tight (i.e., biased) by the support spring 124. The hexagonal head 122 may be fastened to the supply pipe 303 carrying fuel oil and the bottom end 114 of the reduced coupling 110 may be fastened at the other end to the delivery pipe 302.

[0030] The hex bushing 116 is screwed inside the reduced coupling 110 with the male threads 118 of hex bushing 116 threaded to the female threads 128 of the first fitting side 112 of the reduced coupling 110. The spring 124 is positioned and fastened using the BU FLSH FTGCOP fastener 126. In the preferred embodiment, the length of the tool 100 in an assembled state, as shown in FIG. 2, is about 4 such that the tool 100 can be easily positioned in hard-to-reach areas by an operator.

[0031] FIG. 3 illustrates a perspective view showing the anti-siphoning tool installed in a fuel oil supply line for preventing oil siphoning in accordance with the disclosed architecture. The tool 100 is positioned in the fuel oil supply line, for example between the delivery pipe 302 and the supply pipe 303 to prevent transmission of fuel back from the fuel tank 304. The tool 100 is secured to the supply line by fastening the hexagonal head 122 to the supply pipe 303 and by fastening the second fitting side 114 to the delivery pipe 302.

[0032] The tool 100 can be installed in any new supply line installation or can be retrofitted in any commercial or residential pipeline. Further, the tool 100 may come in different sizes and configuration to meet requirements of different fuel oil volume and pressure.

[0033] FIG. 4 illustrates a flow diagram depicting a process of using the fuel oil anti-siphoning tool of the present invention in accordance with the disclosed architecture. Initially, the screen is positioned inside the reduced coupling and fastened, secured, or biased using the support spring (Step 402). Then, the tool is fastened using a wrench or similar equipment between the delivery pipe and the supply pipe (Step 404). Thereafter, the fuel oil is supplied from the connected fuel tank while preventing siphoning (Step 406).

[0034] Advantageously, the fuel oil anti-siphoning tool 100 can be used for preventing theft of #2 fuel oil from the fuel tank in a simple, convenient, and easy to install theft prevention system. Further, the tool 100 does not require any manual intervention and maintains flow of the fuel from the fuel tank. The #2 oil flows into the second end of the hex bushing 116 through the screen 102 and out of the second end 114 of the reduced coupling 110.
