Filling units for filling small tanks or the like with gasoline, kerosene, or other flowable materials which attach an inlet to such a tank. When the filling unit is in a fill position, a displacer section occupies a substantial volume within the tank. It allows the person filling the tank to supply the liquid until the tank will accept no more and the liquid reaches a predetermined level in a funnel portion of the filler. Thereafter, removal of the displacer section from the tank, as by sliding a section of the overall unit upward, allows the liquid in the funnel to enter the tank and fill the volume evacuated by the displacer section to complete the filling without any spillage. The overall unit may be removed from the tank each filling operation, or it may be designed to include a protective cap that fits over the upward protruding portion of the unit, allowing the unit to remain mounted on the tank.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, FIG. 1 illustrates a boat 22 equipped with a prior art fuel fill fitting 18. During fueling a fuel pump 16 is positioned with its nozzle 14 inserted into the fuel fill fitting 18 on the deck 20 of the boat 22. The fuel flowing through the nozzle 14 is deposited in a fuel line for transport through the fuel line to a fuel tank. As the fuel exits the nozzle 14 and enters the fuel line, the pressure of the fuel entering the fuel line causes fuel to "splash back" towards the fuel fill fitting. Thus, when fuel is pumped, "splash back" of the fuel causes a fuel spill 12 to exit the fuel fill fitting 18 and splash onto a deck 20 of the boat 22.

FIG. 9 illustrates the fuel spill collector device of the present invention incorporated into a fuel line. The fuel spill collector device is indicated generally by the numeral 24 and includes a hollow body 26 having an open top end 28 and an open bottom end 30. The hollow body 26 may be of any useful shape. The cylindrical cup shaped form of the hollow body 26 as is illustrated in the figures is for purposes of example only and not meant to limit the scope of the invention in any manner. The circumference of the open top end 28 and open bottom end 30 may vary based upon the size of the fuel line and fuel fill fitting between which the device is connected and the type of vehicle in which the device 24 is incorporated. Furthermore, the circumference of the open top end 28 and open bottom end 30 need not be equivalent.

The hollow body 26 is illustrated in FIGS. 2 and 4 as a cylindrical cup-shaped housing 40, in which the diameter of the open top end 28 is larger than the diameter of the open bottom end 30. The hollow body 26 will also accommodate any side wall or stringer restrictions. It may be circular and thinner from top to bottom, or thinner, wider and offset. The principle function of the hollow body 26 of the invention applies in almost any type of configuration, when the spout 14 of the fuel pump nozzle 16 is inserted all the way through the hollow body 26.

While a preferred structure and form for the hollow body 26 is shown and described herein, those of ordinary skill in the art who have read this description will appreciate that there are numerous other structures for the hollow body and, therefore, as used herein the phrase "hollow body means for catching splash back of fuel" should be construed as including all such structures as long as they achieve the desired result of catching splash back of fuel, and therefore, that all such alternative mechanisms are to be considered as equivalent to the one described herein.

An entrance flow guide member 34 is positioned at the open top end 28 of the hollow body 26 and is illustrated in FIGS. 2-5. The entrance flow guide member 34 includes of an upper cylindrical collar 42 integral with and extending about the open top end 28 of the hollow body 26. The upper cylindrical collar 42 acts to receive the fuel pump nozzle as it is introduced into the fuel fill fitting 18. The entrance flow guide member 34 is formed to receive and form a sealed fit with a fuel pump nozzle 14 when the fuel pump nozzle 14 is introduced thereto. To form a seal with the fuel pump nozzle 14 a flexible cover may be connected to the upper cylindrical collar 42 having a cross-shaped slit cut therein for receiving a fuel pump nozzle and forming a releasable seal therewith as illustrated in FIGS. 2-6. Alternatively, the seal may be formed using a structure as is illustrated in FIGS. 7 and 8.

While preferred and alternate structures and forms for the entrance flow guide member 34 are shown and described herein, those of ordinary skill in the art who have read this description will appreciate that there are numerous other structures for the entrance flow guide member 34 and, therefore, as used herein the phrase "entrance flow guide member 34 for releasably sealing the fuel pump nozzle within said device" should be construed as including all such structures as long as they achieve the desired result of releasably sealing the fuel pump nozzle within the fuel spill collector device, and therefore, that all such alternative mechanisms are to be considered as equivalent to the one described herein.

The upper cylindrical collar 42 as illustrated in FIG. 4 has an internal ring-shaped groove 44 near its upper edge 46. A disk-shaped flexible cover 48 with a bead 50 about a peripheral edge is carried in an affixed manner within the ring-shaped groove 44. The cover 48 has a cross-shaped slot 52 therethrough for releasably receiving the nozzle 14 of the fuel pump 16.

FIG. 6 illustrates a hollow body 26 in which the diameter of the open top end 28 is larger than the diameter of the open bottom end 30. The open bottom end 30 includes a lower cylindrical collar 38 which is sized to fit into the fuel filler line 36. The entrance flow guide member 34 includes an upper cylindrical collar 72 integral with and extending about the open top end 28 of the hollow body 26. The upper cylindrical collar 72 has an external thread 74 spiraling about an outer side 75 thereof and a cylindrical sleeve 76 is provided including a skirt 77 depending therefrom having a thread 78 spiraling around an inner side 79 thereof. The cylindrical sleeve 76 can thread onto the upper cylindrical collar 72. The cylindrical sleeve 76 further includes an internal ring-shaped groove 80 near its upper edge 82. The disk-shaped flexible cover 48 including the bead 50 about its peripheral edge is carried in an affixed manner within the ring-shaped groove 80. The cover 48 further includes the cross-shaped slot 52 therethrough, to receive the spout 14 of the fuel pump nozzle 16. The entrance flow guide member 34 further includes a deflector plate 90, carried in the hollow body 26 below the open top end 28, to help divert the fuel entering therein.

In FIGS. 7 and 8, the entrance flow guide member 34 includes a cylindrical cap 104, having a central aperture 106 therethrough in lieu of the cross-shaped slot 52. The cap 104 snaps onto the open top end 28 of the hollow body 26. A short tube 108 extends upwardly from the central aperture 106 in the cylindrical cap 104 for receiving the nozzle 14 of the fuel pump 16. The short tube 108 has an internal annular channel 110 thereabout and is sized to receive the nozzle 14 of the fuel pump 16. An O-ring 112 is carried within the annular channel 110 in the short tube 108 near an upper open end 114 thereof providing a releasable seal fit between the nozzle 14 of the fuel pump 16 and the short tube 108. The O-ring 112 aids in preventing fuel coming out of the nozzle 14 from backing out of the short tube 108. The alternative forms for producing the releasable seal between the upper open end 28 and the nozzle 14 of the fuel pump are due to the differing configurations for the fuel filling and fuel line for different types of cars and boats.

A first connecting facility 58 is provided for connecting the upper cylindrical collar 56 to a bottom end of a fuel fill fitting 18 as illustrated in FIG. 5. The first connecting facility 58 includes a flexible tube 62 extending between the bottom end of the fuel fill fitting 18 and the upper cylindrical collar 56. A pair of hose clamps 64 are provided. A first of the pair of hose clamps 63 will seal the flexible tube 62 to the upper cylindrical collar 56 and a second of the pair of hose clamps 64 will seal the flexible tube 62 to the fuel fill fitting connecting the flexible tube 62 between the bottom end of the fuel fill fitting 18 and the upper cylindrical collar 56.

A nozzle receiving member 32 is positioned at the open bottom end 30 of the hollow body 26 for connection to the fuel line 36. The nozzle receiving member 32 is formed as a lower cylindrical collar 38 integral with and extending about the open bottom end 30 of the hollow body 26 as is more clearly illustrated in FIG. 2. The lower cylindrical collar 38 is sized to fit into the fuel filler line 36. A second connecting facility 60 is provided for connecting the lower cylindrical collar 38 to a top end of the fuel filler line 36 and includes a hose clamp 66. The fuel filler line 36 is seated within and connected to the fuel tank 37 via a hose clamp 66 as is illustrated in FIG. 5. A deflector plate 68 is carried in the hollow body 26 below the open top end 28, to help divert the fuel entering therein.

To pump fuel through the fuel filler line 36 for deposit into a fuel tank 37 the nozzle 14 of the fuel pump 16 is inserted into the entrance flow guide member 34 and positioned to extend through the hollow body 26 and into or through the nozzle receiving member 32. A cross-sectional view of the fuel spill collector device 24 connected to the fuel line 36 is illustrated in FIG. 4. The device 24 will prevent the fuel spill 12 by catching a fuel back splash, suppress fumes and greatly decrease fueling time by utilizing venturi and gravitational return effects.

Alternatively, the fuel spill collector device 24 may be connected between the fuel line 36 and fuel fill fitting 18 by welding both the bottom end of the fuel fill fitting 18 to the upper cylindrical collar 56 and the lower cylindrical collar 38 within the top end of the fuel filler line 36 to produce a permanent seal.

The drawings show the device 10 used in the boat 22, in which the fuel fill fitting 18 is mounted into the deck 20. Other motor vehicles, such as automobiles, trucks, vans, motorcycles, etc. can utilize the device 10, to prevent fuel spills. The device may be adapted for use within the fuel line of any vehicle using a liquid fuel and the description and drawings are not meant to limit the application of the present invention.

In operation, the fuel spill collector device 24 is connected between the fuel line 36 and the fuel fill fitting 18. This may be performed by either welding the lower cylindrical collar 38 to the fuel filler line 36 and welding the upper cylindrical collar 56 to the fuel fill fitting 18. Alternatively, the lower cylindrical collar 38 may be inserted within the fuel filler line 36 and securing a clamp 66 therearound to create a pressure fit with the lower cylindrical collar 38. A flexible tube 62 is then connected between the upper cylindrical collar 56 and the fuel fill fitting 18. A first hose clamp 64 will then be secured around the flexible tube 62 at a point through which the fuel fill fitting 18 extends to secure the flexible tube 62 to the fuel fill fitting 18. A second hose clamp is then secured around the flexible tube 62 at a point through which the upper cylindrical collar 56 extends to secure the flexible tube 62 to the upper cylindrical collar 56. The fuel fill fitting 18 is thus secured to the upper cylindrical collar 56 via the flexible tube 62.

The nozzle 14 of the fuel pump 16 is then inserted into the fuel fill fitting 18 so as to extend through the upper cylindrical collar 56 whereby a releasable seal is formed between the nozzle 14 and the cover 48, through the hollow body 26 and into the nozzle receiving member 32. When fuel is pumped through the nozzle 14 it is deposited directly into the fuel line 36 through which it travels for placement in the fuel tank 37. The pressure at which the fuel is pumped into the fuel line 36 causes some fuel to be splashed back towards the nozzle 14 and the fuel fill fitting 18. This fuel splash back is caught by the hollow body 26 and redeposited into the fuel line 36 for transport to the fuel tank 37. The releasable seal formed either between the cover 48 and the nozzle 14 or the O-ring and the nozzle 14 act as a further barrier for the fuel splash back to thereby retain the fuel from exiting the fuel fill fitting 18 and thus preventing a fuel spill.

Once the fuel tank is full or enough fuel has been deposited into the fuel line, the fuel pump nozzle is removed from the fuel spill collector device and the fuel fill fitting is sealed closed. When more fuel must be deposited into the fuel tank, the fuel fill fitting is unsealed and the process of inserting the nozzle and depositing fuel into the fuel line is repeated.
