\ 3 Claims.

This invention relates to funnels such as may be used for filling automobile tanks with motor fuel.

' One object of the invention is to provide a funnel of the character described which will retain the motor fuel, displaced by air and vapors within the gasoline tank and fill-pipe thereof, until such time as the air and vapors have had a chance to escape and allow the fuel within the funnel to flow into the tank.

Another object of the invention is to provide a funnel of the character described which seals the mouth of the fuel-tank opening to prevent leakage of overflow between said funnel and said tank opening.

Another object of the invention is to provide a funnel of the character described which is adapted to be quickly removably attached to the bayonet joint attaching means provided for the usual automobile tank closing cap.

Another object of the invention is to provide a funnel construction comprising a body portion of soft, flexible material.

These and other objects are attained by means of the apparatus illustrated in the accompanying drawings and described below. It is to be understood that the invention is not limited to the specific form thereof shown and described.

Of the accompanying drawings:

Figure 1 is an elevational view, partly broken away and in section, of a funnel embodying the invention.

Figure 2 is a cross-section taken on the line 2-2 of Figure 1.

Figure 3 is a cross-section taken on the line 33 of Figure 1.

Figure 4 is an elevational view, partly broken away and in section of another embodiment of the invention.

Figure 5 is a cross-section, on a reduced scale, taken on the line 55 of Figure 4.

Figure 6 is an elevational view of another embodiment of the invention.

Figure '7 is a fragmentary elevational view, partly broken away and in section, of still another embodiment of the invention.

Referring to Figures 1, 2, and 3 of the drawings, I0 is a funnel having an enlarged receptacle H, which may be of suitable natural or synthetic rubber or rubber and fabric construction, and which may have a downwardly extending sleeve I2 on its lower end provided with a flange I3 thereon. The flange l3 preferably has a sealing gasket 13 thereunder for sealing the filling openpin H, the latter may have attached thereto an 10 I upwardly extending pin ll adapted to be received through'an opening I8 in a cross-bar H], which is attached to the funnel; l 0. The free end of the pin ll is threaded to receive a wingnut l'l In practical use of the funnel shown in Figures l, 2, and'3, the'wing-nut I! is first released to provide sufiicient space between the flange l3 and pin l 2, so that the ends of the pin I! may be engaged with the bayonet connection provided 2 for the usual tank closing cap'of an automobile having suitable bayonet slots ll, l1".- This is done and the funnel is given about a quarter turn. This engages the pm- IT under the usual lip at the fill-pipe opening 14. A tight seal at the opening of the fill-pipe I5 is obtained by turning the wing-nut I I to urge the flange I3 and gasket l3 against the lip of the fill-pipe IS. The complete seal thus obtained pre'ventsleakage of fuel from the funnel 'receptaclememberlI, which 30 may rise therein due to the pressure of air and vapors in the fuel tank, until such time as the air and vapors have had time, to, escapeup through the fuel in the funnel, thereby allowing the fuel in the funnel member 13 to flow into the fuel tank. In this manner it is possible to completely fill the fuel tank without spilling the fuel.

Referring to Figures 4 and 5 of the drawings,

20 may be an exteriorly threaded sleeve having a pair of oppositely disposed bayonet pins 2|, 2| 40 fixed at one end thereof. At the opposite end of the sleeve 20 there may be secured a funnel member 23, having an opening 23 at the outer end thereof, of sufiicient size to receive nozzle of an ordinary fuel dispensing hose. The member 23 5 may be of more or less flexible vulcanized synthetic rubber to withstand deterioration by the fuel being poured into the fuel tank, and may be vulcanized integral with the sleeve 20, or it may be formed from any other suitable material in 50 any desired shape.

Intermediate. the pins 2|, 2! and the funnel member 23 there may be an interiorly threaded nut 24 adapted to be turned on the threads of the sleeve 20. A suitable gasket 26 may be provided 55 for making a tight seal of the funnel on the lip 21 of the fill-pipe 28 of the fuel tank (not shown).

In the practical use of the funnel shown in Figures 4 and 5 the pins 2|, 2| are inserted in bayonet slots 30, 30 in the lip 21, 21 of the fillpipe 28, and given a quarter turn, then the nut 24 is turned in the proper direction to clamp the funnel on the fill-pipe. The gasket 26 prevents leakage of fuel, from the funnel member 23, which may rise therein due to the pressure of air and vapors in the fuel tank.

Figure 6 illustrates the use of a modified form of the invention disclosed in Figures 4 and 5. The elements are essentially the same as before with the exception that the sleeve 2|] is disposed angularly of the outer neck of the fill-pipe 28. This type takes care of the situation where the fill-pipe opening is located in a substantially vertical position, such as in the back panel of an automobile or the vertical wall of an automobile trunk.

Referring to the modification illustrated in Figure 7, a sleeve 3! is provided with bayonet pins 32 at one end as before. The pressure necessary to maintain the required seal against leakage, and to hold the funnel securely in proper position for use, is obtained by insertion of a strong spring 33 between an annular flange 34, integral with thesleeve 3|, and a slidable washer 35 having a gasket 36 thereunder. The funnel element 36 may be secured to the sleeve 3| as before and, where vulcanized rubber or synthetic rubber is used, may be provided with one or more layers of reinforcing fabric 31.

The apparatus shown in Figure '7 may be quick- 1y secured in firm upright position by inserting pins 32, 32 in the bayonet slots in the fill-pipe, against the tension of the spring 33, and then turning the sleeve 3| about a quarter revolution. The tension of the spring 33 against the washer 35 will cause a tight seal to be made between the fill-pipe opening and the funnel unit, thereby preventing leakage of fuel at that point. The funnel unit may be just as easily removed by simply turning the pins 3 2, 32 back until they coincide with the slots 30, 30 in the neck of the fill-pipe.

The funnel members ll, 23, and 36, being of more or less soft, flexible material like rubber or synthetic rubber will not mar a part of an automobile with which they might come in contact and also will flex about a part of an automobile to accommodate the funnel to more or less inaccessible fill-pipe opening.
