FILLING NECK AND ANTITHEFT ASSEMBLY FOR GAS TANKS 2 Sheets-Sheet 2 Filed Jan. 21, 1936 Patented Sept. 1, 1936 UNITED STATES PATENT OFFICE FILLING NECK AND ANTITHEFT ASSEBIBLY FOR GAS TANKS 1 Claim.

This invention relates broadly to gas tanks and more particularly to tanks forming part of an automobile equipment for carrying gasoline.

The invention is particularly concerned with 5 means for preventing theft, by siphoning, or

otherwise from such tanks.

Briefly the invention consists in an assembly of parts which may be readily applied to the gas tank and which includes a filling neck for the 10 tank together with means for efiectively preventing the siphoning of gasoline from the tank through said neck.

The invention together with its objects and advantages will be best understood from a study {of the following description taken in connection with the accompanying drawings wherein:

Figure 1 is an elevational view of the neck and anti-theft assembly, and illustrating an application of the same to a tank, a portion of which is 20 shown in section.

Figure 2 is a longitudinal sectional view taken substantially on line 2-2 of Figure 1.

Figure 3 is a top plan view with the cap removed.

25 Figure 4 is a fragmentary elevational view of the upper portion of the anti-theft cylinder.

Figure 5 is a top plan view of an anti-splash ,collar and Figure 6 is a side elevational view thereof.

30 Referring more in detail to the drawings it will be seen that in accordance with the present invention, and in the preferred embodiment thereof, there is provided a cylindrical filling neck 5 for use with a gasoline tank a. portion of which 35 is shown in the drawings and indicated by the reference numeral 6.

At its base or lower end the neck 5 is provided with an outstanding annular attaching flange 1 formed with slots 8.

40 The neck 5 is also externally threaded and is adapted to have screwed thereon as at 9 a suitable closure cap I0.

Further the invention comprises an anti-theft cylinder II which at its upper edge has formed integral therewith upstanding lugs I2 having reduced terminals to provide bendable fingers I3 and shoulders I4 at the junction of the fingers I3 with the lugs I2.

Further the invention comprises an anti-splash cylinder I5 which has projecting from its upper edge spaced flanges I6 formed with slots I1.

Further in accordance with the present invention the top of the gasoline tank 6 is provided 55 with a filling opening 20 and inwardly from said ogening the top of the tank is provided with slots In assembling the parts herein described in detail the base flange I of the neck rests on the top of the tank 6 with the slots 8 in the flange 5 in registry with the slots I9 in the top of the tank 6.

The splash cylinder I5 is disposed concentric to the opening 20 and has its flanges I6 disposed against the inner side of the top of the tank with 10 the openings II in the flanges in registry with the openings I9.

The anti-theft cylinder II is disposed within the tank and the fingers I3 are passed upwardly through the alined slots or openings 8, I9 and I1 as shown in Figure 2 and then clinched as also shown in Figure 2 to hold the parts in the assembled relaticn shown in said figure. In this connection it will be understood that the assemblage will take place during the construction of the tank 6.

With the parts assembled as shown in Figure 2 it will be noted that shoulders I4 together with the lugs I2 will serve to space the upper edge of the anti-theft cylinder downwardly from the top of the tank 6 so that the gasoline entering the cylinder II will overflow through the space between the upper edge of the cylinder II and the top of the tank 6 into the tank for filling the same.

The manner of filling the tank is thought to be obvious, the gasoline being introduced through the neck I5 and the anti-splash cylinder I5 into the cylinder II tooverflow the cylinder into the tank, cylinder I5 serving not only to prevent splashing of the fluid as it is being introduced into the gasoline tank, but said cylinder will also serve to effectively prevent the passage of any element into the tank 6 as might be efiectually used for siphoning the gasoline contents from the tank.

It is understood that after the fingers I3 have been clinched as shown in Figure 2 said fingers may be riveted, spot-welded or otherwise secured so as to prevent any dismantling of the parts.

Having thus described the invention, what is claimed as new is:

In combination with a gasoline tank having a wall provided with a filling opening and a series of slots disposed about said opening and spaced inwardly from the edge thereof; a filling neck having a base flange resting on the outer face of said wall, and having openings in said flange registering with the first named openings, and an anti-theft cylinder disposed within said tank and having an open end, and also having lugs projecting longitudinally from the peripheral wall of said anti-theft cylinder at the open end thereof, said lugs having reduced ends extending through the aforementioned openings in the tank wall and flange of said neck and clinched to secure said neck and anti-theft cylinder in fixed position relative to said wall, with said lugs serving to space the open end of the anti-theft cylinder from said tank wall, an anti-splash, rela- 2' a ,v I 2,052,782

tively short cylinder disposed concentric to said filling opening and provided at one end with outstanding flanges provided with slots registering with the first named openings and through which said slots the aforementioned lugs also extend for securing said anti-splash cylinder in fixed position relative to the aforementioned parts.
