Patente lf 30, 1930 THOMAS H'U'GHES, OF RAWLINS, WYOMING THEFT-PREVENTING ATTACHMENT FOR TANKS Application flled January 17, 1929. Serial No. 333,101.

This invention relates to theft preventing attachments for vtanks, and more particularly to a device for preventing the theft of gasoline from the tanks of automobiles.

An important obj ect of the invention is to produce a device of this character which may be readily modified in its construction to permit its adaptation to tanks of different characters, which may be installed in the tank with a minimum of efiort and will, upon installation, be locked within the tank, so that it may not be removed therefrom, and W-hich may be very readily .and cheaply manufactured.

A further and more specific object of the invention is to provide a member which may be inserted in the filling neck of a tank and which, when inserted 'provides in said filling neck a sharply reverted entrance channel which, because of its structure, prevents lthe insertion of fiexible tubes or the like, by means of which the contents vof the tank mi ht be siphoned therefrom.

still further object of the invention is to provide a device of this character which, by its application, provides a Splash guard, preventing loss of the contents of the tank in event the filling cap becomes lost or is stolen.

These and other objects I attain by the construction shown in the accompanying drawing, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein Figure 1 is a sectional View through a tank, a theft preventing device constructed in accordance with my invention being shown in osition therein;

igure 2 is a Vertical sectional view through the theft preventing device;

F igure 3 is a sectional view illustrating the device in position in a different form of tank inlet.

Referring now more particularly to the drawing, the numeral 10 generally designa-tes a tube closed at its lower end, as indicated at 11, and having an open top 12 provided with an out-turned flange 13. This tube is of a size to enter the fillmg openlng 14 of the tank and the flange is of a size permitting it to seat upon the lower wall 15 of the threaded recess provided for the reception of the cap 16. In the illustration of Figure 1, the filling neck 1s in 'the form of a simple casting 17 secured directly to the tank wall 18 and the mounting Just described is employed with such structures. Some tanks are provided with filling 'necks 19, the outer ends of which are exteriorly threaded for engagement by the cap 20. With such a structure, the flange 13 of the tube will seat against the outer end of the filling tube.

At one side and intermediate its ends, the tube 11 is formed with an opening 21 and a partition 22 extends from the upper end of the tube and above this opening downwardly through the tube and has its lower end spaced from the bottom wall of the casing to provide communication between the

Channels

23 and 24 formed in the casing by the partition. The Channels 23 and 24 really constitute a single channel, the inlet end of which is the open mouth 12 of the tube and the outlet end of which is the opening 21. This channel beingsharply reverted will prevent the passage of a fiexible tube inserted for the purpose of siphoning out the contents of the tank and, at the same time, the tube will act as a Splash preventer in event the cap 16 or 20 is removed.

Some suitable means is provided to lock the tube in position within the tank. This means may comprise springs 25 yielding to permit passage of the tube through the filling opening and then springing outwardly to engage beneath a shoulder 26 produced therein. vThe positioning of these Springs will, of course, depend upon the type of opening in which the tube is to be disposed. In some cases, the tube 10 will not extend entirely into the tank but will be disposed within the filling neck thereof unless it is ,made of abnormal length, and in order to prevent the necessity for this, the wall of the tube from the opening 21 to its bottom is formed With a groove 27 which Will permit passage of fluid from this opening to the exterior of the bottom of the tube. Breather openings 28 are formed in the tube adjacent the upper end thereof to permit passage of air and gases to the vent opening 29 of the cap.

Since the lconstruction employed is capable of a certain range of change and modification without materially departing from the spirit of the invention, I do not limit myself to such specific structure except as hereinafter claimed.

I claim '1. An anti-theft attachment for gasoline storage tanks ofv automobiles and the like comprising a tube having a closed inner end 4adapted tobe inserted in and locked inposition in the filling opening of the tank, the wall of the tube having an opening form'ed therein intermediate its ends, -and a partition extending from one' side of the tube adjacent the top thereof downwardly through said tube to a point adjacentI the bottom thereof and preventin g access to said opening throu h the open end of the tube.

'2. n anti-theft attachment for gasoline storage tanks of automobiles and the like comprising a tube having a closed inner end adapted tobe inserted in and locked in position in the filling opening of the tank, the

, wall of the tube havmg an opening formed therein intermediate its ends, 'and a partition extending from one side of the tube adj acent the top thereof downwardly through said tube to a point adjacent the bottom thereof and preventing access to said opening through the open end of the tube, the wall of the tube from said opening to the closed end thereof having a groove formed in its exterior.

3. The combination With a tank having a filling opening, of an externally straight tube extending into the tank from the filling opening and closed at its lower end and having a tortuous channel communicating at one end With the filling opening and the tank and communicating at its opposite end With the i tank at a point near said opening, the channel being imperforate between its ends.

In testimony Whereof I hereunto afix my signature.

THOMAS W. HUGH'ES.
