GAS TANK Filed Nov. 15, 1955 P atented May 14, 1935 UNITED STATE PATENT 1 Claim.

This invention relates to fuel tanks for motor vehicles and more particularly to a sediment trap for catching foreign matter and preventing the latter from passing out with the fuel or returning to the main supply within the tank and has for the primary object the provision of 'a device of the above stated character which may be easily and quickly opened and partially removed from the tank for cleaning and which also provides a cutofi or valve between the trap and the tank.

With these and other objects in view this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

- For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a vertical sectional view illustrating a fuel tank with my invention applied thereto.

Figure 2 is a fragmentary sectional view illustrating a combined valve and strainer between the interiors of the fuel tank and the trap.

Referring in detail to the drawing, the 'numeral I indicates a fuel tank the top wall of which is provided with a filling neck 2 closed by a removable cap 3. The bottom wall of the tank directly under the filling neck is offset, as shown at I, and apertm'ed and has mounted" in the aperture an internally threaded bushing 5, the upper face of which is beveled to form a valve seat 6. Located under the aperture of the tank .and formed integrally with the latter is a bowlshaped receptacle 5' forming a sedimenttrap. The receptacle 5' above its bottom wall is apertured to receive a fitting 6' adapted for connecting an outlet pipe 8 to the receptacle. An opening 9 is formed in the bottom wall of the recep- 'tacle 5 directly under the opening in the tank I and has mounted therein an internally threaded bushing I0 to receive a flanged closure plug II. Interposed between the inner end of the plug II and the bushing 5-is a perforated cylinder I2 to form a screen through which the fuel of the tank must pass before entering the trap or receptacle 5'. The inner endof the plug II is reduced, as shown at I3, to snugly fit within the end of the cylinder and thereby maintains the latter in proper position to align with the opening through the bushing 5.

A valve element I4, consisting of a head I5 3 and a cylindrical portion I6 is externally threaded to be threaded in the opening of the bushing and extends above and below said bushing. The cylindrical portion I6 has apertures I'I and slots I8 extending from said apertures through the lower end of the cylindrical portion I6. An expander I9 is threaded into the lower end of the cylindrical portion' I6 and when properly adjusted will wedge the slotted end of the cylindrical portion against the walls of the opening in the bushing 5. The head I5 is beveled, as shown at 20, and also carries an apertured lug 2| disposed in alignment with the filling neck 2 of the tank I. The normal position of the valve I4 is with the apertures I'I disposed above the bushing 5 so that the fuel within the tank may enter said apertures and pass through the expanderand then through the screen into the trap, the foreign matter which may be within the fuel of the tank will be caught by the screen and prevented from entering the trap. Should it be desired to turn off the fuel of the tank tothe trap, a suitable tool may be inserted through the filling neck and contacted with the aperture of the lug and then rotated to position the apertures I'I below the upper surface of the bushing 5 or to be confined entirely within the walls of the opening of the bushing. The expander prevents the entire removal of the valve from the bushing 5 when turned in a direction to establish communication between the tank and the trap. The removal of the plug I I permits the foreign matter caught by the screen to be easily removed and also it is -to be noted that when the plug I I is removed from the bushing I0 the screen I2 may also be withdrawn along with the plug, consequently permitting the screen to be easily cleaned.

Having described the invention, I claim:

A sediment trap including spaced trap walls having aligned inlet and cleanout openings, internally threaded bushings mounted in said openings, a valve seat formed on the bushing of the inlet opening, a cleanout plug threaded to the bushing of the cleanout opening and having a reduced portion defining a seat, a perforated sleeve engaging said seat at one end with the reduced portion of the plug projecting therein and having its opposite end abutting the bushing of the inlet opening, an external and internal threaded valve sleeve threaded in the bushing of the inlet opening and having one end closed and tapered to form a valve element for cooperation with the valve seat, said valve sleeve having openings adjacent the closed end thereof and provided with slots opening outwardly through the open end thereof, and an apertured expanding plug threaded'into the open end of the valve sleeve.
