VALVE.

Application filed November 26, 1920. Serial No. 426,527..

ple and improved construction, whereby a reserve supply of liquid is made available for use when the main supply in the tank has been exhausted.

In the accompanying drawing, Fig. 1 is a vertical sectional view of a portion of a gasoline tank having an improved reserve supply valve constructed in accordance with my invention; and Fig. 2 is a vertical sectional view similar to Fig. 1 showing the valve in position to utilize the reserve supply of gasoline.

In the drawing, the numeral 2 designates a gasoline tank which may suitably be the ordinary feed tank of an automobile. In the bottom of the tank 2 is formed a boss 3 which is screw-threaded to receive the threaded upper end of a fixed T-shaped outlet tube 4 having a branch connection 5 screw-threaded at 6 for attachment-to the usual gasoline supply line. The lower end of the outlet tube 4 is screw-threaded at 7 to receive a cap 8 within which is a suitable packing ring 9 which prevents the escape of liquid from the lower end of the tube 4.

A tube 10 of proper diameter to fit tightly but slidably within the fixed tube 4 extends through the tube 4 and into the tank 2, and carries at its lower end a stop cock 11. The tube 10 also carries a stop member 12, suitably a disc or washer, which limits the downward movement of the tube 10. Just below the stop member12 the tube 10 is provided with an opening 13 and below the opening 13 is another and longer opening 14 which communicates with the branch connection 5. It will be observed that the opening 14 communicates with the branch 5 in all positions of the tube 10. V

In the normal operation of the gasoline tank the valve is inthe position shown in in Fig. 1. The gasoline enters the upper end of the tube 10 and thence passes through the opening 14 and the branch 5. The portion of the tube 10 below the opening 14 serves as a trap for sediment, which may be removed from time to time through the stop cook 11. The stop cock also provides convenient means for drawing off a part or all of the gasoline from the tank. V

WVhen the levelof the gasoline in the tank descends to the level of the upper end of the tube 10 it will cease to flow and warning will thus be given that the tank is nearly empty. In order to make use of the reserve supply of gasoline the tube 10 is pushed up into the position shownin Fig. 2. The gasoline then enters through the opening 13 and passes outthrough the opening 14 and the branch 5 as before, the elongated shape of the opening 14, keeping the tube in communication with the branch 5.

As shown, the opening 13 in the upper position of the valve as shown in Fig. 2, is slightly above the bottom of the tank'2.

Thus when the reserve supply of gasoline is 7 almost exhausted the flow will again stop, but a small amount of gasoline will still remain in the tank and may be made avail able by pulling out the tube 10 slightly, so as to lower the opening 13 without drawing it down below the bottom of the tank. I thus provide for warning the driver of the automobile at two separate times of the fact that his tank is nearly empty. While I have shown and described a preferred embodiment of'my invention, it is to be understood that various changes may be made and that my invention is limited only by the scope of the appended claims.

I claim as my invention I 1. A valve for liquid receptacles comprising a tubular member'having a lateral outlet, a tube mounted slidably within the said tubular member and having both ends extending beyond the said member, and means for limiting the sliding movement of the said inner tube, the said inner tube being provlded with two openings, one of the said openings being in constant communication and provided with a lateral outlet, a tube cured to the lower end of the said inner tube, the said inner tube being provided with two openings, one of the said openings being disposed adjacent to the said said stop member and the other said opening being disposed below the said first named opening and in communication with the said lateral outlet.

3. A valve for liquid receptacles comprising a tubular member adapted to be screwthreaded into the bottom of a tank and provided with a lateral outlet, a tube slidprovided with two openings, one of the said openings being disposed adjacent to the said stop member and the other said opening being of elongated form and in constant communication with the said branch outlet.

4. The combination with a gasoline tank, and a chambered supply pipe coupling connected into and communicating with the bottom of said tank, of a supply pipe section mounted in and adjustable endwise through said coupling with its upper end projecting into said tank and its lower end extending below said coupling, said supply pipe section having a lateral port communicating with the chamber of said coupling, and a drain valve in the lower end of said supply pipe section. I

In testimony whereof, I the said WILLIAM H. MORRIS have hereunto set my hand.
