' To aZZwhom tt may concern.' v

lBe it known that I, FREDERICK C. Cosne, a citizen of the United States, residing at Columbus, in the county of' Franklin and State of Ohio', have invented certainnew and useful Improvementsin Liquid-Fuel Tanks, of which the following is a specification, reference being had therein to4 the accompanying drawing. n

The invention relates to fuel tanks of the sort adapted for use on vehicles the motors of which receive theirr energy from liquid fuel. The fuel may be used either in amotor of lthe internalcombustion type oriunder a boiler to generate steam.

flhe principalf'ob3e'ct of-the invention is te provide a tank having discharge connections arranged to insure the retention .of a reserve -supplv of fuel which canbe releasedonly by the action of the operator.

Another obgect 1s to provide automatic means for positively preventing thefllingg 9,'-butwh1ch has suicient jbuoyancy'when of the tank above -a certain predetermined level.. 'i .25-n

A fuel tank embodyin especially well adapted'L or use'fin connectionwith gasolene locomotivesv intended for use in and about mines..` As is wellknown there is great .danger in mines, especially .cc'al mines, of explosions resulting from the 'ignitionof aA gaseous or dusty atmosphere.v

On accountof this'danger' of explosion it is essential thatthe gasolene tank of the locomotive beilled. outside-.of the mine. If 'it were filled inside there would be great dan'- `,ger of the resulting gasolene vapors becommg ignited .and setting firel to the explosive By means of a device sufficient gasolene .in his reserve supply` to make the run tothe filling stationoutside ofthe mine.

Of the drawing-Figure 1 is a cross-sectional view through a fuel tank embodying `one form of my invention. Fig. 2 is a cross-sectional view through a. fue] tank embodying another form of'my invention. Referring to Fig. 1 of the drawing, l repthe,

my `invention is,

resents as a whole the main body of the tank, which may be formed of sheet metal as f shown, or in any other desired way. In the top wall of the tanky there is an aperture which `is `mounted a' frame 2 secured inplace by rivets 3. To the frame 2 rthere isbolted a plate 4 having a-threaded aperture 5 into i which is. screwed the enjd ofthe fillingfppe 6'. At thelower side of the plate 4 there is a large threaded recess which-registers with the apertureA 5. At-the inner side of vthis recess there is a strainery 7 which is held.

inl place by a threaded ring; 8 having at' its lower side an inward projectingI annularv ange. Positioned within'the ring 8 and above the horizontal iange thereof is a valve closure 9 having a depending stem 10. Pivf vwhich is suiiicient to liftgthe valvev closure immersedl in the;v liquid fuel to press the 'valve closure closely against the fiangeof the" ring Sto cut off' the passage through the aperture and the pipe Formed at the upper side ofthe plate4 is la vent chamber 14 which is closed at the top by means of a valve 15 whichV has depending slotted and serves to' limit the movementl of the guide fingers 16. A Cotter pin 16?? passes through the slots of the guide fingers. r

valve. `This'valve has suflicient weight-te...

close' the vent against the admission of air and dust but not enoughto interfere with the outward flow of air during the fillingof the tank. l v

In the bottom wall of theta-nk there isfan aperture in which is mounted a flange 17 held in place by rivets 17, Securedl to this yflange 17is a plate 18 provided with twoi i threaded'

apertures

19 and 20.' Into these

apertures

19 and 20

thereare ittedpipes

21 and 22 which connect by means of a. two- -way lvalve 23 with a pipe 24 which leads to l i,

the carburetor or other device for utilizin the fuel. It will be seen `that by means of .i the valve 23 either of the

pipes

21 and 22 may be connected with the pipe 24. One ofthe apertures in the plate 18, as for instance 19, extends upward through a boss 25I l`-'so that its upper end is at a level considerably above the upper end of the other aperture 20. At the upper end of the aperture 20 there is provided a valve needle 26 which is adapted to entirely close the aperture.- Pivotally connected to the upper end of the needle 26 is a lever 27 which is pivoted at 28 to the plate 18. The other end of the lever 27 carries a float 29. When the tank is partially filled the buoyancy of the float 29 serves to force the needle 26 downward to entirely cut ofl' the passage through the aperture 20. However, when the level of liquid in the tank falls belowa certain level,the float assumes a position suchthat the needle 26 is held away from its seat `and the aperture 20 is opened.

. In operation, when it is desired to fill the tank the operator simplypours gasolene or other fuel into the funnel from which it flows through the pipe 6 and the aperture 5 around the valve closure 9 into the tank, it being understood that the valve closure is held off from its seat by the float 13. However, as soon as the tank becomes filled the fioa-t 13 is elevated and the valve closure 9 is drawn down against its seat and the further flow of liquid into the tank is prevented. Because of this automatic valve it is impossible for the operator to flood or overflow the tank. During the filling operation, the air inthe tank can freely pass out under the valve 15. However, this valve is normally held closed by its own weight and prevents the flow into the tank of air or dust. When the tank is filled the float 29 holds the needle 26 in position to close the aperture 20. Therefore, in order to get a flow of fuel to the carbureter the valve 23 must be set to provide communication through the pipe-21. The fuel flows out through the pipe 21 until the level in the tank is lowered to the upper end of the aperture 19. When this level has been reached the float 29 will have been lowered to such an extent that the needle 26 will. have been lifted from its seat, thus opening the aperture 20. As soon as there is a failure of gasolene to flow through the aperture 19 and the pipe 21 the operator simply'turns the valve 23 to make connection with the pipe 22. The gasolene in the tank below the level of the upper end of the aperture 19 then becomes available and this is sufficient to enable the locomotive or other vehicle to run to a place Where thetank can be refilled. It will be observed that upon refilling, the float 29 again closes the aperture 20, thus making it absolutely necessary for the operator to again turn the valve 23 to connectI the pipe 21 with the pipe 24.

In Fig. 2 I have shown a modified form of my invention. In this view I have shown a tank having a partition 30 which divides the tank into two unequal parts Eiland 32.

pipe 21.

The pipe 21 communicates with the larger part 31, and the pipe 22 with the smaller part 32, each pipe preferably terminating at the bottomof the tank. The valve needle 26 for the pipe 22 is controlled by the float 29a which is located in the part 31 of the tank. The float 29a may be connected with the valve needle 26 by means of the lever 27a pivoted to the partition 30 at 28u and connected with the valve needle by means of the link 27h.

It will be clear thatl the operation of the device as shown in Fig. 2 is substantially the same as that of the device shown in Fig. 1. The valve 26 is-held closed so long as there is a supply of fuel in the part of the tank with which the pipe 21 communicates. It is only .after the fuel in this part of the tank has been exhausted or nearly exhausted that an fuel can be drawn from the part of the tanli with which the pipe 22 communicates. The operator, therefore, must after-fillingthe tank turn the valve 23 to cut off the pipe 22 and connect the pipe 21 before he can get any flow of fuel to his carbureter. After the supply in the part 31 is exhausted thenthe supply in the part 32 can be made available by throwing the valve 23 to connect the pipe 22 and disconnect the I am aware that it has been before pro posed to provide a reserve supply of liquid fuel which can be used by throwing a valve, but in all of the earlier devices with which I am familiar, it has been possible for the operator, either carelessly or intentionally, to leave the valves so positioned that the supposed reserve supply is used either before or simultaneously with the main supply. In the device embodying my invention, however, the automatic needle valve 26 prevents the use of the reserve' supply until the main supply has been entirely exhausted.

What I claim is:

1. In a device for containing and supplying liquid fuel, the combination of a fuel container, a' discharge duct communicating with the container at one oint, a second discharge duct communicating with the container at another point, means for preventing a part of the fuel in the container from flowing out through the first duct, a manually controllable valve for connecting either duct with an outlet pipe, and a valve controlled by the level of the fuel in the container for closing the second duct so long as there is sufficient fuel toflow out through the first duct and for opening the second duct when the supply of fuel which can flow out through the .first duct is exhausted.

2. In a device for containing and supplying liquid fuel, the combination of a tank, two discharge ducts communicating with -the tanklat different levels, a manually conlll@ trollable valve for connecting either duct In testimony whereof ax my signawith an outlet pipe, and a valve automatiture, in presence of two witnesses. cally controlled by the level of the fuel in the tank for closing the lower duct when the 5 fuel level is above the opening to the upperv Witnesses: l duct and for opening the lower duct when ALEX.
