, residing at Dayton, county of Montgomery', and State of Ohio, have invented certain.

new and useful Improvements in Fuel-Supply Reservoirs for Internal-Combustion Engines, ofvwhich the following is a full, clear,

and exact description.-

The present mvention relates to liquid containers and has among its objects to provide a container with means for varying the extent to which a liquid can be introduced into lit before overflowing at the filler-openlng. i L

Other and further objects of the present invention will be apparent from the following description, reference being had to the accompanying drawings, wherein preferred embodiments Vof the vpresent invention are clearly shown:

In Kthe drawings:

Fig. 1 is a view partlyin section showing a vessel embodyingthe present invention adapted for use as a fuel tank for an internal-combustion engine; and

Fia'. 2 is a view partlyin section of a modified form thereof.

The present invention contemplates broadly'the provision of avessel having a filler opening, means for preventing the escape of air from the vessel after a certain amount of liquid has been introduced in order to limit the extent to which .liquid can be introduced before overflowing ,at the filler opening, and means for changing the air trapping capacity of the vessel.

Referring to Fig. 1, 2O is an engine to Vwhich is connected' a fuel inlet pipe 2l.

Pipe 21 extends into a tank 22, the opening in the tank through which the pipe extends is sealed by any suitable coupling'23.

Tank 22 has an annular flange 24 depending from the topwall of the tank toward the bottom wall thereof. Flange 24 provides a filler opening or passage 25- extending from thinterior of the tank to the atmosphere. Passage 25 is provided with a cover 26 having a small air vent 27 and is pivotally mounted upon a bolt 28.

A screw 29 is `provided in the top wall of the tank 22 and is adapted to closejan opening leading from the interior 'of the tank.

r)he fuel for the internal-combustion engine is poured into the tank through the passsage 25. As the fuel is 4being I poured into said tank air will be pushed out through the passage 25. When the fuel rises slightly above the lower edge 31 of the 'flange 24 said fuel will seal the lower end ofthe passage 25' and prevent thefurther escape l of air from the ltank 22.

In thismanner an air .pocket is formed in the upper part of the tank 22 this pocket belng bounded by the liquid'level, the side and top walls of the vtank and the `outer lWall of flange 25. After the lower edge 31 of the flangel 24 is covered,but"little more fuel can be poured into the tank 22 in addition to that' amount which thepassage 25 sure within thetank. v

If it is desirable to fill the` tank 22. completely with fuel, the screw 29 is withdrawn is adapted to hold `because of the air preswhereby the air, instead of kbeing pocketed in the upper part of tank 22, can escape through the opening 30. In this manner the air trapping capacity of the tank is decreased and itsliquid containing capacity increased.

Thentility of this device will be apparent when considering its application as a fuel. tank for an internal-combustion engine and particularly to that type of internal-combustion engine which is used for drivingl a generating unit for charging storage batteries. In the sale of battery charging plants it vmay be desirable to provide one type of plant for charging batteries of various capacities. For example, a certain plant could be used to charge an 8O ampere hou-r battery or a 160 amperehour battery. lf the tank 22 is constructed to contain enough fuel when completely .filled 'to operatethe engine long enough to charge the 160 ampere hour battery, the screw 29 is omitted. Therefore the total fuel capacity of the tank 22 serves as a measure ofthe duration of engine operatiop. But if the plant is sold with an 80 ampere hour battery the screw 29 is permitted to remain in the position shown. The length of the flange 24 is such as to make the fuel capacity of the tank approximately one half what it would be if the screw 29 were removed. Therefore it is only necessary to instruct the attendant to fill the tank to overflowing when the batteries need charging to bring the batteries up to full charge. The air trap will limit the operation of the engine to the llO llCl

charge periodl when the smallv battery is used.: VThe .modiati'on'shown inv Fig-.i2 shows a tank in which the capacity thereofycanlbe \'f aried to any/suitable degree. this the tank isl 'screvvthr'eaded tohrecei'v 35 to provide i edge thereof Mfiiv'll "move vertically" upvva'd to decrease tank` ndg' to increaseits'liquid containing 'capaci y; .Sleeve 85T canbe looked intoaan position 4.by lmeans of ai lock nut 3362;` f 'n ,e/While; theI `form of mechanism herein .shown and described constitutes a preferred embodiment otone form of invention, it is,

-to be lunderstood that other lforms might bel adoptedand various changes and alterations made in the shape, Size, and proportion of the elements therein without departing from the spirit and scope of theinvention.
