With my fuel filler can A I provide a cylindrical tank body portion I closed at its lower end by the cylindrical bottom portion II'.' A

cylindrical top portion I2 is secured to the upper."

edge of the body portion III. A pressure relief valve I3 is secured to the cylindrical top portion I2 for releasing pressure built up within the body portion). A metaldischarge pipe I5 extends from the upper surface of the top portion I2 downwardly into the tank portion II] to a point just: .abovethe bottom I I thereof. Attached to the upperend. of the discharge pipe I5 is a length of :flexible'hose'or tubing I6 which may be coiled on thetop surface of the top portion I2 as illustrated in Figures 2 and 3. The filler hose I6 is provided with a shutoff valve I'l secured to the end thereof.

The. pump unit B is located centrally of the top portion ;I2 and is composed of a cylindrical base 'portion,l8. which is secured to the top portion l2 at Iil Thecylindrical cup-like member is adapted to be screwed into the cylindrical base portion I8 and the top portion of which is provided with the irregularly outlined lug receiving holes 2 I.; Secured Within the cup-like member:20 is a collar 22 which is adapted to position the elongatedcylinder casing 23 together with the washer 24. The pump unit B is further composed of the plunger 25 which is adapted to operate within the cylinder casing 23 and will force air downwardly and outwardly through the. valve 26 which is composed of the washer 21, the retainer 28 and the spring 29. As pressure is directed against the washer 21 it moves downwardly allowing air to'be forced downward through the opening 30 as a result of the action of the plunger 25 moving downwardly in the cylindrical casing 23, As air is, forced past the valve 26 and intothe cylindrical tank body Ill, the pressure then exerted on the fuel within the body portion I0 will force fuel upwardly through the discharge pipe I 5 and out of the 'hose I6 when the shutoff valve I1 is open. The plunger 25 is operated by the rod M which is secured to the handle 32.. Secured to the rod 3I are the lugs 33..which are adapted to engage within and under'the top portion 2I' of the cup-like member 20 by means ofthe irregular lug receiving holes 2I"to secure the lid 34 to the cover portion 34". The circular cover portion 34 is secured to the upper edge of the body portion II). The handle 32 is further secured to the lid 34. The handle 32 is turned slightly to disengage the lugs 33 from the irregular receiving holes 2| so that the handle 32 together with the lid 34 may bedrawn upwardly, thereby allowing the plunger 25 'to move upwardly within the casing 23. r

' The pressure relief valve I3 is composedof the vertical rod 35 at the top of which is secured the cap 36 which operates to move upwardly and downwardly over the cylinder 31 against the action of the spring 38. As the cap 36 is moved downwardly the washer valve 39 and retainer 40 also move downwardly, allowing air pressure which may have been built up within the body portion II) to escape through the valve. A hole or aperture 4| ispformed in the cover 34 in such 4 V a position that the pressure relief valve I3 will extend therethrough for easy operation. When the lid 34 is closed upon the aperture 43 of the cover 34, the closed compartment 42 is formed wherein the -fil;ler hose Stored. ,v 7 My device is operated in the following manner. When the lid 34 is in a closed locked position thehandle 32 is grasped by the user and turned slightly in one direction or the other to disengage the'lugs 33. As a result the lid may be moved upwardly and downwardly which allows the plunger 25 to build up pressure within the body portion III by moying the handle 32 in an up-and-down movement. As pressure is built up easily and readily within the body-portion- I0, any liquid therein'will tend to be driven upwardly into the-discharge pipe I5 and outwardly through the 'filler hose I6 to the valve I1. The filler hose "IIi'is conveniently coiled in the compartment 42 formed .by the top portion.- I2, the cover 34',- and the lid 34. The filler hose IIi is" uncoiled and placed in a container which is desired to be filled. When the container is filled, the liquid or fuel remaining in the filler hose-I6 may be drawn back :into the-body. portion I0 of my fuel filler can by releasing the pressure therein by means ofthevalve I30 1 My fuel filler can A is filled with liquid by engaging the lugs.33 under the portion 2| and turning counter-clockwise thereby removing the cup-like member '20 together with the pump unitB.

.My device may alsopbe u'sedfo'r siphoning fuel or liquid from a container into'the bod portion .IIl ofmy fuel filler can by forcing fuel into the filler hose I6 inthe manner-above described and inserting the end of the filler hose 115 into 'thefuel .to be siphoned with the valve I! open.

The pressure relief valveI 3 is then depressed and opened, allowing the Jfuel or liquid in'the filler hose I6 to return'to thezwfiller can A, drawing with it the liquid or fuel-in the containerwhich is desired to .be emptied into my:fue1'filler;can.'i

In Figure, '7 I-have illustrated a form-ofa pressure; relief :valve 0. .The valve; C is operated when the lid 34 iszmoved downwardly and locked in'position, the outer portionof the lid contacting therod .45 which is in turn pushed downwardly opening the valve proper:,46. The valveCis secured to. the top portion .12 :with the,-.rod,45 extending through a small hole formed ini the cover portion 34'. Thuswhen sufiicient air'pressure is built up within the filler canA, the lid 34 is closed and locked inpositionthereby opening the valvec allowing; the fuel in the filler hose. to tu n t the fille ca as'a re u t of the pressure on the tollsurface of the fuel'being relieved by meanslof the operation of the valve 0.

In Figure ,8 I haveillustrated a formof a pressure relief valve D whichiis positioned on'the' i 0 the fill pan -a d h s exe tends upward through an aperture 41 formedin the lid portioh 34.- The valvel he ad 48 is p hibited from .niakingia completeliseal by a. small channel Pdr 'n .9 w i h ellewsa s al m unt of airto escapesalthough thevalve head is on its seat. The cvalve head 48 is opened "com; pletely by pushing downward on the-button 50 when it is desired toreliev ethe air pressure on the fuel in thefillercanAl 7 A I In Figure 9 I have'illustratedaform'oftanair pressure release which embodies airaised' portion lease of air pressure at all times, but small enough in diameter to allow pressure to be built up on the fuel in the filler can. The raised portion 5| is formed on the top portion l2.

The air relief valves in the container do not interfere with the securing of sufiicient air pressure to force the gasoline or liquid fuel out of the container when the pump B is operated.

A series of drain holes I2 are provided where the top portion I2 joins the outer wall portion ID to allow any liquid which is collected on the top portion I2 to drain from the compartment 42. This leaves the compartment 42 which contains the hose, dry at all times.

The shutoff valve I! may be equipped with a removable strainer screen (not illustrated in the drawings). However, this screen is of ordinary construction which will prevent any foreign matter entering the gas tank of the outboard motor or the vehicle where my filler can and hose are used.
