(01220-55) The. present invention relates :to Vauiill cap and Will-be herein described as a yquick aopening. ll cap for truck tanks.

Truck tanks., such for example asare :utilized 5 for the transportation and-delivery of gasoline, fuel -oil and the like, in order .to .be economically operated, .must be provided with .means Ifor quickly Vreplenishing .the yempty tanks, :so that the inactive vtirnemelen'ient of vsuch trucks may be reduced to a minimum. This is especially. trueof `the lighter .truck .tanks used 'for :de- -liveringfgasolina 'fuel oil and the like to retail trade, small lling stations, home garages and. domestic fueloil tanks, .Where .such vtrucks are filled several times a day.

` .The -tank must `be :provided .with ill `caps which prevent eva-poration and gas leakage, .whichvmust be quickly .opened tandrclosed, andrwhichmust be so rconstructedfas not fto .accidentally open because. of vibrationcincidental to the operation of the trucks along thestreets and roads;

The :present invention is Vdirected to, and 'has fornaniobjecm .affll cap Whichpzmay-be ,quickly and easily opened and closed by simple inloveinent of za handle, andwhichis `locked-in `closed position so asnot to accidentally open.

A further object vv of-,the invention `is to provide ,an'll cap c.onstruction.includinga lneck and a lid, :wherein ithe .lid is :provided lwith :means for locking;` engagement V nwith the neck and also with .a handle for actuatingrsuch locking smeans. Y ,.'A=zstill..gfurtherv object :of the invention ,.isito provide a-f1ll ,cap .construction includingl a :neck and a lid,'withfcam actuated, locking means carried loyqtheglid,` together with zan vvactuator, andzthetprovision of 'means `for :retaining the lactuator.against movement in sunlocking direc- .tion .after it has Jbeenrmoved to effect lockingy engagementfofvznthe lid withtheneck. 1

The under surface of the lid 2 is provided with an annular channel 14 in which is inserted a gasket 15 for resting against the upper margin of the neck 1 when the lid is thereagainst applied, for sealing the joint between the lid and the neck.

The neck 1 is shown as provided with outstanding. lugs. 16.and 17, shown as Adisposed on oppositelsides ofthe neck from the center of the same, which lugs may be integrally formed with the neck or may be separately formed and'g` u bery 24 by the spring within the pocket. The underside of the hooded member 24 is provided with a recess 32 i-nto Awhich the ball 30 snaps, ',.When' vthe hooded member is moved to the extent permanently connectedv to the neck as desired.

The lugs 16 and 17 are herein illustrated at substantially diametrically oppositepoints. The lid 2 carriesvupstanding pivotsr lstuds 18 and 19 which may be formed as part of the lid when cast, or if otherwise made,l may be in serted. Inasmuch as these studs are desirably of different material or" which the lid; isfmade they preferably are inserted in the lid.'

Locking members, hereinreferred to a's pawls, are pivotally disposed on the pivots 18. and `19. The Vpawls are similar in constructionand therefore .will be designated. byv the same reference character. The pawlsv 20 are provided with downturned ends 21 havingv a/lip or foot 22 projecting laterally and with the upper surface preferably inclined. yThe inclined surfaces of the lip` 22 engage the under surfaces of the lugs 16vand 1,7 fordrawing the lid 2 tightly against the neck 1 as will be hereinafter described. The inner ends of the pawls 20 are provided with upstanding projections or pins 23. The downturned extremities 21 of the pawls 20 lie adjacent the exterior of the neck l so that as the pawls are actuated, the lips 22 will be moved into or outof engagement with `the lugs 16 and 17.

For rocking the pawls'20 about the pivots18 and 19, an actuator, consisting inv the .presentin' stance of a hood 24 having a handle25l as a part thereof, is provided with a centrall aperture 26 to surround the upstanding vboss 11 of ythe lid 2. The underside of the hoodedmember. 24 is provided with camslots 26 and 27 (see .Figure 4) for receiving the pins 23 of the pawls 20. The hoodedr member 24 is applied over theboss 11 of .the lid 2 withth'e cam slots26 and 27 on `its underside so that the slot v26 receives the piny23 on the lower pawl of Figure and the slot`27 receives the pin 23 of the upper pawl of` Figure 5. The hooded member or actuator issecured to the boss 11 in any suitablemanner, .a spring ring 28, engaging a groove 29 in the boss.11',zis herein securing. the actu-v illustrated as the means for ator in place on the.lid-2. A, y

The full line position of the handle 25,0f Figurev 2 is the, position voccupied bythe' actuator when the pawls arein locking or closed Vengagement with `the lugs 116l and 17 andthe dotted line position of the handle of thisrgure shows the open or unclosed or unlocked position.. It will be` observed that as the handle 25 is moved from the dotted line position ofFigure 2 to the full line position of the gure, .the'engagement of the Ycam slots 26 and `27A of the pins 23 of the pawls 20wil1 oscillate these 4pawls about the pivots 18 and19 to increasethe distance between the pins 23 of the pawls and-thus move the .lips 22 thereof underneath the-lugs 16. and 17. vBecause ofthe inclined surfaceengagement between the lugs 16 and 17 andthe lips 22 ofi the pawls 20V the lid 2 isforced tightly against -the neck inthe direction `of `theaxis of the neck to thus eciently seal thef.joi`nt.between the neck and the lid. Movement of the handle in the opposite direction will draw the pins 23 together or towards each other thus releasing the engagement of the lips 221with the lugs 16 and 17 to unlock the lid whereupon it may be swung back from the neck about the hinge pin 6.

In order to lock the lid in closed position any suitable means may be provided. There is herein illustrated akspringl pressed ball 30 carried in a pocket 31 formed on the top side of the lid and urged against the underside of the hooded memlof movement in' locking direction, whereby the hooded member is then locked against accidental movement. The tension of the spring, actuating the ball 30-is such as to enable manual manipulation of the hooded memberbut is suiiicient to prevent .any vibration from dislodging the hooded member when locked in the manner'described. H The 4provision ofthe elongated recesses 5 in the ears 3 and 4, l.'forthe hinge pin 6, permit slight.relative'movement. of the lid 2 with respect to the neckljinjother than arcuate travel so that the lidmay be tightly clamped against the neck 1 without imposing undue strain on the hinge pin or any of the hinge parts.

`.It willbe observed that thef iill cap ofthe present invention is constructed to eiecttight sealing between the lid and theneck and that theprovision of the manuallyfoperablehooded member 24 causesquick action ofthe pawls 20 into and out ofv locking engagement with the lugs 16 and 17.

.The construction. of the parts is such that all .are..freely operable when sufficient hand pressureis applied` to the'handle 25 for unlocking or locking thestructure. f.

The neck 1 is shown as provided with a ange 33 which may be Welded to a tank in any suitable manner.

The provision ofthe gasket 15v makes a vapor and dust tightjoint between the lid and neck.

The vparts are so designed and constructed as to enablel production of the fill cap of the pres- .ent Ainvention at low manufacturing costs.'

Any suitable air vent may be applied tothe bore 12 as occasion may require. y

' The invention `haszloeen described herein more Yor lessl precisely as .to details, yet it is to be understood that the inventionisnot to be limit-v ed thereby, as changes maybe made in thearrangement'v and proportion'of parts and equivalents may be substituted, without departing from thespiritandy scope of the invention. -The invention is claimed asfollows: .s 1.
