OIL-our.

To all/whom temi/concern: v

Be it l'rnown that. l, DANIEL Timms, a citizen ofl the UnitedStates, resid-ingV at Chicago, in the,l county' of Cook andState oflllinois, haveinvented ay certain". newand useful Improvement; in OilvfCups, of which the following is; av full, clear', andiexact de-k I scriptioinreferencebeing, had to the accompanying drawings;

This invention relates toi oilVV cups of a type having a tubular bodyon cup `portion opening upwardly and having a` coveradaptedatobeiopened for` filling the cup, said cover beingA closed and held in.y its: closedf position by the action ofthe spring within the oil cup; t

The object of the invention isto provide a simple, efficient and durable spring which may bev Very cheaply manufactured, and which may be;` replaced in'- case it*` should be brokentxbyv the use: of extraordinary' force.`

My invention is hereinafter; more fully described in connection with the drawingsand theessentialf characteristics set forth lin the claims.

In the; drawings, Figure 1 is a sideeleva` tion of the oil cup; Fig.vr 2 is a central'y vertical section showing the spring for closing the cap.;` Fig. 3 isa central vertical section showingy a: modified construction of they spring;` Fig. l is avertical section taken at right anglesto the plane of Fig. 8, showing anfV elevation of the same spring; Fig.. 5 shows; a-.Inodified construction Iin which the spring and cap are integral; Fig. is af vertical central section through a cup formed ini thefshape ofl an elbow showing the form ofa springshown in Fig: 1i, adapted'ffor this cup; Fig. 7 ,is a vertical section through an,

elbow. cupi showing `thespring vsimilar to that in Fig;V 2r mounted therein. f,

In the drawings, 10 indicates the body portion `oncup'having ai `threaded portion 1l at, itsilowen endend, an intermediate angular portion lQzby" which it' mayrbe screwed into position: At ltheaupper end, the cupiopens upwardly and is normally closed by 'a cover 14' having a downwardly turned flange 15 extending partly1 around theu cover. Theeffectzof-theilange is toposition the capwhen drawn tn' closedpositioni and add toithe apy Specification of Letters Patent. A Patented @3c-ft.

pearance of the cup. The spring for holding the cap-or cover in position is a fiat leaf spring lShaving a portion 20 at its upper end lying contiguous. withfthe under side ofthe cover andadapted tobe securedthere to' inA any suitable manner; As shown, a rivet 2l` is passed through the spring and cover, but any suitable means may be usedfor securingfthe spring to the' cover, as, for enamplegthisi portion ofthe spring` may be electrically welded/to the cover, or have an upwardly turned flange passingy through the cover and upset at its upper end. The spring has a narrowed intermediateportioii andl is made yintegral with two outwardly extending wings 23' at its lower end,` which liein a'y slightly enlarged bore 2li on the inf terior of the oil cup. When the spring is in Y on: the edgeofthe cover providesfor pushingvk the cover to the open position by the spoutfof an oil can', if desired. Als soon as the cover isrelea'sed, they action of the spring isto drawk it back, sliding it across the top of the cup, to its closed position.` il suitable notch is inadeinthe upper edge of the cover to clearthe spring and the meansfor securing it to the cover.` asindicated at 28;

A modified construction ofthelower'end of the spring is shown ,in Figs. 3 and. il, in

which, instead'y of the curved wings Q3, straight wings 30 are provided, which engage slots.Y 31 at each `side ofthe cup. At the upper edge of each of these wings is formed a squared shoulder 32, one portion of which engages'the upperend of the notch and' the-other portion the inner surface of thecup, tending to` center the wings of the spring-land preventing. the saine engaging the threads and thereby injuring them while being Vscrewed intoposition.

In Fig. 5 is shown a modified construction of the spring, which may be used with either of the forms just described, and consists in lmaking the spring and cover of one strip of metal formed into substantially the shape shown, and having a portion integral with the edge of the cover opposite the flange l5, and extending inwardly along the under surface of the cover and then downwardly, forming the main portion of the spring, as in the other forms.

In Fig. 6, the spring 18 is'given a curve at its upper edge, similar to the curve in the first forms described, and then, an opposite curve 38 at its lower end, bringing this end of the spring into vposition to lie substantially parallel with the axis of the threaded portion, as indicated at 89. In this form the spring is provided with wings similar' to the wings 30 adapted to be tightly driven into slots 3l formed the same as the slots shown in Figs. 3 and el. This allows the spring to press the cap into closed position, that is, the spring acts toward the right in this figure. f

In Fig. 7, the body portion of the spring is given a curve similar to the curve 38 in Fig. 6, but the spring is secured to the cup by means ofwings 40 similar .to the wings 23 which engage an enlarged portion 4t2 of the bore on theinterior of the cup, and rest against a shoulder 43, which prevents the wings sliding toward the upper end of the cup while the wings 4t() themselves tightly engage the inner surface of the bore 42 by spring action, thereby securely holding the same in place. To more securely holdthem, a suitable rivet as shown at 44, may be passed through one or both of the wings.

In each of the forms described, the spring is so bent that it pulls downwardly on the cap or cover, holding the same tightly in place, and it is so constructed that it may be bent, allowing the cover to be slid across the top of the cup a distance great enough to provide an opening for filling, ywhile not allowing the cover to become displaced. In each construction, the spring acts to return the cover to closed position as soon as it is released.

vHaving thus described my invention, what I claim is:

1. In an oil cup, the combination of a cup portion, a cap, a leaf spring secured to the cap at one end and to the cup at the other end tending to draw downwardly on the cap while allowing it to be slid open for relling.

2. In an oil cup, the combination of a cup portion, a cap for closing Vthe upper .K end thereof, a. leaf spring secured to the ycap at one end and extending downwardly in side of the cup and having an engagement with the interior thereof and tending to draw the cap downwardly while allowing it to be slid across'the cupv against the tension of the spring.

3. In an oil cup, ythe Vcombination of aw member rigidly secured to the cap Vnear lone edge thereoffand extending ldownwardly within the cup and having wings at its lower end engaging the lower 'end of the cup, said spring member tending to draw downwardly on the cap and exerting a lateral tension on the same.

5. In an oil cup, the combination of a cup portion, a cap for closing the upper end thereof, a fiat spring secured to the cap 'near one edge thereof and curving inwardly and downwardly within the cup and having outwardly extending wings at its lower end engaging the interior of the cup, said interior being provided with a shoulder against which said wings engagepreventing their upward movement, whereby the spring may act tov draw downwardly and laterally on the cap.

6. In an oil cup, the combination of a cup portion having an open upper end, a cap adapted to close the same and having a downwardly turned ange extending partly around the same, and a spring attached to the cap near the side opposite the flange and curving inwardly and downwardly and having outwardly extending wings at its lower end engaging the interior of the cup.

7. The combination of a cap for an oil cup and a spring member integral with the cap at one edge thereof and extending inwardly and curving downwardly and adapted to extend into the cup and having means at its lower end for securing it to the cup. f-

8. In an oil cup, the combination of a cup portion, a laterally movable cap therefor, a spring' securedto the cap at one end and extending downwardly within the cup and having its other end engaging the cup and tending to ldraw downwardly on the cap while allowing it to bemoved laterally for refilling.

9. The combination of an oil cup having an yopening in the upper end, an external capy for said opening adapted to be slid across the same, and a Vspring member s ecured `to the closure and engaging thecup` cap against the action of the snrng when it `10 c `und adapted to allow the closure to be slid vto uncover the opening.

l0. In an olcup, the combination of a cup port1on having an open upper end, an

' external cap resting on and closing the upper encl and sliclable across the same, spring means tending to slide the cap toward its closed position,`and means for stopping the reaches its normal closed position.

In testimony whereof, I hereunto affix my signature in the presence of twowitnesses.`
