1 UNITED I Specification;

To all whom may Be it known that L. Samara-e Ewen;

residing at Newton, 11'1" the, county of lVI -iddle sex and State er Massachuse have in} 'vented an Improvement in Oil-Cups, of

which the following is a specification This inventlon. has reference to oil-cups,

and particularly to the closing means there for. The invention has for itsobject to construct an IIDPIOVQCl self-"clos ngdevice for an oil-cup comprising 'a disk having an annormally closed position, and also having an ear at the apex of the boss, and a, spring connected atone end to said ear which extends lengthwise through the cup and is connected at its opposite end to a cross-bar which is arranged in an annular recess at the bottom of the cup and which admits of a rotary movement of the disk and spring relative to the cup, so that in case the disk should be turned accidently or otherwise, the spring Will not be unduly strained, and the end connection of the spring with the ear is sufliciently remote from the-boss to provide a space therebetween. so that said ear may engage the edge of the top of the body and rock thereon when the disk is tippedto open and close the cuprand toad-- mit of said disk being tipped up into approximately a vertical position to open wide the top of-the cup.

The invention also has for its object, to connect a non-extensible link with the spring by which extension of said link is limited, said link, however, being connected with the spring so as to admit of rotation with the spring and disk whenever the disk is turned- With respect to the cup.

F igure'l is a side elevation of an oil cup embodying this invention. Fig. 2 is a vertical section of the same. Fig. 3 is a view similar to Fig. 1, the closing-disk being tipped up into vertical position to open the cup at the top. Fig. 4. is an under side view.

or represents the cylindrical tubular body I of the cup having a threaded end portion and a hexagonal intermediate portion.

Z) represents a closing-disk for the top of the cup, which, as here shown has a conical boss b on its under side to enter the opening s'rnnnine .nnnrorr or vnw'r olv of Lettersf'Pa'tent.

e1, 1910'. ser al reassess MAssacHns rsi v at the top of the cup andjan cart? at the apex of said boss, and an annular seat 6 surrounding said boss to engage the top of ,thec p; I p i 0 rep're'sei'its a coiled-spring which has coils at its upper end to connect it with the ear bflfa'nd said spring is made long enough to 'extentl'"tlirotigli"the cup and has coils at its lower end to connect it 'to a cross-bar c'fsaid' cross-bar extends diametrically across the bottom at thecup and isarran'ged in an annular recess formed in the cup at the bottom. Said cross-bar is treeto be turned in said recess, so that in case the disk Z) is turned accidentally or otherwise, the spring will not be unduly strained and its efficiency thereby impaired as would be the case if the lower end of the spring was connected by fixed means to the bottom of the cup. than the opening through the body adapting it to be moved into an inclined position to permit the disk to be tipped up into vertical position, as shown in F 3, to open the cup at the top, andsaid spring acts to im mediately return the disk to normal position as soon as said disk is released. The disk when resuming its normal position is centered by the conical boss so that it becomes properly seated on top of the cup. The upper end connection of the spring with the ear is suflicien'tly remote from the boss to provide a space therebetween so that said car may engage the edge of the top of the cup and act as a fulcrnnrlever when the disk is tipped upwardly to open the top of the cup and to admit of said disk being tipped up into vertical position to open wide the top of the cup. It will be noted that the distance between the end connection of the spring with the ear and the boss is approximate]; as great as the thickness of the wall of the tubular body and the ear is thus adapted to rock on the edge of the top of the cup. The cross-bar is detachably connected with the spring by reason of extending through the coils at the lower end thereof, but held in the annular recess by the spring. To prevent the disk from being lifted or tipped up so far as to unduly strain and thereby impair the efficiency ot the spring, a non-extensible link (Z, cont posed, as here shown, of wire, is provided, which is arranged at the side of the spring, and said link is made longer than the spring, and its ends (Z and (Z are bent over to form Said spring is smaller in diameter hooks which extend into the openings in the opposite ends of the spring, as for instance, said ends d and d may extend through the coils, as represented in Fig. 2. Said link, however, is quite independent of the spring and permits said spring to be extended, but acts to limit its extension. In case the disk is turned and the spring is turned with it, the link which is connected at its ends with the spring also will be turned.

I claim The oil-cup herein described consisting of a tubular body, a self-closing disk at the top thereof having on its under side an annular seat to engage the top of said body, and a conical boss arranged within said seat having an ear at its apex, a spring extended through said body which is connected at one end to said ear, and means to rotatably connect the other end of said spring with the bod the end connection of said spring with the ear being sufficiently remote from the-boss to provide a space therebetween to admit of the ear engaging the edge of the top of the cup and rocking thereon as the disk is tipped to open and close the cup, and to admit oi said disk being tipped into a vertical position to open wide the top of the cup, and a link contained in said tnbular body which is made longer than the spring having hooks at its ends to provide 'for sliding engagement with the spring whereby extension of the spring is limited.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
