To all whom t may concern:

Be it known that I, WILLIAM GRUs, Jr., a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Oil-Cups, of which the following isa specification. v

his invention relates to al device for attachment for admitting oil or inserting oil to a bearing or vinto anyplace in whichv a liquid is used, and although intended principally for use with oil it can of course have a more eneral application. The rincipal object o the invention is to proviso anew and improved form of oil cupl which is sim-y pleand inexpensive to construct and effective and eliicient operation. l

In the accompanying drawing, Figure 1 with a portion broken away of an oil vcup constructed in accordance with the principles of this invention; Fig. 2 isla sectlonal View taken on the'line "22 ofFig. 15 \Fig. 3/is a sectional! view .taken on `the lmel 3 3 4shows the form of a blank from which the of Fig. 2; Fig. 4

cap is made; Fig. 5 is a sectional view of the preferred construction vof an oil cup/embodying this invention, and Fig. 6 is a'sectional view taken on the line 6 6- ofI Fig. 5.

In most of the oil cups lof the class towhich this invention belongs, that are in use at the present time, thereis some deficiency which renders them unt fory continuous service. Frequently the caps are hinged to the body of the oil cup or the cap is slldable relatively to the body uncovering an aper ture through which the spout of the oil can may be inserted. Or there is a slide or movable portion in connectionfwith thel side or top of the oil cap which when' moved un-A covers an aperture for the insertion of an oil can spout. All of these constructions are unsatisfactory for the/reason that if the cap -is hinged the connection is usually of suc a iimsy nature that olthe cap,

the least jp11/ll will `tear and .in the slidable or movable part constructions the least dentor inaccurac will make it impossible to slide the mova le parts, thereby rendering it impossible too of oil. I springs are used they frequently do not seat the cap or cover properly which will ermlt the admission of dirtad grit, there y decreasing the eiii'ciency ofthe oil cup, if not actually clogging it. In the f self closing, it is grasping the crimped edge en the oil cup .for the insertion present construction these diiculties are overcome by having a spring which may be compressed aonsiderable amount, thus allowing the cap to be raised above the body ofthe oil cup to a considerable distance for the insertion of oil. -A spring is provided which `tends to seat'lthe cap evenly and firmly so that there is very little opportunity for dirt to get in'the cup, and being proof against inattention on the part of the operator. f

Referring now more particularly to the drawing, an oiljcup body 8, as shown in Figs. 1, 2 and 3, is formed aty one end with a threaded portion"-9 adjacent;A which is a hexagonal portion l0 for screwing the body into a threaded aperture. The other end of the body isentrely open with the exception vof opposite tongues l1v which are bent inwardly a `short distance with extremities 12 bent into .the body 8. j lA c'over or .cap 13 is formed from a blank, as shown by Fig. comprising a rounded central portion 14 with oppositely extending arms 15. The arms are bent substantially at right angles to the plane of the -cap so that they may be' inserted in the `body 8, as clearly shown in Fig. 3, the edge ofthe central portion 14; being crimped around the edge'l, as shown in Fig. 3, to form a seat which rests against the open edge of the body 8. The extremities 17 of the arms 15 are bent inwardly and then at right angles, as shownv in Figs. 2 and 3, so that when the cap is applied* to the body the bent extremities 17 and 1l are opposite each other.k Between these, extremities a coil spring 18-is inserted which'is held in place by tliebent extremities tending to hold' the ca over and closely against the /open end o the body portion 8. The spring is worked in place vwith the lcap partially raised and whenU/in .position there is no tendency for it to become dislocated nor to bear vunevenly upon the cap. 'Ihe cap is easilyAY raised for theI insertion of oil by 16 at any point', or at opposite points, as the edge of the cap protrudes beyond the body 8.

In the preferred form, as shown by`Figs. 5 and 6, the body portion 19 ofthe oil cup is vshown to be made of a tubular member which is reduced at one end forming the threaded portion 9 and an intermediate `headed portion 10. A cap 13;is made of a blanx similary to\that shown inFig. 4' and the rounded portion of thecap is strengthened by an insert 20 which is crimped and held in place at the edgesfwhen the cap is formed. Instead of bending the extremities of the, arms 15 and forming tongues on the body portion of the cup in order` to hold the spring 18 in place, a pin 21 is attached adjacent the open end. of the body 19 andthe extremities 15 of the cap member are joined by a pin 22. As shown in Fig. 6, this pin 22 is formed with flattened or upset portions 23 adjacent the ends to prevent the arms 15 from moving inwardly, and the ends of the j arms 15 are bent slightly as at 24 so that the heads 25 of the pin 22 will be'flush with the Aouter surface of the arms. This will facilitate the insertion and operation of the cap in the body. y

One of the principal advantages gained bythis construction is that it can be made `of thin tubular and sheet material by punch press operations. This makes the/construction simple, strong and inexpensive, and one that is not likely to get out of order. The cap is easily raised for the insertion of oil and is held strongly but evenly on the body of the oil cup. The coil spring is not easily displaced and leaves a large central opening for the admission of oil, at the same time permitting the egress of air at the time of g. What I claim is:

l. In an oil cup, a receptacle` a non-y tilting ycover for the receptacle having yparallel arms extending into and closely.

adjacent the sides ofthe receptacle, and a spring inserted within the receptacle and between the arms tending vto hold the cover on the receptacle.
