application filed Agust 19, 192g. ,seggi ne m4rt1n f y To all whom t may concern.'k i i vBef it known that l, JEAN F. VoLrsa citizen of the United States, and a resident of Newark, county of Essex, vand 'State of New Jersey, have invented ycertain neWfland usetul Improvements in Oil Cups, of Which the following is a speciiication.

rIhis invention relates to an improved oil cup Which is Aparticularly adapted for, use on elements that are jostled or vibratedasuch as thel shackles of steering `gears or on the eye bolts of leaf springs onY automobiles, and

Which cup ydoes not feed oil When the parts are atrest, but begins to feed as soon as the parts are 1n use and agitated.

The oiler isde'signed so vthat the inner' end ofthe outlet tube of the oiler is above thele'vel of theoil and the inner Walls are disposed so that Whenthe oil in 'the cup 'is splashed its general ymovement is in the direction of the inner end of the outl'ettube.

The invention is also designed to provide an oiler in which the lilling is limited, due

o to the 'construction,l so ,that "an air chamber outlet tube, is supplied with oil. .n The` Wick is also advantageous lin lthat small quantities of dirt, which, if they aecumulate, form ta stoppage,de not lodge in the Wick.

'The invention is illustrated in the accom-r panying drawing, in Whichy Figure l is a section with the lower part in elevation, showing" one form of oiler embodying my invention. l `igure 2 is a section` lookingl .il'jward, taken on line 2 in Figure l. Fig;-` ure 3 is a sect-ion of a-modied form,` and Figures at, 5 and Gare sections ofthe Vupper 'portion of several oilers of a still further modified construction. The oil cup comprises a main portion'or container l() which, in Figures l and 2, comprisesa dome-shaped member ll and a hat end piece l2, which are usually secured together by any usual means, preferably brazing, andas this orm is designed to provide, for a 'horizontal facing@` of eine iena y piecelQ fis*providedA with a hub 13 which is usually*screw-threaded" that it can .be

The material itselfofwhich the Wick iskcomposed is notr absorbent, but being-gathered y'looselyin a Wick sheds 'the'major portion of oil that is deposited Y-on'k it, 'but`r the lm of oiljthat is establishedl around the'fwires, and the small drops lthat lodge in betweenthe strands, are y conductedby capillary 'attraction along ythe toy Abe lubricated 4 Themember llwith its curved or semiarched top `directs oil that is splashed up Ward -tovvardthe yWick and oil is thus threwn Wiek andthronghfthe outlet tube kto the'ipart up and over the wick when the container is shaken or agitated,kas itwould be, ror iii` stance, on an automobile when the vautoniebile is in motion.

In Figure 3 is shown another `form in which the containerr is adapted to be placed on top of the element to be lubricated; in other words, the feed is downward. The cas r ing 23 is substantially spherical `and is prrr vided with a suitable 'head Ql-"by means of which it is secured in place,vthe converging `inner walls .cooperating with the vfilling tube 25 to form the airy chamber 2,6. r)lie `filling tube is j closed by a, suitable plugQT and the inner end 28 of the outlet tube 29 is preterably turned over so that its open end faces downward and` oilis not directlyl depositedL into fthe outlet tube. The outlet end `30 of theoutlet tube projects out tothehub 23 and being a line tube, is usually strengthened by securely fastening it to the outer end ofthe hub, it' desired, this being inthe :torni of a. deposit of solder 3 1.

` The wiclrQl i'sarranged inthe outlet tub/ve f outside of it` at the bottom, the Aoutlet tube 34 being connected atene-point with the gutter 33, vand the` loop 22 ofthe wick 2l lyingl in esaid gutter to transmit from said gutter to the outside of the oiler oil ,depositedin the'gntter when the container` is agitated. i y

' In Figure 5 I show a vconstruction,somewhat similar to Figure .4, vin which Athe lilling tube 35 entersthe gutterA from the top` instead of thebottoin, kand inFigure 6 I show a still `further modification in which the outlet tube`36 is shown, thistube ken.n tering the side of the gutter andextending down in ysaid gutter nearly to 'thel bottom thereof 'so' as to syphon from lsaidgutter, oil that is lodged therein, as willkbe readily understood. g, .These different forms are used according to various circumstances, such` asthe weight of the oil and` also bearing requirements, and therefore I ise .various sizes oftubes,

andvarious sizes and qualities; of wicks, and

also regulate the relative size yof' the tube and the wick, and in addition to` this the length of the wick exposed in the container.

can be varied., y t

As above described, wheny oilvis deposited on the wiclr,eXcess oil drops otl readily, but a small quantity is vconstantly present and Vis carried along by `capillary attraction until it emerges fronithe oil cup at the outlet end of the outlet tube. This wick does not completely block or obstruct the outlet tube asa fibrous wick would, and therefore during quiescent periods allows theY ingress oil air tothe oil container through the outlet tube, sov that there yis no possibility oir an oil. A V 'Illlien -the container is agitated and oil is .deposited on .the wicln suticiently oil is drawii. into the tube by wick` capillarity, and by capillary action between the wiclrand the tube wall to establish syphonic action. @n long `continuedaction, however, ,it the supply o oil,` from the container is steady, there is a reduction or' pressure established in the oil container, which temporarily prevents further `feed until no more oil is supplied, that is, the container has come to rest, or until capillary feed from the tube to the bearing to be .lubricated breaks the syphon, the turned over or syphon end, inthev illustration this being the inlet end or the outlet tube, preventing any direct splashing into theoutlet tube, and also cooperates with the wiclr'to act as an oil filter to prevent foreign material passing down through the outlet tube and entering the bearing that is tol be lubricated. In view of the non-supply of oil when the container is atrest there is a great economy of lubricant,vsi'nce the feeding only takes place while the vehicle or other conveyance or machine elenient is inmotion. This economy also lhas an vadvantage in that it necessitates only infrequent re-lilling oi the oil container.

ltl .will beunderstood that minor changes can be made in the details of construction ywithout departing from the scope of the invention. f

I prefer to use the loosely wound wire wickl that` is.4 described hrein, but it will beunderstood that under some conditions ot'use a tightly wound wick or awick only partially filling the tube, or Aa woven wick, niight be advantageously employed.

I claim: i i lf. An oil cupconiprising a container, a restricted outlet tube with its inner end air check causing fa cessation oi the flow of ioo above the normal level of the oil in said container, the upper inner faces ot the walls ot lthe container being disposed so that when theconta'iner is vibratedoil is splashed toward saidinner end of the tube, andra wiel; or' loosely wound wire strands in said tube.

2. Anoil cup coinprisinga container, an outlet tube leading from the upper part of the inside `oi: the ycontainer tothe outside thereof, and a wick of loosely wound wire strands in said tube and the inner end thereof.

3. An oil cup comprising a container having a illing tube extending from the top partway into the container so ythat an air chamber is formed when the oil level reaches the bottom the filling tube, a closure for projecting from iso ing its open end in said air chamber.

il. in oil cup Comprising :i Container having a. filling tube extending from the topl part Way into the container so that an air Chambei is toiined around said tube when the oil level reaches the bottoni ot the tube, e closure for Said iilling tube, an outlet tube extending to the outside of the oontainei and having its open end in said :tir chamber, and a Wick of loosely gathered Wire strands in said tube and extending belvond the innei` end thereof.

5. An oil cup comprising e container with L filling tube extending inwaidly ici-0in its top Wall to foiln en iii-,chamber when oil reaches the bottoni ot the filling tube, en outlet tube extending from the outside of the Peeing to the air Chamber, said inner end being curved to open downwardly, and e.. Wick of loosely arranged Wiie strands filling said tube and extending from the inner end thereoI to forni e loop.

lrn testimony that claim the foregoing, l have hereto set my bend, this 18th day o August, 1920.
