' oIL CUP.

. Application filed September 24, 1921. Serial No'. 503,007.

lOur invention relatesto'oil'cups and for onevof .its objectsv the provision of a simple and eflcientimproved oilcup adapted to keep theoil clean and feed the latter to vent dirt and foreign material from passing a bearing as such -oil is used. .n `A further object ofthe invention 1 s the provision of an improved oil, cup having a wick therein to regulate the flow ofoil from the cup. 4

A further object is the provision of simple andeflicient improved means for vautomatically maintaining the oil cup closed, except when being filled.

\ Other objects of the invention will appear` hereinafter, the novel features and combina-v tions beingset forth in the appended claims.

An embodiment of our invention is illustrated in the accompanying drawings forming a part of this specification and ,in f

Which- Fig. 1 is a plan view of an oil cup including our improvement;

Fig. 2 is a central vertical section of the device shown in Fig. 1; and

Fig. 3 is a small elevational view of the oil cup shown in Fig. 1. y ,f n

Referring more particularly to the vdrawings, we have illustratedv an oil cup having acup proper 21 which may be of any approved shape and size. and be yformed preferably of sheet metal. The bottom portionr 7 of the cup is provided with ,ay discharge passage 9 leading through the threaded portion 8 up into the` oil yreservoir 10.r We pro-f vide a wick 11 in the passage 9 so as to retard theilow of oil from the kcup and` prethrough the cup to the bearings to which the oil cup is adapted to be connected'. Although 'our improved oil cup is particularly adapted to be connected to bearings of a vehicle, it may have ageneral application. `Then connected to a vehicle, the jolting thereof will facilitate the passage of the lubricant from the chamber 10 to the wick.

The bottom 7. of the oil cup may be of metal castingv provided with a shoulder 19 which is engaged by a flange 2O of the sheet y metal cover-21 which is provided with a yielding opening 22fin its central portionin the top and in substantial alinement with the inverted cup 16. A spring 17 is located between an annular shoulder 'or seat on the tubular portion 23 and the lower peripheral I11. of the wick above the tube 23. n spring 17 presses up against the cup 16 so edge/.of the inverted cup' 16. Therspring 17 thecup 16 tight-ly against the under sideof the cover `21- so as to close the filling pening 22 against the entrance foreign materials.H p When it is desired to fill the chamber-,10

with oil, an oil can, not shown, orA otherr in strument, may be. inserted through the opens vis lpreferably of such a strengthas to hold y ing 22 ,and againstthe cup 16. Pressure is f exerted byv means of. the nozzle of the. yoil can suficient to compress the ,spring 17'so that theoil canpass over the top of the cup 16 down into the reservoir 10. yUpon .re-

moving the oill can or other instrument from the filling opening 22, the spring 17 will Yagain compress the cup `16jup against .the cover 21 to close the opening-p22- y,

A centralv tubular upstanding extension 23 from the circular bottom 7 isiincommunication with the. discharge passage 9. The4 wick 1,1v is extended upthrou'gh the tube 23 with a portion of the wick'disposed on' the top of this tube. The invertedk cup 1 6 is therefore slidably mounted on theouter side of the tube 23 and covers the portion The as toautomatically close the opening 22.

Near the bottom of the tube 23 vare a plu- -rality-of openings 24 which permit the oil topass (from the reservoir 10 into t-he tube 23 and down into'th'epassage 9 aswellas up ardly by reason of thecapillary attraction ofthe wick 11. lWhen the cup 16 is moved downwardly to ll the chamber 10,with` oil, the cuplt presses the` portion 11 of the wick, thereby tending to squeeze the oil down intoV the passage 9 and thence to the bearing to which 'the'oil' cup is connected. Then the oilcan or other instrument is removed fromthe the structure shown in the drawings Norinally the spring 17 presses the bottom of this inverted cup against the opening 22 so as to close the same7 thereby keeping dust sageway 9 andto suck the oil up along to# .Ward the upper en'dof the Wick when the pressure"onth'einverted cuplis released. Fur-` i "thernioreftliewiclr acts asa iilter'to kprevent any grit orforeign material in the oil froml reaching the bearing to be lubricated.
