FREDERICK A. BEnGMANN', ou Mannion, NEWYORK oar. vour.

' Application led February 10, 1923. Serial No'. 618,186.

To all 'whomy t may concern 1 Be it known that I', FREDERICK A. BERG MAN, a citizen of the United States, re-

siding at Merrick, county 'of Nassau and State of New York, have invented 'certain vnew and useful Improvements in Oil Cups,

adjusted positions in such a4 manner as to f prevent displacement of the setting ofthe needle valve by vibration or by any accidental blows.

Another object is to so construct the means for adjusting the valve that any desired number of adjustments 'can be had and which adjustments can be arranged toproduce an accurate predetermined rate o f feed.

A further object is to provide a new and improved constructionof anv automatic closure for the lling hole of the oil cup.

For the accomplishment of these and such further objects as will hereinafter beapparent to those skilled in the art to which this appertains, the invention consists in the construction, combination andv 'arrangement of parts herein specifically described and illustrated in the accompanying drawings, wherein is showna preferredk embodiment of the invention, but it is to be understood that changes, variations and vmodifications may be resorted to which fall 'within the scope of the claims hereunto appended.4

l In the drawings forming a portion of this specification: f i

Fig. 1 is a side elevation of an oil cup embodying my invention. t

Fig. 2 is a central section on the line 2-2 vof Fig. 3.

Fig. 3 is a top view, showing thefilling position to close the filling hole and x Y Fig. 4 is a view similar to Fig. 3', showing the'illing hole closure in open position..

As shown in the drawings, the numeral 10 indicates the usual threaded stem or nipple of the oil cup which is preferably integral with the cylindrical body portion 11 and is provided with a feed conduit 12, termi` position shown in Fig. 3.

portion 11 is slightly flared' outwardly to l provide a bead 15 about which the cover 16 isl spun or crimped in` such a manner as'to be Xed with respect to the body portion 11.

The cover 16 is provided with a filling hole 17 anda filling hole closure 18 is pivotally mounted.` upon the needle valve g stem 19 and is provided`withk a downwardly depending flange 20 which rests'upon thecov- .er: 16 andV serves to space the ,closure 18 from the cover.v f l Pivotally mounted between a pair. of small lugs 21 projecting downwardly from the under face of closure 18, is a 'lever 22 having one of its ends formed Vinto va semispherical plug 23 constructed and arranged to seat within the filling hole 17 and' seal the same when the closure is rotated upon itspivot to bring the plug 23 and hole 17 into" alignment. A small leaf spring '.24 isinserted between the lever, 22 and closure'18 to normally urge the plug. 23 downwardly and a pin 25 is secured in the other end of lever 22 and projects upwardly throughy a suitable aperture in the closure 18 to,l provide a means'for actuating the lever y22to causevthe'plug 23 tov be withdrawn from fthe Y.

away as indicated at j f filling hole 17 when .it is desired to `open or 1 ings: through which free access may bev had i tofthe filling hole 17 when the closure 18 is given a slight rotation `r`in either direction from the position shown in Fig. 3. A -pair l' of

springs

29, 30 have their contiguous 'ends anchored as `at'Bl to the'closure 18 y and their .otherfend's'suitably anchored as at 32 to the fixed cover 16.1so as'to'normally urgeror hold vthe closure`18 in vitsy centralfor closed'v `..The upper face of the' closure 18 is? provided with a plurality of spaced upwardly yprojecting pins 33,the heights of which are progressively increased preferably in'. a clockwise direction starting from the lower right hand pinshown in Fig.`f3- and -a sleeve 34,' pivotally ymounted 'upon valve stem 19is providedwith a radially extend'- `ing arm 35 `which projects' outwardly over the pins 33 and is provided with a recess 36 adapted to neatly engage over any one of the pins to lock the arm against rotation. The upper end of the sleeve 34 is recessed as` at 37 to receive a small washer 88 fixed to llO the valve stem 19, which serves to retain the sleeve 34 upon the valve stem. washer 39 is secured upon the valve stem -1'9 within the cylindrical body 11 and acts as an abutment for one end of a spring 40, encircling the valve stem and having its other end in contact with the under face of cover 16, thus serving to normally urge the valve toward its seat and also to hold the recess 36 of the arm 35 in engagement with a pin 33 when the valve has been adjusted to any of its open positions.

`If desired, a slot may be 'cut into the side wall of the body portion 11 to receive a piece of transparent material 41 Vso as to provide -an inspection window and I prefer to use for this purpose one of 'the synthetic Compositions of m'atte'r such as are used for electrical insulation's but which `are now 'constructed iin such a manner as to be transparent, impervious to oil, and are not i as frangible as glass. The manner of securing this transparent material may obviously be varied 'as desired as long as oil tight joints are secured. Likewise the form of the springs and their points of support vmay be varied and also the number and'heights of the pins 33.

The operation of the device is as follows, if it is desired to fill the cup with oil the pin 25 is depressed to withdraw the plug 23 from. the filling hole 17 and the closure 18 is rotated in either direction against the action of the

springs

29, 30, to bring the one of the

re-entrant portions

26 or 27 intoalignment with the filling hole. The spout of an oil can is then inserted into the filling hole and after the cup is filled the oil 'can is Withdrawn and the closure then springs back under the influenceof the springs tothe closed position'shown in Fig.` 3, the plug 23 engaging hole 17 and acting as a lstop to check the return movement of the closure and to hold it securelyin the position shown'in Fig. 3.

To set the needle valve to the desired feeding position, the knurled sleeve is raisedl against the action of spring 40 and rotated to cause the recess 36 of arm 35 to engage one ofthe pins 33, thus causing the valve lltto be raised off its seat `13 to a distance equal to 'theheight of the respective pin. ItI ywill be noted that if itis desired to close the needle Vvvalve that it is not necessaryto rotate the sleeve '34 and arm 35 back to a certain fixed or starting position as is common with devices of this character, but that the needle valve wil-lbe closed for any position of the arm 35'between any of the pins 33. If desired,`the top face of the closure may have As the pins 33 are secured upon the clo- .sure 18, the settingof the needle valve need not be disturbed whenever the closure is r0 tated for filling the cup. Vhile I have shown 'the need-le valve adjusting means as mounted 'upon a rotatable closure, it will be obvious th'atthe pins 33 could be directly mountedupon the upper outer surface of`- 'any oil cup and that any other form of a filling hole yor closure could be used. l The pin 33 nearest to the projecting pin 25 in l the `'couiit'er 5 clockwise direction Figs.` 3 and 4 is preferably of sufficient height to open the needle'valvezto apoint where a substantially free flowof oil from the cupris i allowed.

Having thus described my invention, what I claim as new and desire to secure by Let-I ters Patent of the United States, is:

1. An loil cup having affixed .cover pro- 1 vided with a filling h'ole,la closure rotatably mounted on said cover, said yclosure having a plug pivotally mounted thereon adapted to engage within said filling hole, spr-ing` means to normally urge said plug towards said filling hole, and means to normally hold said closure ina position yto cause said plug to engagesaid filling hole, said closure hav# ing va reentrant 'profile adapted to expose said filling hole when said cover is rotated against the action of said last named means.

2.` An oil cup having a fixed flat .cover provided with an unobstructed filling hole,"

a level closure rotatably mounted on said cover and having a depending flange to provide a space between said closure and said cover, an arm pivotally mounted upon said closure within said space, said arm terminat ing in a plug adapted to engage within and Y seal said filling hole, resilient means contacting with said arm and cover'to normally v urge said plug towards said filling hole, a

pin on said arm projecting through said clo'l sure, and a pair-of vdivergent. springs normally holding said closure in a position in which the `plug is engaged with said hole, said closure having `acontour exposing said filling hole when said cover is rotated' against the action of said springs.

In testimony whereof I have afiixedv my signature. l
