` lSpecification of Letters Patent.k Patgted Qt, 19 1921i` Application i1ed December 8', k1917. Serial No. 206,174.

To all w hom t may concern.' y

Be it known that I, CARL GUs'rAvn GRON- QUIs'r, a subject of the King of Sweden,

(who have declared my intention of becom-v and is more especially, though not exclu. slvely, concerned with means to clear away accumulation of dust, dirt and other foreign matter preparatory to the introduction of the oil, so that no foreign matter shall be carried into the oil passage.

My invention will be best understood by reference to the following description,when taken in connection with the accompanying drawings of two illustrative embodiments thereof, while its scope will be more particularly pointed out in the appended claims.

In the drawings: v

Figure l is a plan ofan oiling device embodying my invention, showing the same as it appears when closed; y'

Fig. 2 is a plan of the same showing the device as it appears when open for the introduction of oil;

Fig. 3 is a sectional view on line 3-3 of Fig. 2; p

Fig. 4 is a sectional view on line of Fig. 3;

Fig. 5 is a plan of another form of oiling device embodyingmy invention, showing the same as it appears when closed;

Fig. 6 is a plan of the same as it appears when open; and f l Fig. 7 is a sectional view on line 7--7 of Fig. 6.

Referring to the drawings, and to the embodiment of 'my invention which is llustrated in Figs. 1 to 4, inclusive, I have there shown an oiling device comprising two relatively movable parts 8 and` 9, having normally non-registering openings 10 and 11, which may be brought into registration to permit the introduction of oil therethrough into a passage 12, which may be, and in the present example is, a chamber or reservoir for supplying oil through a passage 13 to a bearing surface 14. It should be understood, however, that my invention is by no means limited to an oiling device of any particular class or to the lubrication of bearings of any particular kind, but thatfit is susceptible of very general application.

The part 8 may be mounted'tomove in any suitablemanner on the part 9, but inf the present example is mounted to turn thereon, and is arrangedy coaxially with re' latlon thereto. The outer opening 10 isv elongated in the direction of travel, as best shown in Figs. 2 and 4, and is formed sub-l stantially concentric withthe common axis of the parts 8 and 9. Imay provide any suitable means movable lengthwise of the elongated opening 10 to clear the latter of foreign matter preparatory to the introductionv of the oil, butin the present example, I haveshown a pin 15 secured to the part 9 and projecting into said slot.` In the present instance, this pinis snugly fitted into a hole 16 in the inner part 9, and, asan addi# tional measure of precaution, to prevent the` pin from being dislodged, I have herein provided the same with lateral indentations 17,

into which spurs 18, formed of the metal of the surrounding part 9, may be ldriven by a suitable implement, thereby to interlock with the pin and prevent the same from drop? ping out.

If now, when the devicefis closed,.there arek any accumulations of dust, dirt orother l.

foreign matter in the outer opening 10,`when thek outer part 8 is turned to expose the inner opening 11 for the introduction of oil,

the pin 15 will traverse the outer opening and clearsuch opening of the accumulation of foreign matter, so that there will bel no danger of its entering the opening 11. The

pin 15 performs two other functions,-tirst,

it coperates with the slot 10 to limit the relative movement of the parts 8 and 9: and second, itprevents separation of said parts. y

If desired, there may be providedsuiu able means tending' to resist turningmove-v ment of one part upon the other, and in the present example, I have shown for this purpose a spring 19 bearing at one end against the inner. face of theouter part 8. The other end of this spring bears against a cap 20,2

which closes the outer end ofthe passage 12. This spring tends tourge the part 8 in an outward direction on'the part 9, and since such movement is prevented by the pin the friction of these parts one on the other serves as an effective means for preventing accidental opening of the'device.

The form of my invention hereinbefore described is particularly adapted for horizontal arrangement, but tlieiorm shown in Figs. 5, 6 and 7, is especially adapted for use in an upright position. Referring to the latter form, I have shown anoiling device comprising outer and inner parts 2l, and 22, arranged to turn one on the other, and provided with normally non-registering openings and 241, which may be brought into registration to permit the introduction of oil therethrough. In this form, the oil is introduced through these openings into a chamber 25, constituting` a reservoir formed in aseparate part 26 onto Which the part 22 is threaded. A standpipe 27 mounted in the part 26 and extending into the reservoir4 receives oil from the latter by means ot a wick 28, which feeds the oil by capillary action to passages 29 and 30, by means of which it is delivered to a bearing surface 31. It should noiv be apparent that the inner opening 2li is normally closed by the outer part 21, as shown in Fig. 5, and that when the latter is turned to the position shown in G, the openings 23 and 24 are brought into registration, and in so doing a pin 32 secured to the inner part and projecting into the opening in the outer part clears such opening of any accumulations of foreign matter, and prepares. the openings for the introduction of the oil. In this form, the pin serves also as Va means for limiting relative turning movement ot the parts 21 and 22. Separation of these parts, however, in this example is prevented by a suitable fastening element, preterably in the form of a rivet 33 which passes axially through the parts 21 and 22, as best shorvn in Fig. 7, and thus prevents accidental separation of these parts.

lVhile I have herein shoivn and described two specific forms or embodiments of my invention, and have disclosed and discussed in detail the construction and arrangement incidental to tivo specic applications thereof, it is to be understood that the invention is limited neither to the mere details or relative arrangements of parts, nor to its speciiic embodiments therein shown, but that eXtensive deviations from the illustrated forms or embodiments of the invention may be made, Without departing from the principles thereof. p

I-Iaving thus described my invention, What I claim and desire by Letters Patent to secure is:

l. In an oiling device, the combination of inner and outer relatively-rotatable co-aXially-arranged parts having normally nonregistering openings which may bebrought into registration Jfor the introduction of oil,

the opening in the outer part being elongated and formed substantially concentric with the common axis of said parts, said inner part presenting a reservoir entirely therein, and means carried by the inner part adapted to traverse such elongated opening to clear the same of lforeign matter preparatory to the introduction of oil.

2. In an oiling device, the combination of an inner part provided with an oil passage and an opening communicating therewith, an outer part comprising a cup-like cap having a sleeve portion `encircling and mounted to turn on the outside of said inner part and provided With a circumierentially elongated opening, which in one position of said sleeve registers with the opening in said inner part and in another position is out of registration therewith, and means o n said inner part projecting into said elongated opening and traversing the latter When said cap is turned to carry said elongated opening into and out ot registration With the opening in said inner part.

` 3. In an oiling device, the combination of an inner part provided with an oil passage and an opening communicating therewith, an outer part comprising a cup-like cap having a sleeve portion encircling and mounted to turn on said inner part and provided with a circumferentially elongated opening, which in one position oi' said sleeve registersrvith the opening in said inner part and in another position is out of registration therewith, and means on said inner part pro liecting into said elongated lopening and traversing the latter when said sleeve is turned to carry said elongated opening into and out of registration With the opening in said inner part, saidmeans also limiting the turning movement o'f said cap and preventing said cap from being Withdrawn from said inner part.

In an oiling device, the combination of inner and outer relatively movable parts having normally nonnregistering openings Which may be brought into registration to permit the introduction of oil therethrough into the inner part, said outer part compris ing a cup-like cap mounted to turn on the inner part, said openings, when registering, providing a passage extending transverse to the direction of their relative movement, the outer opening being elongated in the direction of such movement, and means carried by the inner part to clear said elongated' opening of foreign matter preparatory to the introduction of the oil, said means being normally positioned at one end of said elongated opening and having a movement 'therein substantially equal in extent to the spacing of said means yand said inner opening.

In testimony whereof I have signed my name to this specication.

Gusravn Gnonouisr.
