This invention relatesto oiling devices and has particular reference to an air line o1ler adapted to be atta'ched'to a pressure fluid supply line leading from'a source of supply to a fluid actuated machine, such as a rock drill or the like; l r a Anobject of the invention is to'supply lubricant in suitable quantities and in a properly atomized state to the workingiparts ofa fluid actuated rock'drill or other machine thus actuated, through the agency of the pressure fluid flowing through the supply line.

Other objects will be in part obvious and i i in part pointed out hereinafter.

' In the drawings wherein similar reference corresponding parts numerals designate throughout, V l 7 Figure 1 is a sectional elevation of an oiler constructed in accordance with the practice of the invention, and Figure 2 is a transverse View takenthrough Figure 1 on the line 22 looking in the direction indicated by the arrows. V

, Referring to the drawings, 10 designates a casing which, in this instance, is of cup shaped form having a hollow projection12 in its closed end. The open end of the casinglO is threaded as at 14 for the reception of a head 16 andthreadedly engaging the head 16 and the hollow projection 12 of the casing are sections 18 of an air line through which pressure fluid is conveyed to the machine intended to'be actuated. I 1

Extending through the interior of the ms and at the other end in the hollow projection 12 is a tubular member 20 which divides the casing into a passageway 22 for pressure V fluid and a reservoir 24 for oil. The oil may be admitted into the reservoir 24 through an opening 26 in the casing and this opening may be normally sealed by aplug 28.

Suitable means are provided for admitting pressure fluid into the reservoir 24 to create a pressure on the surface ofthe oil and also ing 10 and secured at one end in the head 16 tures in the tubular member 20. The apertures 32 are? preferably located in the tubular member 20 so thatthe plug will be I positioned. midway between the head 16 and the closed end of the casing lOwhen the parts are assembled. p l y: x The'plug 30 isprovided witha pair of Ion?- gitudinally extending passagesgland 36 and 1 to provide communicationbetween'these pas sages and thepass'ageway22, ports38 and 89 are formed in the plugin such position that they will lieon the axis; of the tubular. member 20 when the plugBOis in position therein.

The passages 34 and36are alsoadaptedto i r A Y c communicatewith the reservoir 24andt0 c5 this end ports 40 are formed inthe plug 30 at each end of the'passagesifl and 36. The

ports 40, are preferably located in the plug 30 so 'thatthey will lie on eitherside' of the tubular member 2O adjacent its periphery when the plug is in position therein. -To ink dicate the position ofthe ports relative to the tubular member-20,' 'a,s1ot[42"may be formed in one end of the plug 30 and this slot 42 may also serve to rotate the plug'in the tubular member '20 before assembly in the casing 10. p V

' To insure delivery of the oil in suitably qat'omize'd state to the passageway 22, the oil in'the reservoir is preferably separated into a thin filmbefore being conveyed to theipassageway. Accordingly, a double-sided plate Mywhichmay be a sliding fit on the tubular T member 20 ,is positioned thereon and maintained againstrotatiom and [longitudinal L5 movement by means of the plug 30 extending throughsuitably formed" apertures 46 therein! The plate 44 is also providedwith pasv sages 48 arranged in such-position relative to" the ap'ertures'tdthat they will communicate v V with the ports 40' in the plugBO. -On" either V side ofthe plate 44 are sideplates 50 which r i may be secured to the tubular member 20in any suitable"mannerfsuch as by press fitting, and to this; end having proj ection's'152 forn'a'ed thereon to insure a substantial bear ingsurface."

The side plates 50 are preferably arranged j I e "on the tubularmember 20 insuch close rel'ation to thecentral plate l l that there will be but a slight clearance, as at 54, between these members sothat the oil entering the spaces 54 between the plates will be of substantially film-like form. 7 7

The operation of the device is as follows: lVith the .oiler' connected to the pressure fluid supply; line 18 .so" that the air will enter, for instance, at the head 16and will flow towards the projection 12, a portion of the air will en ter the port 189 V and pass throng-hethetpass'age 36, ports. 40and-passages448 toienter the -reser-'-..

voir 24 throughthe space 54 between the plates 44 and 50.2.

The pressure fluid thus entering the reservoir will create a pressure thereiu'equalto the pressure in the main sup 1y line. 7 If then the in achine,zsucli ,as a; roci drill-which s intended to be operated, is set in operation,
