FLANGE LUBRICATOR.

Application filed December My invention relates to improvements in flange lubricators for wheels, and more par ticularly to lubricators for use in lubricating the flanges of the wheels of locomotives, steam, electric and other cars, etc.

My invention consists in the several features, and in the construction,combination and arrangement of such features as more fully hereinafter described and claimed.

The object of the invention is to thoroughly and constantly lubricate the flanges of the wheels of a locomotive or car, especially when the wheels are travelling on the curved portions of a track, as very little, if any, lubrication of the flanges is necessary when the wheels are travelling on a straight track.

A further object is to dispense with the use, as a lubricant, of solid stick grease, and

thick grease of all characters which have many disadvantages, and substitute oil therefor as a lubricant.

A further object is to provide a flange lubricator for wheels which will cause the oil or lubricant to be automatically fed to the flanges of the wheels by means of the lateral or 'sidewise movement or play of the truck or engine frame and also the latera1 movement of the wheels between the rails during their travel on the track.

A further object is to provide a flange lubricator for wheels which will operate continuously and automatically and require no attention or care except the keeping of the lubricant receptacle constantly supplied with oil or lubricant.

A further object is to provide a flange lubricator for wheels having a Wick or brush with means for keeping the same constantly and evenly pressed against the flange of the wheel and also means for constantly supplying the brush with oil.

A further object is to provide a flange lubr cator which will entirely eliminate the possibility of the oil or lubricant being spread onto the tread of the wheel, and which is mounted in such manner that when the flange of the Wheel comes in contact with the lubricator it does not cause an excessive amount of oil to be spread on the flange of the wheel.

A still further lubricator for expensive and 5, 1922. Serial No. 604,992.

of order even with hard usage, and which operates easily and silently, thereby} obtaining a'maximum effectiveness.

The invention consists in the several features and in the construction, combination and arrangement of such features as more fully hereinafter described and claimed.

Referring to the drawings Fig. 1 is a side view in elevation of my invention.

Fig. 2 is a central longitudinal sec'tion.

Fig. '3 is a vertical section taken on the line 22 of Figure 1.

F 4: is a detail section of the sleeve.

Fig. 5 is a detail section of the plunger.

In the drawings, in Which similar reference characters denote similar parts throughout the several views, 1 represents the flange lubricator, in which oil is to be used as the lubricant instead of grease, 2 the oil receptacle or container which is mounted at the top of a vertical pipe 3 and is provided with a closure 4. V

A horizontal casing 5 is provided, having an upwardly extending interiorly screwthreaded projection 6 in which the lower end? of the pipe 3 is screwed. 8 being a series of oil inlet or, strainer openings in the bottom of I the projection 6, through which oil is fed to an interior chamber 9 of the casing 5.

The outer end 10 of the casing 5 is provided with interior screwthreads 11, and a barrel or sleeve 12 is mounted in the chamber 9 and is PIOVldGCl'Wlljl'l a head 13, having screwthreads 14-, which engage the screwthreads 11 and hold the barrel in place. The barrel 12 is reduced in diameter from a point'15 at the rear of the head 13 to the extreme end 16 thereof and adjacent such end a pin 17 is mounted. Telescopically mounted to slide freely in the barrel 12 i s-a hollow plunger 18, which is provided wlth upper and lowerlongitudinal slots 19 and 20,.respectively, through whichthe p n 17 passes. and through which the oil enters the interior of the hollow plunger from the container 2, through pipe 7 andthrough the series of inlet openings 8.

The inner end of theplunger 18 is provided with an enlarged head 21 having a suitable paclring ring 22in order to provide a tight joint'between the interior chamber 9 of the casing 5 and the head 21 of the pl nge a Justfbey nd-the head 21 the plunger is providedwith an exteriorly screwthreaded projection 23, and 24 is a wick or brush engaging the screwthreaded projection and 25 is a sleeve or casing slidably mounted in an aperture 26 in the ,inner end of the casing 5, which surrounds and encloses the ,wickor brush 24, its inner ;end abutting againstjthe head 21 and its outer endbeing ;incl1 ned or formed at an oblique angle as atj21 in order to conform to the inclination of the iflange of the wheel.

In order, to retain-the brush in constant contact with the flange of the wheel a helical spring 27 is provided located in the interior of the barrel 1 2, intermediate the head 13 of the barrel and theouter end28- of the hollow plunger 18. r

' In operation, the oil flows from the oil container 2 down the pipe 3, through the series of inlet openings and strainers 8 until iit ifills the'chzimber-Q'ofjthe casing'5, flows through the slots 19 and 2010i the'plunger and fills the interior of; the same and also the barrel 12, 'andtheouter end-21 of the sleeve25 and .;the wick or-brush 24 continually contacting and bearing tightly against the flange of the wheel, the forceof the contact being regulated by .the strength or tension of thehe lical springr27. iVVhen the lat eral .sidewisemoyement or play of the wheel or wheels causes the sleeve 25 and :barrel 12 to be pushed or moved inward, against the pressure .or tension ofthe helic'alspring 27 the oilcontained inthe chamber 9 is forced through ,the' slots 19 and- 20 into the interior 'ofthe hollow plunger 18, by the pressure on .the'oil of thehead 21 of the plunger, and the oil'is forced by such pressure from the ,hollow vplunger into and lengthwise through the bristles of thebrush, or the wick 1 tron-lend to .end which spreads theoil evenly on the flangeofthe wheel.
