Application July 1, 1958, Serial No. 74 ,s s's 13 Claims. 01. soc-90 invention relates to improvements in railroad car journal lubricators and hasfor one object to prov de a lubricator which can be placed in the journal box of the I means, not here illustrated since they form no part of usual type of-railroad journal associated with thelus'ual' brass and wedge and which will maintain without the use of pads, packing or the like, a continuous lubrication of fluid flowing oil on the journal. e

I Another object of the invention is to provide in connection with such a device 'means to limit axial movement of the journal in order to protect the oil sealby preventing the journal from slipping out of the seal no matter what kind of lubrication is used.

Lubrication of railroad car axle journal by the use of packing or waste or pads placed in the box and saturated with oil has long been a source of -trouble and dissatis-' faction. There is a great need for means which makes it possible to lubricate the journal by discharging against the rotating surfaces liquid oil from an oil bath in the bottom of the box. When that is done, however, it becomes essential to provide on the inboard end of the journal an oil seal to prevent splashing out and wasteof the freely flowing bath of oil. Therefore, it is, exceedingly important that axial movement of the journal which would interfere with the effectiveness or perhaps cause damage of the seal be avoided.

My invention comprises in one unit an apparatus which will lubricate the journal and inhibit axial movement of the journal. In a modification of my device, I

use part of the apparatus to inhibit longitudinal movement even though conventional pads, wicks'or waste is 1 used.

:In each case, my'apparatus maybe applied to the journal through the usual trap door in the outboard end of the box without any change whatever in thejournaLthe box or the associated parts, by merely adding to the journal and supporting on the journal myfmechanism.

time to time throughout Other objects will appear from the specification and claims.

. My invention is illustrated more or less diagrammath' cally in the accompanying drawings, wherein Figure 1 is a vertical longitudinal section through a side elevation;

.Figure 3 is a side elevation in part section on an enlarged scale of the outboard end of the bearing and associatedparts;

Figure 4 is a section similar to Figure 3 showing a modified form.

iLike partsare indicated by like characters throughout the specification and drawings.

The'journal box 1 is provided at the front with the usual port adapted to be closed by the pivoted cover 2 through which in the conventional arrangement oil and waste are inserted to lubricate the journal. At the rear end a box is provided with an opening of .much greater diameter than the axle 3 and encircling that opening is a pocket 4 adapted to be filled with any suitable packing tion of the periphery of the journal, having a plane face to limit by contact with the inner face of the collar 6 outboard movement -of the lower portion of the drive i the present invention.

The journal is integral with the axle at the end there of, is of smaller diameter than the axle and terminates at its outer end in a collar 6, there being a shoulder 7 at the. inner end of the journal where. the diameter increases from the journal diameter to the axle diameter. The brass 8 rotates on the journal. -9 is the wedge interposed between the brass and the top of the journal box in the usual way. All these-parts are standard and usual in railroad practice.

A light sheet metal spring bracket 10 having a central pocket 11 contains a. coil spring 12 which seats at one end in the bottom of the pocket 11 and at the other end on a spring pivot 13. The spring pivot 13 rides on the axle insert 14 which is seated in the usual countersink hole in the endof the axle. A pivot extension 15 ,extends outwardly from the spring pivot 13 projecting through an aperture in the bottom of the cup 11.

Carried by'top of the spring bracket 10 is a spacer bracket 16 arcuate in shape as indicated in Figure 2 and "inwardly flanged at 17 to support the bronze thrust block 18, which block rides on the journal, being arcuate to fit it and also engages the inner face of the collar 6. Fingers 19 extend inwardly along the axle below but adjacent to the brass.

- Carried by the lower portion of the spring bracket 10 is the lubricator drive bracket 20 which extends inwardly to a point'behind the collar 6. The brackets 16 and 20 slots make it possible to adjust the brackets radially to fit the journal.

Lubricator'drive bracket supports a guide block 2 4,

preferablyof bronze, arcuate to contact the lower porbracket 20.

The drive bracket 20 is pocketed at to support the 7 ball bearing 26on which is rotatably mounted the drive wheel 27 of steel and the lubricating wheel 28 of rub her so that contact of the drive wheel 27 with the inner face of the'collar or flange 6 will, as the journal rotates,

. cause rotation of the lubricating Wheel, thelubricating' wheeljbeing immersed at its lower periphery at least in' Proper spacing is the'oilbath 29 in the journal box. accomplished by the use of the removable spacer block 30 to insure that the thrust block 18 and the drive wheel 27 will both'be in contac't'with the inner face of the collar 6, being held thereagainst bythe spring 12 to in- 1 sure that the spring'bracket remains parallelism with the end face of-the journal.

, so journal box with parts omitted showing the journal in The thrust block 18 being interposed between the inner face ofthecollar 6 and the end of the brass 8 limits inward longitudinalmovement of the journal and if as is frequently the case the collar-16 is worn away before the lubricator is installed, all thatis necessary. to' insure contact of the thrust block and the drive .wheel 1 with the innerface of the collar is to use a spacer of greater thickness.

The lubricating wheel is pocketed at 31 with weep holes32 so that even Whenthe car is at rest, if the level of the oil. bath .is below the wheel fin 33,-oil can still runinto the pocket 31 through weep hole 32 so as-to; be available for discharge assoon as the car rotates. The fins 33 and 34 about the periphery of the wheel thus one or both being immersed in the oil Will always be available to flow oil diagonally inwardly and upwardly against the under surface of the journal. The axis of rotation of the wheel will be inclined to the journal axis.

In the modified form shown in Figure 4 the lubricating wheel and the drive wheel are omitted side of the journal a spacer bracket 35 quite similar to the drive bracket 20 carries a lower thrust block 36 balancing the thrust block 18. In this case, lubrication may be by any other desired means but the thrust block 18 is still available to inhibit axialniovement of the journal.

The use and operation of my invention are as follows:

The spring bracket and the drive and spacer brackets associated together define an adjustable yoke or spider which masks the end of the journal, encloses the journal collar and yieldingly frictionally engage. the inner face of the collar. This yoke or spider is by relationship with the brass held against rotation and so ispositioned in the journal box by its contact with the journal and the brass alone. This yoke is axially adjustable to compensate for variation in the axial thickness of the journal collar and furnishes a positive spacing means to inhibit by contact with the journal brass excessive axle journal displacement.

At the same time or separately the yoke supports and maintains in working relationship with the journal itself a lubricating device which consists of a single rotating member driven in response to the rotation of the jour-,

nal and adapted to throw lubricant from an oil bath in the bottom of the box upwardly against the journal surface outside the brass to insure lubrication of the journal. The yoke is adjustable radially to compensate for variation in journal diameters, is adjustable axially to compensate for variation in journal collar axial dimensions and a single size of assembly by the use of a plurality of spacers may be applied to a wide range of journals with respect to initial dimensions or dimensions after wear.

' In order to avoid excess oil flow, it will be understood that after oil has leaked through the weep hole 32 and has been thrown out, then as the lubricator rotates at high speed oil will not have time to enter the pocket and the oil thrown out will be that oil adhering to the surface of the rubber lubricating wheel. Thus excess oil discharged at high speed is avoided.

I have illustrated a single lubricating wheel at the lowermost point of the journal but if desired, a plurality of such wheels could be used without departing from the spirit of my invention.
