9 Ciaims. (Cl. 308-88) The present invention relates to journal lubricating devices, :and in particular to such devices having novel means for properly locating and anchoring the elements thereof in the journal box.

It is a principal object of the present invention to provide a new and improved journal lubricator which is readily installed in a journal box and, when installed, properly locates the elements thereof with respect to the journal, and insures an even distribution and application of lubricant from the well to the journal under all operating conditions.

Another object is to provide a novel journal lubricator wherein the lubricating element resists disintegration under operating temperatures up to 400 F. and prevents journal seizure in temperatures as low as 60 F.

Another object is to provide a, novel journal lubricator comprising an assembly of a lubricating pad in contact with the journal, a llet seal and lubricator, and a journal box lid seal, with each element properly located with respect to the journal box and the journal.

Another object is to provide a novel journal lubricator which may be anchored in the journal box by a single bolt.

A further object is to provide a novel journal lubricator which, when anchored, firmly presses a fillet seal and lubricator against the inner wall of the journal box and holds a lid seal in position to be engaged by the journal box lid.

Still another object is to provide a new and improved journal lubricator assembly which has a visual oil level gauge incorporated therein.

Still another object of the invention is to provide a novel journal lubricator which is easily removed for inspection and repositioning or replacement, if necessary.

Other objects and advantages will become apparent from the following description taken in conjunction with the accompanying drawing, wherein:

Fig. 1 is a perspective view of a journal box and journal with portions of the box cut away to show the journal lubricator of the present invention properly installed;

Fig. 2 is a longitudinal section through the journal box and lubricator, but showing the pad of the lubricator which is in engagement with the journal in full lines, and may be considered as taken along'the line 2-2 of Fig. 3, looking in the direction of the arrows;

Fig. 3 is a transverse section and may be considered :as being taken substantially along the line 3--3 of Fig. 2, looking in the direction of the arrows;

Fig. 4 is a section taken substantially along the line 4--4 of Fig. 2, looking in the direction of the arrows, and showing the mounting of the journal box lid seal; and

Fig. 5 is a detail sectional view showing the connection between the mounting strip and the iillet seal and lubricator.

In the drawing, the reference character indicates in its entirety the novel journal lubricator of the present invention, which is located in a journal box 12, through ice the

inner walls

14 and 16 yof which extends a journal 18. The journal box has the conventional access opening at its outer side or face, which is closed by a conventional spring biased lid 22.

The journal lubricator 10 includes a journal lubricating section 24, a llet seal and lubricating section 26, and a lid seal section 28.

The journal lubricating section 24 comprises a sheet of porous fibrous material 30 which preferably is a silicone impregnated wool felt. Other materials may be used, but it has been found that the silicone impregnated felt is especially desirable inasmuch as it reduces the friction between the felt and the journal, effecting a reduction in operating temperatures and an increase in the resistance of the felt to disintegration from heat up to approximately 400 F., and precludes the possibility of journal seizure in temperatures as low as 60 F.V The felt sheet is folded or bent to provide a base segment 32, and a journal lubricating segment 34 which extends upwardly and at an acute angle from the base section 32,

' the latter being positioned in the lubricant well 31 of the journal box. At its upper and outer end the lubricating section 34 is bent back upon itself to provide a spacing pad, or the like, 36, the function of which will become apparent hereinafter. t

The journal lubricating segment 34 is biased rmly into contact with the journal 18 by a plurality of resilient biasing members 38. Each of the members 38 includes a basev leg 40, a lubricator segment leg 42, and an acute angle member 44. The base leg 40 is secured to the angle 44` by a pair of rivets 46, and the leg 42 is similarly secured to the angle by a pair of rivets 4S. The angle is relatively rigid as compared with the legs 40 and 42, which may be made of spring steel. Each leg 46 is secured to the base segment by a single heavy wire clip or staple 50, and similarly each leg 42 is secured to the spacer pad 36 of the lubricator segment 34 by a single Wire clip or staple 52. In this manner the members 38 are secured, respectively, to the base segment 32 and to the lubricator segment 34, and tend to separate them, thereby rmly pressing the lubricator segment 34 against the journal 18. The spacer pad 36 insures that the journal is contacted over a. substantial portion of its circumference as shown in Fig. 3.

Underlying the legs 40, and overlying the base segment segment 34 toward the front or open end of the journalI box 12. The strip 54 is secured as by rivets 56 to each leg 40 of the resilient elements 38, there being two or' the rivets S6 for each leg 40, to prevent angular offsetting of the strip and the leg 40. At its forward end the mounting strip 40 overlies a T-shaped projection 58 of the base segment 32. At its inner end the strip S4 is secured by the rivets 40, not only to the inner of the legs 40, but also to an angle 58 having an upstanding llange 60 which is secured by pairs of rivets 6.2 to di agonally extending fingers 64, the angle between the fingers being approximately The llet lubricator and seal 26 comprises an arcuate pad 66 formed of the same material as the sheet 30. The pad 66 is faced at the side thereof which bears against the journal box wall 16 and against the fillet 68 between the journal 18 and the axle shoulder 70, with a wear resisting sheet 72 made of a material not attacked by lubricant, such as neoprene. The pad 66 is secured to the` flange 60 and to the outer ends of the fingers 64 by a pluguard and oil seal `75 which, .together with. the fillet seal plurality of resilient biasing` 3 and lubricator 26, prevents the escape of lubricant from the well 31 of the journal box and the entry of dirt along the shoulder portion 70 of the axle.

The T-shaped projection 58 from the base segment 32 of the sheet 30 preferably is integral with the sheet but, it desired, may be made separate. It has at its outer end a cross pad 76 which, when the lubricator is properly positioned in the journal box, extends the width of the journal box as seen in Fig. 4, and its outer lip, as seen in Fig. 2, is at the edge of the inclined front well wall 27 to form the lid seal 2S. A transverse strip 78 overlies the cross bar pad 76 and is secured thereto by a plurality of rivets 80 and by a heavy wire clip 82. The wire clip S2 also passes through, and fastens to the pad portion 76, a relatively heavy gauge metal anchor plate 84 which is secured to the strip 78 by rivets S6, and to the outer end of the mounting strip 54 by a plurality of rivets 88. The plate 84 is substantially stiffer than the

spring steel strips

54 and 78 so as to resist bending.

The anchor plate S4 has a medial longitudinal slot 90 formed therein which coincides with a similar slot 92 in the cross bar pad 76. These slots afford longitudinal adjustment of the lubricator 10 and accommodate a carriage bolt 94 which is passed therethrough and through a specially drilled hole 96 in the journal box wall 77 adjacent the opening 20. The carriage bolt also passes through a synthetic lubricant resisting rubber washer 97 to assist in sealing the drilled hole in the journal wall 77 against the leakage of lubricant.

At the inside of the journal box the bolt 94 is fitted with a tempered spring steel periphery dome washer 100, and at its outer end is fitted with a lock nut 98. When the nut is drawn tight small projecting teeth around the hole in the dome washer 100 will embed themselves in underside of the the bolt head, and the dome washer lil() in cooperation with the tightened lock nut 9S will exert a back pressure on the anchor plate 84 so that there is a lirm and tight anchorage of the lubricating device 10, and no amount of car vibration can loosen its mounting in the journal box.

It should be noted that when the journal lubricator 10 is properly anchored, the base segment 32 is in the well 31 of the journal box 12, the fillet lubricator and seal 26 is pressed firmly against the wall 16, and the journal lubricator 34 contacts the journal 18.

A visual lubricant level gauge 102 is secured as by a heavy wire clip or staple 104, to the stern portion of the T-shaped projection 53 at the outer end of the base segment 32. This visual oil level gauge 102 preferably is ma'de of the same material as the sheet 30. lt is desired that the oil in the journal box will be maintained at a level just to cover the visual gauge, although, with the journal lubricating device of the present invention, if there is any free oil in the journal box it will -be fed to the journal lubricating segment 34 and thus insure positive lubrication of the journal under all conditions of operation.

The synthetic rubber washer 97 has an additional use. Should it ever be necessary to remove the lubricating device 10 and not replace it with one of the same design, the bolt 94 is secured in the hole 96 in the well wall 77 with the washer 97 between the bolt head and wall to seal the hole and prevent leakage of oil from the well 31.

The journal lubricating device of the present invention is installed in a journal box by compressing the journal lubn'cating segment 34 toward the base segment 32 so that the two can be slipped under the outer flange on the journal 18. The tillet seal 26 is tipped under the flange and the journal lubricator assembly 10 is then, with a steady pressure, forced under the flange until the fillet seal comes to rest against the wall 16. In this position the lubricator segment 34 will underlie the journal 18 and its outer edge will be within the flange at the outer end of the journal. The lid seal pad 76 will have its outer edge at the outer edge of the lip forming the bottom of the well, and the hole 96, if it has not already been drilled in the journal box well wall 77, should be drilled at this time. The carriage bolt 94 fitted with the dome washer 100 and sealing Washer 97 is inserted through the hole 96 and, when an adequate pressure has been applied to the seal 26, the lock nut 98 is tightened. The flexible spring metal mounting strip 54 places pressure upon the fillet lubricator and seal 26 to seat the latter (Fig. 2), thereby to prevent oil from splashing out of the inner end of the journal box.

The lubricating device 10 may be readily removed from the journal box by removing the carriage bolt 94, depressing the journal lubricator segment 34 so as to clear the flange, and pulling the end of the lubricator pad so that the assembly slides under the flange on the journal. The lubricating device 10 may be relocated in the journal box or replaced as hereinbefore described.

From the foregoing it will be appreciated that the objectives which are claimed for the present invention are attained by this structure.

While a preferred embodiment of the journal lubricating device constituting this invention has been shown and described, it will be apparent that numerous modifications and variations thereof may be made without departing from the underlying principles of the invention. It is therefore desired, by the following claims, to include within the scope of the invention all such variations and modifications by which substantially the results of the invention may be obtained through the use of substantially the same or equivalent means.
