21 Claims. or; 30 -443 The device disclosed in the copending application of Rudolph W. Miller and myself, Serial No. 486,766, filed February 8, 1955, the disclosure of which is incorporated by reference in interests of brevity, remedies many'of the defects commonly found in lubricators of this type} Generally speaking, this device includes a waste blanket looped 7 about a resilient core. The lubricatingdevice herein dis closed is an improvement over the device'of said copending application.

The lubricator disclosed in said copending application provides a number of improvements over conventional journal box'packing packages, one of the most important being that the unit can be installed without jacking the journal box assembly. The lubricator of the present ap plication retains the inherent advantages of the device of said copending application, while at the same time providing additional improvements.

One of the principal problems in this art is that the packing packages tend to shift to one side of the journal box-and towardsthe edge of the bearing under the action of the rotating journal. In the lubricator of said copending application, the seam of the waste blanket is at the side of the packing and when thepacking shifts to a position wherein the seamed side of the lubricator is the lower side thereof, a reduced feed results, as the seam reduces capillary action on one side of the packing, requiring that lubricant travel arelatively long path around the other side of the packing to reach the journal. As experience has shown that it is impractical at thepresent state of the art to prevent shifting of the lubricator, it is necessary to insurethat the lubricator provides adequate lubrication even when it is in shifted position. V

Accordingly,"it is a principal object ,of my. i v'ention to provide a journal box packing of the packagetyp ede signed to provide capillary feed paths of minimum length which lift a maximum amount of lubricant to the journal, regardless of the position of the lubricator in the journal box. I

Another object of the invention is to provide a journal box packing that lifts lubricant in substantially a straight line between the lubricant, reservoir and the journal vand thus provides a capillary -feed1path of-m-inimurn length.

Still another objectof the invention is to vprovidewa journal bo'xpaick-in'g whichlisjshaped to permit excess lubricant to drain backinto the lubricant .reservoi'rduring rotation of the journal, but at the same time is arranged ted rates Patent ,7 to utilize a maximum amount of this lubricant toprovide athoroughly saturated journal contacting or lubricating surface.

A further object of my inventionis to provide a new design for packing packages including waste blanket means encircling resilient core means in which an' improved form of core harness is employed to secure the core means to the blanketmeans.

Still a further object ofthe invention is to provide a journal box packing package which is shaped to catch a considerable portion of the surplus oil which drips from the journal and thus increases the film of oil applied to the journal during rotation, and yet which is formed to preclude the drainage of oi l' out of the rear of the jo rn bQ Yet a further object of the invention is to provide a packing package thatis sufiiciently flexible to be installed without jacking the box.

Other objects, uses, and advantages will become apparent upon aconsideration of the following description of a preferred embodiment of my invention.

i General description Referring now more particularly ,to' Figures 1 and 2 -Ih d w n .rs et sea m r s y nd sets I i V a conventional journal box {on a conventional axle journal WI h a .lphes st s ss war n to the e en invention, generally indicated by reference numeral 12,

P tent d Mann 1% in place between the lower portion of the journal and the bottom of the journal box in what is commonly referred to as the oil or lubricant cellar of the journal box.

The package forming the illustrated forms of packing generally comprises (see Figure 3) a pair ofattached laminated waste blankets or envelopes 14, handle means 16, a plurality of generally similar, relatively flat resilient pads 20, and a pair of H-shaped straps 22 especially adapted to securely fasten the pads 20 within and to the envelopes 14. These elements form the twin lobes of the packing and are more particularly described hereinafter.

The waste blanket adjacent the journal when the package of the presentinvention is positioned as described above.

The envelopes 14 are shaped from blanks that may be of the type described and illustrated in my copending applications Serial No. 367,321 filed July 10, 1953, and Serial No. 419,029 filed March 26, 1954, now Patents Nos. 2,762,667 and 2,801,138, respectively, though preferably they are modified as hereinafter described. The disclosures of these copending applications are hereby incorporatedby reference in the interests of brevity. I The envelope or blanket blanks of the illustrated embodiment of the invention (see Figures 7, 8, and 9) each comprise a relatively thick layer of carded waste 24 interlaced with a pair of woven carrier cloths 26 in the form of open weave laundry bag cloth in the illustrated embodiment, and a relatively thin layer of waste 28. The cloths 26 are preferably woven from strands or yarns made up of high capillary action material, suchas vicara, cotton, or a mixture of both.

In accordance with the description of the aforesaid applications, the three layers are thoroughly fastened together by passing them through a hooking machine of the type, for instance, illustrated in Patent No. 2,672,673, granted March 23, 1954. As the layer or layers of waste and fabric go through the machine, they pass over a hooking plate, Where they are subjected to the action of a multitude of hooked needles which reciprocate up and down. As the layers of waste and fabric go through the action of the hooked needles, many of the waste threads are caught by the hooks and pulled downwardly and looped through the remainder of the upper layer of Waste, through the fabric, and the lower layer of Waste, and formed into loops below the fabrics. In some instances, the waste threads will be caught near the top of the upper layer-in others, deeper into the layerbut the overall effect is to hook individual threads of waste through the mass of waste and the fabric and not only fasten those particular threads but associated threads into a blanket in which, generally speaking, all the threads are made fast against being pulled out in service.

During this hooking operation the weave of the carrier is tightened or shrunk by the interlacing of the threads which are thereby brought into intimate contact with the threads of the cloth in such a way as to promote ready transfer of oil from the carrier cloth to the waste threads. The thinner layer 28 may be formed entirely by hooking threads through the fabrics 26, or it can be in part formed by feeding a thin layer of carded waste under the carrier cloth before reaching the booking machine or in a supple mentary or preliminary hooking machine. I

Moreover, the exposed surface or side of the thinner layer is preferably treated and coated with an adhesive 29 to fasten at the under side of the blanket all threads that go through to the under side-of the blanket. Additionallyrthe adhesive forms a membrane-like barrier directly under the journal for preventing lubricating oil from draining or soaking through the blanket. It m y also be mentioned that the adhesive stabilizes the blanket in that it prevents undue stretching or bunching of the material comprising the blanket under the action of the rotating journal; thus the relatively stiff layer of adhesive provides a strengthening and reinforcing effect which materially lengthens the useful life of the packing.

The adhesive may comprise any appropriate material, many of which are known as rubber base cements. They may be used in powder form, sheet form, or liquid. Many of the so-called synthetic rubbers are appropriate, for example, Hycar latex No. 1552, type OR-25, made from petroleum by B. F. Goodrich Chemical Company, of Akron, Ohio, and thickened with a 12% ammonium casein solution. Several suitable types are specified in the aforementioned applications, and other suitable synthetic rubbers are described in Materials Handbook by Brady, 1944, McGraw-Hill, page 523.

Referring'to Figures 10, 11, and 12, two blanks are employedin making each packing of the illustrated em-- bodiment ofthe invention, each blank comprising an. envelope or blanket 14. At the same time or after the blanks have been made from the sheet material manufactured as described above, they are each shaped in the form indicated in Figure 10. As shown in Figure 10, the edge 30 of each blank (which forms the front end of each blanket 14) is squared with the edges 32 that form the sides of the blanket 14. The rear edge 33 of the blank opposite edge 30 is notched or indented as at 34 and, in accordance with the present invention, the edges 32 are provided with rounded notches 36. The blank is also formed with a central perforation 38 for a purpose hereinafter made clear. In the illustrated embodiment, the perforation 38 is generally quadrilateral in configuration.

After each blank is formed, the edges of the blank are bound as indicated at 44) in Figure 11, which may be done by putting the blank through an edging or edge stitching'machine. Preferably the blank is bound about the perforation 38 by suitable stitching 39. The blank is also preferably stitched longitudinally thereof where indicated in dotted lines at 41 in Figure 11 to further secure the individual threads of the waste blanket in place. Incidentally, the blanks are preferably cut from the sheet material from which they are formed in such.

a manner that the individual waste threads will extend transversely of the packing and also of the journal when the packing is in the position shown in Figures 1 and 2 (see Figures 3 and 4).

Each blanket or envelope 14 is provided with a handle 16 atone side thereof. The handles 16 each generally comprise a metallic end piece or buckle 42 secured to a fabric holder or strap 44 which is stitched to the envelope or blanket where indicated in Figure 11. The metallic end piece of buckle 42 is positioned adjacent the edge 30. of the blanket or envelope 14, which is the outer end thereof.

Two envelopes or blankets 14 are then positioned adjacent each other with their layers 24 in contact, and theyare stitched together as and Where indicated at 46 in Figure'll. It will be appreciated that this stitching is along a straight line that extends centrally of the blanks andsubstantially coincides with the longitudinal axis of the packing when the same is positioned as shown in Figures 1 and 2.

V The resilient cores The resilient cores of the illustrated embodiments of the invention comprise a plurality of relatively flat, resilient pads 20, each of which is composed mainly of a stack of like parallel tubes 50. Tubes 50 may be separately extruded, or may be integrally extruded in, for instance, the formillustrated, wherein each tube has a wall portion 51in common with other tubes 50 and integral with thern'at adjacent corners as at 52. The individual pads 20 are of a cellular structure which is entirely integral;

dea ness ii-istr ibutioh =of the material comprising same makes it possible to have an 'extremelyliglit, spring'y element with a astrongrresis'tance to deforming under pressure and a high recovery upon release, even after being compressed for a long time under adverse temperature conditions. The tubes 50 are preferably made "from a suitable lubricant resistant and impervious material, "such as synthetic rubber. V

Pads corresponding 'to those shown -:in Figure 3 can be made in a great variety of forms. Almost any polygonal form can be extruded, whether regular, irregular, right-angular, :or'otherwise. 7 generally :pdlygonal forms which "lend themselves to the application of the invention, the equilateral hexagon discloses suitable material forrnaking :the =:-pads. The

disclosurerof said application is incorporated herein by reference. in =the interests of brevity.

As se'enfliniFigure 6}11'16 ends of ithelpads 20 maybe trimmedv diagonally of their lengths for a purpose here inafter made clear. "Alternately, the pad ;ends' may be trimmed ;as'-diagnammaticall y indicated in Figures 16 and 51-7- While the multitubular :pads illustrated in Figures 3 and 'l-6 are;a;pre ferred type of core, similarlyshaped pads of sponge frubber, natural :hair or fiber glass would also be satisfactory. H

' The pads 20 and the straps 22 are'arranged generally in accordance with -the;invention described in the said copending application Serial No. 486,766. speaking, two of the pads 20 are :positioned on either Of the many polygonal and Generally 6 tapes, but including a trapezoidal flap :68. These configurations are provided to substantially close an the open ends of the looped blankets. In the illustrated em-'- bodiment of :the invention, a supplementary securing strap 66 ,is secured to each flap 68 of rear tapes 60 by stitching 69 (see Figure 12). j

Referring to Figure 12, after the pairs :of blankets 14 have" been stitched together as indicated in Figure 11,

'one end of the rear leg 59 of 1a securing strap 22 is secured to one side of the rear end of each blanket 41 w and one end of the front leg 59 thereof is secured to the front end-of said blankets in the manner indicated in I Fig re 12. Preferably tapes 60 are long enough to be included in this stitching so that one edge of the rear tape 60 and one end of a strip -56'are stitched to the rear side of the blanket 14, and one edge of the front tape 60 and one .leg or" .a' strip 56 are stitched -to the 'front end of the blanket ,14 (see Figure 7 "Preferably, the tapes 60 and the .ends of the strips 56 are secured to the blanket'14 by common stitching 70 (see Figure 7). Supplemental stitching 71 may also be employed (see Figure 12). The

unattached fend of each strap 66 issecured to the front end of each blanket as by stitching 73 (see Figure 12).

When straps 22 have been secured to both blankets 14, the blankets are respectively bent to position their edges 32 adjacent each other and the unfa'stened legs 59 are made fast to the respective blankets by stitching '76 and 7.1. The two pads of each blanket are positioned on either side of the respective strap webs 57 and then the edges 32 of- .each blanket are brought together and are secured together with their edges 32 facing outside .of H-strap 22 and the .whole inserted and secured v to 'a blanket 14ashereinafterdescribed.

The securing v straps The securing straps 22 :are best illustrated more particularly in Figures 3 and 14. Each strap '22 of the embodiment ofthednvention Eillustrated in Figure 3 con1- prises a pair of strips 56 0f a suitable fabric placed' side by side and stitched together at the center and at each end of the individual straps where indicated at 58in Figure -,3. The ends of the strips 56 :are ,;bent away from each other to 'aiposition in which they are :in substantial alignment, and a strip of strong,-non-stretchable cloth tape or its ,equivalentf60 is vsecured to the :angled ends of the stripsi5'6, the :tapes 60 being stitched to both .strips 56 a'sshow'n at 62. Preferably, the area of each strap 22 adjacent its rear end (that is, for instance,

wardly of the lubricator; These edges 32 may be secured together by stitching 75 and by brass staples 72 or other suitable securing means. i As indicated in Figures 4 and 5, a hollow rivet 74 holds the rear edges of the respective blankets together.

.As stated in the aforesaid copending application Serial No. 486,766, the reason for rubberizing the rear ends of --the securing straps 22 is that when a railroad car is on arr-inside curve (with respect to the journal shown in Figures l'and 2), lubricant within the package 12 will be retained therein andzrestrained from flowing out of the journal box overthelips 77 at the rear of the journal box (see Figure 2). 7

-.When the package embodying this invention is to be put to use, it is compressed and worked down under the journal into the position shown in Figures 1 and 2( The notches-36 and the perforations 38 of the blanket 14 are aligned with each other along the transverse axis of the lubricat'or byv the manner in which the blankets are secured together. This permits or provides additional flexibility of the lubricator and allows'the lubricator to ire-installed without having to jack the journal box.

"Once in the position shown inFigure's l and 2 the pads 29 comprising the resilient core of thelubricator holdthe package in place and prevent it from working I out offthe "correct position. Due tothe flatness and the therighthand side of Figure-3) is rubberized with, 'for instance,'-Hycar later, on the inner or-out'er surface there- 'of, -or both, :somewhat as indicated at 64 in Figure '3'.

Saidlatexisa product ofthe aforementioned B. Good rich Rubber Company. I

It will be appreciated from Figure '3 that eachstrap 22 assumes a substantially H-shaped configuration in which the portions of the strips'56 that are connected together 'form :the web 57 of the H and the normally disposed ends form the legs 59 thereof.

.Also, in .the illustrated embodiment, the cloth tapes 60, are .of particular significance. As best seen in Figure 3, :the front tapes 160 each have a :generally quadrilateralconfiguration iwhich respectively :generally conform to the'configuration of the. open frontbr outer ends of the lopped blankets whilethereartapes 60 have asix sided configuration, they being generally similar e-to .-the front,

secure manner in which the blankets 14 are secured together, as well as the relatively flat space enclosed or encircled by each blanket, the tendency of the package to roll out from under the journal and to one side of the journal box, as'distinguished from shifting bodily under the action of the journal, is eliminated. The secure ness of the resilient pad fastening straps 22 also aids in providingthis result.

Figures 13-17 illustrate a modified embodiment of the invention wherein the core securing strap is formed out of a single blank 9!) of a suitable fabric,:r ather than from straps 56 and tapes 6b. The blank Qiiis formed withibehd lines A, B, C, D, and Egforming portions 92,

spective bend lines in the manner indicated in Figure 14 to ioirn the-"securing strap 22A. Thus, the portions :96

and liMya-re juxtaposed by bending theblank along the line A. The portion 92 is then bent toward portions 94 and 106 along line E, the portions 94 and 106 being bent outwardly of the respective portions 96 and 104 along lines C, to juxtapose portion 92 adjacent portions 94 and 106 with the center line 93 of portion 92 adjacent lines C; at the other end of the strap, the por tion 100 is bent toward the portions 98 and 102 along line D, the portions 98 and 102 being bent outwardly of the respective portions 96 and 104 along lines 13, to juxtapose portion 100 adjacent portions 98 and 102, with the center line 101 of portion 160 adjacent lines B. The respective portions of the blank 90 then may be secured together by, for instance, stitching 110. Strap 66 is secured by stitching 73 as described hereinbefore, and adhesive 64 (not shown) may be applied to the inner end of each strap 22A.

The core securing strap 22A formed from blank 90 is preferably secured to the individual blankets 14 in the manner indicated in Figure 15. As shown, the stitching 70 preferably passes through the lavered portions of the strap legs 59. and in addition, supplemental stitching 71 may be employed. (see Figure 12). Preferably, the pads 20A and the strap 22A are so proportioned that the legs 59 of the strap are bent somewhat as shown in Figure 15 when the pads are in place. Moreover, the ends of the pads 26A of this embodiment are trimmed as diagrammatically indicated in Figures 16 and 17. that is. the ends of the respective pads taper toward the center of the lubricator. This relationship substantially eliminates bulging of the core securing strap legs outward y of the lubricator when the lubricator is compressed, and

securely holds the resilient pads in place.

Advantages of the invention One of the most important features of the invention is the center capillary feed provided by the bent portions of the blankets 14, that is, the area of each along which they are secured together. As seen in Figure 1, this portion of the lubricator is disposed immediately under the lowermost portion of the journal. and immediately above the bottom or lowest portion of the journal box. The capillary carriers 26 of these portions of the blankets 14 lie along a. substantially straight line and extend from a position adjacent the lowest portion of the journal box to a position adjacent the lowest portion of the journal. This arrangement provides wick means extending through the center of the packing resulting in an unusually short feed path from the oil reservoir of the journal box to the journal and tests have shown that this center feed arrangement permits lubricant to reach the journal six to seven times faster than in conventional packings wherein the envelope is looped around a sin le core. a

This provision of a short center feed together with the addition of a second woven carrier in ea h blanket 14 provides a substantial increase in the oil film applied to the journal and substantially reduces the time required after long periods of inaction for adequate lubrication of the journal. Even when the packing shifts to the right or left of Figure 1, the feed path remains relatively short. It should also be noted that this center feed feature is obtained by me without sacrificing other advantageous features of the invention, such as installation without jacking the box.

Additionally, the longitudinally extending stitching 4-! shown in Figure ll and the adhesive layer 29 of each blanket make the individual fibers of the blanket fast to the lubricator, thus precluding the possibility of a hotbox. it. will also be observed that by forming the blanket 14 so that the waste threads extend transversely of the journal and longitudinally of carriers 26,.the waste threads tend to supplement the capillary lifting action of the carriers 26.

The configuration of the packing 12 is particularly adapted to prevent draining of lubrication oil out of the rear end of the journal box. As seen in Figure 5, the

notches or indentations 34 of the rear edges 33 of the blankets 14 combine to provide an indentation or reentrant angle in the rear of the lubricator which forms a drain port outwardly of the rear fillet of the journal and permits the excess oil accumulating between the two lubricating bodies formed by the blankets 14 and their respective core means during operation of the journal to drain back to the oil reservoir of the journal box. This prevents the rear portion of the journal from forming with the packing sort of a pitcher spout which acts to pour the excess oil out of the rear of the journal box.

Also, oil tends to return to the oil reservoir through the central packing hole formed by the perforations 38 of blankets 14. r

As seen in Figure 1, the outwardly extending edges of the packing have a peaked or tent-like configuration forming shelf means or wing-like projections that tend to catch a good portion of the surplus oil which drips from the bearing during operation, thereby saturating the area of each blanket 14 at the juncture of the respective blankets and the journal surfaces. This permits a heavier film of oil to be applied to the journal during operation. Excess oil collecting at this portion of the packing drains back to the oil reservoir through the hollow rivets 74 at the rear ends thereof. However, it will be noted that the coating 29 on the inner face-of the blanket acts as a barrier or oil flow inhibitor to prevent drainage from the shelf means to the oil cellar through the contiguous lower flap or wall of the lobe blanket. i

The semi-circular notches or cutout portions 36 on the side edges of the packing not only aid in making the packing more flexible but also permit installation in bolted boxes having internal bosses. These cutout portions not only permit the packing to clear these'bosses, but also help to prevent it from shifting toward the front of the box, since the cutout portions will be received about the bosses.

The harness straps 22 and 22a are particularly designed to hold the core means of each blanket very securely.

In straps 22,'trapezoidal flap 68 of the rear tapes 60 covers the inside corner of the individual resilient pads 20, and the supplemental straps 66 secured to the front of each blanket prevents the pads from shifting to the rearof the packing, especially during installation. Straps 22a are also formed with a flap 68 that performs the same function.

As seen in Figures 6 and 16, the central surfaces of upper and lower pairs of resilient pads 20, which face each other, are somewhat shorter in total length than the surfaces that face outwardly of the lubricator (though only the top pads are shown in, for instance, Figure 6, it is to be understood that the bottom pads are similarly shaped). In the embodiment of Figure 6, the front and rear ends of the pads converge interiorly of the packing because of the manner in which the pad ends are trimmed. This arrangement provides space at each end of the packing into which the strap ends may be pressed, and by making the sides of the straps 22 that are adjacent the supplemental straps 66 shorter than the other sides, bulging of the harness strap ends when the packing is compressed is prevented- If the legs 59 were permitted to bulge, they would come into contact with the journal cellar at the front end of the box 10 and become pinched between the journal and the inside lower wall of the dust guard (not shown) in the rear, with resulting 'u'ndesir-' able wearing of the lubricator. The arrangement of Figure 15 prevents bulging of the strap 22a outwardly ofthe lubricator as the ends of the core. pads 20a form pockets in the legs of these straps and take up' any looseness, and the centrally tapering ends of these pads provide plenty of room to accommodate bulging as the lubricator is compressed.

It will be observed that the package 12 is substantially symmetrical, and that when it is desirable to present anewnsurface against .the journal, .the ,packing may be removed, turned over, and reinserted. Thus, the used surface of .the blankets will'lre facing downwardly .in the journal boxand thehitherto unused waste surface of the blankets will be .in contact with the journal. The package 12 is therefore a two-sided or reversible one with a cation to the journal when movement of the journal again begins. I

During operation of the ,journal, the membrane-like barrier fformed by the adhesive cooperates with. the journal and the 'capillarymaterial to provide a reflux type action on the oil that is applied to thejournal. Assuming that the journal rotates clockwise in the showing of Figure 1, oil drips or is thrown by the journal back onto the upwardly projecting side of .the underlying lobe of the lubricator; since the oil is retained adjacent the capillary material by the underlying membrane-like barrier, it is reapplied to the journal to supplement the oil reaching the journal by capillary action through the capillary material. As rotation continues, the oil film applied to the journal increases until 'a stabilized conditlon is arrived at. The wing-like 'projections'Yformed by the sides of -the lubricator provide positive oil deflectors that catch the oil and prevent it from moving into the space between the packing and the .journal jbox ihousin'g side wall.

-T he handle means 16 makes it relatively easy to remove the package -12 from the journal. The metal or metallic end pieces 38 are formed with an opening adapted to receive a hook similar to that ordinarily found on a boX packers tool, and by which the package may be withdrawn from the journal box.

The stitching -46 illustrated in Figure 11, is particularly adapted to avoid constriction or confinement of the high capillary action material making up the woven carriers 26. It will be observed that instead of employing stitching that runs all the way across the blanket longitudinally of the lubricator, the individual stitchings 46 are spaced apart longitudinally of the packing and extend "transversely thereof. This insures that there will be considerable portions of the woven carriers 26 that are not bound at all by the stitching 46. Also, stitchings 46 are preferably as loose 'as is permitted by the nature of my package.

The foregoing description and the drawings are given merely to explain and illustrate my invention and the invention is no'tto be limited thereto, except insofar as the appendedclaims are so limited, since those skilled in the art who have my disclosure before them will be able to make modifications and variations therein with-. out departing from the scope of the invention.
