Definitions

  • the pad type of lubricator has reduced the likelihood of loose strands of textile material from being drawn upwardly by the journal where .they are trapped between the bearing and eventually ignite due to being wiped dry, and additionally much more effective relay of lubricant to the journal has been realized in comparison to the previous standard practice of waste packing lubrication.
  • the present invention is concerned with a multiple pad lubricator of the foregoing generalized construction, and one of the primary objects of the present invention is to enable a flexibily integrated two-pad lubricator to be used under circumstances where there is an effective relay of lubricant to substantially the entire lower half of the car journal in spite of some separation between the pads in achieving the desired flexibility for ready conformability to the arcuate shape of the journal.
  • Another object of the present invention is to so construct a lubricator achieving the Iforegoing object while accounting for effectively maintaining the lubricator against shifting to the extent that one or the other pad section might be rotated by the journal upward against the bottom' of the bearing.
  • These channel shaped voids are to be lilled by a separate filler of wicking material having loose loops disposed in the channels, and these two loops respectively constitute wicks disposed at the medial center line of the bottom of the journal box and at the nadir point of the journal between the two sleeves, thereby establishing a high wicking rate at the flexible center of the lubricator where normally there would be voids tending to reduce the transfer of lubricant to the journal at this vertical line.
  • the outer vertical sides of the fabric casing are drawn together in such a manner as to define end flaps, and these end flaps are reinforced by heavy cotton duck material to constitute stiifened end sections on the lubricator which will engage abutments ICC i within the journal box to maintain the lubricator in the desired position within limits and insure against undesired shifting of the lubricator within the journal box.

  • FIG. 2 is a perspective view of an assembled lubricator
  • FIG. 3 is a fragmentary side view of the medial section of the lubricator shown in FIG. 2 but with the inserts removed;
  • FIG. 4 is a sectional View taken at 4-4 of FIG. 3;
  • FIG. 5 is a sectional view of a railroad journal box containing a lubricator of the present invention
  • FG. 6 is an enlarged sectional View taken at 6 6 of FIG. 5;
  • FIG. 7 is an end view of a modified lubricator
  • FIG. 8 is a view similar to FIG. l but showing modifications
  • FIG. 8A is a View showing a modified form of pullstrap
  • FIG. 9 is a view similar to FIG. 5 but showing a modified form of lubricator in the journal box.
  • FIG. 2 of the drawings One form of the present invention is illustrated in FIG. 2 of the drawings as embodied in a lubricator 10 which, as shown in FIGS. 5 and 6, is to be removably mounted in the journal box JB of ⁇ a railroad Vcar in position between the lower periphery of the car journal and the bottom wall 12 of the journal box.
  • the construction shown in FIGS. 5 and 6, insofar as the journal box is concerned, represents standard AAR construction, and it will be noted that the journal I engages a conventional segmental bearing B which is held in position ⁇ at the top of the box by a conventional wedge W.
  • the bottom wall 12 of the journal box being spaced well fbelow the journal I, affords ay reservoir for lubricating oil L, and the lubricator 10 being positioned therein will relay large quantities of the lubricating oil onto the journal J which in tlligrn will carry oil to the lining BL, FIG. 6, of the bearing
  • the lubricator 10 in the present instance is a two-pad construction and includes a pair of block shaped inserts 14 and 15 of identical construction, dimension and configuration so that the blocks 14 and 15 are interchangeable and reversible.
  • Each of the blocks 14 and i5 consists of porous, resilient, oil resistant material such as foam neoprene or the like.
  • the pore openings are of materially reduced dimension in comparison to the enlarged openings 17, so that when the blocks are placed under compression due to up and down movements of the journal J compressing the lubricator 1Q, oil trapped within the openings 17 which open at the bottom of the blocks 14 and 15 adjacent the bottom wall 12 of the journal box is placed under compression.
  • the trapped oil so compressed is forced upwardly through the porous body area of the inserts to emit as jet Sprays from the upper faces thereof, and this accounts for an increased pressurized relay of oil to the fabric casing surrounding the blocks 14 and 15.
  • the ordinary manner of lubrication in the present instance is by capillarity, but under the circumstance described immediately above there will actually be pressure lubrication achieved without any mechanical parts.
  • the blocks 14 and 15 are rectangular on all sides and are to be arranged within respective confining pockets afforded by a pair of closed loop sleeves 1S and 19, FIG. 1, and these sleeves are for-med from a fabric casing of wicking material so that the lubricant absorbed in the blocks 14 and 1S will soak by transfer capillarity into the sleeves in which the blocks 14 and 1S are confined. Additionally, the fabric casing is provided with a pile surface as will be explained.
  • the porous blocks 14 and 15 are surrounded on their upper and lower faces and their side faces by a fabric casing 2i? of light weight cotton duck material or the like.
  • This casing 2d is constructed from two like pieces of duck material 20A and 20B, FIG. l, initially of rectangular form.
  • Each wicking piece 20A and ZLB, in constructing the lubricator, is folded in bight form with the free ends 20E lapped one over the other at what will constitute the remote longitudinal outer sides of the casing.
  • the end flaps thus afforded are preferably encased yin looped pieces of heavy duck 25 folded in U-form and telescoped over the lapped ends 20E of the fabric casing 2Q at the two outer sides.
  • stiffeners 25 In securing the stiffeners 25 in place, this is preferably accomplished by stitching as indicated at 27 in FIG. 2, but when it is expected that less severe circumstances will be encountered in the field, staples can be used. It will be recognized that heavy canvas duck is chosen for the stiffeners 25 primarily because of availability, low cost and ease in stitching. These serve as limit stops as will be explained, and also confine the pile loops present on the end flaps 20E, and hence numerous equivalents can be relied upon.
  • the foregoing open-ended sleeve construction affords elongated pockets as shown in FIG. 1 when the sleeves 13 and 19 afforded bythe fabric pieces 20A and 211B are opened.
  • the sleeves are so dimensioned as to easily receive the porous block inserts 14 and 15, and of course the sleeves have opposed substantially parallel top and bottom sides corresponding in length and width to the top and bottom faces of the blocks 14 and 15,
  • narrow webs 311 of light-weight duck are secured to the open ends of the casing sleeves being stitched at the upper and lower ends thereof to the inside surfaces of the upper ⁇ and lower faces of the sleeves in which the inserts 14 and 15 are disposed.
  • Such stitching of the retainer webs 30 is of course completed once the inserts 14 and 15 have been arranged in place, at least in respect to the webs 30 at the open ends of the sleeves into which the inserts 14 and 15 are rst passed.
  • the adjacent inner sides of the sleeves are to be joined along Ia restricted longitudinal medial line to thereby ilexibly join the two sleeves to allow for ready conformability of the lubricator to the dimensions of the journal as shown in FIG. 6.
  • This joining is accomplished by stitching together the adjacent inner sides of the two sleeves as indicated at 35 in FGS. 3 and 4.
  • brass grommets 36 are crimped in place at the fore and aft ends of the inner sides of the sleeves as shown in FIGS. 2 and 4.
  • these grornmets constitute hook receiving elements whereby a substantial force can be applied to the lubricator by a conventional packing hook incidental to positioning the lubricator within the journal box or withdrawing the same from the journal box. By so resorting to metallic grommets, there is little likelihood that the packing hook will produce tearing or distortion of the fabric casing.
  • V-channels 4t? and 41 are produced between the adjacent inner sides of the sleeves respectively above kand below the securement as 35 which joins the two sleeves at their adjacent inner sides.
  • the ⁇ /channels 4l) and 41 are filled with an auxiliary or filler wick 43, FIGS. 1, 2 and 3.
  • This filler wick is of light weight duck wicking material, and in the form of the invention shown in FIGS. l, 2 and 3, is separately constructed.
  • the filler wick 43 is made from la single piece of cotton duck wicking material which is so folded as to have the free ends 43E, FIG. l, lapped one over the other.
  • This filler wick is arranged between the adjacent inner sides of the sleeves before the latter are joined by the stitching 35.
  • the iiller wick is stitched in place as an incident to the joining of the two sleeves, and preferably the lapped ends 43E of the filler wick are stitched together asa preliminary step.
  • the resultant construction is one wherein the filler wick affords an upper loose closed loop 43U disposed in the upwardly opening V channel 40, and a like loose closed loop 43L disposed in the lower or downwardly opening V-channel 41.
  • the lower loop 431. of the filler wick will be located at the longitudinal center line of the bottom wall of the journal box where the oil will be at its greatest depth.
  • the upper loop 43U ofthe auxiliary filler wick will fill the void of the upper V-channel y40 in the area between the sleeves on the vertical center line of the journal.
  • the fabric sleeves composing the fabric casing 26 are separately woven with cotton loops delinin'g an exceedingly thick and iluffy pile surface on exposed surfaces of the sleeves.
  • This pile surface is afforded lby conventional chenille weaving simply by looping the chenilling threads back ⁇ and forth so that the chenille loops 50 are relatively taut within the fabric casing or cover 20 with the outer or exposed loops 51, FIG. 3, in ⁇ an elongated loose state.
  • the lubricator will tend to pick up to some extent the motion of the journal when the latter is rotating, and hence move slightly toward one side or the other of the journal box depending on the direction of rotation of the journal.
  • the stiifened or reinforced end flaps at the two outer sides of the ⁇ lubricator will engage one or the other waste retainer lug WL or stop column SC, FIG. 6, of the journal box thereby limiting the extent of lateral shift of the lubricator yand preventing any entrapment thereof between the journal and the bearing B.
  • stiffeners or retainers 2S effectively shroud the loop piles that are present on the end iiaps 20E of the fabric sleeves, and it has been found that particularly in cold weather such shrouding prevents the loose chenille loops atr the end iiaps from being drawn upwardly or downwardly by the journal.
  • FIG. 7 A modification of the present linvention is illustrated in FIG. 7 having to do with a modified -forrn of fabric casing 20A which affords the sleeves.
  • the filler wick is constructed from the fabric casing, and the stiifening of the outer sides of the fabric casing to afford the retainers mentioned ⁇ above -is omitted.
  • yas shown in FIG. 7 a pair of individual ⁇ fabric pieces of rectangular shape, similar to those described above and ⁇ dimensioned in the same manner and embodying chenille loop threads, are folded so ⁇ as -to have the -free ends 60E and 61E thereof lapped.
  • the respective textile wick sheets affording the sleeves shown in FIG. 7 are folded 4and tucked in an identical manner to complete the related sleeve and one half of the -wick filler.
  • this is folded downwardly from the lower end flap 60E to afford one hal-f of an outer side 64, inwardly to afford a bottom side 65, and upwardly to afford an inner side 66.
  • the inner side at the top thereof is folded back on itself at 67 and extended downwardly at 68 in parallel relation to the side L66.
  • the second ply inner side 68 is directed downwardly beyond the plane of the lower side 65 and is looped back on itself at 69 to afford the lower half of the filler loop and still a third inner side ply 70 is then turned at right angles to afford the top side 71 which extends across the top lof the lubn'cator in parallel relation above the bottom side 65, and then is turned ⁇ down at 74 and out to the upper end flap 60E to ⁇ complete the outer side of the sleeve 60.
  • the right hand sleeve 61 can be viewed as an inverted mirror image of :the left hand sleeve 60 described above, having a filler wick loop 69K which represents the upper loop of the lil-ler wick.
  • the resultant six-ply center section at the inside of the casing 20A is ⁇ stitched together at 75 along a restricted medial longitudinal portion in the manner ⁇ described above 4for the casing 20, and grommets as 36 can be applied at 4the fore ⁇ and aft ends ⁇ of the sti-tch 75.
  • a lubricator having the casing 20A will have the outward appearance of the lubricator 10, FIG. 2, and when positioned in a journal box, the filler wick loops ⁇ 69 and 69R will respectively occupy the positions of the filler wick loops 43L and 43U, FIG. 6.
  • FIGS. l8, 8A and 9 Further modified forms of construction are illustrated in FIGS. l8, 8A and 9, and referring to FIG. 8 the construction illustrated by this figure is identi-cal to what has been described ⁇ above in connection with FIG. l,
  • center filler wick designated 43A in FIG. 8, -is of greater longitudinal dimension Ithan the sleeves 18 and ⁇ 19, and the ygrommets 36, FIG. 2 have been eliminated.
  • the center ller wick 43A has free edges 43AE that are abutted rather than lapped, and a strap y is laid over the abutted edges of the wick 43A and is stitched at SGS parallel to the abutted edges of the wick 43A to firmly secure the strap 80 to ⁇ the center wick insert.
  • the strap 80 is of substantially greater longitudinal dimension than the center wick 43A, and the free ends of the strap 80 are turned back on themselves to alford end loops 81 and 82. The free ends of the loops are stitched at ⁇ 81S ⁇ and 82S to the Iinner portions of the ⁇ strap inwardly of the lloops 81 and 82.
  • the loops 8l and 82 constitute handles or hook receiving elements freely available at the front and rear of the lubricator as shown in yFIG. 9, which illustrates the lubricator constructed in accordance with FG. 8 as mounted in position within a railroad journal box. It will also be noted in FIG. 9 that as a result of imparting greater longitudinal dimension to the wick 43A in comparison to the center wick 43 of FIG. l, the end portions E1 and E2 of the center wick insert or filler 43A will wipe the fillet surfaces F1 and F2 of the car journal respectively at the collar and dust guard seat portions of the car journal.
  • the sleeves of the lubricator of the present invention normally are of less longitudinal dimension than the distance separating such fillet surfaces of a standard car journal so that the major portions of the sleeves are ⁇ free of these fillet surfaces, Abut by lengthening the center filler wick the ends ofthis wick will embrace the fillet surfaces F1 and 'F2 and transfer copious amounts of lubricant thereto.
  • a modified form of the strap shown in FIG. 8 is illustrated at 30A in PIG. 8A.
  • the construction is substantially the same asvthat illustrated at Si) in FG. 8,
  • grommets 85 and 86 are fastened to the loops -81 and In each instance, however, the use of the strap S0 enables the entire pull to be absorbed or borne by the strap during removal of the lubricator from the journal box or positioning thereof in the journal box.
  • the use of the grommets 8S and S6 in addition to the stitching greatly increases the pull limit, and in any event the stitching discourages unraveling.
  • porous pad inserts of rectangular dimension such dimensioning can be varied, and of course inserts of various forms and kinds can be used. Under proper circumstances, the porous pad inserts could be altogether eliminated and resort had to other means for urging and holding the wicking sleeves and the center wick against the car journal.
  • two fabric sleeves of wicking material closed on four sides and open at both ends (except for the retainer elements as 3G) are flexibly joined at the inner sides along a restricted -medial portion only and are adapted to be filled with porous insert members capable of absorbing large amounts of oil.
