Hennessy, New York, N. Y. Application February 19, 1934, Serial No. 711,933 12 Claims. This invention relates to means for recover ing excess lubricant supplied to journals, and particularly railway locomotive driving journals, much of which lubricant Would otherwise escape endwise of the journal and be centrifugally thrown off outside the journal box and lost. In order to insure satisfactory lubrication of (Cl. 308—80) which may be easily replaced when Worn or dam aged. ' - ' - These objects and others are attained substan tially by the structure illustrated in the accom panying drawings in which—- a Figure 1 is a vertical section through a loco motive driving box lubricator assembly and taken railway vehicle journals which support heavy substantially along the axis of the journal. loads, it is desirable to supply ample quantities Oil in su?icient quantities may be supplied to the bear ing from above the journal by means of conduits 10 of lubricant to the journal at all times. leading through the crown bearing or from a res ervoir carried in the lower part of the journal box 15 by means of a suitable pumping device such as that illustrated in co-pending application Serial No. 558,719, ?led April 22, 1931 in the name of the present inventor. Where the lubricant is pumped from a reser 20 voir within the box itself, the pump may be ad justed to constantly maintain a pool of oil at the surface of the journal providing so-called bath lubrication. ' However, much of the oil supplied to‘the jour 25 nal in such quantities is squeezed endwise beyond the bearing brass and, in the absence of suitable recapturing means, is thrownoff and lost. The oil recapturing devices heretofore in use gener ally have not been ef?cient enough to prevent ex 30 cessive oil losses where lubricant is constantly supplied to the journal by gravity or where bath lubrication is provided and, accordingly, such lubrication, though desirable from a mechanical standpoint, has not been considered practical. It therefore becomes necessary to provide bet ter means for recapturing lubricant than have heretofore been devised in order to permit the furnishing of relatively large quantities of oil to railway journals without substantial waste. 40 Moreover, with the use of e?icient oil recapturing means a relatively simple inexpensive pump may be provided, or oil may be supplied conveniently and simply to the bearing by gravity from an overhead reservoir. The main object of the present invention is to provide e?icient means for recapturing oil escap ing beyond the ends of the bearings‘ of railway vehicle lubricated journals. A more detailed object is to provide novel 50 means for recovering oil thrown off from the journal outside the journal box cellar and re turning the same to‘ a cellar within. the box. Another object is to provide an oil wiper for vehicle journals which may readily adjust itself to the position and contour of the journal and Figure 2 is an end View of the assembly, por tions being broken away and shown in section '10 substantially on the linev 2-—2 of Figure 1. Figure 3 is a perspective View of one of the wiping devices, a portion being broken‘ away. _ Figure 4 is a transverse section through the £115 center of the structure in Figure 3. : Figure 5 is a longitudinal section through a device somewhat similar to that in Figures 3 and 4 but modi?ed as to a detail. Figure 6 is a top view of another form of jour nal wipen' ' ' I 1 Figure 7 is an end View of the device in Figure 6. Figure 8 is a side view of the same. ‘ In Figures 1 and 2 of the drawings, the inven tion is shown applied to a locomotive driving box having the usual heavy side walls i for engage "25 ment with'the underfran'le pedestal (not shown) and receiving the crown bearing brass 2, the ends of which are undercut as at 3. Located in the ‘lower portion of the driving box is a lubricant cellar 4 which is downwardly enlarged in its inner $30 portion to form a lubricant reservoir‘ 5. VWithin this reservoir is the body portion 6 of a lubricant pump which is actuated by the contact rod 1 extending through a tubular housing 8 within the cellar and engaging, the hub 9 of the adja—*135 cent driver. It will be understood that lateral play of the driver and journal relative to the driving box will cause lubricant in reservoir 5 to be pumped through the screen l0, body‘ 6, tubular housing 8,;transverse passage i I, and upright de 40 liveryrmember I 2 to the cup l3 where, during operation of the pump, a pool of oil is maintained in contact with or adjacent to the surface of the journal. Ball checks I4 and i5 are provided to145 trap the lubricant in cup l3. ‘ V - Maintained adjacent the journal by means of a spring 16 is a lubricant distributing device shown in'the present instance ‘as formed of a series of strips ll of suitable absorbent'material .»5_0 such as felt or celotex and intervening spacer vstrips I8 which may be of wood. At the. ends . of the lubricant cellar are ba?le plates 19 and 29 for preventing the splashing out of lubricant overv the top edges of the cellar end walls_;2ll and 255 2,107,413 2 22 which are slightly spaced from the journal as shown at 23 in Figure 2. The details of the driving box, pump, and oil distributor shown do not in themselves con stitute the present invention. The pump is more clearly described in the above-mentioned co pending application Serial No. 558,719. ' In order to prevent lubricant from escaping over the side walls 24 of the cellar, these walls 10 extend into grooves 25 formed in the side por tions I of the driving box immediately beneath the side edges of the bearingbrass 2. This feature is covered in co-pending application Serial No. 728,894 ?led June 4, 1934 by the pres 15 ent inventor. At the inner end of the box is provided a closure member 26 surrounding the journal and including a portion 28 forming a cover for the reservoir 5. Closure member 26 includes a felt strip 21 with its inner edge bent 20 over as at 29 and snugly engaging the journal to prevent the loss of lubricant through this por tion of the box. ; ' It has been observed that lubricant squeezed out from under the bearing tends to form in a 25 ring adjacent the end thereof and is centrifugally 535 thrown oil from the journal in the form of drops. In order to bring this oil ring within the end wall 22 of the cellar, the brass is undercut as at 3. However, due to the lateral play of the jour nal, some of the accumulated drops will be thrown outside the cellar wall. In order to re cover the oil thrown off the journal outside the cellar and which would be otherwise lost, a series of cooperating wiping and collecting devices A, B and C are provided for wiping the journal, and particularly the portion thereof outside the cellar outer wall 22, and'returning the recovered lu bricant to the cellar; ' The wiper A, Figures 3 and 4, comprises an elongated box-shaped housing 30, which extends through and is rigidly secured to ‘the end wall 22 of the lubricant cellar. The top wall of the housing is longitudinally slotted to receive the journal wiping rib 3|. The rib 3| is enlarged 45 in its lower portion’to form shoulders 32 for seating against the slotted top wall of the hous each side. At the inner end of the body por tion is a curved arm 44 arranged to seat against and extending partially around the surface of' the journal. This arm serves as a stabilizer for the wiper. ' . Seated in a hemispherical bearing 45 in the undersurface of the wiper body is a pin 46 (Fig ure 2) extending through aperforation in the splash plate 20 and urged upwardly by a coiled 10 spring 4'! seated against a washer 48 held against movement along the pin by means of a cotter key 49. A spacer bushing 50 surrounds the pin 46 and has slots 5| for accommodating the cotter 49. The wiper body is thus yieldingly and adjustably 15 maintained in contact with the journal. At the sides of the wiper B are upright bolts . 52 seated on the bottom of the cellar and ex tending through the splash plate 20 and ter minating in close proximity to the journal. 20 These bolts serve to relieve the wiper mechanism of excessive vertical loads in case the driving box is jacked up as for renewing the bearing brass. The wipers A are located closer to- the side 25 edges of the bearing than the wiper B and, ac cordingly, these need not extend quite as far beyond the end wall of the cellar as the latter in order to recover oil moved away from the end of the hearing by longitudinal play of the jour 30 nal. However, it is desirable that all of the wipers extend beyond the end of the endof the bearing. There will be a tendency of lubricant to travel longitudinally within the grooves 25 in the sides , of the driving box and in order to recover lu 35 bricant in these grooves which may travel beyond the end wall of the cellar, the angle-shaped cups C are provided which extend to the ends of the grooves. Each of these cups is formed of a metal strip bent in the formof an angle and its side v49 "edges buttwelded to the end wall of the cellar and underlying the end of the depending lip of the box groove 25. Collected lubricant is drained through the hole 53 in the cellar wall. The col lecting devices C are illustrated and claimed in 45 the above-mentioned co-pending application ing 30. At the bottom of the housing is a cup Serial No. 728,894. like depression 33 seating the spring pressed plunger 34 for urging the rib wiper 3| towards herein described, substantially all the lubricant 50 the journal. Preferably the ends of the en larged lower portion of the ribbed wiper are rounded as at 35 to facilitate insertion thereof past the plunger 34, this plunger in the as sembled device seating in a depression 36 to 55 yieldingly resist withdrawal of the wiper. Pref erably the rib 3| engages the journal along line inclined to the horizontal, as indicated in Fig ure 2, so that the recaptured lubricant will be drained along the upper surface of the rib into 60 is inclined downwardly from the center towards the cellar. > ' r ' In Figure 5 is shown a ribbedwiper device 31 mounted in housing 38 similar to that in Fig ures 3 and 4, but the wiper is urged towards the journal by means of a bent flat spring 39 nor mally seating in a depression 40 in the under surface of the wiper. In this as well as the pre ,vious formthe wiping rib is yieldingly and ad justably maintained in contact with the, journal. The wiping device B,.detailed inFigures 6, '7 and 8,. comprises a body portion’ including ribs W4I_with upper journal engaging surfaces inclined inwardly and downwardly. Lubricant recovered ,by ribs 4| is collected in inclined troughs 42 and ‘ the space between the ribs and drained by gravity to the transverse outlet trough 43 which With the use of the oil recovering devices escaping beyond the end of the bearing is re covered, only just enough being allowed to es cape to properly lubricate the hub face and box hub liner. Each of the wipers is yieldingly mounted on the end of the cellar and arranged to collect lubricant on the journal and return the same into the cellar by gravity. With the 50 use of these recovery devices bath lubrication of r the journal is made practical and also it is pos sible to supply oil to the journal by means of a 460 simple inexpensive gravity feed without the dan ger of excessive losses. Various details of the structures as illustrated and described are not essential and these may be modi?ed as will occur to those skilled in the art 165 and exclusive use of all such modi?cations as come within the scope of the appended claims is contemplated.
