SPECFICATION forming part of Letters Patent No. 397,901, dated February 19, 1889, Application filed June 6, 1888. Serial No.`276,248. (No model.)

To all whom t may concern:

Be it known that I, WILLIAM Oris D UNBAR, a citizen of the United States, and a resident of Altoona, county of Blair, and State of Pennsylvania, have invented certain new and useful Improvements in Mechanism for Effecting the Lubrication of Journals and Journal- Bearings, of which the following is a specification.

In an application for Letters Patent filed by me in the United States Patent Office on or about October 26, 1887, Serial No. 253,434, and patented November 13,1888, No. 392,593, l have shown. and described means for effecting' the lubrication of the journals and j ournal-bearings of the axles of ears, in which a ring mounted upon the journal, or upon a stud projecting from its end, is caused by its rotation to raise the lubricant from the bottom of the box in which the journal-bearing is arranged and deposit it upon the ljournal itself, or upon a flange secured either to its end or to the stud, the distribution of the lubricant thus raised along the journal being afterward effected by means of projections and shelves or troughs upon the journalbearing, the former of which serves to remove it from the surface where deposited and to carry it tothe latter, which in turn conducts 'it to the journal and deposits it along the same. ll'ilh these devices are also employed a horizontal partition, which is arranged across the box containing the jou rnal-bearin g, near the bot.- tom thereof, to prevent the spilling or wasting of the lubricant as the box is thrown violently from side to side by the action of' the car when in motion.

My present invention, while applicable in part to journals and journal-bearings generally, is designed more especially for use in connection with the forms shown in the application aforesaid, upon which it is intended as an improvement, and has for its object not only the increasing of the efficiency of the saine, but also the simpli fieat-ion of some of the parts thereof.

To this end Ait consists, first, in a journalbcaring'which is not only provided with the parts for removing the lubricant 'f rom the surface upon which it is deposited and the shelves or troughs by means of which it is distributed along the journal, but also with supplementary shelves or troughs, whereby the more positive delivery of the lubricant from the former to the latter is insured than was possible-with the devices heretofore in use second, in the box in which the journal-bearing is arranged with its lubricant-holding receptacle and inwardly-projecting flanges or deflectors for preventing the spilling of the oil when such boX is moved violently back and forth, as is frequently done when the car is in rapid motion, and, third, in various other constructions and combinations of parts, all as will hereinafter more fully appear.

Referring to the accompanying drawings, in lwhich my invention is illustrated, Figure 1 is a sectional elevation of a j ournal-bearing, a box in which such journal-bearing is arranged, and the lubricating-ring, taken longitudinally of the journal, which is also shown. in elevation; Fig. 2, a sect-ion thereof taken in the line .r of Fig. 1; Fig. 3, a sectional elevation of the journal-bearing detached; Figs. 4l and 5, end and plan views, respectively, of the same, also detached, the former showing, in addition, the end of the journal in dotted lines; Fig. 6, a sectional elevationv of a journal-bearing, a box in which it is arranged, a lulnicating-ring, and a splash-guard of a slightly-modified construction, taken longitudinally of' the journ al,which is also shown in elevation; Fig. 7, a front elevation of the splash-guard to prevent the escape of the lubricant from the box thrown upward by the ring when in rapid rotation; Fig. 8, a side elevation of a slightly-modified form of journal-bearing and journal, with a stop for the end of the shaft shown in section; Fig. f), an end elevation thereof' with the stop partly in section, and Fig. 1() a plan view of the journal-bearing shown in these two last figures detached. f

ln all the iigureslike letters are employed to designate corresponding parts.

A indicates a journal, which is or may be provided at or near its end with a reduced portion, c, for reception of the lubricatingring B, which is mounted thereon; and a', a flange which maybe secured to or formed on such journal adjacent to the reduced portion thereof, if preferred. The reduced portion d may be formed either integral with the journalor in the forni of an independent stud se- TCO 5 application mentioned, reduire no l'urther deseription herein.

C indieates the journi'il-bearing,wliieh may be made in any approved t'orm, and is provided upon its lroiit end with projeetionse` c,

lriiijeetii'ig outward l'rom the lower edges ol' the journi'iil-bearing are the shelves e e', whieh extend the entire length thereof, and are preferably ot a gradui'iilly-diminishing zo width troni lront to rear, the sante being provided on their upper sides with grooves, il' desired,whereby to een vert theni into troughs.

The Vunder sides ol these shelves ineline in.- y ward and dowiiward. lroni their outer edges f and plaeed horizontally.

3o arrangement l prefer in praetiee, however, as the tran'smiss'ioiii ol' the lubricant tfroni the point where dej'iosited by the lub riea-tin g-ring along the length otthe journal is niore positive and eei-t'aiinaiid the inelinedlower edges 'ould to a large extent, if not entirely, nialze it possible to do away with the shelves along the lower edges ot' said bearing, it desired. lroj eet ing outward l'ro'in the outer sid es ol' the proj eetiions r; w, and extenifling lroin points near 4o their upper outer Corners in an inelined downwardv `direetion, are supplenientary shelyes el e2, the lower ends ot' whieh extend baekA and over the outer ends ot the shelves e e', the objeet and purpose oli whieh are to more positively insure the earrying baek and delivery to said latter shelves o tf the lubrieant thrown upon the sides olf the projeetious by the aetion of the (lange or other surl'aee with whieh they engage lwhen in rapid rotation,

l) indieates the liox in whieh 'the journalbearing is arranged, the l'orinerbeingprovided Vwith `the opening (i and eover tl', and the latter being supported in said liox in any wellknown manner-as, For inslanee, by a suitable bolster, d, toriiied upon its upper side, resting within an ap] iropriately-sliaped reeess, d', formed in the under side of its top or otherwise, as nia-y be desired. 'lhis box, in order to provide l'or the use ot' a more shallow eon- (io strut-tion than has been possible lieretofi'ire, is preferably provided in its bottom near its l'ront with a ehauiber or well, d?, for the reception ot' the lubrieant whieh is placed therein, and also for the lubrieatiiig-ring l,whieh dependsironi the redueed portieri (i ol' the journal, as shown.

Projeeting inward l'roni the baek of the box beneath the journal, and extendingI entirely aeross troni one side to the other, is a flange or detleetor, E, for preventing the lubrieant Yt'roni spilling through the oriliee between tlie journaland the box when the latter is thrown violently outward by the motion ol' the ear; and in order to prevent a siniilar spilling when the ear is thrown iu the other direetion l provide the inner side olf the t'ro'nt of. the box immediately below the oriliee (i therein with an inwardly-projeeting l'lange or del'leetor, 'l These [langes or detleet'ors E and l? are preferably inelined downward on join the box to their innerorlree ends, to aid in returningtlie lubrieant that maybe thrown upon tlii'iniibiiek. into the reservoir, and the detleetorli at thebaek of lthe box, iii addition, is made to partially surrouiid the jourlial, as shown, to allow more roombetween itsunder side and the bottom ot' the box for the lubrieantto expand into without seaping over its top as it is shaken about than is possible when sueli flange or del'leetoil is made straight Depending from the under side ol the top of the box innnediately in the rear of the i edge oli the opening (lr is a [lange orsplash- This last guard, ll, by means oli' whieh the lubrieant thrown against the top ol the box by the lubricating-ring when in rapid rotation is prevented from eseapiiig through said opening; and in order to insure more l'ullythe prevention of this waste the under side ol' the top of the box frein the llange ll inclined downward to the edge of the recess d', which reeeiv s the bolster d on the top of the journalbearing, as shown at ll, whereby any lubrieant striking the saine is eaused to :[low down this inclined surli'aee and upon tliebearing overwhieh it passes and is returned to the journal.

The flangesl or diiilleetors .E and l 1 will pret'- erably be made integrally with the boxv l), as shown in liigs. l a-nd L), butthe splash-guard lI niay be niade either integrally therewith, as shown in the t'oriner ol.' said figures, or detaehable therefrom, as illustrated Vin l `igs. and 7.

In the nianut'aeture ol' new boxes it nia \j' be eonvenient to make the splash-giutrd integrally, as is the ease with the flanges or delleetors mlll and .li, sinee the union ot' the various parts eau be readily elleeted lin the easting` ojiziiri'itiou, but iii the ease ol' oldboxes whieh are not provided Awith this deviee, and when sueh would be desirable, it will be neeessary to make it separate and afterward seeure it in plaee.

The flange or spliish-guard ll, when iliade detaehable, is preferably li'oriiied from sheet metal, and Consists ot' the strip 71 which is slightlylongerthan the distanee between the inner sides oi' the waills of the box in whieh it is to be used, and when in plaee will. rest upon the upper side of the 'projections e e ot' the journal-bearing (l, so as to suljistantially IOO TIO

cover the space between them, when one is provided, with its ends engaging with the inner sides of the walls of the box, a flange or portion, 7L', slightly narrower than the opening' G, being secured to the edge of the strip h at right angles thereto, so that when adj usted in place it will depend from the latter between the end of the journal A and the opening G. This flange or splash-guard may be made either of two pieces or one, as dC sired. I prcli'er, however, to make it of one, as the cost ot' manufacture is thereby greatly cheapened and a more effective ai ticle is produced.

In Figs. il, 2, il, 4;, and I have shown the supplementary shelves c2 applied to a bearing having two projections, c c, upon its end, the material between them being removed in order to lighteii the bearing as much as isv possible; but in Figs. 8, 9, and 10 I have illustrated them applied to a bearing' in which the two. projections are not separated, but appear as one, and a stop,K, for the end of the journal is employed therewith. lVith this construction I may sometimes find it convenient to provide means for preventing the proj cction c from 'interfering with the rotation ot lthe ring, as would be the case when the wearing' of the bcarin g has become so great as to bring it into contact therewith, and for this purpose I form an orifice, either by drilling or otherwise,through the projection above the ring,as shown at la, so that when the portionsof the bearing immediately above the journal and the liange at its end, when one is used, have been worn away sufficiently to bring t-he portion of the projection above the ring into contact with it such iformerportions will communicate with the orifice and allow the part below it to vfall out, and be thus removed `from possible contact with said ring. This orifice, as will be apparent, may also be used in connection with the f'orm of bearing employing' two projections upon it and for a like purpose, such bearings differing' from those employing' but a single projection only in having the space between the projections removed fer the purpose of lighteningthe same.

By the construction and arrangement of parts above set forth it will be seen thatI produce a jourmd-bcaring and abox therefor in which not only is the lubrication of the journal more effectively accomplished than has been possible heretofore, but the wasting of such lubricant by spilling is in a great measure obviated.

Having' thus described my in venlion and the best means contemplatml by me for carrying it into effect, what I cla-im as new, and desire to secure by VLetters Patent of the United States, is-
