which has adjacentto the Jrojeetionl a 1 perforated,enlargement or oss 19. Connected with the outer surface of` lug 17:is

a similar apertured enlargement 20. Above' the plate portion 15 and in alinement with the boss 19 web 10 also has an enlargement 21, :s

the same havin a centrally disposed aperture or hole in a inexnent with and forming a continuation of .the hole in boss 19. The end ortion of the side frame also has an en'- argement 22Yhaving a central hole forming a -fll continuation ofthe aperture or boss 29;..- l

vThe journal Abon or oil casing-Which' is adaptedv tobc fastened to and coperate with the end portion of the side frame shownin Fig. 1 is illustrated. in perspective.,inFigi'2 EL and .comprises a` receptacle -23 .having ver'ti# cal Aside walls 2li-and 25 arid arounded bot.-v tolnv 26, its top wall -Zbeing 1 lat as indicated andx supplied with longitudinal rectangular .apertures Orholes 2S extended?therethrough il and located just inside of the walls 24 and1252- These apertures 2S are oil-substantially the same .dimensions as the projections or lugs 16- and 17 which are adapted to pass throughy the the box. The side walls -and 25 'Of'the casing .haveA at"'their top` central portionsl sane and vproject intothe interior portion-ol connecting,r with thel apertures 28 and wiitliv "i" the interior of the box, as is clearlyshowii'; The bottomwall of each of these enlarg'l ments which is horizontal is centrally aper-A tured at 31, andthe innerI enlargement 29 hasf a vertical 'slot32 of substantially the same' width as the thickness Of web 18 and adapted to accommodate the saine when the journal box is in position on the. side frame.

When thc two parts are attached togcth'er i the to wall -27 vol the box or Casin(r lies rectly eneath tiie plate portion 15 Olathe side Y frame, projectioi'is 16 and 17 extend throufhv the rectangular holes or apertures 28 into t ie box, the bosses 19 and 2() are neatly housed within'the enlargements 29 and 30, land the"4 I 'I slot 32' accommodates the web 1S'as mention-' edabove.' l`o`hold thc box in this position and securely maintain it in place l use a U- shaped bolt 33, the arallel legs of which pass I through the vertica holes in the bosses 19, 20

box, or only the bottom alone, may have a; rounded groove 35 to receive and acc'or'nmo date the bolt 33. To prevent a weakening of the box at this point its thickness may be somewhat increased and the-thickened or tion grooved. Box 23 onV the under si e of its top wall 27 has the usual downwardly projecting lugs or ngersv 36 adapted'to' engage and cooperate Awith the outer end of the wedge 37, the in .ner end of which is overlapped by a flange 38 on the journal bearin 39, whichhas on its sides laterally extende shoulders 40 overlapping and co-aeting with the outer faces of projections 16 and 17. As

is usual, the end of the axle upon which the bearing rests is somewhat reduced in diameter, thereby providing the inner and outer shoulders 41 and 42 which may engage the ends of the bearing as the axle tends to shift lengthwise in one direction or the other. The shoulders 40` coperating `with the projections 16 and 17 revent inward movement of the bearing an axle,-outward movement of the same parts, as well asimilar movement of the wedge, being prevented by the ingers36.V e v Y t has been found from experience that wh'emthe rojections corresponding to the lugs 16 and) 17..are.cast integral withv and on the inside oi the journal box they are likely to .become broken or injured, due to the shocks to Whichvthey aresubjected. By

forming the rojections or lugs 16 and 17 integral with t e side frame and making them and the strains are transmitted directly tov of cast steel as are the side frames they Withstand the shocks much more vsatisfactorily the side frame rather than indirectly through the journal box, as has heretofore been customary. Another advantage of this forni of side frame and journal 'box casing is that the latter ma be readily andV ickly separated ame Without diiliculty by merelIv removing the nuts 34 from the U-sha ed bo t 33. In order to exclude dirt and ot ier foreign substances from the interior of the box, the joints between the same and the side franiemay be acked with any suitable material, asis wel understood. It should be noted furthermore that the enlargements 19 and 20 not onl aord means for the accommodation of t e U bolt but also materially aid in bracing the projections 16 and 17 and holdingthem in lace.

To those. skil ed lin the art it will be -apparent that many minor mechanical changes may be made in the structures shown and described without departure from my invention.
