Said tension and kcompression members 1 6 .and 17 ,are connected together at the corresponding ,end portion 1 8 of the side frame,

which end portion 18, in ,the illustrated embodiment .of the present invention, has formed box 19.

Though an integral journalbox is illus,- trated inthe drawings, AitWill be clear as the vdescription proceeds that many features of integre-lV therewith the l)journal j the vinvention are not limited to l integral tremitvof the jourrlel boze 'es `ind.oe.it;eol by vShadingill Figure *By 'reason' of the bevelled eonstrfifi ctiony referred to, not only are ,Sharp Cornersl avoided end the emooilt of metal reduced,l but `iurthe rrnore the beam action over the journal, boris Shorteneel Yenel a more yrigid andstronger design with -more uniform vsection,of metal is provided.

course, the saving of metal.

In order to explain the advantages of the present invention relative to the lowering of the point of intersections of the neutral axes of the tension and compression members V16 and 17, reference is made to Figures 11V, 12 and 13, which show cross sec-V provided with the outturned flanges 23.

The neutral axes of the tension member 16 andthe compression member y17 arcindicated by the lines 2a and 25, respectively. Bly reason of the described cross sec-tional i shapes of said compression and tension ,direct action possible.

members, and by reason of thevbevelled construction at the upper inside corner of the journal box, said neutral axes 2-1 and25V are brought to a point of intersection substantially in the vertical central plane of the journal'box 19 at a relatively low level. Y

AsVA will be noted'from an inspection of Figures 1 and 5, the web of the channel comprising the tension member 1.6 is in substantial alignment with the adjacent bevelled portion 19 of the roof of the corre,- sponding journal box, whereby the metal of tension member 16 is Vwell adapted to transmit the stresses. Saidweb of the tension member 16,7it ywill be noted, slopes substantially from the inner sides of the wedge or Vbrass lugs,1919V between the flanges ofV Y the corresponding compression andV tension members. By reason of the coordination of the journal box having bevelled edges re"- ferred to and the'tension and compression members as described, the necessary Vheight ofthe frame is reduced, and at the Ysame `time the metalof the journal box isv located in line with theV forces, producing thezmost the journal box is thereforeminimized, accomplishing improved sturdiness over prior practice, withI a' reduction in metal and a reduction ofY tendency tocrack. The angular yarrangement betweenjthe roof of each rjournal box'and the inner side wall thereof outwardly of the tensionv member is such that'the roof ofthe journal box meets said inner.V side Ywall at substantially right angles. lntermed'ate ofthe iiangeseof the tension member, however, fthe .angular arrangement above referred to is maintained and this extends back to the usual dust guard well The same arrangement is followed atthe outer corner of the roof or outer sidewall of the Beam action over Y box, so that the journal box cores for the right and left sidesV thereof may be made similar.

The junction of the tension member 16 to the journal box 19 is reinforced by the web 26 and by the laterally extending *strengthening ribs of webs 26a. The web 26 has a strengthening -rib or web at its lower edge, as indicated by thenumeral/26b. Said rib 26b4 has considerable width at its central porprovided in alignment with the innerk wall of the tension member 16. Said webs 29-29, Y

together with said inner wall of thetension member 16, extend from the lower edge of the bolster opening 30 to the top of the compression member. This structure isbeneiicial in VtransferringV stresses, and also prevents excessive buckling. 1n the-constructionshown in Figurev 7, the webs 26, 26a, and 26b have been eliminated.V i

Figures 9 and 10 illustrate a construction in which a rib or web 31 is provided extending` from the inner wall of the compression member 17 to the journal box 19.- Said rib or web is of material benefit in strengthening the side; fra-me, prevents excessive buck-Y p Ving sense. Many modifications will occur to those skilled in the art. 1t is intended to cover all such-modifications that fall with'- j inthe SCOP@ 0f Ghoappended c'laimsl f` What is claimed`is- A 1. A" sideframe comprising a bolster receiving portion, a compression member conf nected, to theupper part of said bolster receiving'portion, a tension member connected to the lower `part of said bolster receivingV portion, said tensionV andcompression members being disposed in angular relationshipY with each other' 'and being connected together at their vouter ends, a journal box joined to said'tension and compression members adjacent to the pointof junction ofsaid members, said tension and compression members comprising channel sections having their neutral axes disposed at a relatively low level, which neutral axes intersect substantially at the vertical central plane of said journal box, said journal box and tension member being provided with a reinforcing web therebetween, the lower` portion of said web being provided with a rib of greater width at its mid portion than at its end portions.

2. A side frame having a compressionV member, a tension member, a journal box integral with said tension and compression members, said tension member comprising a channel section having its web lowermost, said journal box and tension member being provided with a reinforcing web therebetween, the lower portionraof said web being provided with a rib of greater Width at its mid portion than at its end portions.

3. A side frame comprising a compression member, a tension member and a journal box integraltherewith, said journal box and tension member being provided with a reinforcing web therebetween, the lower portion of said webbeing provided with a rib of greater width at its mid portion than at its end portions. l
