cartr'uc'ks, and it aims to provide a cheap and simple improved construction therefor.

My invention contemplates, among other objects, theprovision of a. truclr side frame having the maximum strength for the minimum amount of metal; a wrought metal, as contradistingu'ished from a cast metal frame, ofthe gnr'aldianiond shape, having integiiafi yiftjrih dlop and bottom chords; an inte'gially'fofihed frame which may be readily formed wholly or partially from ,wrought metal eonventional hapes, such as the" commercial rolled steel shapes; and novel forms of bolster guide bars or columns.

As a wrought metal integral side frame, my invention will be found to present a construction particularly advantageous over 2 indicates the frame proper which prefer- Iably comprises a conventional rolled steel I-beam, the web 3 of which is intermediately 2' split or slotted and the flanged edges 4 and 3 5, and adjoining portions 3 and 3 of the- Web spread "inthe plane of the web to form the upper andlow'er chords 6 and? respec-j the cast frame type mentioned above. Cast frames have been found highly objectionableby i'ea sonof thegfact that the variations in shrinkageofthe metal alter or vary the distance betweenthc centers of the journal boxes which are usually .cast integrally with the framehor if not east therewith, are

carried by a frame mounting to alter which, v

to meet these variations, would weaken the frame and reduce its etficieney. Furthermore, as is Wellknown, great strength in cast strhctures is combined only with. enor mous weight, and coupled with, these objectionable features are the'liability of thecast metal to warp, and the necessity for discarding the whole frame should only a part thereof become injured.

My invention overcomes these difiiculties by the provision, as stated above, of a 'sim ple, light and strong construction, embodiments cfwhich are illustrated in the accompanying drawings inconnection with which I will now describe my invention so that others skilled in the art may understand and.

the line l4c of Fig. 2; Fig. 5 is a part ele-' vation showing modified manner of securing the bolster guide bars or columns to the frame proper; Fig. 6 is a transverse seetional view of the frame proper, being taken on a line substantially central oftliefi'aine' Fig. 7, is a detail-perspective view'of one of the members of the' bolster 'guide columns, Fig.8 is a similar; view iof theother member of the guide column; and Fig. 9 is a trans- .verse sectional View through the frame,

showing' modified manner of forming the f bolster guide columns and the spring plank seat.

In describing myinvention, the reference tively of the frame. gTo strengthen,"tlie frame generally and the chords 6 and-T particularly, I preferably provide the web '3 with the outwardly projecting.marginal flange 8.. In carrying out the'aboveI form-I ing operations, .the beam is preferab y first heated.

The flange 8, as shown, is somewhat Wider or more extended at the central portlon of the lower chord 7, as indicated by the numeralv 9, so as to form, in complement with the member 10 secured in opposite disposition thereto, a broad seat' for the spring plank 11 of the truck. The member 10 preferably comprises a section of commercial angle bar, v'vhich,.a's' shown, is disposedso as to bring a flange or leg portion 12' in alinin'g c0- l3 depending and in facial abutment with and secured, preferably by welding, to the web 3* of the lower chord.

While union bet-ween the web 3 and inem-,

. ber is preferably through welding, and

in this respect operates toward integral formation of the frame, an advantageous feature spoken of above, I do not desire to limit myself in this respect, as it will be apparent that rivets, as described below, or other suitable fastening means may be employed for this purpose.

The numeral 14 indicates the bolster guide bars or columns which are secured to the chords 6 and 7, and comprise preferably the angle plates or sections 15 and 16. The section 15 maybe a continuation of the horizontal angle section 10, being off-set as at 17 and 17 so as to cause its flange portion or leg 11 to lie substantially within the plane of the web 3 in preferably welded union with the similarly disposed. flange 19 of the member 16 which lies between the flange portions 8 of the chords 6 and 7 the terminal portions of the member 15 being secured, preferably by welding, to the inner i face of the webs 3 and 3 of the chords, while the member 16 carries the terminal flanges 20 which are secured preferably in a like manner to the flange portion 8. The other flanges 21 and 22 of the angle pieces 15 and 16 oppositely disposed, cooperate to form the guide faces for reception of the similarly faced end of the bolster.

, The columns 14 may flare or diverge at the base, as at 23, to permit of the endwise removal of the bolster, in the usual manner, and as the vertical travel of the bolster under service is, by reason of the usual undertmounted springs, spring seat, and plank, limited in a sense to the upper part of the columns, I preferably make the flanges 21 and 22, atthe base of the column, a width uniform with that of the wide springseat; the flanges narrowing to standard guide width at the top' of the columns, as is clearly shown. This construction not only conduces to symmetry but provides ample reinforcement for the outer edges of the flanges 9 and 12 which form the spring plank seat. The columns 14 in addition to their service as guides for the bolster, may also form struts for cooperative formation, with the upper or compression chord 6 and the lower or tension chord 7 of a truss construction. The strut or struts so formed are, by reason of their flanged construction, peculiarly adapted to maintain proper lateral stifiness under operative stresses. Furthermore, in the particular arrangement shown. there is absent all leverage or buckling strains between the chords and the struts, by reason of the fact that the united flanges 11 and 19 lie in a plane substantially in registration with that of the vertical member or Web of the frame and that consequently vertical 0g erative stresses passing between the chor s and struts are delivered in substantially coincidental lines.

In Figs. and (3 I show the angle sections 15 and 16 as being riveted together and secured in a like manner to the frame chords .6 and 7, as distinguished from the construction shown in Figs. 1, 2, 3 and 4, which views are to be understood as showing the several parts of the frame secured to one another by welding.

In Fig. 9 I show a modified manner of forming the spring plank seat. In this view the web of the frame '2 is shown as being formed without the flanges 8 and 9 at the center of the frame and as having an angle member 15 whichis substantially a duplicate of the meinber' lS and which is secured to the outer face of the frame or to the web of the chords in opposite disposition and in cooperative association with the said member 15.

It will be apparent that many. changes may be made in the construction shown,

which would not be a departure from myinvention, and I do not, therefore, desire to limit myself thereto.

The frame construction shown ma be readily adapted to any suitable journa box construction. In this-respect theend construction of the frame may be inthe general nature of the regular pedestal formation, a construction well known in the art, or the frame may be adapted to a particular form of box construction, such as indieated by 1the numeral 24 and which is claimed in a co-pending application of mine, Serial No. 574,343, since What I claim is:
