Application filed ,February 18,, 1925... -Seria1No.-l0;218.

The invention described herein relates to 1 .of wrought metal and ,integrallone with the other at their ends, and the strut forming the bolster columns formed of cast metal.

The inventionis hereinafter more fully de-;

scribed and -zclaimed.

In the accompany-ingvdrawings forming a part .of this--specification, Fig. 1 shows the improved frame in side ele.vation-and having ends secured :to the axle boxes; Fig. :2- is a top plan view showing a preferred con struction of the-.top-of an axle :box for the attachment of the endsoi the'gtruss; Fig. 3 is a sectional elevation on a plane indicated by the line III I II, Fig. 2; Figh 1- is .a sec- ...ti-onal elevation on a plane indicated by the line JV IV Fig. 1; Fig. 5 shows aside and and elevation of .a blank from which the compression and tension =members of the I trussshown-in l are formed; Fig. 6 is a tv-iew similar to F l illustrating a pref terred construction of truss-shaped side .gf uame; 7 is a sectional view on a plane indicated by the line V1I-V1L Fig. 6; and Figs. 8 and 9 illustrate successive steps in the formation of the truss.

In the practice of the invention a rolled bar preferably H-shaped in cross section, the flanges and .web being. :prei erably of nut vform "thickness asshoW-n in Fig. 5, is so cut.

.or slotted for a suitable.distance along its median line as to tonmlegs .a and b. vThe cutting or slotting does .not extend the .en-

40 tire length of the bar, .as it is desired gtlll-t,

the end portions of the legs should be in- .itegral 1one with the other. When forming the truss from an H-shaped section, it isv preferlzedto remove the web ,portion 0 for the desired distance along the bar.

After-the ha r slotted as @described, it is suitably: heated and by suitable mechanism.

one of the legs as a, is upset longitudinally to reduce its length and cause as-bowing out of the other leg. .The extent of upsetting will of course be .dependent upon the desired "depth of :theitnu'ss.

, The {strut of -;the [truss [is next placed in position, said strut being fonmed by a boxlike-casting .into which ends of the bolster and the spring "plank of the t ash project.

The sides of thecasting form thecolumns 1 for guiding the bolster in its vertical movements and also prevent any lateral movement thereof, and are connected by the top and bottom portions 2 and 3 of theoasting, and hence each column. will be rein-- forced as against lateral strains by the other column. The bottom member of the castin forms the support for the spring plank .ot the truck.

The outer faces of the upper and lower= portions of the castingare provided with spaced ribs or checks 5 and .6 forminglateral hearings for the compression r3116]. tension members 7 and 8 of the truss. Suitable of the box or strut longitudinally of the truss, as for example, in .the construction shown in Fig. 1, the upper portion of the box s .rlveted to the compression member .ra nd suitable stops 8* arersecured to the ten- S1011 member .on oppositesides of the casting. The depth .01 the truss,=i. -e., the greatest distance between the tension and compresmeans are employed to prevent movement 1 prevent the box from moving laterally of the truss, ribs or checks 10 are formed on the .top of the box, said ribs being spaced suchdistancesapart that the ends of the truss can be seated between them, and between these ribs 10, a transverse rib 11 is formed, said rib being adapted to extend into a seat '12 formed in the underside of theends of the truss resting on the box. In

shown, the bracket is provided with a seat 14 in which the tension member is held by caps '15 riveted to the brackets. The boxes are secured to the'ends ofthe truss by rivets 16 which preferably pass through the webs c and also the ribs 11 on the boxes.

relatively large or a multiplicity of smaller rivets employed. In the construction shown in Figs. 6, 7, and S, provision is made for avoiding the use of rivets where they would be subjected to shearing action.

,In forming the truss member, a bar preferably E-"l shaped in cross section isso cut or slotted on its median line that thelegs a and 5 formed by cutting or slotting, are integrally connected not only at their ends, but also at a plurality of points intermediate means of a saw or other mechanism, two of the connectingsections, as (Z and f, are severed, as indicated at w, from the leg 6 which in the completed truss will form the tension member, and the intermediate section 6 is severed fromthe leg at, as indicated at 3 The leg a is next upsetthereby bowing the leg Z). The strut is formed by two box-like sections, the sides 1 of which, when the sections are placed in position, form the columns employed for laterally supporting and guiding the bolster. At their upper and 7 lower ends, the box sections are provided with

ribs

16 and 17 adapted to bear against the edges of the compression and tension members, 7 and 8, and each of the sections are so notched in line with the Vertical sides and as'indicated at 18, for the reception of f the inwardly projecting lugs (Z and f on the compression member, as shown in Figs. 6 and 7. The upper ends of the box sections are also provided withfingers 19 adapted to purpose, and are held in such position by rlvets 18 passing through flanges 21 on the r Y, column portions of the section. The frame forming the strut may be made of steel or malleable cast-iron, as best suited to meet the shocks and strains to which the frame would be subjected in use.

In a truck embodying the improvements described and claimed herein,'the load-carrying bolster is supported by the tension member the ends of which rest upon" and are secured to the axle boxes. The load on the tension membertends to deform such mem-- prcssion member.

her and draw the axle boxes and wheelsytowards each other. Such action is prevented by the compression member, which has itsv ends connected to the end of the tension member and to the axle boxes; In the practice of the invention, it is preferred that the positions of the tension member on opposite sides of the column casting or strut should be at such an angle to the correspondingly located portion of the compression member and the ends of the truss be'so secured to the axle boxes, that the lines of stress of the tension and compressionmembers will intersect in a vertical plane coin-' cidlng with the axes of the axles as shown in Figs. 1 and 6 and will therefore so neutralize each other that there will not be any turning movement at the end of the truss. theirends, as indicated at (Z, c and By' It will be observed that in the construction shown in Fig. 6 the strut or frameis held former on integral portions of the truss,

and that the latter is tied to the box by fingers integral withthe latter.

I claim herein as my invention:

1. A side frame for trucks consisting of tension and compression membersrformed of wrought metal and having their ends integrally connected and a cast metal frame interposed between the tension and compression members and forming the columns and springplank support of a truck in combination with axle boxes provided with means engaging the united ends of the tension and compression members transversely and longitudinally, and means for tying the boxes to the tension member. i v V '2. A side frame for trucks having'in combination tension and compressionmembers, each provided with an inwardly projecting lug, a strut consisting of a frame formed of complementary sections, each section being provided with means for engaging the lugs on the tension and compression members, and means for holding such sections in engagement with the lugs. .7

v 3. A side frame for trucks having in combination therewith tension and compression members, a strut consisting of a frameadapted to form bolster columns and spring plank support of a truck, and means integral with the compression member adapted to so engage the strut as to prevent movement of the strut laterally and longitudinally of the com 4. A side frame for trucks bination tension and compression members, the compression member being provided with inwardly projecting lugs and the tension member with an inwardly'projecting having in com lug intermediate horizontally of the lugs on v the compression member, a strut consisting of a frame adapted to form the bolster column and a spring plank support of a truck, and provided with sockets for the reception of the lugs on the compression and tension members.

5. A side frame for trucks having in combination tension and compression members, the compression member being provided with inwardly projecting lugs and the tension member provided with an inwardly projecting lug intermediate horizontally of the.

lugs on the compression member, a strut consisting of a frame adapted to form the bolster column and a spring plank support of a truck and provided with sockets for the reception of the lugs on the compression'and tension members, and fingers on the strut adapted to overlap the compression member.

6. A car truck having in combination a pair of side frames which comprise a bar of substantially H-shape slotted transversely of its web portion and expanded to constitute tension and compression members joined integrally at their respective ends, a strut consisting of a frame adapted to form the bolster columns and spring plank support disposed between and engaged by said tension and compression members and axle boxes secured to the ends of said frame for journalling a plurality of wheel axles.

In testimony whereof, I

my hand.
