SIDE FRAME.

Application led September 28, 1923. SerialNo. 665,446. i i

My Ainvention relates,Y to side frames for car trucks and more particularly to a. wrought metal construction of side frame which is very strong and stiff but comparatively light in weight and in which maintenance charges are reduced to a minimum.

One'of the principal features ofthe inventionuesides in the production of a side frame composed of a plurality of separately l0 formed wrought metal sections each having an inner and an outer side wall portion, said Y sections being adapted to be abutted in horizontal planes longitudinally of the side frame .and united to provide a construction of great strength value, said construction forming in effect continuous inne-r and'outer side Walls each having a plurality of top arch bar portions, bottom arch bar portions, and truck Acolumn ortions.

Another object o the invention resides in the provision of a built-up side frame in-V volving a compression member, a tension member and truck column members all of which are formed from relatively small sheet-metal blanks capable of being easily ianged, folded and united, said members being referably abutte relation.

Another object of the invention is to providepa Wrought metal side frame having a tension member, a compression member, and

two intermediate truck column members, the

said members being connected by Welding or riveting yto .provide-'a veryv strong and du.

' iable side frame -whichcan be economically manufactured due to the larve saving of material resulting .from the. tformation of each of said members from -a separate blank of l sheet-metal. i

A still further object of the invention is to provide a wrought metal side frame composed -of separately formed compreion member, tension member and truck columns, the compression and tension members being firmly united at their end portions by means involving abent extension carried.- by one of said" members and adapted to bridge the other, said bent extension beingfirmly con nected to both of said members uponv each side of their junction..

The invention furtherresides in the method of manufacturing car truck side\frames which consists in producing a plurality of separately formed side frame members such as the compression member, tension member,

hereinafter appear.

connected 'in' superimposed and truck .column members, each `ot' said members being produced from .a sheet-metal `blank shaped to provide corresponding side frame .portions lying upon opposite sides of anv axis of symmetry dividin the blank, flanging the marginal edges o each blank, folding said blanks, and uniting the folded blanks with their adjacent edge portions disposed in planes extending transversely of the vertical loads received by the side frame members.

\ There are other features bf the invention A.

pertaining to the particular relation of the parts and details of construction as"'wi1l In the drawings illustrating the invention, the scope whereof is pointed out in the claims: p Figure 1 is a View inside elevation of a wrought metal`car truck side frame constructed in accordance with my'invention.

Figure 2 is a vertical transverse sectional view on the line 2-2 of Figure v1. i l

Figure 4 is a detail cross-sectional view on the line 4--4 of Figure ,1.

Figure 5 is adetail vertical transverse sectional view on the line 5-5 of Figure 1.

Figure 6 yis a detail view in side elevation of a modified form of car truckside frame in which the'ends of the compression member and tension member are integrally formed bridge member extending across the weld joint.

Figure 7 is a top plan View struction shown in Figure 6. l l

Referringy to the drawings in which sim ilar reference characters designate corresponding parts inthe several views, my improved side frame is composed of.a compression member 1, a tension member 2. and

bolster 0r truck column members 3, said 7 truck column',m`embers being adapted to unite the compression and tension members intermediate their ends to form the bolster "opening 4. The side frame members are each formed from a sheet-metalblank having corresponding side frame portions diside of an axis of sym united by an of the coning thektopv' arch` bar port-ions which are preferably shaped to have the eiect of a cambered compression member. Stienmg flanges 7 are provided on the lower edgesp of the top arch bar portions, said iianges being inturned and adapted to. rein-force the spaced side walls `o'f the compression 111cm-,

ber. The lower edges vot the inner and outer side walls of the compression member` between the truck 'columns are also provided with inturned stilening ianges 8, said flanges bordering ,the upper portion of the outer sheet-metal wall 12, said Walls convso " bolster opening. rI `he respective end poi'- tions ofthe side walls of the compression member, and more especially the lower 'ledges 9 thereof, areadapted to be united with correspondingly vormed upper edofe portions 10 at the respective ends of the tension member 2.

The tension member 2 is formed from a sheet-metal blank having corresponding side frame portions disposed upon f each side of an aXis of symmetry dividing the blank. The tension member is provided with an inner sheet-'metal wall 11 and an v' are adapted to be connected to adjacent -of an axis of symmetry edge portions 17 of the truck columns 3.

The truck column members are each formed from a sheet-metal blank having in o ner and outer side wall portions 18 and 19,

respectively, .disposed uon opposite sides Stiti'ening ianges 2O extend inwardly from the outermost edge portions of the truck columns, said stiffening flanges providing ,y contmuations of the tiffening'ilanges 7 of `the compression mem er and the stiiening flanges 13 of the tension member. The inner opposed faces of the truckv columns are adapted to receive bolster wear plates, said inner faces at'their lower ends being offset, as at 21, and continued downwardly to overlie in vertical-alinement the inwardly leX- tending stiflening ianges 14 provided on the upstandingportions of the tension member and bordering the bolster opening. The upper endsof the truckvcolumn members, and more especially the edge portions 22 thereof, are adapted to be united with ad jacent edge portions 23 depending from the compression member 1. The inner opposed l faces of the truck column members provide continuations of the` ividing the blank.'

inwardly extendingy stil'enmg Hanges 8, the'end portions of said .'anges being bent around the -upper corners of the bolster ooeningand disposed to I overlie said inner opposed faces.

The means uniting the ltruck columJns at their respective ends to the compression and tension members involves a plurality of welds 24, said welds being designed to unite therespective abutting edge,4 portions with the inner and outer side Walls of the compression member disposed in vertical aline- *ment with the respective' inner and outer member, .said respective side wall portions being united to produce in eiect continuous integralshee't-metal side walls of maximum strength value. y transversely to the direction ofthe vertical loads received by the side frame. While,y I havev disclosed welding means to efgfect the union of the truck columns with the compression and tension' members, it will be understood that rivets andv othei` connecti-- ing means may also be utilized, it being desirable. however, to maintain the side walls of the compression member in .overlying relation to the side walls of the tension member whereby the vertical load will be transmitted :to portions best adapted to withstand thestrains. l

The compression and tension members are united at their ends b means of a relatively long Weld 25 prefera ly extending'the full The welds 24 are disposed.

side walls of the truckcolunns and tension length of the abutting edges' 9 and 10 of the v respective members. The'side wall portions of the compression member at its ends are adapted to overlie the side wall vportions at the ends of the tension member, the union of said side wall portions at these points providing in effect an integral continuation of the respective inner andvouter side walls of the side frame whereby both the vertical and loo lo gitudinal loads are effectively received by s' thescompression and tension members.

In Fi ure 6 a modified construction is shown w erein the end portions of the comressionand tension membersv are also united y a bendable extension 26 provided on the compression.. member, -said bendable eXtension having flanges 27 disposed against the inner opposed faces of the side wall portions of the compression and tension members, said flanges being connected to the respective sidel walls by means of rivets 28. The flanged portions of the bendable extension are -designed to bridgey the weld joint between the compression and tension members 4and provide a very rigid construction at the end of the side frame. In this construction theJ length of the compression member is slightly reduced to permit of the bendable extension being formed from the same blank without adding materially to the amount of metal used. f My improved method of manufacturing wrought metal car truck side frame consists in forming'each of the side frame members,

sch as the compression and tension members and. truck columns. from a sheet-metal blank havingcorresponding side frame portions which are symmetrically disposed with respect to an axis of symmetry of -the blank passingbetween them, then bending corres onding portions of the blank tov form anges, then bending each blank along aline parallel to its axis of symmetry, and/'inally uniting the respective blanks with their adjacent edge portions disposed transversely to the direction of the vertical loads of the Y side frame, the adjacent side frame portions of the respective sideframe members producing 1n effect continuous mnerand outer side Walls havindglsilnwardly extending stiiening anges relation. I
