To @ZZ whom t may concern.'

Be it known that I, THOMAS R. BROWN, a citizen of the United States, residing et New York, N. Y., have invented a certain new and useful Improvementin CarBol'sters, of which the following is a full, clear, and exact, description, such as AWill enable others sln'lled in the art to which it appertains to. make and use the same, reference be' had to thel ac'- companying drawings, forming part of speclication, in Winch- Figure .1 1s a side elevation of a bolster embodying my invention. Fig. 2 is 'atop plan view of one-half of said bolster, and Fig. 3 is @detail perspective view of one of the members which forms part'of the bolster.

'member ent at ap 4 and doubled or folds back'so as-to reducejoined together by 'an integral y Another object of my invention 1s Ato pro-- This invention relates to car-holsters, and

has for its object to rovide a novel form of bolster in which eac of the members that project laterally from Athe center sills is tormed b a vertically-disposed continuous 'rom'mately its center two approximately parallel piecels) t tlare vide a bolster a a bottom plate or com.L pression member which bent fornil pro- Jections that 'constitute suie'bearings The bolster herein shown is designed prin! cipslly for use in teIik-ca1's, and, refe the drewings, 1 designates the center sills of a car, and-2 is a'cas interposed between the center sills andprovided with an opening to receive e. king-bolt. Projecting laterally from each center sill is e member consistoi a continuous piece merQiaIIy-.mued channel ent 'at a roxi'- mately its center and doubled or olde back so as to produce two'pieces 3, which are con-f nected together at their outer ends bi an inl tegral web 4. At theinner end of eac ofthe continuous bottom pieces 3 is a flange 5, through which the fasteningdevices (i entend that secure'the member A to the center sill. A, continuous top plate or tension member 7 1s connected to the upper ilanges of thelmembers A, and a late or compression member 8 is connecte to the lower-flanges of seid members.- Preferably the compression late 3 is bent'tc form two projections 9, which constitute side bearings of the preferably a comv bolsters, and a center bearing 10 isfastened to said plate and to the center sills, as shown inFig.1. ,55 At the' ends of the bolstersl are castings, each of which consists of'aibearing-facell and an approximately Usha d flange 12, that embraces the web 4, Whic connects the pieces 3 and also portions 4of lthe webs of said, lo pieces, a strengthening-rib 13 also being" ormed integral with the bearmgface and the Y u wardlyeprojecting fl e 1 2 of said casting. l ecastings are secure to, the bolster by means of fastening devices 14, extending 65 through the flange 12 and vthrough the webs y ofthe pieces 3, and also by fasteningdevices l 15, whlch extend through the bea -face 11 and through' the bottom flanges ,of e pieces 3, the"bear1ngface .of thecasting being araned underneath the .bottom il of y 'sai pieces'.

Fur-V thermore, while* prefer to use commercially- -rolled shapes for the members Ait will'of course be understood that pressed metal plates could be used or merely a continuous stri bent midway its ends and folded back.

produced which gradually diminishes in width from the cent-er sills toward its outer if desired, however, the members A could be so formed that the pieces 3 were perfectly parallel, and therefore l do not Wish it to be understood that my invention is limited to the exact construction herein shown.

Having thus described my invention, what l claim as new, and desire to secure by Letters Patent, is

1. A bolster in which one of the members consistsof a vertically-disposed metal strip that is bent intermediate its ends and folded back substantiallyas described.

2. A bolster in which one of the members consists of a vertically-disposed metal strip bent intermediate its ends and folded back, the ends of said strip being bent laterally to formconnecting-ianges substantially as de.- scribed.

3. A bolster which one of the members consists of a commercially-rolled shape that is bent intermediate its ends and doubled back to produce two vertically-disposed pieces that are connected by an integral web substantially as described.

4. A bolster in which one of the members that projects laterally from the center sills consists ofa commercially-rolled shape which is bent midway its endsand doubled back to produce two vertically-disposed pieces ar ranged side by side; substantially as described.

\5. A bolster in which one of the members consists of a commercially-rolled shape that is bent intermediate its ends and doubled back to produce two vertically-,disposed pieces that are connected by an integral web, and connecting-flanges at-the free end of said pieces; substantially as described.

6. A bolster in which one of the` members consists of a vertically disposed flanged piece that is bent intermediate its ends and 4doubled back, the flange being disrupted atv the point where the piece isbent; substan- 7. A bolster in which one of the members consists of a verticallydisposed anged' that is bent intermediate its ends and folded back, said channel being so arranged that its channel being disrupted at the point where the channel is bent; substantially 'as described.

10. A bolster in which one of the members consists of a commercially-rolled channel that is bent interreediate its ends and folded back, said channel being vertically disposed, and 'connecting-flanges at the ends of said channel; substantially as4 described.

1 1. A bolster in which one of the members consists of a commercially-rolled shape that is bent midway its ends and folded back to produce two vertically-disposed pieces, and

connecting-flanges at the ends of said pieces formed by bending the web of the channel laterally, the flanges of said channel being disrupted at the points where it is bent; substantially as described.

transversely-extending plate that is bent out of its normal' plane, intermediate its ends, to

form a plurality of bearings; substantially as described.

16. A tank-car 'bolster which is of less width at its outer ends than' at its center, and castings secured to the outer ends of said bolster, said castings being provided with bearing-surfaces on its under side; substantially as described. .I

17. A tank-car bolster whose vertical members converge from its center toward its opposite ends and castings provided with horii zontally-disposed bearing-surfaces and being located on the underneath sides of the opposite ends of the bolster; substantiallyas de-v scribed.

18. A bolster comprising members which I project laterally from the.` center sills and each of'which consists of a `continuous strip that is bent midway its `ends and folded back, flanges at theends of said strips to receive fastening devices which connect them ,t0-thecenter sills, and continuous to and bottom plates connected to said mem ers; substantially as described.

19. A bolster comprising members which projectV laterally from a center sill and'each of which consists of a channel that is bent mid-- way its ends and folded back to produce tw'o pieces that diverge from the point Wherel they are joined, flanges at the innerends of -said pieces which are fastened to the center' sills, continuous top and bottom plates, and

i castings at the ends of the bolster and each the bolster, said web members being provided with top and bottom flanges, and a casting at each end of the bolster; substan- 15 tially as described.

In testimony whereof I hereunto aflix my signature, in the presence of two witnesses7 this 26th day of November, 1906.

consisting of a flange that embraces the bent portion of the channel, and a bearing-face which is secured to the lower flange of the channel; substantially s described'.

20. A oar-bolster comprising vertical web I members converging toward the ends of the i bolster, top and bottom cover-plates, and a I casting at eachend of the bolster; substantially asdescribed. l

21. A car-bolster comprising vertical web members which converge toward the ends of Witnesses:
