METALLIC' CAR-UND'E RFRAM'E.

Application'filed October 30. 1905'IA SerialNof 285.154.

To all may concern.- 13e it known that I, I. Donne, a citizen of they United States', residing at Pullman,y the county of Cook and State of Illin-ois, have invented certain new and useful Improvements in Metallic Car-Underframes, of which thel following is a specification.

i For* the side sill of a; car I employ in accordanceW-ith my present yinvention a rectangular metal sheet which has had a flange turned over along its top edge and a com.h paratively narrow flange folded overl along the lowered-ge of its central part` and which has been sheare'd upwardly from its botto-m edge, permittin `wide flanges to vbebent over on the lowerl e es of the end portions, the latter being of essdepth than the central part, the eXtray metal, due to the decreased depth, being taken `upin their broad flanges. The lower flanges of the central and end parts are then.- tied together by a tension-bar .riveted thereto', the body-holsters resting upon and fastened to the broad flanges: of the terminal. portions, dispensing with the usual angle-plates,y and they needle-beams resting upon the bar and the lower flange of the central part of the sill and fastened there-tof. Such a construction isof comparatively light weight, ec nomical in the cost of manufacture,I and a -ords convenient attaching means for the ends of the body-holsters and needle-beams.

In the accompanying drawin s I 'have illustrated the preferred mechanica embodiment of my invention,l like reference characters in all thefigures referring to the: same parts.

Figure 1 is a side elevation of a portion of a car embodying my invention. Fig. 2 is a vertical cross-section thereof adjacent to the body-bolster on line 2 2 of Fig. 1 as viewed in the direction indicated byv the arrows.

Fig. 3 is a fragmentary vertical cross-sectionl of the car near the needle-beam on line 3 3 of f Fig. 1, and Fig. 4 is a fra mentary vertica I flange`14. For the sake of economyinmanufacture a sill of this character is preferably made froma` rectangular sheet of metal by turning over thev top flange 11, shearing the sheet along the parallel vertical lines 15, (of which only one` is shown,) folding overv the bottom flangev 1'2 on the lower edge. of the central portion, and then bending over the wide lower flanges 14 on the bottom edges of the end parts. -A channel; tension-bar 16|, which has its` flanges exten-ded downwardly l and only half of which is shown in Fig. 1', has

central and end

horizontal portions

17 and 18, respectively, and intermediate inclined portions 19, the ywebs of the horizontal portions bein connected by means of rivets to the lower 'a= es` of the end" and central portions of theY sil f, leaving oenspaces*l between inclined portions19 andi flanges 14,

The car-body includesl side plates- 20, side stakes 21, end plates 22, coping anglebars 23?, floor-plates- 24, and the inside angle-bars 25',` which extend len thwise above the side sills and also across t eends of theY car, the outer edges of floor-plates 24 being disposed between the an `le-bars 25 and thetop flanges 11 of the side si ls..

Channel body-bolster beams 26y are'secured to theitwin spaced channel center sills- 2,7'y by means of an le-plates 28, theouter ends of 'their integra-y lower flanges 29' restingv upon the wide flanges 14 of the side sills, being riveted thereto and tothey web.` of thegtensionbar 18, rivets 30 fastening together anglebars 25, floor-plates4 24, flanges 111, and top flanges 31 of' the bolster-beams. Needle'- beams 32, with their integral top and bottom flanges 33 and 34, respectively, are similarly secured to the center sills by means of angleplates 35, rivets 36 fastening together anglebars 25, floor-plates 24, and flanges '11 and 33, the lower flange 34 resting upon flange 12 and the web of tension-bar 17, rivets 37 securing together flanges 34 and 12 and the web of the bar and rivets 38 securing together flange 34 and the web of the bar. At,-

tentionis directed to the fact that the needle` IOO IOS

My improved: construction embodies side sills which are light in weight,but which nevertheless possess great strength, besides affording broad supporting means for the outerl ends of the body-bolstersand needlebeams. It will be apparent that the channel tension-bar securely ties together the cen-n l much of the disclosure made herein as is covlered by the claims.

f .I claimv l. A metallic sill for a railway-car having adjoining rectangular central and end parts,

said central part being of greater depth than said end parts, and a bar secured to the lower portions of said central and end parts, sublsaid. central part being of greater depth than said end parts, and abar secured to the flanges of said central and end parts, substantially as described.

4. A metallic sill for a railway-car having integral rectangular central and end parts,

said central part having a flange along its lower edge and said end parts having wider fianges along their lower edges, and a bar secured to the flanges of said central and end part-s, substantially as described.

5i. A metallic sill for a railway-car having integral rectangular central and end parts, said central part being of greater depth than said endparts, said central part having a flange along its lower' edge, and said end parts having flanges along their lower edges, the

width of said latter flanges equaling the difn ference in depth between said central and end parts plus the width of the flange on saidcentral part, substantially as described.

6. A metallic sill for a railway-car having integral yrectangular central and end parts, said central part being of greater depth than said end parts, said central part having a flange along its lower edge and each end part having a flange along its lower edge of a width equaling the difference in depth between said central and end parts plus the width of the flange on said central part, and a channel-bar whose web is riveted to the flanges of said end and central parts, substantially as described.

7. In` a railway-car, the combination of a side sill having a bottom flange along its central part, a bar wider than said flange riveted thereto, a needle-beam having a bottom flange, rivets securing together the flange of said needle-beam, the fiange of said sill and said bar, and additional rivets securing together the fiange of said needle-beam and said bar, substantially as described.

8. In a railway-car, the combination of a side sill having a bottom flange along the central portion thereof, a channel-bar, the web of said channel-bar being wider than said flange-and disposed beneath the same, a needle-beam having a bottom fiange, rivets fastening together the flanges of said needlebeam and sill and the web of said bar, and additional rivets fastening together the flange of said needle-beam and the web of said bar, substantially as described.

9. In a railway-car, the combination of center sills, side sills, and needle-beams fastened to said center sills and side sills, said needle-beams being of greater depth at their outer ends than at their inner ends, substantially as described.

Signed by me at Chicago, Illinois, this 27th day of October, 1905, in the presence of two witnesses.
