Application filed October 30, 1905. Serial No. 285.153.
To all whom, it may concern. 1 Be it known that I, ETHAN I. DODDS, acitizen of the United States, residing at Pull- ='man,-inthe county of Cook and State of Illi broad ends of the bottom flanges, whereby a strong structure results. It will also be found desirable and advantageous to rivet transoms'together, and in the structure described these flanges are integral with the sills andtransverse beams. p In the accompanying drawings I have illustrated my invention, like reference characters on all the figures referring to the same arts. p F igure'l is a face view of the"blank,from which one of the side sills may be manufactured. Fig. .2 is a face viewof the completed sill. Fig. 3 is a plan orv upper'edge view of thesill shown in Fig. 2. Fig. 4 is a vertical section on the line 4 4. of Fig. 2. Fig. '5 is a vertical section on the line 5 5 of Fig. 2. Fig. '6 is a plan view of apart of the car 'underframe; Fig. 7 is a vertical crosssect-ionof the car on line 7 7 of Fig. 6, and Fig. 8 is a-similar view on line 8 8 "of Fig. 6.
Each side sill 1'.) has a uniform int al top flan e 11 extending substantially the full .lengt of the sill, which is provided on its lower edge with an integral flange including the central uniform portion 12, the tapered intermediate portions 13, and the wide end portions 14. A sill of this character maybe economically and readily manufactured from a rectangular sheet-metal blank, as shown in Fig. 1, the longitudinal edges of which may be bent over on the straight line 16 and the bent line 17 18 19 to form the flanges. Besides these side sills the underframe Includes,
spaced center sills 20, tied together at intervals by short channel-sections 21.
broad flanges 14. of t The body-bolsters comprise a plurality of tapered channel-beams 22, spaced apart at their'outer ends by members 23, the inner ends of the beams being fastened to the center sills; by. angle-plates 24; the outer ends of the beains resting u on and riveted to the he side sills, the ends of the upper flanges being riveted to the top flanges 11 of the sills. Flying transoms 25 are provided, the same being fastened to the center sills and side sills by means of angleplates 26 and 27, respectively. Draft-sills 28 are secured to the outer vendsof center 'sill's' 20 andto the face-plate 29 and end stakes 30, the facelate being also connected to the corners of t e car by bars 31. These corners are tied to the draft-sills by means of transversefbars 32 and to the center sills by diagonal angle-braces 33, the, outer ends of which rest upon and are riveted to the wide flanges 14 of the side sills. Corner and side stakes 34 and 35, respectively, also form apart of the structure, as is usual. The carbody comprises side plates 36, end plates 37, and floor plates 38 together with the copingangles .39 and 40 and the angles 41 and 42,
which extend longitudinally and tfans- I versely ofthe car, respectively, the angle bars 39 and 40 being secured, by means of rivets, to the side plates and side stakes and the bars 41 and 42.to the floor-plates and top flanges of the side sills and transverse beams.
It will be apparent that this construction does'away wit the employment of angle and gusset plates for the transverse and diagonal beams without sacrificing strength. The side sills and their method of manufacture form the subject-matter of a co ending application, Serial No. 285,152, fl ed October This patent is intended to embrace only so much of the disclosure made herein as is covered by the appended claims.
1.- In a railway-car, the combination of a I bellied side sill having a bottom flange along its lower margin, said flange having a central portion of uniform width, tapered intermediate orti ons, and wide ends, and transverse eains resting on and secured to said wide ends, substantially as described.
In a railwa3' -car,-, the combination of a bellied side sill having a bottom flange along its lower margin, said flange having a central portion of uniform Width, tapered intermeflange is the same at all points of its length,
' and transverse beams resting on andsecured to said Wide ends of the flange, substantially as described.
3. In a railway-car, the combination of a. side sill having a top flange and a-bottom flange, said bottom flange having ends wider than its central portion, and a transverse beamhaving top and bottom flanges, said top flanges being secured together, the bottom flange of said transverse beam being secured to one of the Wide ends of said sill, substantially as described.
4. In a railway-car, the combination of a bellied side sill having an integral top flange and an integral bottom flange, said bottom flange having wide ends and intermediate 'tapered portions, and a transverse beam hav- -mg inte ral top and bottom flanges, said top flanges being riveted together and the 'bottom flange oi said transverse beam being riv eted to one of the Wide ends of the bottom flange of said sill, substantially as described;
5. In a railway-mar, the combination of a bellied side sill having a bottom flange along its lower margin, said flange having a' central part of uniform Width, tapered intermediate portions, and Wide ends, and diagonal braces resting upon and riveted to the Wide ends of said flange, substantiallv'as described.
