To all whom it m zv-y concern:

Be it known that L'Gnoncn 1. KING, a citizen ofuthe' UnitedStates, residing at Middletown, Pennsylvania, have invented a certain new and useful Improvement in Car-Underframes, of which the following is a full, clear, and exact description, such as will enablev others skilled'in the art to portion of my improved underframe; Fig.

4 is an elevation of one of-the. end sills of I any-improved .underfra'me; Fig. is an enlarged transverse sect-ion taken on the line 5-5 of Fig. 1;.Fig. 6 is an enlargecbtrans- I verse section taken on the line (5-6 of Fig.

1; Fig. 7 is a vertical section taken on the line 77 of Fig. 6.; Fig. 8 is a detailed section illustrating a. modified forin of the connection between the end of the crossframe or bearer and the side sill.

invention relatcs to a car undcrframe particularly intended for use in connection With gondolas, flat cars and. box cars, and

my improved construction consists essentially of a box girder center sill,-side and intermediate sills, body, bolsters and cross bearers or frames, all of which parts are constructed ofcrdinary rolled shapes and plain plates cut and bent. as desired, thus materially reducing the cost of constructim'r izing special shapes or castings. I

of underframcs as compared to frames util- My improved construction also provides for the ready repair of the umlerjtrame,

should. parts thereof become broken or unfit for service.

In my improved construction of underconstructed and arranged so that the reator portion'of the total load 'upon the underframe, and the stress thereof, is transferred to and carried by the box girder center sill.

To'the'above purpose'my invention consists in certain novel features of construcmore fully described and claimed. 1

Speciiieationof Letteis Patent. .Patent d J l 1911" The central member of the underframe or i thehox girder center sill comprises a pair of sills 1, preferably in theform ofchan-. nels arranged baclt to back and spaced apart and extending continuously from one 9 end of the frame to the other. The bottom flanges and lower portions of these channels are cut away for a suitable-distance at each end to provide proper space for the -bolsters, and arranged above and below the sills are top and .bottom plates 2 and 3,

which are riveted to the flanges of said sills,

thus forming the box girder. K

The cut-away end portions of thechannels 1 are reinforced at bothtop and bottom by members 1 prefierablyin the -I'or n of=, angle bars-the vertioal'legs of whit-.11.; are.

riveted to the webs of saidchannels 1.

The ends of the bottom plate 3 terminate adjacent the points whcre the lower. flanges of the sills 1. are cutaway and the ends of" the topplate 2 terminate outside the points occupied by the body bolsters.

-4 designates. the side sills of.the under- I frame which are preferably in the form of channels arranged with their flanges pro-' ctin inward toward the lolwitudiual cen- 1 I? h ter of the frame and the upper flanges of said side sillsoccupy a planeslightly above the. top of the box girder.

The, ends of the box girder center sill and side sills -'t are connected in any suitable cast metal striking plates 7. I

Angular-plates 8 of malleable metal and provided with push pole pockets 5) are fixed to the ends of each end ,sill. and conuect the same with the cnds.-of the side Fixed to the inner face. and uppe'fportion of each end sill 5 and tothe ends of the .side sills 4., is a horizontally disposed gusset plate '10, which materially reinforces the end sill and the central portion offthis gusset plate is bent upward as designated by 11 in order to clear the drawdiai and .draft 'gear' arrangedbet-ween the ends of the channels 1 forming the center sills.

.Rigidly fixed. to the inner faces of the channels 1 between theend sills and the ends of the top plate 2 are draft lugs-12, preferably against which the draft gear or rigging engages.

plates 13 and on opposite sides thereof are prising a pair of vertically plates 13 arranged between the channels 1 The body bolsters of my improved underframe are of the built-up type, each comdisposed web ber 18 of a center bearing. Fixed to the upper portions of the-web angle bars 19. and fixed to the horizontal legs of these angle bars is a-tie extends above the box girder.

"lfhe ends of intermediate'sills 21, preferably of wood, bear upon the tie plates 20 and form a base to which the floor 5220f the Transverscly disposed Z-bars 23 are arranged between thece'nter sill and the side sills at suitable points throughout-the length of the frameand which Z-bars form'supports for the intermediate sills 21.

Cross bearers or frames ale attranged on my improvaal under-frame between the body bolsters and preferably at such .points as will divide the space between said body bolsters inlo three equal parts. Each of these cross lx-arers or frames comprises a pair of channels 74. and 25 arranged hove and below the center sill and the ends of said channels be ing connected to the side sills 4 by means of angle plates 26. 'The upper channel 244s bent dpwnward over -the upper cornersof the box girder in order to providesutficient space for the intermediate sills 21. W'cb plates 27 have their-upper and lower cdg-s fixed to the flanges on the sides of the channels 24 and 25, and thus a. cant'aliver cross frame is provided which is comparatively simple in construction and which forms an eil'ective support and connectibn between the central portions of the side sills and the central portion of the girder.

28 designates auxiliary side sills of wood,

which are fixed upon the outer faces of the side sills 4 in any suitable manner. The tops otsaid auxiliary sills 28 occupy the same horizontal plane with the tops of the interas supports to which the of cast. steel, to form shoulderswhich plate 20, which bent upwar ""sills of the underframe,

mediate sills 21 and said auxiliary sills serve I outer ends of the floor boards are attached.

In Fig. 8, I have shown a side sill which is Z-shape in cross section and which form of sill can be advantageously employed in some instances.

It will he noted that the plate 10 is flanged upwardly along its outer edge, and this up.- wardly disposed flange is secured by the rivets 10 to the web of the end sill. 'Also the angles I extend rearwardly of the bolster, the bottom angle 1 extending rear- .wardly to the deepest portion of the center sills, as shown in Figs. 2 and 3,

- An underframe ofmy improved construc- I tion is comparatively simple, is made up of ordinary commercial shapes and plain plates, can be readily and cheaply obtained, and said underframe is so constructed as to be easily and cheaply repaired when necessary. By providing the intermediate sills and auxiliary side sills of wood the floor boards canbe readily placed in position upon the underframe without any machine work -or cuttmg away on the under side.

I claim: e 1. In acar underframe of the class described, the combination with a flanged end sill, of a horizontally disposed gusset plate fixed to the inner face of said end sill, and the central portion of which gusset plate is 2.
