of the United States, residing at Paterson, New Jersey,

have invented a certain new and useful improvement in Car-Underframes, of which the .following isa lull,

. clear, and exact description, such will enable others skilled in theiart to which it appertains to makoyand use the saine, reference being had to the accompanying drawings, forming part'ol" this specilication, in whichHs Figure l is a plan view of an undorlrame constructed in accordance with my invention; Fig. 2..is a side olc vation thereof; Fig. 3 is a longitudinalsectional view taken through the center ofthe frame, Fig, It is a cross sectional View taken on the line Ll-llof Fig. l; and Fig. 5 is a cross sectional view taken'on the line 5 5 Tli larly toithe underlram'ing of cars.

The object 0f my invention is to provide an underrame which is of simple construction but very strong. Referring to the drawings which represent the preferred yform of my invention, l designates the center sills which are preferably I-beams and these sills may either be continuous or spliced adjacent the bolster by means of splice plates 2,' the latter construction being preferable. v l

The platform end sills 3 consist of channels having top cover plates 4 connected to the upper flanges thereof. The end lsills consist o lianged membersl 5 connected their outer ends to the side sills 6 and-at their inner ends to the center sills l, said members being-of uniform depth throughout the major portion of .their length but increasing in depth adjacent the cen* v terlsillaas shown in Fig. 4.

The bolster' consists of two members, A spaced quite a distance from each other, as shown in Fi'g. l, each of said members consisting of pairs of flanged diaphragins 7 placed back to back and connectedto the center sills and side sills and a tension platev 8 and compression plate 9 connected to the flanges of said diaphragme.

' and to the side sills, as shown in Fig. 5.

' bolster member,` and to insure a very rigid construction I luse an additional bottoni coverplate l3wl1icl1 extends from the insidebolster member to the dra-lt sills, as shown'in Fig. 3. lThis additional cover plate is connectedvto the lower flanges of the center sills and nvention relates to railroad cars and particuyis bent downwardly with the bottom cover plate ll and connected to the end flanges of the draft. sills l2, the compro ing underneath this cover plate The draft rigging casting 'ld provided at its uppcrend with a flange l5 which rests on the inside lower llangos oi the center sills and said ca' ing is riveted to the webs oi thc ccntcr sill and to the webs of the draft sills, as shown in Fig. lt, a llangcd diaphragm lti being interposed between the center sills above said casting. Fillers 17 and a king-bolt casting .i8 are interposed between the' center sills` internleliliato the bolster members, and flanged diaphragme lll are arranged between the center sills at the points where the bolster members are connected thereto.

ion plate ol the bolster members cxtcnd- Diagonally'extending braces 20 are connected at;

their outor ends by gusset plates to the side sills an end sills, an l at their inner lends to the center sills and one of the bolster iilclnbers. lransverscly extending lloor supports 2l are connected to the side sills and center sills, and ldngitudinally extending stringere 22 are connected to said lloor supports and to the end sill members 5." Extending from the end sill to the platform end sill are two parallel angles 23 and also two angles 24 arranged underneath the angles 23,

' the platiorn'l plate 25 being connected tothe angles 23.

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

l. An underfrnme comprising center sills, drnlt sills connected tothe lower sides of the center sills, and :l bottoni cover plate connected to the center sills and ,bent downwardly underneath -the draft sills; substantially as le-i scribed'.

L. An underlrune comprising cellier sills, draft sills connected to the underneath sides or' lhdconter sil nnd provided :it their ends with llanggos, :l bottom cover plate connected to the center sills and bent downwardly to engage the end llnnges ol' the dl'ul't sills to which they are conA nected; suhstzullizully :is described.

'Il An undcrfrnme consistingl ol' [lang-od conter sills, pressed metri! draft sillsconnccted to tho center sills :Ind having inclined end `ll:1llges. n bottom cover plato secured to the center sills :1nd to lthel inclined hongos ol' the draft sills, and n reinforcing' plate extending from the bolster lo the drnlt sills and being;- connected to the ond llnng'es of. said draft sills and to the bottom cover plate for the center' sills; substantially :is described.

l. An undel'l'rzlnle comprising llzlnged center sills having di" sills connected tov-the lower ilnllg'es lhcrcoffund n casting' resting' on the nzlug-cs ol" thecentor sills and riveted to the webs oi' sn'id sills nndlto the draft sills; suhstzlntzllly :1s described,

All umlert'rnlnc comprising 1li-urged center sills having channel-swiped draft. sills connected to the lower flanges thereof, the legs 0l' sold cbnnncl projecting; outwardly, :1nd :rl-ostina' connected to thev wells et' -thc center sills and drzli't sills; substantially ns described.

vt5. An under-frame comprising flanged center sills, channel-shaped draft sills connected to the bottom flanges of the center sills with their flanges projecting outwardly, a casting hnvingi, 'n Flange which rests onthe lower flanges of the center sills, said casting beting connected to the webs of the center sills :ind draft siils, and :i flanged diaphragm arranged between the center sills above said casting; sub4 siuntizilly :is described.

7. An underfrninc comprising centerI sills, side sills, two bolster members spaced :ipzirtfrom eiieli other, each of said members consisting of pairs of flanged diaphragme lconnected to the center sills and side sills, a. continuous tension piatte extending;l over the center sills und connected to said diaphrng'ins, :ind :i continuous compression plate extendim.;l underneath the center sills und connected to said (linphrngms, theonter ends of said compression and tension plates being;- connected to tile side sills, and n center bearing casting secured to :the center sills midway said bolster members; substantially as described.

8. An nnderframe comprising center sills, side sills and two parallel bolster members spaced spart :1nd connected to the .center sills .and side sills, sold center sills being spliced intermediate the bolster members; substantially :1s deseribed.

In testimony whereof I hereunto zltlx my signature in the presence of two witnesses, this 30th day of November 1.906.
