Fig. 6 is a similarly enlarged longitudinal vertical sectional View taken substantially on the plane of line 6 6 of Fig. 1, looking in the v direction'of the arrows, and illustratin details ofcon'st'ruction atth'e bolster. Fig. 7

is a similarly enlarged horizontal fragmentary sectiona-l vieivf taken on the plane of line 7 -7 ofFig. 6, and Fig. 8 is a horizontal sectionalview taken'on the lane of line 8-8 of Fig; 3,, illustrating etails of the cross bearer construction. i

The object of this invention is to provide -a car nnderframe oif'substantial construct-ion wherein the principal longitudinal memelements of the bolster;

larly applicable to the design and arrangement of the longitudinal members.

The invention therefore resides particu of the parts comprising the center sill and of the truss. member of said center sill.

g It further resides in the form of strut elnployed between the center sill and the truss;

memberand the relation of said' strut to the n f ailer resides in the liov'eldesig ii' of draft sillsand in their connection with the;

Since the details of construct-ion of the 'underframe are identical upon'opposite sids of the transverse median line thereof, only one side lies been illustrated in thedrawings and it Wi '1 be understood that a description of one side applies equally to both.

Referring to the details, the numerals 1 1 indicate the side sills; 2 the end sills;

} 3 the body bolster; 45 the center sill; 5 one of the cross bearers of which there may be as many as may he desired throughout the length of the car, and 6 the tie-bars intermediate the cross bearers and between cross bearers and bolster.

The center sill 4 comprises preferably anI section as.7 and a channel section as 8, the I'section beiug'disposed with its Web standing vertically and the channel having its web disposed horizontally-and fixed to the upper surface of the top flange of the I section and having its flanges depending substantially equidistant upon opposite sides of the I sectlon.

' vThe I section may obviously corn rise a I 'pair'of channels placed back to beer or it der surface of the I section intermediate the 1 bolsters so that its end portions only are fixed to the I section, and its intermediate having upper and lower flanges fixed reof the channel Qareconnected by a pair of plates 11-11. The plates 11 are fixed to preferably spectivelyto thelower flange of splice the I sect-ion 7 and to the top surface of the web of the channel 9, intermediate the flanges of said channel. The I section 7 and the channel 9, and also the channel 8, are extended through the bolster, the I section and the channel 9 terminating short of the end of the channel 8 at a point between the end sill 2 and the forwardface of the bolster.

\Vithin the bolster the down-turnedflanges of the channel 8 and the upturned flanges the outer vertically alined' surfaces of said flanges and extend from a point behind the bolster, through -the bolster, and approximatelyto the end of the channel 8.

The draft sills 1212 extend from the endsill 2 to a pointwithin the bolster, each of said sills comprising a channel section disposed with its web standing vertical and its top and bottom flanges projecting outwardly. The inner surfaces of the webs of the draft ,sills engage the outer surfaces of the splice plates 11 and are fixed thereto,

7 y rivets,'some of which fix said plates to the flanges of the channel sections 8 and 9. Others of the rivets which fix the plates 11 to the draft sills 12' serve also to connect the rear follower stops, as 13, of the draft rigging, to the inner surfaces of said plates. It will be observed in this connection that each of said follower stops 13 is sup orted by rivets extending through a dou le thickness of metal, viz :-the plates 11 and the webs of the draft sills 12. As the splice plates extend through and be yondthe bolster at each end and the top' and bottom channels 8 and 9 also extend through and beyond the bolsters it is evident that these members form a box like structure for part of the length. of the sill. It isevident also that the top and bottom channels 8 and 9 with their flanges also form a box like structure for part of the length of the sill though the vertical sides of the box are not'connectcd as in the box com rising the splice plates '11.

flanges as 1515 of the diaphragms are.

riveted directly to the plates 11 and-through said plates, to the flanges of the channels 8 and 9. The outer vertical flanges as 1616 to the bottom flange of the I section 7 Each of the cover plates 17 and 18 terminate short of the outer ends of the bolster diaphragms. The cover plates 17 and 18 are also fixed to the inner ends of the top and bottom flanges of the draft sills and serve to materially strengthen the connection between the draft and center sills. Commercially rolled channel sections,-'sueh as those employed to form the draft sills 12, are not manufactured of a height so near that of the I section center sill as to com ensate only for the thickness of the webs o the channels 8 and9, and for this reason channel draft sills are employed which areof the same height as the I section and small fillersas 12"-12 are interposed between the top andbottom surfaces of the flanges of the draft sills and the contiguqus surfaces of the cover plates 17 and 18, said fillers being of equal t ickness with the webs of the channels 8 and 9, so as to present an even surface for the attachment of the cover plates.

- A center bearing casting 21 and side hear ing castings 21-2l are, fixed to the under surface of the bottom cover plate,l8, said center bearing casting being provided with the usual central kingpin aperture 22. v

The bottom cover plate 18, the web of the channel 9, and the bottom flange of the I section 7, are each formed with perforations as 23--23 in ulinement with the aperture 22.

The web of the I section 7 is cut away as a flanged diaphragms as 27 disposed upon opposite sides of the center sill. The inner vertical flanges 28 of the diaphragms are connected to opposite sides of the web of the I section of the center sill by throu h rivets. The outer vertical flanges 29 of tile 35 are preferably of Z section though they may diaphragms are fixed directly to vertical portions of the side sills. The top flanges are connected together by a top cover. plate as 31 which extends through a suitable aperture'32 formed in the web of the I section, said aperture being sufiiciently removed from the top flange of the I section so that the cover plate extends beneath the lower edges of the downturned flanges of the horizontally disposed channel 8.

There is a strut 10 at the point of each of the cross, bearers and the inner vertical flanges of the diaphragms, comprised in said cross bearers, are continued below the bottom flange of the I section of the center sill and are fixed-to opposite sides of the web of said strut by through rivets as at 32, a cutaway portion 33 being formed in each of the diaphragms to admit the flanges of the I section? andthe upper flange of the strut.

The webs of the diaphragms 27 are disposed with one of their vertical faces approximately in the plane of a'vertical transverse edge, or end, of the strut 10 and a'connecting angle as 34 is fixed to the lower edge of the web of each of said diaphragms and extends across the edge, or end, of the strut for efiectually binding the lower, or compression, portions of the diaphragms to gether.

The bottom flanges as 30'-1-30 of the dia phragms 27 are inclined from the side sills downwardly toward the truss channel 9 and engage the strut 10 at a point spacedsom'ewhat above said truss. The side sills l1 I comprise any convenient or desiredshap'e.

The Z sections illustrated are arranged with their webs standing vertically and their top flanges extending outwardly and adapted to support the side nailing strips as 3535 upon their top surfaces. The top surfaces of said top flanges are arranged substantially in the same horizontal plane as the top surfaces of the upper flanges 30 of the cross bearers and are therefore below the level of the top surface of the center sill and .the bolsters.

The top flanges of both the bolsters and cross'bearers are horizontal from side sill to side sill so that the end flanges 16 of the bolster diaphragms project above the side sills and form pockets for thenailing strips 35. Upstanding angle sections as 3G---36 are fixed to the webs of the side sills and to the webs of the diaphragms 27 at each of the cross bearers, for the same purpose.
