l f cangnnnnrama Be it known that I, WILLIAM N. OEHM,
a' citizen of the United States, `and resident of Michigan City, countyof Laporte, and Stateof Indiana, have invented certain new and useful Improvements in Car-Under'- frames,vof which the following is a spec1` fcation, and which are illustrated in the accompanying drawings, forming a part thereof.
The invention relates to car underframes, and the object of the invention is the provision of a frame, the metal composing which is arranged in the most eflicient man'- ner for the resistance of stress and to increase its life as affected by corrosion. In general the arrangement of the metal for this purpose consists in an unusual concentration of the metal in the flanges of the structural shapes used, and, in some in-` stances, of the, marginalportion of the web.
In the accompanying drawings: p
Fi ure 1 is a side View, partly in section, showing the center sill of a car body and a cross bearer attached thereto;
Fig. 2 is a transverse section on the line 2--2 of Fig. 1;
Fig. 3is a horizontal section taken on the line 3 3 of Fig. 2, of a cross bearer;
Fig. 4 is a vertical section of a cross bearer taken on the line 4-4 of Fig. 2;
Fig. 5 is an end view showing a portion of a bolster, and the end of a center sill;
Fig. 6 is a horizontal section taken on the line 6 6 of Fig. 5;
Fig. 7 is a` vertical section through the bolster taken on the line 7-7 of Fig. 5, and
Fig. 8 is a vertical transversel section through a center sill showing a modification.
In the drawings 1 indicates the. center sill, 2 indicates the cross bearer, 3 indicates the bolster, 4 is used to designate the top cover plate for the center sill, 5 a cross bearer top cover plate and 6 a bottom cross bearer plate, and 7 designates a topcover plate for the bolster. A side sill of the car is shown at 8. -9 designates `the web of the cross bearer, while 10 designates the web of the center sill. It will be noted that the center sill, as shown in Fig. 2, has the flanges 11 shown thicker than the web 10 and in this instance the thickness of the flange is carried into the web a distance substantially equal to the width of the flange. To the aback of theflo'we'r portion` of the web,

shown in F ig.,2, an angle member 12 may be rivetedto `provide'increased tensile stren the bottomrof this member. It will a so be noted from the showing of Fig. 3, that the endr flanges 13 ofthecross bearer are thicker than the webv thereoffand are ofusubstantially the sameA thickness asthe top and bot- The provision of flanges running continuously about'each margin of the cross bearer `tom flanges llt-and y15 of the cross bearer.
roduces a cross bearer whichis pan shaped 1n generalA configuration.
`The top cover plate for the center sills, shown at 4, has its edges, for azwidth substantially equal to the width 'of the flange of a center sill, thickened, asshown at 16. The opening in the bolster for the king bolt is shown at 17 and this portion of the frame presents no unusual feature. The thickening of the flanges ofeach of the channelshaped members, as well as themargins of the cover plate described, is provided to supply eXtra strength where the greatest stresses occur and .since these regions are the vpoint of attachment of rivets, the construction has the additional function of pro.- viding added holding power for the rivets. Moreover, since the greatest corrosion of the frame occurs naturally at these points at the margins of the ine-mbers, especially at the lower margin thereof, the added thickness of metal at these points will give added' life to the car frame since it will, of course, take longer for corrosion to weaken the members. This relative thickness may be attained by making the webs of less thickness than usual thereby giving the usual strength with a smallerv amountpof metal or it may be provided by making the flanges thicker than is the usual practice, thereby using more metal than usual but at the same time producing a frame of greater strength. The modification of the center sill shown at Fig. 8, shows a web which tapers from below upwardly and, as illustrated, has its lower flange thicker than its upper flange. This modification might be applied to each of the other structural members shown, but its illustration in connection with the center sill is believedto be a suflicient disclosure.
I claim as my invention:
1. A car frame comprising center sills, b olsters, cross bearers andcover plates, the thickness of the metal of all of said members .so graduated as to provide increased thickness where greatest stress and greatest corrosion normally occur. .p
2. A ea-r frame comprising a member channel-shaped in cross-section, the flange m said channel and a portion of the web thereof being thicker than the remaining" portion of the web, and an angle member attached to the back of said channel With one flange of the angle in alinement with said flange, the increased thickness of the web a gi\'inl, q added strength to said attachment and increased resistance to corrosion.
3. A' car frame comprising a member ehannel-shaped in cross section, a flange of the channel and an adjoiningy portion of the web thereof being thicker than the remaining' portion of the Web.
l. A car frame comprising a member channel-shaped in cross-section, the lower flange,- of said channel being thicker than the web and the upper iange thereof and the web being thicker at the bottom than at the top.
5. A car frame comprising longitudinal center sills channel-shaped in cross-section, a cover plate connecting said sills, and crossbearers projecting from said sills, each of said members being thicker at its margin than at its center portion whereby increased 3 rivet-holding power, increased strain resisting' power and increased corrosion resisting power are secured where most needed. (l. A car trame comprising' longitudinal center sills channel-shaped in cross-section, a cover plate connecting said sills and attached to the upper anges of the channels, said cover plate being thicker at its area of attachment than at its middle portion.
