Serial No. 572,509.

To all whom it may concern:

Be it known that l, ROBERT E. FRAME, residing at Chicago, Illinois, and being a citizen ot the United States, have invented certain new and'usetul YIniproiven'ients in Car-Undertrarnes, of which the following is a full, clear, and

will enable' others skilled in the 'art to which it apper'tains to inake and to use the saine, reference being had to the accompanying drawings. which illustrate the preferred form of the invention. iiough it is to be understood that tlv; a.. .ention is Vnot limited to the exact d- ;ars of construction shown and described, as it is obvious that various modifications thereof will occur to persons skilled in the art.

In saiddrawings: Figure l is a top plan view of' an undertrame embodying the features ol' the present invention, approximately one half of' the Jtraine being broken away. Fig, l is an enlarged detail tragmenlary plan view of a bolster and connected parts. Fig. 3 is a vertical, transverse section taken on lthe plane indicated by line 3-3 ol'A Fig. 2 and looking in the direction of the arrow. Figjli is a view in side elevation of a. bolster prior to its positioning in the underfranie. F ig. 5 is a longitudinal, vertical section taken on the plane indicated bv line 5-5 ot Fig. l. Fig. (S is a view in the center sill bl anlis. Fig. .7 is a transverse, verl ical section taken on the plane indicated by line 7--7 ol' Fig. l.. Fig. 8 is a transverse, vertical, detail section, taken on the plane ii'nlicated by line ,-8 of Fig. and looking in theI direction indicated by the arrow. Fig. 9 a detail perspective view of one of the/center sill fillers detached.

Referring to kthe details, Af-A indicate the center sills, Y15MB the end sills, and C? f the side sills or' side connecting members,

the center sills extending from end toend of the underl'rame and contacting with and extending beyond the end sills, and being D and connected to the side sills by holsters cross bearers EWE.

Flach ot the 'center sills A comprises preferablv an I-section but may forniot' other coniniercial shapes, and each ot said center sills is cut away at each lend ortion along `the lower edge from a `point inside the respective bolster D to the end ot the sill, the severance .beingr preferably exact description, such asA 1, the web of each greater depth' edge positioned assume the l along a diagonal or inclined line from the i, lower flange of the l wardly to a point adjacent and below the i plane ot the bolster, and thence in la line parallel to the upper flange of the sill to the end thereof. 4

An anglel is fixed each sill A along the end of the sill to the remaining end of the lower flange, a portion of the angle lapping such flange.A Each angle 1 is preferably disposed against the outer face of the to the l'ower edge of respective sill and has its horizontal leg or` flange directed outwardly. Above the angle I -aperture 2, the lower flange receiving portion of' which is'relatively enlarged as at 3 Patented June 11, 1912.

sill outwardly and upfthe cut-away portion from sill A is formed with an 'for allowing the passage therethrough of the flange and also allowing vertical adjustj ment or Inoveinent of the flange vertically, j transversely of the sill within the aperture, i the portion 3 of the aperture being yof than the thickness of the flange to be introduced.

Extending through the apertures 2 of thev I' sills A are the end otl the sills, and only one being illustrated. Each of vthe bolsters comprises an I-section of' less depth than the depth 'of the i reduced end portion of the center sills and having recesses or notches bei in its upper for receiving the remaining web portion andupper sill when the bolster is posi;y

tive center tioned.

In assembling the parts, the bolster D is flange of the respec-v bolsters D, one adjacent each 4,

thrust endwise through the apertures 2, said l course disposed to the ear, and after the bolster has been 1ntroduced and arrives at a position with the recesses 4 immediately beneath the vu per flanges of the respective sills A, vthe bo ster is elevated to a position with the upper surface of its upper fla-nge in the plane of the upper surfaces of the upper flanges A, the recesses 4 being shaped date the adjacent parts ot' the center 'sill sections above the bolster and the adjacent parts of the respective center sill. Prior to the, connection of the-bolster to the side connecting members C, brackets 5 are slid on tothe bolster'longitudinally thereof and are rivetedin position for sustaining the j bolster in its elevated 1 apertures in the respective sills A being of l register transversely of of Sms v to accommo-` positon, and connect# ing the bolster to the center sill sections.

I standing flange ot the '35 Vtio Each bracket 5 preferably comprises' a web shapedv to embrace the lower flange ot' the bolster and to conform to the contour thereof, and extends along the web lof" the bolster and beneath the upper flange, and is providedv with lateral flanges lying flat against the vertical web. Each b upper flanges of the center sills, connecting interrupted portions of the upper flange of A center bearing plate 7 is the web of each bolster eachl side bearing 8 for stittenmg and strengthening purposes. Each ot' the side connecting members-C preferably comprises a Z section, and each end of each .bolster D is notched to receive the web and lower outv Z section, the 'upper flan ela ping the end of the upper flanges .of tle bo ster and. being riveted thereto.

An angle bracket 9, formed of an angle section, is arranged at each side of each end of the web o f bolster and has one of its legsior flangesriveted' to the web of the bolster andthe other flange or leg riveted respectively to the web an lower flange ot' the side connecting member C. As a bracket 9 is provided at each side of the web of the bolster, obviously the rivets connecting the flange of one bracket to the web o the -bolster extend through and connect the corresponding flange of the other bracket..

'Each center 11 spaced apart along` the lengthl ot the center sill between the holsters, and each aperture 11 of .one sill is positioned for immediately above registering with the corresponding aperture in the other. v A cross bearer, compr1sing an said registering .apertures 11 and is con by connecting' brackets .13, embracing the lower portion ot' the cross bearer and having outstanding and pendent flanges fixed to the web of the .resiectivocentcr sill, and flanges extending along the cross bearer andfxed to the web thereof. Each member 13 1s preferably disposed outside the respective center sill but may be otheL vise arranged :1s-found prefered to th noted that the center sills are sill is formed with Lapel-tures able. Each cross bearer 12 has its upper surface lying below the upper flanges of' thc center sills and below thcnpper flange ot' the side connecting' member t), the ends ot each cross bearer being` connected to the upper flanges of the side connecting member C by rivets extending through spacing sleeves or fillers 14. Each end of each cross bearer is notched to receive a portion of the web .and lower Hangc of the respective side connecting member, and a bracket 15 is fixed to the web of each end of cach cross bearer at each side thereof and extends beneath and is connected to the lower flange` of the respective side connecting member.

ach end sill B is preferably a T section horizont-ally disposed and carrying the wood nailing strip 16 formed in sections with the vertical end posts 17 of the super-structure of the car extending downwardly between the sectionsof the nailing strip and having their` lower ends 'fitted into pockets 18 rivete Web of T-section B. lt will be notched or cut away at their upper outer corners vwhere said sills extend beyond the cnd posts 17. while the T-shapcd end sills B rest with their webs above the said center sills, with one vertical flange resting in said cut out and one flange extending upwardly outside` of said end posts 17.

Secured to the center sill extensions beyond the end sills B are Z-shaped members 19, which have one flange outside of the end sills, as shown in Fig. 5 with horizontal web secured in position and with vertically downwardly extending leg` overlapping the ends of said center sills. lnunediatelv below the cover plate 19 is arranged a spacing filler ill), Fig'. extending from the web of one center sill to the web of the other center sill and having' pendent flanges 21 riveted to said webs, the outer end ot' the plate being Yformed with a pendent flange stiffencd intermediate its length b j' a transverse depression Q3. draw bar carrier iron :2l is fixed to the outstanding flanges ot' thc angles 1 and extends acrossI and connects the respective endsrot the center sills beneath member y be offset upwardly between the center sills. Thus it will be, noted that the usual separate striking' casting' commonly secured to thc end sills or to the ends of the center sills is dispensed with, and the center sills, extending beyond the end posts l?, and end sheathing secured thereto serve-*with the Z- plate 19 and filler ideali the functions of' said striking' casting. at the saine. time rcinforcing' the end portions of the underframe and securing' thc end .sillsy and center sills together. Rivetsy 191 pass 'through the hori` zortal web of' said cover plate l!) and into the filler 20 while other rivets 19l serve to connect the vertical la., ...r 1 Y1 9, which comprises a plate Qt), and irfay the pendent leg of the end sill B, thus se curely uniting theseparts. The pendent leg of the cover plate Yll extends downwardly at the' ends of the center sills against thie pendent` flange 22 of the stitfeniiig member Q0 so that the extensions of the center vsills beyond the end sills are stitened and so united to the contiguous parts as to be adapted to all conditions of service without the addition of such striking castings as are gen erally used.
