Specification of Letters Patent.

Patented Jan. 16,1912.

Original application filed July 18, 1910, Serial No. 572,509. Divided and this application filed November 9 residing at Chicago, Illinois, and being a citizen of the United States, have invented certain new and useful Improvements in End Underframe Construction for Cars, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and to use the same, reference being had to the accompanying drawings,'whieh illustrate the preferred form of the invention, though 'it is to he understood that tl'ieinvention is not limited to the-exact details of construction shown and described, asit is obvious that various modifications thereof will occur to persons skilled in the art.

In said drawings: Figure 1 isa plan view of the end portion of the'underframe of a car constructed in accordance with the in vent-ion. Fig. 2 is a vertical transverse sectional view taken on the plane of line 2-2, of Fig. 1. Fig 3 is a vertical longitudinal sectional'view taken: on the plane of line 3-3,, of Fig. 2, the central end post being omitted, and Figs. L and 5 are detail perspective views, V i

The object of this invention is to provide an endunderframe construction for railway cars wherein end portions of draft sills are provided with end cover-plates connected with end sills of preferably commercial sections and reinforced as described in my application for Letters Patent,- Serial No. 572,509, filed July 18,1910, of which this application is a division.

Referring to the details; numeral 1 indicates the end sill of'trhe structure; "2-2 the'adjacentend portions of the draft sills; 3 the end posts of the superstructure; the end nailing strip; 5 the end sheathing and 6 the longitudinal stringers to which the flooring 7 is fixed. 1

Each end sill 1 is preferably a. T section horizontally disposed and carrying the Wood nailing strip at which is :tormed in sections, the vertical end posts 3 wardly oetween the sections and having their lower endsfitted into pockets 8 riveted to the web of the T section end sill.

The various sections of the nailing strip are notched along their forward lower edges to receivethe upstanding flange of the end the drawings.

sill. The lower ends of each of the posts 3 are likewise notched as shown in Fig. 5. 56

sheathing 5 is fixed to said posts and to 60 said nailing strip sections in any approved manner, and its lower edge is extended downwardly so as to overlap the forward face of the end sill as best seenin Fig. 3 of -'lhe position'of the lower ends of the posts 3 in the post-pockets 8 fixed to the horizontal-flange otthe l" end-sill, hack of the upstanding" flange of" said sill, together with the fact that the several sections of the nailing strip Qare likewise new behind said flange, renders it practically impos s1ble forlsaidmembers, and with them the end sheathing, to, he forced or bowed out v wardly, as is often caused by the shifting longitudinally of-heavy loads within "the an; rea ed stash employed, beyond. furnishing the upstemding dangeftor re taining the post-pockets and nailing strips 30 as described, possesses numerous other advantages inherent to the "J" section over ends sills of other commercial shapes, among which advantages may he noted the .iact

that the stem or'horizontal flange aiiords an excellent means of connectingthe sill with dre'tt sills, and incideutall3, connecting the top flanges of the draft sills. The downwardly extending portion oi the "vertical flange, aside troi n .110 fact that 511 adds greatly to the strength oi the end frame, forms'an abutment vertical. faces of the cut-out portions 9 (f the draft sills "for assisting the strihingplate of the structure in withstand. as; the butting and said d pending" flange, also Lt OIIl'IS an excellent means for receiving rivets by which the rear portion of the Sill V i A. further material advantage jot the "2" section end-sill member in the fact til the"? section d"posed shown in applicant is c-onsidc )lv stron er for absorbin 29 U butting thrusts than other available shapes of the same weight consistent with simplicshocks of 5 beyond the end sill, is a Z-shaped plate 10 last point is ,ver

22 project beyond the draft sills are notched or cut away at their upper outer corners, where they extend beyond the end sill as at 9. The T-s'haped end sill rests with its web above and is riveted to the top flanges of the draft sills, with the lower part of its VQItICSl flange resting in said cut-out portion and the upper part of said flange extending upwardly and serving to retain in position the nailing strip sections and the post'pockets. Connected with the draft sill extensions,

The draft si s end'sill and'said which has an upwardly extending flange 10 outside of and parallel "with the end Slll, shown in Fig. 3'and a horizontal web 10 secured in position above-the extended portions of the draft sills and a downwardly extending 'leg 10 overlapping the vertical eiidsaof said-draft sills. Immediately below the plate 10 is fixed a spacing filler 11 v 1 shown'detached in Fig. 4 which-comprises transverse depression 13.

one; draft sill and preferably a pressed plate extending from the web of one draft sill to the web of the having pendent flanges I1 rivetjd to said webs, the outer end of the plate being formed with a pendent flange 12 stiffened intermediate its length by a A draw bar carrier iron 14: is fixed to the under side of the draft sills and extends across and connects said sills beneath the filler 11, and may be offset upwardly between the draft sills as shown in Fig. 2.

The lower edge of the pendent flange 10 of the striking plate 10 is spaced above the upper surface of the draw bar carrying iron 14, so as to form the usual draw bar opening as at 15.

It will be noted that the usual separate striking casting commonly secured to the end sill or to the ends of the draft sills is sills,

dispensed with, and the draft sills extending beyond the end sill, and end sheathing secured thereto, serve-with the Z-plate 10 and filler 11 all the functions of said strik ing casting, at the same time said plate 10 and filler ll serve to reinforce the end portion of the underframe and to secure the assthrough the horizontal web of the cover plate 10 and into the ,filler 11 while other rivets 17 serve to connect the vertical leg of said plate 10 with the-pendent'flange of the end sill, thus securely'uniting these parts. The pendent leg 10 of the plate 10 extendsdownwardly at the ends of the draft against the pendent flange 12 of the filler 11, and is riveted thereto so that the extensions of the draft sills, beyond the end sill, is stiffened and so united to the con" Rivets l6 tiguous parts as to be adapted to all conditions of service withoutthe addition of such striking castings as are above referred to.
