\ CAR CONSTRUCTION.

Application filed December 7, 1922. Serial No. 605,488.

My invention relates more particularly to the method of constructing or reenforcing the ends of railway cars, such asgondola or box cars and comprises means whereby the end structure is IG-QllfOl'CQCl, resistance to load bolster toward the ends of the car.

My invention contemplates meansso dis posed as to act as a cantilever which rests on and is secured to the under-frame of the car and adapted to transmit the strains or shocks to the heavy timbers or members of the underframe; the bracing in reality constituting an integral part of the car structure, with the result that the usual'weakness in the end framing of freight cars, especially of the gondola or box car type, is thereby eliminated and a concentration of strength provided atpoints where the strains, due to shifting loads,are usually concentrated or encountered. a t i The objects and advantages of my invention will be more readily comprehended and understood from the detailed description of the accompanying drawings, wherein Figure 1 is an end elevation of a gondola type of car with the running gear omitted. Figure 2 is a fragmentary view in elevation'of the side of the car at one end.

Figure 3 is a sectional view taken on line 3-3 of Figure tion of the arrows.

Figure 4 is a detail sectional view taken on the line 4-4 of Figure 1.

Figure 5 is a detail sectional view taken on the line 55 of Figure 1 looking in the direction of the arrows.

Figure 6 is a detail sectional view, taken on the line 6--6 of Figure 1. a;

As my invention is applicable to the well known type of composite wood and steel construction of gondola car or box car at present in use, a specific description of the general car construction need not be entered into.

at 1 looking inthe direcrelation with each In the exemplification of the invention, as disclosed in F1gure 1, where one end of a gondola car hasbeen shown composed of the usual plank or timber construction, as shown at 20 in Figure 3, reenforced at the top and bottom by suitable angle irons or members as at 21 with the longitudinal center provided with the usual striking casting at 22 disposed coincident with the usual draft rigging under the floor of the car.

My improved reenforcing -means comprises a structural member 23 adapted to extend from top to bottom at the end of the car and of suitable sheet metal. preferably formed with a longitudinal rib as at 24 disposed substantially throughout the length v of the reenforcing member 23. In the particular exemplification of the invention as disclosed in Figure 1,,the reenforcing rib 24 is shown produced by providing the longitudinal centerof the member 23 with a corrugation" having a rounded exterior surface, somewhat U-shape in cross section, as disclosed in Figure 6; with the ends of the corrugation or outwardly dished portion 'of the member 23 preferably tapering off into the flat end ortions which are shown preferably flare or enlarged. In Figure -1, the upper end of the member 23, where it is flared or enlarged as shown at 23*, is suitably secured to the reenforcing angle iron 21 disposed about the upper outer side of the car; while the lower endisintended to be disposed rearward of and secured to the striking casting or plate 22 and therefore to the underframe or structural portion of the car.

Diverging upwardly from opposite sides of the lower end of the ree'nforcing member 23, I provide the brace members25 25, also composed of suitable sheet metal with. a longitudinally disposed rib or corrugation as at 26,,preferably somewhat of enlarged channel formation as shown. in cross section in Figure 4. The ends of the brace members 25 are also preferably enlarged to provide suitable attachingpoints whereby the upper ends may have lapping relation with and be secured or riveted to the reenforcing angle member 21, whilethe lower ends of both brace members 25 are brought into close other i and preferably rearward of the member 23 so as to permit the same securing means or rivets whereby the lower end ofimember 23 is secured in place to also constitute fastening means or rivets for a portiem of the lower ends of? the brace members25j while theimmediate lower ends of both brace members 25,- whichare also arranged rearward-Jot the sstriIcing; casting or plate 22, are secured to the undertrame by the same rivets or fasteningfnrean's; whereby the striking plate and the lower end of the member 23 are secured in place.

The intermediate portionsof the members 23' and 25, atsuitabl'e intervals,- are "secured to the body or'end' of the car by suitable" bolts and'nuts as at 27 'Tthereby securing the end. planks 20in fl'ush relation' wi-ththe re v enforcing members:

The corners of thezcanflnam'ely" the" jnnc' tu-resbetw'een the sides and ends iof' the' car; are each provided with. reenforcing: memher or angular metallicplate 28 formed tolie Hat with the sides"andendsofthecar' as shown in" Eigures '1, 2i and 5"; the lower ends.ofthe'reenforcing members or p1ate2'8 being preferably flared or enlarged to provide greater attaching and reenforcing" sur; faces at the side and endisil'ls' otthecar' underframe. The members 28 are adapted to extend from a point adjacent to the. top" ot the car to a point prefrablybeneath: the floor level" and therefore in lapping relati'on with the side sills astshowniat 29Fin1Figures: 1 and 2; the lower endsib'eing rigidly secured to the side and end sills while. the upper ends are adaptedtob'e secured'toi the reenforcing; member 21 and that portion of the reenforcin'g members 28 disposed? about the end of the car adjacent the top is pref erably; disposed beneath. and in partial lapping relation with the upper ends of the: brace members25, 25, so" that the-rivets or other securing means"at'the upperends of the brace members :25 will also? constitute the securing means for the upper: portions of the members 28 at: the ends 'of'th'e car; The corner members 28 like. the. members 25, 25 and 23, at sulit'abl' e" the lengths thereof, are also preferably perforated. to receive bolts fbnsecuringthe end and side planks 2'0 'th'ereto.

My improved tripartitecar end reenforcemen't' or inverted tripodal bracing provides a cantilever construction from: body holster out to the end of the car with compression strains being transmitted to the center beam of the car underfi'ame, whereby both side sills and the side" plates are held and supported; while the corner plates 28 i'nreality act as suspension members or. links tohold up the corners'of the'car; the" bracing'oiiering proper resistance to the load thrusts,

points throughout transferring-'1 the shocks to the structural members of the car undertrame; that is to say, my improved bracing serves a threefold purpose, namely providing a very strong end construction ;providing a dia gonallbracing which prevents the sides of the car from spreading ;and acting as a cantilever wh ereby the sides of the car are prevented from drooping down "from the bblster-towardihe ends otthe car, as the tripartite bracingorcantilev'er restson or is securedto the car underframe.

I have shown and describ-ed wha't I believe to be simple adaptations ot-my invention, which has been described in terms empl oyed merely'as terms of description and not as" terms of-limitation, as structural modifications may bemade without, however, departing from the spirit of my invention.

1; In'a composite woodand steel'car construction," provided with a striking casting, an" inverted: tripod brace whereby the compression strains are transmittedto the longitudinal center sill of the' car underframe, said brace consisting" of ametal plate disposed verticallyat'the center of the car end wall, and a pair of metal plates disposed diagonally upward" from the lower end of the first'mention'edplate, the lower ends of the threeplates being arranged in lapping relationintermediate of the car end' si l-l and the striking casting at the longitudinal center line of the car, with said lower ends and the striking casting being" secured to the car underframe, while the upper ends of the three plates are secured to the top reen forcing member" of the car, and suspension members disposed about the corners of the carb'odyin lapping relation with the up per ends of the diagonally arranged plates", while the lower ends are secured to the side and end-sills of the car.
