f members of the car. Y In such a structure the impact of the shifting cargo against the end wall is carried by the embossments acting as beams to the vertical flanges, which united y flanges then become a horizontally loaded l5 vertical beam between the upper and lower longitudinal frame members of the car.

The place of attachment of the flanges of the adjacent plates forms a weak spot in the above mentioned vertical beam and it is an ao object of this invention to reinforce this weak spot with a member which is a splicer, a stifyfener and also means for attaching the end wall to the longitudinal frame members of the car. Another object is to so form such an attaching means that it will constitute a very strong vertical beam to resist the horizontal load imposed thereon by the end wall, particularly by the horizontal reinforcing corrugations or embossments, if such are used in 3o the end wall.V c

Such a means of attachment,-or double gusset, will also perform the usual functions of t iecorner post or end frame member of the as it also has considerable column' car, strength. The end post forms a part of the side truss of the car which carries the load of the lading, therefore, my constructiony is desirable in a car end having the sheets secured together along vertical lines. 4@ In the drawings:

Fig. 1 shows a partial side elevation of a railwayk car with my invention applied thereon. Y

Fig. 2 is an end elevation of the same car.

F ig. 3 is a perspective view of the double gusset. f

End walls for railway cars now in general use comprise an upper (preferably corrugated) plate 2 overlapping and secu-red to a lower (preferably corrugatedj" plate 3 on a 1929. Serial N'o. 358,304.

substantially horizontal line 4. These plates are preferably provided with flanges 5-6 adjacent their vertical margins with the: viianges 5-Of they upper sheet overlapped and secured to the flanges ofA the lower sheet. These fiangesiare secured directly or indirectly to the side plate 7 and side sills 8, respectively, so ,thatk the end wall and' flanges perform the functionsof the usual corner post of the car.

The double gusset member 10 is attached to both the upper and lower endl wall'plates either' directly or through the medium of the upperV and lower vertical flanges f5 6 and is also secured to the side sill 8 andY side plate 7 or other longitudinal frame members of the car (11,). Thedrawings show bolts 12 and rivets 13, respectively, serving this purpose. Y

The gusset member is relatively narrow adjacent its middle part V(15) and relatively wider adjacent its end portions and is preferably provided with a flange 1G at its outer vertical margin which decreases in depthr from the middle part ofthe member toward its opposite ends, respectively. f

A lseries of corrugations 18 transfer an equally distributed load upon the member 1() which, with its double gusset construction, forms a pair of cantilevers to distribute `the load to the sill and plate,-respectively. If

t-he car is provided with intermediate belt L rails 11, part of the load would be distributed to these rails. The' outwardly projecting flange 16 stilfens the member as a beam and 'i as a column.

I have shown and described my construei L zontally corrugated or embossed end wall is "9' adaptable. y

The accompanying drawings illustrate the preferred form of the invention, though it is to be understood that the invention is` not limited to the exact details of construction lool gli; i i 1,770,691

I claim: 1. Means for attaching a horizontally corrugated end Wall of a railway car to the longitudinal frame members of t-he car comprising a double gusset which is relatively narrow adjacent its middle part and relatively wider adjacent its end portions, said member bein secured to said end wall and to said `lon 'tu inal frame members at its opposite 10 en y i n 2. Means for'attachmg a horizontall `corated end wall of a railway car to the origi-v tu Inal frame members of the car comprislng a. double gusset which is relatively narrow 15 ad'aoent its middle part and relatively wider adac'ent its end portions and provided with a' ange at one vertical margin thereof, said bei secured to said end wall at its other vertice margin and to said longitudinal fm frame members atitsopposite ends.

3. Means for attaching a-horizontally co1'- i'll tedend wall of a railway car to the longitu inal frame members of the car compris-` ing a double `gusset which isrelatively nar- *rowadjaoent its middle part and relatively wider adjacent its end portions and provided w'tlifa flange at one vertical margin thereof which decreases in depth from the middle partfofythe member toward its opposite ends,

'lo Baidf member being secured to said' endV wall at its other vertical margin and to said longitudinal frame members at its opposite ends.

4. In a railway car having upper and lower horizontal frame members, the combination *i6 of an end Wall comprising two metallic plates joined along a horizontal line and formed Ywith integral horizontal embossments terminating within the plate adjacent a vertical margin thereof, and a member having its n 'opposite ends secured to said frame members respectively with its inner vertical marginal portion secured to the vertical margin portions of said sheets, said member being relatively narrow adjacent the joint between said plates and increasing in width toward its opposite ends.
