Application filed November 6, 1313. Serial No. 799,516.

To all 'whom t may concern:

c Be it known that I, JAMESv J. COOPER, a citizen of the United States, residing in the city of St. Louis, Stateof Missouri, have invented a certain new and useful Improvement in Railway-Car Ends,of which the following is a full, clear, and exact description, such as will enableothers skilled in the art to which it appertains to make'and use the same, reference being had to the accompanying drawings, forming part of this specification, Iin which Figure l is an elevational view lof a car end of my improved construction. Fig. 2 is a side elevational view of a car end of my improved construction, the same applied to a car. Fig. 3 is a vertical section taken approximately on the line 3 3 of Fig. 1.

-Fig. 4 is an end elevational view of a modified form of my improved car end. Fig. 5 is a side elevational View of the end portion of a car which is equipped with the modified form of end. Fig. 6 is an enlarged detail sectional view taken approximately on the line 6 6 of Fig. 1 and showing the construction of the joint between two of the sections of my improved car end. Fig. 7 is an enlarged detail section taken approximatelyon the line 7-7 of Fig. l, and showing a preferred form of the means employed for attaching the car end tothe uprights or posts of the car frame.

My invention relates generally to railway ca'rs and ,more particularly to the construction ofthe car end walls.

` In railway cars and particularly those designed for, and used in freight service, the

end portions of the car body and theend walls, are subjected to severe stresses?v and strains resulting from service shocks and vibrations and by reason of thesudden starting and stopping of the cars and the shifting of the lading or contents thereof.

The principal object of my invention is to construct a car end wall from a plurality of sections of material, ,preferably sheet metal, each sectionbeing reinforcedand` stiffened, if desired, by ribs or oorrugations which are pressed in the sheet metal, and to provide on the car end wall so formed, one or more hollow reinforcing and stlffening members having certain characteristics. These reinforcing and stilfening members are formed at the joints between the sections effective in resisting such stresses as may arise from shifting loads, ordinary service shocks and vibrations or collisions.

lith the above and other objects in view, my invention consists in certain novel features-of construction and arrangement of parts, hereinafter more fullydescribed and claimed.

As illustrated in the accompanying drawingsand particularly Figs. 1, 2, and 3, the car end is composed of a pair of sheet metal plates or sections l and 2, each of which is formed with a series of vertically disposed stiifening ribs or corrugations 3. These ribs or corrugations are preferably arranged parallel with each other and are formed in the sheets of metal in any suitable manner, preferably by means of dies. The ends of the sections l and 2 are bent at right angles to the plane occupied by the main body portions of said sections as designated by et, and said bent ends are attached in any suitable manner to the end portions of the side walls of the car. The upper edge of the upper section lr is preferably attached directly to the top plate of the car end structure and the bottom portion of the lower section 2 is attached in any suitablemanner to the end sill of the car underframe. The lower portion of the uppeisection l overlies the upperA portion of the lower section 2, and this overlying lower portion is bent outward and downward as designated by Arranged between the lower edge of the outwardly and downwardly bent portion 5 and the adjacent portion of the lower plate 2. is a transversely disposed rail or bar (5, preferably a rolled shape such as a Z-bar. and where such shape is used, the upwardly projecting flange is attached in any suitable `manner to the lower edge of the portion fand the 1 depending lflange, is attached directly to, the upper portlon of the plate 2.

ately vabove-the outwardly and downwardlyjy bentportions, and thus said. portion 5', the' ijfoint memberf and thatportionofthe secbn 2 immediately behind said portions 5- afnd 6, form Aa-horizontally"disposed transk`ver ely;extending` tubular member or box `whichfinaterially strengthens and re a inforces the central portion of the end wall. 'fThevfdisposal-jofthe edge of the joint member-ebetweenthe overlapped edges of the -sections''preven'tsthe' entrance of water behindv 4t-he joint member, and protects the f-.jpintniem'ber from'v *possible blows which would tend tear it loose from the plates.

It begunderstood that a piece of sheet me'talbentftoproper shape may be utilized in place)-4 'the'l rolled shaped and also that .a shape Iother than a Z-bar can be utilized -asthe joint inemberpbetween the main secllizionsvfthe car end.

In Figs. -4 and'5 I have shown a car end formed ofi three main sections or sheets of '-{meta'lcfand' where such construction 1s em- '1f-'e0 :ployerL' a pair of box llgirders or tubular stiieing and reinforcing ,members are formed at the joints between the sheets of sectionsof'metal..

lv"The sides of -my improved car end are tied to thewtransom posts of the car body by' means "obolts 8, the inner ends of which arexed in an suitable manner to the tran- 'somf' s; e outer ends of these bolts extendfthrough the end portions of the and 2 and receive nuts, or like fasteningdevices. (See Fig.I 7). In case the platesgfdorining the'end wall are joined on ,vertical-instead of horizontal edges, it is obvious'that-,this structure will provide vertical stifenn members extending longitudinally fof-thep ates.

f- -Acarend of my improved, construction is comparatively simple, lcan be easily and cheaplyjmanu'factured, and by overlapping e fregi,riff-the sections of material of which end is formed, and arranging betweeijsaid edges a suitable joint member, a reihorcing member .in the form of a box IA ird'er is provided, which materially reinorces and v strengthens the car end and causes. all, internally and externally applied 'shocks and blows and all service strains and :wibrations Lito be transmitted directly to ra'rniiigfportionsjd the car body'or underinarnestrncture. 'fdt libe readily understood that minor l changes .1n the size, form and construction .hf'tlie-fvaiious' parts of my improved car end lmay begniadefr and substituted for those hereinV 'shown and described, without departing from the spirit of my invention, the scope .of which is set'forth in the appended claims.

I claim: f

1. A car end comprising a plurality of i sections` of sheet metal, the lower edge of one of which sections overlaps the upper edge of the adjacent section, and a joint member interposed between the overlapping ledges of said sections, portions of which overlapping portions combine with said `joint member to form a transversely disposed box girder.

2. In av car end, a' pair of sections of 'sheet metal arranged so that the edge of one section overlaps the edge of the other section, and a joint member having a portion interposed and secured between said overlapping edges, a portion of which joint member cooperates with portions of the sections to form a transversely disposed box girder.

3. In a carA end, a pair of conjoined sectionsoi:l sheet metal the upper one of which has its lower edge odset with respect to the lower section and overlapping said lower section on the exterior thereof, and a joint member extending longitudinally of the sections and having its upper edge disposed behind the offset edge of the upper section andsecur'ed thereto', and its lower edge secured to the lower section below the upper section, said joint member having portions disposed in front of the plane of said sections so as to form a beam for stiiz'ening the end structure.

4. The combination in a car end, of two corrugated plates, one located above another; a downwardly extending flange at the lower edge of the upper plate and an u wardly extending iange at the u per e ge of the lower plate, the flange o the lower plate being out of line with the flange of the upper plate; and a Z-beam, the up- .per flange of the'Z-beam being connected to the iange at the lower edge of the upper plate and the lower ange of the Z-beam being connected to the {iange at the upper edge of the lower plate.

5. The combination in a car end of two sheet metal wall sections one located above the other, the upper section having a lower marginal iange overlapping and offset from the upper margin of the lower section, and

ing flange at its upper edge disposed out of line with the flange of the upper section, and` a stiffening membervhaving a longitudinally extending upper flange connected to the flange of the upper section and a second longitudinally extending flange connected to the ange of the lower section.

In testimony whereof I hereunto aix my signature in the presence of two witnesses, this third day of November, 1913.
