To all'whom it may concern;

Be it known that I, WALTER P. MURPHY, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented ce1'- tain new and useful Improvements in Metal End Structures for Railway Cars, of which the following is a specification.

My invention relates to end structures for railwafy cars and has for its object to provide a rein orced sheet metal end structure which may be made relatively light in weight without sacrificing the strength and rigidity required in constructions of this character to resist the strains due to shifting of the cargo and otherv causes. y

When loading a railway car the heavier parts of the cargo are usually placed in the bottom of the car. In the event of lany shifting of the cargo, such `for example, as is caused by the sudden starting or stopping of the car, the lower part of the car end is subjected to greater strains than the upper portion. One of the specific objects of this invention is to provide a novel and inexpensive reinforcing means for a corrugated sheet metal car end structure whereby the structure will be strongest at thepoints where strength is most needed to resist the severe shocks and strains to which acar end is subjected while in service.l y

The invention is illustrated in the accompanying drawing, wherein:

Fig. 1 is an4 end view, in elevation, of a sheet metal car end structure constructed in accordance with the invention;

Fig. 2 is a vertical sectional view taken on line 2--2 of Fig. 1; i

Fig. 3 is a fragmentary sectional viewv taken on line 3-3 of Fig. l;

Fig. 4 is an end view in elevation of a railway car illustrating a modified form of end structure;

Fig. 5 is a vertical section taken on line 5 5 of the structure shown in Fig. 41; and

Fig. 6 is a sectional view, taken on the line ve-e of` Fig. e.

Like characters of reference indicate like parts in the several figures of the drawings. Referring to Figs. 1 to 3 inclusive o f the drawing, the structuretherein shown consists of an upper end sheet 25 formed with Aliorizontaatlly disposed contiguous ribs or corrugations 26 which extend from side to side of the sheet, and lower sheet 27 similarly corrugated, and side attaching members 28 which are formed with corrugations 29 adapted to fit over the extremities of the corrugations 26 and provided, preferably, with angularly disposed flanges 30 which overlap the side sheathing 31 of the car and are se cured to the body by means of bolts 32, for example, which pass through the corner posts 33. The upper sheet is preferably formed with a flat upper margin 34 which is secured by bolts 35 to the end plate 36 of the car. The lower sheet is preferably formed at the bottom with an inturned flange 37 which extends under the flooring of the car and is secured by means of bolts 38 to the end sill 39. rlhe upper sheet overlaps the lower sheet and is secured thereto by rivets 40. The corrugations of the side or attaching members 28 fit closely over the corruthe corrugations to the edges of the sheetl permits the sheet to be rolled instead of pressed and thereby cheapens the manufacture of the end structure, though it will be obvious that the reinforcing means for the lower part of the car, as will be hereinafter described, may be'applied equally well to an end sheet in which the corrugations terminate within the edges of the sheet. The side members 28 because of their configuration, have considerable load bearing strength so that they may serve as load bearing elements. In this or analogous constructions in which the attachin'gangles are separate from the end sheets, it is not necessary to'make the end sheets conform in width exactly to the width of the car. Any slight variation in the width of diderent cars will be taken care of bythe overlap of the attaching angles on the end sheets. If thick enough metalV is used the wooden corner posts may be disensed with or used simply as nailing strips. In order to reinforce the lower portion of the end so as to withstand strains incident to the shifting of the cargo and other causes, I have preferably shown a sheet metal lining 42 which is preferably riveted to each inwardly projecting corrugation of the lower sheet'27 by rivets 43. The sheet metal lining 42 being secured to the lower end sheet 27 in this manner provides a series of box' girders 44 which extend from side to side of the car so as to strengthen and rigidify the end structure at the lower part of the car. The sheet metal lining in the construction shown in the drawing extends only part way up the end, though it will be obvious that the said lining may be extended higher up than that illustrated without departing from the invention.

In Figs. 4, 5 and 6, I have shown a modified construction in which the

end sheets

45, 46, project beyond the sides of the car. These are formed with horizontal corrugations 47 which extend to the edges of the sheet, and are secured to the sides of the car by angular attaching members 48 which are formed with corrugations 49 adapted to fit the corrugations 47 of the sheet. The corrugated portions of the attaching member are preferably riveted to the sheet by rivets 50 and are secured to the car by means of bolts 51 which extend through the corner posts 52 of the car.

In these figures I have shown a metal lining 53 which in addition to closing the corrugations in the end sheet and reinforcing the same, as described in connection with Figs. 1 to 3 inclusive, also provides a cross brace between the corner posts 52 of the car. This sheet metal lining is riveted, as indicated at 54, to the inwardly projecting corrugations of the end sheet in substantially the same manner as described in connection with Figs. 1 to 3, inclusive, and is provided along its vertical edges with angular ianges 55 which preferably extend between the lining boards 56 and corner` posts 52 of the car. These flanges 'are secured to the end posts by means of the bolts 51. Y v
