My invention relates generally t`o railway cars and more particularly to af pressed metal structure, which forms the end wall of a car.

In railway cars, and particularly those designed for and used in the transportation of freight, the end portions of. the car body and the end walls are subjected to strains and stresses resulting from service shocks and vibrations and also by reason of thesudden starting and stopping of the cars and the shifting of the load and contents of the cars While the latter yare in transit.

One of the principal objects of my invention 4is to construct a car end from a plurality of sections `of material, preferably sheet metal, either plain orhcorrugated, said sections being practically duplicates and arranged so thaty the joint between the sections is horizontally disposed and in a plane approximately midway between the top and bottom of the end.

A further object of my invention is to combine with the meeting edges of the two sections of which the end is formed, one or more joint members, preferably commer` cially rolled metal shapes, thereby providing a comparatively simple, inexpensive car end vwhich can be readily combined With an ordinary car underframe and superstructure, and which end by virtue 'of its transversely disposed reinforcement and its pressed ribs or corrugations will be very effective in re` sisting such strains and stresses as may result from shifting loads, ordinary service shocks and vibrations or collisions.

A further object of my invention is to construct a car end having a trussed reinforcement which extends transversely of said end, preferably at a point midway between its upper and lower edges, and which trussed reinforcement combines with the meeting edges of` the sections to form a Water and dust proof joint, and at the same time providing a car end having a perfectly smooth inner face.

In order to comply with the Government regulations relating to cars utilized for transportation of explosives, it is necessary to provide car ends which are entirely devoidof projections, such as rivet or bolt heads, on their interior faces, for, if such 4construction were employed, it would be possible for a box or package of explosives when shifted suddenly within the carto strike against the projecting head of a bolt or rivet, and thus develop sufiicient impact to set ott or eiiect a discharge of the ex plosives. Likewise itwould be possible for a bolt or rivet when subjected to a blow from the exterior of the car to perform the functions of a hammer and transmit to a box or package of explosives positioned a gainstthe inner face of the cared, sufficient impact to effect a discharge of said explosives. K

Yith this consideration in view, it is one of the objects of my invention to construct a ear end having a, substantially smooth flat inner face, which end is made up of two or more panels, the meeting edges of which Patented Dec. 19, 1916.

are joined in such a manner as that the rivets or bolts utilized in fastening the edges together are positioned so that it will be impossible for said rivets or bolts to transmit percussive blows to boxes or packages of explosives located immediately against the inner face of the car end. A

'ith the foregoing and other objects in view. my invention consists in certain novel features of construction and arrangement of parts, hereinafter more fully described and claimed.

The car end illustrated in the accompanying drawings is made up of two sections or panels 10 and 11. the Sallie being substantiall) duplicates and for this reason. it is possible to produce both sections or panels from one set of dies. The lower edge of the lower panel 10 is attached in any suitable manner to the underframe of a car. preferably the end sill thereof. and the side edges of said lower section are bent rearwardly as designated by 1:2, to form flanges which are adapted to be attached to parts of the superstructure, preferably the corner posts. The upper edges of the lower section 10 are bent outwardly into 'a horizontal plane so as to provide an attaching flange 13 which conibines with a reinforcing joint member hereinafter described.

The body of the. section 10 is preferably provided with a series of vertically disposed outwardly pressed ribs or corrugations 14, the ends of whicl1.terniinate at or near the upper and lower edges of said lower section. These ribs or corrugations can be of the same width and depth throughout their length. or. if desired, they may gradually taper or decrease in width and length toward their ends The upper edge of the upper section 11 is adapted to be attached in any suitable manner to the upper portion of the car body, preferablyr the roof structure. and the sides of said upper section are bent rearwardly as designated by 15 for attachment to the corner osts. The body of the upper section 11 is provided with a series of vertically disposed outwardly pressed ribs or corrugations 16 which are counterparts of the.4

ribs or corrugations 11. The lower edge of the upper section 11 is bent outwardly into a horizontal plane to form a. flange 1T which lies immediately over the flange 13 on the upper edge of the lower section and interposed between these flanges 13 and 1T is the horizontally disposed leg of a commercially rolled T-bar 18. i

'Attaching means preferably in the form of rivets 19 are seated in the flanges 13 and 1T and the interposed leg of the bar 18. The flanges 1S" of the bar 18. which occupy a vertical plane. are positioned directly against the inner faces of the sections 10 and 11, and these sections immediately adn jacent to the flanges 13 and 17 are bent outwardly or offset as designated by 19*l in order to accommodate the flanges 18, and thus the exposed faces of said flanges occupy the same vert-ical plane with the inner faces of the sections 10 and 11.

In constructing or shaping the upper section 11, the flange 1T is made slightly wider than the flange 13, and this permits the outer edge of said flange 1T to be turned downwardly as'designated by 20 to form a. protecting flan which overlies the outer end of the bar 18 and the outer end of flange 13. Such construction not only assists ihn the reinforcement and stiflening of the end, but forms a waterand dust shed for the joint between the members 10and 11, from which the end is formed.

In the construction illustrated in Fig. 5 the flanges 13 and 17 are of equal width and the horizontally disposed leg or web of the T-bar 18 extends beyond the outer ends of said flanges and is bent downward to form a depending flange 20 which performs the same functions as the depending flange 20.

To provide the central portion of the car end with a trussed structure, the flanges 13 'and 17 vare widened, particularly at their mercially rolled member 21, such as an.

angle` Rivets or like fastening devices are seated in the outer vportions of the flanges 13 and 17 and the interposed leg or flange of the angle, and the outer leg or flange of said angle depends as shown in Fig. 7, thereby materially reinforcing-or stiffening the trussed structure and at the same time forming a water and dust shed. The oentral portion of -the angle 21 is bowed outwardly so as to be spaced apart' from the central portion of thel T-bar in this structure. and thus the members 18 and 21 perform the functions of trussing ele-ments with the flanges 13 and 1T serving as struts between said elements.

In the construction illustrated in Figs. 8 and 9. the web of a. commercially rolled Z-bar :22 is positioned between and rivetedl to the flanges 13 and 17, with the flan on the inner end of l'said Z-bar vertica y disposed and positioned against the lower edge of the upper section 11. The flange on the outer edge, of said .Z-bar extends downward to assist in stifening the trued structure and to also serve as a. water and dust shed. The web of this Z-bar is split length'- wise as shown in Fig. 8, and the outer portion of said split bar is spaced apart from the inner portion. thereby forming tension and compression members of a truss and with the. flanges 13 and 17 performing the functions Aof a strut.

By bending the meeting edges of the sections 10 and 11 outwardly and combining therewith a. joint member which is, in some t instances, a trussed structure, a transversely disposed reinforcing and strengthening member is provided which, in conjunction with the vertically disposed ribs or corrugationspressed outwardly from the bodies of the sections or panels, materially reinforces and strengthens the entire car end, and as a result, all internally or externally applied shocks or blows and all Iservice. strains and vibrations will be transmitted directly to the car underframe and superstructure.

The inner face of the car end is perfectly flat and devoid of projections, and therefore, cars equipped with my improved ends are particularly adapted for service in the transportation of explosives..

It will be readily understood that minor changes in tlie size. form and construction of the various parts of my improved car end can be made and substituted for those herein shown and described, without departing from t-lie spirit of my invention, the scope of which is set forth in the appended claims.
