the same, reference being had to the accom-' panying drawings, forming part of this specification.

My invention relates generally to railway car structure, and specifically to a form of metallic car end which is designed for use on box cars, either as a portion of the original car structure, or as a repair partwhich may be substituted in cars whose ends have been damaged.

The general purposes of my invention are, to provide a form of a car end structure which may be economically manufactured and repaired at little expense; which is strong and stable so as to effectively resist the various stresses to which such a part is sub ect, lncluding various blows and stresses imparted by shifting load, weaving influences, vertical stresses incident to supporting the roof, and all the other various stresses received by the end structure in service. 7 The accompanying drawings are illustrative of one form of my invention, Figure 1 being an elevation; Fig. 2 showing a vertical section taken approximately on line 22 of Fig. 1; and Fig. 3 a detail illustrating a front portion of a modified form. Fig. 4 is a detail of a side portion of same.

It has been customary in practice to form car ends of sheet metal sections which are joined at their edges, the joints between the sections sometimes running horizontally and sometimes vertically of the structure. Such end structures have been corrugated or ribbed in various fashions for the purpose of imparting additional stiffness and stability to the metal. One of'the serious considerations in such structures has been the provision of sufficient strength and stability at the joints Where the adjacent sections are riveted together, as such joints are usually disposed, as a matter of convenience in manufacture, at points Where they are likely to be subjected to severe stresses due to shifting load or other internal or external infinence. v

In the structure illustrated in the accompanying drawings, I have devised an end structure having the various sections or portions of metal of which it is composed so ribbed, arranged, and secured as to provide a maximum strength and stability at the joints, and a car end having great strength and stiffness for its weight. a

In the form illustrated, it will be see] that the end is made up of a first section 1,

a second section 2, and an intermediate section 3. The first and second sections are provided with suitable stiffening ribs or corrugations 4 which may run vertically as shown, or may be otherwise disposed so as to impart stiffness to the structure. Adjacent its lower edge, the first section 1 has pressed therein. a stiffening rib or corrugation 5 extending the entire length of the section and adapted to cooperate with the oppositely disposed frame members of the car to which the end structure is affixed. The margins 1 of the section may be suitably flanged to provide portions for attachment to the proper members of the car framing. The

portion of the section adjacent the stiffening corrugation 5 may be slightly offset to accommodate the upper portion 3 of the middle section 3. The middle section 3 is formed with a longitudinal corrugation or stiffening rib 6 disposed in proximity to one of its margins, leaving the portion 3 of sufficient extent to extend behind the corrugation 5 of the first section, to which first section the middle section 8 is attachedby rivets 7 or other suitable fastenings disposed at the inward side of the stiffening corrugation 5. When in position, the rib (3 of the middle section lies adjacent the mar gin of the first section, running substan- .tially parallel to the rib 5, and forming an ployed to secure the outer margin of the intern'icdiate section to the second section.

By virtue of this arrangement, it will be seen that I have a very rigid and stable reinforcing member formed by the lapped portions of the sections, the corrugations 5 and 6 cooperating with the underlying portions of the sections 3 and 2 to form box girders which extend continuously between the framing members of the car to which the sections are attached. Furthermore, I have the triple. thickness of metal disposed intermediate the corrugations 5 and 6. When the joints are horizontal, as illustrated, this arrangement provides a water-proof structure, inasmuch as all of the exterior joints open downwardly, thus effectively preventing the ingress of water and dust. The underlapping arrangement of the sections also gives the end structure a plain interior surface.

If desired, as illustrated in Fig. 3, the extremities of the section 3 may be extended to form the attaching flanges 10 by which the end may be securely tied into the car structure. If desired, the corrugation 6 may be extended around the corner to afford additional stability at the corners and to strengthen the flanges 10.

In the form illustrated, the arrangement provides a very strong girth member which extends across the end structure approximately at its median line, and is very effective in resisting stresses which would tend to distort or damage the end. It is obvious, however, that if desired, the joints may be disposed verticallv, in which case the stiffening member formed by the conjoined corrugated edges of the sections acts both as a central stlfiening member in the end structure and a roof supporting member. The corrugations 4 extending from adjacent the median stiffening member to adjacent margins of the sections which are attached to frame parts, operate to strengthen and stiffen the entire end structure and to transmit stresses received by its various parts to the median stiffening member and the frame members.

In practice, this end may be economically manufactured as comparatively small sheets are required to make the sections, and the structure may be readily and economically repaired, as a damaged section may be removed and replaced without necessitating the removal of undamaged sections.

I am aware that the structure is capable of various changes and modifications not herein illustrated and described, without departing from the spirit and scope of the invention.

What I claim is:

1. A car end composed of three conjoined.

sheet metal sections the form and arrangeedges of the third section.

3. A car end structure including three sheet metal sections overlapped seriatim and secured together, the exterior overlapped portions of said sections being corrugated to form substantially parallel strengthening members disposed adjacent a junction line of said sections.

4. In a car end, three sheet metal sections.

the middle one of which has a portion ex tending behind a corrugated portion of the section at one side thereof and a corrugated portion overlapping the section at the other side thereof, and fastening means securing each of the sections to both the others intermediate said corrugated portions.

5. In a car end, the combination of a first section of sheet metal formed with a corrugation extending longitudinally adjacent an edge thereof, an intermediate section hav ng a portion overlapping the said corrugation and secured to the first section at the inner side of said corrugation, said intermediate section being formed with a corrugation extending longitudinally adjacent the edge of the first section, and a third section having a portion overlapping the corrugated portion of the intermediate section and secured to said intermediate section at both sides of the corrugation therein.

6. In a car end, a plurality of conjoined sheet metal sections, each overlapped upon the others, said sections being shaped to form a plurality of substantially parallel box girder members extending along the joined edges of the sections.

7. In a car end, a plurality of sheet metal sections including an intermediate section secured to a section at one side thereof by a double line of fastenings and to a section at the other side, thereof by a double line of fastenings, the sections being corrugated between the lines of fastenings, and each overlapping both of the others.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses, this 17th day of I ebruary, 1915.
