, This inventionrelatesto railway cars and more I particularly railway freight cars with especial reference to box cars andv the like `and the primary purpose of the invention is the provision ofv a corner post construction aording greatly in.`

creased strength in the end wall structure of cars of this type. The invention, however, contemplates use of the construction as other than `a corner post, such for instance, as a door post and further` contemplates use of the poston other' than box cars. The invention also comprehends use of the construction as a general framing member.

The invention has for its principal object to provide a corner post adapted to be constructed in whole or box sectionform as a sub-assembly whic'lrmay be handled as a unit during the opera tion of fabricating the post into the lframing structure in association with other framing mem- .20

bers at the assembly locations.

An important object of the invention lies in the provision of a box section corner post consisting of an outer arcuate member having a com plemental inner angular member secured thereto in a manner to afford the box section and-inwhich the outer member extends beyondthe opposite attaching points of the inner member to providev anges for the attachment of the car end and sidewall sheathing.

ner pos'tconstructed of cornplementalinnerl andy outer members each having anges extending at right angles and secured together. in opposing relationto provide' a box section column with the anges of one member extending beyond theI respective flanges of lthe other member. l i

The corner lposts I8 are continuous members.l

The posts each comprise an inner member 26 having anges 21 and 28 disposed at right angles to each other and an outer member 29 having flanges 30 and 3l at right angles to each other. The inner and outer members complement each other and when secured together in opposed relation provide a hollow boxsection withlthe ilanges; ofLthefmember 25 securedl ec'lgewi'sev to theinner surface of the member 29 and the flanges of the latter mem ber extending beyond the attachment thereto of' the flanges of the first member whereby, to aiord a hollow column having flanges" projecting at right angles therefrom for theattachmentofend wall and side sheathing respectively;7 `Byfthcfse;

The inner member 2S might; be said to define the anges 30 and 3'If of' the outer member in thatV the former detere mines the limits of the hollow box section and' the iianges extend outwardly therefrom. The hollow. box section column is '0iAVV such. size as to provide a postr of: the necessary strength and is so proportioned as tov-spacel and supportA theinsidel liningin conformity with the remainingrpcsts offthe side Vframe (not shown). The-side lining 45 is disposed flush against the surface 'of the flange 21` of'inner 'member i8. and issecuredjto nailing strip tilwhichis attached to the'corner post. by means of.` bolts di. The-end of the side lining adjacentV the end wallis: disposed between the surface. 21." and: the abuttinglend lining 251 as bes'tshown in Fig..2: Tliebolts-Mare anchored' to the corner post by means of keyhole slots 40 which are disposed-v at. space'di intervals in` the flange 2S of the inner member and into which the 'bolts are inserted' as best illustrated in Figs. 2' and 4. Thek bollo-woon:4 section construction therefore is of the sam'edimension-as the-carsidey and framing and with the flanges 30 and 3|: ex'- tending therefrom, ideal means for attaching the cornerp'ost in thecar framing is provided. With the respective anges ofthe corner post thus s'ecured to the car end by means of rivets 46 and to the `side flange' 33 of the endk and the side sheathing I2 by means of rivets 48', it will beseen that the columnar post rigidly connected top and bottom to the roof framing and underframe pro- Vides an exceedingly strong reinforcement for the car end adapted' to-oifer the greatest resistance to impact andlto the various forces to which the end is subject'ed Byk the use of a unitary-:corner post,` all loads imposedon the car endv are transmitted to the corner post as a whole and individual 'part of the car framing and thence distributed to they car side and framinggenerally.

The'integijated box section characteristics of the corner post and the manner of securing the post strength for the conditions encountered at this location and stiffens the entire framing structure at'the ends. The rigidly connecterl'l flanges-,at right angles to each other; o n the comerjpost kaiord convenient means for secure attachment of the post in the corner formed by the side and end walls and the hollow box section construction effected by the association of the inner member 26 with the outer member 29 -1ends the utmost rigidity to the post in resistingthe torsional stresses created by the transmission of forces be-k tween the end and Sides.

It will be readily understood that many modifications in the construction of the cornerpost may 4be made. without departing from theinvention as disclosed herein. The post may take the form of opposed complemental angular members or any combination of opposed complemental angular and arcuate members or diagonal members opposed to either complemental arcuate or angular members. One form of slight modification of the corner post is illustrated in Figs. 3 and 7 in which the post is provided with corrugations at intervals corresponding to the corrugations in the car end. In Fig. 3, the horizontal section is takendirectly through one of the corrugations 22 at the corner of the end. From this figure it will be seen thata rib 50 is pressed in the outer arcuate member 29 transversely of the' post and extending continuously in a diagonal direction between the flanges 21 and 28 of the inner member. The rib 50 thus disposed in opposed relation to the corn'er corrugation 22 of the -car end and combined therewith provides a hollow tubular horizontal stiffeningbeam extending around the corner of the end in continuation of the various corrugations 2| of the end. The ribs 50, as will be observed from this ligure, are indented inwardly of the surface of' the outer member to the full depth available between the attachment points of the outer member to the inner and are disposed at vertically spaced intervals as shown in Fig. '7 which correspond to the corner corrugations 22. l

While the invention has been stressed herein for use as a vertical post member it is conceivable that theconstruction may be utilized as a 1ongitudinal framing member such for instance as a side plate or a side sill and sometimes as an end plate or sill disposed transversely of the car. will readilybe understood that a framing member constructed in accordance with the present disclosure is adaptable to use in any corner structure where it is Vdesired that the corner member have attaching anges at right angles and the increased strength of a box section, Whether it be as a vertical member or disposed horizontally and either longitudinally or transversely.

The foregoing is for the purpose of disclosure only and is not to be construed as limiting the invention in any way Aother than defined by the claims hereto appended.
