4 Claims.

l The invention relates to welded corner post construction for railway cars adapted for structural assembly with adjacent car wall portions. An object of the invention is to provide a stable connection between the end and side walls of a car to form with the end wall a complete box section post structure affording high torsional resistance in both directions.

Another object is to reinforce the box sectionv post structure throughout substantially the height of such post to prevent distortion thereof under thrust of the lading against the end wall of the car.

A further and important object isto provide a reinforcement for the post structure such as to afford securing and backup means for the horizontally extending side wall lining boards at the proximate position of the vertical lining,

boards at the end wall to insure grain-tight joints at meeting points. j

A still further object of the invention is to so correlate the attachmenty of the reinforcing means to the post and the post to the end wall by welding as to prevent eccentric loading of the weld metal and possible disruption of the asthe side wall boards at their ends and to supportv the nailing strip securing said boards; l

Fig. 2 is a vertical sectional view taken on line 2 2, of Fig. l, through the car sidewall adja-y cent the corner post assembly, showing attachment of the side wall board nailing Vstrip to the post angle reinforcement and the wall boards nailed to said strip;

Fig. 3 is an elevational side view of the car at the corner post position showing portions of the ange of the corrugated steel end wall broken away to expose the corner post structure on line 3-3, of Fig. l, and the method oi securing same to the side and end walls, preferably by arc welding to the steel end corrugations and by other means to the car side;

Fig. 4 is an elevational view of the outer side of the diagonal plate element of the post assembly showing attaching flange for securing the assembly members at the side wall position; and

Fig. 5 is atransverse elevational view of the same showing the side extending transversely of intervals between the side walls II.

2 the lcar with the nailing Stringer supporting ange of the reinforcing angle welded to the diagonal plate portion of the post assembly.

In said drawings, II) represents a railway box car having metal side Walls I I, corrugated metal end wall I 2 connecting the side walls, metallic roof I3, side plate and sill longitudinals I4 and I5, respectively, and transversely arranged end sill members I 6, and connecting side plates I4 and end wall I2 are the customary corner gusset plates I l, as best shown in Fig. 3.` The end Walls I2 are preferably corrugated as shown, with the corrugations I3 extending from side'to sideof the car and terminating in rounded corners I9` merging with the end wall securing flanges 20 taking rivets 2I at the side walls II. `Vertically disposed wood lining boards 22 are securedto the end wall by nailing them to furring timbers 23 nested Within corrugations I8 and held from displacement therein by collar bolts 24 at spaced Side lining boards 25, extending longitudinally of the car, are secured by nailing to upright wood post furrings 26 held to the car framing posts by collar bolts 2l, or the like, as best shown in Figs. 1

and 3. v

In the preferred embodiment of the invention herein disclosed, the sidey and end wall lining boards at their meeting points are held in graintight relationship by structure, presently to be described, designed to prevent disruption of the joint by restraining torsiona] movement of the corner post assembly functioning to stabilize the framing under car and lading impacts. In the corner post assembly structure of the present embodiment as depicted in Fig. 3, the diagonal plate member 30 is connected to the steel end wall I2 by arc welds 3l at the corrugations o f the end in the vicinity of the joint 32 between the side and end lining boards 25 and 22, respectively, tol

prevent bulging of the end from top to bottom at that position. A rigidifying angle memberA 33 extending Athe full height of the plate andhaving a flange 28 disposed parallel to the side wall boards 25 is adapted to back up the boards at the joint 32r to insure Contact with end wall boards 22, and a companion ilange 29, extending outplate member 30 together form a hollow weldedy wardly from and normal to complemental flange 28, functions to support the nailing post furring strip 26 to which the side wall lining boards 25 are secured. Said reinforcing angle member 33 is secured to the diagonal plate member 30 by column 39 adapted for assembly with the corrugated end wall portion I9 through the medium of arc welds 3l to provide a prefabricated unitary structure designed for assembly with the car side walls l l preferably by rivets 2i connecting the end wall flange 2i) and the diagonal plate and stiiiener angle unit through flange 36 on the diagonal plate portion of said unit, as best shown in Figs. 1, 2 and 3. The diagonal plate and reinforcing angle unit provides the connecting element for the whole corner structure. The diagF onal plate portion 30, secured at one of its edges to the side wall through ilange 36 by rivets 2l and by arc welds 3| to the end wall at its opposite edge, is subjected to tension in its function to prevent distortion of that portion of the end wall represented by the arch I9 between said welds and rivets to preserve the rounded corner of the corrugated end wall l2 to provide in effect a hollow column 4B extending from the side plate I4 of the car to the bottom at floor 9. The colf umn 4,0 thus created operates to supplement the hollow column 39 formed hy the welding of the flanges of the stiffening angle 33 to the diagonal plate member 30, the two column members together providing a structurally stable corner to maintain the rectangular relationship between the side and end wall lining boards at the joint 32. With the ar-c welds 3|, 34 and 35, disposed.

as they are at the edges of diagonal plate and flanges 28 and 29, and in line with lstresses imposed parallel to said plate and flanges, eccentric loading of the welds is avoided to insure complete integrity cf this unit. Proximity of the welds to the juncture of plate 30 and its securing flange 35, lessens the possibility of distortion of this member under excessive stressing of the framework at the cor-ners of the car and resultant bulging of the end wall from car impact and lading thrusts. As in common practice, bolts of the collar type 24 and 2l are used to secure the side and end wall furring pieces 26 and 29 to support the respective lining boards. For removably mountingv the side furrings 26, the flange 29 of reinforcing angle 33 is provided with a plurality of contracted openings 38 to receive the bolt heads, shown best in Figs. 1, 2 and 5.

From the foregoing it will be noted that a corner structure has been provided having a high torsional resistance in proportion to its weight, since the` welding together of the elements comprisms the. assembly ci parts disposed in there" latonship stated develops. the. full strength. of the material used. The construction permits the,

prefabrication of the end wall and corner strucf ture as, 2 unitary Whole and is made possible by the` fabrication or" the hollow column member 3,9. as a sub-.assembly and its` subsequent attachment, to the end Wall l2 by, welds. 3i. The welds; 3 1 are, gnlciently rugged to hold the hollow column unit 39,111 desired relationship. with the end wall such that the danses ze of the end and danses a6 or the unitary members 39 will be held spaced apart adi-'nit side wall sheath-ing plates. tl between them when th end is mounted position upon the. car for assembly with the c ar sides and riveted, as best shown in Figs. l and 3.
