Patented Nov. 9, 1948v 2,453,322 RAILWAY FREIGHT CAR CONSTRUCTION Albert E. Jaeckle, Laura] Park, N. Y. Application September 20, 1947, Serial No. 775,162

4 Claims. (Cl. 105-410) This invention relates to railway cars and more A particularly to the wall construction thereof especially at the vertical corners thereof. End walls of railway house cars are commonly madeof metallic plate having substantially horizontal parallel corrugations therein which function as beams between the corner posts of the car. Side walls of such railway cars also include side wall sheets which extend between corner posts of the car.

Recent trends in railway house car design have been toward ever increasing capacity and reduction in weight of the car, which, together with the increasing speeds at which trains are run, necessitates a proportionate increase in the strength of the car walls. Improvements in the design of corrugated end construction approach the ultimate in strength of corrugated plate of a given material and weight, and consequently if further strength is desired with the same material and weight, other factors must contribute toit.

Furthermore, due to said increase in speeds, and the consequent racking of the car, the car lining is apt to become loose, resulting in dust, dirt, grain etc getting in behind said lining, becomingrnoist from condensation or otherwise and increasing the rate of corrosion of the metallic car walls, as well as creating vermin-breeding places. M

It is the principal object of the invention to provide a house car corner construction which is of increased strength and which includes a strong corner post comprising a pair of spaced integrally formed Z-sections, one of which sections extends around a vertical edge of a car side wall lining and overlaps the adjacent vertical edge of the car end wall lining, which formation of the corner post in cooperation with the car lining provides an absolutely tight corner for said lining.

It is another object of the invention to form said corner post so that the end wall lining, which is subject to the greatest abuse during shifting of lading. Or at least the end board of said lining, may be readily removed for repair, replacement or to afford convenient access to the space between the end wall and lining for cleaning or other purposes.

A further object of the invention is to incorporate in my improved corner post structure means to attach a corrugated end wall sheet to said corner post so as to make the corrugations function as semi-restrained beams, instead of simple beams, thus increasing the strength of said corrugations as beams.

Other objects and advantages of the invention will appear in the following description thereof.

Referring now to the accompanying drawing forming part of this application- Figure 1 shows a typical end wall for a railway car embodying the invention.

Figure 2 is an enlarged cross-sectional view on line 2-2 of Figure 1.

In the drawing a common steel freight car end wall is indicated at I having substantially horizontal parallel major (2) and minor (2') corru gations formed therein which act as beams and carry any loads imposed thereon to the corner structure of the car. The vertical margins of the end wall are flanged, as at 9, on a curve of relatively large radius and the ends of the corrugations 2 and! terminate and merge into the said flange 9.

The improved corner structure comprises a vertical nailing post 3 positioned normal to the vertical plane of the side wall of the car. A vertical corner post member is indicated at 4 comprising preferably angularly disposed arms 5 and 8 provided with flanges 1 Flange 1 of the corner post is parallel with flange 9 of the end wall, and a vertical margin III of the side wall sheathing is interposed between said flanges 1, and 9 and the three securely united by a row of rivets, one of which is indicated at I I. The nailing post 3 and arm 5 are provided with a vertical row of registering holes through which any acceptable fastening means may extend, one of which is shown at l2, for securing said nailing post to said corner post 4. The inside side lining I3 is nailed or otherwise secured to the nailing post 3.

Flange 8 of the corner post is provided with a reflange l4 terminating in a. flange I5 which ex tends parallel with the general plane of the end wall, and said flange I5 is recessed into the adjacent vertical edge of the end wall lining is so that the inner face of the end lining and flange I 5 occur in the same plane. At the juncture of flange 8 and reflange M, the corner post is welded, as at 30, to the valleys of the corrugations 2 and 2'. It will be noted that arm 6, flange 8 and reflange ll completely surround the Vertical edge of side lining l3, and that refiange H and flange l5 overlap the adjacent vertical edge of end lining Hi. This structure of corner post and its described relation to the car lining provides a very tight corner and prevents any granular lading from getting in between the car liningand adjacent wall of the car. Of course, the corner post and 8 respectively.

-tion of material, integral with the' corner post,

inwardly from the true corner of the car, which adds considerable strength without a great deal of additional weight, over the conventional corner post structure.

Also it will be evident that this Z-shaped termination 8, i4 and IE oi the illustrated corner post structure may be integrally formed on the vertical edge of any acceptable corner post structure without departing from the spirit of the invention.

flange overlapping a vertical edge of said end wall lining, thereby providing a tight corner between said linings.

, 2. In a railway car having side wall and end wall linings, a corner structure comprising a corner post having an arm in surface contact with said side wall lining, a flange extending parallel In the illustrated structure the end board of v the end wall lining it is vertically disposed and of ship-lap construction and nailed or otherwise easily removably secured to the nailing filler strip 2| fitted within the corrugations o! the end wall for this purpose.

The accompanying ferred form of the invention, though it is to be drawings illustrate the preunderstood that the invention is not limited to,

the exact details of construction shown and described, as it is obvious that various modifications thereof, within the scope of the claims, will occur to persons skilled in the art.

I claim:

1. In a railway car having side wall and end wall linings, a corner structure comprising a corner post having a portion provided with a flange extending parallel with the plane of said end wall lining and a reflange overlapping a vertical edge of said side wall lining, said reflange provided with a flange extending parallel with said end wall lining, said reflange and last mentioned with the plane of said end wall lining and a refiange overlapping a vertical edge of said sidewall lining, said refiange provided with a flange extending parallel with said end wall lining, said reflange and last mentioned flange overlapping a vertical edge of said end wall lining, thereby providing a tight corner between said linings.

a 3. In a railway car having side wall and end wall linings, a corner structure, a corner post having an arm in surface contact with said side wall lining, and a Z-shaped section integrally formed with and continuing from said arm generally at right angles thereto, portions of said arm and Z-section overlapping a vertical edge oi said side wall lining and portions of said Z-section overlapping an adjacent edge of said end wall linin thereby providing a tight corner between said linings.

4. In a railway car having side wall and end wall linings, a corner structure, a corner post having an arm, and a Z-shaped section integrally formed with and continuing from said arm generally at right angles thereto, portions of said arm and Z-section overlapping a vertical edge of said side wall lining and portions of said Z-section overlapping an adjacent edge of said end wall lining, thereby providing a tight corner between said linings.
