3 Claims.

the tunnel clearance line established by the Asv /sociation of American Railroads.

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, and wherein like reference characters indicate like parts:

Fig. 1 is a plan View of a portion of a car roof embodying my invention.

Fig. 2 is a section on the line 2 2 of Fig. l.

Fig. 3 is a section on line 3-3 of Fig. 2.

In the drawing:

The numeral I indicates one of the side posts of a car, which posts are of plate material bent in the form of a U-shaped member and` having laterally extending base flanges 2 and the upper ends of these side posts are slightly inwardly and upwardly curved or defiected, as at 3. The side plate of the car is illustrated as comprising a substantially W-shaped member formed of sheet material and having a horizontal arm 5 resting upon the tops of the side posts. Along the outer edges of the arm 5 the side plate is formed with a flange 6 which extends downwardly and outwardly, conforming to the deflection of the upper ends of the side posts, and said flange is secured to the outer edges of said side posts by plugwelding, as indicated at I. At the inner edge of the arm 5 there is provided an upstanding substantially vertical arm 8, the upper margin of which is turned inwardly and slightly upwardly, as at 9, to follow the plane of the roof sheets Il). The outer margins of the roof sheets bear directlyl upon the ange 9 and are turned thereover, as indicated in Fig. 2, to bear flatwise against the arm 8 to which they are secured by welding or other suitable means. Y

The side sheathing of the car is indicated at I I, and is formed of flat sheets each of which extends between adjacent posts I, secured to the lateral flanges 2, exteriorly thereof and may be Vwelded along its upper edge, as at I3, to the side plate at the juncture of the

arms

5 and 8, thereby providing a weather-tight union of side plate and sheathing. The inside lining of the car is shown at I2, it being attached to the side posts, as is common, and the inside surface of which is substantially in the plane of the inside surface of the arm 8 so that lading may be carried within the car right up to the roof thereof.

It will be noted, too, that the outer lower edge of the flange 6 of the side plate is in the same Vertical plane as the outer surface of the side posts I, In order to obtain the maximum inside width I4 of car, the outer surface I5 of the side post is placed the maximum distance apart permissible by the interchange rules of the Association of American Railroads. Thus with my present construction the width of the side plate material is saved, or in other words, the car may be twice the width of the side plate material wider, which means, of course, that the lading space for the full length of the car is that much greater.

Also, because the upper ends of the side posts are inwardly turned, the roof is narrower than ordinary and yet the car is a little wider than ordinary. Consequently the roof is lighter and less expensive.

It, therefore, follows that the construction has advantages over the ordinary type of railway freight car construction by making it possible to provide a higher and a wider car than otherwise possible, with a narrower roof, and yet provide a larger lading space.

The accompanying drawing illustrates the preferred form of the invention, though it is to be understood 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

I claim:

1. In railway freight car construction, side posts, the upper ends of which are inwardly deflected, a lining positioned inside of said posts below the deflected portions thereof, a side plate having a flange depending at the same deflection as the upper ends of said posts and within the outer vertical planes thereof, and a substantially vertical arm substantially in the vertical plane of the inner upper end of the deflected portions4 of said posts. a

2. In railway freight car construction, side posts, the upper ends of which are inwardly deected, a lining positioned inside of said posts below the deflected portions thereof, a side plate having a horizontal arm above the deflected portions of said, posts, and a substantially vertical arm substantially in the vertical plane of the insideV of said lining.

3. In railway freight car construction, side posts, the upper ends of which are inwardly deected, a lining positioned inside of said posts below the deected portions thereof, a side plate having a horizontal arm above the deflected portions of said posts, a flange depending at the same deeotion as the upper ends of said posts and Within the outer vertical planes thereof, and a substantially vertical arm substantially in the Vertical plane of the inside of said lining.
