, OF'ST. LOUIS, MISSOURI, A CORPORATION OF DELAWARE GRAB IRON 0R LADDER Rune- Application filed March 5,

This invention relates to grab irons and ladders of the kind that are used on freight cars. I I

The main object of my inventionis to pro- Vide a grab iron or ladder rung for freight cars that is exceptionally strong and rigid, light in weight and inexpensive to manufacture. r p Another object is to provide a sheet metal grab iron or ladder rung of the character above described, that 'has integral portions for attaching it to a supporting structure. I

Figure 1 is a fragmentary elevational view or ladder rungs constructed. in accordance with my invention.

Figure 2 is a top plan view of one of said grab irons. I f

Figure 3 is a side elevational view of said gralb iron, looking at the inner side ofsame; an 7 Figure 4 is an end elevational view of said grab iron. I In the accompanying drawingswhich illustrate the preferred form of my invention, A designates one wall of a freight car body and B designates grab irons or ladder rungs that are attached to said wall. Said grab irons or ladder rungs are formed from sheet metal and each one of said members comprises a substantially tubular, bar-like portion 1 provided at its opposite ends with integral devices that perform thedual function of spac ing devices and attachingdevices. In the preferred form of my invention, as herein i1 lustrated, the combined spacing and attaching devices just referred toconsist of substantially L-shaped members whose legs 2 are disposed at substantially right angles to the tubular, bar-like portion 1 and whose legs 3 are disposed'in substantially parallel relationship to said tubular, bar-like portion 1. The legs 3 are adapted to bear against the wall A of the car body and are provided with holes 3 for receiving fastening devices 3' that penetrate into or project through the wall of the car body. I

At the ends of the bar-like portion 1 of my improved grab iron or ladder rung are inclined end walls 4; that form in effect closures which carries it.

5 on the end walls of the tubular, bar-like portion 1.

A grab iron or ladder rung of the'design by a die-shaping or pressing operation. It is ofless weight and of less cross-sectional area than a grab iron or ladder rung formed from a solid bar, but nevertheless, it is stronger and more rigid than the conventional solid grab irons and ladder rungs now used on freightjcars. While I have herein illustrated my invention, embodied in a grab iron or ladder rung that is provided with inl' tegral portions which are used to hold it in spaced relation and also to connect it directly to the carbody on which it is used, I wish it to'be understood that it is immaterial, so far as my broad idea is concerned, what means so or method is used to attachsaid grab iron orladder rungto the supporting structure Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: I

1. A grab iron orv ladder rung for freight 7 cars, consisting of a pressed metal member. having a substantially tubular, bar-like portion whose ends are closed by inclined end walls that merge into spacing devices which are disposed at-substantiallyright angles to said bar-like portion, and laterally-projecting flanges on said spacing devices.

2. A grab iron or ladder rung for freight cars formed from a flat plate orstrip of metal that is pressed or die-shaped so as to produce a bar-like member of substantially tubular sitely-inclined end walls, substantially L- shaped devices integrally connected with said end Walls for attaching the rung t0 the car and holding the bar-like member of same spaced away from the car, and pressed reinforcing ribs in said end walls and L-shaped devices.
