CAR CONSTRUCTION.

Specification of Letters Patent.

Patented July l, 1919.

Application led May 21, 1318.1 Serial No. 235,763.

` vania,) have invented certain new and uses ful Improvements in Car Construction; and l do hereby vdeclare the following to be ,a full, clear, and exact description of the invention, such as'will enable others skilled in the art to which it appertains to make and use` the same. y

My invention relates to the construction of metal cars and has particular reference to stiffening members applied to the sides or ends thereof, to the margins of the plates, or other portions composing the inclosure, and is applicable to stiffening and strengthening the sides or ends of gondola, hopper, box yor other types of cars.

. reason of ltheir deformation.

. tortions.

My invention in general consists in apply-i ing preferably to the margins or other ortions of the car sides or ends, flanged sec-tions of particular forms which are adapted to strengthen or stiffen the structure and, at the same time, resist the impact of the lading such as lumps of coal, ore, limestone or other materials, when they drop or impinge upon the upper edges of the carvwhen it is being loaded. Other car stiffening constructions have generally been constructed so that they are only useful4 structurally as a chord or strengthening member without due regard to the deformation caused by the impacts above referred to and, in consequence, such members have become distorted and, in a measure, useless for the purposes. intended by All of this is obviated by my construction which pro= vides ample thick portions of shapes adapted to serve both as a stiffener and to resist dis- Having thus given a general description of my invention, I will now, in order to make the matter more clear, refer to the annexed sheet of drawings forming part of this specification andin which like characters refer to like parts.

Figure 1 is a fragmentary side elevation of a portion of a metal Vcar showing my top guard member in position; y.

Fig. 2 is a vertical cross sectional elevation on theline II-II of Fig. 1, but drawnv on a larger scale for the sake of clearness;

Fig. Sis a horizontal sectional plan on the line I II-III of Fig. 2 looking upward in the direction of thc arrows; and

F1g. 4: is a vertical cross sectional elevation similar to Fig. 2, but showing a modi-V `case my stiffening or top guard member acts as the top chord in addition to protecting the upper edge from deformation, as described. 2 is my stiffening member or flanged top guard member in general, 3 is an upper additional or laterally extendin flange, 4 is one. of the upper flanges, 5 1s one of the web portions which is shown as inclined at an angle somewhat greater than a right 'anglo to the flange. portionand of thickness greater near the flange fl than at its outer end, 6 is the joining flange which is shown as compartively thick and formed integrally with and uniting the webs 5 and 7; 7 is another web which is arranged generally at right angles with the flanges 4 and 8 and may be thicker at its outer edge thanl at the portion adjacent to the lower flange 8, but this is somewhat immaterial, 8 is the lower flange formed tapering, that is thinner at its outer edge, 9 are the side stakes of the car formed of trough shape with lateral flanges and thickened apex, as illustrated, these be-v ing shaped at their upper ends to conform to the contour of the top guard member and to fit snugly against same so that these portions function together properly, 10 is the bottom member of the car side which, in this case, is shown as an ordinary rolled angle with one of its legs secured to the inner side of the car plate and its other leg extending outwardly, the lower ends of the stakes abutting the same.

Referring now to Fig. 4,11 indicates a slightly modified form of my top guard member in general, provided with a oomparatively` small upper laterally extending flange 12, which is adapted to extend inwardly over the top of the car side and t0 form a closure and finish for same, 13 is one of the flanges of my top guard member, 14 and 16 are the web portions thereof, both of which are formed` sloping or inclined more than a right angle to the flanges, 15 is -the joining flange which is shown compara tively thick and formed integral with the webs 14 and 16, as illustrated. 17 is the lower flange which is shown as tapered and secured to the car side.

It will be seen that my top guard member is formed essentially of a trough or channel section provided with flanges laterally extending from the margins of the webs and one of these flanges has an additional lateral flange extending substantially at right angles therefrom, and my top guard section is secured to the car side by rivets passing through said flanges, and in cases where the stakes occur,` rivets also pass through the stakes securing the-three adjacent portions together. The stiflening members illustrated, form very substantial top guards which are well adapted to withstand the stresses and impacts of the lading to which they are subjected in use and, by reason of the angular arrangement of the parts and the thickness of the taperedflanges, they are well adapted to withstand the shocks or imv pacts of lumps of lading wh1ch may accio stiff and stron dentally fall upon them, these parts being so that distortions would not ordinarily Jresu t.

On account of the fact that I provide a top guard member with two webs, a joini so ing flange, two main flanges and one lateral flange extension, my members are exceedingly strong and well adapted to serve as the top chordspof the carsides ory ends and also obviate deformations. By reason oftheir large radiiof gyration and their large section moduli in all directions, they are further well adapted to serve the purpose, and they are very firmly secured to the upper portion of the car side by vmeans of two `rows of rivets.- My top guard members are preferably formed of rolled steel with all their portions integral, as illustrated.

Alt ough I have described and illustrated my invention inconsiderable detail, I do not wish to be limited to the exact and specific details thereof, as shown and described, but may use such modifications in, substitutions for, or equivalents thereof, as are embraced within the scope of my invention, or as pointed out in the claims.

Having thus described my invention, what I claim and desireto secure by Letters Patent is 1. An integral flanged bar secured at or near the upper edge of a car side comprising a pair of web members spaced apart, a flange joining one pair of extremities thereof,

flangesprojecting outwardly from the other extremlties and a lateral flange extending from one of the flanges approximately parallel to the pair of webs. TX

2. An integral flanged bar secured at or near the upper edge of a car side comprising a pair of web-members spaced apart, a join- .a trough member with a body portion of general hollow trapezoidalcross section, a pair of inclined webs spaced apart, the margins being integrally connected by a comparatively thick joinilw flange, a pair of flanges outwardly extent ing from the other margins of said webs, said angestapering outwardly, one of said flanges being provided with a comparatively short lateral projection at its margin extending approximately-parallel to yand away from the webs aforesaid.

4. The combination with a ear side of a flanged member of trough section provided with a pair of webs spaced apart and a flange jolning the margins thereof, a pair of anges laterally extending from the other margins thereof and a flange laterally extending from one of the flanges aforesaid, said .main flanges being secured to the upper portion of said car side.

5. The combination with the edge portion .of a car side of a flanged 'bar of trough section, comprising a pair of web members spaced apart and inclined toward each other, one pair of their margins being integrallyjoined by a thicker flanged portion, a Ipair of flanges extending outwardly from the other margins of said -web portions, and a flange laterally extending from one of said flanges substantially at right angles thereto.

6. The combination with the edge portion of a car side of a flanged bar, comprising a trough section with a pair of flanges extending outwardly from the margins of the trough and an upper lateral flange, said bar being secured to the car side by means 'of the pair of flanges.

7. The combination with a car side of a flanged bar of trough section having a thick joining flange and provided with a pair of outwardly extending flanges adjacent to and secured to the upper portion of said car side.

8. The combination with a car sidelof a flanged bar of trough section provided with a pair of outwardly extending flanges adjacent to and secured to the upper portion of said car side and a lateral flange extending signature.
