2, 1932. I G. G. GILPIN ET AL 891223 Original Filed April 8, 1929 Patented Dec. 20, 1932 UNITED STATES PATENT OFFICE GARTH G. GILPIN, OF RIVERSIDE, ANB ARTHUR E. SMALL, OF CHICAGO, ILLINOIS, ASSIGNORS,`BY MESNE ASSIGNMENTS, TO GENERAL STEEL CASTINGS CORPORATION, 0F GRANITE CITY, ILLINOIS, A CORPORATION OF DELAVARE RAILWAY CAR Serial No. 550,937.y

The invention relates to railway freight cars and particularly that class of equipment known as hopper cars7 wherein the lower portion of the car body comprises a plurality of hoppers. These hoppers are disposedon the opposite sides of the center construction of the car and cross bearers are positioned between adjacent hoppers which are secured to the opposite side walls of the car and also connected to the center construction. Some cars have just one cross bearer, while others have a plurality of cross bearers with hoppers disposed on bothV sides thereof. Other railway dump cars do not have any cross bearers but have a relatively long longitudinally extending door on each side of the center construction. There are other numerous types of railway hopper cars which need not be enumerated here and to which this invention will apply. n

In such type of cars the moisture in the lading, due torain, melting snow, thawing of the material, etc., accumulates adjacent the bottom part of the lading so that that part of the lading in Contact with the hoppers, center construction, cross bearers and other .associated parts becomes wet and holds the moisture in contactV therewith causing excessive corrosion when these parts are made of rolled steel, especially if such rolled steel parts have been deformed by pressing. tis common practice to use such doors for transporting coal and when moist coal, particularly coal dust, is allowed to remain in contact with the rolled steel parts, the acid formed thereby eats into the steel parts.

Such corrosive and acidic action vrapidly eats away the rolled steel and experience shows that these hoppers and associ ated parts must frequently be replaced, which is expensive, not only from material and labor cost, but also by keeping the car out of service.

An object is to eliminate the cost and delay in fabricating the numerous component parts of the present structural steel car parts.

Another object of forming the car part of cast metal is to eliminatethe ,possibility of loose connections which would permit relative vmotion between the component parts lof th-e car part, as it is common knowledge that the vibration of the car in motion, due to rough and uneven track, and steel wheels rolling on steel rails, together with longer trains and high speeds in present day practice, cause riveted joints and built-up sections to work loose and the railroads look with favor uponl any device which reduces the number of parts and joints as these' are the Original application led April 8, 1929, Serial No. 353,494. Divided and this application filed July 15, 1931.

weak parts of the car and the more such weak parts are eliminated, the longer the life of the car.

rin object of the invention is to form the parts of the car which come in contact with the lower part of the lading of cast metal to 6, which sills and cover alate extend between Y the body bolster and usually therebeyond to accommodate the draft gear. The side walls may be of a truss or a girder design. In the form illustrated the top (7) Aand bottom (8) chords of the side girder arer connected by the web plat-e 9 which also is the load retaining means of the side wall. To meetstrength requirements it is preferable to make the top and bottom chords of rolled steel. In order to save weight and material it is desirable to make the web plate also of rolled steel.

The car illustrated includes an integral casting comprising a hopper on each side of the center construction, a center construction hood and part of a cross bearer. Two of such castings (preferably duplicates) are secured together to forin the complete hopper part of the car, which united castings are then merely secured to the center construction and opposite side walls of the car. Each part of the cross bearer comprises a web plate 13 with the upper stillener 14 and oppositely disposed sloping lower portions 15 which direct the discharging lading into the hopper. The cross bearer is arranged to protect the lower side chord 8 and the lower portion of the web plate 9 from the lading. The cross bearers straddie the center construction 4 and are secured thereto in any convenient manner. We also prefer to cast hinge lugs 16 integral with this cross bearer to support the hopper door 17. rI`he brace is secured to the side wall and also to the outer end of the cross-bearer 12 and comprises a diagonal member 18 extending from adjacent the top of the side wall to substantially the middle of the cross bearers. It is also provided with an extension 19 connected to the upper chord 7 to brace that member against deflection. The hoppers 2O on opposite sides of the cross bearer are preferably cast integral therewith. These hoppers comprise an inclined portion 21 with oppositely disposed substantially upright portions. The inner (22) of said upright portions is connected to the center sill and arranged to protect it from the lading. The outer (23) of said portions is connected to the side wall and arranged to protect the lower chord (8) from the lading. The integral reinforcing ribs 24 extend continuously around the inclined portion and the upright portions of the hopper. The hopper is also preferably reinforced with longitudinally extending integral ribs 25 below the inclined portion.

The accompanyingr 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.

This is a division of our co-pending application No. 353,494, filed April 8, 1929.

We claim:

1. In a railway car, the combination of a center sill, a side wall, a cross bearer extending between and secured directly to the center sill and the side wall, said cross bearer formed of a pair of members secured together, each consisting of an integral casting comprising a vertical web, a downwardly sloping portion extending from said web, and an upper stiffening flange.

2. In a railway car, the combination of a center sill, a side wall, a cross bearer extending between and secured to the center sill and the side wall, said cross bearer formed of a pair of members secured together, each consisting of an integral casting comprising a vertical web, a downwardly sloping portion extending from said web formed with hinge lugs, and an upper stiifening flange.
