cAsr METAL PLATE 7 7 Application filed November My. invention relates to theconstruction of railway carsandmore particularly torthe end plate thereof.- 1 The end plate of a railway freight car is the upper horizontal struc- "5 tural member spanning the-"distance between the opposite corner posts and oppositeside plates and usually formed so as to'support 'theroof.

The'object of the invention is to provide 'io a single piece cast metal" end plate formed with integral means for attachmentto the side plates and to the corner posts andalso preferably they end wall and roof of the car and to so form such member as to provide is a waterproof connection between theside plates and cornerposts' and also between the roof andendwallofthecar.

. Another object is to formsuch cast metal and removed from the other elements of the car. I

, Another object'is to form the component parts'of the end plate of asingle piece cast member so as to eliminate the possibility of By nature of" their requirements railway freight train cars are out of doorssubstantially all of the time, therefore, are subjected tocorrosive action of the elements, and while paint and other non-corrosive coatings have been applied to the car parts, such protection does not remain on such car parts. Cast metal, particularlycast steel, has more than twice the resistance to corrosion than rolled steel,

therefore, one of the objects ofthe invention is tomake the end plate of cast metal, prefend plate so that it can be readily detached loose connections which-wouldp'ermit rela- 1 tive motion between the component parts of. the end plate and between the adjacent frame" ect is to eliminate the cost and is not only expensive intime and money, but

erably caststeel, to enable it to resist co'rrosion. Furthermore, to provide aconstruction wherein the metal can bedisposed and positioned to accommodate the stresses set up by the car in service. Such a cast construction necessitates aminimum amount of material for strength requirements. I H In the drawings:

posts 3 of JZ-shape formation adjacentthe f ends "of the respective side plates. The end plate consists of a single piece cast =metal comprisinga Z-shape portion consisting'of a web 4; an'upper flange 5 and a lowerflange :6, which portion extends between the oppositeside plates 2and also between the oppo- I site. corner posts 3 and is formed ateach end with a lateralextension 7, which isalso'pref-. erably 'Z-shaped and whichis secured to the adjacent side plate and corner post; In order'to form arigid attachment and elimi nate possibilities of a loose connection, I prefer to attach the web I of the -end plate. to the web 8 of theside plate the flange 6 of the end plate to the flange?) of the side plate. j

The 'lateralextension 7 overlaps the end of the side ,plateQ and the corner post 3and provides a weatherproof construction. 1

, The end pla'te' flange 6 overlaps and is securedto the end wall 12 of the car. This :fiangealso preferablyis secured to the web and flange of the corner post 3 and is pref-- erablyextended further and secured to the depending flange of thelside'plate 2.

roof- 16 comprises a rigidmetallic sheet which overlaps and is secured to'the flange 5 Of the In the form shown in Figs. 1, 2 and 3 the end plate and is also overlapped and secured to a flange of the side plate 2.

The roof shown in Figs. 4, 5 and 6 is supported by ridge pole 20 and purlins 21 which rest upon a horizontal rib 22 formed integral with the flange 5 of the end plate, which rib merges into the flanges 23 of the extensions 7 and is preferably increased in width (24) toward said extensions to provide a gusset effect. This rib stiflens the upper margin of the end plate flange against the tendency of the car to weave in service and also the tendency of the roof to shift by its inertia when the car stops. 7 j

I also prefer to provide brackets which stiffen the relation between the flange 5 and web 4 of the end plate and also may be altered to support the running board bracket 27 In the form shown in Fi gs. 7, 8 and 9 the end plate is provided with an outwardly extending flange 30 supporting the roof 31 to which it is secured. The flangeconforms to the slope of the roof whether it be rounded, as shown, or apexed. Brackets 3233 are provided to support the longitudinal roof framing members when they are used. In this modification the upper flange 5 is provided with a gusset 34 which extends over the side plate 2 and merges into the extension 7. The corner post is omitted and the end wall 12 is provided with a flange 35 which is secured to the member 36 which is an integral part of the end plate. The side wall 38 (shown as wood) is secured to the flange 35. These figures, 7, 8 and 9, also show a load lifting beam 36 which preferably extends longitudinally of the car and is spaced apartfrom the root sheets so that a chain, hook or other load lifting apparatus may be conveniently attached to it. This beam is supported by the bracket 33 which is integral with the end plate. Numeral 39 shows the running board bracket.

The accompanying drawings illustrate 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.
