27 Claims.

My invention relates to the construction of railway freight cars, and more particularly to the walls, floors or doors thereof whether such parts are rigidly secured to the car proper or hinged thereto, and comprises integral cast metal members forming a frame in combination with preferably cast metal panels or units which form the load retaining portions of the walls, floors or doors of the car and which are rigidly and removably secured to the frame.

One of the objects of the invention is to form such a frame (or a panel) of cast metal having the structural members and the means for attaching them to the other parts of the car formed integrally and to distribute the metal in the frame to accommodate the various service stresses with the least amount of metal, thereby obtaining a very light but eflicient structure, resulting in increased life of the device and reduction in maintenance cost as compared to the composite structures now in use.

Another object is to provide a drop end gate for a mill-type" railway gondola car by providing pintles or trunnions at the lower corners of the end wall of the car adjacent the floor of the car which pivotally engage sockets in an adjacent part of the car, such as the side wall, corner post or end sill. Another object is to provide means to support the weight of the drop end gate in upright or closed position, preferably independently of the hinging means.

Another object is to provide an end frame for such a car having integral end sill, corner post and means to accommodate the 'hinging means of a drop end gate.

Another object is to provide a cast metal corner post having integral means for attachment to the side wall and integral means for forming an abutment for a drop end gate which post preferably also has means to accommodate a hinging means for a drop end gate.

By nature of their requirements railway freight train cars are out of doors substantially all of the time, therefore, are subjected to corrosive action of the elements, and while paint and other non-corrosive coatings have been applied to the car parts, such protection not only has been found to be expensive in time and money, but the lading removes the coating. This is particularly true of the inside of open type cars which are turned upside down in unloading machines causing the load to slide across the inside surface of the car body and also when the discharging load slides across the surface of a drop door and also when the long lading rests upon the lowered drop end gate of a gondola car the friction .thereb,ei"* tween caused by the movement of the 63.18150 removes the protective coating from the endg'ateJi" Furthermore, certain ladings, such as sulphur, wet coal, which forms sulphuric acid, and saline 5 water (in refrigerator and stockgcars) cause rolled steel or iron to corrode. On'accountof its increased strength rolled steel lin the form-20f: plates and bars has supplanted wood-L in carconstruction but the corrosiveaction of. the ele "10 ments eats away the rolled steel or 'iron material ly, reducing their strength and their len'gthflof life. This applies. to both the load carryingimeni bers, such as the sills, plates andxcdiaphragm and also to the lading retaining members,' :su'c 15 as side and end walls, floors, hopperswhcipper doors, etc. It has been found thattcasti m'etal particularly cast steel, has more-than twice resistance to corrosion than rolled steel,"- the' fore, one of the objects of the: invention is; I make the car part of cast metaLupreferablycas' steel, to enable the car part-to-resistcorrosion and furthermore, to produce a: constructio wherein the metal can be disposed ahdqaositioned to accommodate the stressesxsetupiby they car in service. Such a cast construction *n'eces.

sitates a minimum amount of material li'fO strength requirements. a ii Another object is to eliminate-,1the icostasand' delay in fabricating the numerousm'complonen parts of the present structural steel carpar'tsin Another object of forming the ,cartpartaofzcast metal is to eliminate the possibilityof IOOSEAC'OH nections which would permit relative -.motion.be-.- tween the component parts of the car part-,rasi-itv is common knowledge that the vibrationa'iofrrth car in motion, due to rough and, uneven-:,track and steel 'wheels rolling on steel rails togethe with longer trains and high speeds inpresentcda' practice, cause riveted joints and builtrgup section to work loose and the railroads lookgwithbfavor'.

upon any device which reducesthenumbemjo parts and joints as these are the weak apartso the car and the more such weak partsare elimi nated, the longer the life of the'car. .1 My invention not only relates to the feature;

of having a car part consisting 0f, ,a ,.'cast,;frame in combination with a plurality of panels, but also consists of forming metal panels of specific configuration top certain advantages, particularly the dispositionof, the metal to accommodate servicestressesrandxt resist corrosion, and another object is to hinge sucha cast metal panel to the body of the car to form a door.

In the drawing:'

Figs. 1 and 2 show a typical application of my invention to a railway car.

Figs. 3, 4, and 5 show a drop end door or end gate of a preferred construction according to my invention.

Fig. 6 is a fragmentary view of the corner post and endsill.

The drawing shows the preferred form of my invention'wherein the end frame casting consists of a cross bar or end sill I with integral upright corner posts 4. Each corner post 4 comprises a flange 6 extending longitudinally of the car for attachment of the side wall 8 of the car and ,another flange I ll substantially normal thereto adapted to provide an abutment for the drop end gate I! when in upright or closed position, as shown in Fig. 2 in solid lines, and preferably also when in lowered or open position, as shown in Fig. 2 in dot and dash lines. The flange I extends below the end sill (2) for attachment to the side sill H of the car. The panel or drop end gate I! has a pintle or trimnion II which engages a socket it in the end frame either in the cross bar portion 2 or the corner post portion 4 thereof to form a hinge construction. The bottom 20 of the panel is preferably semi-cylindrical concentric with the hinge point of the pintle and engages an arcuate surface 22 in the cast metal end sill. I prefer to arrange this construction so that the vertical weight of the door and also the horizontal load thrust are taken by the end sill 2 and not by the pintle I! so that the pintle is merely a guiding hinge.

The drop end gate is preferably provided with outwardly extending marginal flanges engaging the corner posts when the gate is in upright position, so as to present a smooth surface 48 toward the interior of the car.

In drop end gates it is preferable that they be.

as thin as possible so instead of increasing the depth of the reinforcing ribs I! and the side flanges Oil-8| I prefer to increase them in width adjacent their middle portions (82), thereby increasing their strength without increasing their depth. Sometimes the long lading is allowed to rest directly upon the door when it is in a lowered position causing'considerable friction between the load and the door, therefore. I prefer to provide a wooden supporting or anti-friction strip 83 of greater depth than the gate to support such long lading. The strip I3 is bolted to one of the ribs or preferably positioned between two of the ribs and bolted thereto, as illustrated. I prefer to position these bolts so that they can be installed after the door is in a lowered position, and furthermore, if bolts passed through the door the heads of the bolts would damage the woodenfloor.

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.
