W. P. MURPHY 'TANK FOR RAILWAY CARS Filed Aug. 27, 1950 Inventor Iberi -[11117059 Patented May 24, 1932 UNITED STATES PATENT oFFi-E WALTER" P. MURPHY, OF CHICAGO, ILLINOIS, ASSIGNOR T0 UNION METAL PRODUCTS COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF DELAWARE TANK FOR RAILWAY CARS Application filed August 27, .1930. Serial No. 478,698.
This invention relates to a tank freight car forrailways which comprises a tank mounted in horizontal position upon an underframe, which underframe is mounted upon trucks. Such cars are used for the transportation of materials of liquid or semi-liquid form, such as acids, alcohol, ammonia, oils, paints, milk, vinegar, etc., and even gases are hauled in such cars. The movements of the liquid or semi liquid loads causes severe impact blows against the ends of the tanks, and one ofthe objects of this invention is to provide an end for such a tank made of cast metal with integral means to reinforce the tank end against the above mentioned impact blows.
Another object of the invention in making the tank end of cast metal is to obtain an end which resists corrosion, thereby obviating the necessity of lining the end of the tank which, owing to its dome-like shape, is very difficult to line. It is a simple matter to I line the cylindrical shell. Such linings are used to keep certain liquids out of contact with the rolled steel parts of the shell which are subject to corrosion.
Another object of the invention in making the tank end of cast metal is to provide means to readily adjust the strength of the end to the strength requirements of the particular part of the tank end.
Another 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 eliminate the possibility of loose connections which would permit relative motion between the component parts of the 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 upon any device which reduces the number of parts and joints as these are the weak parts of the car and the more such weak parts are eliminated, the longer the life of the car.
In the drawings:
the "shell of the tank is attached. flanges may be welded or riveted tothe tank shell and tank of the truck; 4 tank shell; 5 tank head; and i 6 safety railing. 7
Figs. 2 and 3 show my improved tank .head consisting of an integral casting comprising a central portion 10 which is preferably bulged outwardly and a continuous inwardly projecting flange 11 adjacent the perimeter of the central portion to which These end. I prefer to provide a rib forming a shoulder 13 on the tank end against which the shell 4 of the tank is abutted. The rib 12 being preferably reinforced by a 'plural-' ity of exteriorly positioned brackets 14:, as ,shown in Fig. 6. The flange 11 is preferably deepest (15) adjacent the bottom of the tank .to.. accommodate the greater stresses at this portion ofthe tank, and furthermore, the
. fl ange, gradually decreases in depth toward the top (16) of the tank, as shown in Fig. 3.
The deeper flange permits of more riveting or welding.
To provide a better attachment to the shell the: tank end maybe further reinforced by .a-p1ura1it o brackets 20 connecting the central portion 10. of the tank end to the- [flange 11' which are spaced around the perimeter of the tank end. These brackets are pref- ,erably wider and-preferably deeper adjacent the deeper part of the flange so as to furo ther reinforce the tank end where the great er fst'resses occur. 7 further reinforced,jif desired, by aplurality 1 of reinforcing ribs 22 in the central portion with their opposite ends merging into the -..centra1 portion between adjacent brackets,
The tank end may: be
' ed to resist the stresses imposed upon the casting, thereby obtaining a very strong end in consideration of its weight.
Figs. l and 5 show a modified form wherein aplurality of smaller brackets 30 are positioned adjacent the perimeter of the central portion 10 to connect it to the flange 31.
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.
