0]! ST. LOUIS, MISSOURI, ASSIGNOR T0 GENERAL STEEL CASTINGS RAILWAY VEHICLE UNDERFRAME Application filed June 27,
My invention relates to railway rolling stock and consists in a novel underframe structure particularly adapted for tank vehicles, although some features of the invention may be embodied in structures which are not used for tank purposes.
The main and general object of my inventionis to provide a simple, rigid, economical underframe, preferably forming the bottom of the vehicle tank and including, as an integral part, one or more reservoirs for fluids to be held separate from the fluid in the main. tank of the vehicle.' As an illustrative example, the tank vehicle may form a locomotive tender and may contain reservoirs separate from the water tank compartment for compressed air or for fuel oil or gas, or other fluids.
Preferably, the separate reservoirs will -merge with the tank-forming portion of the underframe and will constitute, in part, sill members for the underframe and, in the selected embodiment of my invention shown in the accompanying drawings, the structure is in the form of a casting, although it is within the scope of my invention to form two or more parts separately and then unite them by welding into an integral whole, which will possess many of the desirable features attending a one-piece casting. In the drawings- Figure frame.
Figures 2 and 3 sections taken on the lines 2-2 Figure 1.
Figures 4:, 5 and 6 are vertical transverse sections taken on the corresponding section lines of Figure 1.
The underframe is of a general rectangular shape, having a substantially horizontal bottom web 1 extending from side to side of the underframe and provided with upstanding longitudinal sill elements 2, 3 and 4 and with transverse end sills 5, bolsters 6 and intermediate reinforcing ribs or transoms 7 This web forms the bottom of the vehicle tank and the superstructure side sheets 8 and end sheets (not shown) may be secured to the side sills 2 by riveting or welding, or

both. The intermediate portion 9 of the bottom web is depressed to provide increased capacity of the tank structure and to lower the center of gravity.
Formed integrally with the web 1 and with sills 4 are cylindrical reservoir members 10, 11 and 12 disposed longitudinally of the underframe with their walls merging with the web 1 and sills 4 or, in other words, with In my preferred structure, I show a series I of three reservoirs arranged abreast of each other, reservoir 10 being located intermediate the spaced sills 4 and reservoirs 11 and 12 being located on the outside of the latter and between the same and the side sills 2. I also show a fourth reservoir 15 located intermediate the left hand bolster and the corresponding end of the underframe and between the center sills, there being no additional reservoirs on the outside of the sills.
Obviously, one or more reservoirs could be provided at other points on the underframe Web without departing from the spirit of my invention and, if desired, the reservoirs could extend transversely of the underframe instead of longitudinally thereof but I prefer the longitudinal arrangement as thereby the reservoir walls can be utilized to transmit a portion of the longitudinal forces applied to the underframe.
Another feature of my. invention is the provision of a brake cylinder structure formed integrally with the bottom web 1. This structure includes the brake cylinder body 16 and, preferably, one of the brake cylinder heads. Figure 3 shows the non-pressure head 17 formed integrally with the web 1 and shows the latter elevated, as indicated at 18, to form a recess for accommodating the brake riggin applied to the pressure head of the cylin er. Pressure head 19 will be formed separately and secured to the cylinder in any approved manner.
The described structure provides a rigid underframe with reservoirs for air or other purposes, and a brake cylinder, integrally united and free from bolts and rivets which require frequent inspection and tightening in order to maintain dition. By locating the reservoirs above the bottom web of the tank, the latter may be located at a lower level than otherwise possible without projecting beyond the clearance limits which must be observed. Merging of the reservoir walls with the sills and bottom web affords increased strength for each of these elements and also affords economy of material over a structure in which complete reservoirs would be formed separately and then attached to the underframe.
I claim:
1. A railway tank vehicle underframe hav ing a portion forming part of the wall of the vehicle tank and also forming a part of the wall of a fluid chamber or reservoir separate from the vehicle tank.
2. In a railway vehicle underframe, a web member extending generally in a horizontal direction and forming the bottom of a tank structure, and a separate fluid chamber integral with said web member and projecting upwardly therefrom.
3. In a railway vehicle underframe, a web member extending generally in a horizontal direction and forming the bottomof a tank structure, and a separate fluid chamber integral with said web member and projecting upwardly therefrom, a portion of said web forming a part of the wall of said chamber.
4. A railway vehicle underframe having spaced longitudinal sills and a horizontal web connecting said sills and forming a tank bot-tom member and includingv as an integral part thereof a reservoir for fluid stored sepa; rately from the contents of the tank.
5. In a railway vehicle underframe forming the bottom of a vehicle tank, a sill member, and a separate reservoir having a wall merging with said sill member.
6. In a railway vehicle underframe, a longitudinal sill, a substantially horizontal web extending laterally from said sill and forming a tank bottom member, and a fluid chamher, said sill and web being integral with each other and having portions forming parts of the wall of said chamber.
7. A railway tank vehicle underframe comprising center sill structure and a substantially horizontal web forming the bottom of the vehicle tank, and separate reservoirs located on opposite sides of said sill structure above said web and integral with said web and sill structure.
8. A railway tank vehicle underframe comprising center sill structure and a substantially horizontal web forming the bottom of the same in proper con- Leeases the vehicle tank, and separate reservoirs located on opposite sides of said sill structure above said web and integral with said web and sill structure, portions of said web and sills forming parts of the walls of said reservoirs.
9. In a railway vehicle tank underframe, a substantially horizontal web forming the tank bottom, an upstanding sill integral therewith, and a reservoir above said web having a wall merging with and formed in part by said sill and web.
10. In a railway vehicle underframe, a pluralityof reservoirs disposed side by side and extending longitudinally of the underframe with their adjacent walls merging with each other and constituting sill-like members of the underframe.
11. In a railway vehicle underframe, a bolster structure, and reservoir members disposed longitudinally of the underframe, one on each side of said bolster, with their ends formed by the bolster structure.
12. In a railway vehicle underframe, a bolster structure comprising spaced side walls, reservoirs extending longitudinally of the underframe, one on each side of said bolster structure, with an end wall of each reservoir formed by a respective side wall of the bolster structure.
13. In a railway tank vehicle underframe, a horizontal web forming the bottom of the tank, a reservoir integral with said web and extending upwardly therefrom, and a brake cylinder integral with said web and extending downwardly therefrom.
14. In a railway tank vehicle underframe, a horizontal web forming the bottom of the tank, a reservoir integral with said web and extending upwardly therefrom, and a brake cylinder integral with said web and extending downwardly therefrom, portions of said web forming a part of the wall of said reservoir and of the wall of said cylinder.
15. A railway vehicle underframe having a portion forming part of the wall of a vehicle tank and also forming a part of the wall of a fluid chamber or reservoir separate from the vehicle tank.
In testimony whereof I hereunto aflix my signature this 23rd day of June, 1930.
