The invention relates to railroad rolling stock, and consists in an improved construc-V underframe for association with cars of the above type which will employ asa substitute for the center sills a single member so shaped as to utilize the space defined by the usual .vertical members of the center sill.

Another Objectis to provide an underframe for tank cars employing a cast one piece member which will Vconstitute the bottom plate of the tankand also form a substitute for the usual spaced center sills.

Yet another object isto provide an under frame for tank cars employing a cast one piece member forming the bottom plate of the' tank which will be so shaped as to increase the space available for carrying the contents.

A further object is to provide an underframe for tank cars which will serve to inV erence characters are used to designate like parts Figure 1 is a top plan view of the undern frame of the presentv inventiony showing' the one piece longitudinal member secured tot'h'e bolster and the end frame; Y

The improved under frame form-ing the supporting structure for tankY cars comprises the usual end sillv member 10 having integral side members 11 braced by integral braces 12,

the side members being connected to a transverselyextenfdin'g bolster member 13; This end struct-ure is also braced by corner braces 14 and has cast integral therewithV striking blocks 15, a carrier iron 16 and pushpol'e pockets 17. vThe bolster 13 is formed as an integral part of a centrally disposed longitudinal member 2O having a bottom portion 21 and vertical side Walls 22, which member eX- tends from end to end of the car and forms the bottom plate of the tank car and also serves as a substitute for the usual center sills.- The member is subjected to a uniformly disftributed hydrostatic pressure due to the fluid contents of the tank, and is therefore braced the bolster member, and the usual draftl sills, .the latter being designated 18. The bolster 13, in additionto the vertical: wallA 23, is provided W'ith'a similar Wall 25 spaced therefrom and extending the full length ofthe member.A It is to bev understood that the construction" above described and'illustrated in Figure 1 forms the end structure of the ,underframe andis duplicatedjat,bothends of the car. It

is seen then, that the Well portion ofthe member 20 is defined at either end bythe walls 23j `of the bolster and themember continued'over.

the bolsterby the bottom Walls 24. y

The bottom wall 21 of the longitudinal member has cast integral therewith the brake supporting parts designated as 26, 27 and 28, and is also provided with a draining 'opening 30 which consists of a separate member 31 threaded as desired and welded in place within an opening provided for the purpose in the bottom member. A steam connection 32 is similarly provided for introducing steam into the tank for heating the contents, such as crude oil, to induce a more rapid flow in cold weather. The arrange* ment for providing cross-overs for the drain pipes 33 comprises a channel-like compartment including walls 34 which are spaced in parallel arrangement with each other and are supported from the cross ties 19. Brackets 35 are provided at each end of the channel compartment which serve` to secure the pipe 33 in position. It is understood that the construction need not be limited to this Jform of cross-over, as the same may assume merely the form of a pipe extending diagonally of the cross ties-19 and integrallyT joined to the side Walls 22 and provided with flanged ends for connection with the usual drain pipe.V

' `The longitudinally extending member 20 V has also integrally formed thereon on the outside of the walls 22 brackets designated 36 which are located at intervals between the bolster and vprovide the supporting means for thelongitudinally extending floor boards 37. F or this purpose the brackets 36 have riveted or otherwise secured to thema hori zontal brace 38 and an upwardly extending brace 39.` The running'boards 37 are located on each side of the tank and are supported at their ends by the bolsteriand at intermediate points between by the braces 39. rIhe niember'QOfprovides the bottom plate of the tank and is adapted to have the re'- maining tank structure secured thereto. The end portions 40, `Figure 2, are secured by riveting or=othersuitablc means to a raised part il of the member 20 provided for the purpose. The side sheets l2 are secured in a similar manner to the side portions of the Vmember 20. The construction, however, is

not limited merely to riveting the members together, as it is possible to machine the y overlapping parts and weld the same, which would be in addition to the rivets. It is also contemplated to extend the brackets 36 upwardfbeyond the riveted oint, in which case the brackets would be riveted to the sideY sheets 42. This construction allows the brackets to assume some of the strain induced to be limited by the exact embodiment of the device shown, which ismerely by way of illustrationand `not limitation, as various and other forms oi the device will of course Vbe apparent toV those skilled in the art' without departing from the spirit of the. invention or the scope of the claims.
