Figure'? is a vertical sectienal View on K line 7-7 of Figure 1. 'i l This invention relates to a new and useful improvement in underframes for ore cars and is of thattype shown in the copending application file-d by me on the 21st4 day of July, 1922, Serial No. 576,526.

The object of my present invention is to- J construct an underframe for ;ore cares in' the form of a single casting, preferably cast steel, which underframe is characterized by an opening in the center, the end walls o said opening being curved and obliquely disposed soas to form the lower portion-of side walls of ythis opening are vpreferably formed by obliquely disposed overhanging eaves or ledges under which are arranged perforated lugs `for the attachment ofthe hopperdoors (not shown).A By thisconstruction, the hinges bywhich the hopper doors are secured to the underframe. are protected from the lading and any water` which usually seeps through the lading, will be'shed into the hopper opening to one side '35 of the hinges so that said hinges are not liable to freeze in cold weather.

lMy improved cast steel'underframe, other than the peculiar construction form-ing the hopper opening, has side sills, draft sills, end platforms. and other parts containing-novel details all of which are hereinafter more fullv set forth and claimed. 's That part of the underfram'e casting which D' forms the end sill preferably includes a4 vertical web 1. the middle portion of which lis relatively deep and is 'provided with a--. l

"shown). The horizontal Webs 7 constituting recess 2 for the -reception of.v the drawbar. `this portion of the 'web constituting a Wall which forms substantially the well known 5 dead block. ,l `1

Shallow portions 3 of the end sill extend tothe sides of the car and are there integrallyw'connected with `the web `flanges 4 of the car underframe. A; horizontal web i922. Yserial No. 576,527.

.7 forms a platform integrally uniting the end sill flanges ,side sills and draft sills d' which may be provided with the usual stops and lugs for draft rigging. The vertical Webs of these draft sills diverge slightlyv at their innerends and are connected to an obliquely d1sposed curved web 8 forming a ypart of the end wall of the hopper.

Rein'forcing Webs 9 are preferably 'spaced from the'wall 8 and, as shown, (in lFigure 7), thebottoinange of one of these reinforcing webs 9 may bey extended outwardly and provided `With a center bearing 10 whereby a swiveling' truck may be employed with this type of underframe.

The ends of the deep portionl of the end sill web' constituting the deadblock are conoined' to divergingvertical disposed Webs 11 which' (see Figure 1) throughout the major portion`of thelength of the underframe runy parallel to each other and to vreF f inforcing flanges 4- before mentioned and constitute thelwebs of ,the car sideY sills. These webs y11 throughout the major portion of their length (see Figures 3, 5, and 7), are provided withv outwardly extending bottoni flanges 12, and with the top flanges 13 which are 'preferably flush with the horizontal web 7 constituting-end platforms. At

`points intermediatetheir lengths, the side sills composing `the parts I1, 12, and13 are reinforcedv by transversely disposed Webs 15, and the horizontal flange '13 is-,providedwith a finishing surface 16 to which the knee` braces (not shown) for supporting the side walls of the hopper may be secured; Y l

' The-inner edges of the .horizontal flanges 13, at the' sides ofthe'hopper opening, are

provided with obliquely disposed,l eave extensions 17 ccnistituting the 'Water-shed for the hinge lugs 18 see Figures 1, 4, and 5)". c The obliquely disposed. end Wall 8 is preferably enlarged at its lower end, as-shovvn `in Figure 4,- and provided with .a downwardly extending lug 8u for'the attachment of the hopper door operating machine (not platformsare preferably recessed, as vat 7%'- so as to provi-de a handhold opening bridged by a grab iron (not shown). Thenishing surfaces 7b extend above the horizontal Webs 7 and in order to provide bearings for truck liquelv disposed, vertical webs constitutingV disposed web 11 (see Figures 1 and 6)l which .webs A11 and 19 together with their transversely disposed reinforcing webs 20. constitute a box-like structure lor carrying a horizontally disposed bearing plate Q1.

vThis bearingplatc is designed to provide support for truck side frames of the type shown in United States Letters Patent No. 1,858,016, granted lo l-l. lll. Ptiager on the 9th day of November, 1920.

lVhen the underframe is mounted upon swiveling trucks, suitable side bearing projections mayv be provided as illustrated at 22. in Figure 7.

Other modifications of in v invention may be made without departing from the spirit thereof as expressed in the following claims.

1. A cast steel underframe having a centrally arranged hopper opening, the end walls of which are curved and obliquely disposed.

y 2. A cast steel underframe having a central hopper opening the sidewalls ofvwhich are inclined to provide a water'and lading shed, said underframe having hinged members located under said inclined shedding walls. y 4

3. ln a cast steel underframe, an integral bolster, end sill and side sills, the latter converging towards each other from the bolster to the end sill.

vel. A east steel underframe having side and end sill members and horizontal flanges at the ends of said members constituting end platforms-having raised portions forming finishing surfaces. 5. A cast steel underframe having spaced end sills, side sills connecting said end sills,

horizontal flanges extending inwardly fromsaid endand side sills and forming platforms at the ends of the car. and draft sills integral with said platform vforming flanges.

6. A cast steel underframe having side and end sill members` the horizontal flanges thereof at the ends of the underframe for1ning end platforms. and draft'sills integral with said platform flanges, the vertical webs of said draft sill members divergingat their inner ends.

. 7. A cast steel underframe having hori- Izontal flanges constituting end platforms, and a centrally located hopper opening, the side walls of which hopper opening are obside sill members on each side of said openinlg and vertical webs constituting draft sills extending from the ends of the underfraine to the end sills of said hopper opening.

8. A cast steel underframe having side sill members composed of vertical and horizontal flanges, transversely disposed rein- Leaaeei forcing webs and integral linishing surfaces of the `top surfaces of the horizontal flanges of said side sill members.

9. A cast steel underframe composed of side and end sills, each of said sill members being made yup in part of vertically and horizontally disposed webs or flanges, one of the vertical flanges of the side sill member being provided with a or bend forming a handhold recess designed to be bridged by a grab iron.

' 10. A cast steel underframe including side sill-members whose vertical webs converge towards each other at the ends of the underframe and horizontally disposed bearing plates for truck side frames integrally connected to the vertical webs of said side sill members.
