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.
