RAILWAY CAR.

Application filed January 7, 1926.

My invention relates to railway cars and particularly to the framing of freight car superstructure. Some of the details of my invention are especially adapted for hopper car structure, although my invention may be utilized in other car framing as well as in hopper cars.

The objects of my invention are to provide a maximum capacity for cars of the type described; to provide improved connections between posts and side chords and between side and end walls and between side and floor walls and the underfraine structure.

Other special objects of my invention will be referred to in the description, of the detailed structure.

The car underframe illustrated forms the subjectanatter of my copendine application Serial No. 76,479, tiled December 19, 1925, and mounted near its' four corners upon trucks of the lgeneral type described in Patent No. 995 560, issued to H. M. Pager June 30, 191], and more particularly described and claimed in the coi'iendinn` ll'lager application Serial No. 841,706 tiled June 3, N225, which tvpe of truck permits the loca- `tion of the truck very close to the end. of the tlnderfra me and permits the locatitni of the hopper door very close te the cf' Serial No. 79,782.

the truck and therefore close to the end of the underframe. It is always desirable in hopper car construction to obtain maximum capacity for a given length and in some classes of service the length of the car is limited by the spacing of storage bins or other equipment into which a trainload of cars must discharge or with which the cars must otherwise cooperate. Hence the location of the end floors as close as possible to the 'end of the car is especially desirable in such cases and each structural feature or relationship of parts which contributes to such an arrangement or otherwise increases the car capacity, constitutes a real improve ment, ln my present disclosure a number of details helping to secure the above de* scribed result are described and l consider al such as parts of my invention.

The main portion of my car body comprises inclined end floors A, inclined side floors B, and vertical side walls C` the space between the lower ends of the inclined floors A and B being provided with hinged doors D, the structure and mounting of which forms the subject-matter of my copending application Serial No. 67,828, filed November 9, 1925.

The end floor A is shown as consisting of three plates, a fiat ceiitral plate l, and curved and flat plates 2 which are located at each side of the central plate l. Plates 2 curve toward the sides of the car and the longitudinal center thereof and are preferably arranged so that the arc of their curvature is tangent to plate l, thus avoidingr` the provision of an angle at the joints between plates l and 2. Along` a line spaced substantially from plate l, each plate 2 is flattened and bent outwardly toward the side of the car and inwardly toward the longitudinal center of the car indicated at 2a. The outer edge y of the bent portion 2a extends upwardly and outwardly in a. straight line from the lower edge of inclined side Hoor B to a point about halfway up the vertical side wall C and the remainder of plate 2 is shaped and bent to form a tri angular break portion 2 extending at an angle to portion 2 outwardly and inwardly toward the center of the car to meet vertical side wall C and inclined side ioor B, the cuter edge of tien El being' flanged as indicated at '55. parallel the side fluor and walf` and through which rivetel secure the end floor to the si de floo and wall. l

The flat central plate l entendi-5 upwardly and outwardly to a line apliroiiiniately above the striking face of the end sill lil and ie there provided with a top chord angle 8, one flange of which is disposed horizontally and the other lange of which ie inclineddownwardly and rearwardly to be Secured along the upper edge of plate 'l andthe upper edges ot adjacent platee Q, includ ing lthe upper ed es olf :iff/clio e 2". The horizontal flange ol' end top chord 3 torina an end platform proiecting yond the end eill of the car for a liunitei'l oietancc on each eide of the longitudinal center line of the car.,y ae perinitted by the Federal fil-al Appliance rules, and on' each side of this platforin forming portion the end top chord is inclined toward the eide of the car and inwardly toward the longitudinal center of the car to provide Ithe necessary clearance lctween the ende o'l the tope of the car Siders on adjacent care.

Four eide or corner poete l are located at the points indicated and entend upwardly frein the undcrlraiiie tothe top of the car side. Each of there poete fl is of Z-bar ci'oee section with its web extending ransversely of the car side wall and with its outer fla-ngc extending toward the center of the car andits inner flange extending toward the end of the car. The car eide walls C are inounted upon the outer flanges of these poste` and su'pplen'iental eide wall plates 5 are Secured to the inner flanges of these poets (eee FigureS 5, G and 7 It will be noted that these. supplementary eide walls are spaced inwardly freni the outer side of the car to leave a epace adjacent the end ol' the car for clearance around the side ladder rungs 6.

Near the top ot poet- Al vthe flangee of the latter are bent upwardly and inwardly toward the center of the poete, the outer flange T eXtend'n vertically upwardly to very near the top oil the poet and then being' bent inwardly ano upwardly at an angle ol about forty-.live degrees. The inner flange 8 of' the poet starte to incline upwardly and inwardly a substantial distance below the top of the post and terminates at approximately the saine point ae the outer flange 7.

A side top chord 9, preferably conaistinpT of a bulb angle, is carried on the top ol poete land the other side poets of the cai'. This angle ie disposed ae ehown so that its lower flange reste upon the inclined portion et poet flange 7 and ita upper flange is inclined at a slight angle to the inclined portion of poet flange 8.

The plate 5 euppleiiients the end portion of the eide wall and extentie. over the inclined portion of poet flange 8 and the `upper flange of top chord 9L This inclination of plate 5 increases; vthe car capacity over an arrangement in wlich a corresponding plate and the inner flange of the p would extend vertically tothe top of' the can My arrz'ingen'ient also faciiii'fateeI the downward discharge of the load freni ite outernioet point. rlhe outer end of plate 5 vertical and provides a support for the upper end of the ladder poet 6a.

A novel pressed or ci satg'uefet provides a rigid diagonal connection between the side wall and endfloor ol the car without rcducing the car capacity. lt includes. a horizontal flange l0, overlying the horizontal Ylange of the end' top chord 31 a bV iitiall-y channel-ahaped portion ll overly .ng the upper portion of plate 5 and eide top chord 9, and an: inwardly and downwardly inclined portion l2 which entende acroae the angle between the end floor and supplemental plate This; guseet Securely ties chords 3 and 9 to each other and torina a channellike reinforcement for the aide of the car corner, the inclinations of the various portione of the gue-eet aft anglea to cach other Serving to substantially incrceee itaI resistn ance to any distortion. lilith thie corner cenetruction7 the full value of' the end portion of the top chord 9 unnecccsary and the lower flange of the saine may be cut away partly as indicated at 9"L to provide clearancearound the adjacent top ladder' rung 6 which is Secured at one end to the upper flange o'l chord 6 and at the other end to the ladder post 6a.

The upper portione of the car side wall platee C are inclined inwardly over the lower flange of eide top chord 9. fit poets l and at other eelcctcd points; along the Side of the car the flangee of chord 9 are braced by euitable fillers I3. The lower portion ol" Leide walls B are criinped at 3l throughout the length of the aide floor to lit over the eaine and be riveted thereto, thereby eliminatingY any upwardly i'facinp` crevice which niipght receive inoiet'ure and dirt with objei'ftionable resulte.

een additional feature of the nicotine; of the end floor and car side structure ia the provision ot a flange le along' the upper portion of the edge ol section il ol. the end floor. Thin flange ia riveted to supplemental plate 5 and poet flange 8. lt the lower end of flange lei another short flange let is forined freni the edgeV of section 2t. This flange 'ebent at such an angle to the reniaindei' of the end floor plate that it ie parallel with and juxtaposed with the web ol poat- 4 and ie riveted thereto.

Another feature ol iny improved :inperstructure is the supporting of the inclined side floor B and the side wall C upon the car underfraine. ln Figure 3 the side ineni- 'bei' of the underfraine is shown in section and includes a niain vertical flange l5, a horizontal top flange 16 extending inwardly frein flange l5, and a shallow vertical flange Uli loo

lila-i masser 17 extending downwardly from the inner end of flange 16. Resting on flange 16 is a triangularI member extending upwardly and outwardly from the underframe member and having a flange 18 extending along the inclined side floor B, a flange 19 extending lrom the outer end of flange 1S to the top of flange 16, and a base flange 20 connecting the lower ends of flanges 18 and 19. This floor supporting` member includes a web 21 extending between flanges 18, 19, and 20 and this web is reinforced by a cross flange 22. A vertical flange 28 extends downwardly from the outer end of flange 20 and is secured to the underframe vertical Vflange 15. Projecting outwai'dly from flanges 19 and 28 is a web 23 terminating., f in a flange 33 which forms a continuation of flange 22 and extends downwardly within the outside line of the car and inwardly to engage the lower portion of flange 28. An enlargement 19a on flange 19 affords support for a pipe bracket 24 and the web 21 may be provided with openings 25 to receive brake rods, door operating` apparatus, or air brake or other piping. A suitable horizontal flange 25a aflords an extended bearing for such accessories. Preferably the floor supporting member just described will consist of a onepiece casting, although pressings or structural members may be interconnected to provide a similar support.

The side structure is further braced bytriangular stiffeners 26, the inner edges of which extend from near the lower edge of the side floor to the top side chord. These stifl'eners are connected to the side wall and floor and to the triangular supporting membci' just described by means of angles 27.

Both flanges of each angle 27 are bent inwardly at their Lipper ends to underlie the lower flange of top chord 9 and preferably the angles 27 are riveted to the top chord. `Between stifl'eners 26 and theend of the car l provide another stifl'ening member 29 comprising a pressing or casting of' V-shaped cross section and tapering from top to bottom and havii'ig flanged legs for attachment to the side wall. These flanges are bent inwardly at their upper end to underlie chord 9 and be secured thereto. l show fillers 13 in vertical alignment with stilfeners 29, the same providing a continuous post-like structure, parts of which are on different sides of the side wall. This result may be also accomplished by placing two angles back to back, fastening them together and to the side wall. T he tops to be bent inwardly described fer angles 27.

The straight horizontal lower end of the central part of the inclined end floor is spaced above the inner portions of the laterally inclined dumping doors, and to close the gap between these parts I provide a plate 30 attached to the underside of theadjacent underframe element and bent downwardly from the lower edge of the end floor.

As door D is inclined and crosses the horizontal plane of the lower edge of the end floor, it is unnecessary for plate 30 to extend more than partway across the end of the floor. As the rear or hinged side of the door is above the level of the bottom of the inclined floor, another gap is there pro duced between each floor and door. This gap is closed by the vertical web of the end door-stiffening member 32. 'This enables me to make the lower edge of the end floor and the corresponding portion of the underframe straight and horizontal which is an economical and otherwise desirable construction.

Each Z-bar corner post 4 is mounted on the end of an underframe side member 15 which terminates a substantial distance from the end of the car and is connected at its end to the adjacent draft sill Sil by a transverse member 35. This construction ties the superstructure and draft sills together and.

increases the rigidity of the car, at the same time unnecessary weight is eliminated by the shortening` of the car side sills.

0bviously, many of the details of my improved car structure may be varied without departing from the spirit of my invention as set forth more particularly in the appended claims. if contemplate the exclusive use of all such variations as may be made in the commercial development of my car and as are included in the scope of my claims.
