RAILWAY DUMP CAR.

Application filed August 27, 1926. Serial No. 131,871'.

This invention relates to railway dump cars. to-wit: cars designed for carrying lad incY in subdivided form. and which, for the sake of adaijitingr them to discharge their lading' by gravity, have certain portions of their bottom. surfaces consistingof doors movable to open or closed position at will` and other portionsthereof in the form of inclines which direct the material to the doors and insure substantially complete evacuation in response to the mere act of opening;l the doors.

One object of the present invention is to provide an improved assembly between side walls, transverse bottom frame members.,` and side wall`y inclines` whereby the said elements may stand in mutually sustaining relation each to the others. Accordingly, one feature of the invention consists in constructingr the transverse bottom frame members from channel section beams. placed with their webs vertical and their flanges horizontal, riveting' gusset plates to the backs thereof as well as to the stakes at the sides of the car. and providing` the side incline plates of the hopper bottom with vertical end flanges which overlap the faces of the channel, members opposite to those faces which ieceive the `'usz'se-t plates, as well as overlapping' the gusset plates and stakes; the outer ends of the horizontal flanges of the channel members beine' out away to receive the said flanges on the incline plates, and said incline plate flanges beine' riveted to all of said parts and constituting angle braces which stiften the lioints between them, resistance of stresses being mainly in the plane of the incline plate A further feature. incident to this part of the invention re lates to the castings which provide the pintlc bearings for the main doors and the bearers for the shafts which wind the liftinnl 'chains of doors, said casting' bein;Y produced with a pair of cheeks providing; a y pair of spaced bea rings for the doorpintle; a broad uinvardly presented face by which thev casting bears beneath and is secured to the body o f the car, terminating in a bevel throuirh which. it bears against and is riveted le incline of the hopper bottom; and

an upstanding flange through-which the casting is riveted to the vertical web ofthe oban* nel-shaped cross member; the broadV upper face beinef formedl with a troughdike depression providiner an upwardly opening;V elongatedy bearing 1n which the ehaini-wincb ingshaft lies. and a substantial opening beingr formed through the said` imstanding flange. in line with the cbain-wimlinp; shaftbearing, that facilitates introduction. of said shaft.

In cars of the type deseril'ied,` for the sake of rendering them selective as toA deposit of their lading, doors havebeen provided, specially constructed to permit of opening! in` different ways,.towit, in a manner to discharge lading,r to either side of the track at williq or between the rails of the trackR or simultaneously in both posi-v tions; but difficultyhas been experienced from the circumstance of portions of the lading" entering between hingingi-v parts and parts upon'` which they are mounted;q espeoially when the door'is hinged adjacent a hopper wall from which it projects as a guiding' surface whenl open. A further obijeet of the invention is toI provide a novel construction of door, for inst-ancei an auxiliary or secondary door, and particularly the construction of the means whereby it is mounted upon or articulated with its support, for instance, the main-door.. with a view to preventing the accumulation of lading' or foreign matter at theipoint ofarticiu lation, andy thus avoiding,rl difficulty in. bringingr the auxiliary door to its fully closed position. as well as saving;` its hinge from deterioration, In realizing this part of the invention, thesurface-forming plate ofy the door is provided. with a tailfpiece continuing; beyond the door pint-le and curved coneentrically therewith to avoid interference `with hinn'int,r action. and a platefor instance. the main door plate located between the stationary hopper' wall and the auxiliary door plate, is lapped upon the tail-piece and auxiliary door plate, 'in protecting' relation thereto. Preferably the castings are secured beneath the main1 door plate to provide pintle bearings for the auxiliary door,

and these are recessed back oit their pintle assembly of the sides and bottoms of the Cars bearings to admit the curved tail-piece ot the auxiliary door when the door is closed, thereby avoiding;` Vthe necessity tor shorten nur the tail-piece to an undesirable extent; and the taillpiece itself may be provided with ar recess ot dimension corresponding;A approximately to the thickness of the pintle castings ,in order that it may be given even a greater protecting dimension on either side ot the casting'.

ln the accompanying drawings. in which the preferred embodiment oit the several teatures of the invention is shown by way of illustration- Figure 1 is a side elevation ot those portions ot a railway car with which the inven- Jtion is immediately concerned. to-wit, one end ot the car, together with suitieient of the intermediate portion thereof to show its bottom dumping i'acilities.

Figure 2 is a vertical transverse section on the line QXMQX ot Figure 1.

Figure 3 is a detail view, on an enlarged scale. ot a portion ot Figure 2. showingthe rnotected hinn'e of the auxiliary door.

Figures 4, 5. and 6 are. respectively a top plan view, a side elevation. and an outer end view ot one ot the two castings which appear in the outer lower portions of Figure 2 and which provide the pintle bearings Jfor the main doors and the bearings for the chain winding;` shafts of the auxiliary doors.

Referring to Figure l. 1 represents a side wall. 2 an end wall, and 3 the wheels. suggesting truck location, of a railway ear ot known lrene/ml design and. tor application to which the several features ot the present invention are primarily intended. Cars oit this type have heretofore been provided with bottom dump doors 4 ot special construction. to be hereinafter alluded to. end inclines 5 iter directing;` material to the space longitudinally inward trom the trucks. where the bottom dump doors are necessarily located and lateral bottom inclines (i (Fig. 2) for directing' material laterally inward to the door openings and past the spaces occupied by the door mountines.

As will be seen in Fieure 2. cars ot this type are constructed with. a central longitudinal center sill 7 and transverse under trame .nembers 8 rest-ingr thereon and suitably united therewith, as. ttor instance. through means oi the brackets 9: which said` center sill. through that portion ot its length which traverses the dumping' area and defined by the length of the bottom doors 4l, is made lto carry center slope plates 10.

/'nderfw/mo members and Side brac-ing.

It has always been a problem. in gondola cars or cars of the type with which this in vention deals to develop secure and lasting with their bracing members, and the present invention takes advantage ot tunctional members or members concerned with the operation ot the car, .in the development of iinproved conditions in this part ot the car, by making the transverse member ot the undericrame or bearer 5l of channel section. with its web 8 vertical and its flanges 8" and 3 horizontal; rivetingn the ends oiE the said bearer to the stakes 15; riveting the `ejnsset members lt not only to the stakes as usual. but also directly to the channel meinbers 8 and preferably to the backs ot' said channel members; cutting away the ends ot the horizontal iianges 8b, S" ot the channel member. as shown in Figure 2; and causing vertical attaching tlangges (iT on the lateral hopper inclines 6 to lap upon and to be riveted directly to the web 8 and to the stake 15 while maintaining the inclination which the side inclines 6 are required to have in service, and therefore7 in a position which causes the inclined plates to serve as e toctive angle braces between the sides and the transverse underffraine members, and. in such service. to receive stresses which arcI largely in the planes of the plates and theretore in the direction to be resisted most ettectively.

ln ears ot the kind describi-al. it hasl herototore been proposed to mount doors. such as el. upon pintlos. 4such as .located beneath the side lnmper-inclinns andA to this end. provide castin!` i7 in which to mount said pintlcs and. incidentallyn when doorsel have been of the type employing doors 'l pivotcd on the main doors at i9. it has been propoffied to dcsinn the castings IT so that they will atlioid hearings tor shai'ts Q() upon which to wind chains 2i vl:"or control et said auxiliary doors. rl`hc present invention iinproves the design tor the castingl l? hv liormiiisr it with a broad bcarinfl' plate il" by which it hears beneath thc hodyot the car. tor instance. the bottom niare'inal nlenibcr 2l ot the with an upwardlv prcsented intermediate tlane'c lil by which the casting' is ri vetcd to the hach ot' thc web S olE the undcrtranic cross nicnibcr ti: with a beveled henri. tace le' throufrh means ot which the ca 'n.ej meets and in riveted to the side incline (i or the guard picco 2;). as shown in Figure i2: with two cli-eel( incinbers iT'h depondinn iti-ora tho top plate and constructed with al. nal opcninnjs that prf vide pint-le hearine l"': with ti'in'n-'rerso doprcssion Q0 in the side Yl z top plate 17, proviciiur an upwardly.v opening hearine' -tor sha .t 52h: with the two transverse wolmobiliersI il". l7f. which are intein-al with tht` lop plate 17a and cheek member 17d, and in planes parallel with and adiacent the respective bearings la 20a to strengthen them. and with lll) a' bracket webV 175 dependingy in a central `inner tree end controlled by shaft 23, the

auxiliary door i8, articulated with the main door at 19', wliiel'r is about'the point where the center inclines lll meet the auxiliary door. At such point7 dilliculty has been experienced as a result ot lading)v entering); oe,- tween the lixed and movable parts ot the articulation, also trom deterioration oit the hinge. To remedy this detect, the present invention provides the bottom plate ot the door 18 with a tail piece 1S extending; inwardly beyond the pintle it) to an extent which adapts it to effectively shield the pintle and its bearing', said tail piece lit-ang.; curved concentrically with the pintle in order not to interfere with the swinging; ot the door; and to-malte vthe shield still more etl'ective, the plate Il" oit the main door l is continued outwardly in overlapping` relation to the plate of the auxiliary door 1S and the tail lpiece 187 and to a point ot intersection with the center incline l0, so that', as shown more clearly in Figure 2l. the articulating connection ot the auxiliary door is thoroughly protected. This protection is etl'ected not only against lading or residue thereof or foreign matt-ertraversing the con ter incline l() when the auXiliaiy door is `open to the dotted line position otl Figure El,

but it is equally effective when the main door l is open, as a wholer` upon its pivot Li, as by turningf the shatt 23. and in which position lading will traverse, the ent-ire surtace ot' the main door a, made up in part ot the auxiliary door 1S and the main door plate t", since at this time. the auxiliary door lSQheltl tightly to its closed position` is bearing: snugly against the lapped endet the plate 4th.
