Application tiled October 17, 1911. Serial No. 655,253. y

v clear, and exact description thereof.

My invention relates particularly to cars for carrying loose commodities such as grain, coal, gravel, and the like, and it. has for its object to simplify the construction ofthe ca r as a carrier for loose commodities, to simplify and render more effective the seal and locking device for the dumping doors, to simplify and vform as a-eompoi'ient,

part of the car as 'a general freight carrier. the grain Adoor adjustable in height to meet the usual requirements, and to prevent the lodgme'nt of Water. in thel vicinity of the dump door-.lock

The invention may be 'said to consist of the Aconstruction' and several combinations andarrangementsvof parts hereinafter dcsc'ribed and pointed out in the claims.

For full comprehension, however. of my invention reference must be had to the act-.onipanying ,drawings forming a part of this specification in which similar reference cha ra'cters indicate the saine parts, and wherein:

'I

My improved car hasa pair of hoppersm'i" disposed transversely and each consisting ot :r pair of verticalwalls 2, 2, and a fixed inclined tioor member, the latter being formed'by the end portions of a plate member extending transversely to Within coniparatively close proximity of the sides of.

the car, the middle of thismember resting on the center `slland being shaped tolpresent oppositely facing angular door jambs 4, 4. It consists,ppreferably, of a pair of plates 5, 5 'constituting the fixed floor meinb'ers of the. hoppers, and the d6or-jamb portion is vpreferably formed of a separate metal plate 6 bentto the form required, the edges of all three plates being riveted together and touthe center sill as at- 7. The end edgesot these inclined floor members are attached to the bottoni edges of the vertical side Walls i?, 2 thus forming chutes, the discharge mouths of which are disposed in angular positionsvsligblly removed from the perpendici-ilar plane of the sides of the car. .Relatively small. doors 10 closethe mouths ot' these chutes, and like these months are when closed in positions inclined onlv slightly from the vertical, u flach dump door consists of the door member proper 12 with end angies lf3 to ward the door-frame formed by the fixed diagonal floor member and the vertical walls of the hopper, and a stiii'ening fiange l-t extends along the free edge thereof, the door heing hinged to the fixed diagonal tioor member and the edges of door and hopper. floor in juxtaposition and the engaging portion of the door and door frame .'propcrties, and consists of a bar 25 journaled in angular brackets 26. fastened` at the 'opposite ends of each door to 'the sidesills 2l of "the vunder-framing of the car.-

' Each .bar has'preferably forged thereon a handle 28 anda series of preferably three, presser-feet 29 adapted to bear 'upon the /oor and press ittigntlyagainst the doori jamb formed by an angle .iron 36 Afastened 2o tothe underside of the side-sills 27. One of the presser-feet isformed integrally with the handle,.an d a `bracket 30 with holes 31'V therein to receive a retainingicotter pin 32,

is fastened to the door `and affords means .25 for locking thehandle' bar, presser-feet and.

door tightly andi.` etectively closed vagainst. leakage of grain and with suiiicient strength towithstand the maximum load to which it may be' subjected when the car isv loaded 30 with Coah-ore andthelike.'.Thesepresserf feet are each preferablyvof return-bend form., as shown, to accommodate the stillening flange of the door and downwardly inclined flanges '35 presented by obtuse angleirons riveted tothe outer faces of the side sills :inthe-lower edges thereof. These langes serving aswater-sheds protecting the upper edgesof the doors when closed and the cotter pinfserves as a means for 40 sealing the door. The hinges for connectf ing thesefdischarge doors to the inclined ioor members consist of straps 40 fastened l to the doors and .floor-members and hinge rods 41 uniting them', and devices distinct from the binge proper, for providing an' effective grain tight joint between the parts held in juxtaposition by the hinge consist of coinciding flat surfaces presented by e;

flange 42 upon the Vlicor-.member and-.one ofthe faces presentedA by the' interior of a pocket 43 in the door formed by bends 44 and 4.5 surrounding the flange 4 2, the angular position of which is' such as to be cleared by the door when swinging. to open '55 position. It is to be observed that the particular arrangement et these faces prevent the rmmodity lodging thereon.

.ln order to prevent leakage of granular` +r-Gais: at the ends oi the doors.when :it pockets to receive the ilangesll of iheletter are formed in. the discharge edges el the vertical Walls of ihshoppers, ofi'- set nietes 5'.- ing riveted or otherwise rigim. eluted f. one the on" sides of these c5 wpyls al.: and parallel with the coges thereof,

for the purpose. The pockets providbd by the offset-plates and walls are justsuiiicient to receive the flanges 13 without space for the leakage of the finest granular substance such as'sand or even Hour, and the 70 same effective seal is afforded, as shown above, at the hinged .and locking edges of the door. Check chains sustain the doorsin proper position when open. ,I

AA serious defect inv cars of this type has been the misfit of the floor members and the unavailabilityof the grain-doors when required. l overcome these defects by providincr a displaceable `telescopic floor .member atdapted to displace any grain4 and the '8g like left on the center sill or other members of the nnderframe on which these displaceable floor members rest. The specific device for the purpose comprises a member 60 made up of tongue-and-groove boards 85 arranged longitudinally with relationto theV car, and fastened together by metal bands '69 'on opposite, sides of this door member* and braced by a seriesof angle-irons 61 half of the length -of each of which isv riveted ir: 90 place and the remainder sprung outslightly-jY as at 32 to accommodate thel extensible mem.- 4 I berto be presenlly further alluded to. This floor member` is hinged to the fixed floor 4members -63 of the car by means of trun- 95' nions iaste'ned tothe floor by lates 66 to 'which theyfare nweldedfsuch p ates beingriveted 'o1' bolted in place,and a plate 67 of halDf'form `with its angle disposed so v as to bear onthetop of the` side sill and against a threshold stri-p 68 when the'member 60 is raised and vthus act asa grain seal, and, at the same time, serve asa stop limiting the outward movement thereof and taking up some of the strain which otherwise would be carried entirely by the door frame in the side of the car. The trunnions are journaled in sockets beneath Athe contiguous edges of the fixed oormembers. I

in which are mounted ol'set plates :70 con-"1110 y ining the trunnions between them, the side ol the ear-body and thetop of the side sill. The :fixed iioor members are securely fastened-in place by being bolted or riveted as at 75 to the underframing. The free edges 115 of these mcmbers() are beveled to coincide andj make contact with the diagonal jambs 4, 4, on the center sill. To impart to this. displaccable floor member 60 all theproperties of a grainldoor and therefore 'enable 12o it to aii'ord a large or small loading'opening as required, it is provided with the eX- tensible member before mentioned which' i's indicated at 80 and oftrough form slidably. clasping the member G0 between it and the 125 sprung portions of the angle-iron .stifi'eners. This extensible member is for use solely as a door part and is telescoped within the limits of the niain door member 60 when the l lati-.er serves as a floor member. Y

" rima?? v door Whenitis dioppedand obtaining' a 'PIOPGI it as'part of the licor.

lVith the parts assembled as above described an elfective and strong floor is pro- -1v1ded for the ca-r as a common freight-car- `llier, -iyhen thegreatest stra-ins are exerted,

and as a graindoor is effective as a grain seal, durablep,light inweight, and always available, the -tlischarge hoppersanddoors are grain tight at allpoints and also durable andflightinweight, andthe complete structure is of suflicient strength to sustain the strainse'xerted by the heaviest cargoes of loose commodities; furthermore, an ad- `vantageous feature of the enveloping flanges 50.01' the vertical walls f the hoppers and the Hanges on the'door'enveloped thereby,

-is that it is impossible for leakage to occnr ct one finest granular loose commodity owing to the sealing enveloping flanges. The main member, 60 of the combined floor and grain-door'is held in verticalpositionV independently ofthe, extensible' section S0 and bracket, by a pair of latches 200 car- I'ied by plates 201 countersunk in the sides properties of thesef 'of the door posts.

The telescopic member is held up by bo'wspring catches 205, riveted Within recesses 207 therein, and sockets 206 in the topl of the main member of the door are engaged by these catches.

Ido not claim the locking device, the` convertible grain'- doorand floor sections 'for a car, northe features of the door jambe .and particular formation of. the

'doors for engaging 4thejambs lto' afford convertible-flat and hoppf'zr-bottom dumping car structure, as the said inventions form the subject-matter lof separate applications as follo\\'s:-Car door. locking' def vice, lifted July' 1 1, 1912, Serial No.1; 710,265. '5.0
