It will be understood that the car is constructed so as to provide a nun'iber of dumping openings on opposite sides of the centersill, these openings being normally closed by hinged bottom sections or doors which are manipulated by apparatus which forms no part of the present invention and which, therefore, has been omitted from the drawings. This invention concerns the construction of a door suitable for use in a car of this type, or with other dumping cars where similar conditions prevail.

The door consists of a sheet metal panel 15 preferably, although not necessarily, composed of ay single sheet of metal. The door sheet, as it may be termed, is formed with a kcentral corrugated portion 16 and at one edge is hinged to the center sill 10 (the hinges being indicated at 17). marginal portions-18, 16 of the door sheet and the sider marginal portion 19 thereof `which bears against the under side of the inturned part 20 of the side sheet 12 are in the same plane, thatis, the original plane of the sheet before it is pressed. The corrugated portion 16 of the sheet is formed by pressing therein, in parallel arrangement, a plurality of ribs which alternately project above and below the original plane of the sheet. Those projecting upwardly preferably have their crests in a plane at the level of the cross bearer cover plates 14 and the intervening. center sill cover plates (not shown). v.The hinged margin 22 of the sheet is depressed to the level of the bottoms of 4the. depressed corrugations. this arrangement any moisture will drain olf along the depressed edge 22 of the plate instead of being trapped as would be the case if both ends of the corrugations were below, the level of the adjacent uncorrugated margins. The corrugations are lmade to terminate within the edges of the sheet so that they will give it rigidity. l The configuration 'of the sheet as shownfalso adapts it to ht snugly in place underthe center sill and side sheets. The center ysill is shown as consisting in part of T-beam 23 and inA order that the door may project under the upper flange of this T- bearnthe extremitiesof the marginal portions 18 adjacent the center sill are"de pressed, as indicatedat 24, to the level of the marginal portion 22 ofthe sheet'. To give additional strength and rigidity to the door its edges are formed with downturned flanges 25. In addition a rigidifying structure is provided for. the lunder side of the door comprising angle bars 26 running parallel with the corrugations and secured by rivets 27 to the marginal portions 18 of the door'and tothe flanges 25, with the interpositin of spacers 28, by rivets 29, together with a'Z-bar 30 secured to the members 26 The end and to the door sheet and extending across the ends of the corrugations and angle bars 3l. near the opposite edge of the door which are riveted to the door at suitable intervals.

I claim:

l. In combination with a railway ear having a dumping openingl in the bottom, a sheet metal door to close the same formed with strengthening corrugations which terminate within the edges of the door sheet, said door sheet being formed so that portions of the corrugations project below the plane of adjacent uncorrugatcd parts of the sheet. while the corrugations at one end are cntirelyab ve the uncorrugated marginal part of the sieet adjacent thereto for Llrninagi` purposes.

In combination with a railway cal' having a door opening in the bottom, :i sheet metal door to close the same formed with a plurality of corrugations extending across the door sheet between opposite edges, the portions of the corrugations adjacent one of said edges projecting below the adjacent marginal parts of the sheet while the opposite ends of the corrugations stand substantially above the uncorrugated part of the marginal sheet adjacent thereto.

3. In combination with a railway car having a door opening in the bottom, a sheet metaldoor to close the same formed with :t plurality of parallel corrugations extending 'across the door sheetbetween opposite edges at right angles to said edges, the portions of the corrugations adjacent one of said edges projecting below the adjacent marginal parts of the sheet while the opposite ends of the corrugations stand substantially above the un'corrugated part of the marginal sheet adjacent thereto.

4. In combination with a raihvay car hat ing a dumping opening in the bottom, a sheet metal door to close thc same formed with a depressed portion which extends to one edge of the door sheet, said depressed portion having pressed therein corrugations upstanding therefrom which terminate within the edges of the sheet.

5. In combination with a railway car haw ingga dumping opening in the bottom, n. sheet metal door to close the same formed with a depressed portion which extends to one edge of the door sheet, said depressed portion having pressed therein (.orrugations upstanding therefrom which extend toward but terminate short of said edge.

6. In combination with a railway car having a dumping opening in the bottom` a sheet metal door to close the same formed with a depressed portion which` extends to one edge of the door sheet, said depressed portion having pressed therein a plurality is Closed and the holloxrs of which merge' into the snrfaeeoi" described.

. 19.V In eombination with a railway kear liavingalnmping opening, a sheet metal door to close the same formed With stillening Corrugations, and With marginal portions the sheet7 l'or the purpose adapted to rigidity themargins of the sheet;

said corrngations and marginal portions being `so proportioned with' relation to eaeh -formed on said'panel adapted to be snpported substantially llush with the flooring of theear when the door is closed.

2l'. door strneturelfor railway oars of the dumping type comprising a sheet niet-al vpanel Jformed with corrugations which project below ythe plane of certain adjacent uncorrugated parts of the sheet lWhile the deepest parts ofsaid corrngations are flush with an nneorrngated part'ol said sheet.

22.v A door structure for railway cars of the dumping type comprising :i sheet melal panel formed With a depressed portion which extends along one edge of the door leaving marginal portions along the other three edges which are in a higher plane7 said panel being formed `with a plurality or' pai'- allel eorrngations which project entirely above the said depressed margin of said panel.

A door structure for railway ears o'l" the dumping type, comprising a sheet metal panel provided with rigidifying marginal.

portions and with a plurality of eorrnga` tions extending across said panel, the corrugations at the center ot the panel being of greater length than the eorrugations at the sides thereof.

2l. A door structure for railira)r` rars ol the dumping type, comprising a sheet mel al panel. provided with marginal portionsI whii-li extend along three edges of the panel al a higher plane than the marginal portions extending along the other edge of said panel. and formed With eorrugations of snbstan tially equal length which project entirely above the lower marginal portion el the panel- GARTI-I G.
