Fig. 2 is a horizontal section taken on line 2-2 of Fig. 1, a portion being broken away.

Fig. 3 is a Vertical section taken on line 3-3 1 of Fig. 2.

Fig. 4 is a horizontal section similar to Fig. 2 showing a modification of the invention.

Fig. 5 is a vertical section taken on line li -5 of Fig. 4.

Referring to the embodiment of the inven- Claims. (CI. -26);

tion illustrated in Figs. 1' to 3, inclusive, the numeral l3 designates a conventional Z-shaped side plate, the upstanding flange of which is broken away. The side plate includes a depending flange Ii to which the upper ends of door posts are fastened in any desired manner. The forward door post only is illustrated and is designated by the reference numeral l2.

A substantially J-shaped header i3 is carried by the side plate ID. The header embodies a vertical attaching flange M from the lower end i of which a horizontal flange l5 projects outwardly. The flange 15. is turned upwardly to provide a flange 16. The header is extended sufficiently beyond the door .posts and is secured to the depending flange H of the side plate and to the doorv posts so as to serve as a reinforcement for the ear across the door opening and as a track for door lift mechanism hereinafter briefly described. Additionally, the header serves to trap foreign matter which might otherwise flnd its way into the car through the door opening and to this end the upstanding flange iii of the header cooperates with a member carried by the car door to prevent any foreign matter from being blown over the flange and into the car as hereinafter explained.

The door opening defined by the side plate, the door posts and thefloor of the car (not shown) is controlled by means of a door ll. This door embodies ,a metallic panel 18 ofiset outwardly adjacent to thefront and rear vertical edges thereof asindicated at l9 and 23;

The margins ofthe p nel are suitably reinforced. The front vertical margin is reinforced by means of a relatively sturdy member 2|. This member is formed with a flange 22 which overlies and is secured to the panel as by means of rivets 23. The reinforcingmember 2! also embodies a'web 24; a forwardly extending flange 25 disposed substantially in the main plane of the panel and a-flange 26 extending outwardly at right angles to the'flange 25 and lying at the forward edge .of, the door. Backing plates 2? and 21A disposed'substantially in the main plane of the panel are secured thereto along one margin and to the flange 25 of the reinforcing member along the other margimthereby providing a substantially box section adjacent to the forward edge of the door. 1

The upper margin of the panel I8 is similarly offset as indicated at 28. This margin of the panel is reinforced by means of a member 29 which is substantially'W-shaped in section. The reinforcing member ,29 embodies a 7 depending flange 30 overlappingand'secured to the panel, an inwardly-extending web 3|, an upstanding flange 32, and an inwardly directed flange 33. A backing-plate 34 is secured to the panel l8 substantially in the main plane thereof and to the flange 32 of the reinforcing member and cooperates therewith and with the panel and backing plate2'l to form aibox section.

The door is adapted to be -frictionally supported upon a track (not shown) fastened to the car below the-door opening. -Liftmechanism, designated generally by thereference numeral 35, is secured to the upper; portion of'the door for the purpise of elevating; the door and sup; porting it upon anti-friction means upon the header to permit movementof the door in opening and closing directions.

With reference to Figs. 2 and 3 of the drawings, it will be observed that the inwardly extending flange 33 of the door reinforcing member 29 lies vertically; above theheader i3 so as to1cooperate therewithin .the securement of a weathertight door. A stop 36 of conventional cross section is also illustrated in these figures of the drawings. This stop embodies a substantially channel shaped portion 31 which receives the front vertical portion of the door when it is closed. A flange 38 extends inwardly from the channel-shaped portion 31 and terminates'in an attaching flange 39 which is disposed parallel and secured to the frontdoor'post {2. Q

Prior to applicants invention the front door stop 36 continued upwardlyto the door retaining bar 43 which, as illustrated in Fig. 3 of. the drawings, is Z-shaped insectionandembodies an upstanding flangefil secured to the depending flange ll of the side, plate; an outwardly extending web 42.,an'd iaidependingi flange '43 spaced outwardly of the header Jl3." With this relationship between the front stop and the retaining bar, it will beapparent thatthe header, in the prior constructions could not extend forwardly beyond the flange 38 of the front stop and it is customary to terminate the header at this flange. Moreover, in the prior constructions in order to per-- mit the door to close fully, it is necessary to cope the inwardly extending flange of the top door reinforcing member adjacent-to the; forward yer-- tical edge of the door so that this flange would not strike against the inwardly extending flange- 38 of the front stop and preyentzthe door from being fully closed. This coping of the inwardly extending flange of the top door reinforcing member, however, provides a substantially direct opening between; the: upper frontcorrier of the door an'dithefront stoppermitting. dust, Cinders, rain, snow -andthedike, to find their way into the car through the door opening; T

The instantinvention eliminates this opening and substantially improves the weathertightness of the upper front corner of; the-door. As more clearly disclosed:in liigs;- 1; 2 and-30f the drawings, the front -doonstop -iififiis: terminated below and adjacentto-theheader Id. The header is extended forwardly beyond the front stop and I the flange 33 of the doon reinforcing: member 291's permitted toextendficontinuouslysubstantially to the frontvertical edgeaof the door. 7 K

To close the-opening abovethe header provided by this construction a plate member- 44 is utilized. This member isshownmore clearly in Fig. 3 of the drawings and embodie's an outwardly and rearwardly directed flange, 45 which is similar to and disposed upon-a: corresponding flange of the channel portion 31 ofthe front stop. The member 44- is also providedwith an inwardly extending flange dfiwhich i's disposedupon the web of the channel shaped portion-3 of the front stop and extends-inwardly of the attaching flange of the header to :w-hioh itis secured as by means ofwelding; The-inwardly extending flange as, as =moreclearly-shown: in=Ei'g; 3fof the drawings, is coped to clear the upstanding-flange it of the header. At-itsupper portionthe-member dd extendsto the depending=flange 43 f theretaining bar 40-. inwardlyof thedepending flange 4'3 the flange-46 of the=membenfi-ifollows the inner contour of thB dGOI-a retaining bar and extends continuously==downwardly therefrom-to the cutwardly extending flange I 5 of the header.

It willbeapparent-from the foregoing construction that the inwardlyextending flang as of the member'fl closes: the header and serves as an abutment= flange for the door above the door stop andthat the inwardly-extending flange 33 of the door reinforcing member 29- extends continuously to the-flange 46 which-it is adapted to abut when=the dooris closed; The opening in the priorconstructionsprovided-by the cope in this-inwardlyextending fiange of the to door reinforcing member is' accordinglyeliminated and a materially improved 'weathertightconstruction is afforded for-theupper; corner'of the door.

Another embodiment of the invention is illustrated inFigs; 4 and5 ofthe drawings. In this embodiment the header IS terminateS-at the inwardly extendingfl'ange 38 of the front stop as indicated'at-dli? In order to close the header 13 a member 49 is utilized? -The portion of this member which extends'upwardly above the front stop 36 embodies a-flange ifl similarto the flange 45 of the firstdescribed embodiment of the inventioncand an:inwardly:directed flange Eiwhich is similarto; thezflangealfi'rhereinabove described as indicated at 52 with the exception that the cope formed in the flange 46 for the-purpose; of receiving the upstanding flange Hi' of thehea-der l't iseliminated. Moreover, the flange 5| is extended downwardly to provide a flange extending fromthe channel-shaped portion 37 of the front stop to the wall of the car. In both embodiments of the invention the inwardly extending flanges of the

closuremembers

44 and 49 are in alinementwith thewebidl of the front stop.

By terminating the header l3 at the inwardly extending'flange: 38gof the front stop, it follows that theheader is spaced from the inwardly extending flange 5! of the, closure member 49, It follows, moreover, that any foreign matter which may be collectedinthe header maybe discharged outwardly of the door. stopint'o -the:space formedbetween the inwardly extending fl'ange 38 0f; the door. stop and: the inwardlyextending flange 55 of the closure member 49; Byextending; the flange 52 of the-closure member-dd-downwardly, as more clearly shown in Fig. 5"-of the-drawings, the open end of the header l3'is-protect ed;-

In all otherv respects theform-o'f;theinvention illustrated in Figs; 4 and i 5- of f the drawings enibodies the construction of-the forn'i-ofthe invention illustrated in Figs: 1', 2, and 3fiof 't'hedrav ings.
