pplication @ctober 27, I931. Serial No. 5713M 12 Maine (or. its) My invention relates generally to a freight car door construction, and more particularly to a construction which includes as an element a weather strip disposed at the top of a door and formed to the shape of a trough or gutter for carrying away water, dirt, cinders, or other matter likely to beat in between the door and door opening.
The principal object of the invention is to combine a weather strip of this nature with a slid-= ing door and door frame in such manner as to produce an efiective weather seal, without requir ing a radical departure from the present practice of constructing freight car doors and door frames.
A further object of the invention is to provide a weather strip which serves not only to seal the top of the door opening to which it is applied, but also operates as a guide assisting sliding movement of the door, and as a safety catch preventing loss of the door in the event of failure of its rollers or other parts. I
Still other objects and advantages characterizing my invention will become more fully apparent from the description hereinafter of sev-= eral forms or embodiments thereof, the descrip tion having reference to the accompanying drawmgs.

Fig. II represents a vertical cross section of the same, taken as indicated by the lines II-II of Fig. I.
Fig. III represents a horizontal cross section of the same, taken in the vicinity of a door post as indicated by the lines III III of Fig. I.
Fig. IV represents a perspective view showing portions of the door frame construction at the upper left hand corner of the door opening.
Fig. v represents an enlarged sectional view similar to the top portion of Fig. II, but showing a modified form of my invention.
Fig. VI represents a similar enlarged sectional view showing an additional modification; and,
Fig. VII represents a similar enlarged sectional view showing a modification in which the invention has been applied to a sliding door of the top-hung type.
Similar reference characters are used to designate similar parts in the several figures of the drawings.
With particular reference to Figs. I and H, there is shown a portion of a box car of ordinary construction having a side wall 1 with door posts 2 therein defining a door opening, which in the example selected for illustration is closed by double side doors 3 of the bottom-hung type. The floor of the car is designated at 4.- and is shown supported upon a channel sill 5. To the chan= nel sill 5 brackets '6 are riveted at spaced intenvals, the brackets 6 supporting a track 2. Each door 3 is provided near its bottom edge with hangers 8, accommodating roller bearing rollers 9 which engage the track 7, and with suitable guide pieces 10 and 11 for keeping the door on the track. The doors 3 are of a well-known corrugated type, stiifened horizontally with corrugations 12 and vertically with corrugations 13. Conventional forms of door starters and locks are designated respectively at 14 and 15. The particular construction of the door frame and doors as outlined above represents merely an example ci a form of box car to which my invention may be readily applied, and it will be apparent from the description hereinafter that the invention may be applied to many other forms of freight car doors.
At the top of the door opening, as clearl shown in Fig. II, there is a reinforcing plate 16 to which is attached the customary Z-bar side top plate 17, the web portion 18 of which is horizontal, and the upturned flange 19 of which abuts against the reinforcing plate 16. To the downturned flange 20 of the Z-bar top plate 17, there is riveted a hood 21 which extends outwardly and downwardly, and which, where hot tom hung doors are used, is preferably provided with an extension 22 projecting around the top edges of the doors 3. The hood 21 and its extension 22 may also take the form of Z-bars.
At the inside of the downturned flange 20 of the side top plate 17, there is secured by rivets the verticalleg 23 of a weather strip 24. The weather strip 24 preferably is shaped to the form of a .l-bar and extends from one door post 2 to the other. The horizontal leg 25 of the weather strip extends outward beneath the hood 21 and terminates in an upturned flange 26, thus forming a trough or gutter along the inside top edge of the doors 3. In the example of my invention shown in Fig. II, the doors 3 are provided at their,
27 are interposed between the upturned flange 26 of the weather strip 24 and the hood 21, and the xa trough beneath the hood 21.
being a hollow metal casting havingv a rounded inner face 28 terminating in a hook-shaped projection 29, which, when the doors are closed, is
engaged by a clip 30 secured to the side edge of a the door. It will be particularly observed, as clearly shown in Fig. IV, that the trough-shaped leg 25 of the weather strip 24 extends horizontally beyond the inner faces 28 of the door posts 2," overlapping the upper ends of the hook-shaped projections 29 in such manner as to shed the content of the weather strip into the recesses 31 at the outside of the door posts 2 from whence it drains off at the car side. At the top of the door posts 2 a stifiening web in the form of a Z-bar 32 is conveniently employed as the connection between the door posts and the side top plate 1'7.
The weather strip 24 serves to collect water, snow, cinders, dirt or other matter which may beat in from the side of the car between the doors 3 and the hood 21. It also serves to collect any matter which may leak through the space between the hood 21 and the downturned flange 20 of the side plate 17. Heretofore considerable dimculty has been experienced with leakage at this point. The matter collected in the trough of the weather strip 24 is carried oil in a longitudinal direction behind the top edges of the doors 3 to the door posts 2 where it is shed clear of the door opening in the manner described above.
In Fig. if there is shown an arrangement substantially similar to that shown in Fig. H but wherein a difierent form of extension plate 27a is employed at the top edge of a sliding door 30.. The top side plate 17, the hood 21, with its extension 22, and the weather strip 24 correspond to these parts as previously described. The extension plate 2'la at the top of the door 30. is in the form of a Z-bar with its web portion 33 disposed vertically, and with its flanges 34 and v 35' projecting respectively inward and outward.
The flange 35 of the door extension plate 27a is guided for sliding movement by the depending plate 36 of the hood extension 22 and substantially bridges the gap between the door 311 and the plate 36, obstructing the passage of matter around the top edge of the door. The other flange 34 of the door extension plate 27a projects above the upturned end 26 of the weather strip 24 so as to shed matter directly into the trough thereof. In this example of the practice of my invention, the door extension plate 27d also serves as a safety catch preventing the door from falling off in the event of failure of its rollers or other parts. If the door 3a, due to injury or failure of its supporting parts, should leave the door track, the inwardly extending flange 34 will catch upon the upturned end 26 or the weather strip.
In Fig. VI there is shown an additional modification "wherein another form of door extension plate 271) is employed. The top side plate l?! and hood 21 havenot been changed, but no hood extension is used in this arrangement. The weather strip 242 is formed with an upwardly and outwardly inclined end 3'? to form Upon the door 3?) an extension plate 271) is attached, this plate comprising an angle with its vertical flange 38 guided for sliding movement between the depending leg 39 of the hood 21 and the end 3'3 of the weather strip. The horizontal flange 40 is bent downward at its end 41 to parallel the end 37 of the weather strip. This construction effectively seals the door opening and also affords a safety catch preventing loss of the door 3b. The door 3b is positively retained in such manner that it cannot be removed from the side of the car without removal of the hood 21.
In Fig. VII there is shown an example of the adaptation of my invention to a top-hung door 3c. To the side top plate 1'? a weather strip 240 of J-section is attached. The trough-shaped portion 42 of the weather strip 240 extends bee neath a relatively narrow hood 210. To the door 30 roller housings or hangers 43 are riveted. Rollers 44 are supported by pins 45 within the housings or hangers 43, and the rollers bear upon the web 18 of the side top plate 17 which serves as the door track. An extension plate 270 projects inwardly from the top of the door 30 to the space between the hood 21c and theweather strip 24c. The end 46 of this extension plate 270 is turned upward behind the depending flange 47 of the hood 210. Accordingly,
the door 30 is caught and guided for sliding 109 movement by the depending flange 47 of the hood 210. The door opening is efiectively sealed against the admission of matter around the top of the door.
The various modifications of my invention which are illustrated and described herein are merely representative of the application thereof to box car doors of different types and are not by any means indicative of the scope of changes which may be made in the form of the doors 110 and door frame construction without departing from the spirit of my invention as defined in the claims hereto annexed, which contemplates a great variety of forms of weather strips and associated parts.
