10 Claims. (Ci. 20-42) This invention relates to railway box cars and more particularly to a door header construction for the doorways of such cars whereby weather, light and foreign matter are prevented from entering the cars from over the doors.

The principal object of the invention is to provide a box car door header so formed as more effectively to prevent weather, light and foreign matter from passing over the top of the door and entering the car through the doorway.

An important object of the invention is the provision of a door header member comprised of a formed section having an outstanding flange adapted to baffle the elements at the top edge of the car door from entering the car and to deflect any elements passing the flange into the formed section.

A further and more specific object of the invention contemplates a car door header in the form of a trough at the inner side of the door and having an outstanding flange overlying the door top edge adapted to baffle the top of the door against the entrance of foreign matter and to deflect matter forced past the flange into the trough and direct overflow from the trough over the door to the outside.

A still further and specific object of the invention is realized in the disposition of the bottom wall of the trough shaped header at an inclined angle such that any accumulation of water or the like is directed away from the interior of a car and having drain holes at the ends of the trough to maintain the water level below the point where it might leak into the car.

Still another object of the invention is the provision of a combination door closure, battle, and guide and holder unit adapted for application to the top of a box car door at the trailing edge whereby the door is guided and held in position and Weather, light and foreign matattained by the door header structure and arrangement illustrated in the accompanying drawings, wherein:

Figure 1 is a longitudinal sectional view through a box car side door opening illustrating the relationship between various members of the car structure and the sliding side door when the door is in closed position;

Figure 2 is a transverse sectional view through the top portion of the side door opening taken on line 2-2 of Figure 1 illustrating the door header, the top portion of'the door and a portion ofthe car roof structure;

Figure 3 is a view similar to Figure 2 except taken on line 33 of Figure 1 and having the door removed illustrating the relationship between the spark shield member and the door top retainer;

Figure 4 is the same as Figure 3 except showing the door in closed position and illustrating'the combination door closure, baflle and holder unit applied on top of 2,974,376 Patented Mar. 14, 1961 Figure 5 is a fragmentary perspective view of the front top corner of the door opening illustrating various members of the car structure as arranged for the leading edge of the door;

.Figure 6 is also a fragmentary perspective view the same as Figure 5 except taken at the opposite rear top corner of the door opening and illustrates the car structural members as arranged for the trailing edge of the door, and

Figure 7 is a fragmentary perspective view of the door assembly illustrating the top corner at the trailing edge of the door.

The invention atfords a car door header structure which achieves a weatherproof seal along the upper edge of the door andefiectively baffles the door top edge against the passage of light or foreign matter into the car. The header structure is comprised of a generally trough shaped section including an inner flange adapted to be secured to the side plate of the car, a bottom wall disposed at an inclined angle sloping outwardly and downwardly from the inner flange and an upstanding outer flange in proximate relationship to the inner face of the door adjacent the door top edge and having an outwardly directed terminal flange overlying the door top edge with the door having a generally outwardly disposed flange underlying the flange on the header. The door top retainer on the car overlies the header and door top edge to obtain a seal arrangement at the top of the door such that weather forced past the baffle flange will be de flected into the trough shaped portion. The generally horizontal terminal flange of the header by reason of its overlying relationship to the top of the door will cause any overflow of foreign matter from the trough to be discharged over the top of the door and beyond the outside face of the door. The outwardly and downwardly inclined bottom Wall of the trough directs water or the like that might accumulate in the trough away from the interior of the car and drain holes in the vertical termination walls at each end of the trough drain the water to the outside of the car thereby maintaining the water level in the trough below the point where it might leak into the car. The combination door closure, baflle, and guide and holder unit of the invention achieves a weatherproof seal on top of the door at the trailing edge when the door is in the closed position and eifectively prevents the passage of weather, light and foreign matter into the car. The unit is comprised of a closure plate portion horizontally disposed on the top edge of'the door, two upwardly extending baflle flanges and a door guide and holder pad extending downwardly on the outer surface of the door.

In the drawings 10 represents a railway box car having a side wall 12 and a roof 13 with a longitudinally extending side plate 14 operatively disposed at the juncture thereof. The side plate member includes a depending flange 15, a generally horizontal web portion 16 and an upwardly and inwardly directed flange 17 upon which the roof is supported and secured. The side wall 12 is provided with an opening or doorway 18 which is adapted to be covered and uncovered by a sliding side door 19. A door top retainer 26 is secured to the depending flange 15 of the side plate and is provided with an outwardly extending web portion 21 above the top of the door and an outer depending flange 22 disposed outwardly of the door top edge structure. The retainer extends for the full width of the door 19 and its movement in uncovering the door opening 18 and is secured by riveting to the flange 15 of the side plate through the medium of upstanding flange 23. The side door 19 is provided with a door top edge framing member 24 which has a generally outwardly directed upper flange 25.

Front and rear door posts 26 and 27 respectively, de-

fine the sides of the door opening 18 and are secured at the top to side plate 14. A front stop 28, secured to the front door post, and a spark strip 29, secured to the rear door post, act to provide weather sealing closures for the leading and trailing edges of the door in its closed position. A leading edge framing member 30 on the door and a door trailing edge framing member 31 cooperate with the front stop and spark strip to effect the weathersealed closures. An angle shaped baflle plate 32 supplements the spark strip 29 in weatherproofing the trailing edge of the door. It is to be noted that the door front stop 28 and the door top retainer are so interrelated at the front top corner of the door opening that the entrance of light is precluded at this location in the closed position of the door 19 with the door leading edge member 30 entered in the front stop 28 and the door top edge member 24 disposed under the top retainer 20. A closure plate covering the top of the leading edge member seals the open top end of this member.

At the top trailing corner of the door special provi sion is made to seal this area against the entrance of light when the door is closed. An integral unit 35 comprised of a closure plate portion 37, two upwardly extending baflle flanges 38 and a door guide and holder pad 39 overlies the flange 34 on the door trailing edge member 31 and covers the opening between flange 34 and the return flange 36 embracing the spark strip 29. The unit 35 is secured to the door trailing edge framing member 31 by welding and moves with the door as an integral part thereof. The door guide and holder pad 39 cooperates with the inwardly spaced portion 40 on the inside face of the depending flange 22 of the top retainer 20 for guiding and holding the door 19 in position during the final closing movement of the door. Spaced upstanding baffles 38 on the unit 35 terminate in spaced proximity to the under side of the web 21 of the top retainer 20 and act as baflles against the entrance of light or weather at this point to seal this area when the door is closed. It will be seen that the closure plate portion 37 of the unit 35 with its associated baffles 38 in the closed position of the door overlies the rearwardly extending flange of the spark strip 29 and closes the top of the door trailing edge framing member 31 between the flanges 34 and 36 so that weather is prevented from entering over this point and the passage of light either directly or reflected is blocked from entering past this point into the door opening.

Extending entirely across the top of the door opening 18 a door header 41 is provided which effectively weatherproofs the entire top edge of the door 19 to prevent the entrance of light or foreign matter throughout the full width of the door. The header is in the form of a trough at the inner side of the door and has an upstanding inner flange 42 engaging the inside face of the depending flange 15 on the side plate and secured thereto by riveting. A sloping Web portion 43 extends generally outwardly from the flange 42 under the bottom edge of the flange 15 and an upstanding outer flange 44 completes the trough like shape of the header. The flange 44 is disposed in proximate relation to the inside face of the side door adjacent the top edge thereof to provide a close Weathersealing relationship therewith and at the top of this up standing flange a horizontal flange 45 extends outwardly in overlying relationship to the flange on the door top edge framing member. The header extends continuously between the front door post 26 and the associated front stop 28 and the rear door post 27 and its associated spark strip 29. At the leading edge of the door the header is fitted to the front stop and welded and the closure plate on the door leading edge member effectively prevents any light or weather from entering upwardly through the door edge member and over the header flange 45. At the trailing edge of the door the header is fitted against the spark strip 29 and welded and the closure plate portion 37 of cast unit with the batfles 38 effectively pre-- acreagevent the entrance of light and weather over the header flange 45 at this corner. The cast closure unit 35 thus seals off any opening that might otherwise occur between the header and the top retainer and overlies the top of the rearwardly directed flange 34 on the door trailing edge framing member 31 to provide an effective barrier against the entrance of light and moisture or other foreign matter. The upstanding bafiles 38 on the cast closure unit 35 which is mounted on the top of the door trailing edge member '31 approach in the direction of the header flange 45 as the cast closure unit enters over the rearward flange of the spark strip and in the final closed position of the door the two baflle flanges afford a completely weatherproof condition at the top rear corner of the door in conjunction with the overlying top retainer.

The outstanding flange 45 on the door header acts as a baflle that will deflect the elements and provide an eflicient seal along the top edge of the door to prevent the entrance of light and foreign matter over the door 19 into the car. If water or snow or the like should be forced past this baflling flange they will be deflected into the trough portion of the header and if the trough becomes filled the outstanding flange overlapping the door will serve to direct the overflow to the outside of the door and eliminate any possibility of overflowing into the car. It will be noted that the trough of the header 41 is continuous between the front stop 28 and the rear spark strip 29 entirely across the full width of the door opening 18. At respectively opposite ends of the trough portion an opening 46 is provided in the front stop and spark strip which permit drainage of any water accumulation in the trough through either end to the outside of the car. These openings are disposed adjacent the lowermost point of the trough where the sloping web 43 joins with the upstanding flange 44 so that the trough normally does not accumulate any water above the level of the point where the sloping web 43 joins with the inner upstanding flange 42. In practice opening 47 formed by the offset in the side door posts 26 and 27 at the bottom of side plate flange 15 is sealed with caulking material. The header is disposed under the top retainer 20 and the outermost flange 22 of the retainer extends downwardly past the outstanding flange 45 on the header and the outwardly directed flange 25 on the door so that any matter which may blow upwardly under the retainer will first encounter the door flange 25 which will check further progress of such matter and if the force behind the matter is such as to blow it past the flange 25 then it will be deflected over the header flange 45 into the trough and be prevented from finding its way over the door into the car.

From the foregoing it will be seen that the invention provides a complete baffle to the entry of foreign matter over the door into the car.
