(Cl. Ztl-26) 16 Claims.

This invention relates to sliding car doors and primarily to door constructions for preventing rain, snow, dust, cinders and the like from entering the car.

It is an object of this invention to provide sliding doors for cars, particularly of the house type, so constructed and associated with the car wall as to substantially exclude the entry of rain, snow, dust, cinders and the like from these cars.

A further object is to provide sliding car doors having substantially rigid parts and to associate said parts with substantially rigid members on a car wall to prevent the ingress of foreign matter into the car.

A further object is to provide sliding car doors constructed and associated with `the car wall so as to prevent damming of water, snow, dust, cinders and the like directly against the rear edge of the doors.

A further object is to provide sliding car doors, the rear portions of which are constructed and associated with the car wall to present offset transversely extending baiiies for trapping and disposing of foreign matter exteriorly of the car.

Other objects of the invention will become clear as the description thereof proceeds.

In the drawing forming part of this specification:

Fig. 1 is a fragmentary elevation of a house car and a slidingV door thereon embodying the invention.

Fig. 2 is a horizontal section taken on line 2'-2 of Fig. 1.

Figs. 3, 4, 5, 6, 7 and 8 are horizontal sections similar to Fig. 2 illustrating other embodiments of the invention.

Referring to the drawing and particularly to the embodiment of the invention illustrated in Figs. 1 and 2, the reference numeral I0 designates generally a metallic sliding door for a railway house car, a portion of the Wall of which is shown at II. The construction of the rear portion of the door, the balance of the structure of which is not essential to the description of the instant invention, embodies a metallic panel I2 having horizontal corrugations one of which is illustrated at I3. The` panel is offset outwardly as indicated at I4 to provide a flange I5 spaced laterally outwardly of the main plane of the panel.

A relatively sturdy angular reinforcing member I6 is utilized to reinforce the rear portion of the door I0. The reinforcing member I6 embodies a vertical flange I'I overlapping and secured to the flange I of the metallic panel. 4A flange I8 extends inwardly fromr the flange Il.' The reinforcing member IIi is then terminated rearwardly in the formof aflange I9 disposed substantially in the main plane of the panel. From the flange IS a flange 2 0 lying at substantially a right angle to the wall II is directed inwardly across the main plane of the panel. v

A backing plate 2| extends across the space between the outwardly offset portion I4J of the panel and the inwardlyV directed ange I8 of the reinforcing member.A This plate is secured to the panel substantially in the main planethereof and to the rearwardly directed flange I3 of the reinforcing member. 1

Secured to the latterflangeM of the reinforcing member by means of rivets 22 which fasten the backing plate thereto isa metallic sealing strip 23 which is substantially Z-shaped in'section. The sealing striphas a forwardly and `inwardly directed flange 24 spaced inwardly from the backing plate 2l and adapted to cooperate with a spark strip 25. The spark strip is adapted to be secured to an outwardly extending flange 26 fastened to the door post 21. A

As appears more clearly from Fig. l of the drawing the inwardly Ydirected. flange 20 of the reinforcing member I6 is bent rearwardly from its normal position so as to provide a flange 28 lying at an obtuse angle to the Wall II. The bending of the flange 2U begins at a poi-nt above the bottom of the door so that it serves as a striking member adapted to engage a back stop (not shown) to limit opening movement of the door. Where aback stop is utilized for the upper rear corner of the door the construction of the reinforcing member will be the same as that above described.

A substantially channel shapedl member 29 is secured to the post 21. This member comprises a web 35i disposed outwardly and substantially parallel to the Wall and oppositely extending flanges 3| and 3'2. These flanges extend from the web 29 toward the4 walland are disposed at an obtuse angle to the Wall. The anges 3i and 32 extending along the wall II as indicated at` 33 and 34 are fastened thereto in any desired manner. The extension 33 of the flange 3| is b ent to provide an outwardly extending flange 35 disposed preferably at a right angle to the wall.

From Fig. 2 of the drawing it will be apparent that; the angularity of the flanges 2,8 and 3| rela'- tive to the wall is the same, which is preferred, and that the flange 28 lies forwardly of the flange V3-I when the door is closed. The described relaspect to the wall avoid damming of foreign :rnat-Y ter blown toward the rear edge of the door. foreign matter, to the contrary, is directed outwardly so that despite the termination of the flanges 20 and 28 short of the channel shapedV member 29 very little foreign matter is blown between these flanges and the channel shaped member. Such foreign matter as may find its Way beyond the flanges 20 and 28 will encounter the flange 35V and be prevented from entering the car. The construction thus prevents damming of foreign Vmatter and provides a series of transversely extending baiiles which in the preferred construction are offset relative to each other.

In the embodiment of the invention illustrated in Fig. 3 of the drawings an additional baffle is provided. In this embodiment the flange 20 lies substantially at a right angle to the Wall throughout its entire height. A separate flange 35 is .secured to the'ange 20 as by means of welding so as to lie at ancbtuse angle to thevcar Wall. The flanges 20 and 36 are braced by means of plates 31 preferably welded -to the flanges. By this construction both the flangesV 36 and 2l! are effective as baiiles forpreventing the ingress of foreign matter into the car.

In Fig. 4 ofthe drawing the invention is illustrated applied to a different type of door 3B. This door comprises afmetallic panel 39 formed with horizontal corrugations, Aone of lwhich is shown at 40. These corrugations merge into avertical corrugation 4| beyond which the panel extends as indicated at 42. The vertical corrugation is bridged by means of a backing plate 43 which is secured preferably by means of rivets to the panel on opposite sides of 'the-corrugation. A sealing strip 23 is secured to the inside of the panel extension 42 and is adapted to cooperate with a `spark strip 25 as hereinabove described.

A reinforcing member 44-is disposed upon the outside of the panel extension 42 and is fastened Athereto and to the sealing strip 23 preferably by :meansl of rivets. The reinforcing member 44 is preferably formed from a structural T and is so disposed that the head flange 45 serves as the attaching flange. The stem 4'5 of the T extends inwardly'toward the car wall I l and the remaining head flange 41 is deformed so as to lie at an obtuse angle to the wall. The stem 46 and the head flange 41 are braced by means of plates 48 preferably welded to these anges.

As inthe -two previously described embodiments vof the invention the baille provided by the stem 46 lies rearwardly of the flange 35 of the channel lshaped member 29. Moreover, the relationship :between the flanges 46 and 41 of the reinforcing member and the flanges of the channel shaped wall member'29 is substantially the same as the previously described relationship between the reinforcing members and the channel shaped memloer 29 of the first two embodiments of the invention.

1 v In Figs. 5 and 6 of the drawing the door structures illustrated in Figs. 3 and 4 are shown asso- Such Y elated with a modified form of wall channel shaped member for preventing the entry of foreign matter into the car.

With particular reference to Fig. 5 of the drawing, it will be seen that the door post 49 differs structurally from the door post 21 and presents a flange 5U extending toward the door opening. An angle member 5I arranged with one of its flanges extending outwardly from thewwall is fastened to the door post 49 as by means of rivets 52 passing through the flange -53 of the angle member 5I and the flange 5i) of the door post.

y To the outwardly extending flange 54 of the angle member the post strip 25 is secured. The metallic sheathing 55 of the car wall is fastened to the flange 50 of the door post 49 in any desired manner.

The modified wall channel shaped member 55 is secured to the Wall by welding or riveting through its web 51. This web carries a flange 58 adjacent to the door opening and a flange 59 remote from the door opening. The latter flange, as clearly appears from the drawing, extends outwardly at an obtuse angle to the wall. The flange 59 is reinforced by means of plates 60 Welded to the web 51 and to the flange. These plates serve additionally as guide ribs for the door to prevent the flange 36 of the door reinforcing member from fouling the flange 59 in the opening movement of the door.

In the form of the invention illustrated in Fig. Y

6 of the drawing a door post 6I provided with a flange 62 extending rearwardly from the door opening is utilized. To the latter ang'e the metallic sheathing 63 of the car wall and a post protection angle 64 are fastened as :by `means of rivets 65. The outwardly extending leg of the post protection angle carries the post strip 25 which is preferably riveted thereto as illustrated.

A channel shaped member 66 substantially similar to the channel shaped member 53V is utilized with the door 38 having the T-shaped reinforcing member 44. The web 61 of the channelshaped member 66 which is somewhat longer than the web 51 of the channel shaped member 56 is secured to the metallic sheathing 63 in any desired manner. The web 61 carries a flange 68 disposed adjacent to the door opening and a flange 69 remote from the door opening. The latter flange lies at an obtuse angle to the car wall. Reinforcing and guiding plates 1li similar to the plates 60 are employed in this embodiment of the invention.

It will be clear from the foregoing description of the embodiments of the invention illustrated in Figs. 5 and 6 ofthe drawing that they provide flanges which serve to baffle any foreign matter tending to enter the car around the rear edge of the door. vThe structure of these embodiments, moreover, prevents damming of water or other foreign matter directed toward the rear edge of the door and provides for the disposal of such matter outwardly of the door opening.

The construction illustrated in Fig. 7 of the drawing eliminates the separate channel shaped member 29 utilized in the embodiment 'of the invention illustrated in Fig.- 2 of the drawing. In the considered embodiment the' door post 21 lis formed with an integral channel shaped portion 1l. The web 12 thereof is disposed outwardly of the car wall and is connected to the post by means of the obtusely arranged- flanges 13 and 14. A plate member 15 is preferably utilized. This plate member extends across the channel portion 1l and is fastened on opposite sides thereof in any desired manner. There is thus provided a box section which affords reinforcement for the door post.

vAn additional baffle comparable to that provided by the outwardly extending flange 35 shown in Fig. 2 of the drawing is employed in the considered embodiment of the invention. This baille is afforded by the outwardly extending leg 16 of an angle member 'H secured to the door post 21 by riveting or welding. It will be apparent from a cursory comparison of the structures shown in Figs. 2 and 7 of the drawing that the latter secures the same effective baffles as is provided in the former.

A further modification of the invention is illustrated in Fig. 8 of the drawing. This modification utilizes the door post 6| shown in Fig. 6. to the rearwardly extending flange 62 of the door post a modified form of post projection flange 18 is fastened. This angle affords an outwardly extending flange I9 for the securement of the post strip 25. The remaining flange B of the post protection angle extends along the wall Il and is deformed so as to provide a channel shaped portion 8|. .The web 82 of this portion is offset outwardly from the wall and is connected to the flange 8E! by the obtusely disposed flanges 83 and 84. The sheathing 63 of the car wall is disposed between the flanges 62 and 8i! and is fastened by the rivets which secure these flanges together.

These rivets are utilized, moreover, to fasten an angle member B to the post protection angle. One of the flanges 86 of this member extends outwardly from the wall so as to serve as a baille.

It will be apparent from the foregoing description of the modifications illustrated in Figs. 7 and 8 of the drawing that the objects of the instant invention are secured by these modifications.

It will be apparent that numerous changes and modifications in the details of the invention will be clear to those skilled in the art. It is intended, therefore, that all such modifications and changes be comprehended within this invention which is to be limited only by the scope of the claims appended hereto.
