17 Claims.

As is well known in the art, thebleak exposure 7 of the car exterior to winds from all directions and to air streams raised by the movement of the train and by the passage of trains on adjacent tracks sets up strong direct currents and eddy currents tending to enter the crevices between the car door and body and many sealing structures have been designed to prevent the passage of such air streams. the problem is increased when the involved parts are constructed of structural steel members, pressed panel forming plates and other steel parts, the surfaces of which are not true as they would be if machined and fitted individually. Even if the doors and wall members are accurately fitted when first assembled, subsequent.

deformations due to the weaving of the car, track irregularities and rough handling by train men, shippers, etc. would negative the permanence of the weather seal. g

The main object of the present invention is to provide a more effective seal around the door than has been obtained heretofore and more particularly to provide such a seal by simple inexpensive and durable parts whereby the useful life of the seal will be prolonged. This and other 5 detailed objects of the invention as appear in the following description are obtained by the structure illustrated in the accompanying drawings in which:

Figure 11s a side elevation of a portion of a 0 house car body and a sliding door mounted thereon. I

Figure 2 is a horizontal section taken on line 2-2 of Figure 1 and drawn to an enlarged scale.

Figure 3 is a vertical section taken on line 3-3 The diflicuity of The car body includes a side sill l, a floor edging 2, flooring 3, a W-shaped side plate 4, body door posts 5 and 6, outer wall plates 1 and inner sheathing 8. At the door opening the bodyincludes a threshold plate 9, a door header l0,a' front door stop II and weather seal elements i2, i3 and I4 referred to in detail below. Brackets l5 and |5a on side wall I, carry a door track I6 on which the bottom edging of .a lift type door rests when the door is stationary. When the door is to be moved, it is raised and its weight transferred to rollers I! as described in my copending application, Serial No. 231,141 filed September 22,- 1938.- However, the manner of mounting the door isimmaterial to the present invention.

The door is shown as comprising a, front edging l8, a rear edging IS, a bottom edging 20 and a' top edging 2], all of relatively heavy rolled or pressed shapes, and a plurality of. relatively light 5 panels 22, the lower portion of each, (except the bottom panel) includes a U-shaped part 23 extending over the upper edge of the next lower panel and overlying the same to provide a box section reinforcement extending from edge to edge of the door. The lower edge portion 24 of the lower panel overlaps the bottom edging 20. Top edging 2| extends from the inside of the downwardly opening pocket 25, formed by side plate 4, downwardly and outwardly over the upper edge of the top panel 22. Hence there are no upwardly facing crevices from the car roof to the side plate in which water may gather to seep in between the joints and corrode the metal parts. I

The door bottom edginglli has a Z contour and the lower flange 26 thereof is inclined downwardly and inwardly so as to oppose and contact side sill I. Restricted portions 21 of flange 26 are crimped outwardly to opposethe inner edge against rattling and also to provide an air baffle. between these parts. Upwardly of the joints between flange 26 and sill I is the downwardly facing pocket 29- formed by floor edging 2 and the downwardly flanged threshold plate 9. Any

air, moisture or dirt tending to pass upwardly through the crevices between the sill and. flange 26 is trapped in pocket 29and there is little likelihood of the same passing upwardly from threshold plate 9 to the interior of the car. The door closing feature and air baflie feature ofelements ,21 and 28 do not depend upon the door being of g the lift type but will be present in the usual flange 3| of the door front edging l8 and thereby cooperate with elements 21 and 28 to move the door inwardly towards the car body. Flange 30 and the adjacent portions of Z door-edging |8 form an outwardly opening pocket 32 for bafliing air streams tending to enter the crevices between the door front edging and stop The web of stop II and the J-shaped element |2 cooperate to form a secondary pocket 33 which traps any air, dirt and moisture passing inwardly from pocket 32 and same may be dropped to the bottom of the door and be discharged over track l6. When the door is closed elements 32 and H are wedged against'each other by suitable locking mechanism K (detailed and described in an application filed by E. A.-LeBeau on August 5, 1938, Serial No. 223,165.) The forward joint is more likely to be. closed tightly and to remain closed than the other joints around the door and comparatively little difficulty is encountered in maintaining the forward seal. The structure forming the seal at the front edge of the door is not new and in itself does not constitute the present invention.

The door rear edging l9 preferably is of Z section and its flange 34 extends in the general plane of the door rearwardly of panels 22 and terminates in a return bend 35 at the inner side of the door and facing the door body with its edge portion opposing and adapted to contact the outer portion of a pocket forming member 36 mounted on the car wall and forming a. pocket '31 facing away from the door opening.

' conversely, diverge in the direction of the door opening. Hence any air stream passing between - elements 35 and 36 will have its velocity decelerated by pocket 38 andthe diverging elements, and moisture, dirt etc. carried thereby will more likely be trapped by member l3 and dropped-to the bottom of the door for discharge over track Obviously, tight joints are not likely to be.

maintained at the forward and rear ends of the door simultaneously. If the door front edging strikes stop before members 35 and 36 have contacted then the opposing elements of the latter and elements 38 and I3 form a tortuous path well adapted to bame-the passage of air and foreign 'matter into the car. If members 36 and 35 The door header l cooperates with the downwardly and outwardly inclined shoulder 4| and depending flange 42 of side plate 4 to form a nearly closed pocket 25. The Z shaped upper edging 2| on the door includes a projection 43 extending upwardly and inwardly through the opening in pocket 25 and terminates in a return bend 44 located above the flange 45 of header II] and inwardly of door "panel 22. Any air current tending to pass under side plate elements 4|, 42 and over the top of the door is trapped more effectively in pocket 25 due to the curvature 44 and foreign matter carried by the air current will drop by gravity and may drain back from the exterior of top edging 2| instead of being carried into the car.

To prevent an air streain in the direction of arrows A (Figures 4 and from passing around the opening above the tops of members 35 and 36 it will be desirable to straighten out the upper portion of element 44 as indicated at 46 and the rear end of this portion 46 will cooperate with member M to baflle such an air stream.

Fig. 6 illustrates another form of the weather seal at the rear end of the door in which the door body outer pocket forming member 58 has its outer element 5| paralleling the side wall and door panel to provide a line contact with the inclined element 52 of a door rear edging'53. ,The offset projection 54 on the door panel 55 is arranged to contact with the outer face of element 5| so that as the door is moved into closed position element 5| will be seized between elements 52 and 54, the latter of which may yield if necessary, to insure metal to metal contact at this point. The door body inner pocket forming member 56 consists of a standard angle and does not include the outer flange extending away from the door as embodied in member l3 previously described.

Fig. '1 illustrates a form of the weather seal provided .at the rear end of the car in which a single body member 60 has an outwardly and rearwardly inclined flange 6| and an outwardly extending flange 62 perpendicular to the side wall. The door edging 63 includes a return bend flange 64 arranged to oppose and (if there is suflicient forward movement) to contact flange 6|. A channel-like member 65 with inclined diverging flanges 66 and 61 is secured to the inner edge portion of the door and flanges 66 and 61 cooperate with the pocket structures formed by members 63 and 60 to baflie any air streams tending to pass between the door and door post to the interior of the car.

Fig. 8 illustrates another form of the invention in which the forwardly facing pocket 18 is formed by a J-shaped angle 1| applied over the inner flange of the door rear edging Z 12 and the rear portion of the latter is inclined inwardly of the door as at 13 to enter the pocket 18 and to cooperate with the sides of the pocket and with the flange 14 on the door body pocket forming member to baflie any air stream tending to pass between the door and the door post to the interior of the car. A separate angular member 18 placed in the open end of pocket 11 cooperates with the flange 18 of door member 1| to baflie the air stream.

Fig. 9 illustrates a similar arrangement in which the main pocket 88 on the door structure isformed by an extension and return bend 8| on the door rear edging 82. A body member 83, which forms a pocket 84, includes a flange 85 arranged to oppose and contact, if there is suflicient forw Inovement of the door, with flange 8|. Do r panel 86 terminates in an inclined portion 8'! cooperating with elements BI and to form a double baflie inwardly of pocket 84.

In each of the weather seals at the rear end of the door, the dooritself includes element's forming a pocket facing in the direction of the general plane of the door and towards the door opening, and a partition therein forming, in effect, a secondary pocket, irrespective of the relation of the door elements to the battle structure.

on the car body.

All of the above described structures cooperate to prevent admission of the air and solid matter to the interior of the car and thereby protect the contents and avoid deterioration of the car parts. The door is thrust towards the car by the inclined flanges of'members II and 38 and the downwardly and inwardly inclined portions of brackets l5. As to these features, the present application is a continuation in part of my copending application Ser. No. 231,141 filed September 22, 1938, the claims of which are now directed to different car door devices. The structures are simple and may be produced and assembled economically and are not unduly susceptible to'injury from hard usage. The sealing structures may be united with each other and with the door or body parts by riveting or welding. The details may be varied in other ways than particularly pointed out herein and exclusive use of such modifications as come within the scope of the claims is contemplated.
