MADLAND WEATHERTIGHT SLIDING CAR DOOR Filed Sept. 3, 1947 I m I I J I llllllllll!'lflz Patented Jan. 1, 1952 WEATHERTIGHT SLIDING CAR DOOR Gabriel Madland, Chicago, 111., assignor to The Youngstown Steel Door Company, Cleveland, Ohio, a corporation of Ohio Application September 3, 1947, Serial No. 771,979

This invention relates to car door construction and is directed more particularly to structures serving to obtain weathertightness at the front edge of sliding doors of railway cars.

It is an object of this invention to provide structures for the front edge of sliding doors of railway cars which shall improve the weathertightne'ss of this edge in a simple and economical manner.

A further object is to provide weathertight structures for the front edge of sliding doors of railway cars which shall utilize a member on the front door post of the cars as a weather-excluding and door abutment member and an additional weatherprooiing member spaced from the door and post member and cooperating with the latter to form a pocket adapted to trap and discharge foreign matter outwardly of the car.

A further object is to provide weathertight structures for the front edge of sliding doors of railway cars which shall embody members on the car wall so constructed and arranged as to form a pocket that is closed off from the interior of the car.

A further object is to provide 'weathertight structures for the front edge of sliding doors of railway cars which shall include a pocket for trapping foreign matter and a flange serving as a doorabutment and as means for preventing communication between said pocket and the interior of the cars. V

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

In the drawings forming partof this specification:

Fig. 1 is a fragmentary elevation of a wall of a railway car showing the adjacent portion of a sliding door and embodying the instant inventlon.

Fig. 2 is a horizontal section takenon line 2-2 of Fi Fig. 3 'is a horizontal section similar to Fig. 2 showing adiffe'rentembodiment of the invention.

Fig. 'is a horizontal section similar to Fig. 2 showing another f orm'of the invention.-

Referring first to the embodiment of the in vention illustrated in Figs. 1 and 2 of the drawings, the numemi l'fl 'designates a portion of one .of the sidewalls of a railway car adjacent to the front edge of a door opening ll formed in said wall. The indicated 'portionof the car wall embodies a front door post [2 to which nailin'g blocks l3, l4 and I B'ma'y be 'securedin any desired manner. Inner lining l8 constitutes a'part'of the .wall of the car and is'fa'stened as by means of nails to 6 Claims. (Cl. 20-21) V 2 the nailing block i5. The car wall also includes metallic sheathing i'l WhiCh'lS secured to the web 18 of the door post as by means of rivets l9. With particular reference to Fig. 2 it will be observed that the door post I2 is substantially Z-shaped in section and arranged with its web l6 parallel to the wall. In addition to the web the door post embodies an inwardly extending flange 20 and an outwardly extending flange.2l which defines the front edge of the door opening ll. Flange 2! is flanged forwardly as indicated at 22 and'then outwardly as shown at 23 to forman abutment flange for limiting closing movement of a sliding door 24 mounted on the car wall in any desired manner. For the purpose of the instant invention the door 24 which is of wellknown construction may be described as embodying a metallic panel 25 formed with spacedhorizontal corrugations 26 which merge into an outwardly and forwardly offset portion '21 of the panel. This portion of the panel is bent forward 1y to provide a flange 28 parallel to the door.

The front portion of the panel is reinforced by means of a vertical substantially Z-shaped member 29 having a flange 3i] overlapping and secured to panel flange 28 as by means of rivets 3|, an inwardly extending web 32 and a forwardly extending flange 33 which is bent outwardly to form a flange 34 adapted to abut flange '23 of the door post I2. front portion of the door is provided by means of a backing plate 35 secured to the panel rearwardly of panel flange 2? as by means of rivets 36 and 'to flange 33 of the reinforcing member as by means of rivets 37.

As illustrated in Fig. 2 of the drawings, it is preferred that when the door is in its fullyclosed position flange 3% of the vertical door reinforcing member 29 project outwardly beyond the door post flange 23.

A substantially Z-shaped weatherproofing member 38 is secured to the car'wall H] by means of the rivets H? which serve to fasten the metallic sheathing I? to the door post. 'Weatherproofing member 38 embodies a flange 39 through which the rivets l9 extend, anoutwardlyextendingweb 40 and a rearwardly and' outwardly inclined flange 41' which overlaps the forward marginof the door whenthelatter is closed. It will beobserved from Fig. 2 of the drawingsthat weatherproofing member .38 is so related to the door post and the front edge of the door that its web 48 is spaced "substantially from door post flange '23 and its outwardly and rearwardly inclined flange 4| is spaced from flange 34 of the vertical door Additional reinforcement for the Q reinforcing member 29. By this relationship it will be apparent that a free unimpeded passageway is provided for air, dust, cinders, rain, snow and the like into a pocket 42 formed by the door post and the weatherproofing member. Such matter will be trapped in the pocket outwardly of the door opening. Y I

It will be observed, moreover, that the outwardly extending flange 23 on the door post extends across the joint 43 between the inner face of the door and the forwardly extending door post flange 22, thereby forminga barrier to the entry of the noted matter into the car through the door opening.

Another form of the invention is illustrated in Fig. 3 of the drawings. In this form the door post 44 is substantially channel-shaped in section and embodies an outer flange 45, an inwardly extending web 46 and an inner flange 41. Secured to the flange 45 by means of the rivets [9 which serve to fastenthemetallic sheathing llrto said flange is a substantially channel shaped memher," which has spacedforwardly extending flanges 49 and 50 connected by means of an out wardly extending web at the forward edge of the door opening. The rivets I9 pass through the flange 49. Flange 50 is bent outwardly to form a flange 51a which serves as an abutment to limit the closing movement of. the door. 7 V

A substantially J l -shaped weatherprooflng memberliz similar to member 38 is secured to the car wall by ineans of rivets Iii which extend through a flange 53 of said member. Member 52 also embodies an outwardly extending web 54 spaced substantially forwardly of flange 5i and arearwardly and outwardly inclined flange 5 5 spa ced from the door '24. e A

, A third embodiment of the instant invention is illustrated infig. 4 of the drawings. In this embodiment the door post is formed of an angle member SQhaving a flange 51 which is parallel to the carwall and to which the metallic sheathing l'l issecured as by means of the rivets l9 and an inwardly extending flange 58. To the latter flan e a substantially channel-shaped member 591s secured as by means of rivets 60 which pass through the web 6| of the member. Extending forwardly of the web 6| are inner and

outer flanges

62 and 6;, the latter being bent outwardly to form a door abutment flange 64. The considered, embodiment of th'e invention utilizes the weatherproofing member 38 whose :web .40 is spaced from door post flange 64 and whose flan e 4| is spaced outwardly of the said portion of the It willbe apparent from the foregoing description of theembodiments illustrated in Figs. 3 and 4, of the drawings that pockets '65 and '66 are provided to which free access is had by foreign elemerits through the passage provided by the relationship between the door post mmebers, the

front margin of the door, and the weatherproof member. theseemb'odim'ents as wellas in the first described embodiment, the outturned flanges Sid and 64-, respectively, serve to bridge 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. v v
