RAILWAY CAR noon AND POST STRUCTURE Fil ed Sept. 5 1942 2 Shets-Sheet 2' INVENTGR; AXEL WASBERG Patented July 23, 1946 V '1" OFFICE RAILWAY CAR. nooaANn POST STRUCTURE Axel Wasberg, Chicago, Ill.', assignor to Chicago I Railway Equipment Company, Chicago, 111., a corporation of Illinois Application September 5, 1942, Serial No. 457,405

The invention relates to the formation of a weather excluding seal at the forward edge of a sliding door, when the door is closed, such as is adapted to be used effectively on railway box or house type freight cars where the exposure to winds and currents of air set up by the movement of the car tend to drive rain, snow, dust, cinders and other foreign matter to the interior of the car with likely damage to the lading.

In Patent No. 2,226,419; issued to the present applicant December 24, 1940, the front edge of the door and the adjacent postcooperate to form a pair of successive weather pockets opening towards the exterior of the door andserving to ba'flle inwardly moving currents of air and trap dirt, water, etc., carried thereby.

The general object of the present invention is to provide a more effective weather seal at the front edge than that disclosed in' the above-mam tioned patent. One way of obtaining this object is by utilizing a flexible weather-strip element in association with rigid elements on the door and post to cooperate therewith in forming the weather excluding pocket. Another way of obtaining this general object is to have spaced metal elements of the post and door structure provide a third pocket facing outwardly of the car cooperating with successive pockets. as previously disclosed. This general object may be obtained by combining the flexible weather-strip element and the third pocket forming structure.-

(Cl. %26') Other detail objects will be apparent from the following description, reference being had to the accompanying drawings illustrating selective'embodiments 0f the invention in which Figure 1 is a side elevation of a railway box car provided with a side door mounted to slide longitudinally of the car wall to open and close the doorway, V .7

' .The body includes a door front post structure comprising a Z bar withit's, web l-l disposedlongitudin'allyof the car and with one flange l'2 extending inwardly of the car body andthe'other. flange 13 extending outwardly of the car'body and forming one'sidejof the door opening and terminating adjacent to the inner faceof the door Z bar flange l0. An angular member M on the body post has an inner flange [5 rivetedthrough the sheathing and post web ll and has 'afweb l6 extending transversely of the car and forming a stop'against which the door front edge abuts when the door is closed. Post-member Ml-also has an outer'flange 11. extending longitudinally of the car outwardly of the flange lo on'door member! and towards web 8 of the door member.

' Figure 8 illustrates a door seal arrangementresemblin'g'in'somedetailsTthat shown inFigure 2 but modified:iforfapplication to g a main idoonand auxiliary door combination, asset forth incon- '5 nection with Figures 6 and 'I. The door panels 8| and 82, auxiliary door post 83, auxiliary door edging and maindoor stop 84 and angular member 85 are. substantially identical with the corresponding parts shown in Figure '7. The flexible weather-strip member 86 is secured between members 83, 82 and 84 and has a reverse curve projecting portion arranged to be engaged by the oifset' and outwardly bent forward flange 81 of the door front edge member 88. This arrangement provides an outer pocket Q, an inner pocket R and an intermediate pocket S functioning as do the triple pocket arrangement previously described.

Figure 9 corresponds generally to'the arrangement of Figure 4 but shows'the parts embodied in the main door and auxiliary door joint of a double door structure. The post main member 9|, the inner rigid angular member 92, the door front edge member 93 and the door stop member '94 are substantially the same as the corresponding members shown in Figures '7 and 8 except that the inclined forward flange 95 of the door edge member is straight. The intermediate member 96 is rigid and is shaped to provide extended contact with flange 95. Insofar as the member 96 is rigid the structure corresponds to that shown in Figure 4. As in the other forms of the invention, three successive pockets T, U and V are formed to block incoming currents of' air and trap dirt and moisture carried thereby which will be drained downwardly to the bottom of the door and post.

Each form of the invention attains the general object described in the introductory portion of the specification in different specific em bodiments, and it is to be understood that, so far as the present invention is involved, it is immaterial whether the post cooperating with the front edge member of the door is a post forming a fixed part of the car body or is a post mounted on an auxiliary door. The difierent arrangements shown in the drawings are intended to be illustrative and specific features of the body post and associated door may be embodied in the auxiliary door post and associated door and vice versa, as may be deemed expedient. Some of the elements may be omitted, leaving two pockets embodying novel features of the construction. Other variations in details of construction may be made by those skilled in the art without departing from the spirit of the invention, and the exclusive use of such modifications as come within the scope of the claims is contemplated.
