and 3 are of-'substantially similar construction, Aexcept that one is wider than the other.

This invention concerns itself more directl with the door structure whereby commercia `ly rolled and corrugated sheets of standardsize may be used in the construction of doorS of different width. The door 2 shows a cor# rugated panel 5 of one standard size while the door 3 shows a corrugated panel 6 vof another standard size. 1

It will be noted 'that the panels are transversel corrugated from one edge to the otherv edge or stiifening the same. A Z-bar 7 is secured to the lower margin of each panel and'v a Z-bar 8 is secured to the upper margin of each panel. The Z-bars for the doors 3 will of course be shorter than the Z-bars for the The lateral margins olf the panels are enclosed by corrugated sheaths, the free mar` corrugated to fitthe panel. The s eaths are A substantially similar except for the weatherprooing features, and they generally consist of a palr of opposed metalmembers havingv intermediate spaced portions with connected margins. The sheaths on the door 2 'are illustrated in detail in Figures 4 to 7 and now be described.

In referring to said fi that the rear edge sheat A9 consists of' a pair of metal members 9? and 9b. The inner member 9b has a rear deformed margin providingI an inwardly andy forwardly sloping flange 9c adapted for engaging an angle member on the car as is well' known in the art.v The forward#l es, it will be noted portion of the member 9b slopes outwardly as indicated at 9d. The end of the sloping p0rtion extends parallel to thedoor and is secured to the member 9'I preferably by rivets 10 or the like. The member v9a has a rearwardly preferably by rivets 10 or thelike.

The she-anna the from edge of the door' 'and inwardly sloping portion 9., the forward lend of which extendsparallel-` to the plane of Vthe panel for securement to the' member 9b 2 is best'shown in'Figure .5. 5 AItcOnsists ofv a member 9'L as 'previously described'fand 'a :member 11 which is similar to .themember 9b with the exception of the outer end which is deformedv to provide a weather proofing flange 11b which extends outwardly and rearwardly. The edges of the sheath 11 are coniacted together preferably by rivets 10 or the The door panel 5 has its lateral margins confined between the respective members of the sheaths and is secured thereto by the rivets 10.

It will be noted as shown in Figure 4 that the lateral edges of the panel 5 are spaced inwardly from the sloping ends 9e of the sheaths. It,` therefore, would have been possible to bring the sheaths closer together until the side edge ofthe panel abut the sloping ends 9e to form a narrower door. It will also be apparent that since the lateral margins of the panel extend into. the sheaths much further than necessary; The sheaths might have been spaced further apart upon the door to provide a wider door. Obviously thru the instrumentality of the sheaths it is possible to construct doors of various widths by using the. same standard size panel. Sheaths of dierent width may also be used Where there is an appreciable variation in the width of doors. tain size will however small variations.

In order to prevent the weather from entering at the top of the sheaths, the Z-bar 8 is outwardly odset as indicated at l2 (Figures 1 and 3) to overlap the upper margins of the sheaths. To shed the rain and weather at the lower ends of the sheaths, the outer members thereof together with the panel 5 are offset over the Z-bars as indicatedat 13.

With reference to Figure 2 itwill be noted that the upper fiange of the Z-bar 7 at its ends lies betweenthe panel 5 and the inner member of the sheath. f It will also be appreciated that while the sheaths make it possible to construct doors provide` for ordinary 'of different width, they also stiften the door and impart suilcient rigidity thereto to prevent objectionable weaving or flexure.

We are aware that many changes may be made and numerous details of construction may be varied throughA a wide range without departing from the principles of this invention and we therefore, do not propose limiting the patent granted hereon otherwise than as necessitated by the prior art.

. We claim as our invention:

-1. In a railway car door, a metal panel the panel, the outer margin of one sheath -having an inwardly and forwardly bent ange, the outer margin of the other sheath having an outwardly and rearwardly directed iange. ,f

2. In a car door, a metal panel having corrugations extending from one edge to the A pair of sheaths of ceropposite edge and corrugated sheaths enclosrugations extending from one edgeto the' opposite edge, and stiifening Icorrugated sheaths enclosing said edges, each sheath comprisingspaced intermediate portions and anv outer deformed margin for the purpose set forth. 4

5. In a metal car door, a marginal stidening sheath comprising a pair of members having intermediate spaced portions and connectedmargins, one margin being deformed for thepurpose set forth.

comprising a pair of corrugated members having intermediate spaced portions and connected margins, one margin being deformed for the purpose set forth.

7. In a metal car door, a metal panel, a metal sheath consisting of superposed members embracing the lateral margin of each panel, and slidable in relation therewith before securement to secure the proper width of door; each sheath having a deformed outer margin for weather proofing purposes.

In witness whereof, we have hereunto sub scribed our names.
