METAL CAR noon.

Application filed December 15, 1924. Serial N'o. 755,825.

This invention relates to metal door constructi'ons for freight cars. y

In the manufacture of metal doors for freight cars, it is extremely important that the 'doors shall be sufficiently strong to resist not only the outward thrustfrom the `contents of the car, but also the jarringl and f racking strains that such doors are subjected to. It is also necessary that these doors should be maintained as light as possible for ease of operation and economy of cost, and should be so supported that they may be easily operated. It is also desirable that such doors should be so constructed or equipped as to effectively exclude the weather. 1

It is an object of this invention to provide a car doorA construction that fulfills the above noted requirements, that is both strong, durable and light, that is constructed for effectively excluding the weather, that avoids unprotected joints and thatis supportedjor easy operation and that is simple and inexpensive in manufacture.

With these and other objects in view which will become more apparent in the'following description and disclosures; this invention comprises the novel lstructure and combinations hereinafter described and more Vap ended claims. n the accompanying drawings which illustrate a preferred' embodiment of this invention and in which similar reference numerals refer to similar features in the different views: g

Figure 6 is a sectional view upon the line VI-VI of Figure 5.

'the T bars 3 and 4 yof the main door. particularly pointed lout and deined in the *Figure 7 is a f1"agmentary sectional of a modification of the front endv structures of the doors. l

Figure 8 is a view similar to Figure 7 of a further modication of the front end structures of the doors.

Figure 9 is a fragmentary sectional view illustrating a front end construction applicable to a single door, with a slightly modified panel.

Referring now to the drawings, it will be noted that this invention has been illustrated in connection with a freight car for It will be noted that each door consists of Aa frame comprising an upper T bar 3 connected by rear edge T bars 5, the heads of which extend at right angles to the plane ,of the door. The inner iiange of each head is deformed by being inclined forwardly for wedging relation with the inclined face of a weather strip 6 secured tothe flange of a Z bar 23 on the adjacent door Vpost 24.

A T bar 7 connects the forward ends of The head of this T-bar lies in the plane of the door and the flange thereof rprojects outwardly. The forward iange 7? of this head is slightlyinclined and odset in an outward direction as shown'in Figures 2 and 7, `or merely inclined asiindicated at 18 in Figures 8 and 9.

A T- bar 8 connects the forward ends of the T` bars 3 and 4 of the supplemental door 2. The head of this T bar lies in the plane of the door and the flange 8a thereof is directed outwardly and inclined forwardly to provide a groove or the like having an outer bevelledwall. -The liange 7al of the T bar 7 is adapted to enter this groove and wedge against the outer inclined wall thereof to effectively seal the joint between the two doors for excluding the weather.

A corrugated sheet metal panel is riveted or secured to each frame. Eachpanel consists of a plurality, three in the present instance, of longitudinally extending sections having longitudinally -extending and outwardly directed corrugations. The panel they are idented as indicated at'13 to inter-V lock the same,

be 'spot-welded to the corners'of the frame sections 9 of the main door have Aheels or flanges 11 at their ends which are formed by bending the terminal metal at right anf gles. These flanges lit against the outstanding flanges of the front and rear T bars and are riveted thereto thus strengthening the door structure and providing a tight joint to exclude the weather. The corrugations of these Apanel sections extend contiguous to the heels or outstanding flanges of the said bars and substantially merge therein to brace or reinforce the same. It will be noted that these panel sections are also se cured or riveted to the flanges of the T bars that lie in the plane of the door, so each end of each section is secured by two rows of rivetsv at right angles to each other. The sides of these panel sections are secured together in overlapping relation and the upper and lower sections are'also secured to the upper and lower frame members. The marably provided wit a heel 11 similar to the heels at the ends and similarly secured.

The panel sections 10 of the supplemental door may have their outer margins provided with heels 11 similar to the 'sections 9. The inner mar ns thereof are however preferably fiat as s own in Fi ures 1 and 2.

' Instead of riveting or welding the panel sections together, they may be provided with telescopic folds 11 and 12 as shown in Figure 6. In referring to said figures, it will be noted that one panel sectionl has its fold inwardly offset-to' bring `the outer surfacelof .the sections substantially ush. After these folds are brought into telescopic relation If desirable, suitable` gusset plates 14 may to increase the strength and rigidity thereof .as shown in Figure 4.

The supplemental door 2 usually carries a wooden gmb 15"at its forward end which ma be 7 maybe secured to the head of the T bar 8 and the Ajlamb secured in theforward angle o f saidv -har 16.l In the latter construct1on,a plate 17 is preferably applied to the Aside`of the jamb as shown.

of the panel sections are 'however bent outwardly to lie along the outstanding flange ofthe T bar 7 to provide heels 11 and they are riveted Vor secured to both adjacent flanges of such T bar. The forward flange of the front T bary 7 is inclined `forwardly as indicated at 18. The supplemental door 2 lted to the front T bar as shown A v1n gure 2, or an additional T bar 16 (Fig.

has a front angle 19 that slopes forwardly *i and outwardly7 to receive the inclined end 18 in wedging relationther'eunder and to vthe main door 1a shown in Figure 8 excepting that the panel sections have their attaching ends outwardly offset as indicated at 21 Vtd bring the inner surface of the sections flush withthe back of the T bars. The front T bar 7 of this-door has its forward flange outwardly inclined atV 18 which is adapted v to enter a channel formed in an angular gm of the upper anel section 10is prefermember 22 secured to a Z bar 23 that embraces the front door-'post 24. The outer clined flange 18 of the T'bar 7. These doors may. be supported in different ways'. One way consists of suspending the` same by means of roller hangers 25 which travel on -a horizontalA track 26 secured above the doorway. In thepresent instance, a single roller support is used for each door, This supportihg means, however, is not claimed in this; application asv it` is made the subject matter of .a oopending applicatlon:

It will be appreciated that the use of T bars for the door has a number-of advantages.. First, ithas the advantage that a usedz and the front'and rear T bars may be readlly fabricated to provide proper deformed angles for weather proofing purposes. In the second place they impart rigidity to the door and in the third place they provide outstanding flanges against which the heels or end flanges of the panel sections may be secured. It will be noted that the end flanges on the panel sections which are secured to these outstanding flanges n'ot only greatly increase the strength of the door, ut at the same time provides a tight weather sealing joint.

We are aware that many Achanges may be made, and ln'umerous details of construction may be-varied through a Wide range without departing from the principles of this invention, and we therefore do not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art.
