STEEL ROOF.

Specification of Letters Patent.

Patented May ll, ldt' Application-tiled January 15, 1916. Serial No. 72,254.

To all whom/'15 may concern.

Be it lniownthat l, lxnn M. Bimini, residing at St. Louis. l\Iissouri,and being citi zen ot' theUnited States, have invented certain new and useful Improvements in Steel Roofs, of which the Jfollowingr is a full, clear, and exact description, such as will enable others skilled in the art to which it alipertains to make and to use the saine, reference being had to the accompanying drawings. which illustrate the preferred forni of the invention, though it is to be nnderstood that'the invention is not limited t0 the exact details ot' construction shown and described, as itis obvious that various modi! fications thereof will occur to persons skilled in the art.

ln said drawings- Figure l is a plan view ot' a portion of the rootl showing the central and side panels thereof assembled.

Fig. 2 is a longitiulinal sect-ion through a little more than one ot' the assembled root units and is taken on line 2-2 ot' Fig. l.

Fig, il is a ltransverse section` through slightly more than one halt ot the roof, the section being in the plane indicated by line 3--3 oi" Fig. l..

Fig. l is an enlarged fragmentary plan view otl a portion of one oi the roof joints i and shows the method of joining the roof pans together for the root.

Fig. 5 is a section taken on line oit Fig. L

Fig.- (3 is an enlarged detailed section through one ot' the rootl joints being taken on line 2 2 of Fig. ll.

. Fig. 7 is a `fragmentary side elevational view of the root and illustrates the casting anchoring the rootl sheets to one of the side plates of the car.

Fig.I H is a detailed section showing the cap piece. mounted upon root pans.

Fig. il is another detailed section taken through a portion ot one ot' the side plates au,d the end ot' the roof pan that rests thereu ion.

Fig. Vl() is a. perspective vlew otl a portion of one ot' the cap pieces, and

Fig. ll is another perspective view of to t'orin a supporting arch the root pans but with the cap piece re- 'moved This invention al'ipertains to modern steel roofs and has for an object the portions of such a roof wherein extended ventilation spaces are present throughout the length of the car and between the positions of support of the roof.

In addition to the ventilation, flexibility is given to the roof and the latter coniprises sections so joined togetherl that the roof is thoroughly water-tight.

Another object is to so form the elements of the sections or units and associate with thein auxiliary parts insuch manner that a self-supporting roof structure results.

Other features of the invention will become manifest hereinafter and come within the scope of the present invention.

Referring to the drawings, l indicates a series of central panel sections having an end to end disposition and extending longitudinally ot' the car. The central panel sections are of channel-shaped cross section and have depending flanges 2 along the-ir sides. At their meeting ends the central panel sections are each provided with npstanding flanges 3, those of one section hav ing vertical contact with the adjacent flanges 3 of the next sections except in the ,end portions 3 of said flanges 3, said end portions 3 being bent with an appreciable curvature so that those of contacting flanges 3 are turned in opposite directions.

0n each side of the central panel coinprising the central panel sections l are side panels comprising a series of successive roof pansl of substantially the saine length as the sections l of the center panel. In reality the root'pans 4, which are of sheet metal, are of slightly less length than the central panel sections l so that the vertical flange of a n angle. 5 may extend between the juxtaposed upturned flanges 7 of Vadjoining root' pans. As seen in Fig. 3 `angle il is somewhat longer than the width of the Center sections l but such excess of length is, preferably, only extensive enough to provide suiiicient riveting area for the transverse lianges 7 of the. roof pans l, rivets S connecting said flanges with the upstanding flange of angle 5. The upperedge of the vertical flange ot' angle 5 in passing under the central panel sections l lies entirely under the meeting line o'f' the abutting upright flanges 3 of adjoining central panel seetions as is shown in Fig.. 6. Roof .pans filare each provided with an inner npstandin'gl flange 7a whichf is really a continuation v end f `Fig. 1. Extending outwardly from each `end oftie ruiming board supporting poi'` opposing teiniiiials r2 of the side. flanges 2 ofthe center panel of the transverse roof'pan flange 7, both flanges 7 and 7 being merged by rounded corners. The inner flanges 7a of roof pans t lie against the inner faces of the depend'- ing side flanges 2of the center enel sections l and are secured thereto t roughout the major portions thereof by rivets 9. rI he portions 2 of. each depending side Harige 2 of' each center panel section 1 are deflected outwardly so that the opposite ends of each center panel section are flared as best seen in Figs. 4: and 11. The flared portions 2l of the side flanges 2 of the center panel sections terminate at the outer faces 'of the sides or depending flanges 10 of the joint cap 11. The outer edges of the ei'teir `sions 3 of the upstanding center panel section flanges 3 bear against the inner f ace's of the depending side flanges 10 of the joint cap 11 and between the terminals of the upstanding flange end portions 3 and the of the flared portions A notch 12 side of the section are formed notches 12. is, therefore, present at each joint and the depending flanges 10 of the joint cap have their inner edges inserted into the notches 12` the joint cap thus becoming interlocked with the sections of' the central panel at each joint.

As clearly sccn in Fig. 4, the flanges 7 and4 7 of the roof pans -f lie well within the depcndin flanges 10 of the jointwcap 11 and the de ected flange portions 2 of' the central panel sections. The curvature of the extensions 3 of the upstanding flanges 3 of' abutting center panel sections is such that water draining from said center panel sections will be deflected b v thc extensions 3 of the flanges 3 into thc roof' pans 4, preserving the unter-tight qualities of the joints between the units comprising the center panel sections 1 and the side panel sec-v tions coinprehendin f the roof pans. The joint. caps 11 each has a centralportion 3 adapted to support running boards 14 which are. secured to said center portidns 13 of the joint caps by bolts or other suitable means.

Running boards 14 are also afl'orded sup port. by ribs 27 pressed upwardly-1n the central panel sections] as clearly shown in tion 13 ai'e inverted U-shaped portions of .said'joint cap which contain the d pending side flanges 10. These inverted shaped port-ions extend to the carside ,and gradually increase in width as they do so.

In the upper U-shaped portion of the joint ca) is generated a continuously widening c iannel or groove 15 which is widest at the car sides.-

As said channel progresses outwardly, it also increases in depth and at its outer end the depending flanges 10 of the joint cap rest upon the roof castings 1h surface of' each inverted Leganes 11 are secured to flanges 17 ofan anchor castingI 18 by rivets 1t).

Castings 18 serve to anchor thc root structure to the side plates 1G of thercai, each having a bottoni flange 2S riveted to the bottoni outstanding flange of the Z- shaped side plate 16. Between the flanges 17 the anchor casting web 20 is provided along its upper edge with a rib 20 adapted to support the roofl pausa through the contact of the bottom edges of' their eaves flanges 23 resting upon'said rib 20 of' the lower web 20 of anchor listing 18. Also between the vertical flanges 17 is an" upper web 21 and 'ioin thercar of the latter inwardly extending fingers 22 engage and pan sheets adjacent the eaves .flanges 23 which depend from the outer edge of' cach root' pan 4. Said anchor are cach also` provided with a top flange, 2l which is conformed to the shape of thc channel or depression 15 in the upper side of the joint cap 1i.

The webs 20 18 lie in, different vertical planes, the lower web 20 lying against the outer face of' the web of side plate'I 16 and the upper web 21 being spaced outwardly therefrom. Said anchor casting' webs 2() and 21 are also vcrtically spaced from each other to produce t e aperture 25 vbetween theinf The rootI panretaining fingers 22 being more narrow than the width of the lower and upper anchor casliiig-webs20 and 2l, and the caves flanges 23 of ad pans being spaced apart an air passage is created, the inlet of which is the space 25 between the upper and lower webs 2l and 2 0, respectively, that is present between the fingers 22 and the edges of adjoining eaves flanges 23. As seen in Figs. l and 3 this passage is maintained above the upper flange of the side plate 16 by depressions 26 progressively spaced in thebody portions of the rootI pans 4. The material in the bot# tom of sai(l clepi'essioiis 26 lies upon thel top flange of' the side plate 1G causing the bQdv portions of the roof pans l to be spaced li suitable distance above saidv side plate top flanges, thereby.maintaining the air passage 'from the aperture 25 in the anchor casting 18 to the interior of the car at the joints. i

It is also obvious that inasmuch as the eaves flange 23 of each roof pan is spaced from the outerlfaces of the webs of' the side lplates 1G throughout the lengths of said side plates a series of successive air passages is created along the car sides throughout the lengths thereof. i

Between successive depressions 26 the air passage extends from the bottoni of eaves flange 23 and exists between the inner face of said flange 23 and'the outer face-of the web of the side plate to the top of the latterA and 2l of' thc anchor casting respectively, joining roofilOC Massese passage continues between the upper tace of the top flange of the side plate 16 and the under face of the body portion of the root1 pan to the car interior. Similar air passages, of course, are present between each anchor casting '18 and the next adjacent de pression 26 on either side thereof.

From the foregoing it is evident that the improved roof is provided with Va central panel and similar side panels on opposite sides thereof 'and that each of these panels are made up of sections. Each central panel section and the side l)enel sections, heretofore called roof ans, which are alined therewith transverse y of the car, constitute a root' unit, and these units are arranged successively longitudinally ot the car, and, as

joint caps interlocking with and connecting 1 acl set forth, are secured to ether resulting in a strongly connected roo structure.- 1t has also been Iliade plain that adjoiningrool' units have their joints thoioughly Weatherprooed, and that the joint caps are constructed to shedaccumulated Water and have portions which coperate with ribs in the central panel. sections to supportl the usual running boards. 'L

Another novel feature developed, is the combining of the. transversely arranged .dam-Yes 7 of the roof pans with the relatively short, centrally locatcdtransverse angle 5 so that the resultant structure is'the equivalent of afcarline cxtendingrom one side plate 16 to the side plate 1G at the opposite side of the carl The joining together ot the opposite flanges 2 and 7 of the central panel sections and y.the roof pans, respectively, creates a roof which extends from car side to car side, andas there are spaces between the inner faces of the eaves flanges 23 of the roof pans Qi and the outer faces of the Webs of the side plates 1li, the roof is possessed of flexibilitytransversely of the car.
