THOMAS NATHAN RUSSELL, OF CHICAGO, ILLINOIS, ASSIGNOR TO CHICAGO-CLEVELAND CAR ROOFING COMPANY, A CORPORATION OF ILLINOIS.

CAR-ROOF.

1,265,523. Specification of Letters Patent. Patented May 1918, Application filed September 1, 1914. Serial No. 859,675.

To all whom it may concern:

Be it known that I, THOMAS NATHAN RUS- SELL, a, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented. a new and useful Improvement in Car-Roofs, of which the following is a specification.

The invention relates to outside metal roofs for freight cars, and has in view several features of improvement which are partly improvements in the roof patented to me December 2, 1913, No. 1,080,173. The present improvements are concerned with the formation of the seam by which the edges of the roof sheet, along the lines from the ridge to the eaves are united with each other, in such manner as to make such seam a perfect water seal, and also to make it strongly resistant to any superimposed weight, and at the same time to save metal in the roof sheet and in the seam. This result is attained by an improved conformation of the interlocking edges of the roof sheets, so that the above advantageous results are attained without necessitating the use of a separate, external seam cap. With, and as a confining and supporting means for, the said seam I employ an eaves seam clip of improved construction, arranged to confine the seam upon the top, and at the sides, and also supported from below, at the same time providing for the ready escape of cinders, dust and moisture.

With such objects in view the invention consists in the parts and combination thereof hereinafter set forth and claimed.

In order to make the invention more clearly understood there are shown in the accompanying drawings means for carrying the same into practical efi'ect, without limiting the in1pr0vements,-in their useful applications, to the particular construction which, for the purpose of example, has been delineated. In said drawings- Figure l'is a plan view, partly broken away, of a car roof embodying the invention'.

"Fig. 2 is a vertical transverse section of :theroof', on line II-II of Fig. 1, a portion-of the same being broken away.

Fig. 3 is a. similar section of the eaves portion of the roof, on a larger scale, on line IIIIII of Fig. 6.

Fig. 4: is a transverse vertical section showing the ridge seam by which the roof plates are united.

Fig. 5 is a vertical section, on line V-V of Fig. 1, and partly broken away, showing portions of two of the roof sheets united to form a seam.

Fig. 6 is a side view of a portion of the roof, and car, the running board saddles being shown in section.

Fig. 7 is a perspective View of one of the roof sheets.

Fig. 8 is a perspective view, partly broken away, of a flashing which may be employed to underlie the eaves edge of the roof sheet and to extend down over the upper part of the fascia.

Fig. 9 is a perspective view of the same clip.

Referring to the drawings, 1 indicates the ridge pole of the car, 2 the side plates, 3 the carlines, here shown as consisting of angle irons extending from side to side of the car and bent to conform to the slopes of the roof, and sustaining on their horizontal flanges filler bars 4 in the nature of rafters, on which latter is sustained the top sheathing 5. The carlines, ridge pole and running board saddles 6 are united by vertical through bolts 7. The vertical flange of the carline is bent longitudinally of the car as shown at 8, and is secured to the inner face of the side plate by a bolt 9. The horizontal flange of the earline is bent upward along the inner face of the side plate, outward along the top of the same, where it may fit in a suitable recess, and downward against the outer face of the side plate, as shown at 10, where it is secured by a bolt 11.- The side sheathing is shown at 12, attached at its upper part to the outer face of the side plate, and recessed where necessary to receive the said flanges 10 of the carlines. The upper end of the upper partof the side sheathing is overlaid by the side fascia 13, which is secured in place by the bolts and nails of the eaves seam clips. The eaves clips are shown at 14: and

may be of any form suitable for the purpose to confine the bent down eaves edges of the roof sheets.

15 indicates the roof sheets, each of which is formed at its ridge end so as to unite in a ridge seam with a contiguous roof sheet at the otherside of the ridge. A seam suit-, able for this purpose is shown inwFig. 4, where one of the sheets is shown as'tormed with an outer inverted U-flange 16 bent away or outward from the main body of its sheet v and the corresponding sheet, at the other side of the ridge is formed with an inner inverted U-flange l7'bent toward and overhanging the main body of the sheet by a return bend. The parts of this seam can be united by mere superposition, and" do not interlock so as to require to be Sl1Cl or telescoped together by movement longitudinally of the seam. This form of ridge seam can therefore be combined with side seams, extending from the ridge to the eaves, which completely interlock and'require to be telescoped together. There'is a tendency in the ordinary form of ridge seam, in which a ill-bend, which-is bent away or outward from'the top of the sheet,

issuperposed over a similar ill-bend, for the seam to be caused to open moreor less and qgape by reason of the tendency of the sheets to work down the inclined planes away from When the usual form of scamthe ridge. gapes in this manner a dashing rain will work through the seam in places and cause leakage in the car. This difliculty is not experienced with the form of ridgeseam which I employ and have illustrated, the action of which is to catch rain which enters under the'return bend 17 andreturn it'npon the top of the roof sheet instead of eon-' ducting it farther into and between the parts of the seam, and such seam can also be employed, as above explained, in combinaton wit'h said seams which interlock and Ithepartsofwhich must be teleseoped together. This structure also forms a very strong, as well as water excluding, ridgeseam independent of any extended ridge cap. I however employ at the points where 7 four sheets meet, short four armed ridgecaps 18;, which are confined by the running board saddles and have perforationsfor duplicates of the sheets at the other side But my improved-side seam can be used with the-ordi.nary=.;tormofridge seam. Atthe eaves endthe roof sheet is Mformed' with an extendedfiange 19' bent downwardly over the fascia, confined by theeaves-clips .14; Eachof the roof sheets is ffQlmGCl along one of itstransverse edges (which extends transversely 'offthe" car from' the eaves. to the ridge) with a dQubIe-I-flangeLQO; 21,- and along its. other transverse edge with a triple flange 23, 24; The members 20 and 21 of the double flange are or may be parallel with one another and, are united at the top ;by a bend 25, and this flange is turned inwardly toward the bodyof the sheet so that the member2l overhangs the same. The menr bers 22 and 23 of the triple flange, together with a connecting arched portion 26, form a segment of a tube, such segment being considerably more than a l1alf,circle. The third flange member 24L extends upward within. the tube. The said parts are so proportioned that the double flange of one sheet may inter-loclr -witlr-the triple flange of-the next-sheet,- as best-seen =at the middle of Fig.5, so thatthe flange member 24 is included within the flange members 20 and 21, and the latter are included within the said triple flange, the latter taking the place of and forming. in client a seam cap which is capable of being supported from below by a-suitable eaves seam clip-.= Each roof sheet so formed is or'may be the counterpart of ever r other and yet comprisesa strong, leakproof and efficient seam cap The caves. seam clips aresshown. 211x27, each. of the same. being formed at its middle part with a hood. 28 which is nearly tubular, so as to fit around and partly. beneathtne outerendsof the said caps or triplefianges 22-, 23,126 From thishood.areextended inwardlya top :projection 29 which holds the cap down'by an extendedbearing, and two bottom projections 30 which fit atthe sides of and partly under the

flange members

22 and 23; The: cap portions otthe roof sheets are thus closely confined in place and supported fromvbe1ow,while the opposite edge-ofthe roof sheet-formed with the double flange20, 21 is left free and. movable as may be necessary relative to all other parts, under the torsional movements of the roof. From-ether hood 28 the seam elipis curvedzoutwardly and-downwardly to conform. to the flange,=19,= two contiguous ends of whichqflanges,.it;confines (Fig. 6), and its lowerpart-ibranched into arms .31 which are perforated so that they maybe secured by nails .to the fascia and side sheathing. The downwardlyextended part of the seam clip; is perforated to receive a bolt 82 which passes through .to the inner side of theside What I claim is:.

1. In ascar :rool the combination of roof sheets having interior and exterior; interlocking seam flanges formed ion theirside ,edges,-. the; said; flanges being spaced from I each other, to all,ow; play x of the interior flanges relative to the exterior flanges, and

corner, by I gripping the. eaves end lot {the exterior; seainv-flange, the other eaves-corner;- bemg .freetoimove within. its seam, whereby each sheet is held positioned along one eaves-to-ridge seam-line only and is free of th shifting of the substructure of the roof under the body and other side seam flange of such sheet.

2. In a car roof, the combination of roof sheets having interior and exterior interlocking seam flanges formed on their side edges, the said flanges being s aced from each other to allow play of t e interior flanges relative to the exterior flanges, and seam clips fixed on the eaves of the car and holding the exterior flanges in position along the normal seam line, the other or interior flanges of the sheets being left free.

8. In a car roof, the combination of roof sheets united at their sides by loosely interlocking side flanges, and confined at their eaves ends, and united by bent flanges to form a ridge scam, the sheet at one side of the ridge having an outward U-bend away from the body of the sheet and the sheet at the other side of the ridge having a return bend over the body of the sheet and contained within the said outward U-bend.

9. In a freight car roof, the combination of roof sheets united by bent flanges to form a ridge seam, the sheet at one side of the ridge having an outward U-bend and the sheet at the other side of the ridge having a return U-bend contained within the outward U-bend, said U-bends being open and downwardly and outwardly flaring for the direct superposition of one sheet on the other.

10. In a freight car root, the combination of roof sheets united by side seams consisting of interlocking side flanges requiring to be telescoped together, and united at the ridge by U-bends adapted to be superposed one on another, the sheet at one side of the ridg having an outward U-bend and the sheet at the other side 01" the ridge having a return U-bend contained within th outward U-bend.

In testimony whereof I aflix my signature in presence of two witnesses.
