' To all LdOl/l it may concern:

lie it known that we. DAVID W. Hnwnswon'rn and Fnnonmci; M. WHY'rn, citizens he inventionrelates tocar roofs of that type in which load-sustaining metallic roofing plates are flexibly connected to each other with a weatherproof joint pernuttnig of relative adjustment under the weaving action of the. car frame. it is the object ,of" the present invention first, to obtain greater flexibility or freedom of relative adjustment of the plates; second, to more securcly fasten or hold down the plates to the roof'fraine; third, to produce a more thor oughly weather proof construction; and fourth, to improve the construction of varione specific features as hereinafter set forth.

1 in the drawings:

Figure 1 is a cross section through a portion of the car roof on line mae of Fig. 5 showing our improvM construction;

Fig. 2 is a plan view thereof; Fig. 3 is a side elevation; Fig. 4 is an enlarged, section through a portion of the roof adjacent to the caves;

Fig. 5 is a cross section on line aew s Fig. 6 is a section similar to Fig. 4, showing a modified construction; and j i Fig. 7 is a perspective view one portion of one of the roofing sheets and a portion ofthe weather cap for engagement therewith. v

With the type of roof to which the present; invention belongs a series of load sustainin r metallic roofing plates are so supported upon the car frame as to have a limited independent movement in the plane of the roof. It is essential, however, to securely fasten these plates down upon the roof frame, and. also to thoroughly weather proof the joints between plates and at the eaves ofthe ear, thishaving been ac: coniplished heretofore in various ways, all

One

.. portion 1 o a holding down menus for the plates at the eaves. which may be easily applied and which permits of readily detaching the plates when necessary for repairs, and which is scientifically correct.

The present invention accomplishes these objects by dispensing with the usual laterally-extending securing bolts and substituting therefor vertically extending securing devices. lnasmuch, however, as it is essential to provide freedom of movement for the I roofing: plates, these vertical securing bolts are not engaged directly therewith, but are attached to the wonthtar-proofingmeans and through the medium of the latter draw down upon the roofing plates to hold jhe same upon the roof frame.

In addition to the :ulmutugeous feature.

just described our improved construction of roof has a further advantageof providing a thoroughly weather proof joint at llie caves, and yet one which does not interfere with the freedom of movement of the roofing;- plates. A still furthc advantage is the dispensing with the usual fascia which protects the upper edge of the sheathing of the our side. Still further, various details of construction have been improved as hereinafter set forth.

A is the side plate of the car body. B are the cnrlines connectiugsaid side plates and preferably attached thereto by brackets As ireferably constructedthe carlines 13 are 0 inverted U cross section, withoutwurdly-extending; base flanges, and are so cured to the bruckets'C by riveting or'bolting. lhe bruclmt U is preferably secured-to the side plate A by vertical and transverse bolts l) and E, as shown in Fig. 4.

i are roofing plates, preferably formed ofrelatjvcly heavy gage metal and supported upon purlins F which are secured to the carlines B. Each of these roof plates is formed with upstandingmarginal side and ridge flanges M and downturned cave flange intermediate web of which extends over the car b dy upper edge of the siding of the l is the downturned flanges on the stripG which enga 'esthe-gmove in the returnhent the plates F, as shown it G are metallic strips the groove 4. Those strips G perform several func- B, with the provision of sufficient clearance for the lateral movement of said plates. At the carlines the adjacent'roofin plates are weather-proofed by caps N which embrace the upstandin flanges M of said plates and are provi ed with foot flanges M for hearing on said plates. The caps N, in addition to weather-proofin the joint. between the sheets, form the ho ding down means for the roof on the car frame. -To this end they are secured to the carlines, preferably by shoulder bolts P. These'are preferably riveted or'otherwise secured to the caps h and extend downward therefrom through apertures in the carline B, being clamped to the latter by nuts P located in the channelor groove of the carline. The shoulder portion P of these bolts operates as a spacer, so that the cap may be securely out ra clamped in position wit wing downward upon the roofing plates beyond a predetermined point. down "without interfering with their freedom of movement.

- This flange The caps N at the eaves are formed so that the channel section gradually merges into a downturned flange O lyin adjacent to the downturned flange J oft e roofing sheets, and an inturned flange 0- passes beneath the returnbent portions 1 of the roofing plates. Both the Han es 0 and O overlap the edges of the roo ng plates so as to form a weather joint. At the ridge,

the upstanding flanges M of the lates F are overlapped by U-shaped ri ge caps Q, and t e ends of these caps, with the upper ends of the carline caps N, are secured to the ridge purlin by junction ca s R.

'Vith the construction described, in. assembling the roof, the carlines' are first placedin position and are secured by means. of the brackets G. The strips Gare also laid along the edge of the side plate A and are secured thereto by nailing or otherwise fastening the upwardly-exten ing flange G does not extend beyond the top of the side plate A and therefore will not cut into the roofing plates supported on said side plate. A depending flange C on the bracket G overlaps the flange (l and wvith the depending This will hold the-plates together this on agement has the double advantage, first,fo forming an extended metallic hearing for the flange C; and second, the holding down of theflange Gr so that it cannot rise to cut or abrade the roofing sheets.

After the carlines and strips G are in position, the roofin plates may be laid, by first engaging tie returnbent flange flange G of the strii v G and then turning the/plate F downward until it lies upon the purlins. The capsN are then placed in position and are secured from the inside of-the car by enggement of the nuts I" with the bolts The ridge caps Q and junction caps It may then be secured in position, after which the roof is securely held against vertical displacement. I v

In operation great flexibility-is secured by reason ofthe fact that each or the plates Fis entirely free from lateral connection with the roof frame. This freedom of movement is limited b the carlines at. the sides of the plates an lg the depend ing flange J and returnbent ange I. Snfficient clearance is, however, provided to take care of the maximum 'd1stortion',to which the car frame is subjected and con sequently there is nothing totwist or disservice.

The caps N are of a eross sectionwhichv will provide clearance for the inverted U- 'sha ed section of the carline as, far asthis tort the roofing plates whenv the car' is in section is maintained. At the eaves, however the carline proper terminates at the inside of the side plate of the car, while the bracket C is tapered from this point to the outer face of the side plate. This permits of formin the cap with a portion lili which graduay changes from the in.- verted U-section, above. the carline to the flat vertical flange O which overlaps the flanges J of the roofing lates. This results in a taperin portion 8 from the top of the invertedIJ to the point of merger with the side flanges N, and a rounded portion 0 at the corner, and to increase the strength of this corner .a depressed portion 0 is formed centrally therein to produce a bracing eflect.

For securing the brackets C to the side plates the bolts E arepreferably provided wit-h squared heads. To prevent accidental turning ofthese bolts and the loosening of 120,

the same from the clamping nuts, on the inside of the car, these square heads are arranged to bear against the underside of the strip Grand thus when thestrip is in position the bolt is lockedfrom turning.
