' To all whoa-zit may concern:

Be it known that I, RAYMOND C. DUDLEY, a citizen of-the 'United States, residing in Chicago, in thecounty of Cook .and State V oflllinois, haveinvented a new and useful 1 Improvement in- Car-Roofs, of which'the following is a specification.

My invention relates to sheet-metal roofs for freight-cars; and it has for an object the. providing of an especially simple; eflicientand readily applied all-steelroof, with the several features 'of improved" construction' hereinafter described or claimed' -of the-figures, Figure 1 is atop planyiew of .In the accompanying drawings, forming a part of this speclficatlon, and n which-dike.

to allow the sheet some lateral plai between the opposed carlines that. support it. Th

ends of the sheets rest upon :the side plates 'of theroof and have downwardly bent iiai'iges 28, 98 that aresecured to the fast-a 29 by the clips 80, 30, each clip being fastened by a bolt 31 and spike 32, the latter A sheet-metal cap member 33 covers and rests upon the entire length of the top flanging of each carline, conforming to the curvature thereof. Said caps have downwardly extending lateral flanges 341 3 with out wardly turned lower edges35,3.3 that rest upon the sheets .26, somewhatwithin their flanges 27, and serve to hold'said sheets in placeand exclude water from entering between thesheet-edges and the webs of the carlines.- The said flanges 3%,] 31 of .each

cap are bentslightly inward toward each mathrough the aforesaid flange 2901' the l tel;-

other, so that the cap may more firmly grip I the carline and exert some spring pressure upon the. sheets E26 that said jfianges 34 e ngage. At either endjof each cap. thesaid lateral flanges-34 are cut free of the'to'p of the cap, and the said free tips, 36,36 are bent inward and folded over each other, so

as to cover the endof' the web and top llanging of the inclosed cal-line. and thee'n'd 87 ofthe top of the cap is bent down over said iu wardly' folded fiange-tips 3G and brought down over and spiked to the fascia of the roof, thus securing the cap at. each. end" and makinga water-tight closure oyer the end of the inclosed val-line. The wooden saddle 38 surmounts the apex ofea' ch capped cur line, and the thus superposedsaddle-and *ap and carline are. secured to the ridge beam ofthe roof by the throughcenterbolt 39, passing through the saddle and the cap and the top and bottom 'l'langcson' one side of the web of the carline. The flanged edge of eachsheet 26 has a recess -10 formed in it, to clear the center-bolt 39 without requiring the sheet to be perforated by u bohhole that would offer an omiorlunily. tor

leakage. To permit the sheet-edges to he as 100 65 carlines to the ridge;

closely as possible upon the bottom flanges of the carlines, slight bosses 41, 41 may also be struck up in the edge of the sheet to freely accommodate the rounded heads of the purlin bolts 25. course spiked upon the top of the saddles.

In making repairs, the depending flanges at one end of asheet'may be bent up and the mits the sheets great freedom in shifting and 'yieldin as the car weaves under'the strains it is subjected to in service, and also facilitates the above mentioned sliding insertion or withdrawal of the sheets in either applying or making repairs on the roof. The I- beam form of the carline greatly stiflens it and aifords a firm support for the cap that straddles it; and also permits the effective application of the single through bolt that binds the saddleand cap and carline-upon the'ridge-beam, I

My invention'is hereinabove set forth as embodied in a particular form of construc- 5 tion, but I do not limit it to such particular form or to less than all the possible con structions in which the subject-matter of the'herein-following claims may be embodied and distinguished from prior devices for 40 like purposes.-

mounting said caps and carlines; and secur means binding said saddles andcaps and substantially, as specifled. 1 4 2.

6. Ina metallic car-roof, in combination:

theirwebs vertical; laterally and upwardly flanged metallic sheets resting upon the bota series of I-beam steel carlines', having tom flanges of the adj acent'opposed carlines i i and secured to the sides of the car; laterally and downwardlyflang'ed metallic caps straddling and resting upon the carlines and covering and'inclosing the aforesaid flanged edges of the sheets, the lateral flanges of said caps being sprung inward toward the Web of the carhne; saddles surmounting' said v caps and carlines; and securing'mea-ns binding said saddles and caps and carlines to the ridge; substantially as specified.

In testimony whereof I have hereunto set my hand m the presence of two subscmbmg Q 10 fvitnesses. I v
