extending across the top of said side'plate and along the longitudinal edge of the flange l j and terminating at the junction of'the top 'which extend iongaudinauy of the trough,

v and outer side of said side plate. Each depressed part b of each flange b is riveted, as at 8, to the top flange a; of the adjacent side plate and spaced.l from k,the adjacent side of the trough so as to effect the formation, between said side of the trough and said depressed part of said flange, of an air- .conducting -passageway C arranged externally of the trough wholly between said side lof the trough and the longitudinall edge of said flange and kwholly above said side plate, and preferably said passageway is parallel with the trough and straight from end to end "and extends longitudinally of the trough and'across the top of the adjacent side plate. It will be observed therefore that the carline illustrated has such contour along each end-portion thereof as to form two parallel air-conducting passageways and are arranged at opposite sides respectivelyof said end-portion and externally of thetrough, that opposite side walls of said p'assageways are formed by said end-porauf f plate. and consequently with the room internally of said car. y l

Across the top of the trough B, at points "'between .theside plates A, extend the ridgel Ition of the carline, and that said passageways are in open relation at their outer ends with the atmosphere at the outer slde of sald side' plate and consequently in communication with the atmosphere externally of a car provided with a roof embodyingA my invention and `communicate at their inner ends with the space, at the inner side of said side poleV D and purlins Il, and said members D and E rest on theflanges bf and are secured to said flanges in any approved manner, -and i on said members D and E rest the roofingf boards G having an outer metal covering g.

The carline-trough By extends into the lower portions l of wooden bars I-I which rest on and extend longitudinally of andare se- ,cured to the top flanges a of the side plates A, and said bars are recessed, as at 10,lto accommodate the location of said trough which terminates therefore within the recesses 10 in said bars, and the roofing-boards also rest on and are secured to said bars. The bars H extend widthwise outwardly beyond the ends of the cai-line and beyond the outer sides ofthe side plates A and are provided at their outer side with fascia h shown covered at its outer side by the metal covering g of the roof. The fascia 7b of each bar H extends along the outer side of the l adjacent side plate A' and is spaced, as at K,

fromsaid side plate and from the trough B, and the space K thus formed between the inner side of said fascia and the outer side of the said side plate and between said fascia and the trough is open at the bottom and communicates at, the top with the adj acent air-conducting passageways C.

Obviously a car having a roof embodying my invention is adequately ventilated through the medium of my improved carline hereinbefore described. Sweating of said carline where the carline is exposed to the air within the car is preventedn Said carline is preferably made from an oblong rolledsteel plate pressed into the shape rev quired to form the carline and has its end` port10ns meritoriously serving` as ventilators next externally of the trough of the carline,

v and I would here remark that the uniformity in the internal width of the trough of a carline thus made results in the formation of langesb which are wide enough along the end-portions ofthe trough to permit of the formation ofpassageways C which, as shown, are as wide at their outer ends as at any point between/their ends and have an adequate air-conducting capacity.

What I claim is 1. In a car-roof-frame, the two laterally spaced side plates, and a metal carline comprising a vtrough which bridgesthe space between and extends over the side plates and is provided at the top and externally with two laterally and outwardly projecting flanges arranged at opposite sides respectively and extending from end to end of the trough, there being formed, over each side plate, two passageways extending longitudinally of the trough at opposite sides respectively of the adjacent end-portion and externally of the trough, which passageways v are in open relation at their outer ends with the atmosphere at the outer side of the. ad-

/jacent side plate andcommunicate at their inner ends with the space at the inner side of said side plate, each passageway being adapted to conduct air from one to the other side of the adjacent side plate and arranged wholly between the adjacent side of the trough'and the longitudinal edge'of the adfjacent flange of the trough.

opposite sides respectively of the adjacent end-portion and externally of the trough, which passageways are in open relation at their outer ends with the atmosphere at thc outer side of the adjacent side plate and communicate at their inner ends with the space at the inner side of said side plate,

menare each passageway being arranged wholly betweenthe adjacent side of the trough and the longitudinal edge of the adjacent flange of the trough and wholly above the'adjacent side plate.

3. ln a car-roof-frarne, the two laterally spaced side plates, and a carline comprising a trough which bridges the `space between and extends over the side plates, said carline having such contour along each endportion thereof as vto form two air-conduct'- ing pa-ssageways which extend longitudinally and are arranged at opposite sides re `spectively of said end-portion and extertrough and over the side' plates, each end-l portion of each flange having a depressed part which is arranged over the adjacent side plate and extends longitudinally of said dange and transversely of said side plate, there being an air-conducting passageway formed between said depressed part of said flange and the adjacent side of the trough, which passageway extends longitudinally of the trough and is lin open relation at its outer end with the atmosphere at the outer side of said side plate and communicates at its inner end with' the space at the inner side of said plate. l

5. ln a car-roo frame,.the-two laterally spaced side plates, and a metal ca rline comprising a trough which bridges the space between and extendsi across the tops of the side platesand is uniform in width internally from end to end and provided at the top and externally with two laterally and' outwardly projecting flanges which extend rom'end to end ofthe trough and are wider along their end-portions than along their central portion, each end-portion of each flange having a depressed part which is arranged over the adjacent side plate and extends longitudinally of said flange and rests on said side plate, formed between said depressed partI of said flange and the adjacent side of the trough, which passageway is lparallel with the trough and adapted to conduct air across the top of said side plate from one to the other side of said side plate, `said passageway being as wide at its outer end as at any point between its ends.
