-Fig. 7, looking downwardly. Fig. 11 is a horizontal section on line 11-11, Fig. 7, looking downwardly. Portions are broken away in the drawingsto reduce thesize of the same and to more clearly illustrate certain features of construction, and Figs. from 3 to 11 inclusive are drawn on a larger scale than Figs. 1 and 2. T

The framework of our improved car-roof, as shown in Figs. 1 and 2, comprises two laterally spaced side plates A and A which extend longitudinally or endwise of the carroof and are arranged substantially horizontally and parallel. The said side plates are connected together ,at their ends by beams or rafters B. Under-each side plate A, at each end of the frame of the car-roof, is arranged a post C, and at the outer side of each. side plate .A is arranged upright car-siding D which overlaps and abuts against the outer side of the said side plate and terminates at the top thereof a suitable distance below the top of the side plate.

Metal carlines E are arranged transversely and spaced longitudinally of the car-roof, being arranged between and spaced from the ends of the car-roof. That is, the carlines E are spaced laterally between the end beams or rafters B of-the frame of the car-roof. Each carline E bridges the space between and is supported from the side plates A which are preferably recessed, as at a, in the tops thereof and transversely from side to side thereof to receive the said carline. The carlines E are therefore set into the side plates A at the top of 'the side plates and are thereby pre vented from displacement endwise of the side plates. Each carline E at the outer side of each side plate A has a downwardly projecting end-portion 6 arranged at and overlapping and abutting against the outer side ofthe car siding D adjacent the said side plate. Each car-line E is preferably trough-shaped substantially from the top and outer side of the car-siding at the outer side of each side plate A to the top and outer side of the car-siding at the outer side of the other side plate. One of the carlines is shown exposed in Fig. 2, and the shape of the carlines is also shown in Figs. 3, 4, 5, 7, 8, 9, 10 and 11. Each carline E at the top thereof slopes from the outer side of each side plate upwardly to a point centrally between the ends of the carline. Each carline E is provided externally with two laterally and outwardly projecting flanges 15 and 15 which are arranged at opposite sides respectively of the carline and extend longitudinally of the carline and along the top of the carline from the outer side of each side plate A to the outer side of the other side plate. As shown in Figs. and 10, each flange 15 projects downwardly, as at 16, at the outer side of each side plate A and abuts against the outer side of the said side plate and thence extends laterally and outwardly, as at 17, over and in close proximity to the top of the car-siding D adjacent the said side plate and to the outer side of the said car-siding. Each carline E is rigidly secured at the flanges 15 thereof by suitably applied bolts 18 and nuts 19 to the side plates A.

By the construction lrereinbefore described it will be observed that the carlines E etflciently tie or connect the side plates A togethenthat each side plate is materially reinforced at its outer side and above the adjacent car-siding D by the adjacent downwardly projectingportions 16 "of the flanges l5, and that the said downwardly projecting portions of the said,

flanges afford a lateral abutment or bearing for the outer side of the said side plate.

The relative arrangement of the parts is preferably such that the flanges 15 where they extend across or transversely of each. side plate are flush'at their upper sides with the top of the said side plate, as shown in Fig. t. Each flange'15 of each car-line E is (see Figs. 3 and l) depressed and somewhat increased in width centrally between the ends of the carlines to form a pocket or depressed seat 20 for the ridgepole F of the car-roof, which ridge-pole extends in the usual manner longitudinally of the car-roof and is arranged centrally between and parallel with the side plates A. Each flange 15 'at a plurality of points between the ridge-pole-neceiving pocket or sent 20 of the carline and each side plate A is depressed and somewhat increased in width to form a pocket or depressed seat 22 (see Figs. 3, 5, and 7) for purlins H of the car-roof, which purlins extend longi tudinally of the car-roof and are parallel with the ridge-pole F and side plates A.

The side plates A, the end beams or rafters B, the carlines E, and the space between the side plates from end to end of the car-roof are covered by sheet-metal roofing which comprises sheet-metal roofing-sections L and sheet-metal caps M, and it will be observed that two sultably supported sheet-metal roofing-sections L extend from over each earline laterally of the said ear-line oaaoei tially central between the sides of the car line,that is between the flanges 15 of the carline,and at the said point has an up wardly projecting side portion 24 which extends longitudinally of the said carline and terminates in a flange '25 which projects laterally of the said side portion over and is spaced from the body of the said rooflngsection, which flange extends longitudinally of the said side portion of the said roofing-section and has a downwardly bentportion 26 extending longitudinally of the flange. Each end roofing-section, as shown in Fig. 6, of course pro ects downwardly, as at 14: at the outer side of the car-siding 13 arranged at the outer side of the adjacent end beam or rafter B of the car-roof frame, but obviously each intermcdiate roofing-section,-that is, each roofing-section bridging the space between two adjacent carlines, has two upwardly projecting side portions 24 arranged over and extending along the adjacent cal-lines respectively. An important feature of our invention is not only the opposite arrangement of adjacentflanged side portions 24 of adjacent roofing-sections L, but such a relative arrangement of said side portions that they abut laterally against each other, and

the provision of a desirable cap M for the said side portions of the said roofing-section, which cap covers and extends longitudiiuilly of the flanges 25 of the said side portions of the said roofing-sections and snugly ongages the outer sides of the downwardly bent portions 26 of the said flanges. Preferably the portions 26 of the said flanges of the said roofing-sections are so tightly engaged by the cap that the application of the cap to the said portions of the said flanges places the said portions of the said flanges under tension, so as to insure the reduction to a minimum of leakage of air or other fluid at the joints formed between said cap and said roofing-sections.

e would here remark that the adjacent side portions 24 of adjacent roofing-sections L and the curve or slope 23 of the said roofing-sections over the carline overlapped in common by the said roofing-sections per- Init a limited expansion and contraction of the said roofing-sections without interfering with the maintenance of a snug engagement between the adjacent roofing-cap M and the downwardly bent portions 26 ot the.

flanges 25 of the said portions of the said roofing-sections.

Ea clrcap M is provided externally and over the adjacent carline E with two laterally and outwardly projecting flanges 30 arranged at opposite sides respectively and extending longitudinally of the cap and resting on the said bodies of the roofingsections L whose adjacent side portions 24 are covered by'the said cap over the flanges of the said carline and over the side plates A, and the said cap is shown extending from the outer side of each side plate A to the outer side of the other side plate, and at the outer side of each side plate (see Figs. 7. 10 and 11) has a downwardly projecting end-portion m arranged at the outer side of the adjacent downwardly projecting end-portions of the said roofing-sections and consequently at the outer side of the adjacent downwardly projecting end-portion of the said carline.

Each downwardly projecting end-portion m of each cap M is attached to the adjacentside plate preferably by means comprising a horizontally arranged bolt 32 and a nut 33. The said bolt 32 has its'head ar-. ranged at the outer side of the said portion of the cap and has its shank extending horizontally through the said portion of the cap and through the adjacent downwardly projecting portion of the adjacent carline and through the adjacent side plate. The said nut 33 is screwed onto the said shank at the inner side of the said side plate, and a washer 34 is interposed between the said nut and the side plate.

By the construction hereinoefore described it will be observed that each end-portion at of each roofing-cap M forms an airconducting passageway 28 which (see Figs. 7, l0 and 11) is arranged interiorly of and extends longitudinally of the said roofingcap and communicates with the external at,- mosphere at the lower or outer extremity of the said end-portions of the said roofing-cap.

The end-portions Z of the roofing-sections L arranged adjacent each roofing-cap M are separated. as at 29, longitudinally of the adjacent side plate A, as shown in Figs. 10 and 11. so that the said passageway 28 in the said roofing-cap is in communication with the interior of the adjacent troughshapcd carline. and consequently the roofing-caps and the carlines are kept ventilated. The space next under the flanges 25 of adjacent side portions 24 of adjacent roofing sections is obviously also in communica-' tion with the passageways 28 formed interiorly of the end-portions m of the adjacent roofing-cap, and air also leaks between each flange 15 of the said carline and the adjacent roofing-section lrandat the seats 20 and 22 tilation of the componentparts of the carroof and the interior of a car provided with the said roof successfully prevents sweating of the said roofing-parts and car-interior and consequently the car is kept in a dry condition.

Any suitable number or all of the carlines E are each provided centrally between the ends of the respective carline with a rivet J which (see Figs. 3 and 4) is arranged horizontally and transversely of the said carline. The said rivet extends between the sides of the said carline and is parallel with the ridge-pole F. The said rivet is embraced centrally between its ends by the eye 35 of an eye-bolt which has its shank 36 pro-jecting vertically upwardly a suitable distance above the said carline. It will be observed therefore that the said eye-bolt is arranged centrally between thesides and centrally between the ends of the said carline and connected to the carline. The said eye-bolt is provided intermediate its upper extremity and the carline with a 'diametrical enlargement 37 which is spaced from the said carline and from the said extremity of the said bolt. The side portions 24 of the roofingsections L overlapping the said carline extend transversely of the said eye-bolt between the. ridge-pole and diametrical enlargement 37 of the eye-bolt. and are respectively offset laterally and outwardly, as at 27, (see Figs. 3 and 8) to embrace the shank.

of the said bolt'below the said diametrical enlargement of the bolt. It will be observed therefore that the roofing-sections overlapping the said carline have their adjacent side portions 24 embracing opposite sides respectively of the said eye-bolt-. The upper end face of the enlargement 37 of said eye bolt forms an upwardly facing shoulder which is overlapped'by an upwardly ofi'setportion 38 of the roofing-cap M which covers the flanges of said side portions 24 of said roofing-sections, and said upwardly offset portion of said cap extends around said eye-bolt and rests on said shoulders Said cap M is provided centrally between its ends with a cap K which forms the body of a saddle which is instrumental in supporting.

three running-boards G and has its top formed by a substantially horizontally arranged plate P. Said'cap or saddle-body K is provided with two laterally and outwardly projecting flanges 40 extending longitu'dinally of and overlapping the flanges of-"theadjacent roofing-cap M. Said cap or saddlebody K (see Fig. 4:) has three seat-forming members 42 spaced longitudinally of the adjacent carline and arranged substantially in the same plane horizontally, and the cen- 5 tral seat-'t orming member extends over and rests on the upwardly otlset portion 38 of the adjacent roofing-cap M and extends around the adjacent eyebolt above the shoulder formed by the enlargement 37 of said eye-bolt. The aforesaid plate P is mounted on the seat-forming members 42 of the saddle comprising said plate, and a nut 39 is screwed at the upper side of said plate onto the shank of the adjacent eye-bolt, which shank extends upwardly through the central seat-forming member 42 of said saddle and through said plate. Upon tightening said nut, said plate and the body of said saddle and the upwardly o tlset portion 38 of the adjacent roofing-cap M are clamped by said nut against the upwardly facing shoulder formed by the upper end of the enlargement 37 of the eye-bolt engaged by said nut, and obviously by this construction is effected the'clamping to said shoulder of said roofing-cap and the running-board-saddle with which said roofing-cap is provided, without any interference with expansion and contraction of the roofing-sections extending an under said roofing-cap. In other words, the

central portion of each rooting-cap M is provided with a running-board-saddle compris ing three seat-forming members it-2 which are spaced longitudinally of said roofing-cap and arranged substantially in the same plane horizontally and carry a plate I over and across which the running-boards G eX- tendf Said running-boards (see Figs. 1, 2, 3, 4, and 6) are shown arranged in the same 40 plane horizontally and extend longitudt nally of and from end to end of the cara'oof. The running-boards are secured at the ends of the car-roof (see Figs. 1, 2, and 6) to and supported from suitably applied brackets I. The running-boards are shown secured to the central seat-forming members 42 of the running-board-saddles by suitably applied bolts It and nuts r, and the central runningboard is recessed at its under side, as at g, to accommodate the location of the eye-bolts and engaging nuts.

By the construction hereinbefore described it will be observed that not only is a joint formed between adjacent side portions or members 24 of adjacent roofingsections L, but a joint is also formed between the outer portion 26 of each flange 25 of each of said roofing-sections and the ad jacent side of the cap M covering said side members, so that said ,side members and said cap are relatively contoured to form joints at the sides of the can between the cap and said side members; that the last-mentioned joints, being arranged at the sides of said cap, are located between the joint formed between said side members and the roofingsections and the external flanges 30 of said cap and consequently spaced from the lastmentioned joint; that a space is formed at each side of said cap below the joint formed between said side of the cap and the adjacent side member of the adjacent roofingsection and that said space is arranged within and extends longitudinally of the cap and also extends from said side of the cap to the lower portion of said side member of said r-oofing'section; that flooding of the carline arranged under the joint formed between adjacent side members of adjacent roofing sections is avoided because any wa- .ter forced or driven at the under sides of the flanges 30 of the cap covering said side members into the spaces formed under the flanges 25 of said side members must be driven upwardly at and past the joints 5 formed between said cap and the flanges of said side members before it can reach the joint formed between said side members, and that any water that may reach the last-- mentioned joint and perchance leak at said joint into the trough of said carline is conducted off by said trough.
