To all whom it may concern Be it known that W,-CARLYLE E. 'LA'rrA and WIL IAM D. Tnomrson, both citizens of the United States of America, residing at Detroit, in the county of \Vayne and State of Michigan, have invented'certain new and useful Improvements in Car-R00fs,.

outside and inside sections or of a plurality vof courses. In this particular, as a .ther distinguishing characteristic of the furinvention itmay be' stated that the same pertains to What may very properly be designated as a single course car-roof, as distinguished. froma double-course roof.

Generally speaking the invention relates to a metallic car roof which possesses ade quate flexibility and required roofing rigid .ity. As components of the structure there are rigid or load supporting metallic plates constituting in the main theprimar'y roofing elements, and associated with these plates are sultable means for forming weather-proof-.

ing joints between the plates, which means are so constructed and arranged that while 'the roof will be maintained weathcr-tight,

it will still possess the requisite rigidity and flexibility to permit the weaving actions of the structure.

In the drawings illustrating an embodiment of the invention,-Figure 1 is a cross section througlna roof embodying our in-- vention; Figf is an enlarged sectional View.

transverselythrough the roof on line y-g/ Fig. 4: through the ridge portion; Fig. 3 is a section taken on line m-w of Fig. 2, illustrating the peculiar construction of the covering means for the plate edges; Fig. 4 is a sectionalperspective view, illustrating the holding-down means for the sheets at the 1 peak; Fig. 5 is a detached perspective view a sectional perspective view, illustrating a modified form of holding-down means for the sheets at the ridge, and retaining means for the cap plates; and Fig. 7 is abottom plan view ct the saddle or sleeper, which supports the running-boards. Fig. 8 is a .plan view of a portion of completed roof,

some of the parts being removed.

In construction, the roof comprises a framework consisting of purlins A, ridgtlapole' B, and carlinesC. D represents t and F thefascia. The car-lines in this particular form of roof extend preferably uninterruptedly over the ridge from eave to cave, and'consist of a body section G, including upstanding spaced flanges H, and a base section I extending laterally beyond the 'fiangs ,'as indicated in Fig. 3.

'As applied to the root, the body sections ofsthe 'carlines extend to the outer face of sections Iextend downwardly and within suitable recesses, such as J, formed within the plates D, as plainly shown in Fig. 2. They are secured; at their lower edges by bolts K.

or peak. Each plate of the series has its marginal side edges turned upwardly,

in g upstanding of the roof.

In Fig. 4 we have shown a holding:down

of the closure for the cap plates; Fig. 6 is usual side'plates of the car, E the siding,'

the fascia, as shown in Fig. 2, While the base i L represents the roofing-plates arranged in two series, one on each side of the ridge the peak the desired flexibility transversely formflanges as M and these flanges are adaptedto abut or extend in means for the ends ofthe plates at the rides in the form of a super-ridge-pole Q, te under face of which is cut away or grooved, forming a continuous longitudinal opening R, within which the upstanding flanges P on the sheets extend, the opening being of, sufiicient width to permit transverseplay of the lates for t-he purposes previously set fort 1,. The ridge-pole in turn is held in place by bolts. S, as indicated in Fig. 2. t

- The'marginal portions of the plates are 7 covered in this instance by inverted troughshaped cap plates T, each extending fromthe save to the ridge, and the upper portion of the groove or, opening cap projecting within asuitable transverse U formed in therulgepole, as shown in Fig. l. Each cap .ex-v tends entirely overthe body portion of its carline and the adjoining sheet flanges, and Q contacts with the plate bodies at a distance from the upturned edges. A space or clear.-

ance, as a, is formed between the cap and each marginal plate flange, which allows relative longitudinal play of the plates under the twisting movements of the roof structure. ,The caps are-provided preferably with marginal flanges V adapted to rest upon the roofing plate bodies, thus forming a tight joint, preventing the driving in of the rain and consequent leakage.

"The lower ends of the cap plates are covered by suitable closures, new, the closures in turn being held up'on the cap plates, and the latter upon. the roof platesby lags'crews'XLwhich extend vertically through the closure, cappiate and carline. u The preferred-form of closure is illustratedmonsisting? of atrough-shaped section a embracin the lower portion of the cap plate, and ormed with a vertical aperture (IF-and a bolt-seat b; and a flat-depending plate section 0 extending over the open end or the cap plate and at a distance below the same, the cap being held in place by the,

lag-screw X. As thus constructed, the rigid plates being preferably attached at their lower ends at'the eaves, provision is made for relative transverse movement and longii tudinal-play of the plates, and the desired flexibility of the metallic roofing is obtained. I j

- In 6 We have'sho'wn a modified form -of holdin -down means for the plates at theirfupperv ends consisting of channelshaped cap plates A, preferably marginally /fianged, at B, and arranged over the peak flanges ofthe plates and intermediate of the transverse cap plates T. The.meet- ..-1ngends of the longitudinal and transverse 3 covercd by a sleeper or saddle C, the under caps, as shown in Fig." 6, are preferably face being channeled out longitudinally and transgersely, as indicated by the referenceletters a? and e, to engage over the cap plates.

The sleeper is held in place by a suitable bolt D, and is adapted to receive the usual running-boards E.

" The sleeper described, as will be obvious,

not only covers the joints between the cap plates, thus preventing leakage, also performs the further function ofholding the several cap plates down upon'the' roof structure, thus dispensing with the necessity of specially prepared devices for this purpose.

'lt-"is to be understood that the intention.v

herein described is not limited to the structure so described and as shown. Many Widely difierent forms of structure can be made and substituted} without departing from the nature and principle of the invention.

Someof'the more important advanta es of the invention may be stated to be as '01- lows: First, the structure is simplified by entirely dispensing with the board covering generally used in roots of the prior art-,and

so in a satisfactory manner; second, there is a material reduction in the weight of the roof as compared with such former strum tures, which means decrease in the dead load of the car as a whole and increase in freightload carrying capacity; tlnrd, the thickness or depth of the entire roof structure is greatly decreased, thereby providing additional space within the car for the treight;
