the following is speefcaton Y Y This'invention'relates to'` flexible metal @roofs for freight carswherein the "metal roof sheets ,extendffroin eavestoridge'land are .loosely secured `at the ridge `and eaves to -ik-.he "roof substructure, and adjacent roof 'sheets are :connected nonrigidf standing seams or joints.

"Trhe` objects of the invention ,arey to prevent tearing 0f the' roof sheets-n Service, to .dol away with holes ,through the roof v.sheets for the v'securing means, andto provide forthe convenient removal and replacey mentof worn and-damagedroof sheets, and

to maintain the joints .between the roof sheets tight `Vunder 'Service kconditions'.

e In.y the drawings, the invention isshown applied to a car having a lWooden rooffsubstructure consisting'of roof boards` 11 supridge piece 13, bntthesubstructure may be constructedin any manner desired of either wood ,or metal. The roof sheets ,14 are ar- `ridge are arranged in alinement'crosswise of the car, and the battens on each side of'the car are in alinement and meet at the ridge.

The ridge ends of the roofsheets are slightly convex, and the middle points of the .curved extremities of opposite roof sheets nearly touch, each other at-the ridge lines `midway kThe .sides and ridge endf of each roof sheet are provided with upstanding flanges 16 with inturnedextremities'17 which vslope down the body portion', of the sheet. The

side Aflanges of ,adjacent roof sheets are covered by sideseamcovers 18 ,which are supported on the battens 15. These side'seam covers have side walls 19 which are turned in at their bottoms. and lthe inturned edges 2O of which are hookedunder the extremities 17 of the side flanges of adjacent roof sheets, as shown iinFig. 3.' This construction provides a loose but watertight connection or joint between the sides of adjacent roof sheets. The invention is-not restricted to this side seam construction, and any suiiciently exible searnor joint for connectingv the roof sheets along their sides may be used.

The eaves ends of the roof ysheets are f i ported at theirends on a side platev 12 and strips 23, as shown in Fig. 2. The flashing Strips are nailed or otherwise secured along the eaves of the 'car between the battens. Angle-shaped eaves clips 24: are secured to the side ofthe car below the ends of the roof sheets, withV their top legs projecting inwardly over the eaves ends of the roof sheets 14 and side seam covers 18 to holdthem down. The eaves clips are .detachably secured to the fascia board 25 by bolts, and may be quickly removed and replaced when desired. They rest loosely upon the roof sheets without clampin them, so the roof sheets are free to move oth lengthwise and crosswise of the car at the eaves. The invention is not restricted to this means of securin the roof sheets at the eaves, and any sultable method for loosely holding the eaves ends of the roof sheets may be used.

The ridge ends of the roof sheets are covered by ridge seam covers 26 which are inverted channel-shape, their side walls 27 having outwardly extending flangesl 28 which rest on the roof sheets. length the side wallsp27 of the ridge seam covers are provided with inwardly projecting semi-cylindrical bosses 29 extending from top to bottom. The two opposite bosses 29 of each ridge seam cover are adapted to bear against the inturned extremities 17" of the ridge end flanges 16 of the underlying oppositely disposed roof sheets, and thereby the roof sheets areretained in position on the roof substructure against sliding down. The roof sheets are free to pivot or swing on the bosses 29 and can thereby accommodate themselves to the distortions of the substructure which occur in service.

l The ridge ends ofthe side seam covers 18 and the ends of the ridge seam covers 26 are secured in position by square corner caps 30, the side walls 31 of which arerecessed to fit over the seam covers'. These corner lcaps are bolted to the ridge pole by bolts 32 which also secure the running board saddles 33 in position. The running board saddles rest on the side seam covers .18 and battens 15. The running boards 34 may be secured to the saddles in any suitable manner. The weight of the running board saddles and running boards is not carried on the roof sheets, `which are freely movable under the side and ridge seam covers within side walls thereof.

In the modified form of con struction shown in Figs. 6 and 7, the ridge flanges 35 of the roof sheets 14 are straight insteadof being curved, and the side walls of the ridge seam cover 36 have their lower edgesl turned in and bent up to form trough-shapelanges 37. The inner walls of the troughs 37 are curved in so that the troughs are wider at themiddle than at the ends. The middle pointsof the inside walls of the troughs 37 are adapted to `the roof* sheets 1n them to move aroun to accommodate themselves to thedistortions Midway of their the limits of the contact with the ridge flanges of the underlying 'op ositely disposed roof sheets and thereby orm a pivotal support or fulcrum on which the roof sheets may bear.

In the modifications shown in Figs. 8 and 9, the ridge flanges 38 of the roof sheets are provided with inturned flanges which are inwardly" curved from their ends to the midline of the roof sheets. The side walls of the seam ucovers 39 have straight inturned flanges 40 ada ted to bear against the middle points of the anges 38, and thereby to retain said points of contact of the substructure in service'.

It is evident that other modifications of the ridge construction can be made without departing from theinvention, and this invention is not restricted to any 4one of the arrangements shown and described.

What I claim as my invention and desire to secure by Letters Patent is:

1. A flexible car roof, comprising -roof sheets4 having upstanding4 flanges Vat their ridge ends, the Ilan es of adjacent sheets a preaching each ot er more closely at t e middle than at the corners of the ridge ends of the sheets, ridge seam covers straddling the ridgJlanges of oppositely arran ed roof sheets, said seam covers having si e walls adapted to touch said ridge flanges at their middle points only, and means for retaining said ridge covers in central alinement on the car.

2. A flexible car roof comprising roof sheets oppositely arranged on'each side of the rid e and having upstanding flanges at their ri ge ends, the ridge flanges of opposite roof sheets curving toward each other at .the middle of their length, said ridge flanges having inturned top margins, ridge seam covers straddling the ridge flanges of oppositely arranged roof sheets, said seam covers having side walls provided with pivot bearings for said ridge flanges at their middle po1nts, and means for retaining said ridge covers on the car, said ridge covers having outturned flanges along the bases of their sidewalls which bear upon the roof sheets.

3. A flexible car roof comprising loosely connected roof sheets havin outwardly curved ridge ends, upstanding a glace while permitting nges along said ridge ends, ridge seam covers of inverted channel-shape covering said flanges, .the side walls of said ridge seam covers having cylindrical depressions at their middlepoints constituting bosses adapted to bear against the curved ridge `flanges of said roof sheets.

4. A flexible car roof comprising a series of pairs of oppositely disposed roof sheets extendin from eaves to ridge and loosely connecte along their side margins,l the ridge vends of said roof sheets being' curved out'- bear against said flanges near their middie Wardly. and provided with marginal anges, points, whereby vsaid roof "sheets 'can pivot 10- the middle points of the roofsheets of each on their midlines against each other and pairbeing loeated inproximity to each other, against said inwardly projecting portions of xsaid `pairs of roof sheets, said ridge seam ridge. seam covers over the ridg'e anges'of the ridge seam covers.
