1'? HM /mm it "my rmiccrri:

Bo it lmmvn that l DAVID W. Haunts vvon'rir, a citizen of the United States of i-ium'ira. residing at- Detroit. in the county of i aync and State of Iiiichigan, have in vented certain new and useful improvements in Outside Car-Roofs, ot which the following is a specification, ro'lerence being had therein to the accompanying drawings.

The invention relates to car roofs of the type lzuovvu as outside roots. in which the board covering is \veatheuproofed by an overlaid sheathing.

t is the ohject ol the invention to provide greater flexibility or freedom o'l movement of the metallic sheathing in relation to the board covering and at the same time to securc better \veathcriroofing qualities than in constructions heretofore used.

T this end the invention comprises various features of construction as hereinafter set forth.

In the drawings:Figure 1 is a side elevation of a portion of a car root to which. my ii'nproveniants are a pplied; Fig 2 is an end eievi-ition thereof; Fig. 3 is an eulargei'l side elevation showing the joint between adjaccnt sheets; Fig. t is a cross section taken on line m w of Fig. Fig. is a cross section tin-(nigh die ridge; Fig. 3 a plan view of a portion of the ridge; 7 is a perspective view of one of the members shown in 3; and 8 is a, View similar to 4t taken ona slightly different plane ano showing the spiral engaging}; flanges.

In the present state of the art it is usual to provide car roots of the ty ie above rcferrod to with attachment means hotween the weather n'oofing sheathing and the roof which will permit a certain degree of independent niovei'nent. It is necessary, howeven to securely fasten the sheathing to the hoard root at distributed points, and experionce has demonstrated that thesesocuring points are the places where the sheathing is first broken or torn. With my improve-d construction I avoid this result by providing a practically continuous securing or holding down means extending around the margin of the sheets, while the required tlexihility is scoured by a slidable and fiexiblo engagem nt between individual sheets and the securing means.

In detail, A is the siding, B the, fascia and overl ie this hoarding.

.C the side plate of a car body of usual construction. D is the board roofing and E are the metallic weather-proofing sheets that Those sheets E are secured to each other so as to permit independent movement to conform to tho \veav ing in the car frame, preferably by providing their adjacent side edges with spiralshaped flanges F F telescopically engaging each otheix At the ridge the sheets are provided with upstanding flanges G covered by ridge, caps H, and which are held down by the saddles I for the running hoard secured by central holts J passing between the flanges G of the sheets.

To secure the roofing" sheets down at the "eaves I provide longitudinally-extending metallic strips K which are rigidly secured to the fascia and plate by nails or other socuring means L. The upper edges of these strips have a hooked engagement with the outeredges of the sheets, preferably by forming upon each a spiral flange M, which flanges ma he engaged with each other by either a relative rotary or a telescopic movement. The strips K engage the sheets not only at tho sides of the car but also across the end thereof and consequently the entire perimeter of the metallic coa'ering held down upon the car :t'ranie.

To avoid cutting down the side clean anco of the car, the spiral flanges M are arratjet above tho fascia and within the plane of the outer face thereof. To this end the strips K are preferably bent to an angular cross section, each being provided with a flange K which overlies the top of the fa ia', the adjacent ends of said flange abutting against each other. The spiral flanges 1 i and M of tho sheets i'orin weatherproofing joints throughout their extent, but at the corners a spaceis left by the termination of these flanges which requires further \veathorproofing. This is protonably accomplished hy an angularly bent strip N, which lies lienoath tho abutting, edges of the strips K and which extends upward from the top of the fascia and also above tho roofing board. the inwawily-extending llangc N thereof being of suiiicient extent to prevent all danger of leakage. it still further \vcathcnprooling device is provided which consists in a cap member overlying the joint hetvvcrn the abutting ands of upon the, strips the strips and erieending beneath the ends of the flanges F and This cap is secured position without perforaticn therein by a. belt P, which passes thrcugh vex tical aperture in th fascia, and; ics head in engagement with a recess in the can. bar-- in an enufiranee slcii irem {he inner end reef,

e' ai a'li s rucricn as i'lescribed, ii; will. be undeisixmd that the metallic sheathing is cempleiicl \veaLher-prcofed: first, by the engagementef the flanges l and i of adjacent shes-issccond, by the engagement cf the flame" r with the ccrrespending flanges cf the sari ll; iillfll, by the underlying strip JPiu 3;; the joint between the strips K; and fourth, by. the caps O overlying these juinis. It will also be understood that ixhe separate sheets are free to ineve inde pcndenily of cach other and cf the car body and are not fixed in pesii iun at any point throughout their extent. Thus'a't the saves the shecis are free tesiide lengitiulinally ii and also is more align-- larly in relation 0 said strips by the fiexing cf the engaged spiral flanges, At their side edges the adjacent: she are free to more independently by a longifibudinal slid ing nievenient oi the flanges F and F and angularly by a flexing cf said flang At she ends oi the car there is a similar pi vision for lengitudinal sliding and flexing movement in relaiicn to the strips, while at the ridge tin sheets are also free to more limitedly beneath the saddie blocks 1.

To limit the in'wement of the sheets, thc cap member 8 performs the additicnal fnnc sicn (if a stop between the ends of the spiral flanges Suiiicient clearance is provided between the ends 01 these .i'iai'iges and the stop to provide the necessary freedom of the sheets, but a permanent displacement or creeping of "the sheets frcm normal pcsi-' ma am tion is prevented. FUIElRQIEIiOIQ, the Stops are themselves firmly held from displacement by the bolts P so that they cannot be torn off by any ordinary stress in which the roof structure is subjected,

What I claim as my invention is:

l. In an outside car roof, the ccxnbinaticn niiifh roof boards and fasc a arranged to form a longitudinallyestending rabbet, of roofing sheets supported on said reef beards having spiral. cave flanges cngaging said rabbet, securing strips having cumplemeat-arr spiral flanges telescopica l engaging said cave flanges and attached to said fascia, said slxrips and flanges being cut away at their ends, stop members arranged in the cut-away portion 'Jf said flanges, wcaflier-proofing angle strips overlapping the adjacent ends of said securing strips and beneath said stops, and a bolt for securing said step to said fascia, engaging; a. recess in the former and passing through the lat ter and overlying said angle strips.

In an outside C21 roof, the combination with roof boards and a fascia, of roofing sheets supported upon said roof boards provided with flanges extending over said f [any fanges and attached to said fascia, and combined Weather-proofing caps and stops bridging the joints between adjacent securing strips and arranged between the ends of said flan of adjacent sheeis, said combined Weaiherprocfing caps and steps being secured to said fascia by a means extending substantially Vertically tl'irough said fascia and Within said other member.

In testimony whereof I a my signature in presence of two witnesses.
