To aZZ whom it may ooncem'.'

Be it known that I, JAMES MCQUEEN, a citizen of the United States, residin at Clifton, in the county of Passaic and tate of New Jersey, have invented a certainnew and useful Improvement in Roofs, the following is a' specification. y

The invention relates to sheet metal roofs and is designed particularly for the roofs of railway freight cars and like structures.

The obj ect of the invention is to provide a roof of sheet metal, economically constructed and easily applied, which shall beeminently strong and durable and in which the danger of leaks is avoided.

Another important object is to provide a shallf avoid the use of solder and be leak roo A further object is to provide means for securing the roof sections reliably to the carlines or roof frame, and for joining the running board saddles to the sections an carlines without puncturing the roof for the reception of bolts or like fastenings.

Another important object is toV provide means for sealing effectually the ends of the roof-joints and for protecting the nails or other fastening means by which the valance or depending flanges of the sheet metal is secured to the fascia boards at the sides and ends of the car.

y The invention consists in certain novel features and details of construction and arrangement by which the above objects are attained, to be hereinafter described and claimed.

The accompanying drawings form a part of this specification and show an approved form of the invention as applied to a freight car.

Similar reference numerals indicate the same parts in allthe figures.

Referring to the drawings,`20 is the ridge pole of the car, and 21 the purlins or longitudinally extending roof-beams, and 22 are the carlines or transverse rafters, 23 the runnin'gboard, and 24 the runningboard saddles.

The roof is composed of wide strips of sheet metal 25VeXtending transversely of the can and joined at their adjacent margins,

with their ends overlapped upon the lsides and endsl of the car inv a narrowvdepending flange lor valance 26.

lThe joint between adjoining ysheets or roof-sections is formed by bending or folding the margins as shown in Figures 5` and 6, in which the margins of one section are at a right angle as at 2 7, then, downwardly at 28, and thence again upwardlyas a vertical flange 30 and forining a channel 29. The margins ofthe next sections are bent upwardlyat v31 and'then downwardly atk32to form the interior channel 33 and terminating inthe depending vertical flange 34.` 1nI applyingthe sections together the sheet bearing the upwardly extended flanges 30 is laid in place on the carlines and an adjacent section bearing the depending flange 34 is lowered with such liange received in the channel 29, and receiving the fold 27 and 28 in its channel 33. The flange 30 is then folded over and down as at 4l to inclose completely the portions 31 and 32 of such adjacent sheet or section and lock the sections firmly together. The next adjacent section is similarly joined, each alternate section being equipped on both margins with the vertical flanges 30, and the intermediate sections bearing the downwardly extended flanges 32. The joints thus constructed may be pinched to bring their parts into close relationship and it will be noted that the entrance of moisture is effectually prevented by the tortuous vertical lpassages it must follow to reach the under face of the roof. The joint is preferably further protectedby paint applied as usual, iilling the narrow interstices between the upper surfaces of the sections and the de- .pending portions of the joint.

At the ends of the sections the valance 26 vlies upon the upper margin of the fasciaboard 35 and is nailed thereto as shown in Figures 7, 8 and .9. The valance is cut verticallyfor a short distance as at 36 and then longitudinally in each direction from the upper end of the cut 36, as at 37 to form wings 38. The holding nails are driven adjacent the notch produced by forming the wings, and the latter are then folded over the nail heads; in the vertical channels 39 thus producedY are received the inwardly bent folds of a strip or button 40 Iwhich covers the notch in the valance and is firmly held in place by ii'attening the bends by blows of a hammer or otherwise. The side margins of the end sections are similarly secured to the ends of the car as shown in Figure 3.

To seal the ends of the joints between the sections against the entrance of moisture, the portions 30'and 41 of one section are extended as fiaps 42 and 43, and a tongue 44 of sheet metal is nailed to the fascia-board below the jointa see Figure 13a which is folded; 'upwardly to cover the nail heads and the joint between the flaps?. and extends upwardly beyond the joint. The flaps 42 Vand 43 are then folded upon the'tongue? as in Figure 14, the projecting end of the tongue is then folded down upon the flaps as in Figures l5 and i6.

The joint-end may be left in this condition but it is preferablevto pinch the aps and tongue together, as shown in Figures 17 vand 18? or otherwise close the interstices. Thus closed, moistureis effectually excluded fromr they ends of the joints without requiring the use' of solider.

v AThe nails at the'buttons 40 attach thereof sections securely to the eaves and ends of the 4margin of one cart andthe roof is held to the carlines 22 at intervals by anchors 45 of sheet metal, as shown in Figure l0 in which the folded upper portion 46 isengaged in the joint of the roof sections by inclosing the portions 27 and 2S and extending downwardly between the portions 27 and 3l, and thence downwardly on one face of the carline7 beneath the latter and upwardly on the other face where it is fastened to the carline by nails 47; This mode of fastening avoids the use of bolts or nails extending through the roof.

is cut vertically as at 43 to facilitate the slight bend required above the ridge-pole 20 in conforming to the inclines of the car roof,

At the centre of each joint the portion 30 see Figure l2, and two fins 49 are left standingvertically when the portion 4l is folded down in forming the joint as above described. Each runningboard saddle is grooved longitudinally at 50 and is also provided with a slit or saw-kerf 51 extending vertically from such groove. rlhe latter receives the-roof-joint, and the tins 49 extend into the saw-korf; the saddle is secured to the sections by bolts 52 extending transversely through the saddle'and fins 49.

It will'be observed that the car roof thusl A constructed has no openings leading from the exterior to the interior,-and consequently the danger-of leaks is eliminated. Soldering is not required, and painting affords all theprotection necessary in resisting the action of the elements. The structure is strong and dura-ble and eminently simple and economical. f

Yifrlt'hough the inventionisvshown and described as applied to freight-cars, it will be understood that it may be appliedy to any structure to which it may be adapted, and

that modifications may be made as required in such adaptations.

l claim 1. In a roof consisting of sections of sheet metal, the joint described comprising `on the sections at suchjoints, runningboard saddles downwardly upon itself and eachrhaving agroove adapted to receive one 'f of said joints, and a kerf extending Yfrom such groove and adapted to receive said Ems,

and fastening means extending through said saddle and fins.

3. In a roof consisting of sections of sheet metal having interlocked joints at their margins, a fascia board, oppositely located laterally extended flaps on one of said sections at the end of such joint, and a sheet metal tongue on said fascia board below such jo-int, said tongue adapted to be folded upwardly and inclosed by folding said ila s thereupon and thence downwardly upon t eexterior of said flaps to seal the end of such joint.

4. -In a sheet metal roof having a valance extendino' downwardly upon the structure to be roofe said valance having a Vertical cut and lateral cutsextending oppositely therefrom to form bendable wings, fastening means extending throughsaid Valance and intolsaid structure adjacent said wings and covered by folding saidv wings outwardly upon said means, andl a strip of sheet metal folded inwardly upon itself at its ends, adapted to engage in the folds of said wings andfinclose the latter and cover the notch in said valance produced by the folding of said wings.
