.Application November 16, 1935, serial No. 50,016

claims. c1.10s13) Our invention relates to roof construction of the type involving panels of sheet metal or other l suitable material, and it is the object of our inwhereby the roof m its nmshed form is effective for preventing the passage of heat therethrough and is of such structural strength as to withstand the pressures likely to be applied thereto by the wind or by a load of snow, and whereby the separate panels asthey come from the factory are of such strengh as to keep their shape in shipment so as to be capable of fitting readily into interlocking engagement with the adjacent panels for the formation of the roof.

`25, It is another object of our invention to provide an improved form of ridge member adapted to have intertting engagement with the uppermost tiers of panels at opposite sides. It is another object of our invention to provide an improved form of eaves member also adapted to have interttin engagement with the adjacent panels.

It is one of the objects of our inventlonto provide an improved arrangement of supporting and attaching means for holding the panelsand other parts rmly in position.

It is another' object of our invention to improve roof construction ont this type in sundry details hereinafter pointed out. 'I'he preferred means by which we have accomplished our several objects 40 are illustrated in the drawing and are hereina ter specifically described. 'I'hat which we li e to be new and desire to cover by Letters Patent is set forth in the claims.

Referring now to the several gures of the drawing, in which corresponding parts are indicated by the same reference characters, I0 indicates the side wall of a building having a top plate II secured thereon longitudinally thereof. l;`

The wall I0 as shownin our drawing is of the type disclosed and claimed bylour prior application Serial No. 758,843, led December 22, 1934,

4the top plate I I being secured in position upon the wall by means of hook bolts I2 of the type 10 disclosed by said application. 'I'he framework of the roof comprises aplurality of rafters I3 which are shown in the form of channel bars on edge,

the rafters ybeing seated at their lower ends against vertically disposed plate portions Il. In- 15 wardly'directed plate portions Iii extend underneath the ends of the rafters, tonguesl being cut from the plate I5 at intervals therealong and bent upwardly into engagement with the rafters and secured in position by means of bolts I1. zo The oppositely disposed raftersv I3 at opposite sides of the building are rigidly connected by tie y members I8 'of any approved type.

At the lower edge of the roof at each side of the building, we haveprovided an eaves member 25 I9 of sheet metal supported at its upper edge by a straight inwardly directed flange portion 20, upon the inner edge of which is formed a boxlike structure comprisingange portions 2| and 22 formed integrally with ,the flange 20. 'I'he 30 vangelli stands linvengagement with an angle bar 23- mounted in crossed relationship to the rafters I3 at their lower` ends, being held in position by means of bolts 24. At a point spaced downwardly a substantial distance below the l3g;

supporting ange 20, the sheetv metal is turned 'downwardly to provide a facing member 25 and thence inwardly so as to provide a horizontal panel portion 2B and then downwardly to provide a flange 21 which is rigidly secured by any suit- 41)v able means to the outer face .of the wall I0.

The principal portion ofthe roof is made up of a series of similar panels 28 of sheet metal Y' each having an inwardly directed straight ange 20 and integrally formed flanges 2I and 22 in 45 box arrangement as is described above in connection with the eaves member I9. At their lower edges, each of the roof panels 28 is bent inwardly and backwardly so as to provide a channel 29, connectedwith which there is a straight 50 inwardly directed supporting flange 30 having a box-like structure formed-on its inner edge comprising ange portions 3|, 32 and 33, as is best seen -by reference to Fig. 2. The box-like structure at the lower edge of the lowest roof panel 55 28 is adapted to t snugly within the box-like structure vformed at the upper edge of the eaves member I9, and the box-like structure at the upper edge of each of the roof panels 28 is adapted to receive snugly therein the box-like structure formed at the lower edge of the next higher panel 28, the roof being formed of a series of interfitted panels 28 each of whichoverlaps the panel member next below. The interfltted box-like structures are secured to the rafters I3 by means of hook bolts 34 which are tightened against the edges of the flanges 22 and against the top faces of the flanges `33, such flanges 33 being distorted slightly by the pressure applied through the hook bolts so as to hold the flanges 33 firmly against longitudinal movement, the parts being-thus held very strongly in position.

For supporting the roof panels 28 in their operative position as described, we provide shelf angles 35 secured in position across the rafters by means of bolts 36 in position to engage the bottom faces of the supportinganges 20. f i

At the angle of the roof, we have provided an improved ridge member 31 also formed of sheet metal bent along its central line to provide panels 38 and 39 at opposite sides. Each of said panels is provided with a channel portion 40 at its lower edge from winch inwardly extending straight .flange portions extend having'inside box structures formed thereon Yas above described in connection with the panels 28.

For insulating the roof and for strengthening the construction, we have provided rigid insulation board members 4| upon the inner faces -of the panels 28, 38 and 39, layers 42 of asphalt emulsion being interposed between the insulation boards and the faces of the panels. As is best shown'in Fig. 2, the boards 4I and the-layers of emulsion 42 are of such thickness as to nt snugly within the channels 29-40 of the members wherebyl the channels are protected positively against collapse. The upper edges of the insulation boards are secured in position by means of bolts :43 extending through the boards and through the sheet metal of the panel. By the use ofthe rigid insulation boards 4| secured in position both by the layer of ,asphalt emulsion and also by the mechanical means as described, the panel members are very greatly strengthened so as to be enabled to keep their shape during handling and shipment from the factory so as to ilt without diillculty in the desired interlocking engagement with each other when applied in operative position upon the framework. Similar rigid insulationboard members 4Ia are secured f by layers 42 of asphalt emulsion and bolts 43 on other at an inwardly spaced point. By this arthe inside faces of the eaves panels between the supporting flanges and the facing portions 25 of said panels.

-By the arrangement of the supporting anges 20 and 30 in engagement with each other and both extending straight from the panel to be supported to the face of the rafter I3, the construction is given such strength as to enable it to withstand the pressure applied -thereon by the wind or by a load of snow, particularly when such structure is reinforced by the shelf angles A23 and 35 as above described.

y At their vend portions, the several panels are connected preferably in the manner shown in Fig. 3, comprising inwardly turned flange portions. 44 which are arranged in spaced relation 4to each other at the outer faces of the members but which stand in snug engagement with each rangement, a channel is provided into which a calking member 45 is inserted for effecting the desired tight joint .between the parts.

While we prefer to employ the form and arrangement of parts as shown in our drawing and as above described, it is to be understood that our invention is not limited thereto but that changes may well be made in the form shown without departing from the spirit of our invention.
