METALLIC ROOFING.

Application filed April 15, 191 1.

T all whom it may concern Be it known that 1, WILLIAM H. KoHR, citizen of the United States, residing at Penbrook, in the county of Dauphin and State of Pennsylvania, have invented certain new and useful Improvements in Metallic Roofing, of which the following is a specification.

My invention relates to improvements in sheet metal roofing, and as its primary object aims to provide a plurality of interlocking tiles or shingles so arranged relatively to each other as to effect when properly joined a serviceable all-metallic roof.

According to the present invention the roofing tiles are of simple construction, re quiring no adjustment. They are light, easily placed and arranged, and when in place they constitute a complete impervious roof. The tiles are preferably of sheet metal; but iron, galvanized or covered in any manner, copper, or any other appropriate metallic substance may also be used. The tiles are fixed to the lathwork, scantling, or any other wooden or iron frame ordinarily employed in the construction of roofings.

The above and additional objects are accomplished by such means as are illustrated in their preferred embodiment in the accompanying drawings, described in the following specification and then more particularly pointed out in the claim which is appended hereto and form a part of this application.

In describing my invention in detail reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a perspective view illustrating the manner in which the tiles or roofing sections are interlocked; Fig. 2 is a cross sectional view on the line 2-2 of Fig. 1; Fig. 3 is a plan view of one of the tiles or roofing sections, partly broken away; Fig. 4: is a section on the line 44: of Fig. 3; and Fig. 5 is a plan view, partly broken away, of one of the tiles or roofing sections before being bent into final position.

Referring now to the drawings by numerals, 1 designates as an entirety a tile or roofing section, a number of which when properly interlocked, constitute the improved roof formation comprising the present invention. Said section in its preferred embodiment includes a substantially rectangular body portion 2, cut away at one end as indicated at 3,

and bent longitudinally on the dotted lines a of Fig. 5. Said section 2, after having been bent upon the line a, is reversely or oppositely bent upon the line 5 of the said Fig. 5 to bring the edges 6 and 7 formed by that portion cut away as at 3, in engagement, one with the other, and forming a flange or seam 8 extending longitudinally of the tile. The section or tile is then bent upon the line 9 of the said Fig. 5 to underlap, as indicated by the dotted line in Fig. 3 the main or body portion of the said section. Again the section is bent, this time upon the line 10 of Fig. 5 to form a transverse seam 11, which seam, the tiles or sections being interlocked, is adapted to overlap the adjacent or interlocking tile. The bend upon the line 10 is remote from the edge 12 of the section to in this manner cause a portion of the tile to extend beyond, as indicated in Fig. 3, the edge of the seam 11. After having been bent in the manner above set forth, the entire tile or section is longitudinally corrugated whereby to cause the tiles or sections, when interlocked, to positively retain their relationship, as well as to effect, when in practical use, proper drainage.

In assembling the tiles, the upper edge of one tile is disposed to underlap the seam 11 of the tile next above, while the tile to the left is disposed to underlap the seam 8. The latter seam, 8, being formed at the apex of one of the corrugations, it is apparent that drainage will be toward the base of the groove or corrugation for an obvious purpose. When assembled, the tiles are fastened together in any suitable manner, preferably at the point indicated at 13, thus forming a serviceable, impervious, interlocking all-metallic roof.

From the foregoing, taken in connection with the accompanying drawings it will be noted that each tile or section is stamped or formed from a single sheet of metal; that the said sheet of metal is bent in the manner above set forth to form the overlapping intersecting seams; and that the tile sections when assembled so interlock as to render the roof impervious.

In reduction to practice, I have found that the form of my invention, illustrated in the drawings and referred to in the above description, as the preferred embodiment, is the most eflicient and practical; yet realizing that the conditions concurrent with the adoption of my. device will necessarily vary,

I desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrific ing a rectangular piece cut from one of its ends adjacent one of its longitudinal edges,

a longitudinal seam formed by first bending the said plate upon a line extending longitudinally of the plate parallel with itsedges at a point equi-distant the longitudinal edges formed by that portion cut away, the said plate being again'and reversely bent at a point'in line with the outer longitudinal edge of that portion cut away, the bend aforesaid forming the longitudinal seam, a

comparatively large transverse seam formed by first bending the cut end of the plate parallel with the plate end at a point in line tioned forming the transverseseam, said transverse seam being made subsequent to the making of the longitudinal scam, the said transverse and longitudinal seams inter? secting at a point adjacent one corner of the completed plate, the transverse seam overlapping the longitudinal seam, the respective seams being adapted for overlapping en gagement with the plate next adjacent thereto, and means fastening the said plates when interlocked, as and for the purpose set forth.

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