METALLIC SHINGLE.

SPECIFICATION forming part of Letters Patent No. 336,733, dated February 23, 1886.

(No model.)

To all whom it may concern:

Be it known that I, ALvIN NELSON Moire ROSE, of Clay Centre, in the county of Clay and State of Kansas, have invented certain new and useful Improvements in Metallic Shingles; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying draw ings, which form a part-of this specification, and in which- Figure 1 is a View showing a number of my improved metallic shingles or roofing-plates in position upon a root. Fig. 2 is a transverse section on line x as, Fig. 1. Fig. 3 is a similar view on line 3 1 Fig. 1; and Fig. 4 is a similar view showing a modification of the lock.

Similar letters of reference indicate corre- U sponding parts in all the figures.

My invention has relation to metallic shin gles or roofingplates; and it consists in the improved construction and combination of such a plate, as hereinafter more fully de scribed and claimed.

In the accompanying drawings, the letter A indicates the body of the shingle, which is square or rectangular, and composed of a plate of sheetmetal. This plate has four corrugations, 13, running parallel with the edges, at a distance from the same, and forming the sides of a square, the corners of which are cut off and filled with short corner corrugations, O, the configuration of the corrugations being in this manner an octagon having four longer sides placed in a square, and four short sides at the corners of the same.

One, D, of the upper edges of the shingle is formed with a hooked lock, E, consisting of asharp fold, F, which is bent inward so as to form a hook-shaped locking-flange, and the edge outside of the hooked locking-flange is adapted to be nailed to the board-covering of the roof. The other upper edge of the shingle is formed with a number of corrugations, G, and the edge H of the shingle is turned slightly upward.

The edge I, diametrically opposite to the locking-edge, is folded in upon the under side 'of the shingle, forming a hook adapted to engage the locking-flange of the adjoining shin gle, and acorrugation, .I, is formed parallel with this inwardly-bent edge.

The edge K, opposite to the corrugated and upwardly-turned edge, is provided with a corrugation, L, near the edge, which is bent outward, and is in a plane slightly lower than the plane of the flat portions of the shingle.

Within the octagonal figure of corrugations upon the middle of the shingle are a number of corrugations, the middle one, M, of which is diagonal to the square formed by the long sides of the octagon, and is placed vertical when'the shingle is laid, while the other corrugations, N, are parallel with the central corrugation, andgradnally decreasing in length.

In Fig. at is shown a lockingflange slightly different in shape, but accomplishing the same function, the edge of the shingle being bent inward, so as to form an outer flat portion, 0, through which the fastening-nails may pass, while the edge is curved slightly upward and thereupon inward, so as to form the locking flange, the shape of the flange and location of the same being similar to the afore-described flange, while its mode of being formed is different.

It will be seen that the outer edge at the locking-flange is nailed to the boardcovering of the roof, and that the adjoining edge of the shingle above will engage with its inwardlybent edge the hook shaped locking-flange, and that the downwardly and outwardly bent edge of the shingle will rest upon the edge of the adjoining shingle having the parallel corrugations, the corrugations of the edges fitting upon each other, and the downwardly and outwardly bent edge of one shingle bearing against the upper face of the lower shingle, while the upwardly-bent edge of the lower shingle will bear against the under side of the upper shingle.

The octagonal configuration of corrugations in the middle of the shingle will re-enforce the shingle and form channels for water to be guided downward, and the vertical corrugations will strengthen the shingle and aid in guiding water downward upon the roof.

The free edges of the shingle are at liberty to slide sufficiently to allow for expansion or contraction of the shingle on account of variations in the temperature, while the edges will be sufficiently locked together and will bear sufficiently firmly against each other to prevent any moisture from passing up between the edges.

The nails and their perforations are covered, so as to prevent corrosion of the metal at these points, and in case the shingles are to be used in the same manner as other metallic roofingplates, with their edges united by solder, the upper edges are both formed with the lockingflange, and boththe lower edges are bent inward to form the hooked edges engaging the said flanges, and both the exposed seams are soldered.

Having thus described my invention, Iclaixn and desire to secure by Letters Patent-- 1. A metallic shingle having corrugations formed at its middle parallel to its edges in the shape of a square, having its corners cut off by short corner corrugations, and having a diametrical corrugation and shorter corrugations parallel to the same, as and for the purpose shown and set forth.

2. A metallic shingle having one upper nailing edge and an upwardly and inwardly bent looking-flange parallel to and inside of the nailing edge, having one upper edge formed with a number ofparallel corrugations, and bent upward at the outer edge, having the lower edge opposite to the corrugated edge bent outward in a plane below the plane of the shingle and provided with a corrugation parallel to the said edge, and having the other lower edge bent downward and inward to form a hook-shaped edge and provided with a corrugation parallel to the same, as and for the purpose shown and set forth.

3. A metallic shingle having an upper edge bent slightly upward, and provided with corrugations parallel to the same, having the opposite lower edge formed with a corrugation and bent outward in a plane slightly below the plane of the shingle, and having the other edges formed with locking-flanges, as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto atfixed my signature in presence of two witnesses.

ALVIN NELSON MONTROSE.
