RUDOLPH K. TYRAQOF MINNEAPOLIS, MINNESOTA, ASSIGNOR. ro' r. L. YTYRA, or

snrneLn.

My invention relates to stamped metal shingles, such as are usually made in imitation of tile, and has for its object to improve the construction thereof'in the several. particulars hereinafter noted. I

Generally stated, the invention consists of the novel construction, arrangement and combinations of parts hereinafter described and. defined in the claim.

In the accompanying drawings, which il lustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a perspective view showing several of the shingles applied to a roof structure constructed and applied in accordance with my invention; I

Fig. 2 is a section on the line.-2-2 of Fig. 1;

Fig. 3 is an enlarged fragmentary section on the line 33 of Fig. 1;

Fig. 4 is a perspective showing in detail one of the anchoring clips;

Fig. 5 is a view corresponding to Fig. 3

but illustrating a slightly modified form of anchoring clip or means; and

Fig. 6 is a perspective showlng 111 detail the anchoring clip shown in Fig. 5.

Fig. 2 shows two shingles applied to a roof, the said roof being indicated by the character A. Each shingle 7 is stamped from sheet metal, has corrugations running from upper to lower extremity, and is formed at its upper edge with an upstanding lap flange 8'and at its lower edge with a downturned lap flange 9, both of said flanges 8 and 9 preferably being formed Lshaped in vertical section. This adapts the two shingles to be overlapped, as shown in Figs. 1, 2 and 3, and to provide for this overlapping, each shingle, just above its lower edge flange 9, has a raised ridge 10 that overlies the upper edge flange 8 of the neXt lower shingle. Shingles, when thus constructed and overlapped and applied to an inclined roof, will effectually shed water and snow. The flanges 8, in particular, prevent water from backing up under the shingles, even when the shingles are laid on.

a roof with very slight pitch.

As an important feature, the invention is directed to means for interlocking the lower edge of an upper shingle to the upper edge of an immediately adjacent lower shingle. This means may take different forms, but in the several forms, the anchoring'means will anchor the upper-edge of the one shingle to the roof and will serve to anchor the overlapping lower edge of the uppershingle to the roofand to the said lower shingle, without the use of nails exposed to the weather. In Figs. 1 to 4, inclusive, this anchoring means comprises anchoring clips 11 having slightly raised and downwardly projecting anchoring fingers or projections 12. qThese clips 11 are slightly bowed at their ends so that they closely engage thetops of the corrugations 7 of the shingles and hold the fingers 12 over the underlying corrugation in proper alignment therewith and against lateral shifting movements when a shingle nail 13 is passed. through a central portion 14 of each clip and through perforations in the corrugations of the shingles, and driven into the underlyingroof boards A, as best shown 7 in Fig. 3; It will be noted-that the fingers 12 have centrally located longitudinal corrugations 12 that diverge upwardly from the immediately underlying corrugation, for a purpose that will presently appear.

The shingles will be laid progressively from the lower toward the upper portion of the roof. The first or lower shingle will be first secured to the roof in its upper edge by applying the anchoring clips and nails as just stated, care being taken to drive the nails down against the clips but not far enough to crush the corrugations of the metallic shingles. Each shingle, in its down-- turned lower edge flange 9, is formed with perforations 9 through which the fingers 12 of the cooperating anchoring clips maybe freely passed. In laying asecond shingle,

it is first slid upward on the lower shingle in a manner to cause the fingers 12 to project through the perforations 9', and under this upward action, the oblique corrugation or rib 12 will cam or push the lower portion of said upper shingle tightly against the upper portion of 'the lower shingle. hen the upper shingle has been thus anchored atits lower edge, *the clips will be 7 of the nails. This gives a chance tor the circulation of air, which will make the roof cool in the summer and will ver greatly reduce rusting of the shingles and rotting of the roof by accumulation of moisture under the shingles. The lower portions of the shingles may he further clamped down and more tightly secured by hammering or pressing down the fingers 12 of the anchoring clips. In this way, the shingles may be so tightly pressed down and anchored that there will be no rattling or vibration thereof under the [action of wind. The anchoring clips, except for projecting portions of their fingers, will also be covered and hidden from view.

As is evident, these metal shingles may be made of any suitable material. Usually, however, they will be made of galvanized iron and will be painted either before or atter'they have been applied to the roof, so that they will :give a good imitation of tile.

The construction illustrated in Figs. 5 and 6, so faras the'shinglesthemselves are concerned, isthe same or substantially the same as that above described in connection with FigsQl to 4, inclusive, but in this construction, the anchoring clips are in the form of metallic fingers 1,5 that project from and are formed integral with the heads of nails 16. These nails wil1 be driven. through suitable perforations in the corrugations of the shingles and into the roof boards with the fingers 15 properly projecting over the corrugations of the said shingles. Obviously, the fingers 15 will be passed through the passages or slits 9 of said shingles, and the method of laying the shingles will be the same as already described.

What I claim is:

A shingle in the form of a stamped sheet formed at its upper edge with an upstanding lap flange and at its lower edge with a downturned. approximately L-shaped lap nested, said shingle at its lower portion, just 7 above its lap flange, having an opening through which the pron-g' of an anchoring device may be projected as and for the purposes set forth.

In testimony whereof I afiix my signature.

RUDOLPH K. TYRA.
