ROOFING.

Specification of Letters Patent.

' Patented Aug. 2, 1910.

Application filed October 30, 1907. Serial No. 399,815.

To all 'whom it may concern:

Be it known that I, JOSEPH L. M. DU Form, of South Boundbrook, in the county of Somerset and State of New Jersey, have erings and more particularly to those in which shingle strips '(50 called) of relatively waterroof material are employed and are ,over apped one upon the other to produce an effect similar to that produced by wooden shin les or metal or mineral tiles.

The object o the invention is to provide certain improvements in such? roofings by which the roof will present an attractive appearance-and by which the nails or fastenings may-be covered from exposure to the elements.

To this end, shin le strip havin rate and provide the invention consists in. a

an edge which is serwith oint-s, the exbent under and secured by nails or other fastenin'gs so that said fastenings may be covered by bodies of the points or projections. For convenience, the points 'or projections are preferably scored transversely or otherwise rendered more flexible near their extremities to enable them to be bent accurately along a line parallel to the general direction of the strip.'

As a further refinement of the invention, the serrated edge of each strip may have spaces between ,the bodies of the oints or projections to receive the extremities of the points or projections of the superimposed strips to enable the extremitiw of such points or projections of'each strip to be bent under the spaces between the points or projections of the strip therebeneath.

Referring to the accompanying drawings,-Figure 1 illustrates a portion of a roof which is covered with a roofing embodying my invention. Fig. 2 represents .a section on the line 22 of Fig. 1. Fig. 3 represents a portion of one of the shingle strips. Fig. 4 represents another embodiment of the invention and illustrates a portion of a roof covered with my improved shingle strips. on the line 5-5 of. one of the strips.

The roofing or roof covering, as a whole,

Fig. 5 representsa section Fig. 4. Fig. 6 represents.

strips indicated at .strips, in consequence of devices 0 are 10 11 and 12. Each strip is formed-of a suitable foundation material such .as felt or the like, which is thoroughlyimpregnatedwith a suitable waterproofing material such as asphaltum, oil, pitch or other suitable substance. In addition, each strip may be faced with a suitable water-proofing or finishing material. Each strip is relatively flexible and may be wound in rolls for transportation.

One edge of each strip, as at a, is straight,

whereas the other. edge is serrated or 1ndented to provide a plurality of teeth, points or projections b, which may be of any suitable, convenient or attractive shape. In Fig. 1, the teeth or projections have the shape of acute angles'so that, when the strips are overlapped, the point of one tooth may substantially register with the re'ntrant angle between the two teeth of the adjacent which the roof appears as though it were constructed with diamond-shaped tiles or shingles. Each of the teeth I) is transversely scored, weakened or rendered more flexible as at b, so that the extremity of each point or projection may bebent along a line which is substan-v tially parallel with the general direction of the edge of the strgpwith the extremities b lying under the b jections. V I p In laying the roofing, a strip is placed upon the support or foundation with its under face upward and with its points projecting toward the roof tree. The fastening then driven through. the points into the foundation or support of the roof. The strip is then swung upwardly to bring the outer face of the strip uppermost, the bending of the points occurring along the scored or weakened lines I) so that the bodies of the points or projections cover the fastening devices, as clearly shown. en the next strip is. secured in place, the extremities of the points are preferably caused to substantially register with the reentrant angles of the strip therebeneath, so that, when the second strip. is finally bent upward,

ies of the points or proa diamond eiiectis produced. When the roof is completely laid, the fastenings are all covered and invisible.

As previousl stated, the particular shape of the points 0 projections is immaterial, as almost any desired efiect may be produced. In Figs. 4:, 5 and 6, the strips, which are indicated at 13 14 and points, the sides of which converge toward These points or projections ey are separated as shown by the spaces at, the edges of the spaces being arranged in a line parallel to the general direction of the edge of the strip. The extremities d at each point, which are of the same width as the spaces cl, are provided with transverse scoring or weakening lines (i In laying the strips, the points d of a strip are inserted under the spaces d of the strip therebeneath, until the scored lines 03 register with or are coincident .with the edges of the spaces 45. The nails or other fastening devices are then driven through the lower strip and through the points thereunder, and the upper strip is then bent upwardly along the scored lines (i to lie flat upon the preceding strip. The next .strip is secured in place in the same way. In this way, not only are the points or projections secured by the nails, but each strip is also secured in place by nails which pass through its body in proximity to the spaces at.

It will be seen that the projections of each strip have relatively wide base portions and narrow outer end portions which are bent under the base portions, and secured by fastenings which are concealed by the base portions. The bends thus formed impart stifl ened outer ends to the projections, said outer ends and the edges of the base portions collectively forming uniformly shaped symmetrical figures or panels, as shown in the drawings. The form of these panels is made permanent by the bends which so stiffen the outer ends of the projections that they cannot be bent or warped by elemental action, a result which would be likely to occur if the outer end portions were not thus bent adjacent to the points where they are fastened. I

While the covering herein-described, is particularly desirable for roofs, yet it is applicable for various other purposes, such as covering the sides of a building etc., and hence in using the term roof covering, I mean to include thereby coverings for various other analogous purposes.

Having thus explained the nature of my 15, are provided with the extremities.

are indicated at of the projections g said invention and described a way of makwhich are curved and i mg and using the same, although without attempting to set forth all of the forms in which it may be made or all the modes of its use, I declare that what I claim is l. A roof covering consisting of overlapping strips of relatively flexible material, each strip having along one edge a plurality of projections with relatively wide base portions and narrow outer end portions which are bent under the base portions, and fastenings inserted in the bent under portions and concealed by the base portions, the bends of the projections forming stiffened outer ends which are in alinement with each other throughout the length of the strip, each strip being laid with the stiflened ends of its projections coinciding with the inner ends of the recesses between the projections of the next strip, whereby the edges and stiffened ends of the projections collectively form uniformly shaped symmetrical figures or panels, the form of which is made permanent and free from liability to distortion, by the stifi'ening of said ends.

2. A roof covering consisting of overlapping strips of water-proof flexible material, each strip having along one edge points or projections with intervening spaces, with the extremities of its points bent under the spaces of strip thereunder, and fastenings passed through the bent-under extremities of said points or projections and covered by said points or projections.

3. A roofing strip of relatively flexible material having along one edge a plurality of projections with relatively wide base portions and narrow outer end portions, the inner ends of the recesses between the projections being formed to receive the outer end portions of the projections of an adjacent strip, whereby the end portions of the projections of one strip may be inserted under the next strip at the inner ends of its recesses, and bent over said inner ends.

In testimony whereof I have afiixed my signature, in presence of two witnesses.

JOSEPH L. M. DU FOUR.
