UNITED STATES PATENT OFFICE NORMAN P. HABSHBERGEB, OF CHICAGO, ILLINOIS, ASSIGNOB TO BAKELITE BUILDING PRODUCTS CO. INC., 01' NEW YORK, N. Y., A CORPORATION OF DELAWARE ROOFING MATERIAL Application filed Kay 21,

This invention relates to roofin material and, particularly, to strips of roo ng material which have one edge serrated so as to provide a more pleasing appearance to-the roof. One form of the serrations which I have illustrated in explaining my invention is that of a portion of a hexagon; but the invention relates equally as well to other figuges which may be formed by these serrated e gas.

The invention has for one of its objects a method of producing figures on the roof by a combination of the serrated edges of the shingling strips with definition lines or lines of demarcation on the strips which produce certain sides of figures and, at the same time, to reduce the amount of shingle material necessary to properly cover the roof and to roduce the desired figures. Another obect of the invention is to provide means for more conveniently laying thestrips and for. conveniently and efiectively locking or clampin them down, so that the exposed edges Wlll not be raised by war ing, wind or otherwise. A further object o the invention is to provide strips with serrated edges which may be laid horizontally or at an inclination to the eaves of the roof.

Of the accompanyin drawings, Fig. 1 is a plan view of a roll of finished stri s of shingle material which embody the eatures of my invention, with an end portion unrolled and flat; Figt2 is a plan view of these strips after they have been unrolled and as they appear when assembled on the roof; Figs. 3-

along the respective lines 15-15 and'16--16 of Fig. 14.

While it is old to form figures on strips of roofing material b means of various colored minerals with which the roofing strips may be coated, why other means of obtaining contrasting light effects, yet, my invention comprises not only this but a novel way of combining the contrasting light effects with the edges of the shingles themselves, so as to produce the figures sought, and also to reduce the roofing material required.

In this particular instance, I have illustrated a roll 15 which consists of two

strips

16 and 17 of shingle material, which are substantially completed and ready to be laid on the roof. The unrolled portions of the strips are flat. These strips have a serrated edge consisting of the three-sided homolo ous projections 18 and recesses 19 of strip 1 which.

are formed on the strips in any suitable manner; and they also have on their surfaces contrasting light effects which form lines of

demarcation

23 and 24. These lines, together, with the

edges

20, 21 and 22 of the strips, form substantially hexagonal figures 25, with the exception of one side 26. When the strips are laid on the roof, the rojecting edge 27 ofthe overlapping strip orms this sixth side of the hexagonal figures. As a consequence, two sides of the hexagonal figures are formed by lines of demarcation produced by the contrasting light efiects, three of the sides are formed by the edge of the same shingle strip, and the sixth side is formed by the associated .edge of the overlying strip and the complete hexagonal figures are thus clearly defined.

In Fig. 2, which illustrates the shingles assembled on a roof, the definition lines are made more definite by lines 28, and, if desired, such lines or stri es may be formed on the strips, either with or without the other contrastin light efiects.

These contrasting light efiects may be produced upon the strips in any suitable manner. In this instance, however, I prefer to produce them by means of groups of spots 30, the groups being formed so that the edges thereof will be suitable for associating with the edges of the strip, figure desired.

These spots may be formed by means of cellulose material, such as duco, which readily dries and, hence, will not stick to the other side of the strips as they are wound up into rolls. Or these spots may'be produced as raised figures by means of a bituminous min.- eral, or in any other suitable manner.

However, as stated, the contrasting light effects may be replaced by narrow stripes or lines, such as the lines 28 or the lines 35 of Fig. 9, and thus the figures desired will be formed when the shingles are assembled by means of these lines and the edges of the strips.

It will be understood that the exact length of the definition lilies, and of the straight sections formed in the edges of the strips may be varied as desired and the angles formed by these edges or lines may also vary according to the particular figure which may be desired. For instance, the lines may be made as indicated by Fig. 10, in which the lines 40 are parallel with each other and are eX- tensions of the edges 41 of the projection or lap 42 of the shingle strip. Thus, when the shingles are assembled, as indicated in Fig. 11, rectangular figures 43 will be formed, and the shape of these figures may be varied by varying the length of the lines 40 or the distance between them.

It will be noticed that, in each of these cases, the definition lines, no matter how formed, are parallel with the certain edges of the laps. In Figs. 1 and 9. the lines 38 are offset with reference to the edges 39 with which they are parallel; but, in case of Fig. 10, the lines 40 are not only parallel with but are extensions of the respective edges 41.

The shingle strips may be assembled and fastened to the roof in any suitable manner, but my invention also consists in the manner of laying or positioning the strips with reference to each other, so as to more clearly define certain edges of the figures. This consists, in part. in cutting slits 45 in the straight edges of the strips, so that lugs 46 are formed in the edges and, before the strips are assembled, these lugs 46 are turned back and downwardly onto the surface of the strips, as indicated in Fig. 2. These lugs are of such a length that, when the overlying strip has the outer edges of the projections registering with the free ends of the lugs, the strips will be properly positioned so as to form the figures desired. At the same time, the outer edge of the lug registering with the outer edge of the projection, doubles the thickness of the shingle material at this point and, thus, more clearly defines the lower edges 27 of the shingles and the upper sides of the figures to be produced, when the roof is viewed at a distance.

I also provide for locking the upper laps as indicated, to form the or projections to the lower strips of shingles when desired. This I provide for by the methods indicated by Figs. 3 to .8. One method consists in inserting in the laps 49 slits or slots 50 and inserting a tongue 51, attached to the outer end of the lug 52 of an underlying strip, through this slot 50, so as to prevent the lap 49 from bowing upwardly.

A modification of'this method of locking down the laps consists in making a slit 55 in the outer end of the lug 56 and slipping the corner 57, formed by the slit, into a slot 58 formed in the edge of the lap 59 of the overlying strip. A further modification consists in providing a tongue 62 in the outer end of the lap 61 and passing this tongue 62 down through a slot in the outer end of the lug 63 of the underlying strip.

In each of these cases, the strips of shingle material are not only easily properly positioned, but they are held very firmly in their relative positions so that there is no probability of displacement. Also, in each case, the outer edge of the lap and, thus, the

lower edge of the figures formed, is more clearly defined. Also, in each of these cases, the lap is locked down.

Figs. 12 to 14 illustrate a modification of my strip shingle. This modified strip is adapted to be laid at an angle to the eaves but, at the same time, it is adapted to form hexagonal or other figures, one edge of which is parallel to the eaves. In this case, the strips are serrated on both sides, although the serrations on the upper edge of the shingle are not a necessary part of the invention. a

The shingles, in this instance, may be cut from the sheets of shingle material as indicated in Fig. 13, and the contrasting surface portions formed thereon before or after the cutting of the sheets into shingle strips, the contrasting portions being formed in any suitable manner. Either the entire surfaces may be of contrasting appearance or merely stripes or lines of demarcation formed between surfaces, as is hereinabove described with reference to the stripes of Figs. 9 and 10.

In this case, I prefer to make the projections 70, which are to form the lap portions of the strips, with two

unequal edges

71 and 72, the edge 7 2 being adapted to be the lower edge of the figure to be formed and to be parallel with the ridge and caves of the roof. In this manner, each line of demarcation 73 formed on the surface is analagous to one of the exposed edges of the strip, while, in the case of Fig. 2, the lines of demarcation 28 are analagous to each other.

Also, in this case, the lines of demarcation which are effective in forming a figure independently of the edges of the strip are parallel with each other, while, in the former case,

they were positioned angularly. In the former case also, the two lines converge as they extend inwardly from the edge of the strip, while in this latter case, they are parallel with each other. Partly because of these variations in the two types, the former may be more properly laid longitudinally with the roof and the latter at an inclination.

The means which I provide with this latter type of strip for emphasizing the exposed edge, for positioning the shingles, and for locking down the exposed edges, consists in forming, in the'upper edge of the strips, slits and 76, so that a lug 77 is formed and turned down on the shingle as indicated in Fig. 14:. When so formed, the projecting corner 78 in the lug 77 of one shingle is positioned in the inwardly extending corner 79' of the adjacent overlying shingle, and the projection 80 of the overlying shingle is placed over the lug 77 of the underlying shin-.

gle, so that the edge 72 registers with the edge 81 of the lug 77. This completely positions the shingles with reference to each other and gives a double edge at this lower line of the figure, thus emphasizing the figure and the exposed edge.

In order to lock down the exposed corner or lap 80, any suitable means may be taken. I prefer to provide a metallic clip 85, having an angular portion 86 at one end and in the lug 77 I provide a sllt 87. The clip is positioned with the shank of the clip in the slit 87 and the portion 86 beneath the lug 77, and, when the shingles are assembled, the outer end of the clip is forced through the corner 80 of the overlying shingle and the projecting portion 88 of the clip is bent down onto the top of the corner 80, thus firmly holding the two strips of shingles together and locking the ex osed corner 80 downward.

A modi cation of this method of locking consists in the use of a nail 90, which is passed into a recess 91 in the lug 77 with the shank of the nail projecting upwardly and, when the shingles are laid, the nail is forced through the corner 80 andthe portion 92 of the nail is then bent over onto the top of the corner.

By combining these various definition lines in these various ways with the edges, to produce the figures desired, the shingle strips may be made materially wider with a given amount of lapping of the strips, as the lines take the places of the lapping edges of the ordinary manner of forming the figures, and, hence, the width of the exposed portion of the strips may be substantially. doubled, and the alternate lapping portions are thereby eliminated.
