EDWARD J. YETTER, 01 DENVER, COLORADO.

SEEET-ROUFING.

Specification of Application filed May 9,

and State of Colorado, have invented a new i and useful Sheet-Roofing, of which the following is a specification.

-My invention relates to a new type of flexible asphaltum shingle-appearing sheet roofing.

And the objects of my invention are:

First, to provide individual sheets or strips of asphaltum roofing material of a width corresponding to the length of an ordinary wooden shingle, their weather exposed surface being provided with raised rib members that are spaced at distancesapart corresponding to the general width of individual wooden shingles, which ribs are positioned along the length of the sheets of asphaltum thus giving to the sheets the appearance of wooden shingles.

Second, to provide long, narrow sheets or strips of asphaltum roofing material that represent shingles, which shingle representing sheets may be of any predetermined length, and which shingle representing sheets or strips are manufactured and shipped in rolls of shingle length, and which rolls are arranged to be laid in successive shingle laying and overlapping form, arranged and adapted to the same weather exposure and underlapping surfaces as is used with wooden shingles.

Third, to provide a simple and quick laying type of sheet asphaltum roofing which forms a continuous row of individually appearing shingled roofing that presents to the eye of observers when laid the appearance of a Wooden shingled roof. v

I attain these objects by the form of roof ing illustrated in the accompanying drawings in which:

Figure 1 is a perspective view of a portion of a shingle-appearing strip constructed in accordance with my invention.

Fig. 2 is a view illustrating the manner of applying the shingle strips to the roof of a house.

Fig. 3 is an edge view of two overlapplng shingle strips.-

Fig. 4 is an enlarged sectional view on the line 4-4 of Fig. 1.

Fig. 5 is an enlarged perspective view,

showing a portion of a strip having relatively wide ribs, and

Fig. 6 is a view of a fragment of a strip showing the narrow form of rib.

Similar letters of reference refer to similar parts throughout the several views. 7

Referring to the drawings, the numeral 1, designates a sheet or a strip of my flexible asphaltum shingle representing roof sheeting material, which may be especially made 1,

up in the exact lengths required for the roof it is to be laid on, or the strips may be cut from a long roll of the shingle sheeting.

Each sheet or strip 1, of my shingle representing roofing is preferably made nine inches wide and it contains at intervals of preferably eight inches apart throughout its entire length a raised rib member 2, which varies in width from about one-fourth of an inch to about three-quarters of an inch in width, the wider rib members being more easily seen on high buildings, while the narrower ribs are of ample width for low and medium height buildings. These raised rib members extend from the lower edge 3, of the shingle sheeting across its width for a distance of preferably four inches, which distance is the preferred width of the weather exposed surface 4:, of the strip of shingle representing roof sheeting.

As my continuous shingle representing strips of roofing are nine inches wide and as four inches of it is exposed to the weather, the remaining five inches represents the underlapping portion 5, of the shingle strip, and of this five inches about one inch forms an underlapping edge 6, which lies against the roof boards 7, and is overlapped five inches by the second shingle strip 1 above it, as shown at 8, in Fig. 2, and is overlapped about one inch by the lower end 9, of the third shingle strip 1 above it, andmy continuous shingle representing strips of flexible asphaltum are laid in this progressive overlapping order from the lower edge of a roof to its upper edge which arrangement forms a three-ply thickness or three layers of the shingle representing roofing strips along the upper edge portion 12, of the weather exposed part of each shingle member and along each longitudinally extending layer of the roof sheeting strips across the roof of a building.

The upper underlapping five inch portion in i 5, of each shinglerepresenting strips 1, of roof sheeting, 18 provided with'raised rib members 2, the same as the lower four nch weather exposed portion 4, and the raised ribs 2 of the underlapping portion 5, of the a long shingle strip 1, are all also positioned at eight inches apart, by which is meant that they'are eight inches apart from center to center of the ribs, which is also the distance apart of the lower ribs 2, on the lower weather exposed portion 4, of the sh1ngle* strips. These raised members are designed to represent to the eye the cracksior narrow spaces that occur between wooden shingles when laid, and also that become more pronounced? through shrinkage of the wooden shin les after they are laid.

y invention contemplates any way of representing on the surface of the shingle strips 1, of my asphaltum roofing material, such form and shape and character of raised rib members spaced at what is considered standard' width of wood shingles that will represent to the eye of an observer from the street, a roof that has been shingled with individual shingles, and I have represented both a wide rib 2, in Fig. 5, and a narrow rib 2 in Fig 6.

My inventlon contemplates shingle representing ribs of any*width, and they are formed by subjecting the strips of asphaltum to a rolling pressure, which is applied by feeding the strips through suitably formed rolls which forces the ribs outwardly from the weather exposed side of these shingle wide strips into a" narrow rib-like portion of j the asphaltum, which pressed out rib-members project preferably about an eighth of an inch above the surface of all of the rest of the width and length of these shingle strips of asphaltum roofing material, which is rolled out fiat and smooth. and of even thickness throughout their entire length and width except where their raised ribs are formed.

In pressing out and thus projecting outwardly these ribs from the surface of the shingle forming strips 1, a recess 10, of corresponding depth and width is formed in the under side surfaces of each rib exactly opposite to them as these ribs are formed by a swaging pressure movement that forces a raised rib shaped member ofthe shingle strip bodily at right angles to the underside surface 11, of the shingle sheets, which forms the recess and at the same time forms the raised or projecting rib 2, on the upper and they are positioned centrall between the ribs 2, of the weather exposed ower art of the shingle strips, and they extend rom the upper edge 12, of the shingle strips, down to even with the u per ends of the lower ribs 2, which is de ned by a dotted line 13, and these upper shallow depth ribs have been especially desi nod to act as guide ribs to enable the shing e laying workman to plainly see that each shingle strip must be laid so that these shallower ribs will stand centrally between the ribs 2, on the same strip and in line with the ribs 2 on the shingle below; that'is, that they will la and extend upward from the center 0 the eight inch space between the lower ribs in centrally positioned offset and alternate order of arrangement; and in'laying the shingle strips the lower edges of each stri laid is placed with its lower edge throug out its length 5 across the length of the'roll close up againstthe upper ends of the lower ribs 2, which would be along the dotted line 13, as the upper ends of the ribs 2, form a guide line across the roof that the lower edge of each shingle strip that is to be laid on the one already laid is to be placed against, and

when this is done the recesses in the under side of the lower portion of each shingle sheet as it is laid fits down over the shallower ribs 2 of the upper part 5, of the shingle strip that has been already laid on the roof. I

The operation of laying my improved long, thin and flexible strips of shingle rep- 100 resenting flexible asphaltum roofing material on pitch or inclined roofs is as follows and is as illustrated in Fig. 2:

A strip of the shingle representing roofmg asphaltum is laid either fully across a 105 roof lengthwise of it or as far across as desired at its lower or eaves edge, and is nailed to the roof boards;'but the lower edge of this first shingle strip is bent down over the eaves board 3 and is extended far 110 enough below its lower edge to form a water drlpplng edge, and this overlapping edge ofthls lower or first strip is then nailed to the eaves strip 3. A second sheet is then laid fiatwise also alongthe length of the 115 roof parallel to the first strip and overlapplng the upper edge portion of it five inches;

the workman adjusting the lower edge of the second to lay against the upper edges of the raised ribs 2, of the first shingle strip 2 laterally sothat the ribs recesses on its under side will fit over the shallow ribs on the upper'portion of the first and lower strip that has been nailed to the roof, which allows the fiat under side surface of the upper 1 5 part of the second shingle strip to lie flat down against the lower shingle strip below it, and as it is soft and flexible it is easily pressed down perfectly fiat and smooth over the upper part of the strip underneath by the workman who then nails ittightly to the shingle strip below it. A third shingle stri is then laid to overlap the upper part 0 the second shingle strip and is nailed to it and to the roof, as shown and the lower edge portion of the thir shingle strip can be nailed to the second shingle strip and also the one inch wide upper edge portion 6,- of the first shingle laid on-the roof which projects up under about an inch of the lower edge of the third shingle strip, consequentlyithere are three thicknesses of the shingle strips along the whole length of the roof at this triple overlapping portion of them. The shingle 4 strips are then laid in successive order to the ridge of the roof across its width or height.

My invention provides a thoroughly practical, durable and quickly and cheaply laid shingle representing roofing of an asphaltum composition that has been in constant use for roofings for buildings of all kinds for a good many years, a practical application of which was invented and patented by me in Patent No. 1,148,647, issued August a, 1915.

Having described my inyention what I claim as new and desire to secure by Letters Patent is:

shingles and provided with raised rib mem-' here on its weather exposed side positioned in offset centrally spaced order in two. rows along the length of said strip and arranged to define the outlines :of separately laid shlngles having an exposed surface of standard width; the lower row of saidribs being adapted to be exposed to the weather with the lower portion of said strip and the upper row being formed to act as a guide in placing another shingle strip over the lower one in shingle laying order.
