noorme ELEMENT.
Specification of'Letters Patent. Patented May 1920.
Application filed October 17, 1918. Serial No. 258,523.
To all coho 1n it may concern:
Be it known that I, CHESTER E. RAHR, a citlzen of the United States, residing at Brookline, in the county of Norfolk and State of Massachusetts, have invented new and useful Improvements in Roofing Elements, of which the following is a specification. A
This invention has relation to roofing materials and has for its object to provide certain improvements therein.
, The invention consists of a roofing element; that is, a sheet or shingle in which the asphalt-saturated fibrous foundation has on its upper and lower sides or faces coated and uncoated parallel zones, the coated zone of one face overlying or underlying, as the case may be, the uncoated zone of the other face. Each coated zone is less than one-half the width of the element so as to provide a middle zone which is uncoated on each face..-
Preferably eachcoating consists of a layer of asphalt,.pitch or like material of relatively high melting point, in which is em- 25,
ent colors or shades may be employed, so
that, reversing-the sheet, one or the other color may be exposed in laying the roof covering. In lieu, :however, of forming both surface layers of grit, one of them. may
consist of sheet asbestos, which, like crushed slate, serves as a fire-retardant, or some other sheet material.
For many purposes it is desired that at least a portion of each sheet shall be left Figure 1, represents a portion of a sheet of roofing embodying the invention, said sheet being illustrated in conventional .form. Fig. 2 illustrates a shingle which embodies the invention.
I Fig. 3 is a conventional view illustrating how the sheet shown in Fi 1 may be wound into a roll of minimum diameter.
section.
The body of the roofing element, whether f it be a sheet or a shingle, consists of felt, preferably' rag felt or equivalent fibrous mat'eriahwhich is saturated with a relatively low-melting-point pitch 'or asphaltum, or other equivalent waterproofing compound, such .as used in themanufacture of .com-. mercial roofing-felts.
On the drawing, this fibrous foundation is indicated conventionally at a. This saturatin compound is applied to the foundation 5y drawing a sheet of felt through a saturating tank inwhich the compound is maintained at the desired degree of fluidity by the application of heat, the excess orsurplus compound being expressed from the sheet by squeeze rolls, thereby leaving the face of the sheet rough with the surface fibers more or less exposed. Upon the lower portion of the'upper face or side of the sheet, there is applied by any suitable instrumentality, such as a coating roller, a layer b of higher-melting-point pitch or asphalt,--preferably blown asphalt having a melting point s ufii ciently high so that the asphalt will not be affected by solar heat. This layer 5 covers a zone of the sheet between the edges thereof, which zone is less 1 than one-half of the width of. the sheet. A
similar layer c of pitch or asphalt is applied to the under side or face of the sheet, but is located below or under the uncoated zone 03 ofthe top face.
width of the sheet" a, sothat, between the inner edge e of the upper coating 5 andthe inner edge i of the lower layer or coating This coating 0 is. likewise in width less than one-half of the 0 there is a zone 9 of the sheet parallel with f and intermediate the upper and lower edges thereof which is nncoated on both faces.
While these coatings b and c are soft and 7 plastic, I embed therein surface layers of crushed mineral, preferably crushed slate, as indicated at h and 73 respectively. By forming these two layers It and i of slate of different or contrasting colors or tintsit. is
possible for the user to solay the sheetor element as to expose the layer of the desired color, or to lay the sheets to form bands of. different colors.
. In some mstances, instead of a fire-resistant layer of crushed mineral z, I may substitute a sheet of asbestos in lieu thereof, this asbestos being locked to the foundation-a by the layer of asphaltum. Or, if desired, 1 J
j asphalt-impregnated foundation, one side may substitute a sheet of heavy canvas or burlap or. other fabric which will increase the strength of the roofing when laid.
In Fig. 2, I have shown a roofing shingle, having the same construction as that described except that naturally it is of the proper dimensions. 1
Assuming thatthe sheet in Fig. 1, between its upper and lower edges, is thirty-two inches in width, each coated zone is preferably fifteen inches in width, leaving an intermediate zone of two inches on which there is no coating on either face. These same relative proportions are preserved prefeiably in a shingle, which of course is of smaller dimensions, say nine by sixteen inches. By having the uncoated zone 9, it is possible to coil the sheet into a roll of minimum diameter, the uncoated zone of each convolution bending so as to permit the convolutions to assume the shape show'n in Fig. 3. The shingles may be packed in a compact package, by reason of the zone 9 to accomplish a practically like result.
Having thus explained the nature. of my said invention, what I claim is I. A roofing element comprising a fibrous asphalt-impregnated foundation having its opposite faces "coated with asphaltic material in zones, parallel with the top and bottom edges thereof, with fire-resistant material, the coated zone of one face being opposite the uncoated zone of the other face.
2. A roofing element comprising a fibrous asphalt-impregnated foundation having an intermediate zone which is uncoated on either face thereof, and having upper and lower zones of which one is coated with a surfacing material on one face and the other is coated on the opposlte face.
3. A roofing element comprising a fibrous of said foundation being provided with an asphaltic coating which covers only the lower portion thereofand' the other side-be ing provided with a coatingwhich covers only the upper portion, said coatings being surfaced with mineral material.
at. A roofing element comprising a fibrous.
asphalt-impregnated foundation, one side of said foundation being provided with a coating which covers only the lower portion thereof and the other side being provided with a coating which covers only the upper portion, each of said coatings being fire-retardant.
5. A roofing element comprising a fibrous asphalt-impregnated foundation, one side.
said foundation being provided with a coating which covers only the lower portion thereof and the other side being provided with'a coating which covers only the upper portion, each of said coatings comprising a layer of asphalt and a surface layer of crushed mineral embedded therein, the said minerals being different in color or tint.
In testimony whereof I have afiixed my signature.
CHESTER EQRAHR.
