CHARLES S.- BIRD, OF WALPOLE, MASSACHUSETTS.
Application filed August 9, 1911.
' lValpole, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Building Material, of which the following is a specification, reference being had to the accompanying drawings, forming part thereof.
This invention has reference to improvements in building material and particularly to improvements in building paper adapted for use as an exterior covering for roofs.
The object of the invention is to so construct building or roofing material com rising a flexible base, preferably formed 0 paper, and having a layer of asphaltic material of substantial thickness and provided with a surface coating of powdered soapstone, sand or other comparatively small elements adapted to protect the asphaltic material from the action of the weather that said surface coating shall be divided, in appearance; into blocks of suitable size and shape without destroying the protective qualities of said surface coating.
Other objects of the invention will appear from the following description.
The invention consists 1n building material comprising a sheet or strip of paper furnished with a layer of asphaltic material having on its surface areas of weather resisting mineral. elements divided by surface areasof the.asphaltic material, said areas of asphaltic material. being preferably arranged as stripes or lines. f
The invention also consists in such other novel features of construction and the relation of parts as shall hereinafter be more fully described and 'pointed out in the claim.
Figure 1, represents a plan View of a iece of building material illustrati thls invention. Fig. 2, represents an en arged sectional view taken on line 22 Fig. 1.
Fig. 3, represents a sectional .view similar to.
Fig. 2 illustrating a modified form of the invention.
Similar numerals of reference designate corresponding parts throughout.
Building material of this general nature heretofore has been constructed-by taking a sheet or strip ,of paper, supplying sald paper with a comparatively thick water reslstlng or water-proofing layer containing a comparatively large proportion of asphaltic ma- Specification of Letters Patent.

terial and applying to the surface of said water resisting coatinga comparatively thin.
coating or layer of small particles of powdered soapstone, sand or similar, preferably mineral, elements which adhere to the surface of the water resisting coating andtend to a considerable degree to protect the water resisting layer from the action of the weather. This protective coating extends in an unbroken area over the surface of the material and presents a monotonous appearance which militates against the extended use of the material in conspicuous locations where the use of such material is otherwise desirable.
In carrying this invention into practice it has been my desire to so construct building material and particularly roofing paper I of the same general nature as that'heretofore used but having its. constituent mechanical elements so combined and related that the protective surface coating of powdered soapstone or. other small particles is divided into ornamental area-s by other areas, lines or stripes in such manner that the same constituent elements are preferably present in all of said areas, lines or stripes and, in its preferred form, that the said protective coating shall be continuous as regards its protective qualities.
In construct-ing this material I preferably take a sheet or strip 5 of paper or other suitable material adapted to be used as abase or backing and to such base 5 I supply the water resisting layer 6 preferably containing tar of some kind or asphaltic material, and to the surface of the layer 6 I supply powdered soapstone, sand or other mineral particles which adhere to the surface of the layer 6 and form the protective coating? of a color preferably in contact to that of the layer 6. I now take this ma-' terial and by heat orpressure or by combined heat and pressure applied to the surface of the coating 7 in a predetermined design I cause the soapstone or similar particles in the lines or areas 8, 8 of such design to become so embedded in the material of the layer 6 that the greater portions of tional view of a piece of building paper 5 having the layer 6 of asphaltic water resisting material to the surface of which powdered soapstone or sand is applied as at 9, 9 leaving the surface of the material 6 exposed at other points to form a design but this modified construction is not as desirable as that shown in Fig. 2 for the reason that the protective coating of mineral particles is not continuous.
WVhile Ihave attempted to show in the drawings the approximate relations of the different elements of the invention, I do not intend the'reby'to limit myself to the use of particles of, mineral or other material of any particular size for the coating 7. It is also evident that the shape of said particles may be different from that shown and that such shapes and sizes cannot be readily shown in a drawing.
In my preferred form I do not Wish to limit myself to any particular method of production as, for instance, the embedment of those portions of the particles of the coating 7, forming the design 8, into the layer 6 may result from the application thereto of a solvent for the material of sald layer 6 whereby said layer is, at points, so softened that said particles of the protective coating will sink into the surface of layer 6. Having thus described my inventlon, I claim as new and desire to secure by Letters Patent I I Building and roofing material comprising a sheet 'of paper furnished with 'an asphaltic coating having a continuous layer of soapstone particles, certain areas or lines of said particles being embedded in said asphaltic material thereby exposing the asphaltlc material and producing areas or lines of contrastlng color.
