L. LEWIS SAGENDORPH, OF CINCINNATI, OHIO.
SPECIFICATION forming part of Letters Patent No. 252,524, dated January 17, 1882.
Application filed November 26, 1881. (No specimens.)
To all whom it may concern:
Be it known that I, L. LEWIS SAGENDORPH, acitizen of the United States, residing at Gincinnati, in the county of Hamilton and State of Ohio, have invented certainnew and useful- Improvements in Roofing-Material, of which the following is a specification.
The object of my invention is to furnish a material for covering the exteriors of roofs of buildings, of decks of vessels, and other like structures which are exposed to the weather, and which are required to be made both fire and water proof.
In carrying out my invention I first prepare a liquid mixture having substantially the characteristics of a metallic paint, which may consist of any suitable metallic substance, prefer- I ably an oxide of iron, which is reduced to a finely-divided state and incorporated with a suitable vehicle, such as linseed or other oil. I place a sufficient quantity of this mixturein a suitable vessel. I then take a piece of fibrous or textile material, preferably duck or canvas, of any required length, and cause the same to pass continuously through the said liquid mix ture, by which operation the fibrous material becomes partially or wholly saturated with the mixture, a considerable quantity of which also adheres to its surfaces. After the fabric has been thus saturated and coated it is immediately made to pass slowly between steel or iron rollers in a manner well understood, and is thereby subjected to heavy pressure, by which operation the mixture is forced into all the meshes and intersticesof the fabric, while the surplus adherent material is at the same time removed. tion the fabric is exposed to the atmosphere and allowed to dry and become hard. I then pass the fabric a second time through the same or a similar mixture and through the compressin g-rollers in the same manner as before, whereby its surface receives an additional coating of After the completion of this operasurface of the fabric is in an adhesive condition, hydraulic cement of-any suitable kind in a dry pulve'rulent condition is applied on one side only of the fabric. The adhesive character of the mixture will cause the fabric to retain upon its surface a thick coating of the powdered cement, and the whole is then allowed to dry, after which it is ready for use.
It may be sufficient for some purposes topass the fabric between the com pressin g-rollers but once, and immediately thereafter to apply the artificial-stone or cement facing; but I consider it preferable to subject the material a second time to the process of saturation and coating with the mixture before applying the facing, as hereinbefore set forth.
The object in applying the powdered cement is for the purpose of preserving and protecting the metallic paint, and also to prevent the completed fabric from becoming adherent when put up in rolls for shipment. When employed as a rooting material the cement protects the metallic substance from the injurious effects of moisture and the rays of the sun, inasmuch as when moisture comes for the first timeiu contact with the cement surface it immediately converts it into an artificial stone, which renders the roof absolutely fire-proof. When used for covering the deck of a steamboat or other vessel the surface may be walked upon without injury to the fabric which forms its basis. I prefer to use for forming the artificial-stone facing some one of the well-known hydraulic cements-such, for example, as that commercially known as Neufchatel stone or Portland cement.
The flexible fire and water proof fabric thus prepared may be conveniently packed in rolls for shipment, and may be applied to the roofs and other exterior portions of buildings, the decks of vessels, and other like purposes by securing sheets or pieces of convenient size thereupon by means of nails, cleats, or other well-known means. When thus employed it is unaffected by exposure to the weather, water, or fire, and hence it forms a comparatively cheap and at the same time almost indestructible protection.
I claim as my invention- 0 i The improved roofing material hereinbefore In testimony whereof I have hereunto subdescribed, consisting of a fibrous or textile fabscribed my name this 22d day of November, ric having its interstices filled under pressure A. D. 1881.
