This invention relates to the production of a reinforced fibrous composition sheet, suitable 4'for rooingsiding and similar purposes and has for its object the economicalq production of' sheets possessing the very desirable properties of this' fibrous composiresistance to the elements coupled with stiffness and strength necessary 4to permit-its use'insheets for siding and roofing in much the same way that iron .is now used. Metal will generally, but not necessarily, be used'as the reinforcing material. The product is much cheaper than plain orgalvanized sheet iron and at the Sametime possesses greater resistance to action of the elements than does the plain sheet iron, and in some cases has greater wearing properties than even the galvanized sheet iron.`A I

Inthe patent of James C. Woodley,.No. 1,156,122, dated October 12, 1915, fory fibrous composition and process of manufacture is manufacture of the described the composition" and method of /brous composition which is preferably used in connection with .suitable reinforcing. This reinforcing may take the form of metal wire mesh or of eX- panded metal, or of thin perforated. sheets of metal, the word reticulatedy being used to include all these and equivalent constructions; The fibrous composition serves to protect from the elements the metal base, which is ordinarily ungalvanized, and atthesame time in the case of wire mesh o r perf forated or expanded metal, servestolill the web, making a finished. sheet having-the required stiffness andother properties for the purposes in'hand. The product may be supsheets or in many c ases 1t 1s plied in fiat preferable to supply them-corrugated, 1n

the same way that sheet iron is corrugated.

These sheets may be of anydesired thick ness, width and length.v

It has been previously proposed to make felt roofing in corrugatedsheets composed o f two 'or more sheets of felt and an lntermediate interstitial web of metal but such prodsheet RATION or wns'r ,menne- Letters atent. Patented 25, 1915. serial Nq. 10,392'.

The preferred method material' fibrous nature', so'that rf'f the fibers are distributed substantially homos the binder and are and in some of' forming` the product is to introduce awire mesh between a pairof compression rolls and at thefsame time place' .some of the above-described fibrous composition on each side of thewire.

mesh in such a manner that as the rolls re`- volve they draw forward the wire mesh and at the same. time the fibrous'compo's each face thereof and cause the w to be .embedded in the fibrous o,

some cases it may be advantageous'to per- ...mesh

form this operation with two setsof such rolls vas the product from 4the first set may not give a perfectly -uniforxsnsheet and we may then lead this imperfectly to a seco-nd set where a further supply of the fibrous composition is introduce and perfecte-the sheet as delivered. .Or the lcomposition may first be` passed between rolls formed sheet or in any other desired way formed "into i sheets; lwhich sheets','with the wire mesh bevgeneous sheet in which the, wire mesh is embedded.

The sheet coming from the compressionV rolls is cutfto the desired length and we may liso the

secure in this way sheets say eight feet or ten feet long and perhaps thirty-six inches wide. These sheets are then passed between corru'gating` rolls of the type usually em ployed with roofing sheets and corrugated to the desired pitch.

We may, 1f desired, omit the corrugating process and ordinarily would do this if we used expanded metal for the reinforcing. Thev corrugating serves in general to increase the stiffness and strength of the product.

The accompanying drawings illustrate the processand product in connection with suitable apparatus. A

Figure 1 is a cross-section and Fig. 2 a side elevation showing the making of the product from previously unformed masses of roong composition; Fig. 3 is a cross-section showing the making of the product from masses of the composition* whichv have been previously converted into' the form of sheets; Fig. 4 is a schematic view illustrating product in section on an enlarged scale. The rolls A `are 'the compression rolls in the directions indicated by the arrows. The-rolls B are arranged in advance of the compression rolls and serve to straighten the wire screen C which is passed between them and down into the space between the forming rolls A. The wire screen is supplied on a roll D whence it is carried down between the rolls A and B, as shown. The

y fibrous composition is supplied in unformed screen, Y tically masses E at such temperature as to be suitably plastic. Such a mass of fibrous composition is applied toboth sides of the wire screen C and is caught and carried down by the rolls A and compressed between them, carrying the wire screen along so that the nlatter is embedded in -the product F. The fibers inthe composition, while adherent to each other by reason of the' bituminous binder, are not permanently attached 4to each other and are thus free to be forced into the meshes of' the Wire screen in the manner indicated in. Fig. 4, so that the masses E do not remain separate on' opposite faces of the but are united so as to form praca single layer or sheet of fibrous cornposltion coating both faces of the screen which is embedded therein and to a degree interlaced. with the fibers. y a

For greater convenience in handling the fibrous composition and for more accurately determining the quantities thereof on oppo; site sides of the sheet such composition may vforming .E' ,p a temperature as to be fibers into the be first formed into sheets E (Fig. 3) which are carried from rolls G and over idlers H to the space between the compression and rolls A; the wire screen being handled the same as in Fig. 1. The sheets must be of such composition and at such quite plastic and to permit the compression and forcing of the meshes of the reinforce as above described.

Fig. l shows the sheet F passed through a second set of compressing and forming rolls A with additional quantities or masses E of fibrous compositionvlapplied to the sides as desired to perfect the product in the matter of thickness of the composition on opposite sides, and to additionally compresst if that be desired.

The fibrous composition may be of the i natural color or be artificially colored, or that supplied to one face only may be artificially colored or the composition applied to one face may be of a different grade from that supplied to theother. Similarly the composition supplied to the second set of rolls A may be different from that supplied to the rst set and may be artificially colored on one or on both sides so as to produce a product having a veneer of colored material. This method of coloring the sheets is described in full and claimed in an application of mine pending concurrently herewith.

Though I have described with great par` ticularity of detail certainspecific embodiments of my invention, yet it is not to' be understood therefrom that the invention is restricted to the particular embodiments disclosed. Various modifications thereof may be made by those skilled in the art without departure from the invention.

What I claim is- 1. A reinforced fibrous composition sheet comprising a reticulated reinforce embedded in a body of brous composition consisting of a bituminous binding material and elementary fibers distributed substantially uniformly and homogeneously throughout the lmass and separately and thoroughly coated with the binder and interlaced or felted together, the proportions being such as to render the composition'non-liquefiable by heat, said fibrous composition passing through the meshes of the reinforce.

2. A reinforced 4fibrous composition sheet comprising a reticulated reinforce embedded in a body of brous composition comprising fibers of paper coated with bituminous material andf adherent but not permanently attached to one another, said fibrous composition passing through the meshesof the reinforce.

5. A reinforced-:fibrouscomposition sheet-D 'herentbut not permanently attached tuo one another, the proportions being'such as to render the composition non-liqueable .by
