BUILDING MATERIAL.

' .Specification of Letters Patent.

Patented Nov.l 3,1914.' i

Application filed March 16, 1914. Serial No. 825,020.,

To all whom 'it may concern.:

Beit known that a citizen of the United States, residing at Youngstown, in the county of Mahoning and State 'ofjOhio, havev invented certain new and usefulmprovements in Building 'Material, of which the following is a specification.

This invention relates to a novel and practical building material for use -in building constructioiifi though available chieiiy for 'latliing, andlg'tlie object of the invention is to provide 'a5-material of this nature which shall be'economical in production, easily an cheaply applied, and readily transported.l

Accordingly, a general object of the iii- =vention is to provide-a new and practical article which may be employed as a solistitute for wooden and metal lathing and which can be plastered with a minimum while at the same time possessing the desir: ble quality of not swelling and warping after the lmanner of wood latli, nor rusting after the manner of nietallic lath.

With these and other objects in view which will be apparent' to with this art, -the invention consists in the novel construction, combination, and aru rangement of parts hereinafter more fully described, illustrated, and claimed.

' For thel purposes of illustration, a preferlable embodiment of 'the invention is shown in the accompanying drawings, in which- Figure l is a plan view of a sheet of building material constructed in accordance with the present invention.

Fig. 2 is fragmentary plan view of a piece of the improved building material illustrating the superficial characteristic thereof prior to its treatment with an artificial stone or equivalent composition which covers and protects the edges of the paper facing sheets. Fig. 3 is an enlarged sectional view on the line 3-3 of Fig. 1,' exaggeratingthe thickness of the sheets and of the coatings. Fig. 4 is a cross sectional view of the new product on the line 4-4 of Fig. 1. Fig. 5 is a sectional view illustrating a section of the new material fastened to urring or studding and showing a plaster surface applied thereto and interlocked 'within and behind the key openings which are disposed adjacent the longitudinal plane of the ridges of the corrugations.

I, HERBERT E. WHITE,v

' rugations may be of various shape,

those fam iliai- Like reference characters designate` corresponding parts in the several igures'of the. drawings. A 'A 'f-i-:

A. distinguishing characteristic of the present invention palper body so constructed Aand reinforcedes to have the requisite strength and stiiness toA rovide an economical and durable orm Y egt uilding material possessing special utility as a substitute for-wooden andA metal laths. Accordingly, the' new material claimed herein primarily'includes a sheet' of fibrous corrugated l body, material A having a. multiplicity of corrugations.

These corsize and extent.- They may be uniform or non-uni form, and may beproduced in any suitable-n is that of providing amanner, but for the purposes of illustration, i

the forni of the invention shown inithe drawings has corrugations of a uniform character and extending throughout tlieenv tire area of the sheet, these corrugations consisting of a regular series of alternating ridges a and intervening valleys b.

In addition to the stiiiening and. reinforcing effect produced by the corrugated formation of the body sheet A, the latter has combined therewith the stiiening facing sheets B-B arranged upon opposite'sides thereof and coextensive in Varea therewith. Thesefacing sheets are of paper or equivalcnribrous material and are gluedor other wise suitably fastened to the bodysheet so that they will have a fastened union with the ridges a: ofthe corrugations, and thus become a permanent part of the body material and contribute materially to the stiffness reinforcement, and durability of the product.

A novel feature of the present invention resides in the' revision of practical and effective means or keying the laster or other cementitious substance to the paper lath. This is accomplished by breaking up the facing sheet B-B into a number of key openings C arranged in longitudinal rows with p the key openings in eachrow disposed adj acent to and exposing sections of one of the ridges a oi the corrugated sheet A. That is to say, there are a series of longitudinal rows of key openings C, and the key openr ings of adjacent rows in ca ch. sheet B are disposed iii alternating or staggered relation. The key openings in one sheet..B -are preferably in dierent longitudinal planes 5 particularly,byeferenceto Fig. l of the drawings, that each longitudinal row of' the keyr openings C is intersected by one of the longitudinal ridges.A a of the corrugations,

thereby exposing several sections' of this y ridge respectively at .the different key open ings in the same row `of the latter, andl With.'-

the said key openings disposed uponfbth sides of the ridge so' as to be in communie-.1- tiofniyithv theyalleys upon both sides of thesaid ridge. 'It is by reason of this constructionv that each keying unit consistingA of' a:l section o-ffthe ridge a and openings hp'on bot-hv'V sides thereof, providesv means whereby. the,v plaster or other cementitious substance fillsthrugh said. openings over the corrugaition ridge a, into the adjacent `4`i,-'alleys 2 1, and behind the. )rejecting edges c, zircifthe'leyf openings, as shown in F ig. 5 of tlie'edi'aWings.@This secures a most effectual keyinggof the `plaster to the paper lath, and byreason ,ofthe gnat number of keying ilnitsfor'zkeying points, of a similar characa"ter', an,eftectiyeanduniform tie is provided betne'entheplaster and the paper lath.

preferable .in carrying out the invention to, treat Athe paper body, yeonsist-ingo fthe corrugated sheet. A and the facing sheets .'B-'B to-.a1eonipoundlhat will add to the stiifnesandstrength of the article, as well as in'ipa'rt..waterproofing and ire-iesistineb.

characteristics thereto. The corrugated formation ofthe sheet A and the many 'openings-Gin both facing sheets thereof render the product specially' adaptable to a bath of such compound-Which is thus permitted to entenall ofthe corrugations, as well as to goat bothz the .outer and inner faces ot' the facing sheets-and to cover all edges of mate rial, ,particularly the edges of the key openings rl`his .prevents moisture from entering the fibrous sheets at the edges, with the result of startingdeteriorationthereof, particularly swelling and warping.

An articial stone compound may be employed for this purpose, an example of which Will be a solution of silicate of soda, infusorial earth, and oxid of zine, ora waterproong Aand hre-resisting compound that could be.

lutilized with good result is one consisting of t a'fmixture of silicate of soda and asphaltum or oxid of iron. The manner in which the ,stiffening and protective compound provides it Well deiined superficial coating throughout the product is shown in Fig. 3 of the drawings, the compound 4coating being designated by the reference letter ai.
