CORRUGATED LATH BOARD.

W lliii".
SILAS M. FORD, OF ST. PAUL, MINNESOTA.
CORRUGATED LATI-L-BOAJEQD.
To all whom it may concern:
Be it known that l, SILAs M. FORD, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Corrugated Lath- Boards, of which the following is a specification.
My invention relates to improvements in corrugated lath-board of paper or other fibrous sheeting designed to be fastened to the studding or beams of buildings to serve as a foundation for plaster. For such use it is desirable to make the board rather thick in order to give it the requisite stiffness, and
\ to render its plastering face waterproof in of the insulating properties of .some suitable way. If the board is made of a single built up sheet as is now commonly the case, it is necessary to use for it a paper board which is thick enough to give it body and which is at the same time sufficiently porous and absorbent to allow the waterproofing liquid to penetrate and be partially absorbed proofed by passing it through a hot waterproofing liquid and squeezing out the surplus liquid before the sheet is corrugated or pressed to form. Paper which has the x requisite qualities for such waterproofing is is thick it expensive, and when the sheet takes up an unnecessarily large amount of the waterproofing liquid. Furthermore it will become so impregnated with the liquid that its insulating properties will be much impaired.
It is the object of this invention, among other things, to obviate the necessity of impregnating or using a thick absorbent sheet by constructing the board with a comparatively thick or stifl unwaterproofed body sheet or sheets which neednot be of absorbent material, and a thin outer or facin sheet which alone need betre'a'ted with the Specification of Letters Patent.
by it. The sheet is usually water mentioned. it have Patented Dec. 5, Jltllltb.

improved lath board, and Fig. 2 is a cross section of the same on line 22 of Fig. 1.
As shown in the drawings, the board comprises a comparatively thick, corrugated body sheet 3 to give the board the necessary stiffness and insulating properties, and a thin waterproofed outer or facing sheet 4 which overlies the sheet 3 on the plastering face of the board and is corrugated to conform to the corrugations of the sheet 3. The facing sheet 4 is preferably of absorbent material so that it can be impregnated as Well as coated with the water-proofing liquid applied to it, while the body sheet 3 which need; not be, and preferably is not, itself water-proofed need not be of absorbent material. In, practice I have found it convenient first to pass the facing sheet 4 through a bath of water-proofing liquid in the usual way and then to lay the facing sheet upon the body sheet and corrugate both sheets together, instead of one at a time. If this is done upon a machine wherein the board is fed between corrugatin rolls, the two sheets can be fed to the ro ls together, the body sheet from one reel and the water-proofed facing sheet from another reel. It may be desirable to lay the facing sheet upon the body sheet while the waterproofing is still warm and moist or sticky, sothat the two sheets will adhere together when thus assembled.
The corrugations may be of any desired shtipe and may be held to form by any suitable means such as the transverse strips 5 which are passed through the corrugations in the manner shown in my Patent N0. 1,156,866 of October 12th, 1915, but it will. be understood that][ do not limit myself to the use of any particular means of holding the corrugations to form.
Thus by the structure here shown and described I am enabled to use for the body of'the board an under sheet thick enough tog'iveit the necessary stiffness which need not be .waterproofed or of absorbent material, and! for the face of the board to which the plaster is to be applied'a thin water.-
proofed facing sheet,-thereby attaining the objects and securing the advantages above 7 spoken ofthe body sheet as a single sheet but it will be.- understood that it may comprise a pile of superposed sheets that are the equivalent of a single unitarysheet. r
I claim 1. A lath board consisting of a plurality of superposed sheets of fibrous material corrugated to form lath projections and intermediate depressions, said sheets including a body sheet to give the board the requisite stiffness and a thin waterproofed facing shvct overlying said body sheetupon theplastering face of the board.
2. A lath board consisting of a plurality of superposed sheets of fibrous material corrugated to form lath projections and intermediate depressions, said sheets including a comparatively thick, non-waterproofed body sheet to give the board the requisite stiffness and 'a thin waterproofed facing sheet overl ing said body sheet upon the plastering ace of the board.
In testimony whereof I afiix my signature in presence of two witnesses.
