Beit known that I, Mennnltil. FnnnnnnxsEN, acitizen. of the United. States, and a resident of flan Francisco, county of San Francisco, State of California, have invented a new and useful Sheathing Board, of which the following is a specification.

This invention relates to sheathing boards and has for, its primary object the pro vision of anarticle of this character which simple of construction; inexpensive of manufacture; lie-ht in weight; strong and durable, and which, through a novel arrangement of parts, permits of its use in building construction so that the customary costly and objectionable metal lathing can be dispensed with, and wherein said parts combine to constitute a key or retaining surface for a plastic material such as stucco.

A further object of the invention is to provide adevice of this character which shall be of such formation that it will not readily warp or bulge and which will'uniformly adapt itself to a plastic composition a smooth wall surface of uniform thickness may be set up.

A still further object of the invention is to provide sheathing of this character wherein the sections thereof when set up will provide waterproof oints between the respective sections thereof. Further objects and advantages of my invention will appear as the specification proceeds. p

'In the drawings, Figure 1 is a perspective 'view of the sheathing board, and Figure is a vertical section through several sections of the board showing a concrete or plastic facing applied thereto.

y invention, therefore, comprises certain new features of construction and arrangement and combination of elements hereinafter set forth and pointed out in the claims annexed hereto.

In carrying the invention into practice, use is made of an inner sheet of material (10) such as paper board, fibre or wood veneer, the same having a plurality of slats (6) secured thereto in any suitable well-- known manner such as by an adhesive. These slats are arranged side by side with their side edges abutting each other. In the present illustration of the invention it is seen that the joints between the aforesaid slats (6) extend downward at an acute angle to the upper edge of the sheet (10) v ferred to,

and that the grain of the wood runs in the length of the slats.

Secured to the outer face of the plane surface formed by the abutting slats (6) are longitudinal slats (7 spaced apart to form continuous key ways (8). These slats (7) are preferably formed of material of the same specie as the sheet (10) and it will be noticed that the grain of the slats runs longitudinal therewith and that the slats are arranged at right angles to the joints of the interposed slats In this man ner the sheet (10) and the slats (7) are firmly bound to the said intermediate slats and the board face throughout, and incident to the man nor of crossing the slats (7) with respect to the slats (6) the board is held against undue warping or bulging out.

In manufacturing the U take two rectangular sheets of material. the same as sheet '(10) herein specifically reand arrange them respectively at the opposite sides of the abutting slats (6), binding the parts together firmly by an adhesive or the equivalent thereof. I then subject the outer one of these sheets to the action of a trimming and gouging mechanism so as to produce the slat formation hereinbefore mentioned, the same constituting the key surface on the outside of the sheathing. In this gouging and trimming operation the grooves (8) are formed and the upper and lower edges of the finished board are mitred as shown at- (9) so that when several of these boards are placed one on top of another in superposed relation the lower mitred edge of one board overlaps the upper mitred edge of an adjacent lower board. In this manner water that may collect in the wall surface is free to flow downwardly to the ground line instead of passing inward through the joints between the sections of the sheathing.

By placing the slats (7) apart as described, I am able to apply a plastic com position (10) to the outer surface of the sheathing and as it is troweled, parts of the plaster are taken into the grooves (8) and constitute-effective keys to hold the plaster in set position. The construction of the invention is such that the board may be nailed to the customary studding of a building frame.

I claim:

board I preferablv 1. Sheathing board comprising two thin strips of material and a plurality of slats arranged between said strips and secure thereto the said slats having their side edges abutting; each other, one of said strips being divided to provide a number of spaced apart slats extending at right angles to the joints between said interposed slats.

2. Sheathing board cpinprising an inner strip of material, a plurality of slats secured to said strip and arranged With their edges abutting each other, and a plurality of slats secured to the first said slats and traversing the joints thereof, the second said slats arranged with their longitudinal edges iormedto define key Ways for a plastic composition.
