SIDE AND CORNER FOR BUILDINGS.

Application filed May 23, 1918. Serial No. 236,162.

To all whom iii-may concern:

' Be it known that I, JopN K. SHAV,R

citizen of the United States, residing, at.

Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Side Valls and Corners for Buildings; and I do hereby V declare the following to be a full, clear,'and exact description of the invention, such as will enable others skilled in the art to which -Referring to the accompanying drawingsforming a part of this specification in which like numerals designate like parts in all'the vie\vs Figure l is an elevational view of a corner of the building treated in accordance with this invention;

Fig. 2 is a sectional View on the line 22 of Fig. 3, looking in the direction of the arrows;

Fig. 3 is a sectional view on the line 33 5 of Fig. 2, ldoking in the direction of the .arrows; and- Fig. 4 is an elevational View of the metal corner clip employed in this invention.

1, 2 and '3 indicate the upright timbers constituting the main corner supports of a building, 4 and 5 indicate the usual wooden side wall material employed in such buildings and 6 and 7 indicate sla'bs or boards made of.the material well known on the market as' insulite. This .insulite material is a paper board material ma-de of fibers obtained from wood but it differs from the ordinary paper board in that it is exceed- .eingly light and is possessed of an unusual high heat insulating Quality. That is to say, it resembles cork in many of its physical qualities it having a specific gravity of say not more than .3 or .4 and it often-has a specific gravity as low as .2 or lower.

It is made of at least three different classes of fibers. The one class isso coarse that they really constitute slivers in that they are say often one eighth of an inch wide, and one half to one inch in length. The second class of fibers are more or less string like in that they are say from one thirty second of an inch to one sixty fourth of an'inch wide, and are from one half to one inch, or two inches long.

Thethird class of fibers are more or less hairlike inthat they are from say one hundredth to one two hundredth of an inchin diameter and are/say from one half inch or less in length.

. In addition to these various classes of fibers, the mass is mixed with a considerable quantity of ordinary sulfite fibers employed in paper making. The result of felting together'into a homogeneous mass fibers having such great variations in their coarseness is to make a body having great porosity. high heat insulatingqualities, and'gone Well adapted for the outer covering of buildings. On the-other hand, the extreme edges of the boardsor slabs made from this material are more or less fragile, and therefore,'it is desirable to protect them from the weather and from rough usage.

Owing to this fragility and to the unusually porous nature of the material said edges, unless special precautions are taken, are unsuited forbeing-fastened, like other boards. on the sides of houses; and further, even when fastened in place they will rapidly deteriorate under the weather, unless precautions are taken to protect them.

Accordingly, thedooards .of insulite such as 6 and Tare laid'ov er each other as illus-.

trated in Figs. land 3, and their extreme meeting edges such as 8 are'covered by a .metal piece indicatedas at 9. This metal piece is conveniently struck up by any suitable dies, it is provided with faces 10 and 11 at substantially right angles to each other,

mvith projections. as best shown in-Fig. 4.

in order to facilitate the biting in of the pieces 9 as will be clear from the drawings.

The strips or members 9 are of a length equal to the width of the insulite boards,

influence of the their serrations on tlieir lips 12 and 13 extend the whole length of said strips, andat one end the sides of said strips are bent inward to form the additional pairs of lips 11. These said lips 11 are coextensive with the sides 10 and 11 as shown, and are therefore disposed at right angles to each other as will be clear from Figs 1 and 4. They extend underneath and protect the bottom edges 16 of the insulite boards 6 and? as will be clear from said drawings. I

It will, therefore, be observed that the members 12 and 13 bite into and secure a firm hold on the porous body of the insulite, that the two , walls 9 and 10 disposed at right angles to each other, effectually inclose and protect from the weather the rough and freshly cut porous and'fragile edges of said insulite, and that the underlying members 14 still further protect and secure the extreme side edges of said insulite boards 6. The entire structure results in a joint which has shown itself to be efiicient and satisfactory in practice.

Since the boards 5, for example, .overlap I each other as bestillustrated in Fig. 3,

there are left triangular spaces between said boards 6, and the inner sidewall material 4. In order to close up all cracks or spaces of this kind, I preferably employ the. wedge shaped pieces 17 which may be made of wood, of insulite 'or of other material,

but of course, these spaces maybe left open" if it is so desired, I

After the construction above disclosed has beenprovided the parts are'firmly nailed together or otherwise secured in any suit- ;able manner. 'On the interior of the build ing. I provide when, desired, additional slabs j or boaijds of insulite-n' a-terial indicated at 19 and 20, the extreme edges of which fit in between the edges of the members 1 and3 whichare offset for this purpose as best disclosed in Fig. 2. After the slabs 19 and 20 have been thus placed, any convenient plastic material, such as plaster 21 may be applied directly to the insulite and thus the house is effectually sealed with an airspace 22 between its inner and outer walls.

It is obvious that those skilled in the art may vary the details of construction, as well as the arrangement of parts without departmg from the spirit of the invention, and therefore, I do not wish to be limited to the above disclosure except as may berequired by theclaim.v

' \[Vh'at I claim is In a building the combination of corner supports; a side wall joined to said supports; a second side wall joined to said supports and making an angle with said first named side wall; a set of overlapping porous insulite'boards having fragile edges JOHN SHAW.
