ORNAMENTAL PANEL OR COVERING.

peciflcation of Letters Patent.

Patented Aug. 5, 1919.

Application filed May 23, 1918. Serial No. 236,165.

To all whom it may concern:

Be it known that I, Join: K. SHAW a citizen of the United States, residing at inneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Ornamental Panels or Coverings; and I do hereby 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 it appertains to make and use the same.

This invention relates to ornamental panels or Wall coverings of fibrous material, and has for its object to strengthen and beautify said panels in a manner more officient and less expensive than those heretofore proposed.

With these and other objects in view the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly pomted out in the claims.

Referring to the accompanying drawings forming a part of this specification in which like numerals designate like parts in all views;

Figure 1 is a diagrammatic plan view of a finished panel showing one form of fastening strip;

Fig. 2 is an enlarged sectional detail view of the panel material taken on the line 2**2 of Fig. 1;

Fig. 3 is a view similar to Fig. 1 but disclosing a different form of fastening strip;

Fig. 4 is a sectional view of a further modified form of fastening stri Fi 5 is a view similar to Flg. 4 of the mod1 ed form of fastening strip shown in Fig. 3;

ig. 6 is a sectional view similar to Fig. 2 but showing another form of fastening strip; and

Fi 7 and 8 are each sectional views showing still further modified forms of fastening strips.

1 indicates sheets, slabs, blocks or other shapes of'the fibrous paper board material known on the market as insulite, 2 the 'oints that exist between the individual locks when they are laid on a support 2', Fig. 6, to form aipanel or wall covering, and

30 and 40, 50, 60, and different forms of fasteners that may be used in securing the end portions 6 of said blocks together as Well as in protecting and hiding their joints or seams 2.

In order that the invention may be the more clearly understood, it is said the a or board material known as insulite difl rs radically from the ordinary paper boards of commerce in that it is very porous, and therefore it has unusually high heat insulatin and sound deadenin properties. Its spec c gravity is often not lngher than, say, two tenths or three tenths and therefore it resembles cork in many of its physical properties. But these most desirable properties ive rise to a structure whose edges are very ragile or brittle and easily so injured as to present a ragged appearance. This is owing to the unusually lar e and long fibers that are employed in maklng the board, and to the rather imperfect natural bonding of these fibers at the extreme edges so that the latter tear or break if subjected to rough usage. In other words one class of fibers going to make up these boards may be, say 1/8 of an inch wide and 1/2 inch lon so that they are sliver like; another set of ers are thread like in that they may have a diameter of from 1/32 to 1/64 of an inch and may be from 1/2 inch to 1 inch long or longer; a third set are hair like in that they may have a diameter of say from 1/100 to 1/200 of an inch and a length of say from 1/2 inch to 1 inch or longer; while a fourth set of fibers are or may be identical with the fibers used in making paper.

In dealing with a structure such as that just disclosed, it is found in practice that its surface such as 7 and 8 ma be highly ornamented as by coloring or y covering with plastic materials, but the extreme edges of the individual blocks do not present such sharp, clean surfaces as to make it an easy job to fit them together in a way sufliciently close to present a pleasing appearance.

According to this invention, I avoid the above difiiculty and at the same time protect and stren hen the end edges 6 by proceeding as fol ows: I make no effort at fitting the individual bloeks closely together,

but merely let the joints or seams make such an appearance as a rapid handling of the material will produce, being carefuhhowe\"er,t0 see that such joints are notwider than will be safely spanned by the heads suchas 10, 11 and 12 of the fiastening strips 3, 4 and 5 respectively.

After said blocks 1 are thus brought together, a fastening strip such as 3, having a shank 13 and provided with the barbs 14:, is thrust down into. the, seam or,.j.oint 2,.and itshead forced down into contact with the comparatively porous,- sdft, =or "compressible material of the blocks 1.

I prefer to 'provide an edge member such as 15 whichmay be 'readll'y foreed into the body of the material 1,and'thereby more firmly unite said blocks.

Should the head 10 be concave as-shown in Fig. 7,it=n1ay be*fille!d -with a plastic or other material to match the coloring'or surfacing of the'bloeks -1, or it may be itself of such a color and =finish as to *needno filling. *I fthe blocks 1 aresutfaoedtoimitate stone, the oracklfi, Fig. 5, can be conveniently filled with a plastic to appear asa bonding material, but'in such cases-the head '12 will *be preferabl flattened oat against the surfaces of said. looks or tiles 1.

ln the somewhat modified dot-mathema- .ing strips 1 shown 1 in Fig. 4, thesin le piece of sheet {material instead of being oldedwn itself to form the pron'gfm'ember as in -Fig. 2 is bent upon itself to form the-head, and 'the latter is convex-as'shewn.

In the still furth'er modified form of fastening strip shown in Fig.5,'the prongconstruction is similanto 'thatshown in Fig. "2, but the head is made of 'a'single thickness, While the prong'is formed by doubling the metal upon itself, and instead its extreme edges 17 are somewhatshar so that-they may be forced int-0 the body of the material 1.

In the modified form of construction shown in -Fig. 6,the head 20 is rounded as shown, it entersa correspondingly rounded cavity 21' in'the materidL andbetweem the ends of itsgprongs'23 I ihsei t a-w edge flbr other spreader, 11 order to make the 'ibaf'bs 25 bite into the material and also 'toloek "them in place. Somewhat the same looking effect is produced when 'p'laster -25 is inserted into the 'orack or opening '16 in ig. 5.

The modified form of fastener shown in Fig. '7 is provided with a pron 27 (if a single thickness of-metal and Wit spreading wings 28 formed by folding the nletal upon dtseltf :as shown, thus pmduding the space 29 which may be ornamented as described.

{In a the still further modified ifiorm of fastener 80 shon'vn1in Fig. *8,'the *head *30 is of-astriangularoross seetiion and the shank 31 is of he sumo general construction shown in Fig. 2.

-Ilrom the foregoin it will now be clear that Danny employ a Ell-g6 variety of 'iastening strips for hiding irregular joints 2, while at the same time enhancing the appearance of the panels and strengthening the whole surface in general. In all the fOI'I'l'lSfhORVOl/GI',tilt! strips are made of very thin metal, in order that they may be readily wedged .into the seam or joints (-2, between the looks I, and a plurality of thin yield- --ing spring prongs projecting toward the head portions are provided, Which enter the insulite edges and aid in holding the head portions in place.

The'fastening strips are out into different lengths such-as 19 and 20, see Fig. '1, or' they -may be of uniform lengths, and beveled =at the-ends as illustrated at 21, Fig. 3.

LIn an ornamental covering, the combination of a plurality of body portions composed of porous paper board material known as insulite, having fragile edges-disposed with adjoining meeting edges; and a fastening =str1p provided with prongs'engagin said fl3jgll'6 edges occupying the space etween said meeting edges, and with -a head contacting "with and overlying and concealing the material adjacent said meeting edges, substantially as described.

2. *In an ornamental covering, the combination of a plurality "of porous 'bo'dy portions coin used of paper board material known as nsulite, having fragile edges disggsed with adjoinin-g meetin'g edges; and a 1 steningstrip provided with an extension haVingbatbs entering said fragile'edges and occupying the space between said meeting edges, and with a head contacting with, overlying, entering and concealing the fragile material adjacent said meeting edges, sabstamiall as described.

3. In an ornamental panel the coin-bination of a plurality of porous, fragile insulitebody portien-s lilisposed Withtheir fragile edges "in close pro xirnity to each other forrn'ing seams; fastening strips provided with mngs'oceapyin said seams, engaging the fragile edges thereof, and disposed at right angles to each other, said strips also rovidedwith strip like headsaddptd to 1 e pressed against, to extend over, rotect and conceal *the fragile material -ajace'nt said seams, substantiall as described.
