ness and embeds itself readily in the studding especially if one of the nails 21 for fastening the strip is passed through the strip at this point. Otherwise the studding may be notched out with a saw or chisel. However, it is not believed that this preliminary step will be found necessary. The flanges being turned in toward one another and presenting rounded edges to make the strip easier to handle are arranged to flatten out, as indicated at 22, and to become slightly em bedded in the studding. There is thus practically only the thickness of the sheet metal of which the strip is formed projecting from the studding which in no way affects the workmanlike application of the wall board. The strip 16 has a plurality of spurs or barbs 23 struck therefrom preferably in staggered relation which embed themselves in the wall board when the same is applied. When a trimming piece such asthe chair rail 14- is nailed to the studding as by means of nails 2a which are passed preferably through the header strip 16, the wall board is obviously retained quite securely against bulging or warping. By providing two rows of the spurs or barbs 23 the edges of abutting panels lappedby the strip are properly gripped and retained.

In Fig. 3 a modified form of strip is illustrated at 16' having a corrugated cross section for the purpose of affording the necessary stiffness 0r rigidity to properly support and back up the wall board. As shown at 25, this form of strip readily flattens out onto the studding when the nails 21 for fastening the Between the studding the strip retains its original corrugated form as illustrated. This form of strip is also preferably provided with spurs or barbs 2 3 to become embedded in the wall board to grip and retain the same.

In Fig. 4 still another form of strip 16 is shown which is flat in cross section with the exception of two longitudinally extending ribs or corrugations 26. The latter give the required stiffness and rigidity and are arranged to become flattened out more or less, as indicated at 27 when the strip is fastened tothe studding as by means of the nails 21. The normal ribbed cross section is retained between the studding. In this form, as in the others, the spurs or barbs 23 are provided preferably in two rows to become embedded in the edges of abutting wall board panels to grip and retain the same.

It is also contemplated, as stated above, to provide header strips of wire rod construction, as shown in Figs. 5 and 6. In the form shown at 16 a plurality of barbs 23 are pro- Vided at regularly spaced intervals to become embedded in the wall board for the same purose as the barbs on the other forms of strips illustrated. The strip 16 is obviously adapted to be fastened to the studding by staples and in fastening will easily become embedded in the studding to a sufficient depth so that the wall board will lie practically flush over the same. The strip 16 is similar to the strip 16 with the exception that two sets of barbs are provided in planes substantially at right angles. That is, alternate barbs occur in one plane while intermediate barbs occur in the other plane. Thus, if the rod becomes twisted so that one set of barbs does not project properly to become embedded in the wall board, the other set of barbs will be properly disposed and no special precaution has to be taken in the fastening of the strip as might have to be taken in the case of the strip 16.

It will appear from the foregoing description that I have provided a novel fastener for use in the application of wall board which considerably reduces labor cost and minimixes the cost of materials. The strips in addition to being easy to handle and fasten into place give the desired even nailing surface for the wall board panels and serve to grip and support the wall board so that warpage and bulging are positively avoided.

I am aware that changes in the form and construction of the strips may be made and substituted for those herein shown without sacrificing the more important advantages described. It will, therefore, be understood thatthe invention is in no way limited to the specific forms illustrated.

I claim:

1. In a wall or similar construction, the combination with ordinary spaced wooden studding and wall board arranged to be nailed to the studding, of thin, stiff, metallic strips fastened cross wise onto the edges of the wooden studding under the wall board, each strip extending in a continuous length across a plurality of studs with at least a portion thereof preferably embedded in the edge of each stud so that the strip projects only slightly therefrom and a substantially flat surface is afforded for the application of th'ewall board, and all of the strips together serving to back-up the wall board between the studding and take the place of separate wooden header pieces otherwise inserted and nailed between the studding.

2. In a wall or similar construction, the combination with spaced studding and wall board arranged to be nailed to the studding, of thin, stiff, metallic strips fastened crosswise to the studding under the wall board, each strip extending in a continuous length across a plurality of the studs so that all of the strips together serve to back up the wall board between the studding and take the place of separate wooden header pieces otherwise inserted between the studding, and each strip having spurs or barbs projecting therefrom arranged to imbed themselves in the wall board so that all of the strips together serve also to hold the wall board against creeping.

3. As a new article of manufacture, a sheet metal header strip arranged to be fastened crosswise to studding to back up wall board nailed thereto, said strip having one or more longitudinal ribs formed in the sheet metal thereof to insurestraightness as well as lend sufficient stiffness to resist the tendency for transverse bending under strain, and said strip having two rows of spurs or barbs struck from the sheet metal thereof on opposite sides of a longitudinal median line arranged to imbed themselves in the back of a piece of Wall board or in the marginaledge portions of two abutting pieces of wall board.

4;. As a new article of manufacture, a sheet ness of the strip as well as lend sufficient stiffness to resist the tendency for transverse bending under strain, the said rib being adapted to imbed itself readily in the studding in the fastening of the strip thereto, and

said central rib arranged to imbed themselves in the back of a piece of wall board or in the marginal edge portions of two abutting pieces of wall board, and said strip having longitudinally extending flanges on the opposite edges thereof bent inwardly toward one another so as to present rounded edges on the strip, making it easier to handle the same as well as to afford additional stiflness, the said flanges being arranged to be flattened out on the studs and to become slightly imbedded therein in the fastening of the strips to the studding. v

In witness of the nature.

foregoing I aflix my sigsaid strip having two rows of spurs or barbs struck from the sheet metal thereof on opposite sides of said central rib arranged to imbed themselves in the back of a piece of wall board or in the marginal edge portions of two abutting pieces of wall board.

5. As a new article of manufacture, a sheet metal header strip arranged to be fastened crosswise to studding to back up wall board nailed thereto, said strip having a central longitudinally extending rib crimped in the sheet metal thereof serving to insure straightness of the strip as well as lend suflicient stiffness to resist the tendency for transverse bending under strain, the said rib being adapted to imbed itself readily in the studding in the fastening of the strip thereto, and said strip having longitudinally extending flanges on the opposite edges thereof bent inwardly toward'one another so as to present rounded edges on the strip, making it easier to handle the same as well as to afford additional stiffness, the .said flanges being arranged to be flattened out on the studs and to become slightly, imbedded therein in the fastening of the strips to the studding.
