FURRING STRIP Filed Jan. 24I 1929 Patented Dec. 3, 1929 UNITED STATES all PATENT OFFICE nowa n. weiss, or MADISON, WISCONSIN, AssIeNon To o. r. nunenss :LABORA- nonies, INC.; OF MADISON, wisooNsiN, A CORPORATION or DELAWARE A FUaniNe STRIP Application ledf January 24, 1929., Serial No. 334,820.

rlhis invention relates to improvements in 'turring strips adapted for use in sound deadening construction similar' to that dis closed in the application of Ralph Forbush Florzris, Serial No. 212,265, tiled August 11, 192

'llhe principal object of my'invention is tO provide an improved urring strip oit economical construction which is adapted to engage and support the metal sheets or tiles which carry sound deadening material,` the urring strips being concealed by the tiles in the completed installation.

A t'urther obj ect of the invention is to provide turring strips along which the tiles may be moved to or from a given position whereby all ot the tiles can be removed without mutilation other than possibly oneor two tiles of each row or tier. i

@ther objectsrelate to various eaturesof s construction of the furring strips, as will become apparent trom a consideration ot the following specification and drawings, wherein: Y

'F ig. 1 is a perspective view of a form of lthe improved urring strip formed ot a single piece ot sheet metal,

Fig. 2 is a perspective view oi a suitable :torno of tile,

Fig. 3 is a view showing the manner inwhich a strip engages and supports the con- Y tiguous oraminous tiles whichsupport- 'the sound deadening material Q(not shown).

Fig. 4t is a longitudinal sectional lview showing the manner in which a strip engages and supports theforaminous tiles.

Fig. 5 illustrates a modification of my improved :turring stript i lin Fig. 1 of the drawing, the turring strip is shown to be tormed of a single piece ot sheet metal bent substantially at lright angles to form a strip of invertedl shape in cross section, and having a back or base portion 1 and a leg portion which isy divided into' sections 2, 3, 4, etc., by spaced cuts which erV tend transversely of the leg portion Jfrom the edge to a point removed from the bend of the angle. A bead or groove 5 isr rolled Or otherwise impressed Ylongitudinally into `the leg portion a short distance from the edge but is reversed in direction with each successive section. The material of the furrmg strip is reslllent and each successlve section is bent a slight amount in opposite directions so as to having a-pair of opposite side Hanges 8 which4 are provided with inwardly extending longitudinal beads or grooves 9 which may be disposed aboutmidway between the upper and lower edges of the danges. T he tiles may also be provided with llanges 10 on the remaining sides although these latter anges may be omitted, as`desired. The tiles may be perorated as shown and may contain soundtiti deadening material such as is disclosed in said l earlier application., A

In the operation of installing the tiles a flange 8 of one-tile may be inserted between the sections Ot the urring strip in a manner such that sections 2 and l are on one side and section 3 is on the other side. The tile is advanced between the sections untilbead 9 ot the tile engagesbead 5 of the turring strip. The opposite Hangs 9 of the same tile may then be,.similarly inserted between the sections of a second turring strip parallel to and spaced the width of a tile from the tiret urring strip. A second tile may now be similarly inserted between the sections ot the rst turring strip in such a manner'that one of its beaded anges is in contact with the beaded tange of the tile already in place.`

Figs. 3 and 4 illustrate the manner in which two adjacent `tiles engage a furri'ng strip and are maintained in position.

In an alternative method of installation, two tiles may be placed side by side with beaded Hanges 8 1n contact and the two flanges 4inserted together between adjacent sections 2, 3, 4, of the furring stripuntil beads 9 of the tiles engage beads 5 of the furring strips. The spring pressure between sections, 2, 3, 4 holds the flanges 8 rigidly in place.v The opposite flange 8 together with the beaded flange of-an adjacent tile may be similarlyinserted between the sections of a second furring strip parallel to and spaced the width of a tile from the first furring strip.

The tiles may be slipped back and forth longi! tudinally of the furring strips so that abutting tiles may be firmly pressed against each other to make tight joints, it being understood that the beaded leg sections are of considerably less length than the beaded tile flanges so that the latter will be continually engaged by one or more .of the sections, i. e., one flange overlaps a plurality of leg sections to prevent accidental disengagement. To dismantle an acoustical metal ceiling or wall using my improved furring strips it is necessary to destroy one-tile only, after which the remaining tiles may be removed by springing apart the sections 2, 3, 4, and withdrawing flanges 8 from between them, using a suitable tool if necessary.

In Fig. 5, a modification "of my improved furring strip is shown'which is formed of a single piece of s'heetinaterial having a base or supporting portion 11, the sheet material being folded substantially into contact with.

one .face ofthe base portion 11, then in a direction nearly at right angles thereto to form legs v12, thus giving a strip -T'shaped in cross section. The legs l2 converge as shown and are provided with longitudinal beads 13 for supporting tiles, the flanges 8 of which are inserted between the legs 12in a manner similar to that heretofore described.

Although I have shown certain detailed features of my improvements for the purpose of illustration, it will be apparent that changes may be made therein without departing from the spirit of the invention as defined l in the appended claims.-

What I claim is:

'1. 'A metal furring strip having a supporting base portion and a leg cut transversely of its length into resilient sections adapted to be sprung' apart for inserting therebetween one or more articles to be supported by the strip,1said sections having means for Securing and supporting said articles.

2. A metal furring strip having a supporting base portion and a leg cut into sections,

said sections being adapted to be sprung apart for inserting therebetween the articles to be supported by the strip, and longitudinal beads in said sections to engage similar beads in said articles. v

3. Affurring strip formed of sheet metal comprising a baseportion adapted to be secured to a support, a leg integral with said base andbeing partially cut transversely of its length into sections, said sections being adapted to be sprung apart for inserting therebetween the articles to be supported by the strip, and longitudinal beads in said sections to engage similar beads in said articles.

4.. A. furring strip formed of sheet metal comprising a base portion adapted to be secured to a support, a leg integral with said base, said leg extending from said base in a direction away from said support and being partially cut transversely of its length into sections, said sections being adapted to be sprung apart for inserting therebetween articles to be supported, and longitudinal beads oppositely impressed in successive sections to engage complemental beads in said articles.

5. A furrin'g strip comprising a base and a plurality of leg sections supported thereby, each of said leg sections being disposed in one or the other of two converging planes and having beads therein for engaging articles to be supported by said strip.

6. As a new article of manufacture, a fabricated sheet metal furring strip L Shaped in cross section, one leg of said strip being a plane section, the other leg being partially cut transversely of its length into a plurality of sections, each successive section being slightly sprung in opposite directions, and longitudinal beads in each section impressed in the direction toward which said section is sprung.

7. As a new article of manufacture, a metal u Y furring strip having a base supporting section and a leg cut into a plurality of sections, said sections having beads extending longitudinally therein.

8. A urringstrip comprising a base and a leg, said leg being dividedinto a plurality of beaded sections, the beads of successive sections being oppositely disposed for engagement with abutting complementally beaded portions of articles to be supported thereby.

9. The combination with a beaded flanged article of a fui'ring strip for slidably supporting the same, said strip comprising a base and a plurality of 'beaded leg sections, the' alternate sections being similarly beaded for complemental engagement with thc bead of said flange, and each being of a length less than said flanges whereby the bead ot' the latter will continually engage one or more of the beads of the complementally beaded sections as the article is moved longitudinally of said strip'.

In testimony whereof, I have subscribed
