larly for use in sound deadenlng construe-l tions. The invention is disclosed in my abandoned application, filed August 11, 1927, Serial N o. 212,265 of which the present application is a division and is also disclosed in 1929, filed February 25, 1929.

The principal object Aof the invention is to provide an improved furring strip of economical construction which is adapted toengage andsupport the metal sheets or tile in the completed installation.

A further object of the invention is to provide furring strips along certain forms of which the tlle may be moved to or from a given position whereby all of the' tiles can be removed without mutilation, other than possibly one or two tiles of each row or tier.

Other objects relate to various features of construction of the furring strips', as will become ap 'arent from a consideration of the following specification and drawings,

wherein: y

.Fig 1 is a erspectivev view of a form of the improved urrmg strip formed of a single piece of sheet metal,

Fig. 2 is 'a view showing-the manner in whic a strip engages and supports the contiguous foraminous tiles which support the sound deadening material (not shown) Fig. 3 is a perspective view of a suitable i form of tile,

Fig. 4 shows a modified form of furring strip in which the legs are formed of strips of metal separate from the back or base member, and

Fig. 5 illustrates an additional modification of the invention.

In Figs. '1 and 2 of the drawings, the furring strip is shown formed of a single piece of sheet metal havin a back or base portion 10, the sheet materia being folded back substantially parallel to itself Vand preferably, although not necessarily, almost into contact with the underface of the base, then as best shown in the sectional view, Fig. v2. The metal faces. A

In Fig. 4 the construction is similar to that shown in Fig. 1, except that the back memberV 1927, Schuim-818,966. Divided and this application ined January 85, 1928. Serial No. 849,453.

tudinal ledges .or supports 12 for supporting may be of sheet metal having flanges 14-which are provided with ears 15 and are adapted for enga ement with the ledges 12 as shown clearly in ig. 2. The material of the furring strip is resilient, whereby the legs can be sprung apart suiciently to permit the insertion of the flanges 14 of the tile 13 and thus effect the inter-locking with the ledge 12 of the ears 15j, as will be apparent. Although the upwardl bent ed es o the legs are shown folded bac fairly c ose to the legs themselves, with `only a small clearance between these resilient members, it is evident that the extent to which said yis also bent in a direction nearly at ri ht i parts are vbent is not Iespecially important as long as they are bent back far enough to insure a positivel locking `en agement `between saidedges and said ears. lso`a smooth bend at the lower end is preferred, to provide a flaring or tapering inlet at the lower end of the furring strip to facilitate the insertion of said legs 14. Openings 16 are provided forreceiving fastening means such as screws, nails or toggle bolts by means of which the furring strips are secured to the wall or ceiling sur- 17 is formed of a strip separate from the strip of which the legs 18 are formed. The legs are provided with anges 19 which are s uitably secured to the back 17 by any approved means su'ch as welding, whereby the fabri cated strip is made, an integral unit. v

'In Fi 5 a modified form of the furring strip is s own in which the legs and back are formed of a single piece of resilient Sheet Aas material. In this form of the invention, the free edges of the legs are not folded upward*- v ly to form thesupporting ledges shown in the other li res, but slots 'or' openin 20 are formed in the legs. 21 to provide edges or 'WILl surfaces 22. These ledges 22, like the ledges of the previously described forms of themvention form horizontal supports for the ears of e tile, permitting inter-locking enga ement. A lthough I have shown certain features of my improvements for the purpose of ilustratin, itv will be ap. arent that chan ay be made therein wit out departingfrom the spirit of thel invention as defined inthe j appended claims. .l WhatI claim is:

1. A furring strip formed of sheet metal comprising a supporting base section and a, pair of resilient 1e s extending therefrom, converging toward t eir free edges and having means for positively securing and supporting one ormore articles inserted therebetween, by a movement toward said base section.

2. A furring strip of sheet'metal having a -base member adapted to be secured to ,a support and a pair of-resilient legs integral therewith, said legs extending from said base in a direction `away from sald support and con verging toward their free edges and being adapted to b e sprung apart for the insertion therebetween of members tobe supported thereby, each leg having at least one ledge substantially normal to the plane of the leg for eifecting positive engagement with one or more of said members.

3. A furring strip comprising a base adapted to/be secured to a support, a airoflegs extending from said base in a irection away from said support, said legs bein spaced apart along correspondin edges an bearing l against each other along t `eir opposite edges, each leg havingmeans for supporting one of two articlesinserted between said` legs legs being resilient and tending normally to exert spring pressure against said articles to prevent disengagement of the same from the supporting means.,

4.45 4.- A metal furring strip comprising abase section and two resilient leg Lsections sup ported thereby, each le section having a free articles inserted t said 1,sas174 to a backing strip, vthe leg of each section being folded inwardly upon itself to form a double portion resiliently bearing against the other double portion.

v 7.v As an article of manufacture a metal furring strip having a lateral portion adapted to be secured to"a plane surface and having two ind/ependentl movable resilient leg members spaced .slig tly apart with ledgeA forming means thereon, said ledges forming sitive engaging means for articles inserted tween said members ,for resisting stresses exerted on said articles in a direction substan- :Elly parallel with the plane of said memrs. l 8. As 'an article of manufacture, a sheet metalfurring strip T sha said strip comprising L s aped sections disd in crosssection,

posed back to back and s aced slightly apart at theirbases, the lego each section being folded inwardly to form a double portion resiliently portion.
