(Cl. 'Z2-118) 3 Claims'. 1

This invention relates to furring strips more particularly adapted for stucco-covered walls.

Anobject of the present invention is to provide new and improved means whereby uniformity of application of stucco or similar material to a wall may be obtained without the need for great skill on the part of the plasterer.

Another object of the invention is to provide a novel and improved furring strip for use in supportingr one or more layers of wire mesh to prepare afwall for receiving stucco.

-Another object of theinvention is to provide wire mesh support furring for the ultimate provision of a stucco-covered wall that resists weave and. shock and is reproof to a high degree.

The over-all strength of a stucco wall is relatedV to the uniformity of: application of the scratch and finishing coats. An uneven primary or scratch. coat will result in a wall having strong tendencies. to crack and to yield, at its weaker parts to shock, etc. This. invention, therefore', seeks to provide simplev means, readily usable by apprentices and other relatively unskilled helpers, for preparing awall to receive uniform layers of scratch and :finishk coats of stucco.

YMy invention also has for its objects to provide such means thatv are positive in operation, convenient in use, easily installed. in a working position and easily disconnected therefrom, eco-V nomical of manufacture, relatively simple, and of general superiority and serviceability.

The invention also comprises novel details of construction and novel combinations and arrangements of parts, which will more fully ap.-

pear in the course of the follow-ing description.r

However, the drawings merely show andthe following description merely describes one embodiment of the present invention, which is givenl by way of illustration or example only.

In the drawings, like reference characters designate similar parts in the several views.

Fig. 1- is a broken view, as seen from the outer face of a wall, showing the manner of application of theinvention invarious stages through thewall thickness.

Fig. 2 is an enlarged cross-sectional view as taken on the line 2-2 of Fig. 1.

Fig. 3 is a broken side view of a furring strip shown in Figs. 1 and 2.

Fig. 4 is a broken pattern view of said furring strip.

The wall, upon which the instrumentalities of the invention are applied, may be variously constructed. As shown, said wall comprises wooden studs 5 covered on their outer faces by tar paper sheeting 6 or the like.

According to the invention, the wall has ap plied thereon a plurality of furring strips 'l of novel form to support a Wire mesh 8 in proper spaced relation to the sheeting 6 and for the purpose of reinforcing and` guiding the uniform application of a base or scratch coat or layer of stucco or like material 9', and a plurality of furring blocks Il] mounted on said furring strips tomount and space a second wire mesh Il from the'rst wire mesh for the purpose of reinforcing and. guiding the uniform applicationof a second v or ni-shing coating or layer I-.I-a of stucco or like material.

The furring strip which is shownI in the draw-f ing,I and with more particular reference tofv Fig. 4, comprises, generally, an integral light-gauge metal strip'v formed with spaced longitudinal and parallel portions I2 and longitudinally spaced connecting portions I3\. Said strip, along fold lines I4 and I5, is adapted to be formed` or bent, as in Figs. 2 andl 3 to provide a saddle I6 having. the shape of an inverted U` Between each pair of fold lines I4 and I5 there isdeinedfa side wall I'I having edges each formed with a-notchf I8, and between fold'` lines I5 there isA defined a top plate I9. The connecting portion, I3 is further formed with. tabs 2liA as longitudinal extensions of the topl plate I9 and said tabs are' normally angularly and downwardly directed as indicated indot-dash lines in' Fig. 3, being bent onz a fold line 2t.

Each of the longitudinal: portions I2 is provided with a plurality of spaced holes 22V for nails 23 employedl to fasten the strip l in place. Another and optional means oi" fastening said strip, as shown in Fig. l, comprisesv av large-headed nail 24A arranged tolcatchv adjacentedges of said portions I2 substantially as shown. The walls I1 are also preferably provided with holes 25 and the top plate i9 with a hole 26.

In practicethe strips 1, arranged in any' suit able direction, are secu-red in place by nails i3 and/or nails 24 and the wire mesh 8 is mounted in spaced? relation to the sheeting 6 by catching portions of said mesh in one notch I8 of eachy .or'most of the saddles I3, as seenin Fig. 3, and

then bending the tabs 20 inward so that they serve as clinchers for the mesh and also form closures for the interior of the saddle. The primary or scratch stucco layer 9 is now applied to an approximate thickness indicated by line 21 of Fig. 2, the closure tabs 20 keeping stucco from filling in the interiors of the saddles.

At a suitable time thereafter and when said scratch layer has dried, the furring blocks I0 are mounted on as many of the saddles I3 as is thought necessary. Each block may be cylindrical, as shown, or otherwise shaped and may advantageously be made of non-combustible composition material. 'I'he blocks are simply nailed in place by suitably long nails 28 entering through holes 26 and, in the process of nailing, the second mesh Il is caught under the heads of said nails and thereby held in spaced relation to the scratch layer by said furring blocks. Should the holes 26 become clogged during application of the scratch layer, the nails 28 will readily dislodge such pieces of stucco to fall into the interior areas dened by the saddle walls and the tabs 20. Since said interior areas are substantially free of stucco, the nails 28 meet no obstructions when being applied.

In the above manner there is provided a second outer mesh, uniformly spaced from the already embedded inner mesh, to serve as a guide for the uniform application of a second coat r layer or an outer or finish coat lla, as desired. The line 29 of Fig. 2 suggests the outer surface of such a layer.

While it is preferred to provide the furring strips as described, it will be evident that separate individual saddles may be applied for effecting the spaced mounting relationship of the wire meshes.

The holes 25 may be optionally employed for wire clips inter-connecting with the wire mesh 8 to mount the same. In this disclosure and in the appended claims, the term wire mesh is intended to include reinforcing fabrics generally, examples thereof being chicken wire, expanded metal, and various types of metal fabrics..

While I have illustrated and described what I now regard as the preferred embodiment of my invention, the construction is, of course, subject to modifications without departing from the spirit and scope of my invention. I, therefore, do not wish to restrict myself to the particular form of construction illustrated and described, but desire to avail myself of all modifications that may fall within the scope of the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. In a wall structure, a vertical stud, a furring strip formed of sheet metal and having longitudinally extending side strips and saddles spaced from each other longitudinally of the side strips, said sidestrips being formed with openings, nails passing through said openings into the stud to secure the strips against the stud, said saddles each having a at bridge, and side walls extending .from opposite side edges thereof and integrally united with the inner side edges of the side strips, the side walls of the saddles having end edges formed with V-shaped recesses and the bridge having end portions projecting beyond the side walls and constituting tongues, a first layer of wire mesh having portions fitting about said saddles and engaged in said recesses, said tongues being bent inwardly between the side walls and serving to hold the wire mesh in the recesses and constituting moi'- tar-excluding barriers for the ends of the saddles, blocks disposed against the bridge portions of certain of said saddles and formed with openings registering with the openings in the bridges, a second layer of wire mesh having portions thereon bearing against said blocks, and nails passing through the registering openings of the blocks and the saddles and into the stud, the heads Of the nails overlapping and gripping the last mentioned wire mesh to hold the same against the blocks.

2. A metal furring strip comprising longitudinally extending side strips spaced transversely from each other, saddles spaced from each other longitudinally of the side strips, each saddle having a bridge and side walls extending from the opposite side edges thereof and integrally united with the inner side edges of the side strips, said side walls having end edges formed with recesses constituting seats adapted to receive portions of a sheet of wire mesh, the bridges at each saddle having end portions extending beyond the side walls and forming tongues bent downwardly and inwardly between the side walls and extending in crossing relation to the inner ends of the recesses in position adapting them to extend across the said portions of the wire mesh and secure the same in the recesses, said tongues being of a length and width adapting them to t snugly between the side walls and thereby constitute mortar-excluding barriers for the ends of the saddles.

3. A furring strip comprising longitudinally extending side strips spaced transversely from each other, saddles between the side strips spaced from each other longitudinally thereof, each saddle having a bridge and side walls extending from the opposite edges thereof and connected with the side strips, said saddles being open at` REFERENCES CITED The following references are of record in the file of this patent:
