ATTORNEY Patented Sept. 13, 19 32 UNITED FRANK scor'r caownuns'r; or Los \ANGELES, CALIFORNIA v BUILDI G oonsriaucrlon Application-filed April 9,

My invention relates to building construction, and more particularly to furrlngstrips, and is referred tolherein' as an improvement upon the form of my invention shown and described in'my co-pending application for U. S. Letters Patent for Building construc-' tion, Serial No. 257,366, filed February 27, 1928. y

My invention is essentially directed to a new, novel and useful furring strip, and;

it will adapt itself torelative movements be:

tween the studs and a plastic wall surface of which the furring stripis an incidental or coacting element of said wall surface, thereby insuring the strength of the wall and'pre-' venting cracking. thereof during settling periods or by virtue of climatic changes;

A further object of my invention is to pro-' vide novel positively-functioning means. for

attaching the furring material to the studding, which said means can be quickly driven into the individual. studs as the furring ma--. terial is held in position,

Another important object of the invention in conjunction with my improved furring.

strip is a co-acting connecting device or fastcning whichrcan be applied toflthe stud by" an unskilled person.

v A still further object of the invention is to provide, an attaching device for'the' furring which can be driven into position by "one standing in front of thematerial and without any necessity of any guess work as to its point of application tothe studding.

In the accompanying drawing,

Figuref is a of Fig- IQ i Figure 5 is a perspective view of the fastening orattaching device;

Figure 6, is a View similar to Figure 5 of a further form of attaching device; and V y Figure 7 is a view similar to Figure 6 of a still further form offastening device.

On reference to Figure 3, it is observed that the furring strip is ofthe type'made upfof" equidistantly space'daapart horizontal wires 10 and Vertical equidistantly spaced-apart wires '11, the associationofthe latter with the former beingsuch that fabric is provided with relatively large rectangular interstices 12. The horizontal wires 10 are all formed: with inwardly offset U branches 13, the same including a long lead 1 1' disposed in parallel? section on line ism with the body or front face of the lathingv. .7

strip, and connecting end portions'l5, 15, it being preferred that the said end portions extend at right angles to the front face of, the furring strip. In practice, it is'found suitable for my purpose that the portions 15 pos-' sess a length of about five-sixteenths of anv inch and that 'the lengthof the lead 14 bejapproximately three inches. This allows ample clearance between an applied wall surface which I will subsequently refer to and the studs that will prevent any rough plaster from in any way interfering with the action of my invention when applied. a p In Figure lit'isobser'ved that the U- shaped portions 13 are arranged in spacedapart vertical rows so that one row will co-incide with a respective stud with which itis associated and wherein the leads 14 traverse in horizontal directions the front face of the stud. Injorder that my improved furring strip, when applied tothe studs A, Figures 1 and 2, may be free to compensateitself for any relative movement set up in the studs or any stresses transferred thereto through usual causes, I provide a fastening or co'nnector'16, the-same being staple-like and pro-' vided with

legs

17, 17, adapted to straddle the Y lead 14 and to be driven into the stud, and as illustrated these legs are joined together-by a loop 18 which, when the legs '17 are fully applied, receives the lead 1 1 in embracing rela' 14 of the furring strip, the short terminal 22 tionship thereto butwith clearance between the walls of the loop and the exterior annular surface of said lead, as shown in Figure 4.

In this manner, it manifestly follows that the connection between the stud and thefurring strip is flexible and that there is provision made for movements between the furring and its studs forsatisfyin'g movements in' all di rections," preferably movements in a horizon 'tal direction. 7

In Figure 2,:I have illustrated a wall surface B applied in the customary manner to its lath C, the latter connected at Din any suitable well-known manner with the fur: ring material. wall surfaceso that it will positively accommodate itself to any movements in the frame of the building so as to avoid the formation of cracks in the surface and to adequately 1nsure the surface against und'ue'damage.

" In Figure 6 the fastening 19 has a shank 20 adapted to be driven into a stud andthe said shank may be of a flexible wire type wherein it may bebent over at 21 to form a loop for thereception of the aforestated lead of the loop preferably formed with a fiat head 23 adapted to come againstan adjacentsurface-of the stud when the fastening is fully applied. The loop is proportionedso as to give clearance between its walls and the annular surface of the lead 14 from one end of. thelatter to the other, as is also the casein the" preferred embodiment of -my invention. fFigure 7 shows a'still modified form of fals tening consisting of a pointed 1 shank 2 4 adapted to be driven into a stud'and atone endthe shank'is formed with a driving head 25 which, when struck with a hammer or other suitable tool, will cause the point of the fastening to find proper purchase with its joist. As an integral part of the head 25', .I have shown a branch arm 26 whichterminates in a supplemental spur 27'of short length as' compared with the length of the i shank 24. f This is adapted to be driven slighttween all surfaces of the loop thus formed 1y into thejoist and to stop when the sho'ul'- der 28 thereof reaches the stud. In this way,

the sp ace'under the head 25 functions as a loop 'andthere is a permanent clearance ber and the coacting lead 24 of the furring strip which passes through the loop.

I do not wish to be'limited to any particu lar form of fasteningwhen carrying the invention into practice, as I am primarily concerned with the form of furring in association with any suitable well-known means that willalford a way of setting up freedom of ac- ,3 tion between thestuds and the furring strip when the latter is applied, all in order that the aforementioned relative movements between these parts may be positively accommodated without in any way affecting an ap-. plied'plasticwall surface. f

I have now suspended the- I claim as my invention:

"1. Furring material having portions ofii set from the plane of the body of the material and adapted to come against the studs of a building frame, and means for loosely attaching the material to the studs at thesaid offset portions, thereby permitting the studs and the materialto move relatively when the furring material is incorporated with a plastic wall surface,

- 2. 'Furring material having interstices defined partly by straight portions of the ma teri'al, andmeans adapted to be attached to the studs of a building frame and having loops to freely'receive said straight portions and. to permit of a relative lateral movement of the portions withrespect to the loops when thematerial is attached toithe studs.

. 3 Furring material having interstices defined partly straight portions of the materiahand means adapted to be attached'to' the studs of;..a;building frame and having loops to freely receive said straight portions and to permit of a relative movement of the portions with respect to. the loops when the material is attached to the studs, the said 7' straight portions being offset in one direction awayfrom the plane of the bodyof the material. t I

4. Inlbuilding construction, frame studs; a plastic wall surface; fur-ring to which said wall surface is secured; and loopmeans'secured to the studs and loosely connecting the.

furring to the studs to permit movement of the studs relative to the wall surface.

5. In building construction, means for establishing a flexible connection between furring material and the'studs of a building frame, comprising furring material having portions traversing the studs and spaced apart from the body of the material, and pointed devices connected with the studs and having loops freely receiving'said traversing portions for movements therein.

6.. Furrmg meanscomprlslng a spaced apart pairs of laterally projecting branches and a portion connecting each pair of branches, disposed parallel to and offset from the planeof the strip, andan attaching device having a head loosely receiving the connecting portion of the' strip,and a shank length of bendable material bent at intervals to provide capable of being driven into astud or joist to secure the strip thereto yet permit limited movement'of the stud relative to the strip from the latter, while permitting relative movement between the studding and furring to prevent fracture of the plaster.

8. Wall construction comprising studding; furring; plaster carrying lathing secured to the furring with the plaster spaced from the latter; and a loose connection between the studcling and furring coacting with the latter to support the furring from the studding and enabling the studding to move relative to the furring to prevent fracture of the plaster.
