This inventionrelates to wall constructionsand more particularly to that typekno'wn asfurred.

walls. It relates'also to an improved form of clip used to secure the furre'd wallmembers t the furring strips or wall supports.

Furred walls are employed ordinarily to afford a straight even exposed wall surface or to provide anair space between the" base wall and'the furred wall for purposes ofsound and "heat insulation, or to presenflmatching surfaces at partitions. Anumber of systems havebeen developed to obtain a. furred wall, many :or which systemsemploywooden strips secured to thelbase wall to which strips the finishing orfurre'd' wall elements "aresecured. Other systems employ metal furring' strips or supporting members, clips being used to secure the turret! wallelements to the furring' members. It is to the latter type of furred wall" construction that the present invention relates.

It is an object of the present invention to provide a furred wall construction which may be readily and easilyerected and which willafford a secure connection between the furred 'wall' elements and. the furring strips.

It is a'further object of the invention to provide a furred wall construction which is particularly adapted for use in connection with wall boards of the lath type, such as gypsum or plaster lath, fiber board,and other similar wallelements which are'manufactured in sheet or panel form.

Another object of the invention is to provide a novel form of clip whereby the wall boards may be readilysecured to the furring members with the wall boards in coplanar edge to edge relationship.

Other advantages will appear to those skilled in this art as the description proceeds.

The invention wil be best understood by reference to the accompanying drawings, forming a part of this application, in which the same numerals refer to corresponding parts. In the drawings Figure 1 is across section through a wall'construction embodying the preferred form of the invention, the section'being taken through the adjoining edges of two wall boards witlitheimproved clip shown in plan view;

Reierringnow to'thedrawings in which one practical embodiment of the inventionis illustrated, thebase 'wall'is shown at In. This may be of concrete, brick, wood, or any other construction. To the inner side of the base 'wallllfl are secured in spacedparallel relationship iurring strips i 1, preferably in the form of steel channels such as are frequently used in' this type of wall "construction. The "furrin'g strips may, of course, beforme'd "of any metal or of wood of sufficient rigidity, the samebeing secured to the base wall it bysuitable'securingbrackets l2 and tie wires l3. The'jdetailsof the latter construe.- tion form no part or the present inventiomas any suitable means mayj -be employed for securin the fur-ring strips to the base wall.

Resting against the front or exposed sides oi the'furrin'g strips are the'wallboarcls" Man'd .M' which, in the drawings, are shown as plaster or gypsumboards which'areiorme'd of a gypsum coredisposedbe'tween paper liners. "Oi course any type of wall jboardsin sheetor' panel form, such as those made ofjwood fiber, asbestos, and the like, may be used. p

The'wall boards Hi and 14' are arranged in coplanar edgeto edge relationship upon the furring strips and-are secured theerto by clips {'5 which may "be arranged at suitable intervals along'the edges'of said boards at. the points of their'registratio'n wlththe furring strips. The clips 15' are .preferably' made ofa relatively stout resilientroun'd steel wire, although the wire may, of course, varycross section and may beformed of any suitable'material having sufficient strength and resilience. Each clip is formed of an intermediateor sharilrportion H5 which-is adapted, when the clip .is in use, to pass through the joint between the adjacent edges Lof adjoining wall boards, as best seeninFigs. 1 and4. The length.

of the shank [6 corresponds substantially with the thickness of the wall-boards with which it is used.

'At the rearward end of said shank-is formed an attaching hook which comprises an extension I? whichextends angularly or obliquely fromsaid shank and whichextension, whenthe clip is in use, isadaptedto rest-upon the upper side of the.

furring strip. Extending downwardly from the rear end of the extension I! and at right angles thereto is a hook portion l8 which is adapted to engage behind the furring strip so as to anchor the clip thereto. An offset detent t9 at the lower end of the portion P8 is adapted to engage under the furring strip so as to hold the hook in engagement therewith. The angle A formed between the shank l6 and the extension II, as seen in Fig. 1, is preferably about 45, although this may vary, it having been found that any angle between 30 and 70 is suitable. The angular disposition of the extension I! with respect to the shank 16 will vary somewhat with the width of the furring strip with which it is designed to be used.

At the front end of the shank I6 is a U-shaped loop, the plane of the loop being perpendicular to the shank. Said loop is formed of two substantially parallel legs, 20 and 2|, connected by the bight 22. The leg 20 is disposed in the same plane as the shank l6 and the extension II. The leg 2| is longer than the leg 20 so that when the clipis in use the loop thereof will rest flatly against the front face of the edge portion of one of the adjoiningwall boards While the free end of the leg 2| will span the joint between the boards and engage against the front face of the edge portion of the other board, as best seen in Figs. 1 and 4. The terminal portion 23 of the leg 2| is bent outwardly slightly so as to facilitate engagement of the board edge therewith.

It will be observed that the extension [I and the leg 20 of the lop extend from the same side of the shank It so that the bight 22 of the loop is directly opposite the furring-strip-engaging portion 18. That is to say, when the clip is in position, a line drawn through the portion 18 and the bight 22 of the loop will be substantially parallel with the shank I6. With this arrangement a clamping action is developed between the clip and the furring strip and wall board M, which serves to securely hold these parts in assembled relation.

The angular disposition of the portion l! of the clip with respect to the shank [6, that is to say the angle A, is important in order to insure a clamp-like grip of the clip with the furring member and wall board. While this angle can vary within a wide range, it has been found, as before indicated, that about 45 is satisfactory where the clip is used with a furring channel and wall board 1;" thick. With the channel and wall board of the dimensions indicated, and with the extension portion ll of the clip disposed at a 45 angle, as indicated, the bight 22 of the loop. [5 is directly opposite the portion I8 of the clip which engages behind the furring channel. However, this is not critical for the loop can be relatively longer or shorter than shown which, of course, will vary the relative position of the bight thereof with respect to the portion [8 of the hook of the clip. With a wider furring member and the same loop, a line drawn from the bight through the portion l 8 would not be parallel with the shank [6 of the clip. The dimensions of the clip must be such as to enable the loop portion thereof to snugly engage the wall board and the hook portion of the clip to snugly engage over and behind the furring member to produce the clamping action which will hold these parts in secure relation with each other. Channel furring strips and gypsum wall board are manufactured within fairly close dimensional tolerances and the clip may, therefore, be designed with the dimensions of these parts in mind. Where different widths of furring members and different thicknesses of wall board are employed, it will, of course, be necessary to vary the dimensions and details of the clip to accommodate the same to such furring members and wall boards, in order to obtain the best results. At the present time, however, 4" channels and gypsum wall board V thick are in general use so that clips designed with these dimensions in mind will function properly with the majority of structures. The clips are of such construction as to lend themselves to ready manufacture in various sizes and proportions and with a changed angle A in order to accommodate the clips to other sizes of furring members and wall boards.

In the structure illustrated in the drawings the furring strips are horizontally disposed and the wall boards vertically. It is, of course, understood that the clips are also usable where the furring strips are disposed vertically and the wall boards horizontally.

In use the wall boards are usually supplied with a fiinishing coat of plaster, which coat, of course, covers the exposed portions of the clips. Inasmuch as a finishing plaster coat is normally employed with the construction in question it is preferable to employ wall boards having an exposed surface of paper or of such character that a plaster coat will readily adhere thereto.

With clips of the construction described, wall boards may be readily and quickly attached to furring strips by workmen of very ordinary skill. By the use of such clips the boards and the furring strips will be effectively clamped together and the completed furred wall will be rigid and firm. Moreover the clips are so constructed as to permit of ready and economical manufacture.

While I have illustrated and described the preferred form of my invention, I do not wish to be limited thereto, but desire to avail myself of such modifications as come within the spirit and scope of the appended claims.

I claim:
