. 3 Claims.

This invention relates to the attachment of furring bars or rods to support'channels andthe l,

like, preparatory to the mounting of plaster receiving material such asmetal lath to the furring members.

An object of the invention is to provide simple and elfective means for obtaining a strong and rigid mounting or connection between the furring and the support channels.

Another object is to provide means of the character and for the purpose indicated wherein the attachment means comprise simple structural elements so related as to attain inter-relationship of such means with thefurring and support members as will attain positive and rigid Xation of all of the -parts -with a minimum of effort, time and requiredskill incident to the association of such elements in their assembled form or relationship.

Another object of the invention is to sorelate the various parts of the assembledstructure that the forces serving to hold the members in assembled relationship will be directed along lines or in planes passing through the furring and sup.- porting channels as'distinguished from the olfsetting of such force as has been common in the art in devices heretofore provided for attaching furring rods and supporting members forthe furring rods. I r l vAnother object of the invention is to pro-vide attachment'means which are readily fabricated from various standard materials common on the market, and which will require a minimum of fabrication and forming for. adapting same t their intended use.

These and other objects are attained by the means described herein and disclosed in the ac- Fig. 5 is an edge view of the device shown in Fig. 4 in association with a nail orwedge member forming a detail of the invention. p

Fig. 6 is a sectional View through' a nail or Wedge member forming a detail of the invention.

(Cl. 'l2-e118) Fig. 7 is a perspective view of a modified form of clip forming a detail .of the invention.

In the vstructural arts, various devices have heretofore'been usedffor attaching metal lath and the like to suitable supporting structures. 5 Thesey supporting structures generally comprise metal bars generally referred to as furring members or bars which are disposed in parallelism and which are attached at intervals to supporting members. The lsupporting members generally 10 comprise U-shaped channel bars and are' disposed in parallelism and at right angletothe furring bars. `f

The supporting membersvorchannels are secured to the|.under faces of concrete ribs, joists and the like, in various manners and the particular arrangement for so attaching the supportingl channels does not constitute part of the present invention. By way of lreference to attachment of such supporting channels, attention is directed to such patents as `Venzie,' 2,055,759. In some instances the supporting channel members may be attached to metal I-beams, wherefore the invention is not to be understood as being restricted in its application to concrete structures, or any particular type of structure.

In the accompanying drawing, the supporting channel I0 is to be understood as being one of a number of similar channel members extending .in parallelism with one another and being supported or attached in a suitable manner to a suitable structure. .Y

The furring member ll is to be understood as being similar to a plurality of such members disposed in parallelism and intended to be related to the various support members such as I in. the manner in which the elements it) and Il are shown in Fig. 1. At each intersection of a support channel I8 and a furring channel Il, there is provided an attachment clip l2. Each 40 of the clips is of substantially U shape and accordingly comprises a base I3 and arms i4 and l5. Each of the arms is provided, adjacent its free end, with an' aperture or eye I6. The apertures so provided in the arms i4 and l5 of each 45 clip I2, are substantially aligned and are substantially equidistant from the base i3 of the clip. The clip is made of sheet metal and the width thereof is such that when a clip is passed about a furring member II and a supporting channel l0 so as to straddle them or to have the arms of the clip astride the structural elements the opposite edges such as Il and I8 of each of the arms, contact the members I0 and Il. The apertures I6 are spaced at such a distance from 55 the base I3 of the clip, that by inserting a wedge I9 through such apertures, the member IIJ will be drawn tightly and securely against the outer facev of the arm 2G of the support channel IIJ. As shown in. Fig. l, the lower face 2I of the Wedge lIll contacts the upper face of the arm 22 of the support channel I and the upper face 23 of the wedge. I9 contacts the upper Walls 2li of the openings I6 provided in thearms of the clip.

From the foregoing disclosure and explanation, it is obvious that the only tool required by a workman for assembling furring bars, supportbars, clips, and wedges, in the manner shown herein, is a hammer or an equivalent tool. As the wedgev is driven through the openings I6 in the clip, the furring bar Il is drawn into closer or more secure contact or relationship with the` support channel Il).

By reason of the angular disposition of the arms of the clip between and in contact upon the .outer .

faces

25 and 25 ofthe bases 2l and 28,

respectively, rof .Ll-shaped channel members lil and I I, the force applied to the assembly of parts is operative in planes extending parallel with and between the arms of the clip. In other words, the clamping force applied by meansV of the clip and the wedge is operative directly through the support member II] andfurring member I I, as distinguished' from the offset disposition of such force as occurs in such patents as Venzie aforesaid. l,

While the invention is not restricted in its application to the attachment together of chan-l nel iron furring and support bars, there are cer tain specic advantages and functional reactions incident to inherent characteristics of channel iron members, and which cooperate forattaining rigidity of attachment of the various parts, not attainable with other structural forms heretofore used in this art.v Particularly, the flexibility of the arms 2i! and 22, and 3U and 3I of therespec` tive channel irons, about their rrespective web or base portions 2l and 28, permits Iaccommodation of the contacting parts of the various elements` to one another, thus providing substantial bearing of the various elements upon one another. The flexible characteristics also enhance the grip or frictional contact that the elements exert on one another.l

In Fig. '7 is shown a Wire U-shaped` clip 'Illv comprising a base 1I, arms 'I2 and 53, and having eyes l@ and l formed at the free ends of the arms by looping or turning and twisting the material uponitself in anyv suitable manner. The

twisted portions of the clip arms are made sufficiently long to assure sufficient grip of the metal or wire portions so as to avoid opening of the eyes by reason of strain or pressure thatmaybe exerted thereon, incident to driving a Wedge I9 into the eyes for clamping ya pair of channel iron members together, in the fashion shown in' Figs. 1 and 3. lIf desired, the'said twisted portions TIS and 'Il' may be spot welded to prevent separation.` The. eyes are "to be `sojrelated to other parts of the assemblyas to attain the same results attained by use of clips, such as I2. f

What is claimed is: i 5 1.(The combination with a pair ofvchannel Virons extending at an angle to one another and having an arm of each in contact with an arm yof the other, of a U-shaped clip having its base in Contact upon a free arm of one of the channel irons, the arms of the clip being perforated at their free ends and at'a distance from the base thereof, approximatingthe combined widthof .saidv channel irons, the arms ofthe clip straddling the `channel irons, and a wedge Vextending throughy the apertures in said clip arms and' iric-r tionally securing the channel irons between the wedge and the base of the clip.

iso

y3. The combination of a pair*r of structuralv elements having contact upon one another and extending at an .angle to one another, a sheet metal U-shaped clip; having greater width than y thickness and having'itsarms astride both'said structural elements, theclip armsr being vperforated. at their free ends at a distance fromV the `clip base approximating the combined width of said structuralelements, the lateral edges of said clip arms contacting the structural elements, and awedgeextending through the apertures in said clip armsand frictionallysecuring the structural elements between the wedge and the base of the clip. 1 y' v .L y WILLIAM M.
