MEANS FOR SECURING LATH FOR CHANNEL FURRING Filed April 7, 1942 2 Shets-Sheet 2 INVENTOR ANDERS C. Oms/v.

ATTORNEY Patented June 22, 1943 UNITED STATES PATENT OFFICE MEANS FOR SECURING LATH TO CHANNEL FURRING 8 Claims.

This application is a continuation-in-part of my co-pending application Serial No. 291,803, filed August 25, 1939.

This invention relates to an improved means for erecting lath on channel furring strips. More particularly, my invention relates to novel forms of clips for securing paper backed wire lath, expanded metal lath and other commercially available lath to channel furring.

Prior to my invention it has been customary to secure expanded metal lath, paper backed wire lath and wire-cloth to channel furring by wire tying the lath'to the furring. This procedure requires considerable skill and is time-consuming, thus' makingfthe installation of the lath costly.

The principal object of my invention is therefore concerned primarily with an improved means for installing and erecting paper backed wire lath, expanded metal lath, and otherplaster base materials on channel furring strips.

Another object of the invention is to provide novel forms of resilient clips adapted to secure Various commercial forms of lath, including wire lath, expanded metal lath, paper backed lath and perforated gypsum lath. to channel furring strips.

According to my invention, I` provide resilient clips which can be manually applied in rapid succession to secure the lath to the channel furring. the clips being designed so as to be capable of use somewhat in the fashion of snap-fasteners, one part of the clip being arranged to bear against the outer side of the lath and another part being arranged to extend into the furring channel and bear against the inner surface of the leg thereof against which the lath is placed,

thereby drawing the lath into and holding it in tight engagement with the outer surface of said leg of the channel.

. Further objects, features and advantages of the` invention will become apparent from the following detailed description and from the accompanying drawings, wherein several embodiments or modifications of the invention are set' Fig. 3 is a fragmentary perspective view from the side opposite that shown in Fig. 1, illustrating a partition construction having paper backed wire lath secured by the clips of Fig. 1 to the channel furring;

Referring t0 Figs. 1 to 3, the numeral I0 indicates paper backed metal lath secured to metal channel furring members II comprising a base portion l2 and leg portions I3 and I4. The channel furring may be employed in the construction of the ceiling, as indicated in Fig. 2, and also in the vertical walls or partitions as illustrated in Figs. 1 and 3. These furring members are of well known construction, and may vary in size and be spaced apart at various distances, according to the requirements of building codes. According to my invention, the lath is secured to these channel furring members by means of specially designed clips. One form of such clips is indicated generally by the numeral I5 in Figs. 1 to 3.

The clip I5 of Figs. 1 to 3 is more clearly depicted in Figs. 4 and 5. As will be seen from these gures, this form of clip is of general U-shape and comprises a base portion I 6, an outwardly extending resilient leg portion I'! and an outwardly extending arcuate and resiliently formed leg portion I9. The leg portion II has a resilient, reentrantly formed portion 20 which is adapted to spring inwardly, allowing the outwardly bent terminal portion 2l thereof to seat or rest and bear upon the leg I3 of the channel furring member II when the clip is forced into position over the channel, with the lath positioned between the outer face of the leg I3 of the furring and the inner face of the base portion I6 of the clip.

As illustrated in Fig. 4, it is preferred that the upper or outer ends of the resilient leg portion I'I and the reentrant portion 20 shall extend slightly above or beyond the upper or outer leg member I4 of the furring, as illustrated. The resiliently formed leg portion I9 of the clip may or may not extend to the same height as the leg portion I'I. It is obvious that the clip I5 may be so formed that it may be adapted for use with certain sizes of furring4 so that the number of sizes of the clips may be reduced in order to standardize the clips; that is, a clip I5 may be adapted to be used both with a 3A" and l channel, and another size of clip may be adaptedto be used with a 1 and 11/2 channel.

so that there will be marked resiliency between the various leg portions and-reentrant portions of the clip. The clip may be either galvanized by dipping or electro-plating or have other forms of rustproofing applied` thereto. The clip is so formed that the base .I6 willbe spaced from the .leg E13 of the furring channel l i a distance suicient toaccommodate the lath therebetween and permit the clip, after it has been snapped into proper position, as shown in full lines in Fig. 4, to Ldraw and hold tightly the lath against the outer .surface of the leg portion I3.

When the clip is applied, as indicatedcby the dotted linesfin Fig.r4. thereentrant portion 2G is forced outwardly and rides over the edge of the leg portion'I3 and then springs back inwardly as its free end passes by the leg portion I3, thus causing the portion i6 to snapintc placeV in ene gagement with the inner face of the leg i3. vSince the Vspring action of the clip is suchthat the reentrant portion 2l) engages and bears against the edge of the other leg I4, and since the portion I5 engagesthe lath located between it and the leg I3 of the furring channel, the resiliently formed leg I9 therefore rmly engages the base portion I2 of the furring channel and firmly-locks the clip in place on the furring channel, thereby securing the lath to the channel. Furthermore, as the clip is constructed of flat spring steel wire, the flattened portion of the base vIiand of the'reentrant portion 20 tends to keep the clip in an upright position. It is obvious therefore, when the clip is placed in posi tion over the paper backed wire'lath Il) of Figs. 1 to ,3 or the expanded metal lath .23 ofv Fig. 4, that the lath is rmly affixed to the furring channel where the clip is applied.

Another form of clip embodying myinvention is shown in .Figs'G to 10. This form of clip is made froma single ,piece of wire which may be veither hard drawn basic Wire or spring steel wire and .of say 13 to 15 gauge, depending upon the degree of strength desired in the clip.

This form of clip comprises essentially, a base portion 3I .having'open loops 32 and 33 at the ends thereof, and spaced armsformed integrally with the loops andextending substantially at a right angle to the general plane of the loops. The arms comprise portions 34, 35 return bent at 36, 3'I toprovideterminal portions 38, 39.

The wire is preferablyy twisted laterally inwardly adjacent the return bends 36, 31 so that the terminal portions 433, 39 will converge toward each other in the direction towards the base portion 3l, the ends 4U, 4I of the terminal portions being spaced apart a distance substantially less than the distance between the bends 3E, 3l.

`In formingthe'loops 32, 33, the wire is twisted,

near the open parts of the loops, so that the portions 42, 43 of the loops are oiset at a slight angle from the plane of the remaining or closed parts of the loops, and lie on the side of the loops opposite to that from which the arms 34, extend. The bends 44, 45 at the open ends of the loops thus form a slight bulge which functions to increase materially the spring action of the clip. This spring action enables the clip to be rapidly applied to a channel furring in the manner illustrated in Fig. 7. As will be seen from Fig. 7, slight pressing of the clip onto the furring in a direction at right angles to the plane of the legs of the channel causes the transversely extending arms 34, 35 with their converging terminal portions V`38, 3S to spread apart from their normal position and slide over the channel, and when the free end of one of the converging terminal portions has reached the plane of the inner surface of the leg 46 of the channel, the resiliency of the clip will restore the arms 3, 35 to normal position, thereby causing such terminal portion to snap into theV channel, with the end 4E offthe portion 39 seated and bearing against the Vinner surface of the leg 45. When the clip is thus properly positioned, the outer end 31 of the arm 35 bears against the outer free edge of the opposite leg 41 of the channel and the lower end-:40 of the other terminal portion 38 bears against the outer surface ofthe base 48 of the channel, thereby restraining any substantial rocking orV other movementof the clip. l

The length of the wire is such that when bent into the form of clip illustrated and described, the free outer ends 4Q, 4| of the wirevwillbe spaced from the portion 3| a distance suilicient to accommodate therebetween the thickness of the lath 53 to be fastened to the channel plus the thickness of the leg of the channel against which the lath is applied. An important feature, however, of this form of clip is that by reason of the resiliency imparted yby the outward bending of the portions 42,43 of loops 32, 33, the clip possesses sufficient resiliency to enable itV to function properly even though the spacing of the endsilll, M of the wire is somewhat less than the sum of the thickness of the channel and ofthe lath. Under such conditions it is necessary only to apply slightly more pressure to, or strike-a light sharp blow at, the portions 42, 43 in order to spring the clip into proper position. Such may Vbe the case, for example, where expanded metal lath is to be secured to the furring and adjacent sheets of the lath overlap one another'as shown in Figs. 6 and '7.

The clip of Fig. 8vmay also be employed for securing the commercial forms Vof perforated gypsum lath to cha-nnel furring. As shown `in Figs. 9 and 10, the lath 53a is positioned against the outer face of one of the legs of lthe furring in the usual manner. The clip is then inserted through any desired number of the perforations l5I of the lath which overlie such leg of the The resilient character of the clip shown in Figs. 6 to 10, provides also sufficient play so that while it effectively holds the lath to the channel furring, there is nevertheless suflicient freedom of movement so that when plaster has been ap plied to the lath, the tendency for the plaster layer to crack, as when subjected to the strain of slight movement of the structure, is greatly minimized.

It will be apparent from the foregoing that by my invention I have provided several forms of clips that can be made at very low cost and that can be rapidly applied in use for securing various commercial varieties of plastering base material, such as expanded metal lath, paper backed wire lath and gypsum lath to channel furring strips. Moreover, the clips are of such form and design as to be capable of being rapidly applied by unskilled workmen and without requiring the use of any special tools in order properly to position the clips in their correct functional relationship with the channel furring.
