SECURING DEVICE Cooper 0. Drury, Dallas, Tex. Application November 2, 1946, Serial No. 707,431

This invention relates to new and useful im- 5 Claims. (01. 189-35) provements in securing devices, and more particularly to clips for securely aflixing insulating material and the like to stripsteel framing members.

In building construction, it is becoming more common'to utilize strip steel framing members in the form ofan I-beam having a nailin groove formed therein, of the type commonly known as .Stran-Steel. These framin members may .take the formofstuds, joists, ribs, purlins, trimmers and the like, and other building materials can be nailed directly to the framing members, the nail being deformed and clinched as it is driven into a nailing groove provided in the members. Due to the fact that the framing members are formed of steel, it has been diflicult to secure insulating material and the like between the steel frame members in the usual manner.

It is, therefore, one object of this invention to provide means for securely affixing insulating material and the like between steel framing members.

A particular object of the invention is to provide resilient clip means for attaching the tabs of strips or bats of insulating materials to steel frame members for securely maintaining such insulating materials in proper insulating position.

A further object of the invention is to provide clip means of the character described for releasably securing the insulating material to the steel framing members, whereby alterations or adjustments in the installation may be made without damaging either the frame member or the insulating material.

Still another object of the invention is to provide means for securely afiixing insulating material and the like in place between steel framing members in such a manner that the installa tion does not interfere with the normal use of such framing members.

An important object of the invention is to provide resilient clip means for securely affixing insulating material to steel framing members which is arranged to hold the tabs on the insulating material against displacement by so clipping the tabs to the framing member that force tending to displace or free the tabs from the clip means increases the frictional gripping of the clip means.

Additional objects and advantages of the invention will be readily apparent from the reading of the following description of a device Gen- 2 structed in accordance with the invention, and reference to the accompanying drawings thereof, wherein:

Figure 1 is a fragmentary view, in elevation, of a section of a building wall illustrating the manner in which the securing means is aflixed to the steel framing members.

Figure'Z is an enlarged transverse sectional view of the framing member showing the clip in place thereon,

Figure 3 is a side elevation of the clip constructed in accordance with the invention, and

Figure 4 is a plan view ofthe clip.

In the drawings, the numeral l0 desigates strip steel framing members of the type commonly known as Stran-Steel, which are formed of two substantially U-shaped or channel sections joined back to back to provide the substantially I-shaped' framing members having a longitudinally extending nailing groove H between said sections. The web of the framing member is provided with one or more longitu dinally extending convolutions Illa, whereby nails or the like driven into the groove II will be deformed to conform to the shape of the convolutions in the web and thus will be securely held in place in the groove. The framing members are spaced apart in the customary manner to provide a support for the walls or otherportions of a building, and wall board l2 or other building material is secured to the framing members by means of nails l3 or the like driven through the wall board and into the nailing grooves H in said framing members. I

In building construction, it is frequently desirable that heat insulating or sound reducing material be interposed between the outer layers of wall board which are secured 'to'the framing members. In order to properly support the insulating or sound reducing material'in position between the framing members ill, some means must be provided for securing such material to the framing members. The customary insulating material consists of an elongate strip or bat of wool-like material l4 enclosed in an envelope l5of suitable chemically treated paper or the like which is provided with=longitudinally extending flange-like tabs l6 at opposite edges of one of the larger surfaces of the envelope. In the usual installation, these elongate marginal tabs are nailed or tacked to wood framing members to securely hold the insulating material in place between the framing members.

In making. installation of the insulating material between the steel framing members, how- 3 ever, some other means must be provided for securing the tabs to the framing members.

A spring clip 20 formed from a single elongate piece of metal, perferably spring steel or the like, is adapted to slide over one half of the flange of the I-shaped framing member In to releasably clamp the tab l6 of the insulating material to the framing member. The clip is formed by bendingan elongate strip ofspring metal upon itself to provide an open loop 2 and an elongate outer leg 22 and a shorter inner arm 23. The end of the inner arm 23 is provided with a curved tip or finger 24 which is turned outwardly away from the outer leg 22 of the clip to facilitateentry of the flange of the framing member between the arm and the leg of the clip. The inner arm is preferably bent toward thetouterleg 22 until the outer curved portion thereof is in close proximity or contact with the outer arm, whereby the clip will securely clamp any. material inserted between the inner endofthe'arm and the leg Theextreme*outerend-of the'le'g 22 is provided with an inwardly turned Ca-lldh' Offt Hand-this 'ioo't' is' adapted toengage in the nailgroovell of the I-shapediraming member I 0 to prevent displacement of the =-c1ip from the flange of the framing member, whereby the clip and the insulating material clamped thereby to the framing member are securely held in position on said framing member.

The length of theinner' arm'23 is such that it contacts the inner surface of the outer leg 22 at a point short of the foot 25 on said leg, whereby said am will terminate short ofthe web of the framingmemberand the tab 16 on theinsu'lating material may be bent inwardly, in the manner illustrated' in Figure fl, to lie parallel to the inner s'id'e'=of--the flangeof the framing member and "be clamped thereagainst by said arm when the clip member is slipped onto said framing member.

Since the clip is restrained against displacement iromthe framing member by the engagement of the foot 25 within the nailing slot or 'g-roove l I'in thetrami-ngmember, it will be seen ward theweb of the framing member and then around the finger 24 and outwardly away from the -web of the framing member. Thus, the clip isarranged tollold the tab on-the insulating material against 'displacement'by so clipping :the tab to' the framing member that force tending .to *displace or "free thetab from the clip' increases the-frictionalgripping or the clip.

' "The clips are appliedat spaced intervals longi- 'tudinally of the "framing members, the spacing being such that the insulating material will be securely held improper insulating positionbut utiliaing a minimum of clips.

Gbv-iously, the clip may be "readily removed from engagement with the framing member by lifting thelioot ca tch 25irom within the nailing groove :and sliding the clip outwardly 701T the flange; Thus, the installation may be altered or adjusted without damaging eitherthe framing member or the insulating material, 'andthe :elip members may berepeatedly used for clippmgor clamping the insulating material to the framing members.

Since the clips are formed of flat metal strips, they lie very close against the flange of the framing member and do not materially interfere with the normal use of the framing members. Also, the clips will not prevent the entry of nails into the nailing groove in the framing member.

Furthermore, the clips are resilient and may be readily installed without special machinery, without drilling additional holes in the framing members and without interfering with the normal use of such framing members. Also, the insulating material is. securely and positively held in proper insulatingposition between the framing members.

Theforegoing description oi the invention is explanatory'only, and changes in the details of the construction illustrated may be made by those skilled in the art, within the scope of the appended claims, without departing from the spirit of the invention.
