CDNSTRUCTIQN CLIP Morris Liefr, Newark, N. 1., assignor, by mesne assignments, to The Patent and Licensing Corporation, New York, N. Y., a corporation of Massachusetts Application October 15, 1952, Serial No. 314,788

2 Claims. (CI. 24-73) This invention is a construction clip, particularly for anchoring adjacent edges of building slabs, wallboard and the like to a supporting beam, and to each other.

The clip of this invention comprises a substantially U-shaped member which snaps into locking engagement over the head of a bulb T or over the head of any similar supporting beam. This anchors the clip to the beam. The clip further comprises an anchor plate se cured across the top or outside of the bight portion of the clip, this anchor plate extending laterally at substantially right angles to the legs of the clip for a substantial distance and is adapted to engage with and be anchored in the adjacent edges of the building slab, wallboard, plasterboard or the like. This anchor plate may be provided with terminal flanges, extending at substantially right angles to the plate and preferably in the same direction as the legs of the U-shaped member. These flanges, however, may be omitted.

The structure and use of the clip will be described in more detail in connection with the accompanying drawings wherein:

Fig. 1 is a side elevation of the construction clip of the present invention.

Fig. 2 is an end elevation of the clip.

Fig. 3 is a perspective view of the clip.

Fig. 4 is a side elevation, with parts in section, showing the clip in use.

Figs. 5 and 6 are views similar to Fig. 4, showing the clip in use in thicker material.

Referring now to these drawings, the clip comprises a substantially U-shaped stirrup member indicated generally at 2, made of sheet metal. The bight of this member is substantially flat, as at 4, and is provided with integral, downwardly extending laterally resilient legs 6.

The stirrup 2 is provided with inwardly extending resilient lugs 8, struck from the metal of the legs 6 and extending toward the bight portion 4 of the clip.

A substantially flat anchor plate 9 made of sheet metal is secured at about its mid portion to the top or outside of the flattened portion 4 as by the rivet 10 or by welding, or by a screw, bolt or the like.

This anchor plate 9 extends for a substantial distance laterally on each side of the legs 6. It is preferably provided with terminal flanges 12 approximately perpendicular to the plate 9 and preferably extending downwardly in the same direction as the legs 6. For some uses, these flanges may be omitted.

In operation, in order to secure the adjacent ends of two pieces of building slab or wallboard or the like 14 2,780,850 Patented Feb. 12, 1857 to a beam or supporting member 16 provided with an enlarged head portion 18, the clip 2 is pushed downwardly over the head 18, the legs 6 springing outwardly and the lugs 8 also being pressed outwardly until the resilient lugs 8 have sprung inwardly and snapped under the head 18, thereby anchoring the clip to the beam 16.

The anchor plate 9 may rest on the top of the building slab or wallboard 14, as in Fig. 4. Where the slab or wallboard is thicker, as in Figs. 4 and 5, the anchor plate may be bent, as it is hammered into place, this bending or distortion of the plate causing the clip to press downwardly on the slabs or wallboards with a strong holding effect.

Where flanges such as 12 are used, such flanges become embedded in the slab or wallboard, as shown in Figs. 4, 5 and 6.

Thert has thus been provided in a single article of manufacture, a construction clip, which may be snapped over the enlarged head of a bulb T or similar support, the clip anchoring itself automatically to the beam when the inwardly extending lugs 8 snap under the head of the beam. The anchor plate bears against the slab or wallboard, thereby securing the slab or wallboard to the bulb T and to each other.

While the invention has been described in some detail, it should be understood that the invention is not limited to the precise details shown, but may be carried out in other ways, as falling within the scope of the claim.

I claim as my invention:

1. A clip of the character described for anchorage to a beam having a relatively thin web terminating in an upper enlarged head substantially wider than said thin web, comprising an inverted substantially U-shaped member, the legs of which are substantially parallel and are spaced apart a distance slightly greater than the width of the enlarged head of said beam and are adapted to engage over and to embrace said enlarged head, the legs of said U-shaped member having inwardly extending resilient lugs adapted to snap over said enlarged head and to engage said thin web under said enlarged head between said legs, and an anchor plat-e secured to the top of the bight of said inverted U-shaped member and extending for a substantial distance laterally on both sides of said bight portion and having terminal flanges substantially perpendicular to the anchor plate and extending in the same direction as the legs of said U-shaped memher and adapted to be driven into board held in place by said clip.

2. The combination as claimed in claim 1 wherein said anchor plate has a central depression and is secured to said U-shaped member at said central depression.
