2 `Claims.

This invention relates to bar mats such as are used as reenforcements in connection with con crete road building. These mats are made of .a plurality 'of right-angularly crossed bars that are commonly interfastened by wire clips, and the Vpresent invention is particularly concerned with these clips and their use, one of the inventors ob- `jects being to provide clips which interfasten the bars of these mats so their right-angular relationship is positively maintained regardless of the rough handling which such structures frequently encounter; rOth'er objects may be inferredV from the following disclosure of aspeciiic example of a clip embodying the featuresof the present invention, and of a specific manner of using this'clip according to the teachings of this invention. s A.

Referring to the accompanying drawing:

Figure 1 shows two of the Vright angularly crossed bars of a bar mat and shows a top vie of the clip in use. I

Figure 2 is a side view of Figure 1.

Figure 3 is also a side View but Vdiiers in that it shows the clipin a released condition.

Figures 4 and 5 are cross-sectionsV respectively takenfrom the lines IV-IV and V-V in Figf ure 2. Y

The above drawing illustrates the clip as comprising a piece of spring wire in the 'form of an elongated looprof approximately rectangular out- A line, the respective end portions I and 2 of this Vpiece being arrangedso they canY be crossed at the side of one end of the loop, as at 3, and being respectively crimped, as at 4 andi, in opposite directions to form interlocking surfaces when so crossed. The portions 6 and 1 of the piece of wire forming the sides of the loop are looped at their centers, as at'8 and 9, in planes at rightangles to that of the first mentioned loop so as to provide a pair of alined bar-seats that open in similar directions, and the portions of this piece, IU and I I, forming the ends of this loop are looped at their centers in planes also at right-angles to that of this loopI so as to provide a pair of alined bar-seats which likewise open in. similar direc" Y tions, these directions being', however, opposite to that of the first mentioned pair so Vthat theY spective centers so as to spread the pair of barseats vformed by the looped portions 8V ,and 9.

In use, the clip is wrapped around two of the The sides of the loopY are' angled Vapart in the plane of the loop toward their re right-angularly crossed bars I2 and I3 and the endsofY the piece of Wire are crossed, as isV described above. I-lence the pairs of bar-seats are respectively engaging opposite sides of these bars'. Since the crimped portionsl 4 and 5 of these por- 5 tions are interlocked the latter cannot shift relav tive to one another, and the clip, therefore, positively maintains the right-angular relationship of the bars I2 and I3. Furthermore, the length and centralwidth of the clip are sufficient to -pro- 10 vide relatively long spans between the respective bar-seats, whereby distortion ofthe mat, ofy which the'bars I2 and. I 3 are a part, cannot permanently set the clip, while good structural bracing is obtained.

Now itis to be noted that the barV I 2 terminates adjacent the crossing portions of the two. Therefore, it is possible that very rough handling might longitudinally draw this bar through the clip to a suicient extent to clear the latter and, possibly, 20`

ing of this bars extreme end. This feature of 2g;V

the invention is particularly important when reenforcement mats are shipped on fiat cars with stakes thrust through their outer bars to retain the mats in position.

We' claim: so

1. A clip for interfastening right-angularly crossed bars, said clip comprising a piece of spring' wire in the formV of an elongated loop of Vapproxi-- mately rectangular outline, the respective end portions of said piece being arranged so they can 35 be crossed at the side of one end of said loop and being respectively crimped in opposite directions to form interlocking surfaces when so crossed, the portions of said piece forming the sides of said loop being looped at their centers in planes at 40 right angles to the plane of said loop so as to provide a pair of alined bar-seats that open in similar directions and the portions of said piece forming the ends of said loop being looped atV their centers in planes also at right-angles to the plane of said loop so as to provide a pair of alined bar-seats which likewise open in similar directions, said pairs of bar-seats respectively open'- ing in opposite directions so. that said clip can be wrapped around said crossed bars and said portions forming the sides of said loop angling apart in the plane of the latter towards their respective centers soY as to spread the first namedV pair of bar-seats.

2. The combination of right-angularly crossed 'y FFI-CE@ centers in planes at right-angles to the plane ofV said loop so as to provide a pair of alined barseats that open in similar directions and the portions of said piece forming the ends of said loop being looped at their centers in planes also at right-angles to the plane of said loop so as'to most adjacent thereto.

provide a pair of alined bar-seats which likewise open in similar directions, said pairs of bar-seats respectively opening in opposite directions and saidV clip being Wrapped around said crossed bars with said pairs of bar-seats respectively engaging opposite sides of said bars, said portions forming the sides of said loop angling apart in the plane of the latter toward their respective centers so as to spread the first named pair of bar-seats, and means on the end of said bar that terminates adjacent the crossing portions of said bars for preventing the same from being pulled longitudinally through the one of said bar-Seats ALAN E.
