To all whom, it may concern:

Be it known that l, Jonn J. Hammron, a: citizen of the United States, residing at St. Louis, in the State of Missouri, have invented new and useful Improvements. in Clips, of which the following is a specificatron.

The present invention relates to a new and; useful clip adaptedfor securing reinforcing rods to hold them in position durm the process of construction.

he primary object of the invention is to provide a simple, cheap and thoroughly efl'ective means for holding angularly arranged rods employed in concrete construction to properly sustain-the e during the process of molding.

Another object of the invention is to provide a clip for this purpose which is constructed of a single piece of wire that is centrally bowed in an angular direction to engage with one of the faces of the o posite sides of one of the reinforcin ro and which is continued longitudina y, in opposite directions, from the said bowed portion to contact with the. opposite sides, of

the second reinforcing rod, the longitudinal portions being bent at right angles and in opposite directions beneath the said second mentioned rod and having their ends bentato engage with-the sides of the rods opposite those contacted by the longitudinal portions of the clip which exten from the central bowed ortion thereof, and

whereby the rods w1ll be edectively, susthe improvement resides in the construction,

combination and arrangement of partsset forth in the following specification and falling within the scope of the appended claim.

In the drawing:

Fire 1 is a perspective view illustratinfii applicationof the improvement,

ig. 2 1s a top. plan view of the same,

Ti. 3 is a perspective view of the clip detaced and Fig. 4 1s a similar view of a modified form of the cli which may be employed upon t whicfi are round in cross section.

The cross bars used in concrete construction such as areindicated by the numerals l and 2 on the drawings must befastened together where they cross each other so as to befree from any movement one upon the other, as the movement of the said bars whlle the concrete is being poured or previous to the hardening or setting of the concrete wouldresult in an injury and perhaps rum to the finished work.

While various methods have been em ployed for holding the rods against displacement, in some instances, the said means have been found complicated, requiring time and laborin application and expense to manufacture and in other instances the do vices have been found to not eifectively perform their function.

My improved tie broadly indicated by the numeral '3 is formed of a single strand of wire and is consequently of a cheap con struction. The strand is centrally bent upon itself to provide a loop 4, the ends of which bein extended longitudinally to provide para lel legs 55. The loop 4: is arranged at an angle to the legs so that the legs are spaced one away from the other, but the side or arm portions of the loop preferably exert a tension toward each other and consequently tend to force the legs 5 also. toward each other. The loop 4 is arranged upon the bar 1 at the point of crossing thereof with the bar 2 andis adapted to be'engaged with both the outer, face and with the sides of the. said bar 1, while 'oneof the legs 5 contacts with one of the sides of the bar 2 and the other leg 5 contacts with the opposite side of the said bar 2. Of course, the respective legs 5 en age with the opposlte .respective sides of t e bar 2 which are extended in opposite directions from the sides of the bar 1. The legs 5 have their ends bent at a right angle in a line with the sides of the bar 5 as indicated by the numeral (if and are from thence bent to provide what will term arms and which are indicated by the numerals 7, the said arms extending transversely across the lower face of the bar 2 in opposite directions. with relation to each other and the ends of these arms are TOW bent upwardly or in the direction of the the bar 2 opposite that engaged by their are upon crossed rods which are.

round in cross section and likewise the arms '7 at the ends of the legs 5 are rounded or curved-in an opposite direction to that of the loop 4. I

With an article constructed as hereinbefore illustrated and described it will be noted that the vclip may be readily positioned upon the bars as either of the legs may be swung after the looped portion of said clip is arranged upon the. bar 1, to bring its angular end or arm portion .7 to engage with the face of the bar 2 opposite the face of the bar 1 engaged by the loop, and the angular end 8 of what I have termed the arms 7 is adapted to assist the loop l in forcing the legs 5 in contact with the opposite sides ot the bar 2.

Having thus described the invention, what I claimis:

In combination with two right angularly" disposed bars for concrete reinforcement, of

' I a clip for securing such bars together, comprising a metal rod centrally bent outward of itself to provide a loop, the connecting members for the arms of the loop being disposed at an angle, the said loop designed to straddle the rods at the crossing thereof to permit of the said connecting member of the loop resting upon the upper bar and the arms of the loop contacting with the sides of both of the bars, said rod, from the arms of the said loop, being continued longitudinally in opposite directions to rest against the opposite sides of the lower bar, and having their ends bent downwardly of the said sides of the said lower bar and extended transversely beneath the said bar and then bent upwardly to engage with the opposite sides of the said lower bar.

In testimony whereof I afiix my signature in presence of two witnesses.
