This; invention apprtai ns to eme ge strucltuiesfandi moreparticularly to the'reenforcen ent its sues: dossiersamaur esw p p Oneofthe primary objects of' ln-y invention-is theprovision of-novel- "means for connecting together the reenforcing rods of concrete structure, said means being so constructed as to permit the expeditious placing thereof in position in engagement with the rods and to hold the rods against accidental movement.

Anotherprime object of my invention is the provision of novel clips for connecting the reenforcing rods of concrete structures together, the clips being each struck from a single'blank of sheet metal, and each including a body portion for engaging about one rod and bendable fingers for engaging about and holdingthe other rod.

A further object of my invention is the provision of clips for connecting the reenforcing rods together, which can be readily used with varied characters of rods, such as smooth round rods, ribbed round rods, or rods of square shape in cross section. I

A still further object of my invention is the provision of novel clips for connecting the rods 1 of reenforcing concrete together, which will be durable and efficient in use, one that will be simple and easy to manufacture, and one which can 3 be placedupon the market at areasonable cost.

. With these and other "objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawing, in which draWing:-

Figure 10 is a horizontal section taken on the line lO-"lQfof Figure 9 showingthe clipin top Figurell is a detaihperspective view of the clip utilized in connection with reenforcing rods of square shape in cross section.

Referring to the drawing in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A. generally indicates one of my improved clips for holding a pair of crossed rods 20 and 21 together, the rods being adapted to be imbedded in a suitable concrete structure 22 for reenforcing the same. The rods 20 and 21 can be of any desiredcharacter, but in Figures 1 to i 7 inclusive I have shown smooth round reenforcing rods.

As clearly shown in Figure 5 of the drawing each of the clips A is struck from a single blank of sheet metal and each include a flat body portion 25' having enlarged terminals 26 and 27, which are bifurcated asat 28 to provide bend-, ablespaced parallel fingers 29. v i

The body portion 25 is adapted to be folded on a central transverse line so as to bring the enlarged terminals 26 and 2''! into spaced parallel relation, the folding of the blank providing a clip substantially U-shaped in sideelevation.

In use of the clip, the same is slipped over the horizontal rod 21, as clearly shown in Figure 6 of the drawing, with the enlarged . terminals 26 and 27 extending above and below the horizontal rod, with the fingers 26 and 2'7 grasping the vertical rod 20 above and below the horizontal rod 21. The bendable fingers 29 are then twisted at right angles, as at 30, as clearly shown in Figure 6 of the drawing andbent around the vertical rod as clearly shown in Figure '7 of the drawing. This forms an efiicient means for connecting the crossed vertical and horizontal reenforcing rods of the concrete structure together andthe clip is easily applied to the rod without undue difficulty on the part of the worker.

In Figure 8 of the drawing I have shown one of the improved clips in use for holding a pair of reenforcing rods 31 and 32 of the ribbed type as shown in Figures 9 to 11 inclusive of the shape in cross section can be slightly modified and as shown the same include a substantially U-shaped body 35 having spaced parallel upper and lower leg portions 36 and 37. The upper and lower leg portions 36 and 37 are bifurcated to provide bendable fingers 38. In this form the body portion 35 is slipped over the horizontal reenforcing rod 39 with the bendable fingers 38 engaging the opposite sides of the vertical reenforcing rod 40. The terminals of the fingers are then bent at right angles over the vertical rod as indicated by the reference character 41 in Figure 10 of the drawing.

Changes in details may be made without departing from the spirit or the scope of this invention, but:

What I claim as new is:

As a new article of manufacture, a clip for connecting reenforcing rods together comprising a bendable metal body formed from a blank sheet drawing. The clip for use-with rods of square of material, having a shank adapted to snugly fit around one reenforcing wire and conform to the contour of the reenforcing wire, the ends of the body being cut-out to provide a curved inner wall at the inner end of the cut-out portions adapted to conform to the contour of a cross wire and to permit the cross wire fitting within the cut-out portions to abut against in contacting relation with the wire mounted within the shank, the ends of the body having an upperand a lower pair of bendable fingers which.

are twisted at their junction with the shank and are bent to have their fiat inner faces snugly conform to the contour of the rod fitted within said cut-out portions whereby the cross rods within the shank and within the cut-out portions may be firmly locked in contacting relation, the clip occupying a minimum area for tying a plurality of rods together.
