Serial No. 663395.

placement (and the con'sequent injury' or ruin of the finished work) while the concrete is being poured or otherwise manipulated previous to setting or hardening.

The general object of the inventiong isto provide improved means for this purpose especially adapted to the securing together of reinforcing bars which cross each 'other at right or other angles. 4

A further object is to provide such secur- 'ng means of such a character that the concrete worker may make them himself at the 'work to suit general or particular forms.

A further object is to provide securing means with improved means for supportin the securedtogether bars at a suitable heght from the bottom of the mold.

With these and other objects in View, the invention consists in a clip or clamp of the improved form, and of the material hereinafter fully described and afterward specifically claimed.

In the accompanying drawings, which illustrate preferred embodiments of the inven'tion, Figure 1 repfesents a plan view of a pair of reinforcing bars crossing each other and Secured together by the improved clamp; Fig. 2 represents a vertical seetional view of a sidewalk or other horizontal concrete Construction havingreinforcing rods such as shown in Fig. 1 n `position therein and positioned and secured by the improved clamp and supports; Fig. 3 represents in perspective the improved combined clamp and support, detached; Fig. 4: represents in perspective View, the clamp and support in' position on a pair of reinforcing bars such as shown in Figs. 1 and 2; Fig. 5 represents in perspective view the improved clip or clamp without the supporting leg; and Fig. 6 represents a vertical sectional view through an upright concreteconstruction, such as a wall or'the'like, with the clamp or clip of Fig. 5 therein securing reinforc-` ing bars together.

Like reference characters markthe same parts wherever they appear in the drawings.

Referring specifically to Figs. 1 to 4, in'- clusive of the drawings 'A and B' indicatereinforcing bars which lie horizont-any and' cross each other' in contact and which are especially intended in this position as reinforcements for horizontal concrete Constructions, such' as floors, and the like, as at C.

2 to engage over the lower bar B. From ths hook the wire is bent in a direction subv stantially 'Parallel with the upper bar a, point 3 where it' is bent downward and again, at the point 4:, back upon itself forming a leg or support 5. At 6 ,the'wire is again bent'horizontally as at .7 and 'thence upward and back forming a loop, to engagej over the upper' bar A. From is 'Ioop the w re is carried along, as at 9, substantially parallel with the bar A, under *and past the rod B, and at its opposite end's bent into the form of`a hook 10 to upper bar A. u When in position, as shown in Fig.2, the two hooks 2` and 10 being engaged over the upper bar A, the stretch 9 passing under the bar B holds it up' against the upper bar A, and the legs 5, of which there is oneat each crossing of the bars A and B, firml y support the Secured together bars A and B in the mold so that the concrete may be poured therein without displacing or disar-' ranging the reinforcements.

In Figs. 5 and 6 the 'Construction' 'is shown without the' leg 5, the latter being unnecessary in vertical constructions, as at D, where' one of the bars, as'A', is vertical and the other as B' crosses in contact with it, and is usually horizontal. In this form the hook 2' eng'ages the bar B' and from this point the wire extends, as at 7 in' a substantially vertical direction, until turned horizontally and 'bent' to 'form the loop 8' to engage around the vertical bar A'. From the loop 8' the wire extends, in subengage over the `stntially horizontal direction, as at 9',

My improved clip or clamp. and support is indicated as a whole atl and is preferably' formed of a single piece `of flexible stiff' wire' being bent at one end to form a hopk crossing the bar B' in contact there'wth and bindn'g' it against the bar Agam termimiting in a 'horizontal loop engaging 'around the bar A'.

The Construction and operation of the foregoing description, in connection with the accompanying drawing and it will be obvious to those skilled in the art of concrete reinforcement that slight variations s .V may be made in the construction of the parts without departing from the spirit and scope 'of the invention as hereinafter claimed.

Having thus fully described the invention, *what is claimed as new is f bind it to the first named bar, a loop at the other end of said Stretch engaging around the' first named bar, a Stretch from the loop substantially arallel with the 'first named' Stretch to .the second bar, and a hook at'the 'end of :the last 'named Stretch engagng around the second bar, the last named bent outward substantially at a right the invention will be readily comprehended from angle and back upon itself, intermediate its ends, to form a supporting leg. 2. The hereindescribed reinforcement for fioors or other horizontal concrete constructions, comprsing two horizontal bars crossing and in contact with each other and a combined clamp and support for said bars comprising a wire bent at one end into a loop and embracig the lower bar and carri'ed substantially horzontally a short distance, thence bent downward and doubled back upon itself forming a leg, thence again carried a short distance substantially horizontally and formed into a loop embracing the' upper bar, thence carried substantially horizontally in the opposite direction across under in contact with the lower bar and beyond said lower bar, and terminating in a loop embracing the upper bar.

In testimony whereo' I afix my signature in presence of two witnesses.
