HOLDER FOB CONCRETE1REINFORCING.

v Specification of Letters Patent.

Patented Nov. 9, 1909.

Application filed .Tannary 25, 1909. Serial No. 474,055.

To all whom it may concern:

Be it known that I, JOHN WESLEY REED, a citizen of the United States, and a resident of Hammond, in the county of Lake and State of Indiana, have invented a new and Improved Holder for Concrete-Reinforcing, of which the following is a full, clear, and exact description.

The invention is an improvement in holdore for concrete reinforcing, such reinforcing, in the nature of bars, as is positioned along the walls or floors of wooden forms during the course of erection.

In carrying-out the invention I construct the holder of a single piece of wire, the

same being bent to form an eye to embrace the reinforcing bar, with the end portions of the wire extended from the eye to ro-- Vide nail prongs, the prongs being 0 set intermediate their length to provide striking faces, said nail prongs arranged to open the eye when spread apart, whereby the eyemay be sprung over the bar.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views. I

Figure 1 is a, fragmentary view of .a wooden form and reinforcing bar: with the bar held in position by my improved holders; Fig. 2 is a vertical section through a form, illustrating the application of my improved holders to hold the reinforcing bars in place, and Fig. 3 is a face view of the preferred form of the holder.

The holder, as shown in Fig. 3, is con-' structed of a single piece of wire bent in- I termediate its length to form an eye 10 to embrace the reinforcing bar, the end portions of the wire being extended from the eye to :form nail prongs 11. These prongs have sharpened extremities and are outwa'rdly' offset intermediate their length to provide striking heads or faces 12', by which the driving of the members into the wooden form may be facilitated. The holders described, as manufactured, have the nail prongs l1 sprung apart in order that the eye. 10 maybe open to permit of its being passed over the reinforcing bar. These bars 13, as shown in: Figs. .1 and 2, are arranged along-the walls of wooden forms 14, the bars being spaced from the inner faces of the walls, as is the usual practice.

In applying theholder as shownin Fig. 3 to the bar, the eye of the holder is passed over the body of the bar and the nail ,prongs forced togethercwith a pair of pliers or other suitable tool, closing the eye to embrace the bar, as shown in Fig. 1. The nail prongs are then driven into the reinforcing, either by striking the eye 10 or the offset or striking faces 12 of the prongs. The holders are applied at such intervals as are necessary to hold the bars agalnst displacement during the filling in of the concrete.

In testimony whereof I have signed my' name to this specification in the presence of two subscribing witnesses.
