COMBINATION TIE AND GAGE MEMBER roe REINFORCED CONCRETE CONSTRUCTION.

Application filed 1111917, 1911, Serial No. 638,839, Renewed July 12, 1916.

To all whom it may concern:

Be it known that I, WILLIAM B. HOUGII, a citizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvements in Combination Tie and Gage Members for Reinforced Concrete Con-- struction, of which the following is a speci fication.

It is usual to reinforce concrete floors and similar structures by embedding metallic bars therein, these bars being ordinarily .located in the lower portion of the floor.

This invention relates to improvements in' means for spacing such bars apart at regular or desired intervals, for spacing them at a uniform distance from the ceiling or lower surface of the floor slab, and for securing the bars against displacement.

In the accompanying dawings, Figure l is a fragmental section of a concrete floor, the reinforcing bars being spaced and secured in place by means embodying the features of my invention. Fig. 2 is a sectional view taken at right angles to that of Fig. 1. Fig. 3 is a fragmental perspective view of one of the combination tie and gage members. Fig. 4 is a fragmental top plan view of the combination tie and gage member. ig. 5 is a side elevationof said member. Fig. 6 is an elevational view taken from the side opposite to that shown in Fig. 5.

In the drawings A represents the formwork upon which the floor is to be cast, the concrete being indicated by the dotted lines I3, and the reinforcing bars by C. Said bars are spaced apart from one another at a suitable distance, are supported at the desired distance from the form-work A, and are secured in place by means comprising a suitable number of devices each of which de-. vices comprises a longitudinal member formed of wire and bent at intervals to form gages or legs 2. In order to secure the bars C in place and to provide additional strength for the support of said bars, I provide at each gage 2 means consisting of a separate or special piece of wire bent to form a leg 3, which may, if desired, be similar in form to the leg 2. The said special length of Wire is also bent around the leg 2, as at 4, the end 5 of the wire being brought up at an angle, as indicated in Fig. 6. The said special wire is also bent as at 6, and the end 7 inclined upwardly. The ends 5 and 7 constitute arms cured to the longitudinal wire 1 Specification of Letters Patent. P t t d 27, 1913;

between which a reinforcing bar C may be laid, which arms may be bent to embrace the bar, as indicated in Figs. 1 and 2. The bends 4 and 6 look the leg 3 and the arms 5 and? in proper relation to the longitudinal wire 1. It will, however, be understood that bends of other forms may be employed, and that the special wire by means of which the barembra-cing arms are provided may be sein any suitable manner.

The bar-engaging means is connected to the V-shape leg 2 at 4 and 6, and thus serves to tie together the two side portions of said leg and prevent said side-portions spreading apart. The bar C is thus effectively sup ported at the proper distance from the framework A.

By forming the tying means from a special element I obviate the necessity of weakening the longitudinal member by cutting or otherwise forming arms from such longitudinal member.

I claim as my, invention:

1. As an article of manufacture, a combination tie and gage device comprising a longitudinal member having a series of downwardly extending bends therein disposed atintervals along its length, each bend being adapted to underlie and support a transverse reinforcing bar, said bends constituting legs or gages, and a plurality of relatively short wires, each having its central portion twisted about each of the opposite sides of one of said gages, the ends of each of said shorter wires being free, and each of said ends extending from its side of the gage around to the opposite side of the reinforcing bar and being adapted to be bent upwardly around said bar for securing the latter to the gage.

2. As an article of manufacture, a combi nation tie and gage device consisting of a longitudinal wire having a series of-bends member and secured thereto, each of said members being bent to provide a supporting leg or gage, the end portions of each of said flexible members constituting arms adapted to be bent into embracing relation to a reinforcing bar, said longitudinal member being bent to provide supporting legs or gages located adjacent to the other gages.

4:. A combined tie and gage member for concrete construction having a longitudinal member, a plurality of Wires arranged at intervals along the longitudinal member and five cents each,

twisted around said longitudinal member, each of said Wires being bent to provide a supporting leg or gage the end portions of each of said Wires constituting arms adapted to embrace a reinforcing bar.

In testimony whereof I hereunto a'lhx my signature in the presence of two Witnesses.
