To all whom it may concern.

. Be it known that I, Alrilnjn V. Hmunairr, a citizen of the United States, residii'ig at Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Metal Reinforcements for Concrete Structures, of which the following is a specification.

This invention relates to the subject of metal reinttn-cen'ient for concrete and other cementitious bodies, and has particularly in view a reinforcement of this character that can be manufactured easily and economically, and which can be made up in a form to permit of convenient handling thereof.

To this end, the invention has for its object the construction of metal reinforcement for concrete in such a manner that ordinary wire or wire rods and sheet metal stamp ings may be utilized in its lllullllt lltfilll'fl, while at the same time producing a structure possessing sutlicicnt strength and rigid ity to l ult'il ordinary reinforcing requirements.

turther object of the invention is to provide a metal reinforcement made up oi the materials mentioned so that the same may be as ianbled at the factory and rolled up into bundles or coils and carried in such shape to the point of use and there cut all into the lengths or sections desired. i

With these and other objects in view which will 3.- adily appear to those l'amiliar with th art as the details of the invention are bcttcr understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more tally described. illustrated. and claimed.

'lhough susceptible of structural modili cation without departingfrom the scope ot' the invention. a preferred and practical embodiment thereof is shown in the accompanving drawings, in which---- l ic'urc l is a general view from the cde'c, illustrating the bundle .or roll torn] into which the material may be assembled at the tactory, and also showing how it may be drawn out iron: the roll or bundle to be out into the length or section desired. Fin. 2 is a perspective view ot the metal reinforcement. trout one side thercol'. Fig. I is a similar view troin the opposite side there of. Fig. l is transverse vsectional view longitudinally ol' one ol the transverse spacer bars on the line 1- -'l. of Fig. 1. Fig. 5 is an enlarged detail sectional View crosswise of one of the bars on the line 55 of Fig. 3. Figs. 6 and T are plan views of the two members of each spacer bar, namely of the stay strip and of the anchor strip.

Like references designate correspondii'ig parts in the several figures of the drawings.

The reinforcement material forming the subject matter of this application primarily comprises a. plurality of spaced longitudinal reinforcement. rods 1. and a plurality of transverse combined reinforcement and spacer bars 9, which rigidly connect and space apart the rods. This structure when made can be readily assembled in the form of a roll It, as indicated in Fig. l of the drawings, which roll of reinforcement material may be carried to the point of use, and the retutired length or section drawn out, as also indicated in Fig. 1, thus graitly improving the usual methods of handling and transporting metal reinforcement for concrete structures.

The longitudinal reintorceimuit rods 1 may consist of wire-rods of suitable strength and gage and arranged and spaced in parallel relation in any desired number according to the width of the material or fabric to be mauu't actured. The transverse bars 2 are likewise suitably spaced apart in parallel relation, the spacing tlierebetween beinc determined by the amount of rigidity which it is desired to give to the material. Each of these. bars 2 consists of two me1r bers, namely a stay strip 3, and an anchor strip t, both or" which are cut or stamped from sheet me at. 'lhe stay strip 2) is preferably formed with a longitudinal groove or otl'-set producing upon one side thereot' a longitudinal reinforcingrib 5, which gives added stillness and reinforce mom to the material. Each stay strip 3 is lurthenprovided in opposite edges thereot' with paired keeper notches t', eaclipair of which notches receive and interlock with one of the rods .1. and the said strip is also provided at its ends with narrowed terminal t'astenine tongues 7 adapted to be bent over the marginal rods .1 to fasten the strip thcreto. At its side edges. each stay strip 3 is provided with the edge securing flanges S which are :ulapted to be bent or folded-in over and upon the longitudinal edge portion of the anchor strip t, which is superimposed upon one side of the stay strip and extends over all the rods 1 between those at the margins of the material. The operw tion of folding'in and clenching the flanges 8 upon the anchor strip 4: not only brings the notches 6 into interlocking engagement with the rods, but also cl'inips the anchor strip over the rods producing rod-embin-1e ing eyes 9 therein. 7 are also clenched in place by the flanges 8 being unt thereo'ver.

Anysuitoble machinery and tools .my be employed in monuie luring and nee-e111 bling the moterial or structure above described.

I claim:

1. A reinlioroemeni: material consissl longitudnolly spaced .s'nenibeie, and. Ma verse bars connecting the, sznne, said. transrs each consisting of an anchor strip upon one side of lhe rods and hovk, interlocking engagement therewith, and. :1 stay elmip wronged upon the opposite meenee side of the members in parallel. relnfion to the anchor strip and having its longn jtndinal. edges engaged over Lheflongitndinal edges of the anchor strip,

2, A ieinforceinent' motel-1:1]. consisting of longitudinal spaced rods and o plnmlity oi transverse hers, each. of which. hers consists of an anchor strip arranged upon one 1 nee and hereunto nll'm in} signntui-e in the presence of two n'iin" en.
