METALLIC- s'riwc'runn.

To all'whom it may concern.

- Be it known that I, lVlAtmIcn LAOHMAN, a citizen of the United States, and a resident of New York, in the county .of'Ncw York and State of New York,'have' invented a certain new and useful Metallic Structure,

'of which the following is a specification.

*My invention relates to metallic structures or fabrics such as used for reinforcement I poses and jao for concrete work, lathin and other purcomprising memdmrs crossing one another and secured together at their intersections by suitable fastenin 's.

The invention is particu arly useful in connection with metallic structures. or fabrics whichare to be used for reinforcement for concrete work, such as for joining sections of metallic fabric together or for fastening the members of the fabric or structure at their points of intersection.-

One of the objects of the invention is to operation can be quickly .and securely done by the workmen atthe place it is desired to usethe fabric. a r i Another object is to provide the members of a metallic structure with means-whereby they can be readily and quickly secured together, thesemeans being permanently located on one ofthe members "when detached, whereby they can be shipped in bundles andcan be'quickly secured-attheir intersecting points when desiredto form the fabric OIjStIllCtUlG and proper'spacing attained.

A s'till further object is to provide a bar or wire with clips welded to it at intervals apart'by means of which the bar or wire may be secured to a companion member. whereby reinforcements for use in any shaped form may be attained.

o these ends the invention consists in the improved metal fabric or structure hereinafter described and claimed.

The invention also consists in the improved manner of joining the sections of metal fabric and further consists in the improved manner offastening the members of a metallic structure to each other.

The invention consists still further in providing-tension .or similar bars or wires with Specification of Letters Patent. Patented lffll. 17, 1914. Application filed January 26, 1909. Serial No.

clips elcctricallywelded thereto and provided with ears whereby they may be secured to a' connecting bar or other companion member. i

In the accompanying drawings Figure 1 enlarged section through a tension wire and clip before welding and illustrates the preferred-method of securing the clip to the wire. F ig. 6 is a similar view after weld ing. Fig. 7 is a developed plan of the preferred formof cl ip.- Fig. 8 illustrates the manner of forming the reinforcement for a concrete column.

In the various figures of the drawings, one'of the members or tension wires of the fabricor structure is indicated at 1, while 2 indicates the distributing wires or ion members.

It "isth'e usual practice in metal fabric used for concrete reinforcen'ient to form the tension wire as a round wire or rod and the distributing wire fiat and I will herein show themes such, but I do notlimit myself to companthe same as other suitable forms might be p of my invention. Also where the term "'w1re-1s employed it will be understood thatieither a w1re rod, bar or other similar or equivalent member is meant.

employed without departing from the spirit 3 indicates clips which in the preferred form are flat strips ofmetal' and electrically welded to the surface of the tension wires 1. This electric welding of the clips and tension'wires might be effected in any suitable way, such as for instance, providing a point or projection 4 on the clip 3 as shown in Fig. 5, passing anel'ectric current through a v the wire and .clip and pressing them together in the line of the projection, the weld when finished being shown in Fig. (3. The point at which the clips are preferably welded to the tension wires is indicated at 5'. r

In the drawing Fig. 1, I'show two sections of metal fabric, the intersecting tension wires 1 and distributing wires abeing secured to each other at their inter ec- GMSIfi of the clips 3 pass' thi'ough v Hugs-18, in the connecting bars and are turned v over againsfi'thelopposite side of'the. bars 7, thusfholdin'g. the tension wiresl'to the bars ..7-,' the'clips of the tension wire of one section. wbein'g fastened to thc" jconnec'ting bars7. at v I .joiningsections said clips having-their free "ends attached I ismadefup rigid at the factory andcomplete being -preferably welded in itself, "the, tension and? distributing wires their intersections.- in anytsuitable manner;
