lThis invention has reference to an iarticle 'of manufacture which Acomprises a fabric, "preferably made of wire and Awhich iis adapted for use as :a

reinforcing material for concrete and other types 5 of construction in monolithic form. Y

The invention Y'has for its principal -bject "to provide :in such a `fabric means of -a pre-'determined length forproperlyspacing the kbody "wires, constituting the fabric, from the surface 'of the material .cast 'and if employed in 'construction work in connection withthe 'Walls `anc'l-ceilings-of buildings, such spacing means will propelylspace the fabric from the studding or other support, so that when plaster is applied it will get behind the fabric so that when the wall is com; pleted the fabric will be embedded or completely surrounded by the plaster, thereby giving a stronger and more durable wall construction.

The invention has for a further object to combine the spacing means in well known types of Wire fabrics, as for example, those types made up of line wires or longitudinal strands and stays or pickets or cross-wires and where the connections at the intersections of such wires comprise a wrap or staple connection. An end or ends of the wraps or an end or ends of the staple ties being extended laterally or at right angles to the body of the fabric and of such pre-determined length to properly space the body of the fabric from the surface of the material reinforced. In carrying out the invention the projecting portions or extensions of the Wraps may be extended laterally from only one side of the fabric or from both sides, as occasion or working conditions I` may require. Also, such extensions or projections may be provided at the connection between the stays or pickets or cross-wires with the marginal or selvage wires, the same as at the intersections of such cross-wires with the intermediate line wires.

Fig. 1 is a face view, broken away, of a wire fabric composed of line and cross-wires, the latter comprising sections which unite at the line wires v and twisted or coiled together thereabout, an end of one of the sections of each cross-wire projecting or extending laterally from the fabric, on one side, for a predetermined distance;

Fig. 2 is an edge view, broken away, of the fabric shown in Fig. 1;

Fig. 3 is a view similar to Fig. 2 and of a like fabric as shown in Fig. l, except that the top and bottom sections of the cross-wire which are coiled about the selvage or marginal wires have lateral terminal projecting ends, as do certain of the intermediate sections;

Fig. 4 is a view similar to Fig. `3 except that A'the rends Aof ethe `respective Vsections vrof the Jcross- -wire Which tconnect with the intermediate line Wires *project laterally 'ffrom Aand on-opposite sides vof the fabric, `at points `Aof intersection with said U0 Ainterrnec'liate Iline Wires;

Fig. 5 xisa -view similar "to Fig. 4 except that the 'topand bottom sections ofthe -cross lwire which are coiled about the selvage or marginal wires are"loopedback -on themselves in opposite directions to provide lateral Aextensions lor vkprojections fon opposite -sides of `the fabric;

Fig. 6 is a fface view, -somewhat Asimilar to Fig. "1 Vexcept that the stay or cross-wire fis ya straight -or stiff 4single AWire `lthe opposite `ends 'of 7.0 which are coiled or Wrapped about the selvage or marginal wires and with their ends projecting or extending laterally from the body of the fabric, the body of the cross-wire being connected at its intersection with the line wires by staples, an end of which projects or extends laterally from the body of the fabric; and

Fig. 7 is an edge View of Fig. 6.

In each of the figures the line or longitudinal wires are designated 1 with the outside wires referred to as selvage or marginal wires and those between as the intermediate wires. These wires may be spaced equidistantly from each other or in any spaced relation or arrangement as desired or working conditions require.

The stays or pickets or cross-wires are designated 2. In all the gures, except Figs. 6 and 7, these cross-wires comprise sections extending from marginal wire to marginal wire, the meeting ends of adjacent sections at the intermediate line wires being preferably intercoiled about such wires, as at 3, while the outer ends of the top and bottom sections of the cross-wires are coiled about the marginal or selvage wires, as at 4. To provide the spacing members for the fabric, an end of certain of the sections of the cross-wire are extended or projected laterally for a predetermined distance from one side of the fabric, as at 5, at each intermediate line wire, see Figs. 1, 2 and 3; or an end of each alternate section of a cross-Wire may be extended or projected laterally for a predetermined distance from opposite sides of the fabric, as at 6 and 7, at each intermediate line wire, see Figs. 4 and 5. In Figs. 1 and 2 there are no projections from the terminals of the coils 4 around the marginal Wires. In Figs. 3 and 4 the terminal ends of these coils 4 project laterally from the body of the fabric, for a predetermined distance, as at 8. In Fig. 5 the terminals of the coils 4 are looped back on themselves, as at 9, to provide eX- tensions projecting laterally from opposite sides of the fabric. It is obvious from the foregoing description that, employing a fabric, the crosswires of which are made of a series :of sections that the spacing members which are'located at the intersections of the cross-Wires with the line or longitudinal Wires may extend laterally from only one side of the fabric or from both sides as occasion or Working conditions may require;

In Figs. 6 and 7 the cross-wires, as pointed out, are uncut straight single Wires having their terminal ends coiled about the marginal or selvage Wires, as at 10, with the terminal ends projecting laterally from the fabric, as at 11, to provide the spacing elements. Where the cross-wires 2 intersect the intermediate line Wires they are connected by staples 12 with an end of the staples projecting laterally from the fabric, as at 13, to provide the spacing elements.

What We claim is:-

1. An article of manufacture comprising a wire fabric including line and cross-Wires connected at their intersections, certain of said connections provided with lateral extensions projecting from one side of the fabric, While certain other of said connections are provided with lateral extensions which project fromv opposite sides of the fabric.

2. A Wire fabric for reinforcing materials comprising a plurality of spaced parallel line Wires and a plurality of spaced transversely disposed cross-wires, and means for spacing the bodyof the fabric from the surface of the material Which comprises members of predetermined length projecting at right angles from the plane of the body of the fabric and which also constitute connecting means for the line and cross-wires Where they intersect.

3. A Wire fabric for reinforcing materials comprising a plurality of spaced line Wires and a plurality of spaced cross-Wires, and means for spacing the body of the fabric from the surface of the material which comprises members of predetermined length projecting laterally from opposite sides of the body of the fabric and which also constitute connecting means for the line and cross-Wires where they intersect.

4. An article of manufacture comprising a wire fabricmade up of parallel spaced line Wires and transversely spaced cross wires whereby to characterize a square mesh fabric presenting a substantially at mat,1 and means connecting said Wires Where they intersect, certain of which said means having a portion With a free terminal projecting at right angles from the plane of the body of the fabric for a predetermined distance for seating against a supporting surface to space the fabric from the latter.

5. An article of manufacture comprising a Wire mesh fabric formed of intersecting wires connectediat their intersections, certain of the connections having extensions projecting laterally from a side face of the fabric, the terminals of which extensions are free for seating against a supporting surface thereby to hold the fabric spaced fromy such surface.
