Specification of Letters Patent.

Application filed November 13, 1909. Serial No. 527,819.

To all whom it may concern:

Be it known that I, ALEXANDER P. WHITE,

a citizen of the United States, residing in county, State of New Jerprovement in Lathing, of which the following is a specification.

'This invention relates to lathing Which'is applied to Walls and ceilings in building construction, for the purpose of holding plaster; and the object of the invention is to provide a cheap and improved lathing for this purpose.

As is well known, metallic wire fabrics made by weaving or interlacing wire strands are used largely at the present time for lath- Sheet metal suitably perforated ;to

slitted and drawn open at the slits, to form what is known as expanded metal. In all thesearticles, when the strands or portions between the openings are thin or of small diameter, the tendency of the metal is to cut the plaster. The narrow surfaces offer little resistance to the mortar substance and much care is necessary to make the application of the plaster and avoid waste of the same. If the metal surfaces were increased in area, the resultant increase iin Weight would render the cost excessive and make very difficult the manipulation of the metallic body in its application in places where it must be bent into certain forms.

By my invention, I make a novel and practical combination of metal and non-metallic substances, which not only overcomes the present objections but reduces very ma terially the cost of the lathing. It permits a more desirable distribution or location of the metal used, in that it is possible to concentrate the metal at given places where it. will give positive strength to the plaster body. This will be better understood when attention is directed to the fact-that in many cases the light wire fabrics used arepracticall; merely vehicles to hold the plaster "until it sets an'd becomes rigid; After it has tions which I employ, as hereinafter defactored.

plaster. My

scribed, cover so much of the surface that it is not necessary to rely on the metal wires to perform this service. Hence a given quantity of metal; can be fixed in thicker strands that reinforce the plaster structure and the studding that holds the lathing can be placed at greater distances, thus effecting further decided economy.

In accordance with my invention, I provide a lathing which comprises a metallic fabric, or grid, having combined therewith interstitial fillers of a lighter, and preferably non-metallic fi1ler. In carrying out my invention, I prefer to use 'for these'fillers the heavy indurated papers, which are made by processes well known in the paper manufacturing art by pressing and rolling fibrous material into sheets or boards. Iform this material in strips. These strips can also be cut from the sheets or boards as now manuwidths of about one quarter 'of an inch and to arrange them in parallel rows in the lathing fabric, as shown in the drawings. I

select metal wire of a suitable gage, say 18 standard gage and weave these wires into a network placing at suitable intervals in the network the fiber strips in lieu of wires. I prefer to place the fiber strips so that the Patented June 7, 1910.

I prefer tocut the strips in space between them will be about One-half inch and have one wire strand between each strip, or in other words, ,to make the metal and the fiberstrands alternate. Almost any of the methods of interlacing wires to make woven wire work are available to produce this material. 4

In the drawings, Figures i, 2, and time plan v ews of portions of lathing showing. 1

difierent forms of my invention; and F ig. 4 is a detail sectional view showinganother modification.

In Fig. '1, I show a construction using Y plain wires 2 and 3, the wires of two series being passed alternately over and under each other, and the paper strips 4 being held in the loops formed by this weaving-of the wires. Theends of the wires? are shown as hooked or coiled overthe top wire 3 at 2'.

In Fig. 2, a similar construction is except that twisted wires ployed.

shown, 5 and 6 are em These heavier wires give positivestrength to the structure, and typify the explanation In Fig.3, I show a construction'in which hereinbefore given with reference to the desiral'iility-of concentrating the metal. The smaller wires 8 and 9 serve to hold the fabric together and also to reduce the openings be tween the non-metallic strips. The ends of the wires 8 and 9 may be hookecl'or coiled around the heavier wires at the edges of the fabric as shown at 8" and 9. As many of these heavier wires, spaced at intervals, may

be employed, as may be desired.

In Fig. l, I illustrate a construction in which the paper strips 10 are perforated edgcwise, as indicated at 11, and the trans-- verse itabric wires iii are passed through these perforations.

The caper or fiber strips are practically meter-proof, and .l. prefer to use this class of materialsalthough other material may obriously employml.

it will be obvious that my invention is susceptible of various other embodiments shown, and I wish to be understood as using;

the words across and interwoven in my 0 ms to include such structure.
