LATHING MAT.

Application lcd December 1, 1924. Serial No. 753,039.

My invention relates to a novel lathing mat for use in the construction of plastered and cemented surfaces in building construction, such as walls and ceilings, arches and columns, and it is particularly advantageous in the production of plastered and stuccoed walls and ceilings, since it is very easy of application and4 produces a very efficient binding surface for either plaster or cement.

, My invention consists chiefly of a series of parallelly disposed narrow strips of wood, spaced apart, and of any suitable uniform length, secured to and carried by two or more parallel metallic strands such as flexible wires, extending substantially at a right angle t0 the strips of wood, so as to form a mat composed of wooden strips and metallic retaining bands.

My invention further consists of a lathing mat composed of parallel spaced strips of wood secured to transverse metallic'bands by means of wires, which encircle the retaining band and each of the wooden strips, at the intersections of said wooden strips and said retaining bands.

My invention further consists of a lathing mat as mentioned above, having how-` ever, a layer of paper secured to said strips of wood on the sides thereof opposed to the metallic retaining bands, so as to form an efficient means of confining the plaster or cement during the, application thereof, to substantially the thickness of the mat, thus preventing any wastage of the plastering or cementing material due-to the same being exuded between adjacent strips of wood.

For the purpose of illustrating iiiy'invention, I have shown 'iii the accompanying drawings forms thereof which areat present preferred by me, since they will give in practice satisfactory and reliable results, al though it is to be understood that the vaiious instrumentalities of which my invention consists can be variously arranged andv organized and that my invention is not liniited to the precise arrangement and organization of these instrumentalities as herein shown and described.

Referring to the drawings, 1 designates the lath lstrips composed. of 'any suitable wood, and of substantially rectangular cross section, disposed parallelly and spaced apart equal distances substantially of the width of a strip. The strips'l are all of substantially the same length,"which may be any suitable lengthas required for the particular Work, although the length most commonly y used is one-yard. The strips 1 are carried by and secured to, two or more heavy flexible vwires 2 in a continuous nia-nner, so as to produce a mat, ofv awidth` equal to the length of the strips, and of any length that may 'be desired. Due to the flexibility of the retaining wires, the mat may be flexed transversely of the length thereof, thus permitting said mat to be rolled up into a coinpact roll which is easily handledand transported.

Each of said lath strips 1 is secured to each of the retaining wires 2 at the intersections thereof, by means of the thin securing wires 3, which are wrapped around said retaining wires '2 `firmly, and then closely encircle the particular lath strip, and are` then again wrapped around theretaining wire, thus securing the strips 1 to the retaining wires 2, both against transverse and 'longitudinal 'displacementl .The novel lathing mat thus produced, Mmay members of walls, ceilings or-columns, by simply placing said mat thereon with 'the rethrough the spaces between the lath, there is provided on the inner side of said mat, namely the side opposed to the retaining Wires, a layer of fibrous materialsuch .as the paper 7, which is secured to said strips of Wood by means of any suitable adhesive, as

shown in Figures 2, 3, 6 and 7.

In order to prevent any longitudinalslipping of the individual lath strips with respect to the mat, the securing Wire 3, as shovrn in Figure 4 on an enlargedA scale, is Wound around the retaining- Wire 2 sufficiently tight te cut into the latch strip a substantial distance, thereby fixing the said lath strip to said retaining Wirte, relative to any n 'initial cost of the lathing and in the cost of longitudinal movement thereof.

In order to produce a more effective binding of the plastering material, than would be obtained on the mattingv composed of rectangular strips as shown in Figures l to et inclusive, I may construct my novellathing mat of. Wooden lath strips having non-paral lel inclined sides such as those. of `a trapezot dal cross section shown in Figures 6 and 7.

In this modification of my novel lathing mat the lath strips 8 are secured in a similar manner to the retaining Wires 2, with the longer of the parallel sides of said trapezoidal crosssection adjacent to the retaining Wires, so as to produce, when assembled, grooves betweenthe adjacent laths strips, Which Will have inwardly inclined Walls. B y this modified form of my novel construction there is obtained a positive locking of the plaster in the inwardly enlarged grooves produced by the adjacent lath strips.

My novel lathing mat is adaptable to vertical as Well as horizontal surfaces and valso .to curved or arcuate surfaces of any degree produces a very durable surface. The lath by means of the retainngivires 2 and thev staples 5 at suitable intervals, said matting may be readily applied to any Wall or ceiling structure with a saving of time and also Without the aid of skilled help, thus reducing the cost tivo fold.

The staples 5 may be applied With great -rapidityand Without the aid of skilled help by the use of nailing guns designed for that purpose.v

In addition to the reduction of cost, in the its application to the building structure, the lathing of my novel construction produces a more effective plastering foundation, and hence a more durable plastered surface, than that produced by lathing material known heretofore.

It will new be apparent that I have devised a novel and useful lathing mat, Which embodies the features of advantage enumerated as desirable in the statement ofthe invention and the above description, and. While I have, in the present instance, shown and described a preferred embodiment thereof Which will give in practice satisfactory and reliable results, it is to be understood that such embodiment is susceptibleof modification in various particulars Without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described my invention, What I claim as new and desire to secure by Iletters Patent, is:-

A lathing mat consisting of a plurality of substantially parallelstrips of Wood having front and rear faces, a plurality of relatively thick and rigid retaining Wires extending transversely of said series of parallel strips of vvood along their front faces, a relatively thin securing Wire encirclingalternatively a retaining Wire and a ivooden strip and a sheet of paper adhesively secured to the rear faces of said Wooden strips, opposed to said retaining Wires'.
