Patented May 14, 1940 UNITED STATES PATENT OFFHIE Application July 6, 1937, Serial No. 152,132 Renewed April 8, 1940 4 Claims.

This invention relates generally to improvements in fabricated devicesand has particular reference to fabricated elements capable of being applied to the walls of a building to bind and hold the plaster in said structures.

The principal object of the invention is to provide a combined metallic fabricated material that may be produced in sections to be later applied to the uprights of a building structure, that is, to the studding of said structure to properly hold and bond the plaster finish to be applied thereto in the final finishing of the Walls of the building.

Another object of the invention is to produce a fabricated material in the form of lath that is cheap to manufacture, that combines rigidity, is pliable and that may be quickly and easily assembled in units to be applied to the walls of a structure of any description.

A further object of the invention is to provide a fabricated section or sections of the character set forth that may be produced in large quantities and in a continuous operation.

Additional to the foregoing objects is that of providing a combined metallic and fabric lathing structure that embodies means for stiffening the structure of the material, means for waterproofing the same, and means for holding the plaster which may be later applied thereto.

Other objects and advantages of the invention will become apparent with reference to the accompanying drawing in which- Figure l is a plan view generally illustrating the features of my invention; and

Figure 2 is an enlarged sectional view taken on the line 2-2 of Figure 1.

It is apparent that various metal lath constructions have been produced in the art of building devices, but none of these combine the features included in the present structure, in that, to my knowledge, all so-called metal lathing of this type consists entirely of fabricated metal, while in the present device a combination of elements is produced to not only combine a metallic structural arrangement of elements but to also include means for waterproofing the same as well.

The preferred form of my invention is shown in the drawing and includes a section of fabricated material 5 generally indicated in the figures and which may be turned out in an elongated sheet and cut in the desired sections.

This sheet of fabricated material is constituted of a corrugated base paper of coarse character,

a waterproof lining 1 preferably of tin foil, metallic stiifeners 8 of U-configuratio'n and a covering 9 of burlap of open mesh material, the whole being wire stitched together by means of wire 5 stitching Hi.

In this manner a composite metallic and. fabric section is formed which combines metal stiffeners, a light corrugated body section, means for waterproofing the same, and means for 10 stitching the sections together as a unit.

The transverse stififening ribs 8 are stitched to the structure as indicated by the stitching l l in Figure 1. 1

It will, therefore, be apparent that a plaster- 16 board backing has been produced that is light in weight, may be easily cut to the desired size, and that may be quickly applied to the studding or uprights of any building structure.

I claim and desire to secure by Letters Patent 20 of the United States the following:

1. In a fabricated lathing of the class described, a non-metallic base, a waterproofing consisting of tin foil arranged against the base, stiffening elements positioned upon said base, a non-metallic element arranged over the stiffening elements, the whole being wire stitched together as a unit.

2. A section of fabricated material comprising lathing sections capable of being applied to a building structure to receive a plaster finish, said sections being constituted of a corrugated base,

a tin foil waterproofing section, netting arranged above the base section, and wire stitching extending thru all sections that combine the same in a unit.

3. A fabricated material for building structures providing a base for plaster finish in sheet form, said base consisting of metallic and nonmetallic elements in sheet form' superimposed 40 uponeachother, wire stitched together as units, and metallic stiffeners riveted upon the body of the material tohold the same in position.

4. In a fabricated lathing of the class described, a non-metallic corrugated base in sheet form, a waterproofing element also in sheet form arranged upon said base, stiffening elements in sheet form riveted upon said base, and a netting element in sheet form superimposed and wire stitched to the stiflening elements and secured to said base. i i
