I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co. Patent Agents,
Southampton Buildings, in the county of Middlesex do hereby declare the nature
of this invention to be as follows :-
This invention relates to an improved covering for the walls, partitions or ceilings
of buildings which covering I term a "compound finish or lining."
As is well known, walls, partitions, ceilings, and the like have heretofore been
frequently composed of a backing of wire-netting of suitable strength; and a covering
composed of plastic material, such as ordinary lime-plaster, which is applied to the
netting and forced through its interstices or meshes, and thereby keyed, as it were,
and secured to and about the wires of the netting; the said netting being first secured
in place and then the plastic material applied to it and properly smoothed and
evened off.
In the construction of walls and the like in this manner, as is well known, the
plastic material passes through the meshes to the back side of the wire-netting without
restraint or hindrance, (especially is this so if the mesh of the netting is somewhat
open, which for economy it is desirable it should be,) resulting in the consumption
of an amount of plastic material largely in excess of that really and practically
required.
The object of this invention is to obviate these objections without otherwise
materially increasing the cost of the wall or the like, but in fact economizing its cost,

page_text: by enabling a very open meshed wire-netting to be used, as compared with the mesh
heretofore capable of being practically and serviceably used, and to this end, the
invention consists, of the improvements hereinafter described.
In carrying the said invention into practice I first apply to a suitable foundation a
layer of material, such as paper, pulped board, wood or metal, but preferably paper,
or pulped board, which has been made water-proof and fire-proof, in any suitable
manner the said layer directly covering the wall, ceiling or partition, and being
properly secured in position. A layer of wire or other netting or equivalent material
is next placed over said paper-layer and secured in position in any suitable manner, a
space being preferably left between its wires or strands and said paper-layer. I next apply
a layer of plastic material, such as ordinary lime-plaster or other suitable material, to
the outside of the netting-layer, the said plastic-material being forced into and through
the meshes of the netting against the paper-layer behind it and also, if a space is left
between the wires of the netting-layer and the paper-layer, into said space, filling it
and the openings or meshes of the netting.

page_text: I HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to an improved covering for the walls, partitions or ceilings
of buildings which covering I term a "compound finish or lining."
As is well known walls, partitions, ceilings and the like have heretofore been
frequently composed of a backing of wire-netting of suitable strength; and a covering
composed of plastic material, such as ordinary lime-plaster, which is applied to the
netting and forced through its interstices or meshes and thereby keyed as it were and
secured to and about the wires of the netting, the said netting being first secured in
place and then the plastic material applied to it and properly smoothed and evened off.
In the construction of walls and the like in this manner as is well known, the
plastic material passes through the meshes to the back-side of the wire-netting
without restraint or hindrance, (especially is this so if the mesh of the netting is
somewhat open which for economy it is desirable it should be,) resulting in the
consumption of an amount of plastic material largely in excess of that really and
practically required.
The object of this invention is to obviate these objections without otherwise
materially increasing the cost of the wall or the like but in fact economizing its cost,
by enabling a very open meshed wire-netting to be used as compared with the mesh
heretofore capable of being practically and serviceably used, and to this end, the
invention consists of a lining or finish for walls, ceilings, partitions and the like.
This lining or finish comprises a layer of material, such as paper pulped board,
wood, or metal, but preferably paper, or pulped board which has been made water-
proof and fire-proof in any suitable manner the said layer directly covering the wall,
ceiling or partition, and being properly secured in position; a layer of wire or other
netting or equivalent material is next placed over said paper-layer and secured in
position in any suitable manner, a space being preferably left between its wires or
strands and said paper-layer. I next apply a layer of plastic material, such as ordinary
lime-plaster or other suitable material, to the outside of the netting-layer said plastic
material being forced into and through the meshes of the netting against the paper
layer behind it and also, if a space is left between the wires of the netting-layer

page_text: and the paper-layer, into said space, filling it and the openings or meshes of the
netting.
In the accompanying drawing one method of carrying out this invention is
illustrated.
Figure 1 is a sectional perspective view of a portion of the studding of a wall,
lined or finished in accordance therewith.
Figure 2 is a horizontal section, on line 2-2, figure 1. A is the studding; B, B, are
the furring-strips nailed to the studding A; C is a layer of material, such as paper,
or pulped board, nailed to the furring-strips B, B; D, D are a series of strips of
paper-board nailed to the layer C of paper-board and to and in line with the furring B
along the length of the studding A; E is a layer of netting made of wire or of strands
of other suitable material and securely nailed and fastened against the paper-strips D.
F is an open space between the layer E of netting and the layer of pulped-
board, and G is a layer of plastic material such as ordinary lime-plaster, or other
suitable material having similar adhesiveness hardness and fire and water proof
qualities but preferably a plastic material or compound, such as described in the
schedule annexed to the Letters Patent of the United States, issued to Henry W.
Merritt of Boston Massachussets, dated July 14, 1885 No. 322,307.

The pulped-board C, which, preferably, is water-proof as also fire-proof, but for
which other material such as wood or metal may be substituted, forms the inner
surface or layer, the plastic material G the outer surface or layer, and the netting E,
or other equivalent sheet material, the intermediate surface or layer of the compound
finish or lining of this invention. The plastic material fills the meshes of the netting E
and also enters into and is confined in the space F which is between the netting
and the pulped board, the pulped-board limiting and restraining the inward movement
of the plastic-material which in the making up of the lining or finish is applied to
the outside of the netting and forced through its meshes. Again as the plastic
material is so applied the pulped-board acts to spread and dispose it at the back of
and around, and to confine it most closely to, the strands of the netting thus so as the
plastic material dries and hardens, the better securing the union and adhesion of it
with the strands of the netting.
In constructing the lining or finish described, the inner layer C is first secured in
place, and then the intermediate layer E of netting, preferably leaving a space F
between its strands and the inner layer C; afterwards the plastic material is applied
to the outside of the netting and forced into its meshes and also into the space F
between it and the inner layer C, the whole resulting in the production of a lining or
finish, in one form in accordance with the invention.
As particularly shown and described the space F between the inner layer C and
intermediate layer E of netting is produced by separate strips D of paper applied to
the inner layer. These strips D may be of other material and, again, they may be
first attached to the netting and then to the paper-board, and also they may be
dispensed with and a space F secured by raised portions or knobs or ribs of the
layer C or pulp-board or of the layer E or netting, or otherwise, in any suitable
manner, the essential feature of this invention, in this regard, being an intermediato
space, or in other words, a space back of and between the strands of the netting E
and the inner layer C of sheet-material.
The construction of a lining or finish as herein described allows netting of a most
open mesh to be used, for the reason that the passage of the plastic-material through the
meshes is restrained and limited by the inner layer C, and with an intermediate space F,
the plastic material is afforded ample opportunity to lock itself about, upon and back
of the strands making up the netting. In this lining, or finish the netting is in
reality the part depended upon to support the plastic-material, but in the construction
of the lining, and also, as is obvious, even after its construction, the inner layer (
serves a most useful purpose, viz. in the first instance, as a limit or restraint to the
inward movement of the plastic-material as a surface for the plastic-material to adhere
to between the wires and in the open meshes of the netting and to form a space,

page_text: between the inner layer C and the wires of the intermediate layer E of netting, for
the entrance and passage of the plastic-material to and around the back of the wires
serving as a means to confine and hold the plastic material, as it dries and sets, in
close contact with and around, and thus the better to unite it to the wires; and in the
second instance, as a protection and more particularly so, if it is water and fire-proof,
against moisture, dampness and fire.
The plastic compound patented by Mr. Merritt and herein referred to, is the plastic
compound, as before stated most preferable to be used but it is not intended to limit
this invention thereto.
In the construction of the lining or finish of this invention it is preferable to use
a netting of wire, but netting made of strands of other material as for instance of
animal or vegetable fibre, and again a perforated plate of metal or other material,
may be used.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed as communicated to me by my
foreign correspondent I declare that what I claim is
First. A lining or finish for walls, ceilings, partitions and the like constructed of
an inner layer of pulped-board or other suitable material an intermediate layer of
netting or such like material, and an outer layer of plastic or such like material, all
substantially as described, for the purpose specified.
Second. A finish or lining for walls, ceilings, partitions and the like constructed of
an inner layer of pulped-board or other suitable material and a layer of netting or
such like material with a space between said two layers, in combination with a layer
of plastic or such like material applied at the outside of the intermediate layer, and
entering into the space between it and the inner layer, all substantially as described
for the purpose specified.
