I, SAMUEL TURNER, of the Firm of Turner Brothers, of Spotland, Rochdale,
in the County of Lancaster, Asbestos Manufacturer, do hereby declare the nature
of this invention to be as follows:-
1
For the purposes of my invention I propose to manufacture sheets of asbestos
paper, or millboard with a corrugated surface or surfaces, my object being to
manufacture a cellular non-conducting material to prevent the loss of heat by
radiation, in the transmission of steam, hot gases or liquids and for other similar
purposes.
A sheet of asbestos paper or millboard is formed into corrugations by any well
known process such as crimping or embossing (I prefer crimping), and in order
to maintain the crimped form I paste or cement or otherwise secure another sheet
of uncrimped asbestos paper or millboard to one surface thereof.
The sheet thus formed may then be wound or coiled layer upon layer round the
pipe boiler or other object to be protected, until the required thickness is obtained.
The air cells formed by the corrugations act as interceptors of the heat and improve
the non-conductivity of the material, at the same time that it is practically inde-
structible by heat. The whole may then for better protection be covered with
a layer of cloth preferably of asbestos or the same may be painted or vamished
or otherwise finished or protected as required. The corrugations or air spaces
may be formed in various ways and be of varying shape or a corrugated sheet
may be formed by laying and securing strips of asbestos millboard of varying
section crosswise on a sheet of the same material or upon asbestos cloth, or an
asbestos cloth may be woven with strips of millboard inserted crosswise after the
manner of weft or instead of the strips of millboard, thick plied asbestos yarn or
cordage may be interwoven at suitable intervals to form the corrugations and air
cells.
I propose also to construct mattresses of the same material by laying it layer
upon layer until the required thickness is obtained, the layers thus formed being
secured together by pasting cementing or stitching with wire or other material,
or by any other convenient method as may be required, or the same may be used
without pasting or securing together if preferred. The outer layer or layers may
then, for better protection, be covered with, or the whole may be enveloped in
cloth, preferably of asbestos, or the same may be painted or varnished as required.
Mattresses thus constructed may be cut into strips of the required size and be
laid upon the pipe, boiler, or other article to be protected and the ends be secured
together by sewing or by staples or by any other convenient method. The mat-

page_text: tresses may, when used to protect a boiler or other similar vessel or structure be
cut or shaped to suit any fittings with which they may come in contact.

An Improved Non-conducting Material for Covering Steam and
Water Pipes and for other similar purposes.
I, SAMUEL TURNER, of the Firm of Turner Brothers, of Spotland, Rochdale,
in the County of Lancaster, Asbestos Manufacturer, 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:-
-
The object of this invention is to manufacture a cellular non-conducting material
to prevent the loss of heat by radiation, in the transmission of steam, hot gases,
or liquids through pipes and for other similar purposes, where a non-conducting
medium is required.
On the drawings annexed to this specification.
Fig. 1 is a diagram illustrating the manufacture of the improved cellular
material. Fig. 2 is a section of a steam pipe protected by superposed layers of
the said material.
Figs. 3 and 4 illustrate different methods of forming the corrugated material,
and Fig. 5 is a section of a pad or mattress formed by several superposed layers
thereof, and adapted for covering boilers or other extended surfaces.
According to my invention a sheet of asbestos paper or mill-board is first formed
into corrugations either transversely longitudinally or otherwise by any well
known process such as crimping or embossing (I prefer crimping) as shown at «
Fig. 1 on the drawing and in order to maintain this crimped or corrugated form
I paste, cement, or otherwise secure another sheet of plain or unerimped asbestos
paper or millboard b to one surface thereof.
The compound sheet thus formed may then be wound of coiled; layer upon layer,
round the pipe, boiler, or other object to be protected until the required thickness
is obtained as shown by the sectional view Fig. 2 on which c represents a steam
pipe so protected.
.
The air cells formed by the corrugations act as interceptors of the heat pre-
venting its escape or radiation and improving the non-conductivity of the material,
at the same time that it is practically indestructible by heat. The layers of corru-
gated material may be secured in place by means of staples, metal bands, wire,
or otherwise, and if preferred for better protection may be covered with an outer
layer of cloth (preferably of asbestos) or the same may be painted, or varnished, or
otherwise finished or protected as required.
The corrugations or air cells may be formed in various ways and be of varying
shape, or a corrugated sheet may be formed' by laying or securing strips of asbestos
millboard of varying section crosswise on a flat sheet of the same material as
shown at d Fig. 3. Or, an asbestos cloth may be woven with strips of millboard
inserted cross-wise after the manner of weft as shown at Fig. 4, at suitable intervals
to form the corrugations and air cells.
I propose also instead of coiling the material to construct thick mattresses or
pads of the same material by piling it layer upon layer until the required thickness
is obtained, the layers thus formed being secured together by pasting, cementing, or

page_text: stitching with wire or other material or by any other convenient method (as illus-
trated by Fig. 5) and these mattresses or pads, when used to protect a boiler or
other similar vessel or structure, may be cut or shaped, to suit any fittings with
which they may come in contact.
.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
-
An improved non-conducting material for covering steam and water pipes and
for other similar purposes consisting of sheets of asbestos, paper, or mill-board, or
asbestos cloth, with a corrugated surface, or surfaces, used singly or doubled, or
wound or coiled in two or more thicknesses, so as to manufacture a cellular non-
conducting material, substantially in the manner and for the purposes herein-
before described.
