Covering.
I, WALTER HARVEY CHAPMAN, of Number One, Portland Road, Holland Park
Avenue, London, W., Engineer, do hereby declare the nature of this invention
to be as follows:-
-
My invention has reference to an improved and novel method of applying
heat-insulating or cold-insulating materials to boilers, pipes, or other surfaces,
producing thereby large air-spaces between the surface to be insulated and the
heat-insulating or cold-insulating material employed.
In the accompanying drawings, in which the same letters refer to the same
parts in the several figures.
Fig. 1 illustrates a sectional elevation of a pipe insulated by my method.
Fig. 2 illustrates an end sectional view of the same pipe insulated, taken
at A B Fig. 1.
In Fig. 2
c represents the pipe.
d represents the air-space creating strip.
e is the heat-insulating or cold-insulating material employed.
f is the outer covering.
The action or application of my invention is as follows:--
First. I apply the corrugated or waved metal or other strip, as shown in
Figures 1 and 2, by wrapping same round the boilers, pipes or other surfaces
to be heat-insulated or cold-insulated, or by fixing the corrugated or waved
metal or other strip longitudinally to obtain the same result, or by directly
following the contour of the surface to be so insulated.
It is obvious that this strip may be applied very closely or at wide intervals,
as circumstances may require.
Second. I place upon this before mentioned strip the heat-insulating or
cold-insulating material to be employed, using preferably for this, silicate
cotton or slag wool, hair felt or asbestos and applying to either of these heat-
insulating or cold-insulating materials a sufficiently durable covering, where
necessary or desirable. It is clear also that these constituent parts may be
united together and directly applied in one operation.
Dated, this Fourth day of May 1899.

I, WALTER HARVEY CHAPMAN, of 1, Portland Road, Holland Park, Avenue,
London, W., Electrical Engineer, 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:--
My invention has reference to an improved and novel method of applying
heat-insulating or cold-insulating materials to boilers, pipes, or other surfaces,
producing thereby large air-spaces between the surface to be insulated and the
heat-insulating or cold-insulating material employed.
In the drawings left with the Provisional Specification, in which the same
letters refer to the same parts in the several figures
Fig. 1 illustrates a sectional elevation of a pipe insulated by my method.
Fig. 2 illustrates an end sectional view of the same pipe insulated, taken
at A B.
In Fig. 2
C is the pipe.
D is the air-space creating strip.
E is the heat-insulating or cold-insulating material employed.
F is the outer covering:
The action or application of my invention is as follows.
First. I apply the corrugated or waved metal or other strip, as shown in
Figs. 1 and 2, by wrapping same round the boilers, pipes, or other surfaces
to be heat-insulated or cold-insulated, or by fixing the corrugated or waved
metal or other strip longitudinally to obtain the same result, or by directly
following the contour of the surface to be so insulated. It is obvious that this
strip may be applied very closely or at wide intervals, as circumstances may
require.
Second. I place upon this before mentioned strip the heat-insulating or cold-
insulating material to be employed, using preferably for this purpose asbestos,
slag wool or silicate cotton, hair felt, or magnesia and applying to either of
these heat-insulating or cold-insulating materials a sufficiently durable material
as a finishing outside covering, where necessary or desirable. It is clear also
that these constituent parts may be united together and directly applied in
one operation.
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 and novel method of preventing the loss of heat or cold by the
creation of air-spaces between any surface to be heat-insulated or cold-insulated,
and the heat-insulating or cold-insulating material employed, substantially as
described and illustrated in the drawings left with the Provisional Specification.
Dated, this 3rd day of March 1900.
