Improvements in Non-conducting Coverings.
I, HENRY PERCY I BOTSON of 6
Baron's Court Road, West Kensington.
London, Works Manager, do hereby declare the nature of this invention to be as.
follows:
Inside the usual packing or composition of non conducting material used as a
covering or lagging for pipes and boilers and like purposes, I form spaces for air
between the said covering and the pipe or boiler. I effect this by forming ribs or
projections on the inner surface of the material.
These projections may be longitudinal spiral or annular and may be continuous.
or otherwise.
Spaces can also be left to clear sockets or other projections on the pipes.
I thus secure a layer of air so far as possible between the covering and the-
article covered.

COMPLETE SPECIFICATION.
Improvements in Non-conducting Coverings.
I, HENRY PERCY IBOTSON, of 6 Baron's Court Road, West Kensington,
London, Works Manager, 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 :-
Inside the usual packing or composition of non-conducting material used as a
covering or lagging for pipes and boilers and like purposes, 1 form spaces for air
between the said covering and the pipe or boiler.
I effect this by forming ribs or projections on the inner surface of the material..
These projections may be longitudinal, spiral or annular and may be continuous
or otherwise. Spaces can also be left to clear sockets or other projections on the
pipes.
I thus secure a layer of air so far as possible between the covering and the
article covered.
In the accompanying drawings I shew by way of example one form of non.
conducting pipe-covering according to my invention.
Fig. 1 is a longitudinal and Fig. 2 is a transverse section. A is the non
conducting material made as a hollow cylinder preferably in halves so that
inwardly projecting ribs B can be readily formed in moulding the material, and
the two halves can be put on pipe and secured together by a wrapping C of
canvas or other fabric. Between the ribs B are the air spaces D which may be of
more or less depth as desired.
When the pipes are socket jointed, the recesses or some of them are made.
sufficiently deep to enclose the sockets. The ribs B may be annular as shewn, or
LD

page_text: they might be helical or longitudinal, either continuous or in separate lengths,
requiring only to be sufficient to give the covering a sound bearing on the pipe
or body covered, but leaving most of the space within the covering to contain air.
The projection of the ribs internally also gives facility for rubbing them more
or less off upon surfaces more or less irregular so that the two halves of the
covering can be brought close together at their jointing.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
Non conducting coverings or laggings for pipes, boilers and like purposes,
moulded with internal ribs or projections and intermediate air spaces, substantially
as and for the purpose set forth.
