A NEW OR IMPROVED MODE OF APPLYING NON-CONDUCTING MATERIALS TO PREVENT THE RADIATION OF HEAT
Year: 1884

page_text: I SIGISMUND LEONI of 66 St Paul Street Packington Street in the County of
Middlesex, Gas Engineer do hereby declare the nature of iny said Invention for
A NEW OR IMPROVED MODE OF APPLYING NON-CONDUCTING MATERIALS TO PREVENT
THE RADIATION OF HEAT to be as follows:-
My invention has for its object the application of slag wool or other suitable
non-conducting substance to gas cooking ovens, or any apparatus in which it is
desirable to prevent the loss of heat by radiation.
And my improved method consists in lining the wood jacket, used to surround
ovens, boilers, and other heating apparatus, with a wire gauze cage or netting
between which gauze cage or netting and the wood jacket a layer of slag wool or
other non-conducting material is arranged. The object of the wire gauze cage or
netting being to prevent the slag wool or other non-conducting substance from
slipping down and thus leaving a portion of the heated surface of the apparatus
exposed to radiation, and also in the case of slag wool to prevent any corroding
nction upon the iron.
The above mentioned arrangement
simple in its application, readily repaired,
and does not add materially to the weight or bulk of the oven, boiler, or other
piece of apparatus to which it is applied.

PREVENT THE RADIATION OF HEAT and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:-
My Invention has for its object the application of slag wool or other suitable
nonconducting substance to gas cooking ovens, or any apparatus in which it is
desirable to prevent the loss of heat by radiation.
And my improved method consists in lining the wood jacket used to surround
ovens and other apparatus with a wire gauze cage or netting, between which.
gauze cage or netting and the wood jacket a layer of slag wool or other non-
conducting material is arranged. The said slag wool or other nonconducting
material acting also as a protection for the wood jacket against the effects of
external heat from the oven or other apparatus.
The object of the wire gauze cage or netting being to prevent the slag wool or
other nonconducting substance from slipping down and thus leaving a portion of
the heated surface of the apparatus exposed to radiation and also in the case of
slag wool to prevent any corroding action upon the iron.
The above mentioned arrangement is simple in its application, readily repaired,
and does not add materially to the weight or bulk of the oven or other apparatus
to which it is applied.
In order that my Invention may be fully understood I will proceed to describe it
more particularly by the aid of the accompanying Drawings in which are repre-
sented the parts of apparatus above referred to.
DESCRIPTION OF THE DRAWINGS.
Fig 1 is an elevation or side view of my nonconducting lining applied to a
portion of a wood jacket such as is used to surround ovens and other apparatus

page_text: 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
The application of slag wool or other suitable nonconducting material as a
lining to the wood jackets surrounding ovens and other apparatus in order to
prevent loss of heat by radiation substantially in the manner as herein before
described.
Dated this thirteenth day of February 1885.
