AN IMPROVED MODE OF SECURING " AND PROTECTING THE NON-CONDUCTING COVERING OF BOILERS AND PIPES OR OTHER VESSELS CONTAINING STEAM, WATER, OR OTHER FLUIDS OR GASES
Year: 1884

page_text: I, CHARLES FREDERICK WORMALD of No 2 St Nicholas Buildings in the City and
County of Newcastle-upon-Tyne Manufacturer of non-conducting composition, do
hereby declare the nature of said invention for "AN IMPROVED MODE OF SECURING
"
AND PROTECTING THE NON-CONDUCTING COVERING OF BOILERS AND PIPES OR
OTHER VESSELS CONTAINING STEAM, WATER, OR OTHER FLUIDS OR GASES to be
as follows:-
=
•
The various non-conducting compositious used to cover steam boilers, steam pipes
or other vessels containing steam or heated fluids or gases to prevent loss of internal
heat by radiation or to prevent conduction of external heat to cold fluids or gases
unless secured by bands, wire netting, sheet iron or other covering soon crack and
fall off leaving the surfaces exposed.
Wire netting has hitherto been the most efficient covering protection but it
is liable to rapid corrosion, while sheet iron has the same fault and is besides
difficult to apply requiring skilful workmen to fit and fix it, especially to spheres
or portions of spheres, bends of pipes, and junctions.
My object has been to adopt some material not liable to corrosion, easy of
application (without special skill) not too expensive in price, and I propose to use
thin sheet lead which fulfils these conditions in every way. The softness and
ductility of sheet lead enables it to be worked so as to adapt itself to any form of
surface and it will resist the corrosive action of water, foul air or gases and of acids
generally. It can be applied in large or small sheets or in strips preferably lapped
spirally the joints being either overlapped and fused or "pinned" or they may be
bound with straps.
It will be found especially valuable for covering pipes in shafts or underground
passages in mines or for ranges of pipes in chemical works. In case of leaky joints
or rivets in boilers it will indicate on its surface the position of the leak which can
be readily opened out and repaired.

Containing Steam, Water, or other Fluids or Gases.
I CHARLES FREDERICK WORMALD of 2 St Nicholas Buildings in the City and
County of Newcastle upon Tyne, Manufacturer of non-conducting composition
do hereby declare the nature of said invention of:-"AN IMPROVED MODE OF
SECURING AND PROTECTING THE NON-CONDUCTING COVERING OF BOILERS AND
PIPES OR OTHER VESSELS CONTAINING STEAM, WATER OR OTHER FLUIDS OR
GASES " and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
The various non-conducting compositions used to cover steam boilers, steam pipes
or other vessels containing steam or heated fluids or gases to prevent loss of internal
heat by radiation, or to prevent conduction of external heat to cold fluids or gases,
unless secured by bands, wire netting, sheet iron or other covering, soon crack and
fall off leaving the surfaces exposed.
Wire netting has hitherto been the most efficient covering protection but it
is liable to rapid corrosion, while sheet iron has the same fault and is besides
difficult to apply requiring skilful workmen to fit and fix it, especially to spheres
or portions of spheres, bends of pipes and junctions.
My object has been to adopt some material not liable to corrosion, easy of
application (without special skill) not too expensive in price, 'and I propose to use
thin sheet lead which fulfils these conditions in every way. The softness and
ductility of sheet lead enable it to be worked so as to adapt itself to any form of
surface and it will resist the corrosive action of water, foul air or gases and of acids
generally. It can be applied in large or small sheets or in strips, preferably lapped
spirally, the joints being either overlapped and fused or "pinned" or they may be
bound with straps. It will be found especially valuable for covering pipes in
shafts, or underground passages, in mines or for ranges of pipes in Chemical worka
In case of leaky joints or rivets in boilers it will indicate on its surface the position
of the leak which can be readily opened out and repaired.
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 and use of sheet lead for the purpose of securing and protecting
the non-conducting coverings of boilers and pipes or other vessels containing steam,
water or other fluids or gases substantially as described.
