Improvements in Steam Boiler. Furnaces and Flues.
We, JOHN DEVONSHIRE ELLIS, Managing Director of John Brown & Co. Ld.,..
of Atlas Works, Sheffield in the County of York and JOSEPH NODDER of the
same place, Ironworks Manager, do hereby declare the nature of this invention to
be as follows:-
:-
The object of this invention is to provide boiler furnaces, or flues, in, which the
heating effect is improved by reason of the distance from fire to water being less
than hitherto in corrugated sections, the circulation of water being also improved,
whilst great strength against collapse, from high working pressures is secured..
According to this invention the furnace, or flue, is formed of a longitudinal section
presenting waved, or curved, lines, entirely, without flat, or plain, portions, the
curves being so arranged that long, or sweeping curves of large radius alternate
with narrower curves of less radius, the said curves being all arranged so that their
concavities are presented to the water side of the furnace, or flue, and their
convexities are presented to the fire side of the furnace, or flue. The furnace, or
flue, thus presents, on the water side, alternating depressions of long and short
radius, joined by short curved projecting portions.
Dated this 16th day of September 1895.

Improvements in Steam Boiler Furnaces and Flues.
We, JOHN DEVONSHIRE ELLIS Managing Director of John Brown & Company
Limited of Atlas Works Sheffield in the County of York and JOSEPH NODDER
of the same place, Ironworks Mauager, 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 provide boiler furnaces or flues in which the
beating effect is improved by reason of the distance from fire to water being less
than hitherto in corrugated sections, the circulation of water being also improved
whilst great strength against collapse from high working pressures is secured.
The accompanying drawing is a longitudinal section of part of a boiler furnace or
The furnace or flue according to
flue formed in accordance with this invention.
this invention is formed of a longitudinal section presenting waved, or curved lines
entirely without flat or plain portions, the curves being so arranged that long or
sweeping curves A of large radius alternate with narrower curves B of less radius,
the said curves being all arranged so that their concavities are presented to the
water side of the furnace or flue (the upper side, in the drawing) and their
convexities are presented to the fire side of the furnace or flue (the lower side in
the drawing). The furnace or flue thus presents on the water side, alternating

page_text: depressions of long and short radius (A. B) which are joined by short curved
projecting portions C.
Having now particularly described and ascertained the nature of our invention
and in what manner the same is to be performed we declare that what we
claim is:-
A boiler furnace or flue formed with corrugations arranged as hereinbefore
described and illustrated by the accompanying drawing.
