Improvements in Regenerator Settings.
I, JOHN WILSON BROADHEAD, of Messrs. Robert Dempster and Son, Limited,
of Rose Mount Iron Works, Elland, in the County of York, Gas Engineers, do
hereby declare the nature of this invention to be as follows:
My invention has reference to regenerator settings and consists in placing
between the secondary air and waste heat flues, instead of the ordinary flat tile
or bricks usually employed, a corrugated or fluted tile whereby the efficiency
of the recuperation of heat is greatly improved. In constructing a tile according
to my invention for the aforesaid purpose, I preferably form the said tile for
say a few inches all round, straight or flat, and the middle of the said tile I
form corrugated or fluted, the corrugations being formed somewhat after the
manner of a panel in the centre of the tile. Owing to the increased strength
gained by corrugation, I am enabled to make the corrugated centre much thinner
than the tiles hitherto employed for the purpose and the flat or plain edging formed
around the tile enables good, firm joints to be made.
Dated this 26th day of August 1899.

Improvements in Regenerator Settings.
I, JOHN WILSON BROADHEAD, of Messrs. Robert Dempster and Sons, Limited,
of Rose Mount Iron Works, Ellaud, in the County of York, Gas Engineers, 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 follow-
ing statement:-
My invention has reference to the division walls of flues in regenerator furnaces
or settings, and consists in placing between the secondary air and waste heat
flues, instead of the ordinary flat tiles or bricks usually employed, corrugated
or fluted tiles, whereby the efficiency of the recuperation of heat and the working
of the setting are greatly improved.
In constructing a tile according to my invention for the aforesaid purpose, I
preferably form the said tile for, say, a few inches all round, straight or flat,
and the middle of the said tile I form corrugated or fluted, the corrugations being
formed somewhat after the manner of a panel in the centre of the tile. Owing
to the increased strength gained by corrugation, I am enabled to make the
corrugated centre much thinner than the tiles hitherto employed for the purpose

page_text: and the flat or plain edging formed around the tile enables good, form, joints to
be made.
In the accompanying drawings:-
Fig. 1 is a sectional plan, taken on line A B Fig. 2, of a fragment of a
division wall built or formed of my improved special construction of tiles or
bricks;
Fig. 2 is elevation of Fig. 1; and
Fig. 3 is a perspective view of part of a regenerator furnace shewing oue
way of applying my improved corrugated tiles to divide the waste heat flues
and air passages.
The tile or brick, represented at a, is made flat or plain for a short distance
from each outer edge towards the middle on both sides to form wide margins,
mouldings, or frame portions a¹ on the two faces of the tile, and the portion of
the tile within or surrounded by said mouldings or frame portions is corrugated
or fluted on both faces, as at a³, the increased strength gained by the corruga-
tions enabling the said middle portion of the tile to be made much thinner than
the tiles or bricks hitherto employed for the same purpose, whereby heat is more
rapidly conducted from side to side of the tile or brick, while the corrugations
largely increase the surface areas for the absorption or collection and radiation
of heat.
The plain or flat surrounding, moulding, or framing a¹ enables good firm joints
to be made.
At the edges or sides where the tiles are intended to join each other, rebates
may be formed to make rebated joints between each tile as shewn on the drawings;
or said edges or sides may be made straight to form flush joints or tongued or
grooved, as may be desired.
The specially constructed tiles or bricks are joined together in the ordinary
way, as shewn, to build or form the walls for dividing the waste heat flues from
the secondary air passages, and when there are two waste heat flues with a
secondary air flue sandwiched between them, I employ the corrugated tiles to
form the division walls on each side of the secondary air flue as illustrated at
Fig. 3. Used in this way the corrugated tiles enable a very efficient shallow
regenerator to be constructed.
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 special construction of tile or brick for use in building or forming the
walls dividing secondary air and waste heat flues in regenerator furnaces, said
brick having plain or straight outer portion or surrounding edges or mouldings
and a corrugated or fluted middle portion substantially as herein set forth and
shewn on the drawings.
