PROVISIONAL SPECIFICATION.
Improvements in the Regenerators of Furnaces.
I, HENRY SIMMONDS, C.E., F.C.S., of Colne, in the County of Lancaster, Gas
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention has for its object the construction of the regenerators of
furnaces especially applicable to the heating of gas retorts with greater sim-
plicity, efficiency and economy.
The invention consists essentially in the construction of the regenerators with
a division wall self contained which divides the air flues from the waste gas flues,
the horizontal tiles or bricks which form the air and waste gas flues abutting
thereon.
The air flues are formed of a number of horizontal zig-zag passages built in
brick or tiles which butt against the division wall but do not enter the same.
The gas flues are formed in a similar manner to the air flues spaces being left
between the horizontal bricks or tiles for the breaking up of the waste gases on
the downward flow to the main flue.
The division wall being self contained allows of a free expansion and con-
traction and also ensures a perfectly tight division wall between the air and
the waste gas flues, thus reducing to a minimum the evils of short circuiting.
The air supply is admitted at the front of the setting, travels upwards by the
zig-zag passages, becomes highly heated by contact with the division. wall, then
entering suitable passages passing over the crown of the "producer, burns with
the gas issuing from the nostrils of the producer, the products of combustion
circulate round the retorts and afterwards enter the waste gas flue of the re-
generator through suitable openings, then pass in a downward direction to the
main flue.

COMPLETE SPECIFICATION.
Improvements in the Regenerators of Furnaces.
I, HENRY SIMMONDS, C.E., F.C.S., of Bury, in the County of Lancaster, late of
Colne, in the County of Lancaster, Gas Engineer, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement:—
This invention has for its object the construction of the regenerators of
furnaces especially applicable to the heating of gas retorts with greater sim-
plicity, efficiency and economy.
The invention consists essentially in the construction of the regenerators with
a division wall self contained which divides the air flues from the waste gas flues.

page_text: the horizontal tiles or bricks which form the air and waste gas flues abutting
thereon.
The invention will be fully described with reference to the accompanying
drawings;
Fig. 1. Cross section through regenerator and one set of retorts.
Fig. 2. Longitudinal section through the waste gas flues.
Fig. 3. Longitudinal section through the air supply flues (regeneration of the
air).
The grate A the producer B the combustion chamber C and the retorts C¹
are constructed and set in the usual way.
Between the air inlet flues D and the waste gas exhaust flues E which lead to
the main flue F I build a division wall G which is self contained.
The air inlet flues D through which the supply of fresh air passes are formed
of a number of horizontal zig-zag passages d built of bricks or tiles H which abut
against one side of the division wall & but do not enter or join into the same
leaving both the horizontal division walls H and the vertical division wall G
free to contract or expand without one acting upon or interfering with the free
action of the other.
The waste gas exhaust flues E are formed in a similar manner to the air flues
horizontal passages being formed by the divisions K of brick or tiles for the
breaking up of the waste gases on the downward flow as indicated by the arrows
to the main flue F. The horizontal divisions K are built against but not into
the vertical division G leaving both free to contract or expand.
The vertical division wall G being thus self contained permits of a free expan-
sion and contraction and also ensures a perfectly tight division wall between
the air flues 1 and the waste gas flues E thus reducing to a minimum the evils
of short circuiting.
The air supply is admitted at M at the front of the setting, travels upwards
by the zig-zag passages d, becomes regenerated or highly heated by contact with
the vertical division wall G, then enters suitable passages & passing over the
crown b of the producer B burns with the gas issuing from the nostrils of
the producer B, the products of combustion circulate round the retorts C¹ and
afterwards enter the waste gas flue E of the regenerator through suitable openings,
then pass in a downward direction as indicated by the arrows to the main flue F
giving up their heat as they flow to the vertical division wall G from which the
heat is transferred to the inflowing air.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. A regenerative furnace constructed with a division wall between air inlet
flues and the waste gas exhaust flues independent of the horizontal divisions of
the said flues but against which the horizontal divisions abut without being built
into or entering it substantially as and for the purpose described.
2. A regenerative furnace constructed with the horizontal divisions of the air
inlet flues and the waste gas exhaust flues abutting against but not entering into
the vertical division between them to admit of free expansion and contraction
substantially as described and shown.
3. A regenerative furnace having the air inlet flues and the waste gas exhaust
flues constructed or formed substantially as described and shown.
