PROVISIONAL SPECIFICATION.
Improvements in or relating to Regenerating Furnaces.
I, JOHN BATTEN of 9 Loraine Terrace, Lemington-on-Tyne in the County of
Northumberland, Brickworks Manager do hereby declare the nature of this
invention to be as follows:--
My invention refers to improvements in or relating to regenerating furnaces and
has for its object economy in construction and greater facility in working. To
accomplish my purpose I arrange the regenerators in pairs on either side of and at
or about the same mean level as the furnace. The gas from the producers is
conducted to a flue or conduit leading alongside a similar air flue to the gas
regenerators alongside which the air regenerators are placed.
Between the furnace itself and the nearest regenerators I arrange cooling spaces
or airways boxed or lined out where necessary above which are the flues or passages
connecting the furnace with the regenerators. The latter I may provide with
duplicate exits so that if or when desired the gases issuing from the furnace may
pass either through the regenerators to the chimney or through a separate flue or
Hlues to be used either in heating boilers or in annealing arches or for any other
purpose where such heat is required. I regulate the admission or exit of the
issuing gases from the regenerators as above described by means of dampers or
valves which if desired may be connected so that the opening of one shall shut the
other and vice versa.
The gas and air are preferably kept separate in their course to and through the
entering regenerators nor do they meet one another until the furnace is reached
where the impinging currents commix and are burnt issuing thence as above
described. The air regenerators when placed outside or further from the furnace
than the gas regenerators may be carried higher up so that the heated air issuing
therefrom may pass through Hues leading downwards to the furnace at a somewhat
higher level than the gas flues which enter thereunder.
The furnace bottom may be concave or troughed for melting purposes or level for
a heating furnace access thereto for charging cleaning repairing and other purposes
being had in the usual way. Great economy in construction and facility in working
can thus be obtained.

COMPLETE SPECIFICATION.
Improvements in or relating to Regenerating Furnaces.
I, JOHN BATTEN of 9 Loraine Terrace, Lemington-on-Tyne in the County of
Northumberland, Brickworks Manager 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 :-
My invention refers to improvements in or relating to regenerating furnaces and
has for its object economy in construction and greater facility in working.
To accomplish my purpose I arrange the regenerators in pairs on either side of
and at or about the same mean level as the furnace. The gas from the producers
is conducted to a flue or conduit leading alongside a similar air flue to the gas
regenerators alongside which the air regenerators are placed. Between the

page_text: furnace itself and the nearest regenerators I arrange cooling spaces or airways
boxed or lined out where necessary above which are the flues or passages connecting
the furnace with the regenerators. The latter I may provide with duplicate exits
so that if or when desired the gases issuing from the furnace may pass either through
the regenerators to the chimney or through a separate flue or flues to be used either
in heating boilers or in annealing arches or for any other purpose where such heat
is required. I regulate the admission or exit of the issuing gases from the
regenerators as above described by means of dampers or valves which if desired
may be connected so that the opening of one shall shut the other and vice versa.
The gas and air are preferably kept separate in their course to and through the
entering regenerators nor do they meet one another until the furnace is reached
where the impinging currents commix and are burnt issuing thence as above
,.described. The air regenerators when placed outside or further from the furnace
than the gas regenerators may be carried higher up so that the heated air issuing
therefrom may pass through Hues leading downwards to the furnace at a somewhat
higher level than the gas flues which enter thereunder.
The furnace bottom may be concave or troughed for melting purposes or level for
a heating furnace access thereto for charging cleaning repairing and other purposes
being had in the usual way.
Great economy in construction and facility in working can thus be obtained.
I will fully explain my invention with reference to the accompanying drawings
in which
Figure 1 shows a section through regenerators and furnace, Figure 2 being a
sectional plan of the same arrangement.
Figure 3 is a transverse section on line A A showing the arrangement of gas and
air ports leading to or from the furnace; Figure 4 shows a cross section of the
latter on line A¹ A¹.
Similar letters or marks of reference denote similar parts in the Specification and
drawings.
Referring to the figures, 2 is the furnace to which access is had through
openings 2 in the usual way; 3, 3 and 4, 4ª represent respectively the
regenerators for gas and air or products of combustion entering to or leaving the
furnace.
Gas from producers or like sources is allowed to enter the structure at 5 and air
is similarly admitted at 5" (see Fig. 2). Ordinary reversing valves are placed at
these points so that gas entering at 5 can be made to traverse at will either gas
passage 6 or 7 and similarly air entering at 5ª can be made to traverse at will either
air passage 8 or 9.
It will be observed that I construct the regenerators at about the same mean
level as the furnace instead of below the same, the capacities of these and of the
ports for gas and air in connection therewith being (proportioned in the usual way.
Two gas ports 10 lead from each chamber 3, 3" to the furnace and three air ports Ĭ1
lead from each chamber 4, 4ª to the furnace. The gas is admitted to the
regenerators from distributing ports 12 formed underneath the floors of the
same which have openings leading up into the regenerator chambers.
Air is
similarly admitted to the regenerators from distributing ports 14 as shown in the
drawings. Access to the regenerators is easily had by openings at 16.
Cooling spaces are provided between furnace and regenerators as shown at 17,
18 being strengthening boxes built into the masonry to support the furnace.
Cooling spaces 19 are likewise provided between the air ports which are built
so as to be easily repaired and readily accessible as shown most clearly in
Fig. 3.
20 is a flue connecting the regenerators with the chimney 21 the said flue being
fitted with valves or dampers at 22, 22ª as shown in the plan.
The regenerators are shown with the checker-work set in position ready for
work.
The action of the furnace is as follows:-The reversing valves above alluded

page_text: to, determining the direction in which gas and air travel, let us assume that the
said valves have been set so as to close passages 7 and 9 when passages 6 and 8 will
be open. Gas coming from the producers then entering at 5 passes along 6 while
at the same time air enters at 5 and passes along 8.
The gas rises from ports 12 up through chamber 3 and passes down ports 10
while similarly air rises from ports 14 up through chamber 4 and passes down
ports 11. At M the gas and air commix and are burnt in the furnace 2, the pro-
ducts of combustion passing up the corresponding gas and air ports on the opposite
side of the furnace and then down through regenerators 3, 4 to ports 12 and 14
whence they find exit via damper or valve 22ª through flue 20 to chimney 21.
Under these conditions valve or damper 22 of course remains closed. On reversing
the system, the gas and air pass in the opposite direction from passages 7 and 9
through regenerators 3, 4 through furnace 2 regenerators 3, 4 and valve 22,
valve 22 being in this case closed.
It will be observed that by the arrangement shown and described, the products
of combustion are not allowed to return to the reversing valves at 5 and 5ª whereby
the life of these valves is most materially increased thus effecting a great saving in
cost of working and maintenance of furnace. Further the arrangement of furnace
and regenerators at one mean level facilitating repairs in re-arching and lining
furnaces and flues a great saving is effected by this mode of construction.
The flue 20 connecting regenerators with chimney can with advantage be used
for heating boilers or for annealing purposes.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. Constructing regenerating furnaces with the regenerators and furnace con-
nected together by gas ports 10 and air ports 11 and cooling spaces all arranged
with respect to one another and working substantially as and for the purposes
herein set forth.
2. Constructing regenerating furnaces with the regenerators at or about the same
mean level as the furnace itself so that the gas and air shall after having passed
through the regenerators and furnace have exit through a separate flue 20 leading
to a chimney (instead of returning vid the reversing valves at 5 and 5ª) substan-
tially as and for the purposes hereinbefore described and illustrated in the
accompanying drawings.
