We, ALEXANDER MORTON of 241 West George Street Glasgow, Lanarkshire,
Engineer, and JOHN FYFE of 7 West George Street, Glasgow aforesaid, Mineral
Oil Manufacturer, do hereby declare the nature of this invention to be as follows:-
:-
This invention has for its object to economise fuel and consume smoke in the
distilling and boiling of mineral oils where the furnaces are heated and cooled
alternately, and it consists in forming and using one or more flue passages so
arranged and governed by dampers or valves, that any proportion of the heated
air in passing through the hotter furnaces may be transferred to the colder furnaces,
on the well known regenerative principle. Two or more furnaces may form a
series, and the stills or oil boilers may be built in a row with one main return flue
extending throughout their whole length, with outlet and inlet flue branches com-
municating with each furnace. These branch flues may each be fitted with a
damper or valve so adjusted that any number of the outlet branch flues from the
hotter or cooling furnaces may be full open to the main return flue whilst the
inlet branch flues may be adjusted full open for quick distillation or boiling, or
to any degree of opening for slower distillation or boiling. The invention is
applicable whether the fuel used be solid, liquid or gaseous the same being employed
on the regenerative principle before described or so that the transferred heated air
may pass in with or through the fuel and thereby assist combustion, or the
transferred hot air may be used to raise the temperature of the cooler or "green
furnaces before any fuel has been used. It is preferred that these furnaces be
fitted with ash pit doors which can be opened in cooling down, and closed while
heating up, and it will be understood that in applying the regenerative method
before described to these furnaces the flues for conducting the escape gases to the
chimney may be shut or opened as required, as practised with other regenerative
furnaces,

Mineral Oils.
We, ALEXANDER MORTON of 241 West George Street, Glasgow, Lanarkshire,
Engineer, and JOHN FYFE of 7 West George Street, Glasgow aforesaid, Mineral
oil Manufacturer, 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 :-
This invention has for its object to economise fuel and consume smoke in the
distilling and boiling of mineral oils where the furnaces are heated and cooled
alternately and it consists in forming and using in addition to the ordinary flue
leading to the chimney other flues or passages so arranged and governed by
dampers or valves that any proportion of heated air after passing through the
hotter furnaces may be transferred or conducted to the colder furnaces or the well
known regenerative principle.
Figure 1, illustrates partly in elevation and partly in longitudinal vertical
section the application of the invention to furnaces for the distillation of mineral
oils. Figure 2 is a transverse section of the arrangement whilst figure 3 is in part
a horizontal section on the line A - - - -.- B figure 2, and in part a horizontal
section on the line C - D figure 2.
As shewn by these figures there is provided in addition to the flue E, leading to
the chimney and communicating by branch flues F, and ports a, with the
furnaces G, underneath the stills H, another flue I, which has a branch flue J, for
each furnace the said branches having ports b, leading into the ashpits or the
spaces below the fire bars K, of the furnaces.
The branch flues J, are each provided with dampers or valves c, by raising or
lowering which communication between the branches and the return flue I, is made
or cut off as desired, and direct communication between the furnaces G, and the
flue E, is made or cut off by opening or closing the dampers d, in the branch
flues F. Above the damper or valve d, there is formed in each flue F, a branch e,
leading to the atmosphere and provided with a damper or valve f, by raising or
lowering which, communication between the furnaces G, and the outer air at that
point is made or shut off as desired.
Two or more furnaces G, may constitute a series and as shewn on the drawings
the stills are arranged in a row, although they may be otherwise built, the return
flue I, extending throughout the length of the series.
Let it be supposed that the two furnaces at the right hand side of fig. 3 are being
cooled and the two furnaces at the left hand side of the said figure are being or are
about to be heated up, then in such case the dampers d, in the flues F. leading
from the said right hand furnaces to the flue E, are closed whilst the dampers f, of
the air passages e, and the dampers e, of the branch flues J, leading to the return
flue I are opened. This has the effect of reversing the current and causing cold air
to enter the cooling furnaces G, by the branches e, and ports a, and after being
heated to pass out by the ports b, in the ashpit below the fire bars and through the
branch fines J, into the return flue I. In the other furnaces being or about to be
heated the dampers f, of the entering cold air flues e are closed, whilst the
dampers c and d, of the hot branch flues J and F, respectively are open the effect
of which is, that the air heated as set forth passes in through the porta b, and

page_text: thence up through the fire bars in the said furnaces thereby transferring the heat
from the cooling to the heating furnaces and promoting combustion in and
lessening smoke from them or the said heated air may with the like object be used
to raise the temperature of the said furnaces before any fuel is placed therein.
With a bench of stills any number of the outlet branch flues J, from the hotter
furnaces may be full open to the return flue I, whilst the dampers c, of the branch
flues J, for the time being serving as inlets for the heated air to the furnaces being
heated may be full open for quick distillation or, for slow distillation adjusted to
any degree of opening desired.
The invention is applicable whether the fuel used be solid, liquid or gaseous, and
it is preferred in any case that the furnaces be fitted with ash pit doors as indicated
at figure 1, which can be opened or closed as required.

Figure 4 illustrates in part elevation and part vertical section, the adaptation of
the invention to a bench or series of boilers for boiling mineral oils, figure 5, being
a part vertical section through a boiler and furnace at right angles to fig. 4, and
figure 6, a part plan and part horizontal section of the arrangement the left hand
end of the said figure being a horizontal section on the line W.. X, and the
right hand end a horizontal section on the line Y - Z figure 4. In these
figures the same letters of reference indicate corresponding parts to those already
referred to with regard to figures 1, 2 and 3; E, being the main flue leading to the
chimney; F, the branch flues thereto from the furnaces G; d the dampers of the
said flues, and f, the cold air dampers; J the branch flues communicating between
the furnaces and the return flue I, and c the dampers of the said branch flues.
With this arrangement when a furnace is being cooled down, the dampers d are
closed and the cold air dampers f, and dampers c in the flues J opened which has
the effect of reversing the current and causing the air to pass into the furnace
through the ports a figure 6, and flues F, thence down through the fire bars into the
ashpit and out through the ports b, and branch flues J, into the hot return flue I,
and the air thereby heated in passing through the cooling furnaces is transferred
into the furnaces being or about to be heated, through the branch flues J, and
ports b, as hereinbefore set forth with reference to figures 1, 2 and 3.
In the several modifications shewn the hot air from the return flue I, enters and
passes out alternately through ports b below the fire bars but it will be understood
that the hot air may also enter or pass out above the fire bars of the furnaces or
instead of passing through the furnaces G, it may pass through ports direct into
and from the flues F.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. In conjunction with stills for distilling, and boilers for boiling mineral oils,
the use of flues or passages communicating between two or more furnaces for the
purpose of transferring heated air, substantially as hereinbefore described and
shewn on the appended drawings.
2. In conjunction with stills for distilling, and boilers for boiling mineral oils,
the use of dampers and flues so arranged as to reverse the current and to obtain
heated air from the furnaces when cooling substantially as hereinbefore described
with reference to the appended sheet of drawings.
