SAMUEL RICHARD SMYTH, Managing Director of the Standard Iron and Steel
Company, Limited, Manchester, in the County of Lancaster. IMPROVEMENTS IN
CONSUMING THE SMOKE AND OTHER WASTE PRODUCTS OF COMBUSTION AND IN
THE APPARATUS EMPLOYED THEREFOR, SUCH IMPROVEMENTS BEING APPLICABLE TO
BOILER AND OTHER FURNACES OR HEATING APPARATUS."
:
This Invention has for its object not only an improved method of consuming and
utilizing the smoke and other waste products of combustion evolved from boiler
and other furnaces and fire places, but also the effecting an immense economy of
fuel by the utilisation of such waste products and the total avoidance of the
injurious and inconvenient effects hitherto arising therefrom. To effect such object
I proceed as follows:-I arrange a series of wrought-iron flanged tubes in such a
manner that they communicate from one fire-box to another of a double-flued
Lancashire or other similar form of boiler; or where there are a combination of fire-
boxes, as in marine boilers, from one fire-box to another throughout the series.
Such tubes are rivetted or otherwise properly secured between fire-box and fire-box
in such a position that the lower part of cach tube is about level with the top of
the fire-bars. These tubes, which I shall hereafter call fire-tubes, serve to convey
the smoke and other products of combustion from one fire to the adjoining or con-
tiguous fire, whereby the smoke and other waste products of combustion evolved
while feeding one fire-box are caused to pass over the incandescent fire in the
adjoining fire-box, thereby becoming not only thoroughly utilised, but almost com-
pletely consumed, thus obviating both the inconvenience and injury hitherto

is being fed so that the waste products of combustion evolved have no other outlet
than the fire-tubes before mentioned, which as before described serve to conduct
them over the incandescent fire of the adjoining furnace.
My Invention may also be applied with advantage to furnaces employed for the
purpose of warming buildings, ovens, and other similar heating apparatus where
more than one furnace is employed.
A suitable automatic arrangement, by which the damper of one fire-box when
opened may shut the damper of the other or adjoining one, may also be combined
with the above Invention if desired.
SPECIFICATION in pursuance of the conditions of the Letters Patent and of
an Order of the Lord Chancellor filed by the said Samuel Richard Smyth in
the Great Seal Patent Office on the 13th October 1877.
SAMUEL RICHARD SMYTH, Managing Director of the Standard Iron and Steel
Company, Limited, Manchester, in the County of Lancaster. "IMPROVEMENTS IN
CONSUMING THE SMOKE AND OTHER WASTE PRODUCTS OF COMBUSTION AND IN
THE APPARATUS EMPLOYED THEREFOR, SUCH IMPROVEMENTS BEING APPLICABLE TO
BOILER AND OTHER FURNACES OR HEATING APPARATUS."
This Invention has for its object an improved method of consuming and utilizing
the smoke and other waste products of combustion evolved from boiler and other
furnaces and fire-places. I arrange a series of flanged tubes in such a manner that
they communicate from one fire-box to another of a double-flued Lancashire or
other form of boiler used on land, or where there are a combination of fire-boxes, as
in marine boilers, from one fire-box to another throughout the series. Such tubes
are rivetted or otherwise properly secured between fire-box and fire-box, in such a
position that the lower part of each tube is about level with the top of the fire-
bars. These tubes, which I shall hereafter call " fire-tubes," serve to convey the
smoke and other products of combustion from one fire to the adjoining or conti-
guous fire, whereby the smoke and other waste products of combustion evolved
whilst feeding one fire-box are caused to pass over the incandescent fire of the
adjoining fire-box, thereby becoming not only thoroughly utilized but almost
completely consumed. This I effect by closing the damper of the fire-box, which is
being fed so that the waste products of combustion evolved have no other outlet
than the fire-tubes before mentioned through which they are conveyed over the
incandescent fire of the adjoining furnace.
A suitable automatic arrangement, by which the damper of one fire-box when
opened may be made to close the damper of the other or adjoining one, may also be
combined with the above Invention if desired.
And in order that my said Invention may be better understood and more readily
carried into effect, I will now, with the aid of the accompanying Drawings, whercon
similar letters of reference indicate corresponding parts, proceed to more particularly
describe and ascertain the same.
:
Figure 1 of such Drawings shews a transverse vertical section of a double-flued
Lancashire boiler with my improvements applied thereto. Figure 2 shows the
same in longitudinal section; and Figure 3 shews a plan thereof."
As in the ordinary arrangement of this form of boiler the boiler shell a has extend-
ing throughout its length two parallel flues b, each fitted with furnaces c, the bars of
which furnaces I prefer to be of the kind known as Smyth's oxygen bar. A suit-
able fire-bridge & of any well-known construction is placed in any convenient
position. Each of the flues b is fitted with a damper, actuated at proper intervals
either manually or automatically, so as to prevent the escape of the products of
combustion through the up-take flue.
.
In order to provide for the more efficient and complete combustion of the inflam-

page_text: mable matters evolved from the furnaces, the duplex flues b are connected by a
series of fire-tubes e, which thus form a system of tubular openings f uniting one
flue with the other. I flange such fire-tubes at their junctions with the flues in
any convenient manner, in accordance with the form of the flues themselves, and I
then rivet or otherwise securely fasten such fire-tubes thereto, as is indicated in
Figure 3 of the accompanying Drawings.
The flues are fired alternately, and when one fire is highly incandescent, and thus
best adapted for igniting any inflammable matter, the damper of the adjoining flue
is closed and the fire stoked. The products of combustion immediately evolved
from the fresh fuel, as well as the air passing into the flue, are at once carried
through the fire-tubes e and brought into contact with the incandescent fuel of the
adjoining furnace, whereby the gases evolved are consumed and very little smoke is
suffered to escape.
Another important feature of my Invention is its application to marine boilers,
and when these boilers are used in vessels of war the position of such vessels will
be less discornible through the reduction of the smoke emitted from the funnel
than hitherto.
In the case of marine boilers I prefer to fix the lateral fire-tubes arranged in one,
two, or more tiers, as may be found most desirable.
At the rear end of the fire-box, where it opens into the up-take, I fit a damper
which may move upon an axis arranged below the fire-bridge. The axle is fitted
with a pair of mitre wheels, one of which is keyed on to the shaft, and the other is
attached to the damper. The free end of the shaft is furnished with a hand wheel,
crank, or other similar apparatus by which the damper can be opened or closed, and
the products of combustion thereby caused to pass into the contiguous furnace, as
herein-before explained. In place of the mitre wheels a worm and wheel may be
applied for opening and closing the damper.
Figures 4 and 5 of the accompanying Drawings illustrate this application of my
Invention, together with my improved damper arrangement, Figure 4 being a
section through the fire-boxes shewing the fire-tubes connecting the same; k is tho
damper to close the end of the fire-box; and the wheel and spindle or crank for
working the damper k, as before described.
Figure 5 shews a front view of the boiler, partly in section and partly in
elevation, wherein h, k, are the dampers, and i, i, the hand wheels for working the
same.
My Invention may also be applied to apparatus for warming buildings, ovens,
and other places where more than one furnace is used.
Having now particularly described the nature of my said Invention and the
manner of carrying the same into effect, I would have it. understood that I
claim,―
1stly. The arrangement of a series of tubes so that they communicate from one
fire-box to another of a double-flued Lancashire or other form of boiler used on
land, substantially in the manner herein-before described.
2ndly. The connecting together in marine boilers of the fire-boxes by a similar
arrangement of tubes, substantially in the manner heroin-before described.
3rdly. The arrangement of the dampers in marine boilers, substantially as herein-
before described.
4thly. I claim the application of my Invention to heating apparatus for
warming buildings, ovens, and other places where more than one furnace is
employed.
In witness whereof, I, the said Samuel Richard Smyth, have hereunto set
my hand and seal, this Twelfth day of October, in the year of our Lord One
