for the Invention of "IMPROVEMENTS IN STEAM BOILERS AND APPARATUS
CONNEOMED
"
Sealed the 25th September 1863, and dated the 22nd April 1863.
PROVISIONAL SPECIFICATION left by the said Gill Bridges Barber, at the
Office of the Commissioners of Patents, with his Petition, on the
22nd April 1863.
I, GILL BRIDGES BARBER, of Park Street Boiler Works, Redbank, in the
City of Manchester, and No. 60, Stocks Street, Cheetham Hill, Manchester,
in the County of Lancaster, Boiler Maker, do hereby declare the nature of
the Invention for "IMPROVEMENTS IN STEAM BOILERS AND APPARATUS CONNECTED
THEREWITH," to be as follows:-
The nature of my Invention consists, first, in combining with a box or
chamber forming a combustion chamber, one, two, or more flues passing from
firing places situated at one end of the boiler; the firing places or flues are
by preference formed of tubes of a circular section; these tubes are contained
within the boiler, and at their back end they both open into the combustion
chamber, this chamber being situated immediately behind the bridge or bridges
of each firing place or furnace flue. I also arrange this box or combustion

page_text: chamber to lead downwards and pass out of the bottom of the boiler, and after
passing below a certain length at the bottom of the boiler, to again rise up
into the boiler, so forming a second combustion box within the boiler; it then
passes out at the back of the boiler, and the products of combustion are then
led back along each side of the boiler, and at the front of the boiler they are
led downwards, and then along the under side of the boiler to the chimney.
In each combustion chamber are placed tubes, against which the flames in the
combustion chamber impinge; these tubes open at each end into the boiler.
The tubes are at an angle inclining upwards, and are fixed to the top and
bottom of the box or combustion chamber. Where the combustion chamber
passes out of the bottom of the boiler, and again rises up into it, it is contracted
to or nearly to the size of the flue or flues from the firing places.
By combining two or more firing places or flues with a combustion chamber,
as above described, and by supplying the firing places with fuel at different
times, the smoke passing from the firing place last supplied with fuel will be
brought in contact with the flames from the other firing place or places, thus
causing a more complete combustion of the fuel.
Another part of my Invention consists in placing a tubular feed water
heater between the downtake of the first box or combustion chamber and the
uptake or second box or combustion chamber. The flame thus passes through
the first box or combustion chamber, and then through the tubes of the tubular
box or feed water heater to the uptake box connected with the hinder flue or
flues of the boiler.
Another part of my Invention in steam boilers consists in placing a firing
flue or flues at cach end of the boiler, and such flue or flues having a separate
box or combustion chamber with inclined tubes in each box, as before
described. The flame impinging against the inclined tubes in each box or
combustion chamber as it passes to the under side of the boiler into a flue
space, and passing through tubes on each side of the boiler at right angles
with the boiler, forming a feed water heater, with a water space midfeather or
of brick. The flame continued to and along each side of the boiler to each
end, and dipping and following along the under side of the boiler, and passing
to the outlet on one side of the boiler to the chimney.
Another part of my Invention in steam boilers consists in extending the
circumference of the boiler in any convenient part of its length, and in a
portion of this extended part of the circumference tubes are placed; these
tubes are surrounded with water, and through them the products of combustion
from the furnace are led, the products of combustion being for this
purpose first
led into an open space at one one end of the extended part of the boiler, from
.

page_text: which they pass through the tubes into another portion of the extended part
of the boiler that is in connection with an uptake that leads to a suitable
outlet.

by the said Gill Bridges Barber in the Great Seal Patent Office on the
22nd October 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GILL
BRIDGES BARBER, of Park Street Boiler Works, Red Bank, in the City of
Manchester, and No. 60, Stocks Street, Cheetham Hill, Manchester, in the
County, of Lancaster, Boiler Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of April, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-sixth year of Her.
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Gill Bridges Barber, Her special licence that I, the said Gill Bridges
Barber, my executors, administrators, and assigns, or such others as I, the said
Gill Bridges Barber, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN STEAM.
BOILERS AND APPARATUS CONNECTED THEREWITH," upon the condition (amongst
others) that I, the said Gill Bridges Barber, my executors or administrators,,
by an instrument in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same to be
filed in the Great Seal Patent Office within six calendar months next and
immediately aftor tho date of the said Letters Patent.
NOW KNOW YE, that I, the said Gill Bridges Barber, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
Figure 1 of the annexed Drawings shews a vertical section of a boiler,
constructed according to the first part of my Invention; Figure 2 is a hori
zontal section, and Figure 3 a transverse section of the same...
.
:. My Invention consists, first, in combining with a box or chamber a forming

page_text: a combustion chamber, one, two, or more flues b, b, passing from firing places
6, 61, situated at one end of the boiler; the firing places or flues are, by
preference, formed of tubes of a circular section; these tubes are contained
within the boiler, and at their back end they both open into the combustion
chamber a;
this chamber being situated immediately behind the bridge or
bridges c, c, of each firing place or furnace flue. I also arrange this box or
combustion chamber to lead downwards and pass out of the bottom of the
boiler at a', and after passing below a certain length of the bottom of the
boiler to again rise up into the boiler at d, so forming a second combustion
box within the boiler, it then passes out by flues e, e, at the back of the boiler,
and the products of combustion are then led back along each side of the
boiler by passages f, f, and at the front of the boiler they are led downwards
and then along the fluo g, the under side of the boiler to the chimney. In
each of the combustion chambers a and d are placed tubes h, against which
the flames in the combustion chamber impinge; these tubes open at each end
into the boiler; the tubes are placed at an angle inclining upwards or
otherwise, and are conveniently fixed to the top and bottom of the box or
combustion chamber, where the combustion chamber a passes out of the
bottom of the boiler, and again rises up into it at d; the passage is contracted
to or nearly to the size of the flue or flues from the firing places. By com-
bining two or more firing places or flues with a combustion chamber, as above
described, and by supplying the firing places with fuel at different times, the
smoke passing from the firing place last supplied with flul will be brought in
contact with the flames from the other firing place or places, thus causing
a more complete combustion of the fuel.
Figure 4 is a longitudinal section, Figure 5 a transverse section, and
Figure 6 a horizontal section of a boiler constructed according to another part
of my Invention. This part of my Invention consists in placing a tubular
feed water heater i between the downtake of the first box or combustion
chamber a, and the uptake or second box or combustion chamber d. The
flame thus passes through the first box or combustion chamber a, and then
through the tubes of the tubular box or feed water heater i to the uptake
box d connected with the hinder flue or flues e of the boiler.
Figure 7 is horizontal section, Figure 8 a vertical section, and Figure 9
a transverse section of a boiler, constructed according to another part of my
Invention. This improvement in steam boilers consists in placing a firing
flue or flues at each end of the boiler, and such flue or flues having a
separate box or combustion chamber a with inclined tubes h in each box, as
before described. The flame impinges against the inclined tubes in each box

page_text: or combustion chamber as it passes to the under side of the boiler into a flue
space, and then passes through tubes at i, i, on each side of the boiler at right
angles with the boiler, these tubes and their casing forming a feed water heater
with a midfeather ', which may cither be water space or brick. The flame
is conducted along each side of the boiler by passages f, f, to each end, and
then dips down and follows along the under side of the boiler by the flues g, g,
and passes to the outlet k on one side of the boiler to the chimney.
Figure 10 is a side view, Figure 11 a transverse section, and Figure 12 a
plan of a boiler, constructed according to another part of my Invention. This
improvement in steam boilers consists in extending the circumference of the
boiler in any convenient part of its length, and in a portion of this extended
part of the circumference tubes are placed; these tubes are surrounded with
water, and through them the products of combustion from the furnace are led,
the products of combustion being for this purpose first led into an open
space m at one end of the extended part of the boiler, from which they pass
through the tubes into another portion n of the extended part of the boiler
that is in connection with an uptake o that leads to a suitable outlet.
Boilers of this construction may be made single, if desired, in place of double,
as shewn; the extended portion of the circumference of the boiler is put in
communication with the interior of the boiler by holes or passages formed
through the inner skin.
In witness whereof, I, the said Gill Bridges Barber, have hereunto set
my hand and seal this Twenty-first day of October, in the year of our
Lord One thousand eight hundred and sixty-three.
GILL BRIDGES BARBER. (L.S.)
