PROVISIONAL SPECIFICATION left by the said Joseph Lamb at
the Office of the Commissioners of Patents, with his Petition, on
the 31st May 1873.
I, JOSEPH LAMB, of the City of Manchester, in the County of Lan-
5 caster, Mill Owner, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN APPARATUS OR ARRANGEMENTS FOR FEEDING, HEATING,
AND CIRCULATING WATER IN STEAM BOILERS, AND FOR BURNING LIQUID AND
GASEOUS FUELS IN COMBINATION WITH SOLID FUELS IN STEAM BOILER AND OTHER

page_text: FURNACES, AND THEREBY ECONOMISING FUEL AND PREVENTING SMOKE,” to be as
follows:-
My Invention consists of the apparatus and arrangements described
below. The feed water is brought direct from the pump or from a
cistern or an injector, and if desired through an economizer by a pipe
which communicates with the lower part of one end of the boiler. In
this pipe there are two taps (designated a and 6) and a valve (c) which
will open to water from the boiler, but close against water in the opposite
direction. Between the taps (a and b) there is a branch pipe at the front
of the furnace, passing into and on one side of the furnace to about the
fire-bridge, then across to the other side of the furnace, and back to the
front of the furnace, then into a branch in which there is a valve (d)
which will allow the water and steam to pass from the furnace, but will
close against its passage in the opposite direction. This latter branch
joins a pipe that descends to the lower part of the boiler, and ascends to
the upper part of the boiler above the water level. In the latter pipe
there is a tape (e) above, and another tap (f) below the valve (d). When
the tap (a) is open the feed water can pass through the pipes that enter
the furnace and into the boiler, but when the tap (a) is closed the pipes
in the furnace will be supplied from the boiler, the water from which
will pass from the boiler through the valve (c) and tap 6 and valve d,
and will either ascend or descend the pipe to the boiler passing through
the tap (e) or f, or both back into the boiler, thus keeping up a constant
circulation. In the centre of the water pipe that enters the furnace a
small pipe is fixed, that is continued into that part of the pipe which
crosses over the furnace, and from this part of the inner pipe several
branches are made to come to the exterior of the surrounding water pipe,
the termination of each branch forming a burner having its outlet
towards the furnace door. The central pipe communicates with the
liquid or gaseous fuel supply, the discharge of which into the pipe is
regulated by a tap, and this inner pipe has also steam introduced into it,
also regulated by a tap; the steam and liquid fuel pass along to the
burners, and is ignited by the coke or other burning fuel on the fire-bars
of the furnace.

page_text: the interior of the boiler, or the fluid or gaseous fuel may be brought
through the interior of the boiler directly to burners projecting from the
furnace side of the boiler.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Lamb in the Great Seal Patent Office
on the 26th November 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
LAMB, of the City of Manchester, in the County of Lancaster, Mill
Owner, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirty-first day of May, in the year
of our Lord One thousand eight hundred and seventy-three, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Joseph Lamb, Her special license that
I, the said Joseph Lamb, my executors, administrators, and assigns,
or such others as I, the said Joseph Lamb, my executors, adminis-
trators, 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 APPARATUS OR ARRANGE-
MENTS FOR FEEDING, HEATING, AND CIRCULATING WATER IN STEAM Boilers, and
FOR BURNING LIQUID AND GASEOUS FUELS IN COMBINATION WITH SOLID FUELS IN
STEAM BOILER AND OTHER FURNACES, AND THEREBY ECONOMIZING FUEL AND PRE-
VENTING SMOKE," upon the condition (amongst others) that I, the said
Joseph Lamb, by an instrument in writing under my hand and seal,
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
calender months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Joseph Lamb, do hereby declare
the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and

page_text: say) :-
My Invention consists of the apparatus and arrangements described
below and illustrated by Fig. 1, a view of the front of a boiler with one
internal flue; Fig. 2, a longitudinal section of part of the furnace end of
the boiler; Fig. 3, a plan section thereof; and Fig. 4, details drawn upon
an enlarged scale. The feed water is brought direct from the pump or
from a cistern or an injector, and, if desired, through an "economizer'
by a pipe (9) which communicates with the lower part of one end of the
boiler (h). In this pipe (g) there are two taps designated (a and b) and
a valve (c) which will open to water from the boiler but close against
water in the opposite direction. Between the taps a and b there is a
branch pipe (i) at the front of the furnace passing into and on one side
of the furnace to about the fire-bridge (w), then across to the other side
of the furnace and back to the front of the furnace, then into a branch
pipe (j) in which there is a valve (d) which will allow the water and
steam to pass from the furnace but will close against its passage in the
opposite direction. This latter branch (j) joins a pipe (k) that descends
to the lower part and ascends to the upper part of the boiler above the
water level. In the latter pipe (%) there is a tap (e) above and another
tap (f) below the level of the valve (d). When the tap (a) is open
the feed water can pass through the pipes that enter the furnace and
into the boiler, but when the tap (a) is closed the pipes in the furnace
will be supplied from the boiler, the water from which will pass from the
boiler through the valve c and tap 6 and valve d, and will either ascend
or descend the pipe (k) to the boiler passing through the tape or f, or
both back into the boiler, and thus keeping up a constant circula-
tion. The steam generated during the circulation will ascend the pipe k.
In the centre of the water pipe (2) that enters the furnace a small
pipe is fixed, that is continued into that part of the pipe (i) which
crosses over the furnace, and from this part of the inner pipe / several
branches are made to come to the exterior of the surrounding water
pipe i, the termination of each branch forming a burner m having its
outlet towards the furnace door. The central pipe 7 communicates with
the vessel, cistern, or gasometer which contains the liquid or gaseous fuel
supply, the discharge of which into the pipe is regulated by a tap. The
steam and liquid fuel pass along to the the burners and is ignited by
the coke or other burning fuel on the bars x of the furnace.

page_text: In Fig. 4 the details of the water, oil, steam and jet or burner pipes
are shewn. The liquid or gaseous fuel descends the pipe which has a
tap on it to regulate the supply. This pipe is screwed tightly through
the water pipe i into a T coupling. The steam pipe n has also a tap n¹
to regulate the supply of steam, and this pipe also screws through the
water pipe into the T coupling. The pipe forms either a steam or
fluid or gaseous fuel pipe, or the two combined, the steam and fuel
passing along the pipe to the burners (m), which may be one or more as
desired. The burners are screwed tightly through the water pipe i and
into a T coupling on the pipe i. The pipe i may rest upon the bridge w
at one end or upon hollow feet that stand on the fire-bars, the water
being made to circulate through the feet. The arrows upon the Figures
of the Drawings show the direction in which the fluids pass as above
explained.
If desired, a water pipe may be connected directly to the bottom of
the boiler and made to communicate with the water space and the fluid
or gaseous fuel, and steam may be brought to it by a pipe passing
through the interior of the boiler, or the fluid or gaseous fuel may be
brought through the interior of the boiler directly to burners projecting
from the furnace side of the boiler, as illustrated by Fig. 5, a cross
section; and Fig. 6, a longitudinal section; y, furnace or flue; m, three
burners screwed through the top of the flue into a pipe i inside the
boiler, which pipe passes out of the boiler to communicate with the
liquid or gaseous fuel supply. In connection with the pipe i there is
another pipe n which is screwed to a tap n' fixed in the end of the boiler.
When the tap is turned on the steam can pass through a hole in the
side of the casing and plug, and through the axis of the plug to the
pipe n.
In furnaces not used for heating water or generating steam the liquid
or gaseous fuel is conveyed to burners at the bridge part of the furnace
to throw the jets backwards from the bridge by pipes which are sur-
rounded by water pipes as above explained in reference to Figs. 1, 2, 3,
and 4, and such water pipes are made to communicate with the upper
and lower parts of a small boiler kept supplied with water to circulate
through the pipes, the steam generated during such circulation being
used for supplying the liquid or gaseous fuel pipe with steam, the
requisite quantity of steam being generated by exposing a greater or
less length of water pipe to the heat of the furnace as found necessary.

page_text: I have now particularly described the nature of my said Invention and
the mode of carrying it into effect, and claim as my Invention,-
Firstly. The combination and arrangement of water pipes and liquid
or gaseous fuel and steam pipes for burning such fuels in combination
with solid fuels in steam boiler and other furnaces substantially as herein-
before described and illustrated by the accompanying Drawings.
Secondly. The burning of liquid or gaseous fuels by taking the pipes
for supplying the fuel and steam through the boiler, substantially as
herein-before described and illustrated by Figs. 5 and 6 of the accom-
panying Drawings.
In witness whereof, I, the said Joseph Lamb, have hereunto
set my hand and seal, this Twenty-fourth day of November, in
the year of our Lord One thousand eight hundred and seventy-
three.
