City of London, Kitchen Range Manufacturer, for the Invention
of "IMPROVEMENTS IN THE CONSTRUCTION OF CLOSE OR OPEN FIRE KITCHEN
AAMA
PROVISIONAL SPECIFICATION left by the said John Lake at the
Office of the Commissioners of Patents, with his Petition, on the
5th March 1873.
I, JOHN LAKE, of 68%, Leadenhall Street, in the City of London,
Kitchen Range Manufacturer, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN THE CONSTRUCTION OF CLOSE OR OPEN
FIRE KITCHEN RANGES, APPLICABLE TO FURNACES, STATIONARY, AND LOCOMOTIVE
ENGINES," to be as follows, that is to say :—
This Invention has for its object the construction of cooking ranges
in an improved manner, and comprises a simplified arrangement for
saving fuel, and simplyfying the construction of flues for the fire gases,

page_text: which dispenses with the difficulties of cleaning, and the multiplicity of
regulating appliances required in very many of the ranges hitherto
made, also improved arrangements for heating ovens, which obviates
and avoids dust, soot, &c., and filling up the flues with soot.
The capabilities of using the range as an open or close fire at pleasure
without inconvenience by a lifting or sliding register.
In this improved range the fire is placed within about seven inches of
either right or left hand side of range, and requires no flues to heat the
boilers. An ell boiler for supply and high pressure boiler, which acts as
fire-lump either for bath or steaming purposes. Two ovens are placed on
one side of fire in some of the ranges and one only in others, the heat rays
pass from the fire under the hot plate, thence up the right or left hand
vertical flues through a damper or dampers when not shut off by valve,
thence round far end with a valve and revolving fan placed at or about
the top corner of or in any desired position in flues, thence along the
wholo under surface of oven or ovens and boiler without any guard
obstructing same, and which are worked in no other range hitherto
produced.
By this Invention the flues are so contracted and constructed in
conjunction with the valve, fan, and damper, so that the blast is carried
entirely under the ovens, so that the blast is carried entirely under the
ovens, hence no chance is given for the heat rays being checked; con-
sequently no soot is allowed to accumulate (the carbon being entirely
absorbed) in either of the flues, so that in fact this range entirely or
nearly so consumes its own smoke, hence combustion is more perfect
than in any other cooking apparatus hitherto made.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said John Lake in the Great Seal Patent Office on
the 5th September 1878.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN LAKE
of 68, Leadenhall Street, in the City of London, Kitchen Range
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifth day of March, in the year of our

page_text: Fourthly. Two ovens are placed on one side of the fire in some of the
ranges and one only in others, the heat rays pass from the fire under
the hot plate, thence up the right or left hand vertical flue, through a
damper or dampers, when not shut off by valve, thence round the far
end with a valve and revolving fan placed at or about the top corner 5
or in any desired position in flucs, thence along the whole under surface
of the oven or ovens and the boiler without any guard obstructing same,
and which are worked in no other range hitherto produced.
Fifthly. By this Invention the flues are so contracted and constructed in
conjunction with the valve, fan, and damper, so that the blast is carried 1
entirely under the ovens, hence no chance is given for the heat rays
being checked; consequently no soot is allowed to accumulate (the
carbon being entirely absorbed) in either of the flues, so that in fact this
range entirely or nearly so consumes its own smoke, hence the
combustion is more perfect than in any other cooking apparatus 1
hitherto made.
Sixthly. This Invention, viz., the valve, blast, revolving fan, and
damper, is applicable to all furnaces, stationary, and locomotive engines,
for the special object of consuming smoke.
Having now described the nature of my said Invention, what I claim 2
is the working of the fan or fans and valve in a horizontal, vertical, or
any other position in a flue or flues of engine boiler furnaces, stationary
or locomotive, and all kinds of close fire kitchen ranges, for the purpose
of consuming the whole of the carbon, smoke, and other matters arising
from the combustion of coal, coke, or other fuel, which has never here- 2
tofore been known, thereby effecting a great saving in the consumption
of such fuel.
In witness whereof, I, the said John Lake, have hereunto set my
TAM 1
of such fuel.
In witness whereof, I, the said John Lake, have hereunto set my
hand and seal, this Fifth day of September, in the year of
our Lord One thousand eight hundred and seventy-three.
