do hereby declare the nature of this invention to be as follows:-
:
The improvements relate more particularly to kilns for burning lime, cement &
such like but are capable of being used for other purposes, the said improvements
consist in inaking the kiln of an inner and outer chamber of metal, one within the
other connected at top & bottom and suitably stayed to form a space intended to
hold water the chambers are perforated for doors and for inlet, outlet pipes and
manholes, they have by preference a cylindrical shape on plan with a domed top
of brick having an aperture therein for feeding and for passage of the products of
combustion; also blow off cocks and safety valves are supplied-The bottom of
the kiln is made of brick or fire clay conical or rising to the centre so that the
material falls towards the doors, which are at a low level, ready for delivery-The
outer chamber may be covered or encased in brick or jacketted with any suitable
material On the kiln being charged and fired the cement &c is burned and at the
same time the heat that would otherwise be wasted converts converts the water
surrounding the inner chamber into steam which can be used for any desired
purpose A constant or other supply of water can be arranged―The improvements
form a combined kiln and boiler.

I, EDWIN WEST KILLICK of Lilly Villa, North Fleet, in the County of Kent,
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 :-
The improvements relate more particularly to kilns for burning cement and such
like though they may be used for drying and other purposes; they consist in
making the kiln of an inner and outer chamber of metal, one within the other
connected at top and bottom and suitably stayed to form a space intended to hold
water; the chambers are perforated for doors and for inlet and outlet pipes and
manholes, they have by preference, a cylindrical shape or plan, with a domed top
having an aperture therein for feeding and passage of the products of combustion ;-
also blow off cocks are supplied;- the bottom of the kiln is made of brick, fire
clay, or of metal conical or rising to the centre, so that the material falls towards
the doors, which are at low level ready for delivery; the outer chamber or shell
may be covered with brick or jacketted with any suitable material.-On the kiln
being charged and lighted, the cement is burned and at the same time the heat,
that would otherwise be wasted, converts the water surrounding the inner chamber
into steam which can be used for any desired purpose; a constant supply of water
can be arranged, or the water otherwise supplied;-my improvements thus form
a combined kiln and boiler.
The accompanying drawing shows this invention.
Fig. 1 is a plan view of a pair of the improved kilns.
Fig. 2 an elevation of the same one being shown in section.
Fig. 3 a plan view of the base of the kiln from below showing the arrangement
of four draught holes H.
Like letters show like parts throughout the figures.
A is the bottom of the kiln, formed of brick fire clay or metal, and made
preferably with four draught holes H and having an arched cover, the upper side
of which is conical.
B B are double walls forming the water jacket or boiler.
C is the steam chest.
Dare tubes passing across the upper part of the kiln and communicating with
the jacket B.
E is the steam pipe conveying the steam from the steam chests to the machinery
or other destination.
F the conical dome of the lower part of the kiln, which may be of metal, brick
or fire clay.
G are drawing eyes for extracting the material from the kiln, so placed at the
base of the cone F, as to enable the material to be easily removed.
Hare draught holes, preferably four in number.
K pipes connecting the jacket to the steam chest and serving also as brackets
for supporting the latter.

page_text: The cover of the kiln may be of any shape, but for burning pug I prefer a dome
shaped cover.
The advantages of this kiln are the economy in manufacture, durability, and
saving of fuel with least loss of heat,
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that, what
I claim, is:
1.) The combination of iron kilns with steam jackets B, cross tubes D and steam
chest C placed in any position on segments A with perforated conical hearth F and
drawing eyes G for discharging the material.
2.) The arrangement of this improved kiln as a continuous loading, burning
and drawing kiln for keeping up steam without the aid of extra firing, for all
machinery purposes.
