Accrington, in the County of Lancaster, Bleacher, Dyer, and,
Finisher, for the Invention of "AN IMPROVED MODE OF UTILIZING
PROVISIONAL SPECIFICATION left by the said Squire Brierley
at the Office of the Commissioners of Patents, with his Petition,
on the 9th August 1875.
I, SQUIRE BRIERLEY, of Whitecroft Baxenden, near Accrington, in'
the County of Lancaster, Bleacher, Dyer, and Finisher, do hereby
declare the nature of the said Invention for "AN IMPROVED MODE OF
UTILIZING THE HEAT FROM LIME AND OTHER KILNS AND OVENS," to be as
follows:-
My Invention consists in surrounding the kiln or oven with a water
casing, at the lower end of which is the fire-grate. The lime or other
:

page_text: material to be burnt or fired is supplied near the top of the kiln or
The
oven, and the water chamber is connected by pipes to a boiler.
combustion of the fuel in the fire-grate and through the lime or other
substance is promoted by means of a jet of steam passing through a
pipe surrounded by a water casing. The products of combustion pass
through a second fire placed under or near the boiler, from which the
steam is taken to the steam engine or for other purpose to which it may
be applied.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Squire Brierley in the Great Seal Patent Office
on the 9th February 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SQUIRE
BRIERLEY, of Whitecroft Baxenden, near Accrington, in the County
of Lancaster, Bleacher, Dyer, and Finisher, send greeting..
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of August, in the year
of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Squire Brierley, Her
special licence that I, the said Squire Brierley, my executors,
administrators, and assigns, or such others as I, the said Squire
Brierley, 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, usc, exercise, and vend, within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "AN IMPROVED MODE OF UTILISING THE HEAT FROM LIME AND
OTHER KILNS AND OVENS," upon the condition (amongst others) that I, the
said Squire Brierley, my executors or administrators, by an instru-
ment 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 after the date of the said Letters
Patent. -

page_text: NOW KNOW YE, that I, the said Squire Brierley, 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 by the following statement (that is to say):
My Invention consists in surrounding the kiln or oven with a water
casing, at the lower end of which is the fire-grate. The lime or other
material to be burnt or fired is supplicd near the top of the kiln.or
oven, and the water chamber is connected by pipes to a boiler. The
combustion of the fuel in the fire-grate and through the lime or other
substance is promoted by means of a jet of steam passing through a pipe
surrounded by a water casing. The products of combustion pass
through a second fire placed under or near the boiler, from which the
steam is taken to the steam engine or for other purpose to which it
may be applied.
And in order that my Invention may be fully understood and readily
carried into. operation I will proceed to describe the accompanying
Sheet of Drawings, in which Fig. 1 represents an apparatus suitable for
generating steam, constructed according to my improved mode of
utilising the heat from kilns and ovens; Fig. 2 is a modification of the
same.
In Fig. 1a represents a kiln or oven suitable for burning lime or
other material to which my improvements are applied; this kiln or
oven is surrounded by the water casing b, at the lower end of which is
the fire-grate c; the lime or other material to be burnt or fired is
supplied through the firing door d placed near the top of the kiln or
oven. An ordinary two flued or other boiler for generating steam is
placed at e, or in any other convenient position near the kiln or oven a,
and the water space 6 is connected to the lower part of the boiler e by
the diagonal pipe f, the object of which is to ensure the circulation of
the water. The steam dome above the water space is also in com-
munication with the steam space of the boiler e by the pipe m. The
products of combustion from the fuel employed to burn or fire the lime
or other substance are conveyed from the upper end
oven a through the pipe g to. the flues of the steam boiler e, and in
order to increase the combustion of the fuel in the kiln or oven I
introduce the steam jet h into the pipe g, which is surrounded by the
water casing i; the water for this purpose is supplied from the cistern j
of the kiln or

page_text: or other convenient source. By means of this Invention all the heated
products of combustion from the kiln or oven a are conveyed above the
fires in the flues of the steam boiler e, where they are ignited or con-
sumed and are made available for generating steam, or they may be
conveyed into the furnace of a water heating apparatus, or to any other
furnace.
The sight holes, k, are for the purpose of inspecting the interior of
the oven or kiln, and the feed water is supplied at the pipe . The
water space and the boiler and provided with water gauges, safety valves,
man-holes, and other suitable apparatus, as in boilers of the usual
construction..
Fig. 2 represents a modification of my Invention. In this arrange-
ment the water space b is connected to or made with the boiler e, and
the products of combustion from the oven or kiln a pass direct into the
flue g which traverses through the length of the boiler. A steam jet
similar to in Fig. 1 may be introduced into the flue g to increase the
combustion in the oven or kiln.
Having thus stated the nature and particulars of my Invention I
wish it to be understood that I do not intend to limit myself to the
details given, as they must be varied according to the particular purpose to
which they are applied; and I claim, the improved mode of utilising
the heat from lime and other kilns and ovens, as shewn and described.
In witness whereof, I, the said Squire Brierley, have hereto
set my hand and seal, this Seventh day of February, One
thousand eight hundred and seventy-six.
SQUIRE BRIERLEY. (L.S.)
