A NEW OR IMPROVED CONSTRUCTION OF LIME KILN
Year: 1872

page_text: LETTERS PATENT to John Winskill, of the Firm of John Winskill
and Sons, of Settle, in the County of York, Builder, for the Inven-
tion of "A NEW OR IMPROVED CONSTRUCTION OF LIME KILN.”
Scaled the 21st February 1873, and dated the 22nd August 1872.
PROVISIONAL SPECIFICATION left by the said John Winskill at the
Office of the Commissioners of Patents, with bis Petition, on the
22nd August 1872.
I, JOHN WINSKILL, of the Firm of John Winskill and Sons, of Settle,
in the County of York, Builder, do hereby declare the nature of the said
Invention for "A NEW OR IMPROVED CONSTRUCTION OF LINE KILE," to bo as
follows: --
This Invention relates to an improved construction of kiln, whereby
the feeding and supplying of limestone and fuel is greatly facilitated
and the fuel employed is economized.
In constructing kilns according to this my Invention I employ an
upright receiver or receptacle for the "stone" to be burnt, and in the
lower portion of which the burnt stone or lime cools, and at the bottom

page_text: 66
thereof is an aperture for the discharge or removal thereof. Connected
with the upper part of the receiver or kiln is an inclined flue which
serves as a feeder," by means of which the kiln is furnished with a
supply of limestone to be burnt. The said inclined flue also serves as
a flue for the passage of heated gases and smoke to an ordinary chimney,
and under the inclined flue are one or more smaller flues for the passage
and further description of heated gases among the unburnt stone.
Dampers are employed in connection with the inclined feeder so as
to regulate the supply of stone to the kiln to be burnt, and a door or
doors is provided over the kiln through which the same is supplied with
coal or fucl.
This construction of kiln gives great facilities for supplying the stone
and fuel thereto, and it will be seen that the kiln is self-feeding, because
as the burnt stone or lime is removed through the mouth or aperture at
the foot of the kiln the stone in the incline will slide down or descend
to the kiln, and also that the fuel is greatly economized, because the
stone contained in the inclined feeder is exposed to the action of all the
superfluous heat arising from the kiln during its passage therefrom to
the fluc.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said John Winskill in the Great Seal Patent Office on
the 22nd February 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
WINSKILL, of the Firm of John Winskill and Sons, of Settle, in the
County of York, Builder, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of August, in the year
of our Lord One thousand eight hundred and seventy-two, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said John Winskill, Her special licence that I, the
said John Winskill, my executors, administrators, and assigns, or such
others as I, the said John Winskill, my executors, administrators, and
assigns, should at any time agree with, and no others, from time to

page_text: 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 "A NEW OR IMPROVED CONSTRUCTION OF LIME
KILN," upon the condition (amongst others) that I, the said John
Winskill, 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 after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Winskill, 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 and accompanying Sheet of Drawings, that is to
say:-
This Invention relates to an improved construction of kiln, whereby
the feeding, and supplying of limestone and fuel is greatly facilitated
and the fuel employed is economized.
In constructing kilns according to this my Invention, I employ an
upright receiver or receptacle for the "stone" to be burnt, and in the
lower portion of which the burnt stone or lime cools, and at the bottom
thereof is an aperture for the discharge or removal thereof. Connected
with the upper part of the receiver or kiln is an inclined flue, which
serves as a "feeder," by means of which the kiln is furnished with a
supply of limestone to be burnt. The said inclined flue also serves as a
flue for the passage of heated gases or smoke to an ordinary chimney,
and under the inclined fluc are one or more smaller flues for the passage
and further distribution of heated gases among the unburnt stone.
Dampers are employed in connection with the inclined feeder so as to
regulate the supply of stone to the kiln to be burnt, and a door or doors
are provided over the kiln through which the same is supplied with coal
or fuel.
This construction of kiln gives great facilities for supplying the stone
and fuel thereto, and it will be seen that the kiln is self-feeding, because
as the burnt stone or lime is removed through the mouth or aperture at

page_text: the foot of the kiln, the stone in the incline will slide down or descend
to the kiln, and also that the fuel is greatly economized, because the
stone contained in the inclined feeder is exposed to the action of all the
superfluous heat arising from the kiln during its passage therefrom to
the fluc.
•
In order that this Invention may be more clearly understood, I hercin
give reference to an accompanying Sheet of Drawings of a kiln con-
structed according to this Invention.
Fig. 1 represents a vertical section taken through the line A, B, in
Fig. 2, which is a sectional plan taken through the line C, D, in Fig. 1.
A is an ordinary upright kiln receiver or receptacle in which the lime-
stone is to be burnt, provided at its lower part with an aperture or
opening A' through which the contents are to be removed after being
burnt. The limestone is to be introduced to this receptacle through or
by means of an inclined feeder B provided at the top with an opening
and door or doors C, and the fuel is introduced to the receiver through
a door or doors D. The heated gases and smoke from the kiln pass up
the inclined feeder B and thence to an ordinary chimney F. At the
back of this inclined feeder are one or more smaller flues G for the
purpose of drawing the heated gases in that direction in order to obtain
better distribution thereof amongst the limestone.
The heated gases
passing through the flue or flues G also create a draught or current in
the chimney shaft, which assists the passage of the heated gases or
smoke through the limestone in the feeder B. It will now be seen that
by supplying the fuel through the doors D it can be spread over that
portion of the surface of the limestone represented by the dotted line H,
and when lime or burnt limestone is withdrawn through the aperture A¹,
a settlement takes place, and more limestone is supplied through the
feeder B, and another layer of fuel is supplied to the limestone through
the door D, and thus the matters or materials in the receiver or kiln
consist of alternate layers of stone and fuel. There being no outlet
for the heated gases except through the feeder B and flue or flues G
into the chimney the limestone in the feeder becomes greatly heated
before it comes in contact with the fucl.
Having thus described the nature of my said Invention and shewn by
Drawings how the same is to be carried into practical operation, I would

page_text: have it understood that I do not confine myself to the precise details of
construction and arrangement herein shown and described, but what I
claim as my Invention is, the peculiar. construction and arrangement
thereof, substantially as herein shewn and described.
In witness whereof, I, the said John Winskill, have hereunto set my
hand and seal, this Nineteenth day of February, in the year of
our Lord, One thousand eight hundred and seventy-three.
Signed, sealed, and delivered
by the within-named John
Winskill in the presence of
