COMPLETE SPECIFICATION.
An Improved Construction of Kiln for Burning Limestone.
I, JOHN WINSKILL, Junior, of Settle, in the County of York, Builder and
Contractor, 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 :-
My invention has reference to an improved form or construction of kiln or furnace
for burning limestone. In constructing kilns according to my invention, I form a
vertical receiver or chamber for the reception of stone to be burnt, and communicating
with this vertical receiver by an elbow is another vertical chamber in which the
stone is fed. Fuel to burn the stone is introduced through a door about midway of
the two chambers, whilst another door at the bottom of the lower chamber is employed
from which to remove the burnt stone, and by employing two vertical chambers
communicating with each other the stone in the feeding chamber will settle or follow-
on every time any of the burnt stone is removed from the bottom door. I also
form two or more vertical holes through which to introduce a bar for the purpose of
breaking clinkers, but if necessary fuel may be fed through these vertical holes, if
required.
Such being the nature and object of my invention, I will now proceed to describe
the same more fully, and for that purpose make reference to the accompanying sheet
of drawings illustrative thereof, wherein Fig. 1 is section of my improved form of
kiln and Fig. 2 is plan view of same taken through the line A B. (represents the
upright receiver or chamber into which the limestone is burnt, and fuel for burning
the said limestone is introduced at the door D whilst the stone is fed to the chamber C
through the top or mouth of the chamber E, the two chambers C and D being con-
nected or put in communication by the bend or elbow H. In feeding this kiln I
propose to feed the materials after each other, so that there is a layer of stone and
then a layer of fuel. At the bottom of chamber C is a door J, from which the burnt
stone is removed, and each time the burnt stone is removed, the unburnt stone will
settle to the bottom so that the kiln becomes self feeding. The heated gases and
smoke from the kiln will pass up through the chamber E into the atmosphere, or a

page_text: chimney may be employed in connection with the said chamber E. Vertical
openings and G are formed through which to introduce an iron rod for the purpose
of breaking clinkers formed by the fuel, and if necessary some of the fuel may be
fed direct down the said vertical openings.
By forming and constructing a kiln in the manner herein shewn and described,
the limestone can be burnt with great rapidity, and with a comparatively small
consumption of fuel.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is --
In a kiln for burning limestone, the combination of the two vertical chambers C
and E communicating with each other by the elbow H, such kiln being provided with
one or more doors for the introduction of fuel, and with an outlet at the bottom of
the chambers for the removal of limestone in manner substantially as described.
Dated this 11th day of March 1889.
