Improvements in Kilns for Heating or Burning Pottery and the
like.
"
I, THOMAS SEVERN, of Market' Street, Heanor, in the County of Derby, Fore-
man Potter, do hereby declare the nature of this invention to be as follows:--
My invention relates to the construction of kilns for heating or burning pottery
and the like and is intended to apply more particularly to kilos in which the
"mouths "
or fire holes run longitudinally being fed at each end, the object of my
said invention being to effect more perfect combustion of the fuel and consumption
of the products of such combustion. In these kilns the "mouths" or fire holes run
along the sides of the kiln and the products of combustion pass through the inside
of the kiln to a central chimney, and in carrying out my invention I build or form.
alongside the mouths or heat conducting passages and parallel with them separate:
chambers or flues communicating with and introducing atmospheric air in such
quantities as may be desired, the intake being regulated by dampers or like devices.
These air flues supply atmospheric air to the "mouths" or heat passages through
suitable apertures; feeding at intervals the said air into the tops of the said
"mouths," the apertures being preferably of larger area as they approach the
centre of the kiln.

COMPLETE SPECIFICATION.
Improvements in Kilns for Heating or Burning Pottery and the
like.
I, THOMAS SEVERN of Market Street, Heanor in the County of Derby, Fore-
man Potter, 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 :-
or firo
My invention relates to the construction of kilns for heating or burning pottery
and the like and applies more particularly to kilns in which the "mouths
holes run longitudinally of the kiln and are fed at each end thereof the object of
my invention being to economise fuel and effect more perfect combustion of such
fuel and consumption of the products of such combustion.
"
In kilns constructed in the above manner the "mouths or fire holes run along
or near the sides of the kiln or on either side of the centre thereof and com-
municate with a central chimney or shaft.
Referring to the accompanying sheet of drawings on which
Figure 1 is a plan (on line 6-6 of Fig. 2) and
Figure 2 an enlarged vertical transverse section (on line a-a of Fig. 1) of a
kiln constructed according to my invention will proceed to describe such
construction.
Running longitudinally of the kiln I form mouths or heat passages A Anta
low level and other parallel mouths or heat passages B B at a higher level com-
municating by outlets 1111 with the furnace or kiln J the fuel C being supported
on bars D over ashpits and drafts E. Alongside and parallel with the mouths or
heat passages form separate flues. or chambers F F F F for the admittance of

page_text: fresh or cold air and closed at their extremities by doors or dampers (not shown on
drawings) by which the intake may be regulated. The cold air from flues FFFF
passes by orifices H H H'H' over the mouths or heat passages A A B B in the
direction and as shown by arrows and so into the main furnace or kiln J in which
are packed the articles to be heated or burnt.
The dampers may be opened when the fires are fed and closed when requisite,
and the orifices increase in size from the outside to the centre line -x 80 as to
distribute the fresh air as evenly as possible over the full length of the mouths for
instance I may have the outer orifices 3" x 1" and the inner ones 41″ × 2″.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
In kilns for heating or burning pottery and the like having longitudinal
"mouths." or fire holes running throughout the length of same, the construction of
separate and parallel passages or chambers such as F F F F communicating with
such mouths or fire holes by means of apertures at right angles thereto such
as H H H'H' of increasing size towards the centre of the kiln and controlled by
external doors or dampers substantially as hereinbefore described and as illustrated.
by the accompanying drawings.
Dated this 29th day of March 1892.
