Improvements in Continuous Kilns.
I, EDWIN THOMAS, of 49, Orsett Road, Grays, in the County of Essex, Brick
Maker, do hereby declare the nature of this invention to be as follows
--
My invention relates to continuous kilns and has for its object to provide means
whereby any single chamber or oven may be worked separately.
According to my invention the several chambers have permanent walls built
between them and each chamber is fired from a furnace formed by building up a
supplemental wall or partition within the chamber against the main dividing wall,
the said supplemental furnace being fired from above in the usual manner of firing
kilns.
Each of the main partition walls is provided with flues or passages which have
caps or dampers so that they can be used either to connect adjacent chambers when
firing continuously or to conduct the smoke or steam to main smoke and steam flues
when firing independently or drying. Instead of forming a series of chambers
separated by partition walls as described I may place the several chambers at
sufficient distances apart to permit of firing each chamber from the side; in this
case the flues or passages which connect adjacent chambers are extended cross the
spaces between such chambers.

1, EDWIN THOMAS, of 49 Orsett Road, Grays, in the County of Essex, Brick
Maker, 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 relates to continuous kilns and has for its object to provide means
whereby any single chamber or oven may be worked separately.
According to my invention the several chambers have permanent walls built
between them and each chamber is fired from a furnace formed by building up a
supplemental wall or partition within the chamber against the main dividing wall,
the said furnace being fired from above in the usual manner of firing kilns.
Each of the main partition walls is provided with flues or passages which have
caps or dampers so that they can be used either to connect adjacent chambers when
firing continuously or to conduct the smoke or steam to main smoke and steam Hues
when firing independently or drying.
Instead of forming a series of chambers separated by partition walls as described
I may place the several chambers at sufficient distances apart to permit of firing
each chamber from the side; in this case the flues or passages which connect
adjacent chambers are extended across the spaces between such chambers.

page_text: To enable my invention to be fully understood I will describe it by reference to
the accompanying drawings; in which :-
Figure 1 is a horizontal section of a continuous kiln constructed according to my
invention.
Figure 2 is a vertical section on the line 2-2 of Figure 1.
Figure 3 is a transverse section on the line 3-3 of Figure 1, and
Figure 4 is an end view of the kiln.
a a are the chambers and bb the permanent walls built between them. CC arc
the supplementary walls or partitions within the chambers a a against the main
dividing walls bb. These walls or partitions ce form the furnaces for firing the
chambers aa the said furnaces being fired from above in the usual manner of liring
kilns. d d are the flues or passages formed in the partitions or walls bb, which
passages d d communicate with the furnace of one of the adjacent chambers through
the opening e and with a passage of the other adjacent chamber as seen clearly in
Figure 2. are the caps or dampers by means of which communication between
two chambers through the passages or flues d d is cut off. the said caps g g being
operated from the top of the kiln in the usual manner.
is the main smoke flue and the main steam flue the said flues passing to the
chimney. The passages ff communicate with the main smoke and steam flues by
means of flues and respectively, which flues and are provided with caps or
dampers as shown in Figure 3.
The operation of my improved continuous kiln is as follows:-
:-
One of the chambers is fired, the caps y lealing to the next chamber and the
damper being closed, and the steam flue damper being left open so that the
steam just given oft by the contents of the chamber passes to the main steam flue i
through the passage and so reaches the chimney. When all the moisture has
been driven off the cap or damper of the steam flue is closed and the smoke flue
damper is opened to allow the smoke evolved to pass to the chimney through the
flues and h.
It will be obvious that all the chambers can, if desired, be fired separately in this
manner. When it is desired, however, that the kiln shall work continuously the
damper g leading from the first above named chamber to the next or second chamber
is opened, after the contents of the first chamber are sufficiently dried, so that hot
gases or nir pass to the second chamber which has its steam flue damper opened
and its smoke flue damper 2 closed. When all moisture has been expelled from
the contents of the second chamber the damper is closed and the damper '
opened as above described with reference to the first chamber. By thus manipu
lating the various dampers the operation can be rendered continuous through all the
chambers.
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 1
claim is :-
1. A continuous kiln wherein the chambers are divided by permanent partitions
containing Blues provided with caps or dampers and wherein the furnace of each
chamber is formed by a supplementary wall or partition against the main partition,
substantially as and for the purpose hereinbefore described.
2. In a continuous kiln providing each chamber with separate steam and smoke
Alues leading to separate main steain and smoke flues, substantially as and for the
purpose hereinbefore described.
3. The improved continuous kiln hereinbefore described and illustrated in the
accompanying drawings.
