page_text: builder do hereby declare the nature
There are 3 different flue arrangements:
1stly. The heat creating flues a, b, c, d.
2ndly. The main heat flue e.
3dly. The heat outgoing flues f, 1. and h.
Each of the 16 chambers of the kiln have a separate flue system f, f 1. and h with
heat flue damper i cach chamber has also one removable shutter K, on purpose to
concentrate the heat in the main heat flue e, to that chauber, where drying of green
bricks or Terra Cotta Stuff is wanted.
Every chamber has one smoke flue damper l, bringing, when drawn, the chambers in
connection with the chimney g.
The heat creating flues a, b, c, d, are all going rund on the top of the arches of
the kiln, having one outer air ventile, running from flue a, into b, from b, into c,
from C₁ into d, and from d across the chamber arches through inlets or n into the
main heat flue from where the heat can be drawn into any chamber required, with
opening the corresponding heat flue damper i.
When a kiln is at work, the brickwork and particularly the arches become red hot,
the outer air, entering the flues a, b, c, d, by ventil passing close by the red hot
brickwork, gets heated to a very high degree.
The currence of the outer air, through the different flues is caused, with bringing
one chamber for drying green material in connection with the chimney, through
opening smoke flue damper l, and heat flue damper i; the draft of the chimney
causing the air, to pass the beat creating flues a, b, c, d, to runn by the inlets m, or n,
into the main heat flue e, entering the chamber through fire feeding holes
which
are connected with the outgoing flues fand f1. and flue . on the bottom of the kiln
(chamber) dryes the material and escapes with the water vapours through the
shimpar a

page_text: It has to be performed as follows:
Supposing chamber No. 7 would be the drying chamber, chambers No. 1 to 6 would
than be the burning chambers, chamber No. 7 would have to be airtied towards
chamber No. 6 and 8 by means of large iron shutters; the smoke flue damper, the
heat flue damper of chamber No. 7 have to be opened, the shutter closes by 7. the
main heat flue, ventil a is opened, the heated air out of the fines a, b, c, d, enters
the main heat flue e, by inlet m, goes by the outgoing flues, 1. and h into chamber
No. 7. to dry the green material therein.
After 24 hours drying, the material is perfectly dry, chamber No. 7 would than
be connected with the burning chambers, and chamber No. 8 would be on next
for drying.
Dated this 31st day of October 1887.

page_text: 3dly. The heat outgoing flues f,fl. and h.
Each of the 16 chambers of a chamber kiln have a separate flue system f. 1. and h,
with heat flue damper i, each chamber has also one removable shutter k, on purpose to
concentrate the heat in the main heat flue e, where drying of green bricks or
terra-cotta ware is wanted.
Every chamber has one smoke flue damper l, bringing when drawn, the chambers
in connection with the chimney.
The heat flues a, b, c, d, are all going round on the top of the arches of the kiln,
having one outer air opening a, running from fluo a, into fine b, from flue b, into
flue c, from flue c into flue d, these heat flues a, b, c, d, are connected with the main
heat flue e, by inlet m, on one length side of the kiln, and by inlet n, on the other
the heat can be drawn into any
length side of the kiln; from the main heat flue e,
chamber required, with opening the heat flue damper i, and the smoke flue damper 1,
reference being had to the accompanying drawings.
The drawings contain 5 figures:
In figure 1 part A, is showing an horizontal section of a kiln, taken on the floor of
the chambers, part B. is showing an horizontal section of a kiln, taken 1 foot above
the chamber floor.
In figure 2 part C, is showing an horizontal section of a kiln with the heat flue d
and inlets m, and n, and the outgoing flues f, f1. and ; part D. is showing an
horizontal view on the top of a kiln, when finished.
Figure 3 is showing a vertical section of a kiln (length way) with the heat
flues a, b, c, d, main heat flue e, and the outgoing flues f1.
Figure 4. is showing a vertical section of a kiln with the heat flues a, b, c, d, and
inlet m running into the main heat flue e.
Figure 5 is showing a vertical section of a kiln with the outgoing flues f, f1 and h,
and also the main heat flue e, with the heat flues a, b, c, d, also showing the heat
flue lamper i, and smoke flue damper l.
In order to thoroughly dry green bricks, tiles or Terra-Cotta ware, before the
burning of the goods takes place, and without any expense for fuel and labour,
this hot-air drying system produces a great heat, that green material is freed of
all moisture, thus preventing staining of the goods, not allowing the smoke and
rofuse from the combustion of fuel, to stick to the surface of the green but

page_text: dry during 24 hours drying, the drying chambers, whether 1 or 2 or 3 are on for
drying are always next to the burning chamber; say, chambers No. 10 & 11 are on
for hot-air-drying; and to bring these 2 chambers in operation with the heat flue
system, the smoke flue damper 7, and the heat flue damper of chambers 10 & 11 are
drawn, the opening is opened, the shutter k, closes the main heat flue e by
chamber No. 11, shutter o, closes the heat-flues a, b, c, d, to inlet m, the outer air
entering the heat flues a, b, c, d, by opening, runns into the main heat fluo e, by
inlet π, from the main heat flue e, the heated air is led into the chambers No. 10 & 11
by the corresponding outgoing flue system f, f 1. and h.
When the fire has progressed so far, that the chamber shutter between the chambers
No. 9 & 10 requires drawing, the heat flue damper of chamber No. 10 the smoke
flue damper 7, of chamber No. 9 must be shut the drying of chamber No. 10 being
finished, and is thus connected with the burning chambers. Chamber No. 12 would
have next to be brought in operation with the heat-flue-system, with removing
shutter from chamber No. 11 into chamber No. 12, and opening the heat fluo
damper i and smoke flue damper t, of chamber No. 12; after the fire is progressing
another chamber, chamber No. 11 must be connected with the burning chambers, and
chamber No. 13 has to be brought in operation with the hot-air-flue-system; and so
continuing round.
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 :
1. In the construction of chamber kilns the arrangement of the heat flues a, b, c, d,
with opening on the top of the chamber arches; the main heat flue e, with
inlets mt, & in connection with the heat flues a, b, c, d ; the outgoing flues f,f1. & h,
substantially as described and shewn in the drawings.
2. The general arrangement and construction of parts together forming my
invention of "Improvements in clamber-kilns" as herein before described and shown
in the drawings.
