page_text: Improvements in and connected with Brick Kilns.
I, OTTO GUSTAV HERRMANN STIFFT, of Mittenwalde /, Germany, Brick
Manufacturer, 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 :-
This invention has for its object to enable ring and oblong kilns to be worked
independently of the seasons i.e. to enable them to be worked in winter equally as
well as in summer.
To effect this the kiln is so connected with a drying house, of suitable size, that
the hot air and gases from the kiln are sucked or driven into the drying house,
where they are utilized for drying the bricks which are brought in, from the press
or stamps, on small lorries or trucks which are made to continuously expose the
bricks to the action of the heat. If the gases are not sufficiently hot thep the
temperature in the drying house can be raised by inserting one or more tubes in
the kiln through which air is sucked into the kiln. The air, which is heated by
coming in contact with the red-hot walls of the tubes, passes into the drying house
so as to raise the temperature sufficiently to dry the bricks.
And in order that my said invention may be properly understood, I have hereunto.
appended an explanatory sheet of drawings, whereon
Fig. 1 is a part side elevation and Fig. 2 a sectional plan of a kiln provided with.
a drying house.
Referring to the drawings :-
A is the engine or stamping house, B the drying house, and C the kiln. The
drying house, B, which is beside the engine house A, is made like a long shed and
is provided with four sets of rails a which lead to the engine house and to the kiln..
The rails have turn tables b at the crossings. Below the rails a are channels or
passages c (shown in dotted lines) through which, by the action of one or more
exhaust fans or the like, the damp and cold air, is withdrawn. The passage e leads.
from the flue to the ventilating fan or blowerf which also serves for sucking up the
hot air emanating from the kiln C. The fan or blower of may, with advantage, be
fitted in connection with a pipe g arranged across the drying house. The pipe g
has several outlets so that the hot gases passing from the ventilator may be spread
equally throughout the house B. The passages c, e and
with dampers or regulators to regulate the ad and are preferably provided
cold-damp-air and the
introduction of hot air or gases.
The drying house B is made of such length that during the passage of the loaded
trolleys or trucks through the house the bricks will be sufficiently dried to be
in a condition for passing on to the kiln C to be burned.
As already mentioned the temperature of the drying house may be increased by
inserting tubes into the kiln and drawing air, by means of the ventilating fan or
blower, through the red hot tubes and discharging the hot air into the drying
house.
By evaporating the moisture from the soft bricks in the drying house, as herein-
before described, the manufacture is considerably accelerated. It is also possible
by the process to manufacture bricks equally as well in winter and cold or wet
weather as in summer.
By the improved arrangements the process is not only accelerated in comparison
with the old system, where drying houses were used in which merely open-air-
drying was carried on, but of the space occupied by the buildings or brick stacks
is saved. Further there is a considerable saving in first cost as no drying-scaffolding
is required. Also there is no necessity for loading, unloading and reloading the
Paine B27

can also be continued during rain and frost.
On account of the accelerated working it is possible to undertake the work with
a much smaller capital expenditure.
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. The combination of the engine or stamp house A, with a drying house B, and
a continuous kiln C, all arranged and operating, substantially as hereinbefore
described and for the purpose of enabling a continuous and accelerated manufacture
of bricks to be carried on.
2. The general construction and arrangement of the houses A and B and kiln C
with the rails a, trucks h, hot air or gas passage e, fans or equivalent f, and cold and
damp air exhausting passages c, substantially as herein before described with
reference to the drawings annexed.

No. 3. Collar inclined downwards and fixed on No. 2.
No. 4. Four brackets upon which to rest the deflecting pot or No. 6.
No. 5. Collar inclined upwards and fixed at the bottom of No. 6 forming an
entrance and exit for air in case of down draft.
No. 6. Deflecting pot.
No. 7. Three rods on which No. 8 moves up and down.

COMPLETE SPECIFICATION.
Improvements in Chimney and Ventilating Shaft Tops.
I, JOHN GILBERT HARTELL 29 Horsefair St. James Bristol Master Boot
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 :-
The object of this invention is to prevent any down draught in chimneys and my
invention accomplishes this by a simple arrangement of a deflector of conical shape
supported within the cowl near the top.
Referring to the drawings left with my Provisional Specification, it will be seen
that any wind entering the cowl, would impinge on deflector 8 and be deflected and
escape to the open air through circumferential port 9 provided in collar 5. This
deflector 8 slides up and down upon rods 7 fixed upon 2.
Having now particularly described & 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. The combined arrangement & construction of the chimney cowl, substantially
as herein described and illustrated in the accompanying drawings.
2. In chimney cowls as described, the use of a deflector 8, constructed and
arranged, substantially as herein described & illustrated in the annexed drawings
for preventing down drafts.
