I, JOHN EDWARD BEANLAND of Harris Street Bradford, Builder and Contractor
do hereby declare the nature of my invention for IMPROVED BRICK, QUARRY, OR
SLAB, FOR THE PURPOSE OF
STACKS," to be as follows:-
FORMING THE SMOKE AND AIR FLUE IN CHIMNEY
My invention has refernce to certain means to be employed for forming the
smoke and air flues in chimney stacks.
Such flues as at present formed are made by the workman breaking off the
corners of the bricks so as to make them to the shape required to form the flues,
but this method is not only expensive and slow, but the flues when so formed are
jaggy, leaving hollow places in some parts and projections in others, all of which
are so many places for the accumulation of soot and dust.
My invention consists in making bricks, quarries, or slabs of such a size and
shape that when they are put together in building the stacks they leave the
necessary openings for the flues.
The bricks are also so shaped that alternately, each layer is different so that the
joinings of the bricks do not come opposite each other. By this means the flues
are not only more easily and quickly made, but they are perfectly round and
parallel without the jaggy places for the reception of soot and dust, complained
of, stacks so formed also prevents the smoke passing from one flue to the other the
chimney breast or stack is also stronger. The air tubes which are made to com-
municate with the rooms of the buildings must necessarly turn in various directions
towards the rooms intended to be ventilated, the bricks for forming such twists,
bends, and turns are technically called "bends," elbows, gatherings, headers, and
stretchers.
There are also inlets, outlets, syphon, trap and other box bricks, and these are
nade to the required shape and more perfectly formed than is possible on the
present system.
The bricks, quarries, and slabs herein mentioned will be found of great advantage
to builders.

I, JOHN EDWARD BEANLAND of Harris Street, Bradford, Yorkshire Builder and
Contractor, do hereby declare the nature of my invention for "IMPROVED BRICK,
QUARRY, OR SLAB FOR THE PURPOSE OF FORMING THE SMOKE AND AIR FLUE IN
CHIMNEY STACKS," 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 certain means to be employed for forming the
smoke and air flues in chimney stacks.
Such flues as at present formed are made by the workman breaking off the
corners of the bricks so as to make them to the shape required to form the flues,
but this method is not only expensive and slow, but the flues when so formed are
jaggy, leaving hollow places in some parts, and projections in others all of which
are so many places for the accumulation of soot and dust.
My invention consists in making bricks, quarries, or slabs of such a size and
shape that when they are put together in building the stacks, they leave the
necessary openings for the flues.
The bricks are also so shaped that alternately, each layer is different, so that the
joinings of the bricks do not come opposite each other.
In order that my improvements may be better understood, I herein give
reference to the accompanying sheets of drawings, which illustrate several different
methods of putting my invention into practice.
In Fig. 1A is the smoke or chimney flue and B the air flue, both of which are
perfectly round in shape in consequence of the special formation of the bricks or
slabs C. Fig 2 and 3 shew slabs of other shapes all of which may be used in
building a chimney stack, the different shaped slabs being used for each alternate
layer so that the joinings of one set of slabs do not come opposite another set.
By this means the Blues are not only more easily and quickly made, but they are
perfectly round and parallel without the jaggy places for the reception of soot
and dust as is the case at present.
Stacks so formed also prevent the smoke passing from one flue to the other, the
chimney breast or stack is also stronger. On sheet 2 I have shewn the shape of
the slabs when the flues are square.
The air tubes which are made to communicate with the rooms of buildings must
necessarily turn in various directions towards the rooms intended to be ventilated,
and the bricks for forming such twists, bends, and turns are technically called
"bends" "elbows" " gatherings" "headers" and "stretchers."
There are also inlets, outlets, syphon, trap and other box bricks, and these are
made to the required shape and more perfectly formed than is possible under the
present system as will be observed in Fig. 4 which is section of a bend in an air
ie, the slabs being suitably shaped for the purpose.
Fig. 5 shews the outlet-end of an air flue which is provided with projections a so
as to prevent the inlet of cold air, which instead of going straight down the chimney
would strike against the plates a as shewn by the arrow b and forced back thereby.

page_text: By placing these air flues adjacent to the chimneys they get warm and an up
current is produced which aids the circulation of the air therein.
The bricks, quarries, and slabs herein mentioned will be found of great advantage
to builders.
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
The peculiar formation of bricks, quarries, and slabs substantially as are herein
shewn and described when employed for the purpose of forming smoke and air
flues in chimney stacks.
