Improvements in the Construction of Cupolas and the like.
I, ALEXANDER EADIE, Foundryman, in the employment of James Simpson &
Company Limited, of Engine Works, Grosvenor Road, in the County of London,
do hereby declare the nature of this invention to be as follows:-
This invention relates to certain improvements in the construction of cupolas,
or the like, such as are used in foundry work.
In carrying out this invention the use of the ordinary fire bricks is discarded
wholly or mainly and in place thereof I employ bricks, or the like forms, of
cast iron and these bricks may be made and used either solid or cored out, so as
to be more or less, hollow.
In a construction which I have tested experimentally
introduce one ordinary fire brick, or block, at each course.
find it convenient to
The cupola may be constructed in parts of hollow cast iron bricks, or blocks
and in other parts of solid cast iron bricks, or blocks, as may be found
convenient.
By these means I am enabled to construct a cupola of greater lasting character
than one made of ordinary fire brick, and possessing besides other advantages.

Improvements in the Construction of Cupolas and the like.
I, ALEXANDER EADIE, Foundryman, in the employment of James Simpson &
Company Limited, of Engine Works, Grosvenor Road, in the County of London,
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 relates to certain improvements in the construction of cupolas,
or the like, such as are used in foundry work.
In carrying out this invention the use of the ordinary fire bricks is discarded
wholly or mainly and in place thereof I employ bricks, or the like forms, of
cast iron and these bricks may be made and used either solid or cored out so as
to be more or less, hollow.
In a construction which I have tested experimentally I find it convenient to
introduce one ordinary fire brick, or block at each course, but this detail is
not essential

as may be found
By these means I am enabled to construct a cupola of greater lasting character
than one made of ordinary fire brick and possessing besides other advantages.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 shows a sectional elevation of a part of a cupola constructed according
to my invention;
Fig. 2 shows a transverse sectional view thereof taken on the line A-A of
Fig. 1;
Fig. 3 shows a portion of a course of the improved hollow cast iron bricks, or
blocks drawn to a larger scale;
Fig. 4 shows one of such bricks or blocks in plan;
Fig. 5 shows a vertical section of parts of two of such bricks on the line B-B
of Fig. 3, and Fig. 5 shows a cross section of one of the same on the line C-C
thereof;
Fig. 6 shows a transverse sectional view of a cupola corresponding to Fig. 2,
but with the use of bricks or blocks in which the key pieces are dispensed with;
Fig. shows a part of a course of bricks according to the construction of
brick shown by Fig. 6 and drawn to a larger scale;
Fig. 8 shows one of the bricks according to Fig. 6 in plan view; and
Fig. 9 shows a cross section of same on line D-D of Fig. 7.
a, a, are the cast iron bricks, or blocks herein shown as formed with hollow
spaces a². In the arrangement indicated by Figs. 1 to 5 inclusive the fins or
projections on the male bricks a fit into corresponding recesses in the female
bricks a', whilst, if in the arrangement of a course of bricks two female bricks
meet, the space (1) may be left, or be filled by any suitable material.
In the arrangement shown by Figs. 6 to 9 the male and female projections
and recesses may be dispensed with, and at each course a filling piece, or ordinary
fire brick may be inserted amongst the bricks a. c, c, are air holes, or passages
formed in the outer casing, d, the ordinary firebrick construction and the outer
sides of the hollow iron bricks, or blocks.
One, or more of the courses of hollow iron bricks or blocks may be formed as
indicated at a with a recess or groove on their upper, or it may be on their upper
and under mid surfaces.
The lower and upper portions of the cupolas, above and below the hollow cast
iron brick portion, I prefer to construct of fire brick and iron casing f
substantially as usual.
d, d, indicate tuyere holes and e the charging opening.
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:-
1. The use of bricks, or like forms of cast iron, solid or cored out, to form the
lining of cupolas, or the like, employed in foundry work, or such like industries,
as set forth.
2. The use of bricks, or like forms of cast iron, either solid or cored out, in
the construction of the linings of cupolas, or the like, for foundry, or other like
uses, in combination with usual fire brick for other parts thereof, as set forth.
3. The use of cast iron hollow bricks, or forms, as linings for cupolas, or
the like, for foundry, or other uses, substantially as shown and described.
4. The construction and use of cupola lining, or lining for a similar purpose
wherein courses of hollow iron bricks or blocks are arranged in combination
with usual parts of a cupola, or the like, as described and shown by the drawings
with reference to Figs. 1 to 5.
5. The construction and use of a lining for a cupola, or the like, wherein

parts of a cupola or the like, as described and shown by the drawings with
reference to Figs. 6 to 9.
