An Improved Chimney.
I, EMILY HARRIET KNIGHT, of No. 161, Battersea Rise, in the County of London,
Confectioner, do hereby declare the nature of this invention to be as follows:-
The chimney is composed of a series of basins or cups of zinc, pottery ware,
or other suitable material. Each of these basins or cups is made without a
bottom, and every two of them are joined together, at their mouths, in any con-
venient manner, and thus form a cupola shaped section of the chimney.
In the lower part of each section, holes are pierced around its circumference,
and into these holes tubes of a convenient diameter fit. These tubes are attached
to the inner side of the schell of the section, and are about equi-distant from each
other. They are, intended to act as air shafts for creating an updraught. In the
centre of each section there must be a vacuum or flue of at least, 6" diameter.
The first section of the series is securely attached, by any suitable means to the
cap of the chimney stack, and on the top of this section another section is fixed.
In this manner the chimney may be raised to any desired height.

I, EMILY HARRIET KNIGHT, of No. 161, Battersea Rise, in the County of London,
Confectioner, 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 has for its object an improved chimney. It is fully delineated
by the accompanying drawings in which
Figure 1 is an elevation of the chimney in its simplest form, in which only
a single cupola shaped section is employed.
Figure 2 is an elevation of the chimney formed of a double cupola shaped
section.
Figure 3 is an elevation of the chimney formed of a double, and a single cupola
shaped section.
Figure 4 is an elevation showing the sections apart from each other.
Figure 5 is a section of a cupola shaped section.
Figure 6 is a plan.
Like letters of reference denote like parts throughout the several figures.

page_text: The chimney may consist of, a single section a Figure 1, attached to a base by
a collar a¹, and attached to the cap c by the collar a². The cap c has an opening c¹.
The chimney may also consist of a double section b, b, Figure 2 attached to a
base by the collar 4, and to the cap e-in which there is an opening c-by the
collar. The collar 62 joins the sections b, b and so the double section is formed.
The chimney may also consist, of a single section a Figure 3, and a double
section b, b attached to the base by the collar b¹, to the cape by the collar a², and
to each other by the collars a', 62, 63 Figure 3.
The material of the chimney may be pottery or zinc or other suitable material,
or metal,
The single section
and double section b, b are respectively composed of basins
or cups, each of which is without a bottom, joined together at their mouths by
any convenient means. Holes, d, are cut around the lower portion, or half of each
section, and into these holes tubes of a convenient diameter fit as shown by
the dotted lines in the several figures, and are attached by suitable means to the
inside of the section, as shown by Figure 5 of the drawings. These holes and tubes
are intended to create up-draughts. In the centre of each section there is a flue
or vacuum of at least 6" diameter. The sections composing the chimney are
attached to each other, and to the cap, and base of the chimney by the means
herein specified, and illustrated by the drawings, but I do not confine myself to
these means of attachment as I may use any other convenient forms.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. The chimney designed and constructed as herein specified as and for the
purpose herein mentioned.
2. The combination and arrangement of the basins or cups herein mentioned,
designed and constructed to form cupola shaped sections, substantially as and
for the purpose herein described.
Dated this 27th day of June 1898.
