Chimney and Ventilating Shafts.
RICHARD LEOPOLD KIRLEW % Messrs. Smith & Sons Limited 21 Whittal
Street Birmingham, Commercial Traveller, do hereby declare the nature of this
invention to be as follows:-
I propose constructing such of metal on a suitable foundation. Lattice or other
girders of sufficient strength being on the outside; cylinders or plates being on the
inside and rivetted or otherwise suitably fastened on to the girders; two or more
girders being used in the construction of each shaft. The girders to be bolted or
otherwise suitably fastened together across the shaft at such distances as may be
found to suit the shaft being at the time erected, taking into due consideration the
height, diameter and general position of shaft. On the inside are to be rings of
stamped wrought iron or steel, bolted on to the plates, cylinders or girders at suitable
distances apart to enable workmen to ascend for cleaning, repairs or examination.
This to be applicable to dwellings, and other erections either lining the brick,
cement, or stone flues with metal or constructing such entirely of metal.

COMPLETE SPECIFICATION.
Chimney and Ventilating Shafts.
I, RICHARD LEOPOLD KIRLEW of 21 Whittal Street Birmingham in the
County of Warwickshire Commercial Traveller 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 and as illustrated in
the accompanying two sheets of drawings in which :-
Fig. 1 is sectional elevation of part of a chimney or shaft, and Fig. 2 is sectional
plan of the same.
In this invention I construct chimneys and ventilating shafts by means of lattice
girders such as b, or girders of other like structure placed on the outside of cylinders
such as e, so as to support said cylinders, which are placed in the centre to form
the chimney or shaft. Two or more girders 6 may be employed in the construction
of each shaft or chimney, said girders being placed vertically and bolted together
or otherwise suitably connected and stayed by ties such as g.
The lower ends of these supporting girders are bolted to bed plates which are
laid in a concrete bed y' space being left between said beds for the construction of
the flue h.
The upper portion of girders and cylinders is surmounted by a cap or
cornice.
The aforesaid cylinders c may be built up and bolted together by means of
flanges & formed thereon or by metal rings bolted to the plates forming chimney.
The inside of cylinder may be lined with firebrick e to any required height.
For smaller chimneys such as are employed in workshops dwelling houses and the
like I construct metal flues to the shape required which I employ in lieu of brick
or stone work, as shown in Fig. 3, or line the inside of brick or stone flues with
metallic plates bolted together.

page_text: Having now particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1st. The construction of chimneys and ventilating shafts by the employment of
metallic cylinders placed vertically and supported by lattice girders, or girders of
like structure placed on the outside of said cylinders with their lower ends resting
on bed plates and secured to a concrete foundation in the manner substantially as
herein before described.
2nd. The construction of chimneys in dwelling houses, and for like purposes by
the employment of metallic flues of any required shape, or flues that are lined with
metallic plates bolted together in the manner substantially as herein before
described.
