Improvements] in Chimney Tops.
I, LEONARD LLOYD of 48 Park Road, Lenton in the Borough of Nottingham,
Commission Agent do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in chimney tops, and it has for its
object to provide a chimney top that will more effectually prevent down
draughts.
In carrying out this invention I make the main part of the chimney top
preferably in the form of a hollow truncated cone with a flange at or near the
lower end, the upper face of this flange is formed concave so as to form a curved
annular deflector that will deflect a downward current of air up the conical exterior
surface.
Surrounding the upper part of the conical main part but with an intervening
space is an outer conical casing, and the space between the two is divided by a
suitable number of radial partitions, these partitions are extended down to the
annular deflector, their width at the lower end being preferably increased to that
of the deflector.
The lower edge of the outer conical casing is arranged at a suitable distance
from the deflector, while its upper end is preferably carried above that of the main
part.
The chimney top may be constructed of earthenware or metal and the outer
casing may be fixed or detachable, in the latter case projections are formed on
the radial partitions to receive the lower edge of the outer casing, and the latter
may be secured in position by a key, cement, or other means.
In some cases the main part instead of being conical may be curved from the
lower to the upper part, the latter being preferably of a less diameter than the
lower part; the outer casing may be also of similar form.
Holes or channels may be formed in the annular deflector in order to drain off
any rain water which it may receive.

Improvements in Chimney Tops.
I, LEONARD LLOYD, of 48, Park Road, Lenton, in the Borough of Nottingham,
5 Commission Agent, 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 improvements in chimney tops, and it has for its

page_text: Fig. 2. a plan, and
Fig. 3. a vertical section of a chimney top constructed according to my
invention.
Fig. 4. is a vertical section, showing a duplex arrangement.
Like letters indicate like parts throughout the drawings.
In carrying out this invention the upper portion A. of the main part of the
chimney top, is preferably made in the form of a hollow truncated cone, with a
flange B, at, or near the lower end. The upper face B' of the flange B is formed
concave so as to form a curved annular deflector that will deflect a downward
current of air up the exterior of the conical portion A.
Below the flange B is a parallel part C for setting into the brickwork of the
chimney.
Surrounding the upper conical portion A is an outer conical casing D, and the
size of the latter is such as to leave an annular space E between the upper
portion A and casing D. This space is divided by a convenient number of
preferably radial partitions F, which may be secured to or formed on the
part A.
The partitions F extend down to the upper face B₁ of the flange B, their width
at that part being preferably increased to the width of the flange B.
The lower edge D' of the casing D is arranged at a suitable distance from the
upper face B' of the flange B whilst its upper end is carried above that of the
main part A as shown.
The chimney top may be constructed of metal or earthenware, and the outer
casing D may be fixed or detachable, in the latter case shoulders F¹ are formed
on the radial partitions F to receive the lower edge D¹ of the casing D, and the
latter if desirable may be secured in position by keys, cement or other convenient
means.
If preferred the part A, instead of being shaped as shown, may be curved from
the lower to the upper part, the latter being preferably of a less diameter than the
lower part; the outer casing may be also of similar formation.
Holes or channels may be formed in the flange.B in order to drain off any rain
water that may collect in the upper face B'.
In the duplex arrangement shown in Fig. 4. the casing D is formed with an
annular deflector G, which is a duplicate of that formed by the flange B B¹,
Surrounding the casing D is a second casing H and the size of this latter casing is
such as to leave a second annular space I between the casings D and H, this.
space I is divided by radial partitions J, secured to or formed on the casing D, in.
the same manner as the space E.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
(1.) In a chimney top the combination with a conical part such as A of a
casing such as D and a deflector such as B', substantially as described.
(2.) In a chimney top the combination with a conical part such as A of a
casing such as D, a deflector such as B' and partitions such as F, substantially as
described.
(3.) In a chimney top the combination with a conical part such as A of casings
such as D and H and deflectors such as B₁ and G, substantially as described.
(4.) In a chimney top the combination with a conical part such as A of casings
such as D and H, deflectors such as B and G and partitions such.ns. F and,J,
substantially as described.

page_text: (5.) The combination and arrangement of parts constituting the complete
chimney top substantially as described and illustrated in the accompanying
drawings.
