Ventilator for Buildings and for Curing Smoky Chimneys.
JAMES TROOP 28 Quinn Square Waterloo Road London S.E. Engineer do hereby
declare the nature of this invention to be as follows:-
My invention consists of an appliance made of any suitable material but preferably
of cast iron which can be inserted in place of the air bricks in buildings to act as a
ventilator or fixed in the chimney breast to prevent down draught it consists of a box
having an opening or openings at the lower extremity next the room and an opening
or openings in the upper extremity in the flue with partitions the width of the box
standing up from the bottom nearly to the top and partitions the width of the box
standing down from the top nearly to the bottom these partitions come between those
that stand up from the bottom of the box.
The openings at the lower extremity of the box preferably I make smaller than those
in the upper extremity.
In some cases I arrange the partitions to stand horizontally instead of vertically or
at an angle.
The same appliance fixed so that the openings in the lower extremity come next the
outside can be used to admit fresh air into buildings and can be fitted with un
adjustable regulator to cover or partly cover openings when desired.

JAMES TROOP 28 Quinn Square Waterloo Road London S.E. Engineer 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 consists of an appliance made of any suitable material but preferably
of cast iron which can be inserted in place of the air bricks in buildings to act as a
ventilator or fixed in the chimney breast to prevent down draught it consists of a box A
(Figs. 1. 2) having an opening or openings B at the lower extremity next the room
and an opening C or openings in the upper extremity in the flue D (Fig. 3.) with
partitions E (Figs. 1. 2) the width of the box standing up from the bottom nearly to
the top and partitions F the width of the box standing down from the top nearly to
the bottom these partitions F come between those E that stand up from the bottom of
the box.
The openings B at the lower extremity of the box A preferably I make smaller than
those C in the upper extremity.
In some cases I arrange the partitions to stand horizontally instead of vertically
or at an angle or of a curved or other form instead of straight and I do not confine
myself to the exact number of partitions or openings or to the exact shape of the
openings shown.
The same appliance A fixed so that the openings B in the lower extremity come
next. the outside can be used to admit fresh air into buildings and can be fitted
with an adjustable regulator to cover or partly cover openings when desired,
it can also be fixed the reverse way to allow the egress of foul air from
buildings.
Fig. 1 is a view of one form of my invention ready for fixing but with one side
omitted to more clearly show the partitions and openings which are the chief
novelties in my invention.
Fig. 2 is a view with side omitted and upper part raised to show partitions.
Fig. 3 is a section when fixed in chimney breast.
The box can be made of any convenient shape in one or more parts and the
partitions can be attached to or form part of any portion of the box but 1 prefer
to make the box in two parts with partitions arranged as shown on the accompanying
drawings.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
For curing smoky chimneys and for ventilating purposes, appliance having
partitions and openings substantially as herein set forth.
