PROVISIONAL SPECIFICATION.
Improvements in Blowers and Draught Regulating Appliances for
Open Stoves.
I, JOHN WILLIAM MOTT, 284, High Street, Lewisham, S.E., Parochial Officer,
do hereby declare the nature of this invention to be as follows:-
It is made of two strips of iron plate on hinges (see letters A B & C) with
a½ inch round iron guard with thumb screw to regulate draught (see letter D).
The iron plates may be 1/16 or 1/8 inch thick and made to any size required, and
a or 3 inch flange may be turned down all round to strengthen plates. The
appliance produces slow combustion and throws back %10 of heat into the room
instead of escaping into the chimney. No fitting is required but merely to place
the appliance in position in the stove (see letter E.). In summer months it
could be entirely closed preventing rain and soot from falling into fire place.
Enormous save of fuel will be proved in large establishments where many fires
are used. Bedrooms and other rooms may be ventilated without any unpleasant
down-draught being experienced, present blowers have either to be wide open or
completely closed.
For repairs to defective stoves and brick work in chimney the appliance would
be invaluable.
The appliance is to be simply placed in the opening at the top of the stove,
and its upper portion allowed to drop towards the back of the chimney (see
letters F&G) so as to give sufficient ventilation for the escape of the smoke
through the chimney, at the same time retaining the heat in the room.
The appliance is specially adapted for asbestos in grates throwing the heat
nto the room, the fumes of gas into chimney.

I, JOHN WILLIAM MOTT, 284, High Street, Lewisham, S.E., Parochial Officer,
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:-
-
It is made of two strips of iron plate on hinges (see letters A, B & C) with a
inch round iron guard with thumb screw to regulate draught (see letter D).
The iron plates may be 1/16 or ½ inch thick and made to any size required
[Price 8d.]

The appliance produces slow combustion and throws back %10 of heat into the
room instead of escaping into the chimney. No fitting is required but merely
to place the appliance in-position in the stove (see letter E).
In summer months it could be entirely closed preventing rain and soot from
falling into fire-place. Enormous save of fuel will be proved in large establish-
ments where many fires are used. Bed rooms and other rooms may be ventilated
without any unpleasant down draught being experienced, present blowers have
either to be wide open or completely closed.
For avoiding the cost of repairs to defective stoves and brickwork in chimney
the appliance will be invaluable because such defects will be completely hidden
when the appliance is placed across the opening.
The appliance is to be simply placed in the opening at the top of the stove and
its upper portion allowed to drop towards the back of the chimney (see letters F
and G) so as to give sufficient ventilation for the escape of the smoke through
the chimney at the same time retaining the heat in the room.
The drawings above referred to are those filed with the Provisional Specification.
The method of placing the appliance in position in the stove is more fully
and clearly shown on the additional drawing submitted herewith and numbered 3.
The appliance is specially adapted for asbestos in grates throwing the heat into
the room while the gas fumes escape into the chimney.
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. That my invention is altogether original and as far as I can ascertain the
appliance has never before existed.
2. That the appliance is as described on Page 1° in this my Complete Speci-
fication vizt. It is composed of two strips of iron plate on hinges (see letters A,
B & C on drawing 1) with a 4 inch round iron guard with thumb screw to regu-
late the draught (see letter D, on drawing 2). That the iron plates may be 1/16
or inch thick and made to any size required, and a ¼ or 3 inch flange may
be turned down all round to strengthen plates. That no fitting is required but
merely to place the appliance in position in the stove (see letter E on drawing 2)
also the additional drawing numbered 3 submitted with this my Complete
Specification.
3. That the appliance is of a most simple character and its very simplicity
therefore needs protection.
JOHN WILLIAM MOTT.
