page_text: LETTERS PATENT to Robert Brown, of No. 12, Albion Street, Leeds,
in the County of York, Gentleman, for the Invention of "AN
IMPROVED VENTILATING STOVE."
Sealed the 24th May 1872, and dated the 13th January 1872.

PROVISIONAL SPECIFICATION left by the said Robert Brown at the
Office of the Commissioners of Patents, with his Petition, on the
13th January 1872.
I, ROBERT BROWN, of No. 12, Albion Street, Leeds, in the County
of York, Gentleman, do hereby declare the nature of the said Invention
for "AN IMPROVED VENTILATING STOVE," to be as follows:-
My Invention refers to a portable ventilating and warming apparatus
or stove constructed in iron, or any other suitable material. The stove
or apparatus is placed in any convenient part of the room or enclosure to
be ventilated, and connected with the outer atmosphere. The apparatus
is formed in three compartments. In the centre one is constructed an
inner chamber formed in such a manner so as to provide a channel from
the upper part of this compartment down and under the said inner
chamber, where there is an opening prepared for the admission of the
vitiated air.
'

page_text: There is an opening in the upper part of the central compartment of
the apparatus or stove to which is fixed a pipe carried up to within a
short distance of the ceiling of the room or enclosure to be ventilated,
and the vitiated air is conveyed or drawn down this pipe into the central
compartment of the apparatus through the channel, as before mentioned,
and from thence into the inner chamber where it is partly consumed by
the gas jet or jets, or any other suitable means that may be provided for
the purpose of maintaining combustion, and partly conveyed away by a
small pipe leading out of the inner chamber into the chimney, or some
other flue or opening provided for such purpose; the front panel of this
central compartment may be glazed, so that the light contained in the
inner chamber may be thrown into the room.
The two other side compartments are the receptacles for receiving and
warming the fresh air drawn into the said compartments by means of a
small pipe in each compartment connected with the outer atmosphere,
and when the air has become warmed by the heat generated in the
confined inner chamber it is admitted into the room or enclosure by
openings in the apparatus covered with wire gauze or perforated zinc, or
any other material suitable for the purpose of diffusing the air as it is
admitted into the room.
This apparatus may be constructed on a small or large scale, so that
it may be used for heating purposes as well as ventilating, to supersede
the ordinary fire; and in other cases it may be placed on a bracket for
the simple purpose of ventilating.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 2
filed by the said Robert Brown in the Great Scal Patent Office
on the 10th July 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
BROWN, of No. 12, Albion Street, Leeds, in the County of York, Gentle-
man, send grecting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her

page_text: give and grant unto me, the said Robert Brown, Her special licence
that I, the said Robert Brown, my executors, administrators, and
assigns, or such others as I, the said Robert Brown, my executors,
administrators, and assigns, should at any time agree with, and no
6 others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "AN IMPROVED VEN-
TILATING STOVE," upon the condition (amongst others) that I, the said
Robert Brown, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and scals, should
particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar
3 months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Robert Brown, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
My Invention refers to a portable ventilating and warming apparatus
or stove constructed in iron or any other suitable material. The stove
or apparatus is placed in any convenient part of the room or enclosure to
be ventilated, and connected with the outer atmosphere. The apparatus
is formed in three compartments. In the centre one is constructed an
inner chamber formed in such a manner so as to provide a channel from
the upper part of this compartment down and under the said inner
chamber, where there is an opening prepared for the admission of the
vitiated air.
There is an opening in the upper part of the central compartment of
the apparatus or stove, to which is fixed a pipe carried up to within a
short distance of the ceiling of the room or enclosure to be ventilated,
and the vitiated air is conveyed or drawn down this pipe into the central
compartment of the apparatus through the channel, as before mentioned,
and from thence into the inner chamber where it is partly consumed by
the gas iet or iets, or any other suitable means that may be provided for

page_text: other flue or opening provided for such purpose; the front panel of this
central compartment may be glazed, so that the lights contained in the
inner chamber may be thrown into the room.
The two other side compartments are the receptacles for receiving and
warming the fresh air drawn into the said compartments by means of a
small pipe in each compartment connected with the outer atmospherc,
and when the air has become warmed by the heat generated in the
confined inner chamber it is admitted into the room or enclosure by
openings in the apparatus covered with wire gauze or perforated zinc, or
any other suitable material, for the purpose of diffusing the air as it is
admitted into the room.
This apparatus may be constructed on a small or large scale, so that
it may be used for heating purposes as well as ventilating to supersede
the ordinary fire; and in other cases it may be 'placed on a bracket for
the simple purpose of ventilating, and in such case the three compart-:
ments, as heretofore mentioned as forming the apparatus, may be formed
by three glass cylinders placed together, and connected with the atmo-
sphere in the same way as before described.
The shaft or pipes for carrying off the vitiated air being carried up
from the bottom of the centre cylinder to within a short distance of the
ceiling, and in the same way the vitiated air is drawn down this pipe
into the centre cylinder, and is partly consumed by the gas, and partly
conveyed away by a pipe leading out of this inner cylinder into the
chimney or some other flue or opening provided for such purpose.
And in order that my said Invention may be fully understood I
shall now proceed more particularly to describe the same, and for that
purpose I shall refer to the several Figures on the annexed Sheet of
Drawings, the same letters of reference indicating corresponding parts
.in all the corresponding Figures.
Figure 1 of my Drawing represents a section of the ventilating
apparatus herein described. A is the inner compartment or chamber
into which the vitiated air is drawn; B, B, the outer chambers for
receiving the fresh air; C, the gas jet or jets; D, the pipe leading out of
the inner chamber or compartment into the flue; and E is the pipe or
shaft for conveying the vitiated air from the ceiling of the room down to
the gas jet or jets at the bottom of the apparatus through the channels
or spaces shown by the letters F, F, F; and G, G, are the openings
