Year: 1862

page_text: LETTERS PATENT to Rudolf Zimara, of St. Petersburgh, in the Empire
of Russia, Engineer, for the Invention of "IMPROVEMENTS IN STOVES POR
HEATING AND VENTILATING BUILDINGS."
Sealed the 10th October 1862, and dated the 24th April 1862.
PROVISIONAL SPECIFICATION left by the said Rudolf Zimara at the
Office of the Commissioners of Patents, with his Petition, on the 24th
April 1862.
I, RUDOLF ZIMARA, of St. Petersburgh, in the Empire of Russia, Engineer,
do hereby declare the nature of the Invention for "IMPROVEMENTS IN STOVES
FOR HEATING AND VENTILATING BUILDINGS," to be as follows:-
This Invention has for its object improved arrangements of the fire-
places, flues, and air passages of stoves, for the purpose of heating and
ventilating buildings.
It is well known that in heating atmospheric air for the purpose of warmth
and ventilation, by causing it to pass in contact with heated metal, surfaces as
at present commonly practised, that the air so heated is greatly deteriorated in
quality, and one of the principal objects of my improvements in stoves is so to
construct and arrange the flues and air passages thereof that the air, in its

page_text: passage to the interior of the building, may be heated by passing through a
series of pipes or passages composed entirely of earthenware.
The following is a description of the manner in which I prefer to construct
a pneumatic stove or heating apparatus according to my Invention, although I
do not confine myself to this particular arrangement. A suitable furnace or
fire-place, with fire-bars and ash-pit closed by doors, is built and lined with
fire-brick or fire-clay, for the combustion of the fuel. The heat and products
of combustion. pass over a bridge or partition, and then descend and pass
underneath another partition, so as in a great measure to consume the smoke.
The heat and products then ascend and pass to and fro, or in a zig-zag
form through a series of horizontal and vertical flues or pipes constructed
entirely of earthenware, and thence away to the chimney. Around and in
contact with these heated flues or pipes a series of passages are arranged,
which communicate with the external air and the interior of the building,
where heat and ventilation are required. The furnace or fire-place, together
with the series of flues and air. passages, are enclosed by brickwork, placed by
preference in the basement of, the building,, and the atmospheric air, heated in
its passage through the earthenware air passages. is conducted, by pipes or
passages, and introduced by suitable outlets into the several chambers of a
building as required.; suitable pipes or, passages are arranged for conveying
the foul or vitiated air away from the interior of the building, and conducting
it into the ash-pit of the furnace or fire-place, so as to create a continuous
current. By this arrangement of heating and ventilating apparatus great
economy of fuel is obtained.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of April, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the

page_text: said Rudolf Zimara, Her special licence that I, the said Rudolf Zimara, my
executors, administrators, and assigns, or such, others as I, the said Rudolf
Zimara, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter during
5 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 "IMPROVEMENTS IN
STOVES FOR HEATING AND VENTILATING BUILDINGS," upon the condition
(amongst others), that I; the said Rudolf Zimara, my executors or admi-
nistrators, by an instrument in writing under my, or their, or one of their
hands, and seals, 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 months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Rudolf Zimara, do hereby declare the
nature of the 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 :-....
to This Invention has for its jobject improved arrangements of the fire-places,.
flues, and, air: passages, of stoves, for the purpose of heating and ventilating
buildings
It is well known that in heating atmospheric air for the purposes of warmth
and ventilation, by causing it to pass in contact with heated metal surfaces .as
at present commonly practiced, that the air so heated is greatly deteriorated in
quality, and one of the principal objects of my improvements in stoves, is so to
construct and arrange the flues and air passages, thereof that the air, in its.
passage to the interior of the building, may be heated by passing through a
series of pipes or passages composed entirely of earthenware..
:
The following is a description of the manner in which I prefer to construct
a pneumatic stove or heating apparatus. according to.my Invention, although I
do not confine myself to this particular arrangement. A suitable, furnace or
fire-place, with fire-bars and ash-pit closed by doors, is built and lined, with fire-
brick or fire-clay, for: the combustion of the fuel. The heat and products of
combustion pass over a bridge or partition, and then descend and pass under-
neath.another partition, so as, in a great, measure, to consume the smoke:. The
heat and products then ascend, and pass, to and fro, or, in a zig-zag form through
afseries of horizontal and vertical flues or pipes constructed entirely of earthen-

page_text: ware, and thence away to the chimney. Around and in contact with these
heated flues or pipes a series of passages are arranged which communicate
with the external air and the interior of the building, where heat and ventila-
tion are required. The furnace or fire-place, together with the series of flues
and air passages, are enclosed by brickwork, placed by preference in the base-
ment' of the building, and the atmospheric air, heated in its passage through
the earthenware air passages is conducted by pipes or passages, and introduced
by suitable outlets into the several chambers of a building as required ; suitable
pipes or passages are arranged for conveying the foul or vitiated air away
from the interior of the building, and conducting it into the ash-pit of the
furnace or fire-place, so as to create a continuous current. By this arrange-
ment of heating and ventilating apparatus great economy of fuel is obtained.
And in order that my Invention may be most fully understood, I will proceed
to describe the Drawing hereunto annexed.
DESCRIPTION OF THE DRAWING.
Figure 1 shews a plan in section; Figure 2 is a longitudinal section;
Figure 3 is a transverse section; and Figure 4 is an end view of a stove,
arranged and constructed according to my Invention.
(1) is the furnace or fire chamber; and (2) are the fire bars, upon
which the fuel is placed for heating the stove; (3) is a zig-zag flue or
passage for conducting the heat and products of combustion to the earthen-
ware. tubes or flues (4), which communicate with the chimney (5). The
air is heated in the chambers (6), as it comes from the outer atmosphere,
being conducted into the stove by the flues or passages (7). The impure
or vitiated air is withdrawn from the heated apartments by means of flues
or passages (8), which conduct it into the furnace to be consumed; (9)
are apertures giving access to the earthenware pipes or flues and passages
of the stove, for cleaning the same when required; (10) damper. to regulate
the ventilation of the heated apartments; (11) space to afford facility for
cleaning out the earthenware tubes or flues; (12) is a damper to cut off
the draught to the chimney; (18) are entrances to the chambers (6) of the
stove; (14) is the ash-pit; (15) ducts or channels, through which the warm
air passes out of the chambers of the stove; (16) the body of the stove or
fire-place.
Having thus described the nature of my Invention, and the best means I
am acquainted with for carrying the same into practice, I would have it
understood that I do not confine myself to the exact details herein described,

page_text: so long as the peculiar character of my Invention be retained; but what I
claim is, the arrangement and construction of stoves composed entirely of
brick and earthenware, for the purpose of heating and ventilating buildings, as
herein described.
In witness whereof, I, the said Rudolf Zimara, have hereunto set
hand and seal, this Twentieth day of September, in the year of our
Lord One thousand eight hundred and sixty-two.
