Year: 1863

page_text: LETTERS PATENT to Peter Rigby Wason, of Corwar House, near Dirvan,
Ayrshire, for the Invention of "IMPROVEMENTS IN APPARATUS USED FOR
Sealed the 31st May 1864, and dated the 8th December 1863.
PROVISIONAL SPECIFICATION left by the said Peter Rigby Wason at the
Office of the Commissioners of Patents, with his Petition, on the 8th
December 1863.
I, PETER RIGBY WASON, of Corwar House, near Dirvan, Ayrshire, do
hereby declare the nature of the Invention for "IMPROVEMENTS IN APPA-
RATUS USED FOR HEATING AND VENTILATING HORTICULTURAL BUILDINGS," to be as
follows:-
This Invention has for its object improvements in apparatus used for heating
and ventilating horticultural buildings. For these purposes an ordinary or
any suitable air-heating stove or apparatus is employed in order to heat the
air which is to be supplied to a house. The heated air is conducted into a
flue, which it is preferred should run from end to end of the house, though this
may be varied. The flue is constructed on or near the floor of the house, and
there are numerous small openings through the upper surface; or it may be at
one side of the flue, in order that the heated air supplied from the air-heating
apparatus to the flue may be diffused from end to end of the building. Covers
or valves are arranged so as to cover or close the openings at any part of the

page_text: flue. At the upper part of the house there are openings in connection with a
chimney or chimneys or otherwise for the passage away of air from the house,
and valves are used to regulate the outgoing air.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Peter Rigby Wason in the Great Seal Patent Office on the.
8th June 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PETER
RIGBY WASON, of Corwar House, near Dirvan, Ayrshire, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of December, in the year of our
Lord One thousand eight hundred and sixty-three, in the twenty-seventh year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Peter Rigby Wason, Her special licence that I, the said Peter
Rigby Wason, my executors, administrators, and assigns, or such others as I,
the said Peter Rigby Wason, my executors, administrators, and assigns, should
at any time agree with, and no others, from time to time and at all times there-
after 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 "IMPROVEMENTS
IN APPARATUS USED FOR HEATING AND VENTILATING HORTICULTURAL BUILDINGS,”
upon the condition (amongst others) that I, the said Peter Rigby Wason, my
executors or administrators, 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 per-
formed, 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 Peter Rigby Wason, 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 follow-
ing statement thereof, that is to say :-
This Invention has for its object improvements in apparatus used for heating
and ventilating horticultural buildings. For these purposes an ordinary or
any suitable air-heating stove or apparatus is employed in order to heat the
air which is to be supplied to a house. The heated air is conducted into a
flue, which it is preferred should run from end to end of the house, though

page_text: this may be varied. The flue is constructed on or near the floor of the house,
and there are numerous small openings through the upper surface; or it may
be at one side of the flue, in order that the heated air supplied from the air-
heating apparatus to the flue may be diffused from end to end of the building.
Covers or valves are arranged so as to cover or close the openings at any part
of the flue. The flue is by preference formed of brickwork covered over with
tiles perforated with numerous small holes up or through which the heated air
supplied to the flue passes into the house in numerous streams. This flue
should be near the front of the house. The passage of the streams of heated
air at any part of the flue may be for a time stopped or regulated by covering
one or more of the perforated tiles with a cover or covers of slate or other
material. It is desirable that the cross section of the flues should be of larger
area than the sum of all the openings through the perforated tiles, so that
there may be at all times a good supply of heated air from end to end of the
flue, as by such means, aided by the covers, the quantity of heated air introduced
into a house, and consequently the temperature of the atmosphere therein, may
be regulated. At the upper part of the house there are openings in connection
with the atmosphere for the passage away of air from the house, and valves
are used to regulate the outgoing air. At the back of the house is formed a
flue or passage leading to a chimney situated either at one end of the building
or intermediate of the two ends of the building; this chimney is for the purpose
of drawing the heated air along the flues; in this chimney is an opening with a
valve to regulate the speed by which the heated air is forced into the house
with nicety by means of the covers or valves to these outlets, and the direction
of the incoming streams of heated air which pass to the outlet flue will
depend on the use made of the covers or valves of the inlet and outlet flues
respectively.
In witness whereof, I, the said Peter Rigby Wason, have hereunto set
my hand and seal, this Seventh day of June, in the year of our Lord
One thousand eight hundred and sixty-four.
P. RIGBY WASON.
