IMPROVEMENTS IN APPARATUS OR ARRANGEMENTS POR WARMING AND VENTILATING BUILDINGS."
Year: 1867

page_text: LETTERS PATENT to William Woodcock, of Pimlico, in the County of
Middlesex, Engineer, for the Invention of "IMPROVEMENTS IN APPARATUS
OR ARRANGEMENTS POR WARMING AND VENTILATING BUILDINGS."
PROVISIONAL SPECIFICATION left by the said William Woodcock.at
the Office of the Commissioners of Patents, with his Petition, on the
25th September 1867.
I, WILLIAM WOODCOCK, of Pimlico, in the County of Middlesex, Engineer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
APPARATUS OR ARRANGEMENTS FOR WARMING AND VENTILATING BUILDINGS," to be
as follows:-
This Invention bas reference, in the first place, to certain improvements
applicable to stoves of the character of Gurney's stoves or any stove having a
number of plates from its outer surface with the plates vertical in a trough of
water, or any stove of analogous construction or action, and consists in
constructing the said stoves with feeding door, fire-door, and ash-pit door so
that they shall open into a stoking chamber or compartment which is other-
wise entirely separated from the stove, such stoking chamber or compartment

page_text: being wholly separated from the building to be warmed and ventilated; the
feeding door being so arranged as to exclude the outer air, but opening to any
pressure from within. Stoves may be, and I prefer that they should be, enclosed
in a chamber partially separated from the building to be warmed and ventilated,
that is, separated except as to its communication with the building, by means
of passages or flues for the conveyance of warm air from the stove to the
building, and the cooler air from the building to the stove.
Where practicable I add to the flue pipe of the stove at a convenient eleva-
tion a second or dummy stove, drums, horizontal lengths of pipes, or enlarged
pipes so as the more effectually to exhaust the heat therefrom, and to distribute
the same into the building to be warmed. By these arrangements I prevent
all dirt and dust from stoking and firing the stove from entering the building
to be warmed. I prevent (by the feeding door arrangement aforesaid) any
leakage of gases into the said building from down draught should any arise.
I make use of all available heat that can be spared from the flue pipes; and
by leaving a space above the stove in the stove chamber I cause a more rapid
passage of the air to be warmed over the surface of the stove.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Woodcock in the Great Seal Patent Office on the
23rd March 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
WOODCOCK, of Pimlico, in the County of Middlesex, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day of September, in the year of our
Lord One thousand eight hundred and sixty-seven, in the thirty-first year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Woodcock, Her special licence that I, the said William
Woodcock, my executors, administrators, and assigns, or such others as I,
the said William Woodcock, my executors, administrators, and assigns, should
at any time agree with, and no 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 "IM
PROVEMENTS IN APPARATUS OR ARRANGEMENTS FOR WARMING AND VENTILATING
BUILDINGS," upon the condition (amongst others) that I, the said William
Woodcock, my executors or administrators, by an instrument in writing under

page_text: 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 William Woodcock, 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:-
i
a
This Invention has reference, in the first place, to certain improvements
applicable to stoves of the character of Gurney's stoves, or any stove having
number of plates from its outer surface with the plates vertical in a trough of
water, or any stove of analogous construction or action, and consists in con-
structing the said stoves in the manner herein-after more particularly described
and shewn in the accompanying Drawings, with feeding door, fire door, and
ash-pit door so arranged that they shall open into a stoking chamber or
compartment which is otherwise entirely separated from the stove; such
stoking chamber or compartment being wholly separated from the building to
be warmed and ventilated. The feeding door is so arranged as to exclude
the outer air, but opening to any pressure from within; stoves may be, and I
prefer that they should be, enclosed in a chamber partially separated from the
building to be warmed and ventilated, that is, separated except as to its
communication with the building, by means of passages or flues for the
conveyance of warm air from the stove to the building, and the cooler air
from the building to the stove; where practicable I add to the pipe of the
stove at a convenient elevation a second or dummy stove, drums, horizontal
lengths of pipes, or enlarged pipes, so as the more effectually to exhaust the
heat therefrom and to distribute the same into the building to be warmed.
By these arrangements I prevent all dirt from stoking and firing the stove
from entering the building to be warmed; I prevent (by the feeding door
arrangement) any leakage of gases into the said building from down draught
should any arise; I make use of all available heat that can be spared from the
flue pipes, and by leaving a space above the stove in the stove chamber I
cause a more rapid passage of the air to be warmed over the surface of the
stove.
In the case of ordinary buildings it will be found that the arrangements
above described will cause a sufficient and proper amount of ventilation, but
where further ventilation is required I provide for it by making a channel
direct from the outer source of air supply the floor of the stove chamber.

page_text: In the accompanying Drawings my said improvements are shewn more
fully, and they will be more easily understood by reference thereto, similar
letters being used in all the Figures to denote corresponding parts.
In the accompanying Drawings A, where placed in the Drawings,
represents the room or building to be warmed outside the stove chamber;
B, where placed in the Drawings, represents the stove chamber shewn at the
side and on same level with the building to be warmed, but it may be placed
underneath or éven within it by an alteration of the various air channels to
correspond; C where placed in the Drawings represents the stoking chamber;
D, where placed in the Drawings, represents the stove; E represents the
cool air flues; F, where placed in the Drawings, represents the cool air
grating; G, where placed in the Drawings, represents doors and front of stove;
Hrepresents the flue pipe; I, where placed in the Drawings, represents the
drums; K, where placed in the Drawings, represents the horizontal pipes.
Having now described my Invention, I would have it understood that I
do not confine myself to the precise details herein set forth as these may be
varied without departing from the nature of my Invention; but what I
claim is the combination of parts forming my improved apparatus for warming
and ventilating buildings constructed and arranged substantially as herein
described.
In witness whereof, I the said William Woodcock, have hereunto set my
hand and seal, the Sixth day of March One thousand eight hundred
and sixty-eight.
WILLIAM WOODCOCK. (L.S.)
Signed, sealed, and delivered by the
above-named William Woodcock,
in the presence of
AUGUSTUS WOODCOCK,
Engineer's Clerk,
12, Abingdon St.,
Westminster.
