Sealed the 28th May 1861, and dated the 9th January 1861.
PROVISIONAL SPECIFICATION left by the said William Taylor at the
Office of the Commissioners of Patents, with his Petition, on the 9th
January 1861.
I, WILLIAM TAYLOR, of Nursling, near Southampton, in the County of Hants,
Gentleman, do hereby declare the nature of the said Invention for "A COMBINED
HEATING AND VENTILATING PIPE TO BE MADE ELLIPTICALLY OR OTHERWISE," to be
as follows:-
The patentee proposes to construct or make such pipes with a partition,
whereby two distinct chambers will be formed, one chamber to be filled with a
heating medium, as hot water, steam, or gas, and the other chamber with air.
The pipes are made of any malleable metal, or cast iron, of any shape, with
a partition cast inside, and are connected by suitable sockets, bends, and
outlets for connecting them. The ends of the water, steam, or gas chamber
pipes will be left open, and the ends of the air chamber will be closed, so
that each length of pipe will have a complete closed air chamber, which
will be heated by the water, steam, or gas chamber. There is a pipe
inserted in the air chamber to supply fresh air, and another pipe or pipes

page_text: with taps to convey it where required, or the air chamber can be perforated
for the same purpose.
The pipes in question may be used for the purpose of heating apart from
ventilating purposes, and for the purpose of being used in mines or other places
removed far from the outer atmosphere; other pipes will be used to convey
fresh air to supply them. The patentee also claims the method of manufac-
turing such pipes and connections by using sheet iron or sheet galvanized iron,
zine, copper, or other suitable material (and if made of cast iron, by having
the partition cast in the said pipes), by bending the same round proper
mandrils and double lapping the joints, and then brazing, soldering, and
riveting the same with suitable machinery.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Taylor in the Great Seal Patent Office on the
5th July 1861.
_TO_ALL_TO_WHOM THESE PRESENTS SHALL COME, I, WILLIAM
TAYLOR, of Nursling, near Southampton, in the County of Hants, Gentleman,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of January, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me
the said William Taylor, Her special licence, that I, the said William
Taylor, my executors, administrators, and assigns, or such others as I,
the said William Taylor, 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
"A COMBINED HEATING AND VENTILATING PIPE TO BE MADE ELLIPTICALLY OR
OTHERWISE," upon the condition (amongst others) that I, the said William
Taylor, 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 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.

page_text: NOW KNOW YE, that 1, the said William Taylor, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement and by this present instrument in writing, reference being had to
the Drawing hereunto annexed, and in which said Drawing similar parts are
marked and referred to by similar letters or figures (that is to say) :-
COMBINED HEATING AND VENTILATING PIPE.
My Invention consists of a pipe made in any shape or form, and of any
length or size, and of any kind of material that is suitable, such as cast,
mallable, or sheet iron, copper, tin, zinc, or anything that will contain heated
water, steam, or gas, &c., and having in it at least two compartments so as to
contain one part hot water, steam, gas, or any other heating medium, and
the other is an air chamber or compartment. To accomplish this I cast a
partition or division in a cast-iron pipe, or I form an air chamber on the
outside instead of the inside of the pipe, as shewn in the several figures
of the annexed plan A, representing the atmospheric air B, hot water, or any
heating medium; the ends of the part of the pipe containing the heating medium
is left open so as to keep up a continual flow and return, but the ends of
the air chamber are completely closed. The air chamber can be made or
divided into as many compartments as is required. Each air chamber has
an inlet to admit the fresh air, and an outlet to convey or distribute it
where required. The pipes can be made to be put together in the common
way of jointing, or with flexible joints, so as to be moved about in mines, ships,
holds, or any place requiring it, having wheels to move on if required. All the
bends, connexions, and requisite parts are made suitable for the different form
of pipes, the air or ventilating chamber or chambers, if not cast on the pipe,
can be made in any form, and fastened to the pipe afterwards, or one pipe can
be put into the other, or made in any way, so long as there is an air chamber
heated by the heating medium in connexion with it.
Another form of pipe on the plan has three chambers or compartments,
the middle one of which is stopped at the ends so as to form an air chamber,
as before described, which is heated by the heating medium on each side,
and being divided by this air chamber, is made to form a flow and return pipe in
tself so it needs but one pipe to both heat and ventilate a room. I take a
piece of copper, sheet iron, zinc, tin, or any suitable material and bend it over a
mandril the required form or shape, I then bend another piece suitable for
he inside or air chamber, which I put into the other and rivet the whole
together, as shown in plan No. 1. The section of pipe shown in the plan

page_text: No. 1 is made similar, but having but one division forming two chambers,
so it has one air and the other any heating medium, and has to be continued from
the flow arm of the boiler round to the return in the same way as an ordinary pipe.
No. 3 on the plan represents a section of pipe which is adapted to be used in
place of skirting board round a room, and contains both a flow and return
pipe and ventilating chamber in the one pipe, it is made to show a per-
foration in the air chamber so as to admit the fresh and heated air at once
into the room.
I have before described there must be an inlet and outlet in each air cham-
ber, I will now describe the action of it:-I form a connexion from any place
the air is required to be taken from with the hot-air chamber near the end; this
can be done by common iron pipes jointed together, or by constructing a flue
with bricks, or of common pipes, or any suitable way, near the other end of
the air chamber. I have an outlet as shown in plan, Figure No. 1, C being
the inlet, D the outlet. To this outlet a pipe or branch pipes are inserted or
united to the chamber, which is used to convey the heated fresh air where
required. Taps can be used for the purpose of regulating the quantity or turning
it from one branch pipe to another, and so as to both regulate the temperature-
and cause a free circulation of pure air at the same time. The fresh air rushes
in to supply the partial vacuum caused by the escape of the heated air through
the outlet, as described, into the place to be warmed.
I claim the method of supplying fresh and heated air to any place whatever
by means of an apparatus constructed in the manner described above, by which
the fresh air passes through a heated chamber, the heat of which is kept up by
a pipe containing the heating medium.
In witness whereof, I, the said William Taylor, have hereunto set
my hand and seal, this Fourth day of July, in the year of our Lord
One thousand eight hundred and sixty-one.
Signed and sealed by the said William
Taylor, in the presence of
THOMAS WESTALL, Solicitor,
3, South Square, Gray's Inn.
