Year: 1855

page_text: LETTERS PATENT. to Angier March Perkins.. of Francis Street, Gray's
Inn Road, for the Invention of "IMPROVEMENTS IN WARMING BUILDINGS
AND APARTMENTS BY HOT WATER."
Sealed. the 3rd June 1856, and dated the 6th December 1855.
PROVISIONAL SPECIFICATION left by the said Angier March Perkins,
at the Office of the Commissioners of Patents;; with his Petition, on:
the 6th December 1855.
I, ANGIER MARCH PERKINS, of Francis Street, Gray's Inn Road, do hereby
declare the nature of the Invention for IMPROVEMENTS IN WARMING BUILDINGS
AND APARTMENTS BY HOT WATER" to be as follows:
This Invention consists in warming buildings and apartments by means of
an ordinary hot-water apparatus, combined with a high-pressure apparatus, or
apparatus in which water circulates in closed pipes; and I so combine these
apparatus that the coil of the high-pressure apparatus enters into and heats
the water in the boiler of the lower-pressure apparatus; and I would remark,
that the coil of the high-pressure apparatus may either be entirely enclosed
within the boiler of the low-pressure apparatus, or only partly so, the rest of
the coil being employed to assist the low-pressure apparatus in warming the
building or apartment.

by the said Angier March Perkins in the Great Seal Patent Office
on the 5th June 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ANGIER
MARCH PERKINS, of Francis Street, Gray's Inn Road, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of December, in the year of our Lord
One thousand eight hundred and fifty-five, in the nineteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Angier March Perkins, Her special licence that I, the said Angier
March Perkins, my executors, administrators, and assigns, or such others
as I, the said Augier March Perkins, 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 "IMPROVEMENTS IN WARMING BUILDINGS AND APARTMENTS BY HOT WATER," upon
the condition (amongst others) that I, the said Angier March Perkins, my exe-.
cutors 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.
NOW KNOW YE, that I, the said Angier March Perkins, 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:-
This Invention consists in warming buildings and apartments by means of
an ordinary hot-water apparatus, combined with a high-pressure apparatus, or
apparatus in which water circulates in closed pipes; and I so combine these.
apparatus that the coil of the high-pressure apparatus enters into and heats
the water in the boiler of the low-pressure apparatus; and I would remark,
that the coil of the high-pressure apparatus may either be entirely enclosed
within the boiler of the low-pressure apparatus, or only partly so, the rest of
the coil being employed to assist the low-pressure apparatus in warming. the.
building or apartment.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.

page_text: DESCRIPTION
DRAWING.
Figure 1 shows a side elevation, and Figure 2 a plan, of apparatus arranged
or combined according to my Invention. The object of this arrangement of
the hot-water apparatus is to combine a former Patent, for circulating water
in tubes closed in all parts, and the ordinary mode of circulating water in tubes
open to the external atmosphere; also in keeping down the temperature of
the former when necessary.
A, A, is the small pipe hot-water apparatus in its simplest form, as now
constructed; B, B, is an ordinary hot-water apparatus, open to the atmosphere,
divested of its boiler, for which the pipe C is a substitute, and as is now well
understood. It will be seen, that if the flow pipe of the "small pipe appa-
ratus" a be passed through the tube C. of the low-pressure or hot-water
apparatus, which is open to the atmosphere, the water in the latter apparatus
will be heated, by abstracting heat from the pipe a', which passes through it,
and which in its turn will be prevented from rising in temperature much above
the boiling point. Thus, a useful combination may be made when an ordinary
hot-water apparatus requires to be improved in heating power. When it is
desired simply to keep down the heat of the apparatus A, then the flow and
return pipe may be passed through a cistern of water, which may be used for
a bath or other domestic purposes.
Having thus described the nature of my said Invention, and the manner of
performing the same, I would have it understood that what I claim is, the mode
herein described of combining hot-water circulating apparatus, whereby a
system of closed circulating hot-water pipes is made the means of heating
the circulating water in an apparatus open to the atmosphere, and the heat
of the closed water-circulating apparatus is kept down to the temperature
desired.
In witness whereof, I, the said Angier March Perkins, have hereunto
set my hand and seal, this Fourth day of June, in the year of our
Lord One thousand eight hundred and fifty-six.
Witness,
S. CARPMAEL
