IMPROVEMENTS IN APPARATUS FOR HEATING WATER FOR WARMING GREENHOUSES AND OTHER BUILDINGS, AND FOR OTHER PURPOSES
Year: 1869

page_text: LETTERS PATENT to Thomas Amies, of Peterborough, in the County
of Northampton, for the Invention of "IMPROVEMENTS IN APPARATUS
FOR HEATING WATER FOR WARMING GREENHOUSES AND OTHER BUILDINGS, AND
FOR OTHER PURPOSES."
Sealed the 25th September 1869, and dated the 17th April 1869.
PROVISIONAL SPECIFICATION left by the said Thomas Amies at the
Office of the Commissioners of Patents, with his Petition, on the
17th April 1869.
I, THOMAS AMIES, of Peterborough, in the County of Northampton,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN APPARATUS FOR HEATING WATER FOR WARMING GREENHOUSES AND OTHER
BUILDINGS, AND FOR OTHER PURPOSES," to be as follows:-
This Invention has for its object to enable gas to be used more
economically than heretofore for heating water for hot-water apparatus
for warming greenhouses and other buildings, or for baths or other
purposes.

page_text: For this purpose I form the boiler of the apparatus of a vertical water
space enclosing three sides of a rectangle, thus the fourth side of
the rectangle being merely closed in by a door. At the top of the boiler
the three-sided vertical water space opens into a horizontal water space
which forms the top of the boiler. Below the bottom of the boiler is
placed a gas burner, and the products of combustion as they rise up
from it are caused to pass in a zig-zag direction between horizontal
water spaces which project out alternately from the opposite sides of the
vertical three-sided water space, and these horizontal water spaces extend
nearly from the one side to the other. These horizontal water spaces
are made of sheet metal bent over in the middle, thus
and they
are each connected by rivetting and soldering to one of the side water
spaces and also to the back water space. A small chimney is carried up
through the water space which forms the top of the boiler, and the
products of combustion are led off through this chimney. Boilers so
formed I place on to a cast-iron stand, through one or more sides of
which are perforations to admit air to the gas burner. The sides of the
boiler I also enclose with ornamental plates of cast iron, which are
secured at the bottom to the cast-iron stand and at the top to a cast-iron
cover by which the top of the boiler is covered over. In one of the side
plates is a door, by opening which the horizontal water spaces of the
boiler may be got at and cleaned externally.
Boilers of this description may be used for heating any suitable
arrangement of hot-water pipes, but I prefer to use it with apparatus
composed of two hollow standards of cast iron connected together at a
distance apart from one another by four or other number of horizontal
pipes. The boilers may also, as above stated, be used for heating water
for other purposes.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Amies in the Great Seal Patent Office on
the 16th October 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
AMIES, of Peterborough, in the County of Northampton, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventeenth day of April, in the

page_text: year of our Lord One thousand eight hundred and sixty-nine, in the
thirty-second year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Thomas Amies, Her special
licence that I, the said Thomas Amies, my executors, administrators,
and assigns, or such others as I, the said Thomas Amies, 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
APPARATUS FOR HEATING WATER FOR WARMING GREENHOUSES AND OTHER
BUILDINGS, AND FOR OTHER PURPOSES," upon the condition (amongst others)
that I, the said Thomas Amies, 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.
NOW KNOW YE, that I, the said Thomas Amics, 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 has for its object to enable gas to be used more
economically than heretofore for heating water for hot-water apparatus
for warming greenhouses and other buildings, or for baths or other
purposes. For this purpose I form the boiler of the apparatus of a
vertical water space enclosing three sides of a rectangle, thus the
fourth side of the rectangle being merely closed in by a door. At the
top of the boiler the three-sided vertical water space opens into a
horizontal water space, which forms the top of the boiler. Below the
bottom of the boiler is placed a gas burner, and the products of com-
bustion as they rise up from it are caused to pass in a zig-zag direction
between horizontal water spaces, which project out alternately from the
opposite sides of the vertical three-sided water space, and these horizontal
water spaces extend nearly from the one side to the other. These
horizontal water spaces are made of sheet metal bent over in the middle,
thus, and they are each connected by rivetting and soldering to

chimney is carried up through the water space which forms the top of
the boiler, and the products of combustion are led off through this
chimney. Boilers so formed I place on to a cast-iron stand, through
one or more sides of which are perforations to admit air to the gas
burner. The sides of the boiler I also enclose with ornamental plates of
cast iron, which are secured at the bottom to the cast-iron stand, and
at the top to a cast-iron cover, by which the top of the boiler is covered
over. In one of the side plates is a door, by opening which the
horizontal water spaces of the boiler may be got at and cleaned exter-
nally. Boilers of this description may be used for heating any suitable
arrangement of hot-water pipes, but I prefer to use it with apparatus
composed of two hollow standards of cast iron connected together at a
distance apart from one another by four or other number of horizontal
pipes; the boilers may also, as above stated, be used for heating water
for other purposes.
And in order that my said Invention may be most fully understood
and readily carried into effect I will proceed to describe the Drawings

page_text: and from the system of pipes or other arrangement in which it is
required to circulate. c is a stand on which the casing a and parts
connected therewith are supported; air is allowed to enter it at c¹
through a regulating damper to supply air to the gas which is burnt
from the burner d; e is a door enclosing the double casing a at the
front; it is usually kept closed, but is opened for lighting the gas.
The casing a may be surrounded on its three sides and at the top by an
ornamental open screen of cast iron.
The apparatus in which the hot water circulates may be varied in
construction as represented in the Drawing; it consists of four large
cast-iron pipes f, f, held at their ends in sockets on two hollow
standards 9, 9. These standards are connected by union joints with
the tubes b, b, and the whole arrangement is kept filled with water from
vases h, h, at the top of the standards.
In witness whereof, I, the said Thomas Amies, have hereunto set
my hand and seal, this Fifteenth day of October, in the year of
our Lord One thousand eight hundred and sixty-nine.
THO. AMIES. (L.S.)
