IMPROVEMENTS IN VESSELS FOR CONTAINING HOT LIQUIDS
Year: 1869

page_text: LETTERS PATENT to Valentine Baker, of Aldershott, in the County
of Surrey, Colonel in the Army, for the Invention of "IMPROVEMENTS
IN VESSELS FOR CONTAINING HOT LIQUIDS."
Sealed the 30th July 1869, and dated the 3rd February 1869.
PROVISIONAL SPECIFICATION left by the said Valentine Baker at
the Office of the Commissioners of Patents, with his Petition, on the
3rd February 1869.
I, VALENTINE BAKER, of Aldershott, in the County of Surrey, Colonel
in the Army, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN VESSELS FOR CONTAINING HOT LIQUIDS," to be as follows:-
My Invention applies to cans for containing and conveying hot water,
teapots, and other vessels, and has for its object to retard the cooling of
the contents. For this purpose I construct the vessels with a double
casing having a space between the inner and outer casings, which may
contain air, or may be filled with imperfectly conducting material, such
as wool, hair, feathers, or the like. When the vessels have covers or
lide I make them also double with a space containing air or imperfectly

page_text: conducting material. When the vessels have a spout or tube I make it
good to the inner casing, passing it through the space between the
casings and the outer casing, so that it communicates with the inside
of the vessel only.
The casings may be made of metal, or one or both may be of earthen-
ware, glass, or other suitable material.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Valentine Baker in the Great Seal Patent Office
on the 3rd August 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, VALENTINE
BAKER, of Aldershott, in the County of Surrey, Colonel in the Army,
send greeting.
WHEREAS Her Most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Third day of February, in the 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 successors,
give and grant unto me, the said Valentine Baker, Her special licence
that I, the said Valentine Baker, my executors, administrators, and
assigns, or such others as I, the said Valentine Baker, ny 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
VESSELS FOR CONTAINING HOT LIQUIDS," upon the condition (amongst others)
that I, the said Valentine Baker, 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 1, the said Valentine Baker, do hereby

page_text: is to be performed, to be particularly described and ascertained in and
by the following statement:-
My Invention applies to cans for containing and conveying hot water,
teapots, and other vessels, and has for its object to retard the cooling of
the contents. For this purpose I construct the vessels with a double
casing having a space between the inner and outer casings, which may
contain air, or may be filled with imperfectly conducting material, such
as wool, hair, feathers, or the like. When the vessels have covers or
lids I make them also double with a space containing air or imperfectly
conducting material. When the vessels have a spout or tube I make it
good to the inner casing, passing it through the space between the
casings and the outer casing, so that it communicates with the inside
of the vessel only.
The casings may be made of metal, or one or both may be of earthen-
ware, glass, or other suitable material.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 represents a section of a pail constructed according to my
Invention. a is the interior, and 6 the outer casing, a space being left
between a and b, which may either contain air or may be charged with
loose non-conducting material, such as hair, feathers, or the like; c is
the lid, which I prefer to make double also.
Fig. 2 represents the section of a water can which may have a double
lid d hinged to cover the charging aperture; e is the spout, which passes
through the outer casing and the space and is made good to the inner
casing.
Fig. 3 represents a section of a teapot, and Fig. 4 the section of a coffee-
pot constructed according to my Invention. The spout f in Fig. 4 may
either be of single thickness, as represented at e in Figs. 2 and 3, or it
also may be double cased, as represented in Fig. 4.
Fig. represents a section of an earthenware vessel so constructed
that the inner and outer casings a and b form one continuous piece, the
space between them and under the bottom being left open to contain air.
The lid g may be of wood or of metal, doubled so as to contain a space,
as already described.
Having thus described the nature of my Invention, and in what manner
the same is to be performed, I would have it understood that I do

page_text: not confine myself to any particular forms of vessels constructed
according to my Invention, nor to any particular materials employed
in their construction.
In witness whereof, 1, the said Valentine Baker, have hereunto
set my hand and seal, this Third day of August, in the year of
our Lord One thousand eight hundred and sixty-nine.
VALENTINE BAKER. (L.S.)
