Year: 1869

page_text: LETTERS PATENT to Edwin Round, of Sheffield, in the County of
York, Silver Plate Manufacturer, for the Invention of "IMPROVE
MENTS IN VESSELS FOR HOLDING AND COOLING OR WARMING FLUIDS OR
SOLIDS."
Sealed the 22nd June 1869, and dated the 17th February 1869.
PROVISIONAL SPECIFICATION left by the said Edwin Round at the
Office of the Commissioners of Patents, with his Petition, on the
17th February 1869.
I, EDWIN ROUND, of Sheffield, in the County of York, Silver Plate
Manufacturer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN VESSELS FOR HOLDING AND COOLING OR WARMING FLUIDS OR
SOLIDS," to be as follows :-
The improvements consist in constructing vessels with an inner vessel
or receptacle and leaving a space or spaces between them, into which ice
or a cooling matter or mixture may be introduced for the purposes of
cooling, and hot water or a warming matter for the purposes of warming,
1

page_text: any fluid or material that may be put in the inner receptacle and be
kept distinct therefrom, and in furnishing the (outer) vessel with a false
or double bottom and leaving a space between them, the false or upper
bottom being furnished with suitable holes or outlets for drawing off the
water or liquid from the ice or cooling matter when necessary, and so
keeping the ice or cooling matter when applied to the space between
the outer vessel and its receptacle or inner vessel free from wet or too
much moisture, whereby it and a low temperature is longer preserved.
And when a top or cover is used to such vessels constructing such top
or cover hollow or double, and so leaving an air space between them,
the outer or upper part being furnished with suitable holes for the
admission of air.
The mode of performing the Invention is to make the vessels above
mentioned of glass, earthenware, india-rubber, gutta percha, metal, or
other convenient material, either wholly or partially of one and partially
of another, of any convenient size and shape. The space between the
vessels, as above described, and the space between the false and true
bottom may be conveniently supplied with communications by means of
holes of suitable size for the admission of ice, &c., or hot water, &c., and
for the purposes of extracting same and drawing off the liquid cooling
or heating matter when needed, also for cleaning purposes, and if
needed each space may be supplied with vent holes and vent taps.
the true bottom of the vessel may be furnished when intended to be used
as a jug or mug or for like purpose with a perforated hollow plug of
any convenient size, made to screw in and out of the true bottom, and
of sufficient' depth to plug the hole in the false bottom as well, the
perforations in the plug being from and through the top and sides, and
not in the bottom.
And

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventeenth day of February, in the year
of our Lord One thousand eight hundred and sixty-nine, in the thirty-
first year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Edwin Round, Her special licence
that I, the said Edwin Round, my executors, administrators, and
assigns, or such others as I, the said Edwin Round, 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
VESSELS FOR HOLDING AND COOLING OR WARMING FLUIDS OR. SOLDS," upoD
the condition (amongst others) that I, the said Edwin Round, 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Edwin Round, 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, that is to say :-
The improvements consist in constructing vessels with an inner
vessel or receptacle and leaving a space or spaces between them, into
which ice or a cooling matter or mixture may be introduced for the
purposes of cooling, and hot water or a warming matter for the purpose
of warming, any fluid or material that may be put in the inner receptacle
and be kept distinct therefrom, and in furnishing the (outer) vessel with
a false or double bottom and leaving a space between them, the false or
upper bottom being furnished with suitable holes or outlets for inserting
the cooling or warming material and for drawing off the water or liquid
from the ice or cooling matter when necessary, and so keeping the ice or
cooling matter when applied to the space between the outer vessel and
its receptacle or inner vessel free from wet or too much moisture, whereby
it and a low temperature is longer preserved. And when a top.or cover

page_text: is used to such vessels constructing such top or cover perforated and
made hollow or double, and so interposing an air space, the outer or
upper part being furnished with suitable holes for the admission of air.
The mode of performing the Invention is to make the vessels
above mentioned of glass, earthenware, india-rubber, gutta percha
metal, or other convenient material, either wholly or partially of one
and partially of another, of any convenient size and shape. The space
between the vessels, as above described, and the space between the false
and true bottom inay be conveniently supplied with communications by
means of a hole or holes of suitable size for the admission of ice or hot
water, and for the purposes of extracting same and drawing off the liquid
cooling or heating matter when needed, also for cleaning purposes, and
if needed each space may be supplied with vent holes and vent taps.
And the false bottom of the vessel may be furnished when intended to be
used as a jug or mug or for like purpose with a moveable perforated
plug or diaphragm plate, of any convenient size and shape, made to
screw or fit in it; or the diaphragm plug or plate may be fixed to the
top, or in the upper part of the moveable true bottom, or in any con-
vonient way, so that the diaphragm plug may act as a strainer or
drainer, and sufficient space be left underneath it in the moveable true
bottom for the purpose intended.
The accompanying Drawing illustrates the Invention as applied to
jugs, mugs, or tankards.
Figure 1 is a perspective elevation shewing the vessel separated from
the bottom with the diaphragm strainer D in place; Figure 2, a
perspective elevation shewing the diaphragm D detached; Figure 3, a
sectional elevation of the vessel with the moveable bottom or catch
receptacle fitted on and in position for use.
In the above Figures A is the inner vessel or receptacle; B, the
space between it and the outer vessel; C, the perforated double cover;
C*, holes in same; D, the perforated diaphragm strainer; E, the
moveable catch receptacle bottom; F, hole for removing or inserting
contents, and for receiving the securing plug in the handle Fx; G, G,
hinges and pins for securing the vessel, the diaphragm, and the catch
receptacle bottom together. When it is intended to use hot water the

page_text: diaphragm D may be removed, and the hot water introduced through
the hole F (the jug being turned upside down for the purpose).
In witness whereof, I, the said Edwin Round, have hereunto set
hand and seal, this Seventeenth day of June, in the year of
our Lord One thousand eight hundred and sixty-nine.
