A NEW OR IMPROVED COFFEE POT
Year: 1868

page_text: LETTERS PATENT to John Denley, of Cheltenham, in the County of
Gloucester, Tin Plate Worker, for the Invention of "A NEW OR
IMPROVED COFFEE POT."
Sealed the 13th April 1869, and dated the 14th October 1868.
PROVISIONAL SPECIFICATION left by the said John Denley at the
Office of the Commissioners of Patents, with his Petition, on the
14th October 1868.
I, JOHN DENLEY, of Cheltenham, in the County of Gloucester, Tin
Plate Worker, do hereby declare the nature of the said Invention for
"A NEW OR IMPROVED COFFEE POT," to be as follows:-
This Invention relates to the construction of a new or improved coffee
pot whereby the strained infusion of coffee may be poured off without
the risk of the unstrained liquid overflowing from the upper division of
the coffee pot. I propose to form the upper and removeable division of
the ordinary cylindrical form to fit the exterior body, and to attach to
its lower edge an internal circular flange or annular ring, beneath

page_text: which and in contact therewith a diaphragm of suitable fabric is
stretched or attached by means of a small projecting rim around the
exterior edge of the cylinder. The interior space of the cylinder contains
a conical metal strainer perforated with a number of fine holes, the
base of the cone being soldered to the inner edge of the annular ring;
the top of the cylinder is closed by another ornamental ring and by
a hinged lid fitting its internal diameter. By these arrangements the
infusion is first strained by the metallic cone, and, secondly, by the
diaphragm; and when the strained portion is being poured off the
remaining unstrained portion is prevented from escaping from the upper
chamber of the coffee pot, and will speedily follow through the strainers
as the lower portion is poured off.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Denley in the Great Seal Patent Office on the
14th April 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
DENLEY, of Cheltenham, in the County of Gloucester, Tin Plate Worker,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of October, in the year
of our Lord One thousand eight hundred and sixty-eight, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Jolin Denley, Her special licence that I, the
said John Denley, my executors, administrators, and assigns, or such
others as I, the said John Denley, 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 NEW OR IMPROVED COFFEE POT,"
upon the condition (amongst others) that I, the said John Denley,
my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and scals, 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

page_text: .
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 John Denley, do hereby declare the
nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement:-
My Invention relates to the construction of a new or improved coffee
pot whereby the strained infusion of coffee may be poured off without
the risk of the unstrained liquid overflowing from the upper division of
the coffee pot. I propose to form the upper and removable division of
the ordinary cylindrical shape to fit the exterior body, and to attach to
its lower edge an internal circular flange or annular ring, beneath which
and in contact therewith a diaphragm of suitable fabric is stretched or
attached by means of a small projecting rim around the exterior edge
of the cylinder. The interior space of the cylinder contains a conical
metal strainer perforated with a number of fine holes, the base of the
cone being soldered to the inner edge of the annular ring; the top of
the cylinder is closed by another ornamental ring and by a hinged lid
fitting its internal diameter. By these arrangements the infusion is first
strained by the metallic conc, and, secondly, by the diaphragm; and
when the strained portion is being poured off the remaining unstrained
portion is prevented from escaping from the upper chamber of the coffee
pot, and will speedily follow through the strainers as the lower portion
is poured off.
In order that my said Invention may be completely understood I
annex the accompanying Drawing, which represents a vertical section
of the coffee pot.
a is the outer cylinder, and 6 the internal moveable strainer, having
the perforated dome c in the centre, and being surrounded at the lower
edge with a fabric c', which is tightened around the lower projecting
ledge of the plate 6'. The cylindrical strainer is formed in one piece
with the top d, having the lid e pivoted thereto, so that by the handle f
the strainer can he lifted out of the pot when necessary, its position
being steadied by a projection on the interior of the pot and by a slot
or groove in the strainer. The coffee is placed in the receptacle b, and
boiling water is poured thereon; the infusion then passes through the
perforated dome, carrying some of the particles of the coffee on to the
fabric c', which prevents them from passing into the lower portion of

page_text: the cylinder, and thus a clear infusion is obtained possessing all the
strength and flavor of the coffee. Or the fabric may be carried below
the bottom of the strainer and stretched on a circular wire frame fixed
to the metal strainer, as shewn in dotted lines c².
Having now described the nature of my said Invention, and the
manner in which the same is to be performed, I would remark in con-
clusion that I do not limit myself to the exact details and configuration
of parts which I have expressed and shewn, as the same may obviously
be varied or modified without departing from the principle of the
Invention; but what I claim and desire to be secured to me by the
herein in part recited Letters Patent is, the application of the strainer b
and dome c in connection with the fabric c¹ to coffee pots, substantially
as and for the purposes herein specified.
In witness whereof, I, the said John Denley, have hereunto set my
hand and seal, this Seventeenth day of March, in the year of our
Lord One thousand eight hundred and sixty-nine.
