CERTAIN IMPROVEMENTS ON URNS TO BE USED FOR TEA, COFFEE, AND OTHER PURPOSES
Year: 1835

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
JERVIS TUCKER, of Trematon Hall, in the County of Cornwall, Esquire, send
greeting.
WHEREAS His present most Excellent Majesty King William the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twenty-second day of January, in the fifth year of His reign,
did, for Himself, His heirs and successors, give and grant unto me, the said
John Jervis Tucker, His especial licence, full power, sole privilege and
authority, that I, the said John Jervis Tucker, my exors, adñiors, and assigns,
or such others as I, the said John Jervis Tucker, my exors, adññors, or assigns,
should at any time agree with, and no others, from time to time and at all
times during the term of years therein expressed, should and lawfully might
make, use, exercise, and vend, within England, Wales, and the Town of
Berwick-upon-Tweed, my Invention of "CERTAIN IMPROVEMENTS ON URNS
TO BE USED FOR TEA, COFFEE, AND OTHER PURPOSES;" in which said Letters
Patent is contained a proviso that I, the said John Jervis Tucker, shall cause
a particular description of the nature of my said Invention, and in what
manner the same is to be performed, to be inrolled in His said Majesty's High
Court of Chancery within six calendar months next and immediately after
the date of the said in part recited Letters Patent, as in and by the same,
reference being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the
said John Jervis Tucker, do hereby declare the nature of my Inven-
tion, and the manner in which the same is to be performed and carried

page_text: into effect, are fully described and ascertained in and by the following descrip-
tion thereof, reference being had to the Drawing hereunto annexed, and to the
figures and letters marked thereon (that is to say):-
My Invention consists in applying, within an ordinary table urn, a vessel
having an opening in order to admit the hot water passing freely into the
internal vessel when required, such opening being capable of being closed by a
cock or valve when it is desired to prevent the hot water contained in the urn
coming into the internal vessel, the internal vessel being intended to receive
tea, coffee, cocoa, or chocolate, in order to be prepared as a beverage; and to
this internal vessel is connected a float, the stem of which passing through the
cover of the urn will indicate the quantity contained in the inner vessel.
Having thus stated the nature of my Invention, I will proceed to describe
the Drawing hereunto annexed, in which Figure 1 represents the section of an
urn having my improvements applied thereto. a, a, being the outer vessel
to contain water. b is the cover of the urn. c is an internal cover, which is
capable of being removed in order to allow of the urn being filled with water.
To this cover c is affixed the tube d to receive the ordinary heater. Within
the outer vessel a, a, is affixed the inner vessel e, e, the object of which will be
fully described hereafter. f is a cock having an opening into the inner
vessel e, e, and also another way into the outer vessel a, a. This will be more
evident on inspecting Figure 2, which represents the cock f in section,
9 being the opening or way to and from the inner vessel e, e, and h is the
opening or way to and from the outer vessel a, a. i is a plug or valve by
which the openings or passages g and h may be made to communicate with
each other. j is a plug to the passage g, and k is a plug to the passage h.
is a float or hollow ball, having the stem n affixed thereto; this ball is confined
within the tube o, there being openings for the passage of fluid, consequently
the ball m will rise and fall in proportion as the vessel e is more or less full.

Having now described the manner of applying my improvements to an urn,
I will describe the manner of using the same. I is a vessel which drops within
the vessel e, the vessel 7 being perforated at the bottom with numerous minute
holes or slits. In this vessel is to be placed a quantity of tea, coffee, cocoa,
or chocolate, according to the intended beverage to be produced. I will
suppose the urn to be in the following condition (that is to say), the heater in
its place, the outer vessel a full of boiling water, the whole of the plugs i, j, k,
being shut. On opening the plug i water will flow from the vessel a to the
vessel e, e, and the quantity indicated by the stem n rising through the cover
of the urn.
This stem n may be graduated or marked. By this means the
exact quantity of tea or other beverage may be produced without lifting the

page_text: The plug
cover to see the quantity admitted to the inner vessel e, e.
being
closed, the flow of water to the inner vessel e will be stopped. By this means
it will be evident that tea or other beverage may be produced within the urn;
and if it is desired to draw the same the plug j is to be opened, and the
tea will flow from the cock f; and it will be evident that if hot water be
required, then the plug k must be opened, and the same will flow from the
vessel a.
Having now described the nature of my Invention, and the manner of
constructing and using the same, I would have it understood that I confine my
claim of Invention to the application of the vessel e, e, within an ordinary urn,
such vessel having an opening or way to and from the vessel a, a. And also
in the application of a float, as above described.
In witness whereof, I, the said John Jervis Tucker, have hereunto set
my hand and seal, this Seventh day of July, in the year of our Lord
One thousand eight hundred and thirty-five.
