Year: 1835

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EVATT WRIGHT, of Regent Street, in the City of Westminster, Gentleman,
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-seventh day of January, in the
fifth year of His reign, did, for Himself, His heirs and successors, give
and grant unto me, the said William Evatt Wright, His especial licence,
full power, sole privilege and authority, that I, the said William Evatt
Wright, my exors, admñňors, and assigns, or such others as I, the said
William Evatt Wright, my exors, adñiors, 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, exer-
cise, and vend, within England, Wales, and the Town of Berwick-upon-
Tweed, my Invention of "CERTAIN IMPROVEMENTS IN TEA AND COFFEE URNS:
AND TEA KETTLES;" in which said Letters Patent is contained a proviso that.
I, the said William Evatt Wright, 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 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 there-..
unto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William. Evatt Wright, do hereby declare the nature of my Invention, and

page_text: DESCRIPTION OF THE DRAWING.
Figure 1 represents the first improvement, which is applied to the heater of
urns, and consists in applying a nonconducting material at the upper part
which serves to prevent the heat ascending, and is thns forced to pass off
laterally, whereby it is more advantageously applied to the water contained
within the urn. a being the ordinary heater; b is the nonconducting material,
and for which I usually employ fire brick or fire stone moulded or cut to the
form required; c is a rod of wire screwed into the heater and passing through
the nonconducting material, having an eye or opening for the ring d. I would
remark that in addition to preventing the heat ascending, the heater is so
constructed that it may be handled at the part where the nonconducting
material is applied, and I wish it to be understood that in stating fire brick or
fire stone as the nonconducting material used by me, I do not confine myself
thereto, as other materials may be used provided they are not injured by the
heat to which they will be subjected. I do declare that my Invention, so far
as the improvements are applicable to the heaters of urns, consists in applying
a nonconducting material at the upper part of the heaters of urns, as above
described.
Secondly, my improvements on urns consists in applying an inner fixed
cover, whereby I am enabled to raise the water within the urn to several
degrees above boiling point, and thus keep water sufficiently hot for the
purpose of making tea for a much longer time than by ordinary urns, in the
covers of which there are openings cut to let off the steam generated by
the boiling water; but in order to prevent the possibility of accident I apply to
such fixed cover a safety valve.
Figure 2 shows the section of an urn having this second improvement
applied thereto; a being the vessel or urn, which may be of any figure or
shape desired; is the fixed cover having the tube c for the heater passing
through it, such tube being affixed to the cover b;e is the safety valve or
weighted cover to the opening e at which the water is poured into the urn.
And as a variation of the above plan, though producing the same effect,
the retention of heat, I apply an inner moveable and heavy cover to the urn
of a desirable weight (proportioned to the degree of steam), the said cover
acting as a valve; and I prefer to have a valve in this heavy cover by which

page_text: the water can be poured into the urn, and the steam, when too strong,
carried off.
My third improvement applies also to urns, and consists in constructing the
outer vessel of china or earthenware, by which means an urn may be made to
agree in appearance with the china or other cups, but such outer vessel of
earthenware or china is not intended itself to contain the water, but has an
inner vessel made of copper, tin, or iron, or other suitable metal fitted up
with heater, as shown in Figure 3, a being the outer vessel of earthenware
or china, which may be made to any desired device; 6 is an inner vessel of
metal to contain the water; c is a cock which, passing through the outer,
is made fast to the inner vessel, as shown in the Drawing; d is the earthen-
ware or china cover. It should be stated that the inner or water vessel may
be constructed similarly to the urns at Figure 2, or they may be plain
vessels with a moveable cover having a heater applied in order to continue
the supply of heat to the water; my third improvement consisting in super-
adding the outer vessel a, made of earthenware or china, to an inner vessel
which contains the water and heater, as above described.
My fourth Invention consists in applying a heater to the ordinary tea
kettle.
Figure 4 shows the section of a tea kettle. a is a tube passing to the
inner part thereof; b is the heater, which I prefer to be similar to that
described in Figure 1, but do not confine myself thereto, my fourth improve-
ment consisting in the application of the tube a to tea kettles to receive a
heater, as above described.
My fifth improvement consists in applying a heater to urns made of china
or earthenware on a small scale without any interiour of metal to hold the
water or coffee; though I prefer for this purpose a heater such has been
before described, I do not confine my claim to it.
Figure 5 shows a china urn in section; b, a metal tube moveable; d, hole
in the heater case is inserted; e is the hole through which the water is poured,
and which has a cover which acts as a valve for the escape of superfluous
steam.
In witness whereof, I, the said William Evatt Wright, bave hereunto
set my hand and seal, this Twenty-fifth day of July, in the year of our
Lord One thousand eight hundred and thirty-five.
