Year: 1882

page_text: LETTERS PATENT to Robert Walker Raphael, of Balnamore, Ballymoney, in
the County of Antrim, Ireland for an Invention of "AN IMPROVED SELF-
INDICATING TEA OR COFFEE URN, HEATING JACKET, AND FEED KETTLE
COMBINED
PROVISIONAL SPECIFICATION left by the said Robert Walker Raphael
at the Office of the Commissioners of Patents on the 29th August 1882.
ROBERT WALKER RAPHAEL, of Balnamore, Ballymoney, in the county of
Antrim, Ireland, "AN IMPROVED SELF-INDICATING TEA OR COFFEE URN, HEATING
JACKET, AND FEED KETTLE COMBINED
.
"
My said Invention has for its object the construction of apparatus for the
purpose of facilitating the preparation and pouring-out of tea or coffee at table in
an easy and convenient manner; and consists in forming a cylindrical-shaped
vessel, inside of which is arranged a second cylindrical-shaped vessel of smaller
dimensions than the first or outer vessel, and over the inner vessel a portion of the
outer one is arranged to receive a water-supply kettle, the bottom of which is
provided with two taps-one communicating with the inner vessel, and the other
with the annular space between the outer and inner vessels. In the inner vessel is
placed the tea or coffee, which being supplied with water from the supply kettle
overhead, as also the annular space between the outer and inner vessels, heat is
applied by means of a spirits lamp placed underneath the outer vessel, when the
water is boiled in said outer vessel, and communicating its heat to the tea or coffee
in the inner vessel acts on same in a grateful manner without boiling it or otherwise
deteriorating its quality.
Two taps are provided in the sides of the vessel by means of which hot water
may be drawn off into cups from the outer vessel, or tea or coffee from the inner
vessel. These taps are provided with only one delivery; and on each is arranged
a gauge glass for indicating the height or quantity of the liquid in each vessel.

ROBERT WALKER RAPHAEL, of Balnamoro, Ballymoney, in the County of
Antrim, Ireland, "AN IMPROVED SELF INDICATING TEA OR COFFEE URN, HEATING
JACKET, AND FEED KETTLE COMBINED
"
My said Invention has for its object the construction of apparatus for the
purpose of facilitating the preparation and pouring out of tea or coffee at table in
an easy and convenient manner; and consists in forming a cylindrical-shaped
vessel, inside of which is arranged a second cylindrical-shaped vessel of smaller
dimensions, and over these two vessels is arranged a water-supply kettle, the
bottom of which is provided with two taps, one communicating with the inner
cylindrical vessel, and the other with the annular space between the outer and inner
cylindrical vessels, which space constitutes a heating jacket. In the inner vessel is
placed the tea or coffee, which being supplied with water from the supply kettle
overhead, as is likewise the annular space referred to, heat is applied by means of
a spirit lamp placed underneath the outer vessel, when the water is boiled in the
said annular space; and, communicating its heat to the tea or coffee in the inner
vessel, acts on same in a grateful manner without boiling it or otherwise dete-
riorating its quality. Two taps are provided on the outside of the apparatus by
means of which hot water may be drawn off from the annular space and tea or
coffee from the inner-cylindrical vessel. These taps are provided with only one
delivery; and on each is arranged a gauge glass for indicating the height or quantity
of the liquids in each vessel.
In order that my said Invention may be more readily understood, I will describe
the accompanying drawings:-Fig. 1 is a front elevation of my improved tea urn
complete, and fig. 2, a vertical transverse section, showing the interior arrangement.
A. A. represents the annular space between the outer and inner cylindrical vessels,
or the heating jacket as hereinbefore described; and, B, the inner cylindrical vessel
in which is placed the strainer C. In the upper portion of the apparatus is shown
the water-kettle D provided with two taps, a and a¹, the former communicating
with the inner vessel, and the latter with the annular space or heating jacket.
These taps are operated by the handles a³ and a³ seen fig. 1, and by their means
water can be supplied at pleasure either to the inner vessel or to the heating jacket.
Through the taps b. and b¹. either water or tea may be drawn off at pleasure, both
taps having only one outlet as shown. These taps are provided with gauge
glasses c. c., which indicate the height of the liquids in the interior vessels of the
urn. Small taps are provided at d. d. for cutting off communication with the gauge
glasses in the event of their breaking; and a small cushion of India-rubber is intro-
duced at the top and bottom of these gauge glasses to allow for expansion.
F. represents the spirit lamp which burns inside the pedestal of the urn, and is.
entirely out of sight. The lamp is first placed on the table, and the urn placed
over it.
The following are some of the advantages afforded by this Invention :-
1st. The tea is infused better in this urn than by the usual method, as the inner
vessel containing same does not come in contact with the flame of the spirit-lamp,
it being surrounded with boiling water which prevents the tea from boiling,
while it is kept in the hottest possible state.
2nd. It is easy to replenish the tea-pot or heating jacket with water by simply
turning the taps a. and a¹; and it is not necessary to look into the urn while water

page_text: being poured in, as the gauge glasses indicate the quantity of liquid within, as
likewise the strength of the tea.
3rd. The strainer placed inside the tea-pot prevents any leaves or sediment
passing into the cups, and thus the necessity of using a slop basin is dispensed
with.
4th. The reservoir kettle can be lifted away at pleasure, and refilled without
removing the urn from the table, and
5th. By the combined arrangement of this urn, tea can be infused to a greater
strength, thereby holding out longer against the diluting influence of the hot water
to such a degree as to afford many cups-full without replenishing the tea pot.
Having thus described the nature of my said Invention, and the manner of
applying the same in practice, I would have it understood that what I consider
novel and useful, and therefore claim as the Invention to be secured to me by the
hereinbefore in part recited Letters Patent is
1st. The combination formed by the arrangement of an outer and inner cylindrical
vessel provided with a water kettle or reservoir at the top, substantially for the
purpose and in the manner specified and set forth.
2nd. The combination formed by the taps b and b', communicating with the
two cylindrical vessels, and provided with only one outlet, substantially for the
purpose described and illustrated in accompanying drawings.
3rd. The combination formed by the taps b and b' with the gauge glasses c. c.
substantially for the purpose specified and set forth in accompanying drawings,
In Witness whereof I, the said Robert Walker Raphael, have hereunto set my
hand and seal this Twenty-fourth day of February, in the year of Our Lord,
One thousand, eight hundred and eighty-three.
