Improvements in Tea Urns and similar Vessels.
AUGUSTE CAMILLE, Drysalter etc., 43 Manor Place Walworth London S.E.
do hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
The great object of this invention is to prevent decomposition of liquified food
by the substitution of covers (of which the inner surface in immediate proximity
with the liquors) consists of enamelled earthenware, enamelled iron, or similar
materials that remain unaffected under the different conditions of heat, evolution of
steam, and prolonged contact with various kinds of humid bodies. The moisture
deposited on the inner surface of the lid-through the fractional evolution of
moisture in the ebullition of the liquors contained in the earthenware jar-is by
this discovery enabled to disappear into a channel or hollow tube, provided round
the inner extremity of the lid, and thence into a tube proceeding to any desirable
part of the exterior of the urn or similar apparatus.
The drawings annexed represent a sectional view of an ordinary tea urn with the
improvement applied to the cover.
A. is an earthenware jar holding the liquid food.
B. is the water jacket, the water in which is intended for indirectly heating
contents of A.
C. represents a cover or lid to which the invention is attached.
D. is the water spout for filling space B.
E. shows an outline of an ordinary tap.
F. indicates the position of the gas jet for heating contents of space B. and A.
a. (which is part of the invention) represents an earthenware or enamelled iron
plate, resting upon a circular projection b., which secures the plate through three
equidistant grips, and can be removed at will.
b. is a circular channel or gutter of tinned or enamelled metal, which collects all
the moisture deposited, the latter being allowed to vanish through a tube leading to
exterior of the apparatus. It can either be affixed to the steadying rim c., which
drops into the urn, or in a position above that as shown on drawing.
d. is a screw or pin (of which there are four) for fastening channel b.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is.
1. That by application of my cover or lid-constructed on the principle of an
ordinary still the more or less rapid deterioration of tea, coffee, cocoa, chocolate,
and similar liquors used for the sustenance of the human body are infinitely
preserved in a healthy and palatable condition by the timely abstraction of the
humid bodies evolved through the ebullition of the liquors contained in the
earthenware jar.
2. That injurious effects would even be avoided, were part of these condensed
bodies returned into the earthenware jar, through the innocuous nature of the
Interior of the lid as modified.
3. That by this invention the lid can either be made of enamelled earthenware
in its entirety, or the inner covering as a., and b., made of the same or similar non-
njurious material, when all metallic influences are equally excluded.
