Improvements in Tea or Coffee Urns.
WALTER GRIFFITHS, Highgate Square, Birmingham, Manufacturer, do hereby
declare the nature of this invention to be as follows:-
I provide a body or container similar to an ordinary urn, and in it I price a
second and smaller container which is to receive the tea or coffee-the space
between the inner and outer container being provided for hot water-thus form-
ing a hot water jacket to the inner receptacle which contains the tea or coffee-
the whole having only one radiating or cooling surface.
To this arrangement I provide and attach a special double tap hereinafter
described.
In construction this tap has a double feed pipe, preferably one inside the other,
with a suitable space between them, and so arranged that the inner pipe proceeds
from the inner or tea receptacle, while the outer pipe is attached to and draws
from the outer receptacle.
Both these feed pipes are so conducted to the plug of the tap, that on turning
the said plug its pass-way first corresponds with the way to the inner tube, thus
allowing tea from the inner receptacle to flow. By turning the plug or tap
further, connection is made partly with both the inner and outer pipes and recep-
tacles or containers, thus allowing a mixture of tea and water in any desired pro-
portions to flow-and by turning the tap still further the connection with the
inner or tea receptacle is entirely cut off, and fully connected with the outer pipe
and receptacle, thus allowing water only to flow.
By returning the tap to its original position both receptacles are again cut off.

Improvements in Tea or Coffee Urns.
I, WALTER GRIFFITHS, of Highgate Square, Moseley Road, Birmingham, in
the County of Warwick, Manufacturer, do hereby declare the nature of this inven-
tion. and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
My invention has for its object improvements in tea or coffee urns, by which
the tea or coffee is kept hot through the medium of the hot water which is used
for mixing with the tea or coffee as the case may be thus obviating the necessity
of a hot water jug while by the combination of a tap having a double action the

page_text: tea or coffee can be diluted more or less with water during the filling of the cup
or other article.
In order that my invention may be clearly understood and more easily carried
into practise I have appended hereto a sheet of drawings upon which I have fully
illustrated the nature of my said improvements.
Figure 1 is a vertical sectional elevation through one of my urns suitable for
tea or coffee.
Figure 2 is a plan of same with the lid removed.
Figure 3 is a cross section through bottom of urn and tap.
Figure 4 is a longitudinal section through the tap shewing a modification.
In carrying my invention into effect I provide the receptacle A which contains
the tea coffee or other such liquid and which is surrounded with an outer jacket B
so formed as to contain hot water whereby the contents of the inner receptacle
are kept hot, and hot water for the dilution of the tea or coffee is provided.
For combining the two when the cup or other article is being filled I provide
the tap C which has two ways into it i.e. one a¹ from the inner receptacle A and
one 6 from the outer jacket of hot water B the two being 50 arranged that when
the plug D of the tap is turned partly round until its aperture dis opposite the
way a¹ the tea only passes through, but by turning the plug further round both
tea and water pass through the aperture din relative proportions according to
the position of the mouth of the aperture with regard to the separate outlets
and by further turning the plug D until the aperture is opposite the outlet b¹
only water from the jacket can pass out of the tap C.
I
In the illustration shewn by Figures 1 and 3 the plug D is shewn vertical but
may
have it horizontal as shewn by Figure 4 and I may provide an index on any
part of the tap to shew the position required for the plug to be in when drawing
say either tea or water or an equal mixture of both and from which other pro-
portions could readily be guessed. E is a perforated cap over the mouth of pipe a¹.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is: :―
1st. The improvements in urns for tea and coffee consisting of the double
receptacle one within the other in combination with a single tap connected with
both substantially as and for the purpose herein set forth and illustrated upon
the accompanying drawings.
