PROVISIONAL SPECIFICATION.
Improvements in Tea and Coffee Urns.
I, THOMAS CLARKE, of Holly Lodge, Handsworth, near Sheffield, in the County
of York, Gentleman, do hereby declare the nature of this invention to be as
follows:-
This invention relates to tea and coffee urns, and has for its object to arrange
means whereby the exact quantity of water required for infusion or mash of tea can
be seen whilst pouring the boiling water into the urn, and the quantity of liquid in
the urn may be indicated upon the completion of the infusion or mash, as well as
subsequent to the distribution of any portion of said contents; to attain which I fix
or fit to the tea or coffee urn a glass or transparent tube, which communicates by
means of a suitable metal branch or fitting with the lower part of the internal
portion of urn, and this branch also communicates directly with the ordinary tap
for drawing off the contents. The said transparent tube is preferably arranged in
a vertical position upon the outer side of the urn, and it is fitted to a frame or case
the sides of which are marked with indications of measures such as pints or half
pints, or other indications of the contents of the urn, and the upper end of said tube
communicates with the upper part of the interior of the said urn.
By this means it will be obvious that the amount of water poured into the urn
can be ascertained at a glance, thereby enabling the exact quantity of water to be
used for the proper infusion of the amount of tea leaf employed, and the amount
remaining subsequent to the withdrawal of any quantity of tea from the urn can be
seen, so that it is possible with my improvements to regulate the quantity of water
and tea in such a manner as to ensure the beverage to be of uniform strength.
Dated this 11th day of October 1893.

COMPLETE SPECIFICATION.
Improvements in Tea and Coffee Urns.
I, THOMAS CLARKE of Handsworth near Sheffield, Yorkshire, Gentleman, 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 drawings herewith on one sheet numbered 19170, 12 Octr. '93, shews the
elevation and section of this urn. The elevation shews the body only, without its
loose stand on which it will rest, or its handles for carrying it, or its lid.
A B is a glass tube encased in a metallic tube or sheath to protect it from
fracture. It is fixed inside, but visible outside through a slit, or aperture in the side
of the urn.
The figures 1 to 8 marked alongside the tube indicate the number of half-pints
of liquid in the urn. Below the bottom of the tube, the part next to figure 1.
shews the tap for drawing off the liquid. The section shews the tube T as fixed
inside.

page_text: 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 :-
The fixing inside of tea or coffee urns or pots, a glass tube (visible outside
through an aperture in the side of the urn) into which the liquid rises and shews
the depth of the contents of the urn in like manner as water gauges do those of a
steam boiler, but the measures of the contents are indicated by figures engraved on
the outside of the urn, alongside of the glass tube.
Dated October 6th 1894.
