TEA-POTS, AND COFFEE-POTS, AND OTHER SIMILAR ARTICLES."

PROVISIONAL SPECIFICATION left by the said John Edward Bingham at the
Office of the Commissioners of Patents on the 16th August 1878.
JOHN EDWARD BINGHAM, of Sheffield, in the County of York, Manufacturer.
IMPROVEMENTS IN HANDLES FOR TEA-POTS, AND COFFEE-POTS, AND OTHER SIMILAR
ARTICLES."
My Invention relates to the handles of tea-pots, coffee-pots, and other similar
vessels for containing hot liquids, and has for its object preventing such handles
from becoming unduly heated when the vessels are charged with hot liquid.
In order to effect this object I cast, stamp, or otherwise form the handle of such
vessels hollow, or with a passage in the interior extending from one end of the
handle, or thereabouts, to the opposite end thereof, and near the opposite extremities
of this passage I make perforations through the material of which the handle is
composed, so that a communication is established between the interior of the
handle and the external atmosphere for the purpose of admitting and inducing a
circulation of air through the handle. The handle is thus maintained in a com-
paratively cool condition when the vessel is charged with hot liquid, without the
intervention or use of any non-conducting material now generally employed.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Edward Bingham in the Great Seal Patent Office on the
15th February 1879.

My said Invention relates to the construction of handles for tea-pots, and coffee-

page_text: pots, and other similar vessels for containing hot liquids, and has for its object pre-
venting such handles from becoming unduly heated when the vessels are charged
with hot liquid.
In order to effect this object I form the handle hollow, by preference throughout
its entire length, or with a passage in the interior extending from one end to the
opposite end, or nearly so, and near the opposite extremities of this passage I make
perforations through the material of which the handle is composed, so that a com-
munication is established between the interior of the handle and the external
atmosphere for the purpose of admitting and inducing a circulation of air through
the handle, and also for the purpose of cutting off the heat by reducing the bulk
of the metal, which acts as a conductor of heat from the side of the vessel to the
handle. The handle is thus maintained in a comparatively cool condition, so that
the pot or other similar vessel may be manipulated without inconvenience to the
holder.
And in order that my said Invention may be fully understood, I shall now
proceed more particularly to describe the same, and for that purpose shall refer
to the several Figures on the annexed Sheet of Drawings, the same letters of
reference indicating corresponding parts in both the Figures.
Figure 1 of the accompanying Drawings represents a side elevation of a handle
constructed according to my said Invention, and Figure 2 is a vertical section of the
same corresponding to Figure 1.
The handle is made hollow or with an internal passage A from its extremity B
to its extremity B', at which points it is to be attached to the vessel to which it is
intended to be applied, and perforations are formed at C, C', through the sides of
the handle, by means of which air from the surrounding atmosphere is admitted
into the internal passage A. A circulation of cool air is thus induced and main-
tained in and through the handle in the direction indicated by the arrows,
whereby the handle is preserved at an equable temperature, the perforations C, C¹,
further contributing to this result by reducing the bulk of material at the parts
where they are situate, which acts as a conductor of heat from the vessel to the
handle.
It is obvious that the shape and arrangement of the perforations C, C¹, may be
varied, as the perforations may be so arranged as to contribute to the ornamentation
of the handle, and be otherwise modified acccording to circumstances.
Having now described and particularly ascertained the nature of my said In-
vention, and the manner in which the same is or may be used or carried into effect,
I would observe in conclusion that what I consider to be novel and original, and
therefore claim as the Invention secured to me by the herein-before in part recited
Letters Patent is, the combination, in handles for tea-pots, coffee-pots, and other
similar articles, of a permanent internal passage, and of perforations through the
sides of the handle near the opposite extremities communicating with the said
internal passage, substantially as and for the purposes herein-before described.
In witness whereof, I, the said John Edward Bingham, have to this my
Specification set my hand and seal, this Twelfth day of February, One
thousand eight hundred and seventy-nine.
JOHN EDWARD BINGHAM. (L.S.)
