PROVISIONAL SPECIFICATION.
Improvements in Attaching Handles to Teapots and other like
Vessels.
1, JOHN EDWARD BINGHAM of Howard Street, Sheffield, in the County of
York, Manufacturer, do hereby declare the nature of my invention to be as
follows:-
The object of my invention is to attach the handles of teapots and other vessels used
to contain hot liquids, in such a manner as to leave a very small amount of metal
at the junction of the two parts, so that the least possible amount of heat may be
transmitted from the pot to the handle.
I propose therefore to use hollow metallic handles, and preferably such as are
described in the Specification of Patent No. 324578 and to cut away portions of the
metal, in the form of serrations or the like, from the edge at the top and bottom
portion of the handle which is to form the junction, or point of contact with the
body of the pot or vessel.
The serrations or indentations may be of any desired form and number, and the
points, or intermediate pieces of metal will form the points of attachment, and will
be soldered to the side of the vessel.
By this method of attaching handles I reduce the area of metal at the junction
without materially interfering with the strength or durability of the handle, and
thus prevent the rapid communication of the heat from the body of the vessel to
the handle, and to aid in keeping the handle cool through the increased admission
of air.
I may carry out the same principle, by applying the serrations at a short distance
from the junction of the two parts.

COMPLETE SPECIFICATION.
Improvements in Attaching Handles to Teapots and other like
Vessels.
I, JOHN EDWARD BINGHAM of Howard Street, Sheffield, in the County of
York, Manufacturer, 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 object of this invention is to attach the handles of teapots, coffee pots, and
other like metallic vessels used to contain hot liquids, in such a manner as to leave
a very small amount of metal at or near the junction of the two parts, so that the
least possible amount of heat may be transmitted from the body of the pot to the
handle.
And in order that the present invention may be clearly defined and understood,
I have annexed a sheet of drawings illustrating three different ways, or modifications
of the same way of attaining the desired result, similar letters indicate similar parts
in any of the figures.
Fig. 1, represents a coffeepot handle.
Fig. 2, represents a teapot handle.

page_text: as are described in the Specification of my former Patent No. 3245 of 1878, and I
cut away portions of the metal in the form of serrations or other forms of indenta-
tion, or incision, in the edges of the top and bottom sockets or parts which form the
junction of the handle and the body of the pot.
These serrations, indentations or incisions may be of any desired form and
number, and may be used in conjunction with the holes or perforations described in
my former Patent, and the points or intermediate pieces of the edge between the
serrations, will form the points of attachment by which the handle will be secured
by soldering to the body of the vessel.
Thus in Fig. 1, the serrations are marked S, the perforations are marked P,
and the points or edges of attachment are marked E.
In this figure, the handle being intended for a coffeepot and therefore required
to carry a considerable weight, the points of attachment E, are large, while in the
arrangement or formation shown in Fig. 2, the points of attachment E, are smaller,
and the serrations S, more numerous, but the form of the serration in any case may
be varied, to suit the construction of handle, as shown in Fig. 3.
By this method of attaching handles to vessels, I reduce the area (or amount) of
metal at the junction of the handle and body, without materially interfering with
the strength or durability of the handle, and I thus prevent the usual rapid com-
munication or transmission of the heat from the body of the vessel to the handle,
and keep the handle cool by reason of the reduced area of connecting metal, and the
increased admission of air through the serrations or indentations, by the expansion
of heated air, and the consequent influx of cooler air into and through the hollow
or tubular handle.
Having now particularly described and ascertained the nature of my said inven-
tion, and also the manner in which it may be carried into practice, I declare that
what I claim is :-
In attaching the handles of teapots, coffeepots, and other like vessels intended to
contain hot liquids, and as a means of preventing the transmission of heat from the
body to the handle; preparing the edges of the upper and lower sockets, or of the
handle itself (as the case may be), at the point of contact or junction with the body,
with serrations, or other equivalent openings, for the purpose of reducing the metal
at that part, and to provide entrances for the passage of air into and through the
hollow handle, substantially as hereinbefore described and shown in the drawings.
Dated the 27th day of August 1891.
