An Improvement or Improvements in Connecting the Metallic
Handles of Metallic Tea Pots and Coffee Pots and of other Vessels
for Holding Hot Liquids to the said Pots and Vessels.
I HENRY THOMAS FELLOWS of Shirley Road Acock's Green in the County of
Worcester Manager of Works do hereby declare the nature of this Invention to
be as follows:-
My invention is applicable principally to metallic tea pots and coffee pots and
has for its object to prevent the transmission of heat from the pot to the handle
and to connect the handles to the vessels more securely than is effected by the
ordinary methods of connection.
I will describe my invention in connection with a tea pot. At each of the two
points of the body of the tea pot at which the handle is to be connected with the
body I fix by soldering or otherwise a short screwed pin or wire the said screwed
pins being fixed perpendicularly or nearly so to the parts of the pot where they are
fixed. I place upon each screwed pin a slightly conical piece of ivory or ebony
or other imperfect conductor of heat which I will call the insulator. The said
insulator has an axial hole through which the said screwed pin passes and has a
flange or expansion at its base. The said screwed pins are of a length somewhat
greater than the diameter of the portions of the handle at the parts where it is
connected to the body. Each of the said parts of the handle has a hole made
in it the size of the hole at that side of the handle turned towards the body of
the pot being suitable for the reception of the insulator while the holo at the
opposite side of the handle is only sufficiently large to pormit to the passage of the
screwed pin which is sufficiently long to project a short distance through the said
hole. The handle being placed in position abuts upon the flanges or bases of the
insulators while the screwed ends of the pins carrying the insulators project
through the smaller holes described. Screw nuts which may be externally orna-
mented are screwed home on the projecting ends of the screwed pins and the
handle is thereby securely fastened to the body of the tea-pot.
The screw nuts may be soldered to the handle after having been screwed home
and their accidental removal thereby prevented.
Handles attached according to my invention are not liable to become loose as
andles are which are attached in the ordinary way by pins.
The application of my invention to metallic vessels other than tea pots and
coffee pots differs in no essential respect from its application to a tea pot as
erein before described.

1 HENRY THOMAS FELLOWS of Shirley Road, Acock's Green in the County of
Worcester Manager of Works do hereby declare the naturo of my Invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:—
My invention is applicable principally to metallic tea pots and coffee pots and has
Pin Q21

page_text: for its object to prevent the transmission of heat from the pot to the handle and to
connect the handles to the vessels more securely than is effected by the ordinary
methods of connection.
I will describe-my-invention in connection with a tea pot.
At each of the two points of the body of the tea pot at which-the handle is to be
connected with the body I fix by soldering or otherwise a short screwed pin or wire
the said screwed pins being fixed perpendicularly or nearly so to the parts of the pot
where they are fixed. I place upon each screwed pin a slightly conical piece of ivory
or ebony or other imperfect conductor of heat which I will call the insulator. The
said insulator has an axial hole through which the said screwed pin passes and has a
flange or expansion at its base. The said screwed pins are of a length somewhat
greater than the diameter of the portions of the handle at the parts where it is con-
nected to the body. Each of the said parts of the handle has a hole made in it the
size of the hole at that side of the handle turned towards the body of the pot being
suitable for the reception of the insulator while the hole at the opposite side of the
handle is only sufficiently large to permit of the passage of the screwed pin which is
sufficiently long to project a short distance through the said hole. The handle being
placed in position abuts upon the flanges or bases of the insulators while the screwed
ends of the pins carrying the insulators project through the smaller holes described.
Screw nuts which may be externally ornamented are screwed home on the projecting
ends of the screwed pins and the handle is thereby securely fastened to the body of
the tea pot.
The screw nuts may be soldered to the handle after having been screwed home and
their accidental removal theroby prevented.
I will now proceed to describe with reference to the accompanying Drawing the
manner in which my invention is to be performed.
Figure 1 represents in elevation and Figure 2 partly in elevation and partly in
section a metallic tea pot the metallic handle of which is connected to the body of the
pot according to my invention; Figure 3 represents the insulator and the tubular
metallic lining for the holes in the upper part of the handle and Figure 4 represents
the two parts shown in Figure 3 combined together; Figure 5 represents the insulator
and the tubular metallic lining for the holes in the lower part of the handle and
Figure 6 represents the two parts shown in Figuro 5 combined together.
The same letters of reference indicate the same parts in the several Figures of
the Drawing.
a is the body of the metallic tea pot and b is the metallic handle of the same having
holes at i, i where it is to be attached to the body a; ce are the two short screwed
pins or wires fixed perpendicularly on the body a by soldering their conical heads
or inner ends to the exterior of the said body but I do not limit myself to any
particular way of securing the said screwed pins or wires to the outside of the
body of the pot; d is the insulator for the upper part of the handle band e is
the insulator for the lower part of the said handle.
The insulators d and e are made of ivory ebony or other imperfect conductor
of heat and are preferably of different sizes as represented and are fitted upon the
inner ends of the screwed pins or wires c c, the countersunk conical parts of the
said insulators seating themselves upon the conical heads of the said screwed pins.
It will be seen by an examination of the Drawing that each insulator d and e
has an axial hole through which the screwed pin passes and has a flange or
expansion at its base which bears against the metallic body of the teapot. The
front parts of the insulators d, e are conical and upon the conical parts the conical
metallic linings f, g (shown separately in Figures 3 and 5) respectively fit. The
said metallic linings 9 are placed in the holes ii in the parts of the handle b
which are to be connected to the body of the tea pot. It will be seen by an
examination of Figure 2 that the size of the holes i, i at that side of the handle
turned towards the body of the pot is suitable for the reception of the wide parts
of the linings fg in which the conical parts of the insulators fit while the holes i i

page_text: at the opposite side of the handle are only sufficiently large to receive the con-
tracted cylindrical ends of the said metallic linings. Although I prefer to use the
metallic linings fg fitted into the holes i, i in the handle for receiving the conical
parts of the insulators d, e yet the said metallic linings may be omitted and the
insulators be fitted directly into the larger holes in the side of the handle.
k, kare the screw nuts which are screwed upon the outer projecting ends of the
screwed pins or wires c, c for securing the several parts of the connecting pieces in
their places.
The parts for effecting the insulation of the metallic handle from and its connection
to the body of the teapot are fitted and fastened together in the following manner.
The non-metallic insulators d, e are first fitted upon the bases of the fixed screwed
pins c c on the body of the pot. The metallic handle b, in the holes at ii in which
handle the tubular liningsfy have been fitted, is next placed in position upon the
insulators d, e the linings in the handle abutting against the flanges or bases of the
insulators while the screwed ends of the pins cc project beyond the smaller holes in
the said handle. The screw nuts k, k are now screwed home upon the projecting ends
of the screwed pins cc so as to bear against the outer side of the handle and the
handle is thereby securely fastened to the body of the pot.
The accidental removal of the screw nuts k, k may be prevented by soldering them
to the handle after they have been driven home.
By an examination of Figure 2 it will be seen that by the use of the non-motallic
insulators d, e the continuity between the metal of the body a of the pot and the
metallic handle is broken and the transmission of heat between the said parts is
thereby more or less prevented.
Metallic handles attached according to my Invention are not liable to become loose
as handles which are attached in the ordinary way by pins.
The application of my invention to metallic vessels other than tea pots and coffee
pots differs in no essential respect from its application to a tea pot as hereinbefore
described and illustrated in the accompanying Drawing.
Having now particularly described and ascertained the nature of my Inven-
tion and the manner in which the same is to be performed I declare that I claim
as my invention :-
Connecting metallic handles to metallic tea pots and coffee pots and other vessels
for holding hot liquids and more or less preventing the transmission of heat from
the pot or vessel to the handle substantially in the manner herein before described
and illustrated in the accompanying Drawing; that is to say, attaching to the
body of the pot or vessel short screwed pins or wires cc and combining with the
said screwed pins or wires the ivory or non-metallic insulators de, and preferably
the metallic linings f g fitted into holes in the metallic handle, the several con-
necting parts being secured together by means of screw nuts screwed upon the
projecting ends of the screwed pins or wires substantially as described and illustrated.
