IMPROVEMENTS IN HANDLES FOR TEAPOTS AND COFFEE POTS AND OTHER SIMILAR VESSELS."
Year: 1880

page_text: LETTERS PATENT to Joseph Ridge, of Sheffield, in the County of York,
Manufacturer, for an Invention of "IMPROVEMENTS IN HANDLES FOR TEAPOTS
AND COFFEE POTS AND OTHER SIMILAR VESSELS."
PROVISIONAL SPECIFICATION left by the said Joseph Ridge at the Office
of the Commissioners of Patents on the 17th July 1880.
"IMPROVE-
JOSEPH RIDGE, of Sheffield, in the County of York, Manufacturer.
MENTS IN HANDLES FOR TEAPOTS AND COFFEE POTS AND OTHER SIMILAR VESSELS."
My Invention relates to the handles of teapots, coffee pots, and other similar
vessels for containing hot liquids, and more particularly to the method of attaching
the same to the bodies of the said vessels so as to prevent the handles from becoming
hot when the vessels are filled with hot liquids.
In order to effect this object I make the sockets to which the handles are usually
attached separate from the body of the vessel, and having the interior hollow and
tapering to the end to which the handle is attached. The handle is made with the
ends set down so as to form a shoulder or collar, the smaller part being by
preference screwed and fitted with a nut. The screwed portion is of smaller
diameter than the hole in the socket through which it passes, but a tapered
or coned ferrule of some nonconducting material, such as wood, horn, or bone, is
arranged to fit over the screw and fill up the annular space between the screw and
the socket and to take a bearing against a ring or washer of similar nonconducting
material which fits against the shoulder before mentioned, thus completely isolating
the metal of the handle from the metal of the vessel.
The parts are then secured together by the nuts, which may be further secured
by being soldered to the screws so as to effectually prevent any liability of them
coming loose. The sockets with the handle attached are then soldered to the side
of the vessel in the usual manner. If desirable, instead of the screw and nut to
attach the handle to the sockets I use a washer and rivet the end of the handle
over it.

the said Joseph Ridge in the Great Seal Patent Office on the 14th January
1881.
JOSEPH RIDGE, of Sheffield, in the County of York, Manufacturer. "IMPROVE-
MENTS IN HANDLES FOR TEAPOTS AND COFFEE POTS AND OTHER SIMILAR VESSELS."
My Invention relates to improvements in the method of attaching the handles
to teapots, coffee pots, and other similar vessels for containing hot liquids, in such
a manner as to prevent the said handles becoming uncomfortably hot when the
vessels are charged with hot liquid, and in order to effect this object in the
manufacture of a teapot, for example, I attach the handle in the first place to short
sockets in the following manner :-The sockets are similar in their configuration to
_those at present in use, and are made hollow and by preference tapering to the end
to which the handle is attached. A tapered plug or cone of nonconducting material
(such as horn) fits the interior of the socket and projects a short distance through
the smaller end for the purpose of receiving a washer of nonconducting material
(such as ivory). The plug or cone is provided with a central hole to receive a
screw of corresponding size which projects from the handle, and which when passed
through the hole in the plug or cone is secured by means of a nut screwed on from
the inside of the socket. The socket is then soldered to the body of the teapot.
And in order that my Invention may be more fully understood I will now
proceed to more particularly 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 all the Figures.
-
Fig. 1 is a side and front view of the socket.
Fig. 2 are views of the tapered plug or cone of nonconducting material;. A is_a
side view;
B is a section of same; C is the smaller end with the central hole
through which the screw on the handle passes.
Fig. 3 represents a portion of the handle with the screw D and the nut E.
Fig. 4 is an enlarged representation of the various parts when put together, part
being shown in section and indicated as such in the usual manner by diagonal
lines; F is the socket; B is the plug or cone of nonconducting material through
the centre of which passes the screw D secured by the nut E; G is the
nonconducting washer held between the end of the socket F and the shoulder of
the handle H.
Fig. 5 is an enlarged view of a modification of my Invention, in which the
conical plug of nonconducting material is arranged in the handlo instead of the
socket, the remaining parts being slightly altered to suit the different position of
the cone or plug. In this arrangement the nut E may be dispensed with, and the
screw may be screwed into a threaded hole formed in the end of the socket.
It will be seen that by this arrangement complete isolation of the metal portion
of the handle from the metallic body of the vessel and the socket is effected by the
peculiar arrangement of the nonconductors.
Fig. 6 represents the finished handle as attached to the side of the vessel.
Having now described and particularly ascertained the nature of my said
Invention, 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 thereforo claim as the Invention secured to me by the hereinbofore in part
recited Letters Patent is,-
First. The use of a conical plug of nonconducting material placed in the socket
or that part of vessels for containing hot liquids to which the handle is attached,
substantially as described and illustrated.

page_text: Second. The peculiar method of attaching the handles of teapots, coffee pots,
and other similar vessels for containing hot liquids, to the bodies of such vessels,
for the purpose of preventing the said handles from becoming uncomfortably hot,
substantially as described and illustratod, or any mere modification thoreof.
In witness whoreof, I, the said Joseph Ridge, have hereunto set my hand
and seal, this Sixth day of January, in the year of our Lord 1881.
