Improvements in Sockets or Attachments to Handles for Vessels to
Contain Hot Liquids, and for Better Preventing the Transmission
of Heat to the said Handles.
I, FREDERICK HALL of No. 43 Suffolk Road, Sheffield, in the County of York,
Britannia Metal, Silver and Electro-Silver Plate 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 :-
My invention relates more especially to the manufacture of Tea or Coffee Pots, and
is applicable to all kinds of vessels to contain hot liquids. Its object is to secure the
complete severance of all metallic contact between the body of such vessels and their
handiles, so that the heat may not be transmitted into the said handles.
The process of carrying out my invention will require to be slightly varied to suit
different metals or vessels as will be readily understood. But in the manufacture of
a Pot in Britannia or other mixture of metal which admits of the parts being joined
together by soft older, I prefer to proceed as follows-1 provide a suitable mould,
shaped to produce a socket to attach to the body of the pot and also of a separate
portion for fastening to the handle: Across this mould is first placed a piece of Wood,
Ivory, Bone other tough non-conducting material, and then fill up the mould with
molten metal. The castings so produced after the usual trimming and finishing are
ready for soldering to the pot and to the handle, and form without pin, rivet or screw,
strong, firm & durable connections without the slightest metalllc contact between
the pot & the handle.
When carrying out my invention in connection with the manufacture of a vessel
in Silver, Nickel or any of the metals or alloys which require to be brazed or hard
soldered, and which do not admit of the necessary parts being cast in moulds, I
vary the process as follows; I make up a socket to receive the handle, and after it
has been joined to the pot, I introduce the handle, into which has been fitted in a
transverse direction a piece of wood, Ivory or other non-conducting substance, with
or without washers or ornamental projections: and then connect or fasten all the
parts together by means of a screw, pin or rivet which passes entirely through the
non-conducting centre without touching or making contact with the handle at any
point, and thus render the transmission of heat by conduction impossible.
The said sockets, attachments and handles may be made of any shape or materials
to suit the design of the vessel or the use to which it may be put without in any way
departing from the principle or spirit of my invention, and in order that it be
may
properly understood, I now proceed to explain the accompanying Sheet of Drawings
which illustrate each of the processes before described.
Fig. 1. is a view partly in section on line a. b of fig. 2.
Fig. 2. a side elevation of completed article for soft metals.
Fig. 3. is a view partly in section on line a₂ b of fig. 4.
Fig. 4. a side elevation of completed article for hard metals.
The like letters refer to like parts in all the Figures.
A. is the socket to be joined to the pot or etc.
B. is the connection to handle. C. is the transverse piece of wood or cone of non-
conducting material.
D. the handle. E. a portion of the body of a pot or etc.
F. is a screw passing through C and securing all together by means of nuts G. G.
while H. H. show two ornamental washers of ivory fitted upon C and filling the
spaces otherwise left between the socket A and the handle piece B & which in
Fig. 1 are represented by the heavy black lines. From which it will be seen that
this combination of parts effectually prevents the conduction of heat from the
LL D

page_text: Having now described and ascertained the nature of my Invention and shown
how the same is to be performed, I declare that what I claim is.
1st. The formation of sockets and attachments cast in moulds in connexion with a
transverse non-conducting centre piece or pin, completely isolating the handle and
preventing the transmission of heat thereto.
2nd. The formation of sockets, attachments and handles in separate parts &
connected together by means of a transverse centre piece of non-conducting material,
substantially as described and for the purposes set forth.
