Improvements in Tea-pots and other Vessels Employed for Preparing
Infusions or for Boiling.
I, WILLIAM BILES 55 Stanley Street Cheetham Manchester, Mathematical
Instrument Maker do hereby declare the nature of this invention to be as
follows:-
The body of the tea-pot or other vessel is formed with a double skin, the space
between the inner and the outer skin being packed with asbestos, slag-wool or other
good non-conductor of heat for the purpose of preventing radiation. The lids of
vessels formed in this manner are preferably fastened by means of headed pins
secured to the under side of the lid which engage with grooves formed in the recess
to which it is fitted.

Improvements in Tea-pots and other Vessels Employed for Preparing
Infusions or for Boiling.
1, WILLIAM BILES 55 Stanley Street Cheetham Manchester, Mathematical
Instrument Maker 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 body of the tea-pot or other vessel is formed with a double skin, the space
between the inner and the outer skin being packed with asbestos, slag wool or
other good non-conductor of heat for the purpose of preventing radiation. The
lids of vessels formed in this manner are preferably fastened by means of headed
pins secured to the underside of the lid which engage with grooves formed in 'the
recess to which it is fitted.
To enable my invention to be more readily understood I will now proceed to
describe the same by means of the drawing in which :-
Fig. 1, is a part vertical section of a tea pot and lid constructed in accordance
with my invention.
'
Fig. 2, is a.plan of the slotted ring in its seat.
Fig. 3, is a section shewing a closed pocket secured to the ring or side walls of
the vessel.
Fig. 4, is a sectional view shewing the locking slots formed in the lid.
Fig. 5, is a vertical section of the upper part of a stoneware infusion vessel.
Fig. 6, is a side view of same shewing bayonet joint formed in side walls.
Fig: 7, is a sectional view of 'infusion pot of stoneware having flat lid.
In the drawing 1, is a tea pot which may bé constructed of white metal, silver,
tin, or other suitable metal. It is formed with a double wall skin or jacket 2, 3,
the space formed by the double walls is filled with asbestos, slag wool sand, or
LD
t

page_text: other good non-conducting material 5, which prevents radiation and consequent
loss of heat. At the top of the tea pot or equivalent vessel having a lid or cover
is a metallic ring 6, having slots 7, formed in the manuer shewn in Fig. 2. To
prevent the non-conducting material from escaping, these slots are enclosed on the
underside by a pocket 10, which may be made by bending up a piece of metal
as shewn in Fig. 3, and soldering sweating or otherwise securely fastening it to
the ring 6, and side walls 2, 3.
For the purpose of filling or packing the space 5, with non-conducting material
holes 11, are formed in the ring which are afterwards plugged up with metal or
other suitable material.
The lid 8, is fitted with one, two, or more rounded or headed pins 9 which are
passed through the rounded or enlarged ends of the slots 7; on slightly twisting
the lid as by the button 4, these pins engage with the narrower part of the slots
and securely fasten it to the tea pot or equivalent vessel thus fitted.
In Fig. 4, I have shewn a variation of my invention in which similar slots 7,
are formed in the lid or cover the headed pins 9, being attached to the ring.
I have also shewn a double ring 6¹ which may in some cases replace the pocket.
In Figs. 5, and 6, I have shewn the arrangement I employ when the tea pot,
infusion, or other vessel is formed in stoneware. The interior flange of the lid or
cover 81, is in one form of my invention fitted with a headed pin or pins 9, which
engages with a slot of rectangular shape 71 formed in the side wall of the recess
to which the lid is fitted.
In Fig. 7, I have shewn in section the way I prefer to fasten the flat shaped
lids employed for covering ordinary stoneware infusion pots, jars, or boiling vessels.
The più 9, is secured by riveting to the lid and passes into a slot hole 7, similar
to that described under Figs. 1, 2, 3. The pocket 10, or the double ring replacing
it, is moulded at the time of making the vessel and attached by fusion or like
means holes 11, are also provided which after the packing process is complete
are packed with cement or the like. It will be seen that by means of my inven-
tion I am enabled to retain the heat necessary for preparing infusions of tea and
other substances in a very simple and most effective manner, and at the same time
the lid is perfectly secured.
I may vary the lid fastening device in a manner depending upon the type of
vessel, for instance the particular device described under Figs. 5, 6, as applied to
articles made in stoneware and the like, may be applied to vessels constructed of
metals or mixtures of them, when their construction will admit.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The combination in or with a tea pot, infusion, or boiling vessel, constructed
of metal or mixtures thereof, china, crockery, stone, or other ware of a double
wall or jacket filled with a non-conducting substance, the ring or rings having
packing holes and plugs or the like and with or without a pocket, the slots in said
ring, and the headed pin or pins secured to the lid or cover engaging therewith,
the respective parts co-operating for effecting the purposes set forth.
2. The combination in or with a teapot, or like infusion or boiling vessel formed
of stone or other ware having a double skin packed with non-conducting material
of the pin or pins 9, fitted to the side of inner flange 8' and engaging with a
bayonet joint slot formed in the recessed outer wall 3, substantially as described
under Figs. 5, 6.
3. In a vessel employed for preparing tea or other infusions or boiling formed
of stone or other ware and having a double skin or jacket the combination of the
pin or pins 9, secured to the lid and engaging with the slots formed in the recess
in which it is fitted as shewn in Fig. 7.
4. For the purpose of conserving the heat in vessels employed for making
infusions, boiling, and like purposes constructed as herein described the combination

packed and retained in position by the means and in the way and manner
described.
