PROVISIONAL SPECIFICATION.
Improvements in and relating to Tea and Coffee Pots.
I FRANK WILLIAM BLAYDES, of 33 Virginia Street, Glasgow, Lanarkshire,
Agent, do hereby declare the nature of my invention to be as follows:-
The object and advantages of my invention are the production of tea and coffee
pots made of metal such as Britannia metal, nickel, copper, brass, or such like with
interior linings of hard rigid metal such as steel, iron or tin-plate with enamelled
surfaces so that the tea and coffee or other contents are prevented acting on the
surface of the outer metal to discolour same or to impart any disagreeable flavour
to the said contents also to render the interior of such utensils capable of being
readily cleaned, and at same time to impart strength.
By my improvements I first make the interior linings or vessels of the desired
form which the interior of the tea or coffee pot is to assume of sheet steel, iron,
tinplate, or other suitable rigid metal preferably dished or punched up in a seamless
manner or for certain shapes they may have seams or be jointed together, and then
enamel the interior surface of such lining vessels by any of the known processes
which will produce a hard smooth and durable surface. By this process a lining
can be produced of any strength and free from the danger of fracture which
pertains to all porcelain or earthenware linings such as are at present in use. These
linings would after preparation in the aforesaid manner be covered with an outer
coating or covering of metal such as Britannia metal, nickel, copper, brass, or such
like, spun on to or otherwise laid over the outside, and afterwards electro plated or
otherwise ornamented. Perforations would be formed in the inner lining for the
passage of the contents to the spout formed on or affixed to the outer covering.
As the inner lining could be made of any desired strength the outer casing of
metal could be reduced to a minimum of thickness and thus a great saving would
be effected.

COMPLETE SPECIFICATION.
Improvements in and relating to Tea and Coffee Pots.
I, FRANK WILLIAM BLAYDES, of 33 Virginia Street, Glasgow, Lanarkshire,
Agent, do hereby declare the nature 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 in writing reference being had to the accompanying sheet
of drawings, that is to say :-
The object and advantages of my invention are the production of tea and coffee
pots made of metal such as Britannia metal, nickel, copper, brass, or such like with
interior linings of hard rigid metal such as steel, or iron, with enamelled surfaces
so that the tea and coffee or other contents are prevented from acting on the surface
of the outer metal to discolour same or to impart any disagreeable flavour to the
said contents also to render the interior of such utensils capable of being readily
cleaned, and at same time to impart strength.
And in order that my said invention may be properly understood I have hereunto
appended an explanatory sheet of drawings in which
Figure 1 represents a teapot shown partly in section, and Figure 2 a teapot
spout partly in section, showing an improved manner of attaching the spout to the
body.

page_text: Referring to the drawings :—
By my improvements I first make the interior linings or vessels A, of the desired
form which the interior of the tea or coffee pot is to assume of sheet steel, iron,
or other suitable rigid metal preferably dished or punched up in a seamless manner
or for certain shapes they may have seams or be jointed together and then enamel
the interior surface of such lining vessels A, by any of the known processes which
will produce a hard smooth and durable surface. By this process a lining can be
produced of any strength and free from the danger of fracture which pertains to all
porcelain or earthenware linings, such as are at present in use. These linings A,
would after preparation in the aforesaid manner be covered with an outer coating
or covering B of metal such as Britannia metal, nickel, copper, brass, or such like,
spun on or otherwise laid over the outside, and afterwards electro plated or other-
wise ornamented. Perforations a would be formed in the inner lining for the
passage of the contents to the spout C, formed on or soldered to the outer
covering B, and the usual handle and cover attached. Before affixing the spout C,
to the body B, of the tea or coffee pot a little solder might be run round the edge
of the opening in the body B, as indicated at b to prevent the percolation of the
contents between the lining vessel A, and the body B. By an alternative method
as shown in Figure 2 the spout might have the perforations a, formed in a plate c
across its lower end, and have a small flange c¹ to be turned down as shown all
round after being passed through an opening in both the outer body B and the
lining vessel A, formed of a suitable shape to receive the lower part of the spout.
As the inner lining could be made of any desired strength the outer casing of
metal could be reduced to a minimum of thickness and thus a great saving would
be effected.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
.claim is :-
First. The construction of tea and coffee pots having an inner lining vessel of
enamelled steel, or iron, and an outer covering or body of Britannia metal or other
suntable metal spun on to or otherwise superimposed on the outside of the inner
lining all substantially as herein described and illustrated by the accompanying
drawings.
Second. The construction of tea and coffee pots of Britannia metal, or other
suitable metal, having inner lining vessels of enamelled steel or iron, all substantially
as and for the advantages herein described and illustrated by the accompanying
drawings.
