PROVISIONAL SPECIFICATION.
Improvements in Moulding Pottery and in Apparatus therefor.
I, WILTON PARKER RIX, of 34, Liverpool Road, Newcastle, in the County of
Stafford, Decorative Potter, do hereby declare the nature of this invention to be
as follows:-
This invention relates more especially to moulding cylindrical jars but is also
applicable for other purposes.
Cylindrical jars are now usually made in revolving plaster moulds by means
of a tool which forms the inside of the jar. In this process the clay adheres to
the mould and the jar cannot be removed until it has more or less dried which
involves loss of time and the use of a large number of moulds-the moulds also
quickly wear out.
According to this invention the mould is formed of perforated metal lined with
non-absorbent paper or like material. The mould is preferably covered outside
with one or more layers of wire gauze which gives the necessary strength whilst
allowing of the escape of air. At the top of the mould a loose spring ring is in-
serted having a ridge or flange upon it which forms the usual groove at the top
of the jar. Above this ring is an annular lid which serves to form the top of the
jar and prevents the escape of clay. A loose bottom is provided and on the lid
being opened this bottom is forced up through the mould expelling the jar with
the paper and ring.
Designs may be produced on the jar by watermark or other patterns on the
paper or it might be on the perforated metal. Or designs may be printed on the
paper and so transferred to the clay.
In the case of pottery of other forms than cylindrical the mould and the paper
or other lining are suitably shaped.

the mould and the jar cannot be removed until it has more or less dried which
involves loss of time and the use of a large number of moulds-the moulds also
quickly wear out.
According to this invention the mould is formed of perforated metal or other
permeable material such as textile fabric or the like lined with paper or like
material, The mould is preferably covered outside with one or more layers of wire
gauze which gives the necessary strength whilst allowing of the escape of air.
At the top of the mould a loose spring ring is inserted having a ridge or flange
upon it which forms the usual groove at the top of the jar. Above this ring is
an annular lid which serves to form the top of the jar and prevents the escape
of clay. A loose bottom is provided and on the lid being opened this bottom is
forced up through the mould expelling the jar with the paper and ring.
Designs may be produced on the jar by watermark or other patterns on the
paper or it might be on the perforated metal. Or designs may be printed on the
paper and so transferred to the clay.
In the case of pottery of other forms than cylindrical the mould and the paper
or other lining are suitably shaped.
The drawing shows a half side elevation and half vertical section of a mould
constructed according to this invention.
a is a metal cup such as is now employed screwed onto a revolving spindle
and lined with plaster c in the ordinary way. d is wire gauze and e is perforated
metal fixed to the flange or ring el. f is non-absorbent paper or like material
and g a loose spring ring. h is an annular lid, j is the jar which has been moulded,
k is the bottom of the mould and is the moulding tool.
When the moulding is complete the lining d is lifted from the cup a and the
bottom k is forced up by a rod introduced through the hole so expelling the jar j
with the paper f and ring g and the latter is then sprung off.
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:-
1. Moulding pottery in a permeable mould lined with paper or like material
substantially as described.
2. The use of a spring ring for forming the groove at the top of the jar sub-
stantially as described.
3. The use of an annular lid at the top of the mould to prevent the escape of
clay substantially as described.
4. Moulds with or without the wire gauze substantially as described and illus-
trated in the drawing.
