PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Rings Used in Frames for
Spinning and Doubling Textile Fibres.
I ROSE ANN JOHNSON of No. 48 Meadow Street Moss Side Manchester in the
County of Lancaster of no occupation do hereby declare the nature of this Invention
to be as follows:-
My invention relates to improvements in the manufacture of rings used in frames
for spinning and doubling textile fibres and the chief object of my improvements is
to produce rings of earthenware which rings will be as efficient and almost as durable
as metal rings and at the same time will cost very much less in production.
Various attempts prior to my present invention have been made to manufacture
rings of materials other than metal such as glass porcelain &c., but such attempts
have from various causes hitherto proved unsuccesful owing to certain fatal defects.
For example rings intended to serve the required purpose have been made of porcelain
but the use of porcelain and other highly vitreous bodies or substances is open to this
fatal objection namely that when a porcelain ring is fired it is difficult if not impossible
to maintain the true annular form.
I have discovered however that an earthenware body of sufficient hardness and
possessing the other requisite qualities can be obtained by certain admixtures of
china clay and ball clay with flint and cornish stone. The clay or earthenware
body thus composed can be turned and formed into the required shapes and sizes
and will retain those shapes when under the necessary fire thus producing rings
of the required hardness and accuracy. Further by the composition of a suitable
glaze and by employing a convenient device for holding the rings in suspension
while exposed to fire in order to fuze the glaze tlie necessary smooth surface is
obtained and rings successfully manufactured which are novel cheap and can be used
with less friction and as great if not greater advantage than those produced from
metal and other materials.

Improvements in the Manufacture of Rings Used in Frames for
Spinning and Doubling Textile Fibres.
I, ROSE ANN JOHNSON, of No. 48 Meadow Street, Moss Side, Manchester, in the
County of Lancaster, of no occupation, 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:-

I have discovered however that an earthenware body of sufficient hardness and
possessing the other requisite qualities can be obtained by certain admixtures of china
clay and ball clay with flint and Cornish, stone these ingredients being used in such
proportions as to produce what is known technically in the trade as a china body."
The clay or earthenware body thus composed can be turned and formed into the
required shapes and sizes and will retain those shapes when under the necessary fire
thus producing rings of the required hardness and accuracy. Further by the com-
position of a suitable glaze and by employing a convenient device for holding the
rings in suspension while exposed to fire in order to fuse the glaze the necessary
smooth surface is obtained and rings successfully manufactured which are novel cheap
and can be used with less friction and as great if not greater advantage than those
produced from metal and other materials.
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 :-
The improved earthenware rings for use in spinning and doubling frames said rings
being manufactured from admixtures of china clay and ball clay with flint and
Cornish stone and then glazed and fired substantially as and for the purposes
described.
