We WILLIAM ATKINSON, and EDWIN TATTERSALL, of Oswald Street Works,
Thornton Road, Bradford, in the County of York, Enamellers, do hereby declare the
nature of this invention for IMPROVEMENTS IN SPINNING AND TWISTING MACHINERY
to be as follows:-
This invention relates to novel and useful improvements in throstle, mule,
and other classes of spinning or twisting machinery; and its object is to prevent the
yarn by its constant friction, over the various guides and other metallic portions of
such machines with which it comes in contact, from so nicking or cutting the said
portions that knots or other protuberances cannot pass and the yarn is broken.
For this purpose those parts of the metallic portions in mule, cap, ring, flyer and
other classes of spinning or twisting machinery coming in contact with or exposed to
the frictional action of the yarn such as the various guides, caps, flyers, faller wires,
and all other parts so exposed are covered with a durable enamel capable of withstanding
the constant friction occasioned by the passage of the yarn.
The said enamelled parts are commonly made of steel, hardened or otherwise; by
enamelling them as above described iron may be advantageously used for their
construction.

We, WILLIAM ATKINSON, and EDWIN TATTERSALL, of Oswald Street Works,
Thornton Road, Bradford, in the County of York, Enamellers, 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:-
This invention relates to novel and useful improvements in throstle, mule and other
classes of spinning or twisting machinery, and its object is to prevent the yarn by its
constant friction over the various guides and other metallic portions of such machines
with which it comes in contact from so nicking or cutting the said portions that knots
or other protuberances cannot pass and the yarn is therefore broken.
For this purpose those parts of the metallic portions in mule, cap, ring, and other
classes of spinning machinery coming in contact with or exposed to the frictional
action of the yarn are covered with a durable enamel capable of withstanding the
constant friction occasioned by the passage of the yarn.
The parts we find it most advantageous to enamel are, the various guides as for
instance the eyes when formed of metal in the guide boards of cap ring, and flyer
frames and the twizzles and similar guides, the eyes at the ends of the flyer arms, the
lower edges of the caps used in cap frames, the faller wires of mule spinning machinery,
and other similar parts.
We preferably make the parts to be enamelled of cast or wrought iron and the
enamel is applied thereto in the ordinary way. The following enamelling composition
and process (commonly known as Paris's process) gives satisfactory results, but any
hard vitreous enamel having a smooth surface after fusion may be used.
The objects to be enamelled are first cleaned with dilute sulphuric acid then a coat
of powdered composition formed of 130 parts of broken glass, 20 parts of carbonate
of sodium, and 12 parts boracic acid, is spread over the parts to be enamelled, such
parts having been previously covered with a suitable adhesive liquid such as gum to
make the enamel powder adhere. The objects are now dried and then heated in the
enamelling furnace until the powder fuses and flows evenly over the surface.
Having now particularly described and ascertained the nature of our said Invention,
and in what manner the same is to be performed, we declare what we claim is:
In a spinning or twisting machine, the combination with the metallic parts exposed
to the frictional action of the yarn, of a covering of enamel, substantially as herein
described and for the purpose specified.
Dated this 29th day of August 1887.
