I, MARTIN WALSH, of 154, Napier Street, Gorton, Manchester, in the County
of Lancaster, Mechanical Engineer, do hereby declare the nature of this inven-
tion to be as follows:-
This invention is designed to provide a skewer for insertion in cops of cotton
or other yarn to hold or retain it during subsequent operations which will not
fray or disarrange the internal layers of the cop and which can be tightened up
in the interior of the cop after insertion to prevent the nose or end fraying
whilst unwinding.
The skewer will be found applicable for holding cops in winding doubling or
other frames or machines and also in the shuttles of looms.
It consists essentially of a skewer constructed of two pieces of thin channel
steel (or other metal) of a springy nature attached together at one end forming
a point and at the other attached to a tubular socket or sleeve to receive a pin
cr peg the end of which expands the sides of the skewer and causes them to grip
or bind tightly against the interior sides or layers of the cop.
The skewer is made of two pieces of channel steel semicircular or other cross
section attached or connected together at a point at one end by brazing soldering
or otherwise. Instead of steel bronze or other suitable metal may be employed.
At the other end a tubular sleeve or socket is inserted between the channel
shaped sides which are attached thereto. The socket may be formed of a coil
of wire or a ferrule or the like and the sides may be secured thereto by being
lapped with wire or by a tube or ferrule placed over them. The end may be
further secured by brazing soldering or dipping in molten metal such as lead
solder or galvanizing metal.
A pin or peg
inserted through the socket the point of which engages with
the sides of the skewer and expands them until they grip or bind with sufficient
tenacity upon the interior of the cop.
The pin or peg may be loose and separately applied to each skewer or may be
mounted on the board or creel of the machine for the skewer to be placed upon
when in the cop or it may form the tongue or peg of a shuttle to receive the cop
with the skewer inserted in it.

I, MARTIN WALSH, of 154, Napier Street, Gorton, Manchester, in the County
of Lancaster, Mechanical Engineer, do hereby declare the nature of this inven
tion and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
-
This invention is designed to provide an appliance for insertion into the
interior of cops of cotton or other yarn to hold it in position during the opera-
tions of spinning winding doubling or otherwise to which the yarn is subjected
which will prevent fraying or disarrangement of the layers of the cop and of the
nose of the cop whilst unwinding and which will provide for the tightening up
slackening of the appliance in the interior of the cop after insertion or
and
or
before withdrawal.
The appliance will be found applicable for holding cops in spinning winding
doubling or other frames or machines and also in the shuttles of looms and the
yarn may be either wound onto or off the appliance.
It consists essentially of an appliance constructed of one two or more flexible
strips of metal of channel or other section forming a shell attached together at
one end and attached or held together at the other by a tubular sleeve or plug
to receive a spindle or pin the flexible sides of the appliance being capable of
being expanded or collapsed by pressure applied internally or externally.
The invention will be fully described with reference to the accompanying
drawings.

Instead
The appliance is made of one two or more preferably two strips or pieces a
of channel steel of semicircular or other convenient cross section forming a
shell A which surrounds a spindle or pin B to which it is applied in use.
of steel bronze hard brass or other flexible metal may be employed.
The flexible strips are attached or connected at one or both ends by brazing
together or to a ferrule or plug or the like leaving an opening or space for the
spindle or pin to pass through.
The appliance will be made in various shapes or forms according to the
particular use to which it is to be applied.
In Figs. 1 and 2 the appliance is shown in the form intended for insertion
into the interior of a finished cop for the purpose of unwinding the yarn there-
from. It is made tapering in form and at one end at c the ends of the two
strips a are brazed or otherwise attached together. At the other end a ferrule 1)

page_text: is inserted of tubular or cylindrical interior to fit over a spindle or pin B upon
which the appliance is supported. The ends of the strips a are brazed or other-
wise secured to the ferrule or sleeve D. When placed over the supporting
spindle or pin B the end of the spindle presses against the interior of the strips a
expanding or forcing them outwards causing them to bind tightly against the
interior sides or layers of the cop. The reverse action takes place on the with-
drawal of the spindle B the appliance A being then readily withdrawn from the
interior of the cop.
In Figs. 3 and 4 the appliance is shown in the form intended for use when a
cop is desired to be wound thereon and which may be subsequently removed
from the cop or the cop unwound therefrom. It is tapering in form and at the
end the strips a are brazed or soldered together over a small ferrule, at the
base or larger end the strips are attached by a ring or ferrule D to which they
are brazed. The two ferrules are made of different sizes to give the desired
amount of taper. Inside the ferrule D is placed a loose plug E to receive and
hold the end 6 of the spindle. Projecting pieces e are secured to the interior of
the strips a to bear against the spindle B to cause the desired expansion when
the spindle (or plug E) is inserted and hold the strips a firm at the centre during
the winding of the yarn and subsequently to permit of them collapsing when
the spindle B (or plug E) is removed. The appliance A is placed upon the
spindle B with the narrow end downwards and the yarn wound thereon the cop
being built from upwards when full the appliance A and cop are together
removed from the spindle. The appliance will then collapse and be withdrawn
from the cop or the plug E may be removed and the appliance may be placed on
another spindle for any subsequent operation. For unwinding it is reversed on
the spindle or onto another spindle.
In Figs. 5, 6 and 7 a modification is shown of the appliance for use merely
to receive the cop as it is wound and from which the cop can subsequently be
readily removed. The strips are attached at the narrower end by brazing
and instead of or in addition to a ferrule they may also be brazed or permanently
attached to the spindle, at the base or broad end the strips a are held together by
a loose ferrule or tube D slipped over them (of paper or other material) which
will be removed with the cop. Inside, a plug E is placed, against which the
strips a are firmly held by the tube D and by which they are secured to the end
of the spindle B. When the сор
is wound upon the strips a the plug E is removed
which allows the strips to collapse and the ready withdrawal of the cop. The
plug E projects down near the spindle and is filled with projections e¹ to support
the strips and allow them to collapse when the plug is withdrawn.
In either of the modifications the socket may be formed of a coil of wire or a
ferrule or the like and the strips a may be secured thereto by being lapped with
wire or by a tube or ferrule placed over them. The end may be further secured
by brazing, soldering or dipping in molten metal such as lead, solder or galvaniz-
ing metal.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. An appliance for holding cops formed of one or more strips of elastic metal
connected at the ends and provided at one or both ends with an aperture through
which a spindle or pin can be inserted for the purpose of expanding the sides
substantially as described.
2. In an appliance for holding or receiving cops the combination with a
spindle of one or more flexible strips of metal held to the spindle at their free
ends by a tube and plug to engage the inner layers of yarn substantially as and
for the purpose described.
3. An appliance for receiving or holding cops of yarn during any of the

page_text: processes to which they are subjected in spinning, winding, doubling or other
frames or in looms, constructed and arranged substantially as described and
shown with reference to either of the figs. of the drawings.
