PROVISIONAL SPECIFICATION.
Improvements in Spools, Pirns, and like Bobbins.
We, SAMUEL CLOUGH, of Steeton, in the County of York, Spinner and Manu-
facturer, and TOM DIXON, of Station Road, Steeton, aforesaid, Bobbin Turner,
do hereby declare the nature of this invention to be as follows:-
This invention has for its object the construction of spools, pirns and like
bobbins in such a manner that the bobbin end is strengthened, and for yarn
wound thereon to leave the same more readily and with less liability to breakage
than is the case when constructed in the ordinary manner; also to prevent
the yarn leaving the bobbin in bulk as is sometimes the case when the yarn is
being woven into a fabric.
We accomplish our object in the following manner. Near to what is termed the
nose of the bobbin we form a shallow groove and insert therein a metallic ring of
such section that the outer circumference is above the circumference of the bobbin.
thus binding the wood or the like of which the bobbin is composed and forming
a guide for keeping the yarn as it leaves the bobbin clear of any rough or irregular
places that may be formed at the bobbin nose through use, and thus to reduce the
friction and breakage of the yarn to a minimum as it leaves the bobbin; also by
allowing the metallic ring to project above the circumference of the bobbin, the
same acts as a barrier and thereby prevents the yarn leaving the bobbin in bulk
as is sometimes the case when the bobbin is placed in a weaving shuttle of
a loom, the sudden motion given to the shuttle causing the yarn to move towards
the nose of the bobbin.

Improvements in Spools, Pirns, and like Bobbins.
We, SAMUEL CLOUGH, of Steeton, in the County of York, Spinner and Manu-
facturer, and Toм DIXON, of Station Road, Steeton, aforesaid, Bobbin Turner,
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 has for its object, the construction of spools, pirns and like
bobbins in such a manner that, the bobbin end is strengthened, and for the
yarn wound thereon to leave the same more readily and with less liability to
breakage, than is the case when the bobbin is constructed in the ordinary
manner; and also by our improvement, to prevent the yarn leaving the bobbin in
bulk, as is sometimes the case when the yarn is being woven into a fabric.
In describing our invention in detail, reference is made to the accompanying
sheet of drawings in which,

page_text: Fig. 1, represents an elevation of a spool strengthened and protected in accor-
dance with our invention, and
Fig. 2 is an elevation of the same partly in section.
In the drawing we have only shown one class of bobbins to which our invention
is applicable, but it will be readily understood by persons in the textile industries
using bobbins, that our invention is also applicable to pirns and like bobbins or
tubes on which yarn is wound.
Near to what is termed the nose A of the spool bobbin B or pirn as the case
may be, we form a shallow groove shown by sectional elevation Fig. 2 and insert
therein a metallic ring C of such section that the outer circumference of the ring
projects above the circumference of the bobbin B about half the section of the
said metallic ring being compressed into the shallow groove thus binding together
the wood or the like of which the bobbin is composed, also forming a smooth and
uniform guide for keeping the yarn as it leaves the bobbin clear of any rough or
irregular places that may be formed on the nose A by being knocked or otherwise
damaged.
The metallic ring C is of such internal diameter as to pass over the nose A,
and may be compressed into the before mentioned shallow groove by placing the
end of the bobbin or pirn and metallic ring within a conical socket, so that on
forcing in any convenient manner, the bobbin or the like and metallic ring C
towards the small end of the said socket, the metallic ring C is pressed against the
shoulder forming one side of the before mentioned groove, and by the continued
forward movement of the bobbin or the like and metallic ring, the latter is con-
tracted in diameter and compressed into the before mentioned shallow groove.
By the application of a metallic ring C in the manner and for purposes
described, and forming the external circumference of same curved as shown or
with a narrow edge, the friction on the yarn as it leaves the bobbin or pirn and the
liability of breakage of same is reduced; also the protruding portion of the ring
acts as a barrier and thereby prevents the yarn stripping or leaving the bobbin
in bulk, as is sometimes the case when the bobbin or the like is placed in the
weaving shuttle of a loom; the sudden motion given to the shuttle in some cases
causing the yarn to move in bulk towards the nose of the bobbin or pirn.
In the foregoing description we have referred to the strengthening ring C
being secured near to the bobbin nose, by compressing part of the section of the
ring into a shallow groove, but it will be obvious that a narrow metallic ring
with its outer circumference projecting above the circumference of the bobbin,
may be secured near to the bobbins nose without the formation of a shallow groove,
that is, by compressing the ring so as to embrace the circumference of the
bobbin and by the outer circumference of the ring projecting above the bobbin
in the manner shown and described, the nose A is protected, and the delivery
of the yarn from the bobbin when weaving facilitated by reducing the frictional
contact on the yarn.
Having now particularly described and ascertained the nature of our invention,
and in what manner the same is to be performed, we declare that what we
claim is;-
The strengthening and protecting of bobbins by a metallic ring C compressed
partly into the respective bobbins in a manner that the outer circumference of the
ring projects beyond the circumference of the bobbin substantially in the
manner as shown and described, and for the purposes as herein before set forth.
