Improvements in Bobbins for Ring Frames used for Spinning
Fibrous Materials.
We ALFRED Barlow of No. 9 Worcester Street Mill Manager and JAMES
LEACH of No. 11 George Street Chadderton Ring Frame Overlooker, both of
Oldham in the County of Lancaster do hereby declare the nature of this invention
to be as follows :-
:-
Our invention relates to improvements in the bobbins or tubes used in ring
spinning frames the principal objects of the invention being to produce a more
uniform yarn, and to strengthen the bobbin and render it less liable to injury, and
consequently more durable.
Our invention consists principally in the combination in one and the same bobbin
of three elements or improvements, which, although we are aware that they have
been used separately, have never been combined together in one bobbin.
In the first place, instead of making the bobbin cylindrical from end to end and
only slightly tapered at or near the point, we make the base in a conical form, by
which means the first layer of yarn spun upon the bobbin receives the same amount
of twist as each succeeding layer until the bobbin is full and by this means a more
uniform yarn is produced and bad "gaiting" which is a well known evil in ring-
spinning is thereby entirely overcome.
Secondly we form at the base of this cone a projecting bead which makes the
bobbins much stronger, prevents them from being broken when trodden upon, and
also forms a support or stay for the yarn at the base of the bobbin, thus preventing
what are known as "bad bobbins," as well as preventing the reelers and winders
from pulling the yarn off at the bottom into waste.
Thirdly we form in the base of the bobbin below the bead an annular recess
whereby we are enabled to get the bobbin lower down on the rail, and hence to
put a greater quantity of yarn on a bobbin of a given length; we can also in that
case make the bead wider than heretofore, so that it is stronger and less liable to
become chipped and rough.
We are aware as above stated that each of these features rizt. the cone, the rim
or bead, and the recess have been used before separately, and are known to possess
advantages peculiar to themselves but when adopted separately several defects
present themselves, which have caused them to be used only to a limited extent.
We are also aware that the conical base has been combined with a recess, and it
has also been combined with a rim or bead, but by our invention of combining all
three several improvements in the same bobbin in the manner described we surmount
all the objections hitherto met with, and produce a bobbin superior in many respects
to any that has hitherto been made.
We may remark that this combined bobbin may be made in one or more pieces
as preferred and either of wood papier mache, or other material, and when desirable
the base of the bobbin may be protected by a metal shield formed to fit the same.
Dated this 14th day of April 1892.

Improvements in Bobbins for Ring Frames used for Spinning
Fibrous Materials.
We ALFRED BARLOW of No. 9 Worcester Street Mill Manager and JAMES
LEACH of No. 11 George Street Chadderton Ring Frame Overlooker, both of
Oldham in the County of Lancaster, 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 :—
Our invention relates to improvements in the bobbins or tubes used in ring
spinning frames, the principal objects of the invention being to produce a more
uniform yarn, and to strengthen the bobbin and render it less liable to injury, and
consequently more durable.
The nature of our said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference
to the annexed sheet of drawings and the following explanation thereof.
Fig. 1 is an elevation of one of our improved bobbins and Fig. 2 a section of
the same Fig. 3 is an elevation of a slight modification thereof.
Our invention consists principally in the combination in one and the same bobbin
of three elements or improvements which, although we are aware that they have
been used separately, have never been combined together in one bobbin.
In the first place, instead of making the bobbin cylindrical from end to end, and
only slightly tapered at or near the point, we make the base in a conical form as
shown at a by which means the first layers of yarn spun upon the bobbin receive
a larger amount of twist than it could have with a parallel bobbin, by this means a
more uniform yarn is produced and bad "gaiting" which is a well known evil in
ring-spinning is thereby entirely overcome.
Secondly we form at the base of this cone a projecting bead 6 which makes
the bobbins much stronger, prevents them from being broken when trodden upon,
and also forms a support or stay for the yarn at the base of the bobbin, thus
preventing what are known as bad bobbins as well as preventing the reelers
and winders from pulling the yarn off at the bottom into waste.
"
This bead 6 may be formed light as shown at Figs. 1 and 2 or it may be made
stronger and with a curve running into the cone as shown at Fig. 3.
Thirdly we form in the base of the bobbin below the bead an annular recess c
whereby we are enabled to get the bead lower on the bobbin, and hence to put a
greater quantity of yarn on a bobbin of a given length; we can also in that case
make the bead wider than heretofore, so that it is stronger and less liable to become
chipped and rough.
We are aware as above stated that each of these features vizt.: the cone a the
rim or bead b, and the recess c have been used before separately, and are known
to possess advantages peculiar to themselves, but when adopted separately several
defects present themselves, which have caused them to be used only to a limited
extent.
We are also aware that the conical base has been combined with a recess, and it
has also been combined by us with a rim or bead, larger in diameter than the base
of the cone, as described in the Specification of Letters Patent granted to us
No. 18737 dated December 22nd 1888, but by our present invention of combining
all three several improvements in the same bobbin in the manner described we
surmount all the objections hitherto met with, and produce a bobbin superior in
many respects to any that has hitherto been made.
The combination of a cone and recess in bobbins as previously used has been
found objectionable on account of the large diameter of the base of the bobbin on
which the yarn is wound, causing excessive ballooning of the yarn. By forming
the bobbin with a bead over the recess we are enabled to reduce the diameter of

page_text: the cone part on which the yarn is wound thereby reducing the tendency to excessive
ballooning and obtaining the best results in spinning.
We may remark that this combined bobbin may be made in one or more pieces
as preferred and either of wood papier mache, or other material, and when desirable
the base of the bobbin may be protected by a metal shield formed to fit the same.
Having now particularly described and ascertained the nature of our said inven--
tion and in what manner the same is to be performed we declare that what we
claim is :-
The combination in one and the same bobbin of a conical base a a rim or bead b
and a recess c substantially as hereinbefore described and illustrated by the
drawings annexed.
