Improvements in the Construction of Spools, Pirns, and Bobbins
Used in Machines for Preparing, Spinning, Winding, Twisting,
or otherwise Treating Fibrous Materials.
We, JOSEPH BRIGGS SWAILES, GEORGE SWAILES and JOHN BROAD-
MEADOW SWAILES, of the Firm of John Swailes & Sous of Moorhey, Oldham,
in the County of Lancaster, Cop Tube Manufacturers and Machinists, do hereby
declare the nature of the said invention, to be as follows:---
Firstly. Our invention refers more particularly to spools or bobbins made
of paper, used for ring spinning or doubling, the lower ends of which spools or
bobbins fit into a cup which holds and drives them on the spindle of the ring
spinning or doubling frame.
Such bobbins or spools made of paper are liable to become soft and to break at
the tips.
This part of our invention consists in applying a hoop of metal or other material,
to the tips of paper spools or bobbins for the purposes above named, which makes
such paper spools or bobbins strong, and protects them against wear and tear and
friction of the thread.
Secondly. Our invention relates to bobbins made of paper, such as are used in
machines for preparing fibrous materials known as slubbing, intermediate and
roving frames, and consists in strengthening such bobbins made of paper by hoops
applied at the tops and to the bottom and to the flanges or heads thereof.
Thirdly. Our invention relates to bobbins or pirns having heads or flanges at
one or both ends, and consists in applying to pirns having flanges or heads at one
end only, a hoop of metal upon the edge of the flange or head and a hoop of metal
at the tip of such pirns or bobbins made of paper to strengthen and protect them
against wear and tear, and our invention further consists in applying hoops of
metal to the heads or flanges of bobbins made of paper having a head or flange
at both ends, to strengthen and protect the edges of the heads or flanges of such
bobbins.

Improvements in the Construction of Spools, Pirns, and Bobbins
Used in Machines for Preparing, Spinning, Winding, Twisting,
or otherwise Treating Fibrous Materials.
We, JOSEPH BRIGGS SWAILES, GEORGE SWAILES and JOHN BROAD-
MEADOW SWAILES of the Firm of John Swailes & Sons of Moorhey, Oldham,
in the County of Lancaster, Cop Tube Manufacturers and Machinists, 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:-
Firstly. Our invention refers more particularly to spools or bobbins made of

page_text: paper, used for ring spinning or doubling, the lower ends of which spools or
bobbins fit into a cup which holds and drives them on the spindle of the ring
spinning or doubling frame.
Such bobbins or spools made of paper are liable to become soft and to break at
the tips.
This part of our invention consists in applying a hoop of metal or other material
to the tips of paper spools or bobbins for the purposes above named, which makes
such paper spools or bobbins, strong, and protects them against wear and tear and
the friction of the thread.
Secondly. Our invention relates to bobbins made of paper such as are used in
machines for preparing fibrous materials known as slubbing, intermediate and
roving frames, and consists in strengthening such bobbins made of paper by hoops
applied at the tops and to the bottom, and to the flanges or heads thereof.
Thirdly. Our invention relates to bobbins or pirns having heads or flanges at
one or both ends, and consists in applying to pirns having flanges or heads at one
end only, a hoop of metal upon the edge of the flange or head, and a hoop of metal
at the tip of such pirus or bobbins made of paper to strengthen and protect them
against wear and tear, and our invention further consists in applying hoops of
metal to the heads or flanges of bobbins made of paper having a head or
flange at both ends, to strengthen and protect the edges of the heads or flanges of
such bobbins.
Fig. 1, is a side view of a ring spinning spool, part of the tip where the hoop is
applied being shown in section according to the first part of our invention.
This spool a,
is made of paper in the ordinary manner of making such paper
spools and has a hoop of metal or other suitable material a¹, applied to the
exterior of its tip, this hoop being secured thereon by two or more indents (such
indents as can be made by a cone centre punch) in the outside of the metal of the
hoop after it has been applied to the tip of the spool, which indents press into the
paper of the spool.
Fig. 2, is a side view of a paper roving or intermediate spool or bobbin, parts
of each end where the hoop of metal or other suitable material is applied being
shown in section.
Fig. 3, is a side view of a puper slubbing spool or bobbin, one end where one
hoop of metal or other suitable material is applied being shown in section.
In Fig. 2, a, is the bobbin formed of paper in the ordinary manner and has a
hoop a', of metal applied to the exterior of its top end, secured as herein before
explained in reference to Fig. 1, or by pins or rivets, and also a hoop of
metal a², applied to the bottom end, and secured in like manner, this bottom
hoop a², having slots a³, for the pins or projections from the part on the spindle, or
part which drives the spool or bobbin.
In Fig. 3, the ends of the spool or bobbin a, have hoops of metal a¹ and a²,
applied, which are long enough when placed thereon to allow the metal to be bent
or turned over the shoulder a', formed on the ends of the spools or bobbins.
Fig. 4, shows a side view of a ring doubling bobbin a, the small head partly
shown in section and protected by a metal hoop a¹. The lower or large end of the
bobbin may be hooped in like manner, if desired.
Fig. 5, is a side view of a pirn a, with the head end partly shown in section.
The head is hooped, and the hoop a², may be secured to the head by being
turned over the edge of the head (which is taper) on the inside as shown, or
otherwise.
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 :-
1. The construction of ring spinning and doubling bobbins or spools of paper
· combined with hoops of metal or other suitable material on the tips, substantially

page_text: 2. The construction of roving, intermediate and slubbing bobbins or spools of
paper combined with hoops of metal or other suitable material at the ends,
substantially as hereinbefore described and illustrated by Figs. 2 and 3 of the
drawings.
3. The construction of ring doubling bobbins and pirus of paper, combined
with a hoop or hoops of metal or other suitable material substantially as herein-
before described and illustrated by Figs. 4 and 5 of the drawings.
