PROVISIONAL SPECIFICATION,
Improvements in Tubes or Bobbins Used in the Manufacture of
Cotton, Wool, or other Fibrous Material
I JOHN HEGINBOTTOM Commercial Traveller 67 Nile Street Oldham in the County
of Lancaster do hereby declare the nature of this invention to be as follows:-
This invention relates to the hooping of tubes or spools usually called bobbins,
employed in the preparation of cotton, wool or other fibrous material. Hitherto
tubes of this description have been plain, or protected with malleable iron hoops
which are liable to come off, through the contraction of the material the Tube is
made of. In my invention I strengthen and preserve the end of the Tube or Spool
with a hoop of steel or other metal, the hoop at one end having the driving slots, at
the other end saw teeth, which are turned down at right angles, the hoop is split or
cut, and has to be opened a little to get it on the end of the tube, there
may he al
nick or groove in the tube, where the saw teeth of the hoop fit, when the hoop is
fixed on the end of the tube, the split or cut will still be a little open to allow for
contraction of the tube, the hoop is then further secured by another hoop, ring or
spring, fitting tightly on the top of the first-named hoop, this hoop ring or spring is
also cut or split, so that the two hoops rings or springs combined, will have a firm
grip on the Tube, in some cases I have ridges pressed in the bottom hoop, and in other
cases a groove, also grooves and ridges combined to keep the top hoop ring or spring
in its place, I believe this to be the only hoop that is split or cut, and therefore the
only hoop that will hold firm to its place, with either expansion or contraction of the
material the tube is made of.

COMPLETE SPECIFICATION.
Improvements in Tubes or Bobbins Used in the Manufacture of
Cotton, Wool, or other Fibrous Material.
I JOHN HEGINBOTTOM 67 Nile Street Oldham in the County of Lancaster Commercial
Traveller 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 improvements in tubes or bobbins used in the manufacture
of cotton wool or other fibrous material. Hitherto tubes of this description have
been plain or protected with malleable iron hoops, which are liable to come off
through the contraction of the material the tube is made of.
In my invention I strengthen and preserve the end of the tube or spool with a
hoop of steel or other metal, the hoop at one end having the driving slots, (Fig. 1. 2.
3. 4 & 5) marked S; at the other end saw teeth, which are turned down at right
angles, (Fig. 2 marked T) or in other cases I would press or cut a V-shaped tooili
in the side of the hoop turned inward (Fig. 1 & 4 marked V) to prevent the hoop
turning round on the tube, the hoop is split or cut (Fig. 2. 3. 4 & 5 mark C) and
has to be opened a little to get it on, and when fixed on the end of the tube, the
split or cut will still be a little open, (Fig. 5 C) to allow for contraction.
The hoop
is then further secured by a second hoop ring or spring, which is made of heat
hardened steel, fitting tightlyon the first named hoop, as shown by dotted line (Fig.5 A)
also complete in Figure 8, this hoop ring or spring is also cut or split, so that the two
hoops rings or springs combined will have a firm grip on the tube. In some cases
I have ridges pressed in the first named hoop and in other cases a groove (Fig. 1. 2.
Price S

page_text: 3, 4 & 5 marked G.) also grooves and ridges combined (Fig. 3) to keep the second
hoop ring or spring (Fig. 6 & 7) firmly in its place. I believe this to be the only hoop
that is split or cut, & therefore the only hoop that will hold firm to its place, with
either expansion or contraction of the material the tube is made of.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
(Firstly.) Strengthening and protecting the bobbins and tubes used in the manu-
facture of cotton wool or other fibrous material, by the application of a hoop of steel
or other metal which is split or cut, being of the form set forth herein described &
shown as per (Fig. 1. 2. 3. 4 & 5).
(Secondly.) The hoop applied to tubes or bobbins, as set forth & having the driving
slots at one end, saw teeth at the other, as shown in Fig.2.or in other cases a V shaped
tooth cut or pressed in the side of the hoop as shown in Fig. (1 & 4 marked V).
(Thirdly.) The second hoop ring or spring of heat hardened steel, which is also cut
or split, and fits in a groove of the first named hoop, as herein before described &
shown as per (Fig. 6. 7 & 8.) also grooves and ridges combined as shown in Figure 3.
