CERTAIN IMPROVEMENTS IN THE CONSTRUCTION OF BOBBINE
Year: 1871

page_text: LETTERS PATENT to Henry Southwell, of Rochdale, in the County
of Lancaster, for the Invention of "CERTAIN IMPROVEMENTS IN THE
CONSTRUCTION OF BOBBINE."
Sealed the 6th February 1872, and dated the 29th August 1871.
PROVISIONAL SPECIFICATION left by the said Henry Southwell
at the Office of the Commissioners of Patents, with his Petition,
on the 29th August 1871.
I, HENRY SOUTHWELL, of Rochdale, in the County of Lancaster, do
hereby declare the nature of the said Invention for "CERTAIN IMPROVE-
MENTS IN THE CONSTRUCTION OF BOBBINS," to be as follows:-
My Invention relates to the bobbins used in machinery employed
in the preparation of cotton, and has for its object to render the said
bobbins more durable. For this purpose I adapt the lower end of the
said wooden bobbin to receive a collar or shield of iron, brass, zinc, or
other metal, and I fix an iron, brass, zinc, or other metal collar or shield
on the lower end of the wood barrel of the bobbin, the said collar being

page_text: formed with the usual grooves or notches to receive the carriers. The
part of the bobbin most exposed to wear being thus formed of iron,
brass, zinc, or other metal, instead of wood as usual, the durability of
the bobbin is greatly increased. The bottom part of the bobbins is
made of smaller diameter than usual to receive the collar or shield,
which is or may be composed of two metal rings, one fitting within
the other, whereof the outer ring embraces the lower part of the bobbin,
and the inner ring covers the bottom edge of the bobbin. The requisite
grooves or notches to receive the carriers are made in both rings.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Southwell in the Great Seal Patent Office
on the 28th February 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
SOUTHWELL, of Rochdale, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by. Her
Letters Patent, bearing date the Twenty-ninth day of August, in the
year of our Lord One thousand eight hundred and seventy-one, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Henry Southwell, Her special license
that I, the said Henry Southwell, my executors, administrators, and
assigns, or such others as I, the said Henry. Southwell, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times therçafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "CERTAIN IMPROVE-
MENTS IN THE CONSTRUCTION OF BOBBINS," upon the condition (amongst
others) that my, the said Henry Southwell, my executors or adminis-
trators, by an instrument in writing under my, or their, or one of their
hands and seals, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be per-
formed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of
the said Letters Patent.

page_text: NOW KNOW YE, that I, the said Henry Southwell, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement and accompanying Drawings, that is to say:-
My Invention relates to the bobbins used in machinery employed in
the preparation of cotton and other fibrous materials, and has for its
object to render the said bobbins more durable. For this purpose I
adapt the lower end of the said wooden bobbin to receive a collar or
shield of iron, brass, zinc, or other metal, and I fix an iron, brass, zinc,
or other metal collar or shield on the lower end of the barrel of the
bobbin, the said collar being formed with the usual grooves or notches
to receive the carriers. The part of the bobbins most exposed to wear
being thus formed of iron, brass, zinc, or other metal instead of wood as
usual, the durability of the bobbin is greatly increased. The bottom part
of the bobbin is made of smaller diameter than usual to receive the collar
or shield, which may be formed in one piece, or may be composed of
two metal rings, one fitting within the other, whereof the outer ring,
embraces the lower part of the bobbin, and the inner ring covers the
bottom edge of the bobbin. The requisite grooves or notches to receive
the carriers are made in both rings.
In order that the Invention may be better understood and explained
in detail I have hereunto annexed one Sheet of Drawings, the Figures
being drawn about full size, and similar letters of reference being.
marked upon corresponding parts in such Figures.
Fig. 1 represents a sectional view of a wooden bobbin to which the
metal collar or shield is attached, Fig. 2 is an elevation, and Fig. 3 a
sectional plan of the same; Fig. 4. is a plan view of the bobbin as seen
from below.
In these Figures a represents the wooden bobbin, the bottom part of
which is made of smaller diameter than usual, and to the said bottom
part the collar or shield 6 of iron, brass, zinc, or other metal is secured;
the said collar or shield 6 is made in the shape of an angular ring, and
on its internal circumference suitable projections c are provided, in
which the usual grooves or notches d to receive the carriers are formed.
By thus forming that part of the bobbin most exposed to wear of metal
instead of wood as usual it is protected against injury and the durability
of the bobbin is greatly increased.

page_text: Figs. 5, 6, and 7 represent the metal collar or shield in detail, Fig. 5
being a sectional view, Fig. 6 an elevation, and Fig. 7 a plan of the
same, and showing more clearly on the internal circumference of the
collar or shield the projections c in which the grooves or notches d are
formed.
In another arrangement or modification of the collar or shield herein-
before described, the same may be composed of two metal rings one
fitting within the other, whereof the outer ring embraces the lower part
of the bobbin, and the inner ring covers the bottom edge of the bobbin ;
the requisite grooves or notches to receive the carriers are formed in
both rings.
Having now described the nature of my said Invention, together with
the method of carrying the same into practical effect, I wish it to be
distinctly understood that I claim the novel employment, construction,
and use of metal collars or shields on the lower part of the wooden
bobbins used in machinery employed in the preparation of cotton and
other fibrous materials, substantially as and for the purpose herein-
before described and illustrated by the Drawings annexed.
In witness whereof, I, the said Henry Southwell, have hereunto
set my hand and seal, this Seventh day of February, in the
year of our Lord One thousand eight hundred and seventy-two.
Witness.
