IMPROVEMENTS IN THE CONSTRUCTION OF RING FRAME BOBBINS FOR THROSTLE SPINNING
Year: 1880

page_text: LETTERS PATENT to Henry Southwell, of Rochdale, in the County of
Lancaster, Bobbin Manufacturer, for an Invention of "IMPROVEMENTS IN
THE CONSTRUCTION OF RING FRAME BOBBINS FOR THROSTLE SPINNING.”
.PROVISIONAL SPECIFICATION left by the said Henry Southwell at the
Office of the Commissioners of Patents on the 20th July 1880.
HENRY SOUTHWELL, of Rochdale, in the County of Lancaster, Bobbin
Manufacturer. "IMPROVEMENTS IN THE CONSTRUCTION OF RING FRAME BOBBINS
FOR THROSTLE SPINNING."
This Invention relates to an improvement in bobbins used for ring spinning, and
consists in fixing to the bottom of the wood bobbin, as in ordinary use, a metalic
boss, which is so constructed externally that, by having the upper portion vandyked
over a somewhat smaller part of the bobbin, the points of the same may be so
compressed as to make the same firm and secure to the bobbin, the lower part of
the metalic boss being shaped to correspond with the socketed portion of the
spindle in which it drops, whilst the interior part is arranged to fit the taper bush
or collar on the spindle as in general use, the bottom of the bobbin being constructed
to drop into a recess formed in the metalic bush for its reception, in such form as
to add to its strength and stability.

an Order of the Lord Chancellor, filed by the said Henry Southwell in the
Great Seal Patent Office on the 28th January 1881.
HENRY SOUTHWELL, of Rochdale, in the County of Lancaster, Bobbin
Manufacturer. "IMPROVEMENTS IN THE CONSTRUCTION OF RING FRAME BOBBINS
_FOR THROSTLE SPINNING."
This indenture relates to an improvement in bobbins used for ring spinning; and
consists in fixing to the bottom of the wood bobbin, as in ordinary use, a metallic
boss, which is so constructed externally that, having the upper portion vandyked
over a smaller part of the bobbin, the points of the same may be compressed, so as
to firmly secure the boss to the bobbin; or this object may be obtained without
vandyking the rim of the metallic boss by simply prolonging the same over tho
shoulder of the bobbin, and, by use of an instrument constructed for the purpose,
compress the overlapping portion of the rim round the upper part of the shoulder
of the bobbin so as to tightly clip the same; or the metallic boss may be secured
by having a groove cut in the bobbiu, into which the edge of the rim could be
compressed in such manner as to firmly secure the metalic boss to the bobbin.
The lower part of the metallic-boss-is-shaped externally to correspond with socketted
portion of the spindle into which it is placed, whilst the interior is constructed to
fit the bottom of the taper bush or collar on the spindle, the bottom of the bobbin
being shaped in accordance with a recess formed in the metallic boss for its
reception, and into which it is placed. It will be readily understood that by the
use of such metallic boss, the bobbin is not merely much strengthened, but that it
will work with a greater degree of steadiness than would be the case without its
UBE.
In order that this Invention may be more clearly understood, I have hereunto
attached a Sheet of Drawings having similar letters of reference, in which Figure I
represents an external view of the bobbin in its place on the spindle, A being the
bobbin, B the metallic boss, C the cup or socket of the spindle D in which the
bobbin rests; Figure 2 is a section of the ordinary bobbin without the metallic boss,
whilst Figure 3 shows a section of the bobbin A with the metallic bush B, and the
cup or socket C of the spindle D; in this Drawing the inner part of the metallic
boss is not shown as tightly fitting the bush or collar of the spindle, this not being
absolutely required to insure stability when in use.
Having thus fully described the nature of my Invention, and the manner in
which it is to be carried out, I claim the application and use of the metallic boss
attached to bobbins for ring spinning.
In witness whereof, I, the said Henry Southwell, have hereunto set my hand
and seal, this Seventeenth day of January, in the year of our Lord One
thousand eight hundred and eighty one.
Witness,
WM. HRY. DAWSON,
Patent Agent,
