IMPROVEMENTS IN BOBBINS ADAPTED FOR USE IN THE SPINNING OF FIBROUS MATERIALS
Year: 1878

page_text: LETTERS PATENT to William Wood, of Dukinfield, in the County of
Lancaster, Bobbin-maker, for the Invention of "IMPROVEMENTS IN BOBBINS
ADAPTED FOR USE IN THE SPINNING OF FIBROUS MATERIALS."
Sealed the 20th June 1879, and dated the 24th December 1878.
PROVISIONAL SPECIFICATION left by the said William Wood at the Office
of the Commissioners of Patents on the 24th December 1878.
WILLIAM WOOD, of Dukinfield, in the County of Lancaster, Bobbin Maker.
"IMPROVEMENTS IN BOBBINS ADAPTED FOR USE IN THE SPINNING OF FIBROUS
MATERIALS."
My Invention relates principally to the bobbins used in roving machines, and in
other machines employed in the spinning of cotton and other fibrous materials.
The said bobbins are of a hollow cylindrical form. The objects of my Invention
are to reduce the weight of such bobbins and to render them more durable. To
this end I make a tubular barrel, as is usual, but I bore or form the hole which
extends from end to end of the bobbin larger in diameter than is usual. To the
end which is to be the lower end of the bobbin I secure a suitable metallic ferrule.
I reduce the upper end of the bobbin in diameter suitably to receive a metallic
hoop, which is forced on to the end of the bobbin. In the same end of the bobbin
I drive or force a plug formed of wood, paper, or other suitable material. The said
plug is bored to fit the spindle of the spinning machine, or is otherwise formed
with a central hole to suit the said spindle. In practice I bore the said plug
to the required size after it has been forced into position within the end of the
bobbin, and subsequently skim the exterior of the bobbin to render it true to the
bore of the said plug. I may also fix a plug in the lower end of the bobbin if
considered to be desirable.

"IMPROVEMENTS IN BOBBINS ADAPTED FOR USE IN THE SPINNING OF FIBROUS
MATERIALS."
My Invention relates principally to the bobbins used in roving machines, and in
other machines employed in the spinning of cotton and other fibrous materials.
The said bobbins are of a hollow cylindrical form. The objects of my Invention
are to reduce the weight of such bobbins and to render them more durable. To
this end I make a tubular barrel, as is usual, but I bore or form the hole which
extends from end to end of the bobbin larger in diameter than is usual. I reduce
the upper end or each end of the bobbin in diameter suitably to receive a metallic
hoop, which is forced on to the end of the bobbin. In the same end of the bobbin
I drive or force a plug or ferrule formed of wood, paper, or other suitable material.
The said plug is bored to fit the spindle of the spinning machine, or is otherwise
formed with a central hole to suit the said spindle.
And in order that my Invention may be fully understood I have appended
hereunto a Sheet of Drawings made about the full size of the examples selected and
marked with letters of reference. Referring to the said Drawings, Fig. 1 is a
longitudinal section of a bobbin formed in accordance with my Invention. In the
said Figure a is the shell of the bobbin, which has a larger internal space and a
smaller outer diameter than are usual, so that the thickness of the shell is reduced
comparatively. Each end of the shell is turned down to receive a metal ring b,
which is forced on to the part so reduced. I have found cast malleable rings to be
suitable, but metal rings or hoops otherwise formed may be used. A wooden
ferule c is turned to fit tightly into the end of the shell a, and is formed with a
flanch or collar of about the same diameter as the shell a. I prefer to apply gluo
to the exterior of the said ferule before driving or forcing it into the end of the
shell, or to otherwise cement it in position. When forced tightly in with the
application of glue the bobbin end is made suitably strong. In practice I use a
comparatively light wood for the shell and a harder wood for the ferule. In the
example both ends of the bobbin are hooped and treated in the same manner, but
in some cases I may make the upper end of the bobbin in accordance with my
Invention and apply a suitable driving ring, ferule, or attachment to the lower end
of the bobbin. In practice I skim up or finish the bobbin after the fixing therein
of the ferules c, whereby an uniform diameter is obtained, and I bore out or finish
the holes in the ferules to suit the size of spindle for which the bobbin is intended.
Fig. 2 illustrates a modification wherein the ferule is not formed with a collar, and
therefore does not extend over the metal ring or hoop. Fig. 3 illustrates another
modification. In this example the said ferule is formed with a collar which exceeds
the shell of the bobbin in diameter, so that a projecting flanch or collar is formed
on the upper end or on each end of the bobbin. Although I consider hard or tough
wood to be the best material for the ferules, I do not confine myself to this material.
By the means indicated I obtain a lighter bobbin and an increase in durability, as
the metal rings or hoops check the tendency of the bobbin to split.
Having now fully set forth and indicated the nature of my said Invention, and
the manner in which I carry the same into practical effect, I would have it to be
understood in conclusion that I claim with reference to bobbins of the description
indicated,―
First. The method of making bobbins, substantially as set forth and indicated
hereinbefore and in and by the accompanying Drawings.
And, Secondly. Applying an encircling metal ring or hoop to the exterior of the

page_text: bobbin at one end, or at each end, and forcing into the end so treated a hard or tough
wood plug or ferule which has been or is subsequently bored to suit the size of
spindle for which the bobbin is intended, substantially as set forth and indicated.
In witness whereof, I, the said William Wood, have hereunto set my hand
and seal, this Twenty third day of June, in the year of our Lord One
thousand eight hundred and seventy nine.
