Year: 1878

page_text: LETTERS PATENT to John William Wilson, of Barnsley, in the County of
York, Timber Morchant and Bobbin Manufacturer, for the Invention of
"CERTAIN IMPROVEMENTS IN THE CONSTRUCTION OF BOBBINS, TUBES, OR
SPOOLS"
Sealed the 20th December 1878, and dated the 9th October 1878.
PROVISIONAL SPECIFICATION left by the said John William Wilson at the
Office of the Commissioners of Patents on the 9th October 1878.
JOHN WILLIAM WILSON, of Barnsley, in the County of York, Timber Merchant
and Bobbin Manufacturer. "CERTAIN IMPROVEMENTS IN THE CONSTRUCTION OF
BOBBINS, TUBES, OR SPOOLS."
My Invention has special reference to bobbins, tubes, or spools mainly used in
machinery for preparing and spinning cotton, and has for its object to make the
said bobbins, tubes, or spools stronger and more durable. For this purpose I press
on to the end or ends of these bobbins, tubes, or spools a metalic hoop or ferule in
which are provided the requisite groves or recesses corresponding to those in the
bobbin, tube, or spool, whereby they are, with the pinion on the machine spindles,
carried round together. This Invention may be adapted to other purposes.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John William Wilson in the Great Seal Patent Office on the 9th
April 1879.
JOHN WILLIAM WILSON, of Barnsley, in the County of York, Timber Merchant
and Bobbin Manufacturer. "CERTAIN IMPROVEMENTS IN THE CONSTRUCTION OF
BOBBINS, TUBES, AND SPOOLS."
My Invention relates to an improved metallic ferrule or hoop and its peculiar
application to bobbins, tubes, or spools mainly used in machinery for cotton
Drvice Ad

page_text: preparing and spinning. Compared with other Inventions, which have for their
object, by metal hoops of a similar character, the increased strength and durability
of bobbins, tubes, or spools, this ferrule or hoop can be much more firmly and
securely pressed on to the bobbin, tube, or spool, and from its peculiar construction
in malleable metal is most likely to retain its firmness even when subject to rough
usage or any slight shrinking of the bobbin, tube, or spool when made from wood,
&c., thus imparting continued strength and durability. Objections have been
taken to other Patent Inventions which are obviated in this arrangement. Wood
bobbins, tubes, or spools being absorbents of oil have frequently been taken in
preference to those strengthened by metal, the metal hoop has received on to its
surface the dirty black grease dispelled from the bobbins wheel or journal on the
long collar, and in doffing the full bobbins into skips, bins, &c., much damage has
been done to the yarn by contact with the dirty oil retained on the hoops, whereas
this Invention secures all the advantage of the metallic hoop and admits of the
wood tube absorbing the grease. In consequence of the mischief referred to large
quantities of new bobbins or tubes after a short time working have been cast aside.
In order that my Invention may be understood in detail I have hereunto annexed
one Sheet of Drawings. Fig. 1 is a full view of bobbin, tube, or spool shewing my
improved metallic ferrule or hoop upon it, and Fig. 2 is a sectional view of the same;
Fig. 3 is a plan view as seen from below.
The bobbin, tube, or spool A is turned conical at the bottom end, and the
ferrule or hoop C is pressed on to the bobbin A at B, and at the same time
the serrated edges of the ferrule or hoop C are bent over and clenched into the
recess d at the end of the bobbin A. This may be done by a strong press in a
suitable lathe by guide and milling rollers or other convenient manner. Fig. 4 is a
side view and Fig. 5 is a plan view of the ferrule or hoop which I propose chiefly
to use; it has a conical hole, and the external is conical. Fig. 6 is a side view and
Fig. 7 is a plan view of another modification of my metallic hoop with a conical
hole and the outer diameter parallel; also Fig. 8 is a side view and Fig. 9 is a plan
view of another modification of my metallic hoop or ferrule, shewing a head or
flange E with a conical hole. In the metallic ferrule or hoops I provide one or
more midfeathers F, as shewn in Figs. 4 and 5.
Having thus stated the nature of my Invention, together with the manner of
carrying the same into practical effect, I wish it to be distinctly understood that I
do not intend to limit myself to the details given, as this Invention may be modified
and adapted to other useful purposes; but I claim an improved metallic ferrule or
hoop with a conical hole, and the novel manner of application in bending over the
serrated edge, and as shewn in the Drawings annexed.
In witness whereof, I, the said John Williamn Wilson, have hereunto set my
hand and seal, this Ninth day of April, in the year of our Lord One thousand
eight hundred and seventy-nine.
Signed, sealed, and delivered by the
said John William Wilson in the
presence of
