Year: 1867

page_text: LETTERS PATENT to William Edward Newton, of the Office for Patents,
66, Chancery Lane, in the County of Middlesex, Civil Engineer, for
the Invention of "IMPROVEMENTS IN BOBBINS POR SPINNING MACHINERY."-
A communication from abroad by the Metallic Bobbin Company (Incor-
PROVISIONAL SPECIFICATION left by the said William Edward Newton
at the Office of the Commissioners of Patents, with his Petition, on the
6th February 1867.
I, WILLIAM EDWARD NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Civil Engineer, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN BOBBINS FOR SPINNING
MACHINERY," to be as follows:
This Invention consists in substituting for the wooden tube hitherto used
in the construction of bobbins for woollen mills a tube constructed of zinc or
other metal which will not rust or corrode.
The Invention also consists in securing the wooden head on the metallic
tube by means of a shoulder and a flange formed by slitting the end of the
tube, and turning up these parts so as to hold on the wooden head. The
interior of the upper end or tip of the tube is formed solid by filling it with

by the said William Edward Newton in the Great Seal Patent Office on
the 6th August 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of February, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
William Edward Newton, Her special licence that I, the said William Edward
Newton, my executors, administrators, and assigns, or such others as I, the
said William Edward Newton, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and at all
times thereafter 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
"IMPROVEMENTS IN BOBBINS FOR SPINNING MACHINERY," being a communication
to me from abroad, upon the condition (amongst others) that I, the said
William Edward Newton, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should particu-
larly describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, 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.
NOW KNOW YE, that I, the said William Edward Newton, do hereby
declare the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the Drawing hereunto annexed,
and to the letters and figures marked thereon (that is to say) :-
This Invention consists in substituting for the wooden tube hitherto used
in the construction of bobbins for woollen mills a tube constructed of zinc or
other metal which will not rust or corrode.
The Invention also consists in securing the wooden head or flange on the

page_text: metallic tube by means of a shoulder and a flange formed by slitting the end
of the tube, and turning up these parts so as to hold on the wooden head.
The interior of the upper end or tip of the tube is formed solid by filling it
with solder, and then boring it out to fit the spindle, so that the tube may be
fitted snugly and properly on the spindle.
The use of a wooden bobbin is attended with several disadvantages. In
the first place the yarn when on the bobbin has to be steamed in order to
prevent it from kinking in weaving, and the steam causes the wood bobbin to
swell and become rough, so that the yarn will adhere to the bobbin and be
broken and wasted. In the second place the wooden bobbins after steaming dry
and shrink so much that frequently the whole "cop" will come off and become
waste. In the third place the wooden bobbins by splitting and breaking
occasion the loss of a considerable sum annually, owing to the great waste of
material. These objections and inconveniences are fully obviated by using
the metallic bobbin.
In the accompanying Drawing, Figures 1, 2 and 3 represent the different
bobbins used in the manufacture of woollen goods, Fig. 1 being a longitudinal
section, and Figures 2 and 3 side views, and Figures 4, 5, and 6 end views of
the same.
The tubes a are constructed of zinc or other non-corrosive metal, zinc
would probably be the cheapest and best material. These tubes are drawn
down to the proper dimensions, and the wooden heads or flanges 6 (Figures
1 and 3) are driven on them against a shoulder c, produced by drawing down
the tube a short distance above b, as will be clearly understood by referring
to Figure 1. The end of the tube at the outer side of 6 is slit, and turned over
in a groove d (as shewn in Figures 1 and 4), or it may be turned over without
being slit. The interior of the upper end of the tube is filled with solder e or
other suitable material, so that the orifices of the tube may be contracted to
suit the spindle; this will be fully understood by referring to Fig. 1. In
lieu of this the tubes may however be drawn with a solid bead or tip, and the
latter drilled out to suit the form of the end of the spindle. The wooden
head or flange b in Figures 2 and 5 being comparatively long will be firmly
secured on its tube by simply driving it snugly thereon.
Having now described this Invention of "Improvements in Bobbins for
Spinning Machinery," and having explained the manner of carrying the same
into effect, as communicated to me by my foreign correspondent, I claim as
the Invention secured to me by Letters Patent as aforesaid,―
First, constructing bobbins of a tube of zinc or other non-corrosive metal
as set forth.

page_text: Second, I claim securing the wooden head or flange on the ends of the
tubes in the manner shewn and described.
Third, contracting the interior of the tips of the metallic tubes to fit the
spindle as set forth.
In witness whereof, I, the said William Edward Newton, have hereunto
set my hand and seal, the Second day of August, in the year of our
Lord One thousand eight hundred and sixty-seven.
Witness,
J. W. MOFFATT,
66, Chancery Lane.
