IMPROVEMENTS IN SPOOLS OR BOBBINS TO BE USED IN CERTAIN MAMERTATO POR SPINNING
Year: 1865

page_text: LETTERS PATENT to Joshua Henry Wilson, of Cornholme Mill, near
Todmorden, in the County of Lancaster, Bobbin Manufacturer, for the
Invention of "IMPROVEMENTS IN SPOOLS OR BOBBINS TO BE USED IN CERTAIN
MAMERTATO POR SPINNING."
Sealed the 20th October 1865, and dated the 22nd April 1865.
PROVISIONAL SPECIFICATION left by the said Joshua Henry Wilson
at the Office of the Commissioners of Patents, with his Petition, on the
22nd April 1865.
I, JOSHUA HENRY WILSON, of Cornholme Mill, near Todmorden, in the
County of Lancaster, Bobbin Manufacturer, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN SPOOLS OR BOBBINS TO BE USED IN
CERTAIN FRAMES POR PREPARING FIBROUS MATERIALS FOR SPINNING," to be as
follows:-
My Invention relates to slubbing, roving, or jack frames, or to preparing
machinery where the sliver is wound upon the bobbin or spool by a flyer, and
more particularly to such frames as wind the material into a form having
taper or conical ends, which is the result of shortening the length of traverse
as the material enlarges in diameter. In this class of preparing frames the
machine is always stopped when the spools or bobbins are filled at the same

page_text: part of the traverse, that is, at the highest extreme of the shortest traverse, so
that when the empty spools or bobbins are placed upon the spindles the frame
always begins to wind the material upon the spools or bobbins at the same
place, and then traverses to the lowest point of its longest traverse, and then
back over this part of the first layer till it arrives at the place at which it
began to wind, when it comes upon the empty parts of the spools or bobbins,
upon which it continues till it arrives at the highest extremo of its greatest
traverse. It will thus be seen that there is an extra layer of material upon
one end of the spool or bobbin, and that the sliver will wind slack, owing to
the smaller diameter upon that part where the one layer is deficient.
Now my Invention consists in adapting bobbins or spools to this class of
preparing frames, so as to remove the defect above mentioned, which I
accomplish by making the bobbins or spools (which have hitherto been made
of uniform diameter) of larger diameter at that part where the absent layer
occurs to such extent as will compensate for the deficient layer, so that the
second layer will be wound in its entire length of traverse upon a surface of
uniform diameter, by which means slack winding will be obviated. The
spools or bobbins may be made of uniform diameter in the barrel from end to
end, as hitherto, and then a layer of some suitable material may be secured
upon one end of them, but for new spools or bobbins I prefer to turn them of
larger diameter at one end than at the other end.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joshua Henry Wilson in the Great Seal Patent Office
on the 20th October 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSHUA S
HENRY WILSON, of Cornholme Mill, near Todmorden, in the County of
Lancaster, Bobbin Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of April, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Joshua Henry Wilson, Her special license that I, the said Joshua Henry
Wilson, my executors. administrators, and assigns, or such others as I,
the said Joshua Henry Wilson, 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

page_text: 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 SPOOLS OR BOBBINS TO BE USED IN CERTAIN FRAMES FOR
PREPARING FIBROUS MATERIALS FOR SPINNING," upon the condition (amongst
others) that I, the said Joshua Henry Wilson, by an instrument in writing
under my hand and seal, should particularly 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 Joshua Henry Wilson, 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 slubbing, roving, or jack frames, or to preparing
machinery where the sliver is wound upon the bobbin or spool by a flyer, and
more particularly to such frames as wind the material into a form having
taper or conical ends, which is the result of shortening the length of the
traverse as the material enlarges in diameter. In this class of preparing
frames the machine is always stopped when the spools or bobbins are filled at
the same part of the traverse, that is, at the highest extreme of the shortest
traverse, so that when the empty spools or bobbins are placed upon the
spindles the frame always begins to wind the material upon the spools or
bobbins at the same place, and then traverses to the lowest point of its
longest traverse, and then back over this part of the first layer till it arrives
at the place at which it began to wind, when it comes upon the empty parts
of the spools or bobbins, upon which it continues till it arrives at the highest
extreme of its greatest traverse. It will thus be seen that there is an extra
layer of material upon one end of the spool or bobbin, and that the sliver will
wind slack, owing to the smaller diameter upon that part where the one layer
is deficient.
Now my Invention consists in adapting bobbins or spools to this class of
preparing frames, so as to removo the defect above mentioned, which I
accomplish by making the bobbins or spools (which have hitherto been of
uniform diameter) of larger diameter at that part where the absent layer
occurs to such extent as will compensate for the deficient layer, so that the
second layer will be wound in its entire length of traverse upon a surface of
uniform diameter, by which means the slack winding will be obviated. The
spools or bobbins may be made of uniform diameter in the barrel from end to

page_text: end, as hitherto, and then a layer of some suitable material may be secured
upon one end of them; but for new spools or bobbins I prefer to turn them
of larger diameter at one end than at the other end. The accompanying
Drawing will illustrate more fully the nature of my Invention and the manner
of carrying the same into effect.
Figs. 1 and 2 are each side views of the top part of a spindle (a) and of a
presser flyer (6), spool (c), and wheel (d) for giving motion to it. The
spindle (a) is supposed to work in a long collar (a). Fig. 1 shews the
empty spool or bobbin (c) when placed upon the spindle, and Fig. 2 the spool
or bobbin (c) when filled, the spool or bobbin (c) and flyer (b) in each Figure
being shewn in that position which they occupy in relation to each other when
the spool or bobbin is filled, and when the frame is stopped to change the
bobbins or spools. The material begins to wind upon the empty spool at that
point of the traverse where it ceases to wind upon the full spool, namely, at
(1); it then traverses to (2), and then backwards to (3), that part of the
bobbin or spool between 1 and 3 being made so much larger in diameter (as
shewn) as shall be equal to the thickness of one layer of the material when
wound upon the spool or bobbin.
I have now particularly described the nature of my Invention, and the
manner of carrying the same into effect, and claim as my Invention, spools or
bobbins formed in the manner and for the purpose herein-before described.
In witness whereof, I, the said Joshua Henry Wilson, have hereunto set
my band and seal, this Seventeenth day of October, in the year of our
Lord One thousand eight hundred and sixty-five.
Witness,

Patent Agent,
