Year: 1869

page_text: LETTERS PATENT to Thomas Sowden, of No. 6, Moor Crescent, in the
Township of Hunslet, in the Borough of Leeds, in the County of
York, Gill and Comb Manufacturer, and Joseph Newton, of Leeds,
in the said County, Machine Maker, for the Invention of "IM-
PROVEMENTS IN BOBBINS, AND IN REGULATING THE MOTION OF BOBBINS IN
MACHINERY FOR PREPARING, SPINNING, DOUBLING, WARPING, AND REELING
FLAX, COTTON, AND OTHER FIBRES, AND IN OTHER MACHINERY IN WHICH
BOBBINS ARE USED."
Sealed the 10th August 1869, and dated the 25th March 1869.
PROVISIONAL SPECIFICATION left by the said Thomas Sowden and
Joseph Newton at the Office of the Commissioners of Patents, with
their Petition, on the 25th March 1869.
We, THOMAS SOWDEN, of No. 6, Moor Crescent, in the Township of
Hunslet, in the Borough of Leeds, in the County of York, Gill and
Comb Manufacturer, and JOSEPH NEWTON, of Leeds, in the said County,
Machine Maker, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN BOBBINS, AND IN REGULATING THE MOTION OF BOBBINS IN

page_text: MACHINERY FOR PREPARING, SPINNING, DOUBLING, WARPING, AND REELING FLAX,
COTTON, AND OTHER FIBRES, AND IN OTHER MACHINERY IN WHICH BOBBINS ARE
USED," to be as follows:-
In spinning frames as now commonly constructed upright spindles
are used, on which are placed bobbins, and round the bobbin a flyer
affixed to the top of the spindle revolves. A piece of string to which a
weight is attached presses in a groove on one side of an end of the bobbin,
the action of the string being to prevent the bobbin revolving as rapidly
as the spindle and flyer.
In the arrangement now generally in use the string presses the bobbin
unequally against the spindle, causing wear of both and irregularity of
motion, which causes the breaking of the rove yarn or thread.
Our improvement has for its object to obtain the requisite drag
without subjecting the spindle to lateral pressure by the bobbin. This
we effect by placing at the bottom of each bobbin a plate or collar of
soft iron, and supporting the bobbin on a small magnet, either a simple
steel magnet of the ordinary horse-shoe shape, or upon pieces of iron
rendered magnetic by contact with a steel magnet suitably attached to
them. Such arrangement for retarding the motion of bobbins by
friction regulated by magnetic attraction is useful for a great many
other purposes where thread has to be wound or unwound on bobbins,
such as roving, spinning, twisting, reeling, and warping machines.
Instead of applying iron to the bottom of the bobbin, the bobbin
may be made to fit upon a socket duly arranged for acting with the
magnet.
In some cases instead of making the bobbin of wood and iron as
before mentioned, we find it advantageous to make the bobbin of
vulcanite or preparations of india-rubber, gutta percha, or other similar
gums. With such material we are able to introduce the necessary
portion of iron into a mould in which the foot of the bobbin is formed,
and the iron so introduced may be a plate or coller, or in the shape of
wire or of filings mixed up in the substance of the vulcanite or similar
material.

filed by the said Thomas Sowden and Joseph Newton in the Great
Seal Patent Office on the 25th September 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
SOWDEN, of No. 6, Moor Crescent, in the Township of Hunslet, in the
Borough of Leeds, in the County of York, Gill and Comb Manufacturer,
and JOSEPH NEWTON, of Leeds, in the said County, Machine Maker,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fifth day of March, in the year
of our Lord One thousand eight hundred and sixty-nine, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Thomas Sowden and Joseph Newton,
Her special licence that we, the said Thomas Sowden and Joseph
Newton, our executors, administrators, and assigns, or such others as
we, the said Thomas Sowden and Joseph Newton, our exccutors,
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, AND IN REGULATING THE MOTION OF BOBBINS IN MACHINERY FOR
PREPARING, SPINNING, DOUBLING, WARPING, AND REELING FLAX, COTTON, AND
OTHER FIBRES, AND IN OTHER MACHINERY IN WHICH BOBBINS ARE USED," upon the
condition (amongst others) that we, the said Thomas Sowden and Joseph
Newton, our executors or administrators, by an instrument in writing
under our or their hands and seals, or under the hand and scal
of one of us or them, 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 we, the said Thomas Sowden and Joseph
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 thereof, that is to
say:―

page_text: In spinning frames as now commonly constructed upright spindles
are used, on which are placed bobbins, and around the bobbin a flyer
affixed to the top of the spindle revolves. A piece of string to which
a weight is attached presses in a groove on one side of an end of the
bobbin, the action of the string being to prevent the bobbin revolving
as rapidly as the spindle or flyer.
In the arrangement now generally in use the spring presses the bobbin
unequally against the spindle, causing wear of both and irregularity of
motion which causes the breaking of the rove yarn or thread.
Our improvements have for their object to obtain the requisite drag
without subjecting the spindle to lateral pressure by the bobbin. This
we effect by placing at the bottom of each bobbin a plate or collar of
soft iron, and supporting the bobbin on a small magnet, either a simple
steel magnet of the ordinary horse-shoe shape or upon pieces of iron
rendered magnetic by contact with a steel magnet or an electro-magnet
suitably attached to them. Such arrangement for retarding the motion
of bobbins by friction regulated by magnetic attraction is useful for
a great many other purposes where thread has to be wound or unwound
on bobbins, such as roving, spinning, twisting, reeling, and warping
machines. Instead of applying iron to the bottom of the bobbin, the
bobbin may be made to fit upon a socket duly arranged for acting with
the magnet.
In some cases instead of making the bobbin of wood and iron as
before mentioned, we find it advantageous to make the bobbin of
vulcanite or preparations of india-rubber, gutta percha, or other similar
gums. With such material we are able to introduce the necessary portion
of iron into a mould in which the foot of the bobbin is formed, and
the iron so introduced may be a plate or collar, or in the shape of wire
or of filings mixed up in the substance of the vulcanite or similar
material.
In order that our Invention may be more clearly understood we refer
to the Drawings hereunto annexed which shew the method in which
we prefer to construct machines according to our Invention.
letters in the several Drawings represent similar parts.
Like
In such Drawings, No. 1 is an elevation or view of a spindle and a
apparatus seen from one side; No. 2 is a plan or bird's-eye view of the
same; No. 3 an elevation of parts shewing a front view; No. 4 a section

page_text: of a bobbin, and No. 5 a section of another kind of bobbin made alike
at both ends, so as to be capable of being used either end upwards.
In such Drawings A is a steel spindle of the ordinary kind; B the
ordinary flyer; C, a wooden bobbin having an iron ring D inserted in
the end, but which is shown only in Figures 4 and 5; E, a part of the
framework of what is known as the lifter, and made of brass or any
suitable material, avoiding iron or steel, and having grooves for the
reception and steadying of the magnets F which are steel magnets of
the usual horse-shoe shape, excepting that they are made with inclined
or V-shaped sides so as to slide backwards and forwards on the bed.
A bar G connects several of the magnets together, and a series of
keepers H fixed loosely on a rod I may be applied to the magnets to
preserve the power when not in use, and can also be used to vary the
attraction of the magnets on the bobbins. The attraction of the magnet
on the bobbin can be varied by pulling or pushing back the magnet
in the grooves, the greatest strength being when the bobbin is nearly
over the ends or poles of the magnets. Such method of pushing the
magnet backwards and forwards corresponds with the use of the string
in the ordinary method.
We claim the application of magnets for retarding or regulating the
motion of bobbins in machinery as herein doscribed, and also the
adaptation of the bobbins to work with such magnets as herein described.
In witness whereof, we, the said Thomas Sowden and Joseph
Newton, have hereunto set hand and scal this Twenty-fourth
day of September, in the year of our Lord One thousand eight
hundred and sixty-nine.

the said Thomas Sowden and
Joseph Newton, in the presence of
