IMPROVEMENTS IN THROSTLE AND DOUBLING FRAMES FOR OPINNING AND DOUBLING FIBROUS MATERIALS.
Year: 1861

page_text: LETTERS PATENT to Thomas Butterworth Collingwood, Manager, and
Abraham Butterworth, Overlooker, both of Rochdale, in the County of
Lancaster, for the Invention of "IMPROVEMENTS IN THROSTLE AND DOUBLING
FRAMES FOR OPINNING AND DOUBLING FIBROUS MATERIALS.
Sealed the 6th May 1862, and dated the 13th November 1861.
PROVISIONAL SPECIFICATION left by the said Thomas Butterworth
Collingwood and Abraham Butterworth at the Office of the Com-
missioners of Patents, with their Petition, on the 13th November
1861.
We, THOMAS BUTTERWORTH COLLINGWOOD, Manager, and ABRAHAM
BUTTERWORTH, Overlooker, both of Rochdale, in the County of Lancaster,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THROSTLE AND DOUBLING FRAMES FOR SPINNING AND DOUBLING FIBROUS MATERIALS,"
to be as follows:-
In the ordinary throstle spinning and doubling frames when a bobbin does
not properly wind up the thread as delivered by the rollers owing to some
obstruction the thread "snarls" or "curls up," and in many cases breaks and
"flys," so that the broken thread catches upon the adjoining threads, and either
produces an imperfection in them or breaks them down, the breaking 'and
"flying" of one thread frequently causing the next adjoining thread to "snarl"

page_text: and break down other threads, and when the threads are broken the material
delivered by the rollers in many cases will "lap" upon them, and if not
immediately attended to the top roller will be lifted at one end by the lap,
which will cause the other end of the roller (in throstles) to draw the
sliver or slivers for the adjoining thread imperfectly, and thus produce an
uneven thread.
The object of our Invention is to remedy these defects wholly or partly by
certain arrangements, which will in many, if not in all cases, catch the "snarl'
of the thread when it begins to form, or catch the thread when broken, and
prevent it from flying and breaking or rendering other adjoining threads
imperfect, and will at the same time prevent the material delivered by the
rollers from "lapping" round them.
Our Invention for this object consists in making the upper end of the
spindle project above the top of the flyer, and in forming thereon a flange or
flanges, groove or grooves, or it consists in making or forming a projection
above the boss of the "flyer," and in forming thereon a flange or flanges,
groove or grooves, which will take hold of the thread when a "snarl" begins to
form, or when it happens to break, so that the thread will accumulate till
attended to by the "piecer" on this said projection in the form of waste
thread.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Thomas Butterworth Collingwood and Abraham Butterworth
in the Great Seal Patent Office on the 13th May 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
BUTTERWORTH COLLINGWOOD, Manager, and ABRAHAM BUTTERWORTH, Over-
looker, both of Rochdale, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of November, One thousand eight
hundred and sixty-one, in the twenty-fifth year of Her reign, did, for
Herself, Her heirs and successors, give and grant unto us, the said Thomas
Butterworth Collingwood and Abraham Butterworth, Her special license
that we, the said Thomas Butterworth Collingwood and Abraham Butter-
worth, our executors, administrators, and assigns, or such others as we,
the said Thomas Butterworth Collingwood and Abraham Butterworth;
our executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all tiines thereafter during the term

page_text: 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 THROSTLE AND DOUBLING
FRAMES FOR SPINNING AND DOUBLING FIBROUS MATERIALS," upon the condition,
(amongst others) that we, the said Thomas Butterworth Collingwood
and Abraham Butterworth, by an instrument in writing under our hands
and seals, or under the hand and seal of one of us, 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Thomas Butterworth Collingwood and
Abraham Butterworth, do hereby declare the nature of our 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:-
In the ordinary throstle spinning and doubling frames, when a bobbin does
not properly wind up the thread as delivered by the rollers, owing to some
obstruction, the thread "snarls" or "curls up," and in many cases breaks and
flies, so that the broken thread catches upon the adjoining threads and
either produces an imperfection in them or breaks them down, the breaking
and flying of one thread frequently causing the next adjoining thread to snarl
and break down other threads, and when the threads are broken the material
delivered by the rollers in many cases will "lap" upon them, and if not imme-
diately attended to the top roller will be lifted at one end by the lap, which
will cause the other end of the roller (in throstles) to draw the sliver or slivers
for the adjoining threads imperfectly, and thus produce an uneven thread.
The object of our Invention is to remedy these defects, wholly or partly, by
certain arrangements, which will in many, if not all cases, catch the "snarl"
of the thread when it begins to form, or catch the thread when broken, and
prevent it from flying and breaking or rendering other adjoining threads
imperfect, and will at the same time prevent the material delivered by the
rollers from "lapping" round them.
Our Invention for this object consists in making the upper end of the
spindle project above the top of the flyer and forming thereon a flange or
flanges, groove or grooves, or it consists in making or forming a projection on
the top or above the boss of the flyer, and in forming thereon a flange or
flanges, groove or grooves, which will take hold of the thread when the snarl
begins to form, or when it happens to break, so that the thread will accumulate

page_text: on or about this said projection in the form of waste thread till attended to by
the "piecer."
Fig. 1 shews the manner in which we form the flange on the top of the
spindle with a common flyer; Fig. 2 represents the mode of forming the top
of the spindle when made with our patent long-bossed and quick-threaded
screw, the single thread (a¹) in this case terminating in the groove which
forms the shoulder or flange on the top of the spindle; Fig. 3 shews our
patent long-bossed and quick-threaded flyer and spindle, with the flange on
the boss of the flyer, this flange also serving for the purpose described in the
Specification of our Patent, dated the "11th October, A.D. 1861," and
numbered "2542"; Figs. 4, 5, and 6, shew applications to our patent flyer or
to common flyers for accomplishing the object of our Invention. In Fig. 4
the part applied is brazed or otherwise secured on the top of the boss of
the flyer; Fig. 5 is made with a socket to fit on the boss of the flyer; Fig. 6
is the same as Fig. 5, except that it is tubular..
In each Figure of the Drawings a is the spindle; b, flyer; c, flange on the
end of the spindle or upon the part formed upon or applied to the flyer.
We have now particularly described the nature of our Invention and the
manner in which the same is carried into effect, and claim the construction of
spindles or flyers for spinning or doubling, in the manner and for the purpose
herein-before described.
In witness whereof, I, the said Thomas Butterworth Collingwood, on
my own behalf and on behalf of the said Abraham Butterworth, have
hereunto set my hand and seal, this Twelfth day of May, in the
year of our Lord One thousand eight hundred and sixty-two.
T. B. COLLINGWOOD. (L.S.)
