IMPROVEMENTS IN MACHINERY FOR WINDING AND DOUBLING YARNS
Year: 1853

page_text: LETTERS PATENT to John Crabtree, of Heywood, in the County of
Lancaster, Cotton Spinner, for the Invention of "IMPROVEMENTS
IN MACHINERY FOR WINDING AND DOUBLING YARNS."
Sealed the 23rd March 1853, and dated the 20th January 1853.
PROVISIONAL SPECIFICATION left by the said Jolin Crabtree
at the Office of the Commissioners of Patents, with his Petition,
on the 20th January 1853.
I, JOHN CRABTREE, of Heywood, in the County of Lancaster, Cotton
Spinner, do hereby declare the nature of the said Invention for "IM-
PROVEMENTS IN MACHINERY FOR WINDING AND DOUBLING YARNS" to be
as follows:-
The object of my Invention is to save time in doubling or winding
yarn. In winding machines of the ordinary construction, when an end
breaks, it is customary to stop the whole machine (or, in doublers, the
attendant places his or her knee to the spindle) whilst the broken end
is being pieced; by this means one hundred spindles, or more or less, as
the case may be, are stopped. Now my Invention consists in stopping
any one spindle of the machine at pleasure; for this purpose I propose
to use a friction brake, or to have a collar upon each spindle either
separate or attached to the wharf or the ordinary collar, on which the

page_text: bobbin rests, and which carries the bobbin round, and in hinging a lever
with an opening in it corresponding to the distance between the flat
sides of the collar (as in an ordinary screw wrench), when the spindle is
at work the lever is beyond the reach of the collar, but when an end
breaks the attendant, by moving the lever, brings the opening on to the
collar, thereby effectually stopping the motion of the spindle; the band
by which the spindle is driven slips on its wharf when the end is being
pieced; the attendant then moves the lever into its former position, and
the spindle is at liberty to revolve. By this means the machine only
requires to be stopped, when the full bobbins are ready for being doffed.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Crabtree in the Great Seal Patent Office.
on the 20th July 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JOHN CRABTREE, of Heywood, in the County of Lancaster, Cotton Spinner,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of January, in the year.
of our Lord One thousand eight hundred and fifty-three, in the. six-
teenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Crabtree, Her special licence
that I, the said John Crabtree, my executors, administrators, and
assigns, or such others as I, the said John Crabtree, 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, exer-
cise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "In-
PROVEMENTS IN MACHINERY FOR WINDING AND DOUBLING YARNS," upon the
condition (amongst others) that I, the said John Crabtree, 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 he performed, and cause the same to be filed

page_text: 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. John Crabtree, 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 (that is to say):
My Invention consists in applying to the spindles of machines for
winding, and.doubling yarn a stop lever or break by means of which
each spindles can be stopped individually for the purpose of piccing,
thereby effecting a great saving in time.
And in order that niy Invention may be fully understood, and readily.
carried into effect, I will proceed to describe the means pursued by me,
reference. being had to the annexed Sheet of Drawings, and to the
letters and figures marked thereon.
.. Figure 1, is a sectional end elevation of a winding machine to which
my.improvements are applied. Figure 2, is a plan, and Figure 3, a
front elevation of part of the same. a, a, are the cops, which are to be
wound on the bobbins b, b. These bobbins are mounted on the spindles®
c, c, which are supported in foot steps in the rail d, and in bearings.in
the.bolster e; the yarn is guided from the cops a, to the faller.f, as shewn
in the Drawing, and the spindles c are driven by the drum.g,. in-the
usual manner. All the above-mentioned parts are similar to those in
general use. My improvements consist in the lever h, and braids i,
drawn full size in Figures 4, and 5. The braid i, is fast on the spindle c;
it is furnished above with two projections, which, enter into notches in
the, bottom of the bobbins in the usual manner, and the boss of the
braid is flattened in two places, as shewn best in Figure 5. The lever
h-fits on a stud-fixed-in- the bolster rail e; and it is provided with a notch
large enough to take on to the flattened sides of the boss of the braid i.
The mode of operation is as follows:-When the machine is at work,
and the yarns are all in order, the levers h are moved by the attendant
into the positions shewn in the plan view, Figure 2, at the first, third,
and fourth spindles; but as soon as an end breaks, or a fresh cop is
required, the attendant moves the lever h towards the bobbin, and
brings the notch in the lever h, on to the boss of the braid i, as shewn

page_text: in Figure 5, and in the second spindle of the plan, Figure 2. By this
means the motion of the spindle is arrested until the broken end is
pieced, or a full cop substituted for the empty one; the band by which
the spindle is driven slips on the wharf as long as the lever h catches
the boss of the spindle to be stopped, but all the other spindles of the
frame continue in motion. In winding frames of the ordinary con-
struction it was necessary to stop the whole machine for piecing up an
end, but according to my iinprovement each spindle can be stopped in-
dividually, and the machine only requires to be stopped when the full
bobbins are ready to be doffed, thereby rendering each frame capable of
producing a much greater quantity of work than the frames of the ordi-
nary construction. I have not shewn the application of my improve-
ments to a doubling frame, as any mechanic conversant with this class
of machinery would be able to apply my improvements thereto.
Having now described the nature of my Invention, and one mode of
performing the same, I wish it to be understood that I do not limit my-
self to this particular mode of construction, as the same may be varied
without departing from the peculiar character of my Invention; but
what I claim is, the application of the lever h, and flattened boss of the
braid i, or any other equivalent agents, to the spindles of winding and
doubling frames for the purpose of stopping each spindle independently
of the others.
In witness whereof, I, the said John Crabtree, have hereunto
set my hand and seal, this Sixteenth day of July, One thousand
eight hundred and fifty-three.
