Year: 1863

page_text: LETTERS PATENT to William Coare Brocklehurst, of Macclesfield, in the
County of Chester, Silk Manufacturer, Joseph Creighton, and John
Creighton, both of Manchester, in the County of Lancaster, Machinists,
for the Invention of "CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS
FOR WINDING YARNS OR THREADS."
Sealed the 20th May 1864, and dated the 27th November 1863.
PROVISIONAL SPECIFICATION left by the said William Coare Brockle-
hurst, Joseph Creighton and John Creighton, at the Office of the
Commissioners of Patents, with their Petition, on the 27th November
1863.
We, WILLIAM COARE BROCKLEHURST, of Macclesfield, in the County of
Chester, Silk Manufacturer, JOSEPH CREIGHTON, and JOHN CREIGHTON, both
of Manchester, in the County of Lancaster, Machinists, do hereby declare
the nature of the said Invention for "CERTAIN IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR WINDING YARNS OR THREADS," to be as follows:-
Our Invention relates to that description of machinery for winding yarn or
thread called "pin cop winding frames," wherein yarn is wound from the
bobbin "race" or bank on to a wooden "pin" or spool, which is placed on
the shuttle skewer for weaving. Our improvements are designed to dispense
with such wooden spool, and to wind or form the "cops" on the bare spindle,

page_text: which has hitherto been impracticable from a want of apparatus to "shape
the cop. The improvements consist in an arrangement of apparatus to effect
the shaping of the cop as the yarn or thread is wound on, which is constituted
as follows:-The yarn is wound upon the bare spindle and delivered thereto
through an eye at the end of one arm of a bell-crank lever, the other arm of
such lever passing through a bowl running in a vertical slot in a standard.
which receives a reciprocating motion from a cam, crank, or eccentric; by this
means the bell crank is caused to vibrate and to deliver the yarn to form the
cop. The apex or top cone of the cop is surmounted by a cap, which bears
upon it, and which is connected to a bar sliding on guides, and which is
attached to the centre or fulcrum of the aforesaid bell-crank lever. Thus,
when the cop is commencing the cap and bell crank is at its lowest point, and
has its shortest "throw" or "radius" to form the bottom of the cop, but as
the cop increases the cap becomes raised, and also raises the bell crank,
whereby a continually differing "throw" is obtained until the aforesaid sliding
bar rises sufficiently high to come into contact with the bowl, when the radius
and throw becomes regular to "build" or form the cylindrical portion of the
cop. This arrangement is applied to each spindle so as to render them
independent of each other in their action.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Coare Brocklehurst, Joseph Creighton, and John
Creighton in the Great Seal Patent Office on the 27th May 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
COARE BROCKLEHURST, of Macclesfield, in the County of Chester, Silk Manu-
facturer, JOSEPH CREIGHTON, and JOHN CREIGHTON, both of Manchester, in the
County of Lancaster, Machinists, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh day of November, in the year of our
Lord One thousand eight hundred and sixty-three, in the twenty-seventh year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said William Coare Brocklehurst, Joseph Creighton, and John Creighton,
Her special license that we, the said William Coare Brocklehurst, Joseph
Creighton, and John Creighton, our executors, administrators, and assigns, or
such others as we, the said William Coare Brocklehurst, Joseph Creighton,
and John Creighton, our executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-

page_text: after 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 "CERTAIN
IMPROVEMENTS IN MACHINERY OR APPARATUS FOR WINDING YARNS OR THREADS,"
upon the condition (amongst others) that we, the said William Coare
Brocklehurst, Joseph Creighton, and John Creighton, our executors or
administrators, by an instrument in writing under our, or one of our, or
their, or one of their hands and seals, 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 John Creighton, 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 and accompanying Drawings (that is to say) :-
Our Invention relates to that description of machinery for winding yarn or
thread called "pin cop winding frames," wherein yarn is wound from the
bobbin "race" or hank on to a wooden pin or spool, which is placed on the
shuttle skewer for weaving. Our improvements are designed to dispense with
such wooden pin or spool, and to wind and form the "cops" on the bare
spindle, which has hitherto been impracticable from a want of apparatus to
"shape" the cop. The improvements consist in an arrangement of apparatus
to effect the shaping of the cop as the yarn or thread is wound on, which is
constituted as follows:-The yarn is wound upon the bare spindle, and
delivered thereto through an eye at the end of one arm of a bell-crank lever,
the other arm of such lever passing through a bowl running in a vertical slot
in a stand, and which receives a reciprocating motion from a cam, crank, or
eccentric; by this means the bell crank is caused to vibrate and to deliver the
yarn to form the cop. The apex or top cone of the cop is surmounted by a
cap, which bears upon it, and which is connected to a bar sliding on guides,
and which is attached to the centre or fulcrum of the aforesaid bell-crank
lever. Thus, when the cop is commencing the cap and bell crank is at its
lowest point, and has its shortest "throw" or "radius" to form the bottom of
the cop, but as the cop increases the cap becomes raised, and also raises the
bell crank, whereby a continually differing throw is obtained, until the afore-
said sliding bar rises sufficiently high to come into contact with the bowl, when
the radius and throw becomes regular to "build" or form the cylindrical

page_text: portion of the cop. This arrangement is applied to each spindle so as to
render them independent of each other in their motion.
In order that the Invention may be better understood and explained in
detail, we have hereunto attached a Sheet of Drawings, made upon a scale of
about three inches to the foot, similar letters of reference being marked upon
corresponding parts of the apparatus.
Fig. 1 represents an end sectional view of the apparatus for winding cops
on skewers instead of spools, the machine being so arranged that cops may
be wound on each side, one side only being shewn, by way of example, as
fitted for winding; Fig. 2 is a front view of the same; and Fig. 3 represents,
about full size, the apparatus for "shaping" the cop and the arrangement for
effecting the stoppage of the spindles as each cop is finished.
In Fig. 1, a, a, is the framing of the machine; b, the driving shaft, which
drives the spindles a' through the gearing c, and gives through the gearing c¹
motion to the cam d, by which the lever e and connecting rod f are moved;
by this means the bell-crank lever 9 is caused to oscillate and to impart a
sliding reciprocating motion by means of the links h to the vertically slotted
stand i. Sliding in this vertical slot is a receiver or bowl k, through which
one end of a bell-crank lever passes, and as the stand i slides to and fro, its
movement causes the bell-crank lever (the fulcrum of which is attached to
the " cap guide") to oscillate, and effects the delivery of the yarn m by the
other arm of the lever on to the "skewer," the yarn being shewn as proceeding
from a broken or imperfect "cop" (instead of from a hank), for which
purpose the apparatus is also applicable. The apex of the cop is surmounted
by the cap n, which presses thereupon, and is connected to a piece o sliding
on the guide p; the fulcrum of the aforesaid lever being attached to this
sliding cap, the throw of the said lever is altered as the cap rises, which is
necessary in the early part of the formation of the cop, but when the cap rises
sufficiently to bring the bar 9 on the lever into contact with the bowl k, the
throw becomes regular, and the cylindrical part of the cop is formed until it is
completed, at which time the apparatus is stopped by the fulcrum support
passing over the latch at the top of the levers (Fig. 3), and so releasing the
weighted levert, which is retained by the catch on the lower end of the
levers; the release of such lever disengages the coupling box u, and throws it
out of action.
Having now described the nature of the said Invention, together with the
method of carrying the same into practical effect, we wish it to be distinctly
understood that we claim the winding and formation of cops of yarn on bare

page_text: spindles or skewers instead of upon "spools," by means of the aforesaid
apparatus for "shaping" the cop, and the general arrangement and com-
bination of the mechanism which has been herein-before described, set forth,
and fully illustrated in the Drawings attached.
In witness whereof, I, the said John Creighton, have hereunto set my
hand and seal, this Twenty-fourth day of May, in the year of our Lord
One thousand eight hundred and sixty-four.
JOHN CREIGHTON. (L.S.)
