Year: 1869

page_text: LETTERS PATENT to George Heyes, of Radcliffe, in the County of
Lancaster, and Edward Barlow, of Little Lever, in the said County,
for the Invention of "IMPROVEMENTS IN MACHINERY FOR WINDING YARNS
OR THREADS ON BOBBINS."
Sealed the 26th October 1869, and dated the 28th April 1869.
PROVISIONAL SPECIFICATION left by the said George Heyes and
Edward Barlow at the Office of the Commissioners of Patents, with
their Petition, on the 28th April 1869.
We, GEORGE HEYES, of Radcliffe, in the County of Lancaster, and
EDWARD BARLOW, of Little Lever, in the said County, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN MACHINERY FOR
WINDING YARNS OR THREADS ON BOBBINS," to be as follows:-
This Invention relates to those machines having conical bobbins or
pirns, and consists in improved arrangements of mechanism for enabling

page_text: the yarn to be taken off the reels and wound on the bobbins at a uniform
speed. The spindles of the bobbins are connected by bands to the tin
drum in the usual manner, but instead of giving the drum an uniform
speed as at present we give it a continually varying speed according to
the varying diameters of the parts of the bobbins where the yarn is
received. On the driving shaft of the machine we fix a pinion, and gear
it into a toothed wheel fixed to a shaft carrying an eccentric wheel
geared into another eccentric wheel, on the shaft of which there is a
toothed wheel gearing into a pinion on a shaft having a pulley connected
by a band to a pulley fixed to the shaft of the tin drum, or we fix the
last-mentioned pinion to the drum shaft direct. The eccentric wheels
are arranged to make one entire revolution for one up-and-down move-
ment of the traversing guide, the wheels causing the tin drum to turn
faster and slower according to the position of the yarn on the conical
bobbins, which bobbins lose speed when the yarn is on the larger
diameter and gain it when on the smaller. During one-half of the
revolution of the eccentric wheels the bobbins are gradually increasing
in speed and for the other half decreasing in speed, the traversing guide
following the same motions, and thus the yarn is drawn off the reels and
wound on the bobbin at a uniform speed.
We do not confine ourselves to the arrangement of gearing between
the tin drum and driving shaft as before described, but use, when desired,
worms and worm wheels, or chain wheels driven, by chains in connection
with the eccentric wheels.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Heyes and Edward Barlow in the Great
Seal Patent Office on the 28th October; 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GEORGE
HEYES, of Radcliffe, in the County of Lancaster, and EDWARD BARLOW,
of Little Lever, in the said County, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of April, 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,

page_text: give and grant unto us, the said George Heyes and Edward Barlow,
Her special license that we, the said George Heyes and Edward Barlow,
our executors, administrators, and assigns, or such others as we, the said
George Heyes and Edward Barlow, our 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, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVEMENTS IN MACHINERY FOR WINDING YARNS
OB THREADS ON ВOBBINS," upon the condition (amongst others) that we,
the said George Heyes and Edward Barlow, our executors or adminis-
trators, by an instrument in writing under our, or their, or one of our
or 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 we, the said George Heyes and Edward Barlow,
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 (that is to say):-
This Invention relates to those winding machines having conical-
headed bobbins or pirns, and consists in improved arrangements of
mechanism for enabling the yarns to be wound on the bobbins or pirns
at a uniform speed, and placed regularly side by side. The spindles of
the bobbins are driven by bands on the tin drum in the usual manner,
but instead of giving the drum a uniform speed as at present we give it
a continually varying speed according to the varying diameters of the
parts of the bobbins where the yarn is received, and the heart wheel for
working the traversing guides has a varying speed corresponding with
that of the tin drum.
The manner in which our Invention is to Be performed will be clearly
understood by the following particular description thereof, reference
being had to the Figures on the accompanying Sheet of Drawings, and
to the letters of reference marked thereon.
Figures 1 and 2 are front and end elevations of one end of a winding
machine provided with one arrangement of our improvements; Figure 3,

page_text: a front view of a different arrangement of the gearing and eccentric
wheels; and Figures 4 and 5 are views representing other arrangements
of eccentric gearing for obtaining a varying motion.
In Figures 1 and 2, a, b, represent the framework at one end of the
machine; c, part of the bearing or cross rails; d, the driving shaft;
e, the driving pulley; f, some of the bobbins on which the yarns or
threads are wound; g, the traversing guides; h, the tin drum; i, the tin
drum shaft; and 1, snugs or projections cast or fixed to one end of the
tin drum. On the driving shaft d we fix a pinion and gear it into a
toothed wheel fixed to the shaft m carrying an eccentric wheel n
geared into another eccentric wheel o on the shaft p, to which shaft is
fixed the toothed wheel q and the heart wheel 7. The toothed wheel
gears into a cavity pinion s cast or fixed to a hollow spindle t working
in a bearing u fixed to the end frame a, and carrying at one end the
driver or projection v, which, when the machine is at work acts on the
snug j, and gives revolving motion to the tin drum, there being pieces
of leather, india-rubber, or other suitable material between the driver and
the snugs to prevent noise. The eccentric wheels n, o, are arranged to
make an entire revolution for one up-and-down movement of the
traversing guides, the wheels causing the tin drum to turn faster or slower
according to the position of the yarn on the conical-headed bobbins f,
which bobbins lose speed when the yarn is winding on the larger diameter
and regain it when winding on the smaller diameter. During one-half
of the revolution of the eccentric wheel the bobbins are gradually
increasing in speed and for the other half decreasing in speed, the
traversing guides following the same motions, and thus the yarns are
drawn off the hanks w and wound on the bobbins at a uniform speed.
The traversing guides g are required to rise and fall simultaneously at
varying speeds corresponding with the speed of the tin drum, and to
attain this object the heart wheel must be fixed on the shaft p, where
the varying motion is acquired, and, when desired, we employ a grooved
heart wheel or other ordinary traversing motion. We also, when desired,
dispense with the cavity pinion and fix a pinion on a short shaft in line
with the tin drum shaft, the pinion and the large wheel by which it is
driven being outside the end frame a; this arrangement is shewn in.
Figure 3, in which represents the pinion geared into the large wheel q
on the shaft p of the eccentric wheel o, which gears into the eccentric

page_text: wheel n, driven by the wheel 1, pinion, and driving pulley e, as in
Figures 1 and 2. The pinion is fixed to the short shaft y, having a
catch or projection z in contact with a catch or projection a' on the tin
drum shaft i, and the catches are covered with leather, india-rubber, or
other suitable material to prevent noise when the machine is at work, and
the tin drum turned by means of the catches.
We do not confine ourselves to the arrangements before described, but
use, when desired, a single eccentric crown wheel fixed to a concentric
spur wheel, and driven by a pinion having teeth sufficiently long to gear
with the teeth as the wheel revolves and changes its radius, as shewn in
Figure 4, or we use a worm geared into an eccentric worm wheel so
formed that at the smallest radius the sides of the teeth gear into the
worm as spur gearing, but as the radius increases to the half of the
wheel the worm gears into teeth, gradually changing from the spur to
the form of the crown wheel, and then receding to the side teeth, as
shewn in Figure 5. In another arrangement we use chain wheels driven
by toothed chains in connection with the eccentric wheels, and, when
desired, we fix a pulley on the tin drum shaft and another pulley on the
last driven shaft for turning the tin drum.
It will be seen that our Invention mainly consists in improved arrange-
ments of the positions of the eccentric gearing and heart wheel, in which
the varying speed of the eccentric wheel o, Figure 1, 2, and 3, and shaft p
shall be transmitted direct to the heart wheel r, and by spur gearing q, s,
to the tin drum h for the purpose of enabling yarns or threads to be wound
on the bobbins at a uniform speed, and building up the bobbins correctly
in consequence of the winding on and traversing motions being exactly
in the same ratio and perfectly agreeing with each other, and the same
result takes place when the heart wheel is fixed to the shaft c', Figure 4,
carrying the eccentric wheel d' worked by the pinion e', and also when
the heart wheel is fixed to the shaft f', Figure 5, carrying the compound
spur and crown wheel g, worked by the worm h.
Having now described the nature and particulars of our said Invention,
and the manner in which the same is to be performed, we desire it to
be understood that in machinery for winding yarns or threads we claim,
the improved arrangements of the positions of the eccentric gearing and
heart wheel for enabling the yarns or threads to be wound on the
bobbins at a uniform speed and building up the bobbins correctly, as all

page_text: such improvements are herein described and illustrated in the accom-
panying Sheet of Drawings.
In witness whereof, I, the said George Heyes, for and on behalf of
myself and the said Edward Barlow, have hereunto set my hand
and seal, this Twenty-seventh day of October, in the year of
our Lord One thousand eight hundred and sixty-nine.
Signed, sealed, and delivered by the
within-named George Heyes, in
the presence of
