Year: 1875

page_text: LETTERS PATENT to John Pinkerton Kerr, of Paisley, in the County
of Renfrew, North Britain, Manufacturer, for the Invention of
"IMPROVEMENTS IN MACHINERY FOR WINDING SEWING THREAD."
PROVISIONAL SPECIFICATION left by the said John Pinkerton Kerr
at the Office of the Commissioners of Patents, with his Petition,
on the 26th April 1875.
I, JOHN PINKERTON KERK, of Paisley, in the County of Renfrew,
North Britain, Manufacturer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MACHINERY FOR WINDING SEWING THREAD,"
to be as follows, that is to say :-
-
This Invention relates to improved machinery designed more especially
for winding sewing thread, immediately after it has been polished, upon
large bobbins preparatory to its being rewound on spools, but which is
also suitable for winding the thread when in an unpolished or other
condition.

page_text: The improved winding apparatus is placed so that the thread may be
led to it in a continuous manner from the polishing machine, and
comprises two vertical rectangular frames forming with each other in
plan an acute angle which faces the polishing machine. The winding
bobbins are placed horizontally and in several horizontal rows or tiers
one above the other, and are driven by friction wheels, or by bands, or
by toothed gearing.
In a modification in which they are driven by friction wheels, cach
bobbin is placed on a metal spindle having fixed on it near one end a
small pulley fitted with a driving pin to enter the bobbin end, and a
similar loose pulley, but also having a driving pin is put on the other
end after the spindle is entered through the boro of the bobbin. The
pulleys on the bobbin spindle rest on a pair of frictional driving pulleys
fixed on a horizontal revolving shaft, which has also fixed on it pulleys
for driving all the other bobbins in the same row of one frame. The
bobbins are kept in their places by having the projecting ends of their
spindles entered in guide sockets in the frame. The several horizontal
shafts are geared by bevil wheels at their front ends to a pair of vertical
shafts which have worm wheels fixed on their lower ends, and are driven
by worms on a transverse horizontal shaft in gear with a first motion
shaft driven from or in concert with the polishing machine. The threads
are led upon the several bobbins by traverso guides which are upon light
rectangular frames moved in front of the main frames by means of a lover
acted on by the usual traverse motion heart cam.
The threads pass
horizontally to the traverse guides from guide rods fixed at the front of
the machine, there being a guide rod for each horizontal row of bobbins,
and such guide rod being fitted with vertical pins to separate the
individual threads of each row from one another. For these guide rods
reeds may be substituted, or if proferred the threads may be led over a
series of guide pulleys. The threads pass directly from the polishing
machine to the guide rods or their equivalents.
The improved machinery herein-before described is more convenient
and satisfactory in use than machinery hitherto in use for the same
purpose, and has amongst its advantages the important one of admitting
of a very large number of bobbins being arranged and operated on in a
small and convenient space.

filed by the said John Pinkerton Kerr in the Great Seal Patent
Office on the 25th October 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
PINKERTON KERR, of Paisley, in the County of Renfrew, North Britain,
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of April, in the year
of our Lord One thousand cight hundred and seventy-five, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said John Pinkerton Kerr, Her
special licence that I, the said John Pinkerton Kerr, my executors,
administrators, and assigns, or such others as I, the said John Pinkerton
Kerr, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
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 Inven-
tion for "IMPROVEMENTS IN MACHINERY FOR WINDING SEWING THRead,” upon
the condition (amongst others) that I, the said John Pinkerton Kerr,
my executors or administrators, by an instrument in writing under my,
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 Pinkerton Kerr, do hereby
declare the nature of my said Invention, and in what manner the samo
is to be performed, to be particularly described and ascertained in and
by the following statement in writing, reference being had to the
accompanying Drawings, that is to say :-
My said Invention relates to improved machinery designed more
especially for winding sewing thread, immediately after it has been
polished, upon large bobbins preparatory to its being rewound on spools,
but which is also suitable for winding the thread when in an unpolished
or other condition.

page_text: And in order that my said Invention and the manner of performing
the same may be properly understood, I hereunto append a Sheet of
explanatory Drawings to be herein-after referred to, and representing
winding apparatus as made with my improvements, but without the
repetition as in the actual machine of numerous similar parts. In these t
Drawings the same reference numerals are used to mark the same or
like parts wherever they are repeated.
Figure 1 of the Drawings is a plan of my improved apparatus which
is placed so that the thread may be led to it directly and in a continuous
manner from the polishing machine. The apparatus comprises two 1
vertical rectangular frames 1, 2, which are fixed down on the floor in
such positions as to form with each other in plan an acute angle which
faces the polishing machine.
Figure 2 is a side clevation of one of the said frames and is delineated
as at right angles to its general surface; whilst Figure 3 is a side 1
elevation of some of the driving gearing, but delineated, as at right
angles, to the central vertical planc between the two frames 1, 2. The
winding bobbins 3, of which two are shown at the lower right-hand
corner of Figure 2, are placed horizontally and in several horizontal rows
or tiers one above the other, and in the modification delineated are driven 2
by friction wheels 4.
Figure 4 is an enlarged horizontal section; Figuro 5, an enlarged
clevation; and Figure 6, an enlarged vertical section of the parts imme-
diately connected with one of the bobbins 3, which is indicated in these
Figures by dotted lines, and it is to be understood that all the other 2
bobbins are similarly provided for. Each bobbin 3 is placed on a metal
spindle 5 having fixed on it near one end a small pulley 6 with a
driving pin to enter the bobbin end; and a similar pulley 7 which is
loose, but also has a driving pin, is put on the other end after the
spindle 5 is entered through the bore of the bobbin. The pulleys 6, 7, 8
on the bobbin spindle 5 rest on a pair of frictional driving pulleys 4
fixed on a horizontal revolving shaft 8, which has also fixed on it
pulleys (4) for driving all the other bobbins in the same row of one
frame 1 or 2. The bobbins 3 are kept in their places by having the
projecting ends of their holding spindles 5 entered in guide sockets or 8
grooves 9 formed in the vertical frame bars 10.

page_text: Figure 7 is an inside clevation of one of these frame bars 10, showing
the guide sockets or grooves 9 for two bobbins. The upper parts of
these grooves diverge to both sides to admit of the bobbins being entered
from either side of the frame. The frames 1, 2, are formed with vertical
frame bars 10 between each vertical row of bobbins and the next, cach
bar having guide grooves or sockets 9 on both sides of it. The several
horizontal shafts 8 aro geared by bevil wheels 11 at their front onds to a
pair of vertical shafts 12, 13, which have worm wheels 14 fixed on their
lower ends, and are driven by worms 15 on a transverse horizontal
shaft 16 in gear with a first motion shaft 17 driven from or in concert
with the polishing machine. The worms 15 are one right-handed and
the other left-handed, by which the important advantage is obtained
that the end thrusts are opposed and neutralize each other. The motion
is by proference transmitted by a belt between a pair of cones, of which
one 18 is on the first motion shaft 17 of the winding apparatus, and tho
belt is adjusted by hand gear; or it might be by a self-acting screw
motion to vary the relation of the speed to suit the increasing diameters
of tho bobbins as the winding proceeds.
The threads 19, shown in blue lines in Figure 2, are led upon the
several bobbins 3 by transverse guide pulleys 20 which are upon light
rectangular frames 21, 22, moved in front of the main frames 1, 2, by
means of a lever 23 jointed to a bracket 24, and acted on by the usual
traverse motion heart cam 25. This cam 25 is on a short spindle carried
by a bracket 20 and turned by means of a worm wheel 27 driven by a
worm 27 on the vertical shaft 12. The lever 23 is connected to the
traverse frames 21, 22, by adjustable links 28, and is counterweighted to
keep it against the cam 25. The travorso frames 21, 22, which consist
of vertical and horizontal bars are supported by their uppermost and
lowermost horizontal bars which rest and move on guido brackets 29
fixed to the stationary main frames 1, 2. The threads 19 pass hori-
zontally to the several traverse guide pulleys 20 from guide rods 30 fixed
to the vertical bars at the front ends of the frames 21, 22, there being
one such guide rod 30 for each horizontal row of bobbins, and each
guide rod being fitted with vertical pins, as shown in an enlarged view
of one in Figure 8, to separate the individual threads of each row from
one another. For these guide rods 30 reeds may be substituted, or if
preferred the threads 19 may be led over a series of guide pulleys. The
threads 19 pass directly from the polishing machine, the end 31 of
which is shown in Figure 2, to the guide rods 30 or their equivalents.

page_text: The spindles 5 carrying the bobbins 3 may be driven by bands or
cords from drums, or by toothed gearing instead of by the friction
pulleys 4, 6, 7.
My improved machinery herein-before described is more convenient
and satisfactory in use than machinery hitherto employed for the same 5
purpose, and has amongst its advantages the important one of admitting
of a very large number of bobbins being arranged and operated on in a
small and convenient space.
Having thus particularly described my said Invention, and the manner
of performing the same, I have to state that I do not restrict myself to 1
the precise details herein described or delineated, but that what I believe
to bo novel and original and claim as the Invention secured to me by
the herein-before in part recited Letters Patent is,―
1. The arranging and combining together of the parts of apparatus
for winding sewing thread, substantially in the improved manner herein- 1
before described.
2. The arranging of a number of horizontal revolving shafts to drive
horizontally placed bobbins by means of frictional wheels for winding
sewing thread, substantially as heroin-before described.
In witness whereof, I, the said John Pinkerton Kerr, have here- 2
unto set my hand and seal, this Twenty-second day of October,
in the year of our Lord One thousand cight hundred and seventy-
five.
