Year: 1873

page_text: LETTERS PATENT to Edward Booth, of Manchester, in the County
of Lancaster, Manufacturer, for the Invention of "IMPROVEMENTS IN
PIN OR PIRN WINDING MACHINES.”
Sealed the 29th August 1873, and dated the 20th March 1873.
PROVISIONAL SPECIFICATION left by the said Edward Booth at
the Office of the Commissioners of Patents, with his Petition, on
the 20th March 1873.
I, EDWARD BOOTH, of Manchester, in the County of Lancaster,
Manufacturer, do hereby declare the nature of the said Invention for
** IMPROVEMENTS IN PIN OR PIRN WINDING MACHINES, to be as follows:-
In pin or pirn winding machines of the ordinary construction the yarn
is wound on the pirn in a conical cup. This is objectionable on account
of the friction, and my Invention consists in dispensing with the cups,
and causing the conical end of the pirn to bear against a disc with a
bevelled face. The pirn is loose on a dead spindle, and rises as the yarn
accumulates upon it, the rising of the pirn being facilitated by placing
the axis of the spindle a little to one side of the axis of the disc. The
t

page_text: discs are mounted on a horizontal shaft which is driven by a friction
plate and pulley, or or otherwise, so as to give a variable specd to the pirn,
the speed being quickest when the yarn is being wound on the small
I
diameter of the cone, and slowest when on the large end of the cone.
propose to use two rows of spindles, and in order to save space the discs
of one row are placed so as to pass between the discs of the other row;
the shafts on which the discs are fixed are connected by toothed wheels.
Another part of my Invention is applicable to pirn winding machines
of the ordinary construction, and it consists in fitting a loose bush with
a slot in it into the boss of the wharve for driving the spindle instead of
fixing the slot piece to the said boss as now customary.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said Edward Booth in the Great Seal Patent Office
on the 19th September 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD 1
BOOTH, of Manchester, in the County of Lancaster, Manufacturer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters

Patent, bearing date the Twentieth day of March, in the of our Lord
One thousand eight hundred and seventy-three, in the thirty-sixth year 2
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Edward Booth, Her special licence that I, the said
Edward Booth, my executors, administrators, and assigns, or such
others as I, the said Edward Booth, 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, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle of
Man, an Invention for " IMPROVEMENTS IN PIN OR PIRN WINDING MACHINES,"
upon the condition (amongst others) that I, the said Edward Booth, my 3
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

sists in dispensing with the cups, and causing the conical end of the pirn
to bear against a disc with a bevelled face, the pirn is loose on a dead
spindle, and rises as the yarn accumulates upon it, the rising of the pirn
being facilitated by placing the axis of the spindle a little to one side of
the axis of the disc. The discs are mounted on a horizontal shaft which
is driven by a friction plate and pulley, or otherwise, so as to give a
variable speed to the pirn, the speed being quickest when the yarn is
being wound on the small diameter of the cone, and slowest when on the
large end of the cone.
Another part of my Invention is applicable to pirn winding machines
of the ordinary construction, and it consists in fitting a loose bush with
a slot in it into the boss of the wharve for driving the spindle, instead of
fixing the slot piece to the said boss as now customary.
And in order that my Invention may be fully understood, and readily
carried into operation, I will proceed to describe the accompanying Sheet
of Drawings, in which Fig. 1 is an end view of a pin or pirn winding
machine constructed according to my improvements; Fig. 2 is a side
viow, and Fig. 3 is a transverse section of part of the same; Figs. 4, 5,
and 6 arc detached parts of the machine drawn full size.
a are the end frames which are connected by the beams b, b; c, c, are
the horizontal shafts to which are fixed the discs d, d. One face of each
disc is bevelled to correspond with the taper of the ordinary pirns c.
Each pirn is mounted on a dead spindle f, shewn best in Fig. 5, fixed in
the arm g which projects from the column h, and this column is at
liberty to rise and fall in the socket i fixed to the beam b. To each
socket is fixed an adjustable plate ¹, the object of which is to steady
the pirn while the yarn is being wound on it, and to support the end of
the pirn when full. The yarn is wound on the pirn by the friction of

page_text: the disc d, the bevelled face of which is provided with rings of vulcanized
india-rubber or other suitable material, and the rising of the pirn as
the
yarn accumulates thereon is facilitated by placing the axis of the
pirn a little to one side of the axis of the disc, as shewn best in Fig. 3.
The yarn to be wound on the pirns is supplied to the machine on the
ordinary swifts j, j, and it is distributed evenly over the taper part of
the pirn by the usual heart k, which acts on the levers 7 fixed on the
shafts m, on which are also fixed the arms n for the guide wire. The
heart is driven from one of the shafts c by the train of wheels and
pinions shewn in Fig. 1. The shafts c, c, are driven at variable speeds,
so as to increase the speed of the pirns when the yarn is being wound on
the small diameter of the cone, and to reduce it in proportion to the
increasing diameter of the cone by means of the friction plates o¹ on the
driving shaft o, on which are the fast and loose pulleys o³ and o³. Tho
friction plates give motion to the discs c¹ on the shafts c, and these discs
are moved to and fro over the face of the plates o¹ by means of the
grooved cam k¹ fixed to the heart k and the levers p, in which are studs
taking into the said grooved cam, and in the upper ends of which are
fitted the curved keys taking into grooves in the bosses of the disc c¹.
When the machine is at work the yarn is wound in conical layers on
the pirns e by the friction of the discs d, the yarn being distributed on
the pirns by the guide wires supported by the levers n, and as the yarn
accumulates on the pirns they gradually rise, the columns h rising in
the sockets i, and when the pirns are full the lower end catches on the
plate. The column h is then removed from the machine, the full pirn
is taken off the dead spindle fand an empty one put in its place. The
column h is then dropped in its socket i until the conical part of the pirn
fits on the bevelled face of the disc d, the yarn is then pieced to the
pirn, and the winding then goes on uninterruptedly until the pirn is
again filled.
r
Figs. 7 and 8 represent a transverse section and plan of part of an
ordinary pin or pirn winding machine to which my improvements are
applied. q is the usual socket fixed in the top rail, and is the wharve
fitting on the same. In ordinary winding machines the slot piece is
fixed in the boss of the wharve, but I now propose to fit the loose bush &
into the boss; this bush has a slot in it through which passes the
ordinary flat end of the spindle of the pirn. As the pirn is turned round
in the cup, and the yarn accumulates thereon, it gradually raises the loose

page_text: 8
bush s into the position shewn in Fig. 7, and when the pirn is full the
end of the flat spindle is drawn out of the loose bush, which then drops
on to the end of the socket q, thus leaving the end of the spindle per-
fectly free. By this arrangement the wharve is not liable to be lifted
up by the binding of the flat spindle in the fixed bush as now customary,
and friction is avoided. The wharve and the loose bush may be made
of iron, steel, glass, or earthenware.
Having thus stated the nature of my Invention, and described the
manner of performing the same, I wish to remark that I do not intend
to limit myself to the details given, as they can be considerably varied
or modified, and I declare that I claim,-
First. The improved mode of constructing pin or pirn winding
machines as shewn and described, and particularly the discs with
bevelled surfaces for winding the yarn on the pirns.
And, Secondly. The application of a movable bush with slot to the
wharves of ordinary pin or pirn winding machines, as shewn and
described.
In witness whereof, I, the said Edward Booth, have hereto set my
hand and seal, this Seventeenth day of September One thousand
eight hundred and seventy-three.

In the Matter of the Letters Patent granted to EDWARD BOOTH, of Man-
chester, in the County of Lancaster, Manufacturer, for "IMPROVEMENTS
IN PIN OR PIRN WINDING MACHINES," bearing date the Twentieth day
of March, in the year One thousand eight hundred and seventy three.
DISCLAIMER AND MEMORANDUM OF ALTERATION proposed to be filed
in the Great Seal Patent Office by the said Edward Booth, pursuant to the
Statutes in that case made and provided.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, Edward Booth,
send greeting:
WHEREAS the object of the first part of the Invention for which the said
Letters Patent have been granted to me is to enable me to dispense with the cups
ordinarily employed, and to cause the conical end of the pirn to bear against a disc
formed with a bevelled face. The pirn is loose on a dead spindle, and rises as the
yarn accumulates upon it, the rising of the pirn being facilitated by placing the
axis of the spindle a little to one side of the axis of the disc. The discs are mounted
on a horizontal shaft, which is driven by a friction plate and pulley. Two rows of
spindles are employed, and in order to save space the discs of one row are placed so
as to pass between the discs of the other row; the shafts on which the discs are
fixed are connected by toothed wheels. The object of the second part of the Invention
consists in fitting a loose bush with a slot in it into the boss of the wharve for
driving the spindle:
And whereas the Specification filed in fulfilment of one of the conditions contained
in the said Letters Patent described and claimed the employment of discs with
bevelled surfaces in carrying out the first part of the said objects:
And whereas when carrying my said Invention into effect I only make use of the
said discs when arranged and acting substantially in the manner indicated, and do
not now consider the disc of itself to be novel:

page_text: I desire, in order to render my claims more distinct, and to prevent disputes in
respect thereof, to confine myself to the novel arrangement of the discs I use, that
is to say, to the arrangement described and illustrated when referring to Figures 1 to
6, both inclusive, of the two Sheets of Drawings accompanying my said
Specification.
To this end I propose to strike out and disclaim certain parts of my said Specifi-
cation, and to make the herein after indicated alterations, reference being made to
the Queen's Printers' printed copies thereof, published at the Great Seal Patent
Office in the year One thousand eight hundred and seventy three. In page 3,
line 6, I add the words "and accompanying Drawings," after the word "statement,"
and in the same page, and in line 24, I add the letter "8" to the word "Sheet ;*

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD BOOTH,
of Manchester, in the County of Lancaster, Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters Patent
bearing date the Twentieth day of March, One thousand eight hundred and seventy
three, in the thirty sixth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Edward Booth, Her especial licence
that I, the said Edward Booth, my executors, administrators, and assigns, or such
others as I, the said Edward Booth, my executors, administrators, and assigns
should at any time agree with, and no others, from time to time and at all

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 PIN OR PIRN WINDING MACHINES," upon the condition (amongst others) that I,
'the said Edward Booth, 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 Edward Booth, 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 and
accompanying Drawings (that is to say) :-
In pin or pirn winding machines of the ordinary construction the yarn is wound
on the pirn in a conical cup; this is objectionable on account of the friction and for
other causes. Now my Invention consists in dispensing with the cups, and causing
the conical end of the pirn to bear against a disc with a bevelled face. The pirn is
loose on a dead spindle, and rises as the yarn accumulates upon it, the rising of the
yarn being facilitated by placing the axis of the spindle a little on one side of the
axis of the disc. The discs are mounted on a horizontal shaft, which is driven by a
friction plate and pulley, or otherwise, so as to give a variable speed to the pirn, the
speed being quickest when the yarn is being wound on the small diameter of the

page_text: cone, and slowest when on the large end of the cone. Another part of my Invention
is applicable to pirn winding machines of the ordinary construction, and it consists
in fitting a loose bush with a alot in it into the boss of the wharve for driving the
spindle, instead of fixing the slot piece to the said boss, as now customary.
And in order that my Invention may be fully understood and readily carried into
operation, I will proceed to describe the accompanying Sheets of Drawings, in which
Fig. 1, Sheet 1, is an end view of a pin or pirn winding machine constructed
according to my improvements; Fig. 2 is a side view, and Fig. 3 is a transverse
section of part of the same; Figs. 4, 5, and 6, Sheet 2, are detached parts of the
machine drawn full size.
a are the end frames, which are connected by the beams 6, b; c, c, are the hori-
zontal shafts, to which are fixed the discs d, d. One face of each disc is bevelled to
correspond with the taper of the ordinary pirns e. Each pirn is mounted on a dead
spindle f, shewn best in Fig. 5, fixed in the arm g, which projects from the column h,
and this column is at liberty to rise and fall in the socket i, fixed to the beam b.
To each socket i is fixed an adjustable plate 2, the object of which is to steady the
pirn while the yarn is being wound on it, and to support the end of the pirn when
full. The yarn is wound on the pirn by the friction of the disc d, the bevelled face
of which is provided with rings of vulcanized.india rnbber or other suitable
material, and the rising of the pirn as the yarn accumulates thereon is facilitated
by placing the axis of the pirn a little to one side of the axis of the disc, as shown
best in Fig. 3. The yarn to be wound on the pirns is supplied to the machine on
the ordinary swifts j, j, and it is distributed evenly over the taper part of the pirn
by the usual heart k, which acts on the levers 7 fixed on the shafts m, on which are
also fixed the arms n for the guide wire. The heart k is driven from one of the
shafts c by the train of wheels and pinions shewn in Fig. 1. The shafts c, c, are
driven at variable speeds, so as to increase the speed of the pirns when the yarn is
being wound on the small diameter of the cone, and to reduce it in proportion to
the increasing diameter of the cone by means of the friction plates o' on the
driving shaft o, on which are the fast and loose pulleys o² and o³. The friction
plates give motion to the discs c¹ on the shafts c, and these discs are moved to and
fro over the face of the plates o¹ by means of the grooved cam k¹ fixed to the
heart k and the levers p, in which are studs taking into the said grooved cam, and
in the upper ends of which are fitted the curved keys taking into grooves in the
bosses of the disc c¹. When the machine is at work the yarn is wound in conical
layers on the pirns by the friction of the discs d, the yarn being distributed on
the pirns by the guide wires supported by the levers n, and as the yarn accumulates
on the pirns they gradually rise, the columns h rising in the sockets i, and when
the pirns are full the lower end catches on the plate ¹. The column h is then
removed from the machine, the full pirn is taken off the dead spindle f, and an
empty one put in its place. The column h is then dropped in its socket i until the
conical part of the pirn fits on the bevelled face of the disc d; the yarn is then
pieced to the pirn, and the winding then goes on uninterruptedly until the pirn is
again filled.
Figs. 7 and 8, Sheet 2, represent a transverse section and plan of part of an
ordinary pin or pirn winding machine to which my improvements are applied.
q is the usual socket fixed in the top rail, and r is the wharve fitting on the same.
In ordinary winding machines the slot piece is fixed in the boss of the wharve,
but I now propose to fit the loose bush 8 into the boss. This bush has a slot in it,
through which passes the ordinary flat end of the spindle of the pirn. As the pirn
is turned round in the cup, and the yarn accumulates thereon, it gradually raises
the loose bush 8 into the position shewn in Fig. 7, and when the pirn is full the
end of the flat spindle is drawn out of the loose bush, which then drops on to the
end of the socket q, thus leaving the end of the spindle perfectly free. By this
arrangement the wharver is not liable to be lifted up by the binding of the flat
spindle in the fixed bush as now customary, and friction is avoided. The wharve
and the loose bush may be made of iron, steel, glass, or earthenware.

page_text: Having thus stated the nature of my Invention and described the manner of
performing the same, I wish to remark that I do not intend to limit myself to the
details given, as they can be considerably varied or modified, and I declare that I
claim,―
First. The improved mode of constructing and arrangement of pin or pirn winding
machines, as shewn and described herein with reference to Figs. 1 to 6 of the
accompanying Sheets of Drawings.
And, Secondly. The application of a moveable bush with slot to the wharves of
ordinary pin or pirn winding machines, as shewn and described.
In witness whereof, I, the said Edward Booth, have hereunto set my hand
and seal, this Eleventh day of December, in the year of our Lord One
thousand eight hundred and seventy nine.
