INPROVEMENTS IN PIN OR PIRN WINDING MACHINES
Year: 1875

page_text: LETTERS PATENT to Joy Robinson, of Little Lever, and Albert
Settle, of Bolton, both in the County of Lancaster, for the Inven-
Sealed the 19th April 1876, and dated the 20th October 1875.
PROVISIONAL SPECIFICATION left by the said Joy Robinson and
Albert Settle at the Office of the Commissioners of Patents, with
their Petition, on the 20th October 1875.
We, JOY ROBINSON, of Little Lever, and ALBERT SETTLE, of Bolton,
both in the County of Lancaster, do hereby declare the nature of the
said Invention for "INPROVEMENTS IN PIN OR PIRN WINDING MACHINES," to
be as follows :—
This Invention relates to those pin or pirn winding machines in which
cach pirn is caused to revolve by the friction of a revolving wheel or
disc, and one arrangement consists in making cach disc of an improved
shape, and so arranging the bearings and other working parts that the
discs will be independent of each other, so that any one can be removed
or changed without interfering with the others.

page_text: We make cach disc in the form of a flat circular plate having a
recessed chamber and central boss, the transverse length of one side
corresponding in length with the length of the conical part of the
pirn, and the recessed chamber occupying the space between the inner
edges.
The bosses are perforated in the centres and grooved in their
peripheries to act as pulleys, and the discs work on independent studs
bolted to cross plates or frames fixed to the cross beams of the machine,
and the cross plates, studs, and wheels are placed at an angle corre-
sponding with the angle or taper of the pirn.
The yarn to be wound on the pirns is supplied to the machine in the
usual manner, and distributed evenly over the taper part of the pirn by
means of the ordinary heart motion, and the friction discs which are
driven by bands running in the grooves of the bosses have the required
variable speeds given to them by any well known means.
In another arrangement instead of the discs before described, we
employ a conical bowl with a wharve at the bottom to which the
driving band is attached. The conical bowl fits on a spindle fastened to
the top stationary rail, and rests against the pirn to which it gives
motion by its friction when driven by the band, and from its conical
form gives the required shape to the cop as it is formed. Or instead of
the conical bowl we use a parallel one placed on an inclined stud fixed
to the rail, the bowl having a wharve for enabling it to be turned by a
band from the driving drum, and for both the conical and parallel bowls
the thread is raised and lowered by the ordinary heart motion.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joy Robinson and Albert Settle in the Great
Scal Patent Office on the 20th April 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, Joy
ROBINSON, of Little Lever, and ALBERT SETTLE, of Bolton, both in the
County of Lancaster, send greeting.

page_text: of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said Joy Robinson and Albert
Settle, Her special license that we, the said Joy Robinson and
Albert Settle, our executors, administrators, and assigns, or such
others as we, the said Joy Robinson and Albert Settle, our exe-
cutors, 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 we, the said Joy Robinson and Albert Settle, our executors or
administrators, by an instrument in writing under 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 wc, the said Joy Robinson and Albert Settle,
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 pin or pirn winding machines in
which each pirn is caused to revolve by the friction of a revolving disc
or wheel, and one arrangement consists in making each disc of an
improved shape, and so arranging the bearings and other working parts
that the discs will be independent of each other, so that any one can
be removed or changed without interfering with the others.
We make each disc in the form of a flat or straight faced circular
plate having a recessed chamber and central boss, the transverse length
of one side corresponding in length with the length of the conical part
of the pirn, and the recessed chamber occupying the space between the
inner edges.
The bosses are perforated in the centres and grooved in their
peripheries to act as pulleys, and the discs work on independent studs
bolted to cross plates or frames fixed to the cross beams of the machine,

page_text: and the cross plates, studs, and discs are placed at an angle corre-
sponding with the angle or taper of the pirn.
The yarn to be wound on the pirns is supplied to the machine in the
usual manner, and distributed evenly over the taper part of the pirn by
means of the ordinary heart motion and the friction discs, which are
driven by bands running in the grooves of the bosses, have the required
variable speeds given to them by any well known means.
In another arrangement instead of the disc before described we
employ a conical bowl with a wharve at the bottom to which the driving
band is attached. The conical bowl fits on a spindle fastened to the
top stationary rail or beam, and rests against the pirn to which it gives
motion by its friction when driven by the band, and from its conical
form gives the required shape the cop as it is formed. Or instead of
the conical bowl we use a parallel one placed on an inclined stud fixed
to the rail, the bowl having a wharve for enabling it to be turned by a
band from the driving drum, and for both the conical and parallel
bowls the yarn is raised and lowered by the ordinary heart motion.
These improvements will be clearly understood by the following
particular desciption thereof, reference being had to the figures and
letters on the accompanying Sheet of Drawings in which Figs. 1 and 21
are end and side elevations of one end of a pin or pirn winding machine
provided with the first-mentioned arrangement of our improvements,
Fig. 3, a detached view of some of the parts; and Figs. 4, 5, 6, and 7
are views representing the other arrangements of our improvements,
Figs. 1, 2, 4, and 5 being drawn to a scale of one and a half inches to
the foot, and Figs. 3, 6, and 7, about full size.
с
In the arrangement shewn in Figs. 1, 2, and 3, the discs marked a,
having recessed chambers b, work on independent studs c bolted to the
cross plates d fixed to the rails or beams e bolted to the end frames ƒ of
the machine, and it will be seen that the cross plates, studs, and discs
are placed at an angle corresponding with the angle or taper of the pirn,
and the discs which are driven by bands encircling the driving drum g,
and the wharves h cast to the discs have the required variable speeds
imparted to them by any well known means. The pirns are fitted loose
on spindles k on which the pirns revolve, the spindles being fixed to
brackets I, one part of which moves up in sockets m fixed to the rails or
beams e, there being a steadying plate n to keep the pirn and yarn close

page_text: Secondly. The conical bowls and parts connected with them for
enabling the pirns with the yarn to rise as the yarn is wound on.
And, Thirdly. The parallel bowl for the same purpose, as all such
improvements are herein described or any mere modification thereof.
In witness whereof, we, the said Joy Robinson and Albert Settle,
have hereunto set our hands and seals, this Eighteenth day
of April, in the year of our Lord One thousand eight hundred
and seventy-six.
JOY ROBINSON.
