Year: 1868

page_text: LETTERS PATENT to James McGhie, of Glasgow, in the County of
Lanark, North Britain, for the Invention of "IMPROVEMENTS IN
APPARATUS FOR SPINNING OR TWISTING."
Sealed the 17th October 1868, and dated the 20th April 1868.
PROVISIONAL SPECIFICATION left by the said James McGhie at
the Office of the Commissioners of Patents, with his Petition, on
the 20th April 1868.
I, JAMES MGHIE, of Glasgow, in the County of Lanark, North
Britain, do hereby declare the nature of the said Invention for "IM-
PROVEMENTS IN APPARATUS FOR SPINNING OR TWISTING," to be as follows, that
is to say:
This Invention has for its objects the improvement and simplification
of apparatus for spinning and twisting; and one improvement consists
in substituting for the ordinary spindle and flyer arrangement a non-
revolving spindle on which the bobbin or pirn rotates, and is moved up
and down by the ordinary or other traverse movement, whilst for, the
flyer there is substituted a kind of inverted flyer or pair of flyer legs..

page_text: fixed to the pulley or pinion or to a disc or plate that is attached to or in
one piece with the pulley or pinion.
In one modification the spindle on which the bobbin or pirn runs
is stationary and may be rigidly fixed, being made partly tubular for
the passage up into it of a wire which communicates the traverse
movement to the bobbin or pirn. The tubular spindle is slotted at
the sides and a pin passed through the slots connects the traverse wire
to the disc on which the bobbin or pirn rests.
In another modification the spindle has the traverse movement
imparted directly to itself.
A second improvement comprised in the Invention consists in
applying to one or to each of the flyer legs a small roller of metal, delf,
glass, or other suitable material for the thread, yarn, sliver, or roving
to pass over, so as to reduce the friction experienced with ordinary flyers.
This improvement is applicable to ordinary flyers as well as to the
improved arrangement herein-before described.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James McGhie in the Great Seal Patent Office.
on the 17th October 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
M°GHIE, of Glasgow, in the County of Lanark, North Britain, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of April, in the year of
our Lord One thousand eight hundred and sixty-eight, in the thirty-
first year of Her reign, did for Herself, Her heirs and successors,
give and grant unto me, the said James M.Ghie, Her special licence
that I, the said James McGhie, my executors, administrators, and
assigns, or such others as I, the said James McGhie, 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.

page_text: APPARATUS FOR SPINNING OR TWISTING," upon the condition (amongst others)
that I, the said James McGhie, 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 James McGhie, 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 in writing, reference being had to the accom-
panying Drawings, that is to say :-
My said Invention has for its objects the improvement and simplifica-
tion of apparatus for spinning and twisting; and in order that my said
Invention and the manner of performing the same may be properly
understood I have hereunto appended a Sheet of explanatory Drawings to
be herein-after referred to, and representing what I consider to be the
best modification of my improved apparatus as arranged for twisting.
Figure 1 is a front elevation of a portion of a twisting frame; and
Figure 2 is a corresponding transverse vertical section; Figure 3 is a
vertical section drawn full size of the details to which my Invention
more particularly relates. The same reference numerals are used to
mark the same or like parts in all the Figures.
In carrying out my Invention I substitute for the ordinary spindle
and flyer arrangement a non-revolving spindle 1, on which the bobbin 2
or pirn rotates and is moved up and down by the ordinary or other
traverse movement. For the ordinary flyer I substitute a kind of
inverted flyer or pair of flyer legs 3 fixed to the pulley 4, when a pulley
such as is shown is used to be driven by a cord or band, or to the bevil
pinion or disc when toothed or frictional gearing is employed. In the
modification represented in the Drawing the spindle 1 is stationary
and partly tubular, being made of brass and fixed by screwing on the
upper end of a short tubular iron or steel spindle or stud 5 which is
fixed by means of a screw nut 6 in the horizontal frame bar 7. The
pulley 4 carrying the flyer legs 3 is fitted to run on the stud 5. The
bobbin 2 rests on a washer 8 fitted to slide easily up and down on the
spindle 1, and a pin 9 is fixed in it and passes across a slot formed in
the spindle 1, whilst a wire 10, fixed to the traverse bar 11 below passes

page_text: up through the tubular stud 5 and communicates the traverse move-
ment to the cross pin 9, and by its means to the washer 8 and bobbin 2.
The pair of threads 12 to be twisted are led down to the bobbins in a
manner that will be easily understood from Figures 1 and 2 passing
from a guide eye 13 directly above the spindle, 1 to one of the flyer
legs 3, and thence to the bobbin 2, the twisting and winding-on actions
being practically the same as with ordinary apparatus. A small roller
or pulley 14 of metal, delf, glass, or other suitable material is mounted
on a pin on the flyer leg 3, and the thread yarn, sliver, or roving passes
round it on its way to the bobbin 2, and in consequence experiences
much less friction than with ordinary flyers. The pulley 14 is shown in
edge view at A and may be applied to ordinary flyers as well as to my
improved arrangement.
The apparatus is shown as arranged for twisting, but it will be
obvious to the practical spinner that the same construction is equally
applicable to apparatus arranged for spinning.
Having thus particularly described my said Invention, and the
manner in which the same is to be performed, I have to state that I do
not restrict myself to the precise details herein described or delineated, but
that what I believe to be novel and original, and claim as the Invention
secured to me by the herein-before in part recited Letters Patent is,-
1. The constructing of apparatus for spinning or twisting with fixed
spindles made tubular and slotted for the communication of the traverse
movement, substantially in the manner herein-before described.
And, 2. The placing of a roller or pulley (14) on the flyer leg to reduce
the friction of the thread or yarn, substantially as herein-before described.
In witness whereof, I, the said James McGhie, have hereunto set
my hand and seal, this Sixteenth day of October, in the year of
our Lord One thousand eight hundred and sixty-eight.
Witness,
EDMUND HUNT,
Patent Agent,
Glasgow.
