IMPROVEMENTS IN MACHINERY FOR DOUBLING AND WINDING FIBROUS MATERIALS
Year: 1869

page_text: LETTERS PATENT to Walter McGee and William M.Gee, both of
Paisley, in the County of Renfrew, North Britain, Engineers, for
the Invention of "IMPROVEMENTS IN MACHINERY FOR DOUBLING AND
WINDING FIBROUS MATERIALS."
Sealed the 10th May 1870, and dated the 14th December 1869.
PROVISIONAL SPECIFICATION left by the said Walter McGee and
William McGee at the Office of the Commissioners of Patents, with
their Petition, on the 14th December 1869.
We, WALTER M°GEE and WILLIAM MCGEE, both of Paisley, in the
County of Renfrew, North Britain, Engineers, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN MACHINERY FOR DOUBLING
AND WINDING FIBROUS MATERIALS," to be as follows, that is to say:
This Invention relates to those details of doubling and winding
machinery by which the winding action of any bobbin or spool is

page_text: stopped on the breakage or failure of any one of the threads or yarns of
fibrous material, and it comprises improvements in the arrangement and
combination of the details.
The bobbin or spool, which is by preference driven by the frictional
action of a pulley on which its winding surface rests, is carried by a
pair of swinging arms, which when a thread breaks are raised so as to
lift the bobbin or spool out of driving contact. The arms are raised
by a lever acted upon by a spring or weight, but which is kept out
of action by a catch on another lever or rod. The threads are passed
through eyes in the ends of light guide wires, and when a thread breaks
or fails the corresponding guide wire falls upon a delicately balanced
lever carried by the catch lever or rod, and the balanced lever then turns
a tongue into the way of a wiper or catch fixed on and revolving with
the shaft of the frictional winding pulley. This causes the revolving
catch to act on the catch lever or rod and so release the raising lever,
and the winding is stopped in consequence. The parts are arranged so
as to be easily readjusted when about to recommence winding.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Walter McGee and William McGee in the Great
Seal Patent Office on the 11th June 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WALTER
M°GEE and WILLIAM MCGEE, both of Paisley, in the County of Renfrew,
North Britain, Engineers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of December, in the year
of our Lord One thousand eight hundred and sixty-nine, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Walter McGee and William McGee,
Her special licence that we, the said Walter McGee and William McGee,
our executors, administrators, and assigns, or such others as we, the said
Walter McGee and William McGee, 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

page_text: of Great Britain and Ireland, the Channel Islands, and Isle of Man,
an Invention for "IMPROVEMENTS IN MACHINERY FOR DOUBLING AND WINDING
FIBROUS MATERIALS," upon the condition (amongst others) that we, the
said Walter McGee and William McGee, 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 we, the said Walter McGee and William McGee,
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 in writing, reference being had to the
accompanying Drawings, that is to say :-
Our said Invention relates to those details of doubling and winding
machinery by which the winding action of any bobbin or spool is
stopped on the breakage or failure of any one of the threads or yarns of
fibrous material, and it comprises improvements in the arrangement and
combination of the details.
And in order that our said Invention and the manner of performing
the same may be properly understood, we have hereunto appended an
explanatory Drawing to be herein-after referred to, and representing a
transverse vertical section of a doubling and winding machine as
constructed with our improvements.
The general arrangement of the machine to which our improvements
are applied need not differ materially from that of existing machines
for the same purpose. There are in it two horizontal longitudinal
shafts 1 carrying pulleys 2, by the rotation of which the winding
bobbins 3 are turned and made to draw and wind up the threads
or yarns 4 which are led to them in the usual way from cops or
spindles 5, the threads or yarns being doubled or combined in two's
or three's as is well understood. Each bobbin 3 rests by its winding
surface on the periphery of the pulley 2 so as to be driven in a well-
known mode by frictional contact, but it is also held by a
pair of

page_text: swinging arms 6, which when a thread breaks are raised so as to lift the
bobbin out of driving contact. On the left hand side of the Drawing
the parts are represented as in the positions in which they are when
the winding is proceeding in a proper manner, whilst on the right hand
side they are shown in the positions they assume when a thread breaks,
the swinging arms 6 being in the act of lifting the bobbin 3 out of
driving contact. The swinging arms 6 for both sides are centred on a
rod 7 fixed along the centre of the machine at the top. The arms 6
are in each case raised by a lever 8 centred on a bracket 9 and acted on
by a spring 10 (or it might be by a weight), one of each pair of arms
being formed with an incline on its under side, which is acted on by a.
pin in the lever 8, indicated by a dotted circle. The lever 8 is ordinarily
kept out of action by a catch 11 indicated by dotted lines and which
takes into a notch on the under side of another lever 12, herein-after
termed the catch lever. The threads 4 are passed through eyes in the
ends of light guide wires 13, and when a thread breaks the guide
wire 13 of that thread falls upon the transversely bent end of a delicately
balanced lever 14 suspended at the end of the catch lever 12, and the
balanced lever 14 then turns a tongue 15 into the way of wipers or
catches 16 fixed on and revolving with the shaft 1 of the frictional
driving pulleys 2; this causes the revolving catches 16 to lift the catch
lever 12, as shown on the right-hand side of the Figure, and so release
the raising lever 8, and the winding is stopped in consequence. The
parts are arranged so as to be easily readjusted when about to re-
commence winding. Thus, when the thread guide 13 is held up again
by the thread the balanced lever 14 takes the tongue 15 of the catch
lever 12 out of the way of the revolving catches 16. At the same time
the raising lever 8 is pushed inwards by its upper end prolonged to
serve as a handle, which causes the catch 11 to engage with the catch
lever 12, and allows the swinging arms 6 to lower the bobbin 3 into
driving contact with the pulley 2.
Having thus particularly described our said Invention and the manner
in which the same is to be performed, we have to state that what we
believe to be novel and original, and claim as the Invention secured to
us by the herein-before in part recited Letters Patent is, the arranging
and combining together of those parts of doubling and winding machines
which relate to the stopping of the winding on, the breakage, or failure

page_text: of a thread or yarn, substantially in the improved manner herein-before
described.
In witness whereof, I, the said William McGee, on behalf of the
the said Walter McGee and myself, have hereunto set my hand
and seal, this Tenth day of June, in the year of our Lord One
thousand eight hundred and seventy.
Witness,
EDMUND HUNT,
Patent Agent,
