IMPROVEMENTS IN MACHINERY FOR DOUBLING AND WINDING COTTON AND OTHER YARNS AND THREADS."
Year: 1874

page_text: LETTERS PATENT to Robert Smith, of Manchester, in the County of
Lancaster, Machinist, for the Invention of "IMPROVEMENTS IN
MACHINERY FOR DOUBLING AND WINDING COTTON AND OTHER YARNS AND
THREADS."
PROVISIONAL SPECIFICATION left by the said Robert Smith at the
Office of the Commissioners of Patents, with his Petition, on the
1st October 1874.
I, ROBERT SMITH, of Manchester, in the County of Lancaster,
Machinist, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY FOR DOUBLING AND WINDING COTTON AND OTHER
YARNS AND THREADS," to be as follows:-
My Invention relates to former Inventions for which Letters Patent
bearing date the Twenty-seventh day of October, One thousand eight
hundred and sixty-three, and the Twenty-eighth day of March, in the

page_text: year One thousand eight hundred and seventy, have been granted
to me.
In the said former Inventions two or more threads or yarns were
wound upon each bobbin or spool without being intertwisted, and the
said Invention comprised arrangements for insuring the stoppage of the
bobbin on the breakage of one of the said threads.
In the Specification of the last-named Invention the ends of yarn
passed through detector eyes and over or around a roller, and thence to
the bobbin.
According to my present Invention I cause the said ends to pass over
or around the said roller on their way to the said detector eyes, that is
to say,
I place the said roller between the cops or spools from off which
the yarn is being wound and the said detector eyes. When so arranged
the broken end is not so liable to reach the winding bobbin before the
rotation of the said bobbin is arrested; and also the said broken end is
not so liable to wrap around the said roller. To arrest the rotation of
the said roller I may employ a lever, which is actuated by the part
which slides forwards on the breakage of an end, as described in the
Specification of the latter of my said former Inventions.
SPECIFICATION in pursuance of the conditions of the Letters Patent, a
filed by the said Robert Smith in the Great Seal Patent Office
on the 12th March 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
SMITH, of Manchester, in the County of Lancaster, Machinist, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
year of
Letters Patent, bearing date the First day of October, in the
our Lord One thousand eight hundred and seventy-four, in the thirty-
ninth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Robert Smith, Her special license.
that I, the said Robert Smith, my executors, administrators, and assigns,
or such others as I, the said Robert Smith, my executors, administrators,
and assigns, should at any time agree with, and no others, from

page_text: 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 MACHINERY
FOR DOUBLING AND WINDING COTTON AND OTHER YARNS AND THREADS," upon the
condition (amongst others) that I, the said Robert Smith, 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 Robert Smith, do hereby declare
the nature of the 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:-
My Invention relates to former Inventions for which Letters Patent
bearing date the Twenty-seventh day of October, One thousand eight
hundred and sixty-three, and the Twenty-eighth day of March, in the
year One thousand eight hundred and seventy, have been granted
to me.
In the said former Inventions two or more threads or yarns were
wound upon each bobbin or spool without being intertwisted, and the
said Invention comprised arrangements for ensuring the stoppage of the
bobbin on the breakage of one of the said threads.
In the Specification of the last-named Invention the ends of yarn
passed through detector eyes and over or around a roller, and thence to
the bobbin.
According to my present Invention I cause the said ends to pass over
or around the said roller on their way to the said detector eyes, that is
to say, I place the said roller between the cops or spools from off which
the yarn is being wound and the said detector eyes. When so arranged.
the broken end is not so liable to reach the winding bobbin before the
rotation of the said bobbin is arrested; and also the said broken end is
not so liable to wrap around the said roller. To arrest the rotation of
the said roller I employ a lever, which is actuated by the part which
slides forwards on the breakage of an end.

page_text: And in order that my said Invention may be fully understood I will
refer in this place to the Drawing which I have caused to accompany
this Specification, the said Drawing being made to a scale of about one-
half the full size and marked with letters of reference.
Certain parts which appeared in the Drawings attached to the Speci-
fication of the Patent granted to me in the year One thousand eight
hundred and seventy, as aforesaid, and which parts were numbered in
such Drawings, have been marked with corresponding numbers in the
sccompanying Drawings, in addition to the said letters of reference.
In the said accompanying Drawing a is the aforesaid roller, is one
of the detector eyes, and c is the bobbin upon which the ends are
wound. Each end of yarn is drawn from the cop d or from the bobbin
or spool which may be substituted therefor, over the curved surface e
to the eye f, thence partly around the roller a to the detector cyc b.
From the said detector eye the said end passes over the rod g and
through the traversing guide ' to the winding bobbin c. The shank of
7'
each detector eye is attached to a parth which is jointed to one end of
the lever i. When an end breaks the corresponding detector cyc falls
to some extent, whereby the part is permitted to approach the
revolving ratchet-shaped roller j, which engages with a projection on the
part and draws down the said said part, whereby the lever i is caused
to raise the lever / which releases the lever 7. A projection on the last-
named lever raises the frame in which the bobbin c is mounted, and
thus stops the winding, as in my former Invention. When the lever
is released and the upper part is caused to move by the action of the
spring m a bar n with which the said lever is connected is moved
forwards in the direction indicated by the arrow. A pin on the said bar
disengages the part / from the teeth of the ratchet j, and a second pin
releases the brake lever o so as to raise the curved end of the said lever
until it presses against the periphery of the roller a. The curved end of 1
the said lever thus acts as a brake to arrest the motion of the roller after
the breakage of an end of yarn.
