Year: 1875

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."
Sealed the 23rd December 1875, and dated the 24th September 1875.
PROVISIONAL SPECIFICATION left by the said Robert Smith at the
Office of the Commissioners of Patents, with his Petition, on
the 24th September 1875.
I, ROBERT SMITH, of Manchester, in the County of Lancaster,
Machinist, do hereby declare the nature of the said Invention for "Im-
PROVEMENTS IN MACHINERY FOR DOUBLING" AND 'WINDING COTTON AND OTHER
YARNS AND THREADS," to be as follows :—
My Invention relates to doubling and winding machines, by means of
which two or more yarns or threads are wound on to each bobbin with.
out being twisted, and having detective apparatus to arrest the revolution
of a-bobbin or spool-on-the-breaking-or-stoppage-of the-supply-of-one
or more of the said yarns or throads, and particularly to the machinery.

page_text: for which Her Majesty's Royal Letters Patent, bearing date the Twenty-
seventh day of October, in the year 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.
The object of my present Invention, in the first place, is to so stop the t
revolution of the taking-up bobbin, as that a greater length of loose
end will be left between the detective wire and the said bobbin,
whereby the piecing of the broken thread is facilitated. This I effect by
causing a lever, to which the detective drops are attached, to come into
contact with tho said bobbin. Space to allow the said lover to act upon
the the bobbin is made by reducing the width of the driving drum or by
driving the said bobbin by means of two drums, or of a drum in two
parts with a space between in which the said lever acts.
A second part of my Invention has for its object to raiso the brake
plate or drag plate from contact with the said taking-up bobbin by the 1
action of mechanism when a thread breaks, the raising of the said brake
plate baving hitherto been effected by the attendant. To effect this I
attach to or form on the said brake plate a projecting arm or finger,
which said finger by the movement of the swinging frame carrying the
bobbin is brought against a fixed stop piece, the finger being thereby
stopped, and the swing frame still moving the brake plate is caused to
move on its centre or hinge until it is out of contact with the bobbin, in
which position it is held until the thread is pieced.
My improvement further consists in mounting the detective lovers on a
rod extending the length of the frame instead of in separate stands, as
has been the practice hitherto. I am thereby enabled more conveniently
to alter the number of folds to each drum or bobbin.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Robert Smith in the Great Seal Patent Office
on the 22nd March 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
SMITH, of Manchester, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fourth day of September, in the
1

page_text: year of our Lord One thousand eight hundred and seventy-five, in
the fortieth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Robert. Smith,. Her
special licence, that I, the said Robert Smith, my executors, admini-
strators, 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 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 YĖ, 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 doubling and winding machinery, by means of
| which two or more yarns or threads are wound on to each bobbin with-
out being twisted, and having detector apparatus to arrest the revolution
of a bobbin or spool on the breaking or stoppage of the supply of one
or more of the said yarns or threads, and particularly to the machinery
for which Her Majesty's Royal Letters Patent, bearing date the Twenty-
seventh day of October, in the year 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.
The object of my present Invention in the first place is to stop the
revolution of the taking-up bobbin as that a greater length of loose
end will be left between the detector wire and the said bobbin, whereby
the piecing of the broken thread is. facilitated. This I effect. by causing
a lever, to which the detective drops are attached to come into contact

page_text: with the said bobbin. Space to allow the said lever to act upon tho
bobbin is made by reducing the width of the driving drum, or by driving
the said bobbin by means of two drums, or of a drum in two parts with
a space between in which the said lever acts.
A second part of my Invention has for its object to raise the brake ¦
plate or drag plate from contact with the said taking-up bobbin by the
action of mechanism when a thread breaks, the raising of the said brako
plate having hitherto been effected by the attendant. To effect this I
attach to or form on the said brake plate a projecting arm or tail picce,
which, by the movement of the swing frame carrying the bobbin, is
brought against a fixed stop piece, the said arm being thereby stopped,
and the swing frame still moving, the brake plate is caused to move on
its centre or hinge until it is out of contact with the bobbin, in which
position it is held until the thread is pieced.
My improvement further consists in mounting the detective levers on 1
a rod extending the length of the frame instead of in separate stands, as
has been the practice hitherto. I am thereby enabled more conveniently
to alter the number of folds to each drum.
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 made to a scale of about one-half
the full size, being marked with letters of reference. Certain parts
which appeared in the Drawings attached to the Specification 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 accompanying
Drawings, in addition to the said letters of reference.
In the accompanying Drawings Figs. 1 and 2 illustrate the first and
second parts of my Invention, the parts for carrying into effect the first
part of the Invention being to some extent differently arranged in the
two Figures.
In the said Figs. A is the aforesaid taking-up bobbin; B is a detector
wire; and C is a detective drop. The drop C is hinged to one end of a
detent lever D, the fulcrum of which is at E. This lever is formed to
engage with a projection on the lever F as in my said former Inventions.
A brake finger G is fixed or formed on a pin which is fitted into a hole
bored at in the lever D. The end of a screw I bears against the said

page_text: In Figs. 1 and 2 the brake plate, to which the second part of my
Invention relates, is seen at o; the said brako plato is hinged to the
frame p, which carries the bobbin A, and is fitted or formed with an
arm or tail piece q, and the said stop picce is formed with a finger which
projects over the frame p, so as to be in position to act upon the arm q t
when the said frame is raised. The stop piece is fixed upon the
shaft 8, upon which the frames p swivel. In the example the said stop
piece is formed with two fingers, for the reason that the Drawings
represent the parts which are on one side of a double machine.
When the lever F is released, the upper end thereof moves forward, 1
and a projection thereon acts on the curved lower side of the frame p,
and raises the said frame, thereby lifting the yarn on the bobbin A out
of contact with the driving drum, as in my former Invention. The
lifting of the frame p brings the arm q into contact with the stop piece,
and the brake plate is thereby raised from the yarn on the bobbin, as 1
seen in Fig. 2.
Fig. 3 illustrates the remaining part of my Invention. The levers P
are mounted upon a continuous rod or shaft R, which extends throughout
the length of the frame, and is sustained by standards t, which are
arranged at distances apart suitable to the strength of the said shaft. 2
The said levers may thus be readily moved and adjusted sideways, and
the number of levers in a set or cluster be varied as required.
Having now fully described and indicated the nature of my said
Invention, and means whereby the same may be carried into effect, I
would in conclusion have it to be understood that I claim,-
2
First. The employment of two driving drums, or of a drum in two
parts, or of a drum reduced in width as compared with the winding
bobbin, in conjunction with a lever formed or fitted to arrest tho motion
of the winding bobbin when acted upon by the ratchet, substantially
as set forth and indicated herein-before and in the accompanying 3
Drawings.
Secondly. Forming or fitting the drag plate with an arm or a tail
pięce, which comes into contact with a fixed stop when the winding
bobbin is lifted on the breakage of a thread, substantially as and for the
purpose set forth and indicated.
Thirdly. Mounting all the detective levers on a continuous rod or
shaft, substantially as and for the purpose set forth and indicated.

as herein-before described and as illustrated in the accompanying
Drawings.
"
In witness whereof, I, the said Robert Smith, have hereunto set
my hand and seal, this Eighteenth day of March, in the year
of our Lord One thousand eight hundred and seventy-six.
