PROVISIONAL SPECIFICATION left by the said Henry Bernoulli Barlow
at the Office of the Commissioners of Patents, with his Petition, on the
10th August 1867.
I, HENRY BERNOULLI BARLOW, of the City of Manchester, Patent Agent,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
DOUBLING AND WINDING MACHINES," a communication to me from abroad by
John Dollfus-Mieg, of the Firm of Messieurs Dollfus-Mieg and Company, of
Mulhouse and Dornach, in the Empire of France, to be as follows:-
This Invention is applicable to machines for doubling and winding two or
more yarns or threads of cotton, silk, or other fibrous substances on to a
bobbin or spool without being twisted together. The bobbins on which the
doubled yarns are wound are turned round by the friction of rollers covered
with cloth or other suitable substance. The axles of the bobbins take in slots
in a sliding frame, through which passes a shaft supporting the tumbler levers,
which are held up by the single yarns. The yarn is distributed on the bobbin
by a traversing guide. Above the tumbler levers is a plate to guide the yarns
to be doubled, and below the sliding frame supporting the bobbins is an angle

page_text: piece, which is traversed to and fro by an eccentric or other equivalent.. Both
the sliding frame and the angle piece rest upon brackets with inclines fixed to
the framing of the machine. When the machine is at work the bobbin rests
upon the friction roller, the tumbler levers are held up by the yarns, and the
angle piece traverses to and fro uninterruptedly, but as soon as a single yarn
breaks the tumbler lever held up by it drops, and the catch piece in traversing
carries with it the frame supporting the bobbin; this brings the flanges of the
bobbin against a stop piece, which raises the body of the bobbin out of contact
with the friction roller, thereby preventing any more yarn being unwound,
and as the catch piece continues its traverse the axle of the bobbin runs up
the inclines on the supporting brackets, and lifts the bobbin into a convenient
position for piecing up the broken end. The tumbler levers can all be raised
by means of a lever with a sliding weight; this lever passes through a slot
in a fixed cross rail. By this means the moment a yarn or thread breaks the
bobbin is stopped, and consequently waste is avoided.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Bernoulli Barlow in the Great Seal Patent Office on
the 10th February, 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
"BERNOULLI BARLOW, of. the City of Manchester, Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters

the said Henry Bernoulli Barlow, 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 "IMPROVE-
MENTS IN DOUBLING, AND WINDING MACHINES," a communication to me, from
abroad by John Dollfus-Mièg, of the Firm of Messieurs. Dollfus-Mièg and
Company, of Mulhouse and Dornach, in the Empire of France, upon the
condition (amongst others) that I, the said Henry Bernoulli Barlow, my
executors or administrators, by an instrument in writing under my, or their,

page_text: 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 Henry Bernoulli Barlow, 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 (that is to say):
This Invention relates to that kind of doubling machines in which several
threads are wound together on a bobbin, and in which a single common appa-
ratus stops separately each bobbin when one of the threads breaks or presents
an interruption. Two systems have hitherto been used to stop the bobbin.
In the first a piece supported by the thread falls over when the latter breaks,,
and acts by its weight on a piece or a collection of pieces thereby stopping the
rotation of the bobbin. In the second system a special apparatus is used to..
stop the bobbin at the moment when the instrument supported by the thread:
falls over. The machine forming the subject of this Patent belongs to the
latter system.
The machine is composed of drums giving motion to the winding-on bobbins,..
and of an instrument constantly kept in motion used for the stoppage of the
bobbin at the moment when one part of the improved stop motion described
hereafter comes into operation. On two brackets rests a piece called a slide that
supports the winding-on bobbin, several balanced catches, and an apparatus to
lift them.. The threads pass through wire guides fixed on these catches, and
then are led by a to-and-fro motion, and wound on the bobbin. Beneath the
balanced catches is a flat side bar, which. moves to and fro in a direct straight
line. When a thread breaks, or presents an interruption the balanced catch
which it supported falls over, and is carried by the flat bar to the end of, its
traverse, consequently this catch carries along with it the slide that supports
the bobbin, and by a special arrangement which we shall describe hereafter,
this transferring motion stops the rotation of the bobbin, and then sets, it at
liberty again. For this purpose the slide causes the bobbin to come in contact
with the bracket, thus stopping its winding motion,, and lifts it up. At the
5 end of the stroke an inclined part of the bracket raises both extremities of the
spindle of the bobbin, and thus allows the bobbin to turn. freely. The axis
round which the balanced catches can oscillate bears at the inside of the slide
a. piece called a "lifter on which these catches rest when they have fallen,
and which is used to lift them at the moment when the attendant passes the

page_text: threads through them. For this purpose this axis bears on the outside of the
slide a little lever on which a balance weight can slide; this weight is so
regulated that by moving it from the axis the lifter assumes its upper position
in which the balanced catches are completely raised, and when it again
approaches the axis the catches are in equilibrium. When the slide is in
action the balance weight kept back by a kind of fork being part of the
bracket slides along the lever, and as soon as the motion is accomplished the
catches are again raised by its action. The balanced catches are strongly made,
and fixed on metal tubes. One of the extremities is provided with a hook
surmounted by a wire guide; the other extremity has a screw and nut. This
arrangement allows the pressure on the thread to be regulated by these means,
first, the little wire levers generally used are dispensed with, and strong
pieces are substituted in their stead, thus an extreme sensibility is joined to.
the greatest solidity; secondly, the taking asunder and cleaning are very easy
since the slide rests merely on a bracket, and by unscrewing a screw nut the
-different pieces of the stop.motion may be taken off; thirdly, the simplification of
the attendant's work obtained by the general disposition of the machine, and
particularly because the lifting up of the balanced catches is self-acting, and
because the attendant-is-not obliged-to-displace-the-bobbin to look-for-the-ends-
of the threads.
And in order that the Invention may be better understood I will proceed to
describe the accompanying Drawing of a-bobbin with all its different parts.

Figure 1 is an elevation, partly in section, and Figure 2 is a plan.
A is the stop piece, being part of the bracket S, against which the flange
of the winding-on bobbin B strikes; this bobbin is supported on a spindle B¹;
C, C, are the balanced catches vibrating around the axis L, on which are
fixed the levers L, L"; these catches are provided with wire guides Q, and
are balanced by the nuts C. F is a fork with a to-and-fro. motion to guide
the threads on the bobbin ; G is the thread bearer, serving both as: a con-
necting piece and upper stop piece for the balanced catches; L, the extremity
of the system of levers L, L, L; on this. part L slides a counterweight R,
which being moved from the axis L¹ raises the lifter L". On this latter thei
balanced catches rest when they are no longer supported by the threads;
E is fixed on L by means of the screw V; P, P, slide formed by two pieces.
united by the connecting pieces E and G; S, the bracket on which is cast.
the stop piece A, the inclined plane X, X¹, and on which rest the slide and
the flat bar W; T, the drum giving motion to the bobbin B by contact.or
friction; W is a flat slide-bar moved to and fro in a direct straight line; this
slide bar causes the slide to advance when a balanced catch happens to fall.

page_text: The position of the different parts of the system during the work is shewn
at the right-hand side in Figure 1.
When a thread has just been broken, and the slide is in motion, it assumes
the position shewn at the left-hand side of Figure 1.
When piecing-up takes place the position is shewn by the red lines at the
left-hand side, and when the bobbin is set in motion again the parts are in
the position shewn by the red lines at the right-hand side.
Having thus described the Invention communicated to me by the said John
Dollfus-Mieg, I declare that I claim as my improvements in machines for
doubling cotton yarns and other fibrous materials all the particular and general
arrangements of the machine, and especially the use of a single instrument,
which bearing both bobbin and stop motion places them at the same time out
of the reach of the moving power when a thread breaks.
Also, the means of stopping the bobbin with a single motion, which stops
the rotation of the bobbin instantly, and allows the bobbin to be moved round
at liberty on its axis when this motion is at the end of its course.
Also, the self-acting arrangement of parts above described, or any equivalent
system of lifting the bobbins and disengaging the balanced catches, to place
them more within the reach of the attendant.
Also, the particular arrangement of a piece serving at once as bracket for
the various parts, as a stop piece for the bobbin, and stop piece for the counter-
weight of the self-acting lifter, and as inclined plane to isolate the bobbin at
the end of the motion which causes its rotation to stop.
In witness whereof, I, the said Henry Bernoulli Barlow, have hereto
set my hand and seal, this Eighth day of February, One thousand
eight hundred and sixty-eight.
