Buildings, Chancery Lane, in the County of Middlesex, Patent
Agent, for the Invention of "A NEW OR IMPROVED STOPPING MOTION POR
SPINNING MACHINERY."-A communication from abroad by Amand
Boutemy, Spinner, of Lannoy, Nord, in the Empire of France.
Sealed the 24th November 1868, and dated the 5th June 1868.
PROVISIONAL SPECIFICATION left by the said Charles Denton Abel
at the Office of the Commissioners of Patents, with his Petition, on
the 5th June 1868..
I, CHARLES DENTON ABEL, of No. 20, Southampton Buildings,
Chancery Lane, in the County of Middlesex, Patent Agent, do hereby
declare the nature of the said Invention for "A NEW OR IMPROVED STOPPING
MOTION FOR SPINNING MACHINERY," to be as follows:-
This Invention consists in arranging that set of the first drawing
rollers that are upon the driving spindle in spinning machinery loose
upon such spindle but made to revolve therewith by means of clutches.
with shallow rounded or corrugated teeth, which clutches rotate with.

page_text: but can slide upon the spindle and are kept in gear with the fixed
clutch on the drawing roller by means of a helical spring acting
simultaneously upon two such clutches. On the other end of each
drawing roller is formed a ratchet wheel, opposite to the teeth of which
is a pawl formed or fixed on or connected to a lever carried by a spindle
and made to rest with its extremity against the thread as it passes from
the drawing rollers. The lever is thus held in such a position that as
long as the thread against which it rests is entire it keeps the pawl out
of gear with the ratchet wheel on the drawing roller, and this is carried
round by the clutch, but as soon as the thread breaks the pawl falls into
gear with the ratchet wheel and the drawing roller is prevented from
rotating, the shallow rounded form of the clutch teeth allowing the
sliding clutch to be driven back out of gear with the part on the roller
as it rotates with the spindle, while as soon as the thread is mended and
the pawl withdrawn from the ratchet the roller is driven round by
the clutch again. The clutch apparatus and spring situated between
each two such drawing rollers is enclosed by a cylindrical casing passing
from one roller to the other.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charles Denton Abel in the Great Seal Patent
Office on the 1st December 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
DENTON ABEL, of No. 20, Southampton Buildings, Chancery Lane, in
the County of Middlesex, Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifth day of June, 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 sáid Charles Denton Abel, Her special
licence that I, the said Charles Denton Abel, my executors, adminis-
trators, and assigns, or such others as I, the said Charles Denton
Abel, my executors, administrators, and assigns, should' at any time
agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great

page_text: Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "A NEW OR IMPROVED STOPPING MOTION FOR SPINNING MACHINERY," a com-
munication to. me from abroad by Amand Boutemy, Spinner, of Lannoy,
Nord, in the Empire of France, upon the condition (among others) that
I, the said Charles Denton Abel, 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 Charles Denton Abel, 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 thereof, reference being had to the
accompanying Sheet of Drawings, and to the figures and letters marked
thereon, that is to say :-
It is well known that in the frames for spinning flax, hemp, and
other filamentous materials when a thread is broken the feeding rollers
in continuing to deliver the sliver or material for the thread cause
a certain waste, which may be of considerable importance where a
number of frames are employed. Various contrivances have been
proposed for preventing such waste but none of the existing arrange-
ments fulfil perfectly and economically the object desired.
The present Invention consists in a simple and cheap arrangement
of apparatus for the above purpose wherein a disengaging lever brought
directly into action by the breaking of a thread is caused to arrest the
motion of the respective drawing roller only, thus stopping the supply
of material for that particular thread without interfering with the action
of the other parts of the machine.
The construction of such apparatus which it is preferred to employ
is shown on the accompanying Sheet of Drawings. Figure 1 shows a
front elevation of the principal part of the apparatus; Figure 2 shows
a side view thereof; Figure 3 shows the manner in which the apparatus
acts; and Figure 4 shows a detached front view of the disengaging
lever.
The driving spindle A of the frame carries loose upon it the drawing
roller B, which is in gear with and imparts motion to the second drawing

page_text: roller. The roller B is caused to revolve with the spindle A by means
of a spring catch D carried by a sleeve or bush C projecting from the
side of the roller, the catch being caused by the spring G fixed to C
by a screw H or by other suitable means to take into a notch in the
spindle, as shown at Figure 2. F is a lever free to turn on the pin L,
having on its lower end a tail K which in resting against the
thread X, X, that is being spun keeps the lever in the position shown
in full lines in Figure 3, while when the thread X breaks at any point
below the drawing rollers the lever falls into the position shown in
dotted lines. When in this position the upper end of the lever formed
as a hook, as shown, catches on to the projection on the tail of the
catch D and thereby draws the beak of the catch out of the notch in
spindle A, thus allowing the latter to continue to revolve while the
catch and with it the drawing roller is held stationary by the lever F.
By this means it will be seen that as the motion of the drawing roller
is stopped so soon as the thread breaks no waste can take place, and
thus a great saving will be effected in the aggregate where a. number
of these machines are used. When the thread is repaired again the
lever F is made to resume its former position, and the spring catch D
being free to enter the notch in the spindle, motion will again be
imparted to the drawing rollers. In cases where the resistance of the
thread to the drawing rollers is not very great a modification may be
employed based on the same principle of action, but in which the
stopping action is not of so rigid a character; thus the spring may
be a helical spring passing round the spindle and acting on a sliding
nut or clutch with shallow corrugations revolving with the spindle
and pressed by the spring against corresponding corrugations on the
side of the drawing roller, the disengaging lever being made to catch in
a ratchet wheel which stops the motion of the drawing rollers and
throws the clutch out of gear.
Having thus described the nature of this Invention, and in what
manner it is to be performed, as communicated to me by my foreign
correspondent, I wish it to be understood that I do not limit myself to
the precise details of construction shown on the accompanying Sheet
of Drawings, as these may be variously modified without departing from
the nature of this Invention; but what I claim is, the before-described
apparatus for preventing waste in spinning machinery wherein a dis-
engaging lever brought directly into action by the breaking of a

page_text: thread is caused to arrest the motion of the respective drawing roller,
substantially as described.
In witness whereof, I, the said Charles Denton Abel, have
hereunto set my hand and seal, this Thirtieth day of November,
in the year of our Lord One thousand eight hundred and sixty-
eight.
