Year: 1866

page_text: LETTERS PATENT to John Dunn, of No. 6, Old Jewry, in the City of
London, Gentleman, for the Invention of "IMPROVEMENTS IN SPINNING
WOOL AND OTHER FIBROUS MATERIALS."-A communication from abroad by
Ferdinand Spineux of Liége Belgium.
PROVISIONAL SPECIFICATION left by the said John Dunn at the Office of
the Commissioners of Patents, with his Petition, on the 17th September
1866.
I, JOHN DUNN, of No. 6, Old Jewry, in the City of London, Gentleman, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN SPINNING
WOOL AND OTHER FIBROUS MATERIALS," a communication to him from abroad by
Ferdinand Spineux, of Liége, Belgium, to be as follows:-
One part of my said Invention consists of a mode of constructing and
arranging certain apparatus or parts of machinery employed in the formation
of a rove or sliver used in spinning, and in the formation of a thread, whereby
in performing simultaneously the two operations of drawing and twisting the
rove or sliver, or partially formed thread, I am enabled to impart the amount
of twist which is necessary for the even drawing by the rollers, and to vary
the proportion between the twist and the draft. This apparatus I construct
in the form of two open pipes or hollow pieces having a common axis, and
capable of rotating independently of each other. To one of these pipes or

page_text: hollow pieces I attach the drawing rollers which are to act upon the rove or
sliver, or partially formed thread, and to one of the drawing rollers I attach a
worm wheel; to the other pipe or hollow piece I attach an enlarged hollow
box or end piece having a worm or screw thread traced upon its internal surface,
which is capable of engaging with the teeth of the aforesaid worm wheel. The
two pipes or hollow pieces are fitted the one inside the other, so as to form
one hollow piece, along the axis of which the rove or sliver or partially formed
thread passes from the feed rollers to the drawing rollers, and being grasped
by the drawing rollers the rove or sliver or partially formed thread is twisted
by the rotation of the piece which carries the rollers, and is at the same time
drawn by the rotating of the drawing rollers upon their own axes, which latter
motion is imparted to the same by the rotation of the piece carrying the worm
or screw thread. By connecting each pipe or hollow piece separately with
suitable driving apparatus I am enabled to vary at will the velocities with
which they separately rotate, and thus to regulate the proportion between the
amounts of draw and twist which may be imparted to the rove or sliver or
partially formed thread: In place of employing a worm or screw thread and
a worm wheel for the purpose of driving the drawing rollers, I sometimes
make use of bevil wheels or other suitable gearing to effect the same object.
Another part of my Invention consists of a mode of constructing an
apparatus so as to produce simultaneously the combined effect of drawing and
twisting the rove or sliver or partially formed thread by the aid of a single
roller upon which the rove or sliver or partially formed thread is wound. For
this purpose I construct an apparatus of two hollow pipes or pieces, as before
described, to one of which I attach a bevil wheel or other suitable gearing,
and to the other I attach a single cylinder or roller having upon its axis a
bevil wheel or other gearing, so as to be capable of engaging with and being
driven by the first-mentioned bevil wheel or other gearing, and by a suitable
guide I cause the rove or sliver or partially formed thread to be wound one or
more times evenly upon the cylinder or roller, so that the friction between the
rove or sliver or partially formed thread and the cylinder or roller
upon which
it is wound may prevent the rove or sliver or partially formed thread from
slipping, and then I cause the said cylinder or roller to wind the said rove or
sliver or partially formed thread upon itself more rapidly than the same is
delivered to it, whereby the rove or sliver or partially formed thread is drawn
as may be required, and the twisting is at the same time effected in the same
manner as in the apparatus forming the first
part of
my Invention.

page_text: SPECIFICATION, filed in pursuance of the conditions of the Letters Patent
and of an Order of the Lord Chancellor, by the said John Dunn in the
Great Seal Patent Office on the 13th April 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
DUNN, of No. 6, Old Jewry, in the City of London, Gentleman, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the 17th day of September, in the year of our Lord
One thousand eight hundred and sixty-six, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said John Dunn, Her special licence that I, the said John Dunn, my
executors, administrators, and assigns, or such others as I, the said John
Dunn, 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 SPINNING WOOL
AND OTHER FIBROUS MATERIALS," being a communication to me from abroad by
Ferdinand Spineux, of Liege, Belgium, upon the condition (amongst others)
that I, the said John Dunn, my executors or administrators, by an instru-
ment 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 John Dunn, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
Specification thereof, reference being had to the accompanying Drawings, that
is to say:
One part of the said Invention consists of a mode of constructing and
arranging certain apparatus or parts of machinery employed in the formation
of a rove or sliver used in spinning wool and other fibrous materials, and in
the formation of a thread whereby in performing simultaneously the, two
operations of drawing and twisting the rove or sliver, or partially formed
thread, I am enabled to impart the amount of twist which is necessary for the
even drawing by the rollers and to vary the proportion between the twist and
the draft. This apparatus is shown in Figures 1, 2, 3, and 4 of the accom-

page_text: panying Drawings, in which similar parts are marked with similar letters of
reference.
To one extremity of a tube a, a, there is attached a driving pulley A, and
to the other end a frame carrying two drawing rollers d, d; to each of these
rollers, or to one of them, as may be preferred, there is attached a worm
wheel c, the teeth of which engage with a suitable spiral worm or screw
thread shewn at 6 in Figures 1 and 4; this spiral worm or screw thread is
formed upon the inside of a second hollow tube l, l, enlarged at one end or
provided with a flange, or otherwise shaped so as to cause the said worm or
screw thread to engage with the teeth of the above-mentioned worn wheels or
wheel. To the tube 1, 1, there is attached a driving pulley B, and where the
parts are fitted together, as shown in Figures 1 and 2, the tube l, l, is slipped
upon the tube a, a, which is made to turn easily within it, so that either tube
can be caused to rotate independently of the other in whichever direction
circumstances may require. The pulleys A and B are now connected with
suitable driving apparatus of such a kind that different velocities of rotation
can be imparted to each simultaneously, and therefore, also, to the respective
tubes connected with them. This apparatus is placed between the ordinary
feed rollers of a suitable roving or spinning machine, and the flier and bobbin,
or the cop upon which the rove or sliver or partially formed thread is to be
wound, and the said rove or sliver or partially formed thread is caused to pass
from the ordinary feed rollers, above mentioned, along the axis of the tube a, a,
and between the drawing rollers d, d, at its extremity, and being grasped
between these rollers; it is in this way capable of receiving a twist by the
rotation of the tube a, a, and at the same time of being drawn by the action
of the drawing rollers, to which a proper and distinct motion of rotation about
their own axes is imparted by the agency of the tube l, l, which carries the
said worm or screw thread. The action will be evident from the consi-
deration that so long as any difference in the motion of rotation exists between
the tubes a, a, and I, 1, the said worm or screw thread will have a motion of
rotation equal to this difference as between it and the worm wheels or wheel
with which it engages, and will impart a motion of rotation to the latter. I
arrange, therefore, my driving apparatus so as to impart different velocities of
rotation to the pulleys A and B, and therefore, also, to the respective tubes
connected with them, and am in this way enabled to employ my apparatus so
as to vary at will and otherwise to regulate the amount of draw and twist
which I may desire to impart to the rove or sliver or partially formed thread.
Instead of employing the combination of a spiral worm or screw thread with
a worm wheel or wheels, as above described, for the purpose of driving the

page_text: drawing rollers, I sometimes effect the same object by the use of bevil wheels,
as shewn in Figures 5 and 6, or by other suitable gearing.
:
Another part of my Invention consists of a mode of constructing an apparatus
so as to produce simultaneously the combined effect of drawing and twisting
the rove or sliver or partially formed thread, by the aid of a single roller
upon which the said rove or sliver or partially formed thread is wound.
For this purpose I construct an apparatus shewn in Figures 7, and 8, which
is in all respects identical with that already described except that I substitute
for the two drawing rollers above described a single roller D, Figures 7 and 8,
attached to a worm wheel C or a bevil wheel as shown, or to other suitable
gearing, and which is capable of engaging with a spiral worm or screw thread
b, or with a bevil wheel or other gearing upon the end of the tube 1, 1, as
before described, and I cause the rove or sliver or partially formed thread
to be wound one or more times evenly upon the cylinder or roller, by means
of a guide e, e, with nicks in it as shown in Figures 7 and 8, so that the friction
between the rove or sliver, or partially formed thread, and the cylinder or roller
upon which the same is wound may prevent the said rove or sliver or partially
formed thread from slipping, and then I cause the tubes a, a, and I, 1, to
rotate with different velocities in such a manner that the roller D has a
proper and distinct motion of rotation upon its own axis imparted to it during.
the time that the twist is being given to the said rove or sliver or partially
formed thread as before described, and the result is that the said rove or sliver
or partially formed thread is wound upon the said cylinder or roller more
rapidly than the same is delivered to it, and that the drawing is thereby
effected in any degree which may be required, while the twisting is at the
same time effected in the same manner as in the apparatus forming the
first part of my Invention. In respect of the form of the last-mentioned
cylinder or roller I remark that I find it advantageous to increase its diameter
gradually towards the end where the rove or sliver or partially formed
thread finally leaves it, whereby any slipping of the same is rendered nearly
impossible.
Having now fully described the nature of the said Invention and the
manner in which the same is to be performed, I declare that I do not intend
to claim any of the mechanical parts of the apparatus above described separately
and apart from the application and combination thereof, as herein-before
described, as being any part of the Invention, and that I do claim as of the
Invention,-
First, the combination of parts or mode of constructing and arranging

page_text: amount..of twist which is necessary for the even drawing by the rollers,
and to vary the proportion between the draft and the twist, as herein-before
described.
:
Secondly, the combination of parts or mode of constructing and arranging
an apparatus or parts of machinery whereby the combined effect of drawing
and twisting is produced by the aid of a single roller upon which the rove or
sliver or partially formed thread is wound as herein-before described.
In witness whereof I, the said John Dunn, have hereto set my hand
and seal, this 12th day of April, in the year of our Lord One thousand
eight hundred and sixty-seven.
Signed, sealed, and delivered by the
above-named. John Dunn, in the
presence of,
J. BOWER BARRETT,

London.
