66, Chancery Lane, in the County of Middlesex, Civil Engineer, for the
Invention of "IMPROVEMENTS IN MACHINERY FOR SPINNING OR TWISTING
PROVISIONAL SPECIFICATION left by the said William Edward Newton
at the Office of the Commissioners of Patents, with his Petition, on the
21st November 1856.
I, WILLIAM EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane,
in the County of Middlesex, Civil Engineer, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN MACHINERY FOR SPINNING OR TWISTING
FIBROUS SUBSTANCEB," to be as follows:-
The Invention, which forms the subject of the present application, consists
in the application to all kinds of spinning machinery of what the Inventor
calls a "whistle," which is somewhat similar to the tube employed in machi-
nery for spinning cotton, and to that used in carding engines for carding wool.
In these two applications the tube is employed for compressing or consolidating
all the filaments of a sliver, in order to give it sufficient consistence without
the necessity of twisting, which in some cases is injurious to the quality of the
thread. The tube is also mounted on a hinge joint, which admits of its rising.
and following the surface of the bobbin as its diameter increases by the yarn
being wound thereon.

page_text: In the improvement which constitutes the present Invention, the tubo on
the contrary is mounted between the drawing rollers and front rollers, in such
a manner that it can neither riso nor fall.
The whistle is composed of a tube provided with a pulley, which is actuated
by means of a band driven in any convenient manner; this tube is mounted
in a fixed bearing or support, and at about the middle it is provided with a
pin which passes through it, and offers an obstruction to the passage of the
sliver in a straight line. As the sliver passes through the tube it is necessarily
bent out of the straight line by the pin which passes across the tube, and to
this latter a rotary motion is communicated by means of the pulley and strap
above mentioned. By means of this obstruction the sliver is obliged to turn
with the tube, and therefore is vigorously twisted between the drawing rollers
and the obstructing pin, but when it passes beyond this latter the twist comes
out of the sliver, so that when the sliver arrives at the front rollers there is no
twist in it, and it is ready to receive the proper amount of twist from the
bobbin and flyer.
This whistle" or tube serves, to prevent the fibres of the yarn from rolling
round or enveloping the drawing roller or its pressing roller. It also serves to
cause all the filaments of the sliver to bo incorporated therewith, and to tako
up and solidify all the down which might otherwise project from the surface of
the sliver.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Edward Newton in the Great Seal Patent Office on
the 21st May 1857.

page_text: make, use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for "IN-
PROVEMENTS IN MACHINERY FOR SPINNING OR TWISTING FIBROUS SUBSTANCES,"
being a communication from abroad, upon the condition (amongst others) that
I, the said William Edward Newton, by an instrument in writing under my
hand and seal, 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 William Edward Newton, 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, reference being had to the Drawing hereunto annexed,
and to the letters and figures marked thereon (that is to say):-
This Invention of "Improvements in Machinery for Spinning or Twisting
Fibrous Substances," as communicated to me by my foreign correspondent,
consists in the application to all kinds of spinning machinery of what the
Inventor calls a "whistle," which is somewhat similar to the tube employed in
machinery for spinning cotton, and to that used in carding engines for carding
wool. In these two applications the tube is employed for compressing or con-
solidating all the filaments of a sliver, in order to give it sufficient consistence
without the necessity of twisting, which in some cases is injurious to the quality
of the thread. This tube is also mounted on a hinge joint, which admits of
its rising and following the surface of the bobbin as its diameter increases by
the yarn being wound thercon. In the improvement which constitutes the
present Invention, the tube on the contrary is mounted between the drawing
rollers and front roller, in such a manner that it can neither rise nor fall.
The "whistle" is composed of a tube provided with a pulley, which is
actuated by means of a band driven in any convenient manner; this tube is
mounted in a fixed bearing or support, and at about the middle it is provided
with a pin which passes through it, and offers an obstruction to the passage of
the sliver in a straight line. As the sliver passes through the tube it is neces-
sarily bent out of the straight line by the pin which passes across the tube,
and to this latter a rotary motion is communicated by means of the pulley and
strap above-mentioned. By means of this obstruction the sliver is obliged to
turn with the tube, and therefore is vigorously twisted between the drawing
rollers and the obstructing pin, but when it passes beyond this latter the twist
comes out of the sliver, so that when the sliver arrives at the front rollers
there is no twist in it, and it is ready to receive the proper amount of twist

page_text: from the bobbin and flyer. This "whistlo" or tube serves to prevent the
fibres of the yarn from rolling around or enveloping the drawing roller or its
pressing roller. It also serves to cause all the filaments of the sliver to be
incorporated therewith, and to take up and solidify all the down which might
otherwise project from the surface of the sliver. In the accompanying
Drawing, the "whistle" or tubo is shewn as applied to a spinning frame.
A is the drawing roller, with its pressing roller B; the front rollers are shewn
at C, D; and E, F, is the "whistle," through which the thread passes, as
shewn by the red line; and G is the flyer, provided with its bobbin H, on which
the thread is wound.
The whistle, which may vary in form and arrangement according to the
nature of the machinery to which it is applied, is represented in the Drawing
as consisting of a tubo provided with a pulley I, for the reception of a driving
band, by which rotary motion is communicated to it, and the tube is mounted
in bearings in a fixed bracket, and is provided with a pin J, which traverses
it in the direction of its breadth for the purpose of preventing the sliver from
passing through the tube in a straight line. The tube is mounted (as above-
mentioned) between the drawing roller and front roller, and the speed of the
rotary motion imparted to it will vary in proportion to the thickness or sub-
stance of the sliver. It will be understood that as the ribbon is arrested in
its passage through the tube by the pin J. it will thereby be forced to turn
with the tube, and on coming from the drawing roller the sliver will have a
strong twist given to it, which it will lose on passing beyond the pin, so that
on arriving at the front roller it will be without twist, and ready to receive any
that may be imparted to it by the flyer, or otherwise previously to its being
wound upon the bobbins. The tendency of fibrous substances to lap round
the drawing and pressing rollers is well known to practical spinners, especially
when the roving is of a certain fineness, and the evils occasioned by the rough
fibres produced thereby will be well understood. Besides the inferior quality
of the thread that is produced, and which is weakened in cortain parts, the
pressing rollers are deteriorated, and the largo quantity of waste fibre causes
stoppages, and consequently a diminution in the product. These evils are in
many cases considerably increased, either by the dampness or the excessive
dryness of the atmosphere, and also by other causes which it is unnecessary to
enumerate.
By the employment of the "whistle" or tube which forms the subject of
the present Invention, the lapping round or enveloping the drawing roller is
entirely prevented, and by preventing the formation of loose projecting fibres
the above evils are obviated, the thread produced is also much more perfect,

page_text: inasmuch as all the fibres which are intended to form it are by this means
incorporated therewith; the "whistle" or tube by its motion (the speed of
which is proportioned to the fineness of the roving) producing a strong twist
upon the substance exposed to its action on coming from the drawing roller,
which twist disappears entirely in the space left free between the front part of
the "whistle" and the front roller. The effect of this falso twist is to take up
the loose fibres immediately they appear, and incorporate them in the sliver or
roving.
Having now described this Invention, as communicated to me by my foreign
correspondent, I desire it to be understood that what I claim under the above
in part recited Letters Patent is, the application of the rotating tube (which, by
reason of the object which it is intended to effect, I shall call the " condensing
whistle,") to machinery for drawing, roving, slubbing, and spinning, and
generally to all kinds of machinery for spinning fibrous substances, generally
in combination with a guide roller, for the purpose of consolidating or con-
densing all the fibres of the yarn on coming from the drawing rollers, by
imparting to it a false twist, and by that means preventing the deposit of
loose fibres on the rollers, and producing a smooth yarn free from down or
loose projecting fibres.
In witness whereof, I, the said William Edward Newton, have hereunto
set my band and seal, the Twentieth day of May, in the year of our
Lord One thousand eight hundred and fifty-seven.
Witness,
