Year: 1873

page_text: LETTERS PATENT to Hunter Henry Murdoch, of No. 7, Staple Inn,
in the County of Middlesex, Patent Agent, for the Invention of
"IMPROVEMENTS IN CONTINUOUS SPINNING MACHINES."—A communication
from abroad by Guillaume Joseph Snakers, of Verviers, in the
PROVISIONAL SPECIFICATION left by the said Hunter Henry Murdoch
at the Office of the Commissioners of Patents, with his Petition, on
the 22nd May 1873.
I, HUNTER HENRY MURDOCH, of No. 7, Staple Inn, in the County of
Middlesex, Patent Agent, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN CONTINUOUS SPINNING MACHINES," to be as
follows:-
This Invention, as communicated to me, relates to continuous
spinning machines, and consists in the application to such machines of
the improved apparatus herein-after described for drawing or extending
the slivers or threads of fibre under operation to about the required
extent, the said drawing apparatus being placed between the giving out

page_text: rollers and the twisting tubes at that part of the machine where the
slivers are best able to support the drawing operation.
The said drawing apparatus consists of one or more revolving bars
placed on each side of the machine parallel to the fluted rollers, and a
little behind the twisting tubes. The said drawing bars are of rectan- t
gular section, and revolve on their axes or centres. To the narrower
sides of the said bars are affixed card teeth, brushes, bands of roughened
leather, glass, paper, or other suitable material, to which the slivers or
threads under operation will adhere firmly. Upon the other sides of the
said bars are affixed bands or strips of wood or iron, the angular edges 1
of which bands or strips are rounded, and extend on each side nearly to
the surface of the adhesive material herein-before described.
When the said bars rotate the adhesive material on their narrower
sides or surfaces comes in contact with the slivers passing over them.
The said slivers then adhere to the said material, and are drawn forward 1
and elongated thereby. As the rotation of the said bars proceeds the
slivers rest upon the corners of the said bars, and become freed or
detached from the adhesive material. They then receive a further
quantity of twist, thereby acquiring fresh strength to be again subjected
to the drawing process of the rotatory bar. Thus during about a 2
quarter of a revolution of the said bar the slivers receive twist from tho
twisting tubes. During the next quarter of a revolution the said slivers
become attached to the adhesive surface of the bar, and are subjected to
the drawing action thereof. During the next quarter of a revolution
the slivers again become freed from the bar and receive twist, and 1
during the last quarter of a revolution they engage with the second
adhesive surface of the bar, and are again drawn on and elongated.
Several of the said revolving bars may, if required, be mounted on the
same mechine, one before the other, so as to produce a nearly continuous
drawing and twisting action upon the slivers.
To facilitate the drawing of the slivers by the said rotatory adhesive
bars a "wing revolver" may be placed behind the said bars, and caused
to rotate at considerable speed, so as to impart a rapid vibratory motion
to the slivers, and assist the slipping of the fibres one upon the other
during the drawing process.
The rotation of the adhesive drawing bars, herein-before described,
corresponds in velocity with that of the funnt donning llam

page_text: machine, so as to supply to the said rollers nearly as much length of
thread or sliver as they can draw forward, in order that the said rollers
may have but little drawing action upon the said slivers, as between the
said rollers and the tube fingers the slivers are untwisted and have too
little cohesion to bear the strain.
This Invention also consists of an improved form to be given to the
twisting tube fingers of continuous spinning machines. The said fingers
are shaped somewhat in the form of the letter Y, the two upper arms
being bent and fixed to the tube, whilst the lower arm is pointed at its
end, and extends between the two front drawing rollers to near their
point of contact.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Hunter Henry Murdoch in the Great Seal Patent
Office on the 22nd November 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HUNTER
HENRY MURDOCH, of No. 7, Staple Inn, in the County of Middlesex,
Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria by Her Letters
Patent, bearing date the Twenty-second day of May, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Hunter Henry Murdoch, Her special
license, that I, the said Hunter Henry Murdoch, my executors,
administrators, and assigns, or such others as I, the said Hunter Henry
Murdoch, 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 CONTINUOUS SPINNING MACHINES," a communication
to me from abroad by Guillaume Joseph Snakers, of Verviers, in
the Kingdom of Belgium, Spinner, upon the condition (amongst
others) that I, the said Hunter Henry Murdoch, my executors or admi-
nistrators, by an instrument in writing under my, or their, or one
of their hands and seals, should particularly describe and ascertain the

page_text: 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 Hunter Henry Murdoch, 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, that is to say :-
:―
This Invention, as communicated to me, relates to continuous
spinning machines, and consists in the application to such machines of
the improved apparatus herein-after described for drawing or extending
the slivers or threads of fibre under operation to about the required
extent, the said drawing apparatus being placed between the giving-out
rollers and the twisting tubes at that part of the machino where the
slivers are best able to support the drawing operation.
The said drawing apparatus consists of one or more revolving bars
placed on each side of the machine parallel to the fluted rollers, and a
little behind the twisting tubes. The said drawing bars are of rectan-
gular section, and revolve on their axes or centres. To the narrower
sides of the said bars are affixed card teeth, brushes, bands of roughened
leather, glass, paper, or other suitable material, to which the slivers or
threads under operation will adhere firmly. Upon the other sides of the
said bars are affixed bands or strips of wood or iron, the angular edges of
which bands or strips are rounded, and extend on each side nearly to the
surface of the adhesive material herein-before described.
When the said bars rotate the adhesive material on their narrower
sides or surfaces comes in contact with the slivers, passing over them.
The said slivers then adhere to the said material, and are drawn forward
and elongated thereby. As the rotation of the said bars proceeds the
slivers rest upon the corners of the said bars, and become freed or
detached from the adhesive material. They then receive a further
quantity of twist, thereby acquiring fresh strength to be again subjected
to the drawing process of the rotatory bar. Thus during about a
quarter of a revolution of the said bar the slivers receive twist from the
twisting tubes. During the next quarter of a revolution the said slivers
become attached to the adhesive surface of the bar, and are subjected to
the drawing action thereof. During the next quarter of a revolution

page_text: the slivers again become freed from the bar and receive twist, and
during the last quarter of a revolution they engage with the second
adhesive surface of the bar, and are again drawn on and elongated.
Sevoral of the said revolving bars may, if required, be mounted on the
3 same machine, one before the other, so as to produce a nearly continuous
drawing and twisting action upon the slivers.
To facilitate the drawing of the slivers by the said rotatory adhesive
bars a "wing revolver" may be placed behind the said bars, and caused
to rotate at considerable speed, so as to impart a rapid vibratory motion
to the slivers, and assist the slipping of the fibres, one upon the other
during the drawing process.
The rotation of the adhesive drawing bars, herein-before described,
corresponds in velocity with that of the front drawing rollers of the
machine, so as to supply to the said rollers nearly as much length of
thread or sliver as they can draw forward, in order that the said rollers
may have but little drawing action upon the said slivers, as between tho
said rollers and the tube fingers the slivers are untwisted, and have too
little cohesion to bear the strain.
This Invention also consists of an improved form to be given to the
twisting tube fingers of continuous spinning machines. The said fingers
are shaped somewhat in the form of the letter Y, the two upper arms
being bent and fixed to the tube, whilst the lower arm is pointed at its
end, and extends between the two front drawing rollers to near their
point of contact.
Having explained the nature of this Invention, as communicated to
me, I will proceed to describe, with reference to the accompanying
Drawings, the manner in which the same is to be performed.
Figure 1 represents an end elevation of a continuous spinning machine
with improvements applied thereto according to this Invention ;
Figure 2 is a transverse section of the same.
The same letters of reference indicate liko parts in Figures 1 and 2
wherever they occur.
The slivers or threads of fibre passing from the giving out rollers to
the twisting tubes are indicated by the dotted lines a, a; b are the
"wing revolvers" or revolving beaters, which are caused to rotato at

page_text: considerable speed so as to impart a rapid vibratory motion to the slivers,
and assist the slipping of the fibres one upon the other during the
drawing process. Each of the said "wing revolvers" 6 consists of two
rods or bars of iron mounted on arms projecting from a central axis, as
shown, the said rods being situated one on each side of the said axis. e, e, E
are the revolving bars for drawing forward and elongating the slivers a
before they enter the twisting tubes t. The said bars e are of rectan-
gular section, and revolve upon their axes e¹. To the narrower sides of
the said bars e are affixed card teeth or suitable adhesive material, as
described, to which the slivers or threads will adhere firmly,
and upon
the other sides of the said bars or affixed bands or strips of wood or
iron, as herein-before described. Rotatory motion is communicated to
the said revolving bars e by wheel gearing actuated from the fluted
rollers c which deliver the thread to the spindles d, d, (Figure 2).

To facilitate the joining of broken threads the pressing rollers r, which 1
rest upon the fluted rollers c, are carried by supports S mounted as
shown, so as to be capable of turning on their axes. When a broken
thread has to be joined the roller r is removed from the lower notches or
slots of the support S, and is placed in the upper notches or slots S¹ of
the same. The support S then falls backward, and causes a projection 2
upon it to enter a recess in the pulley of the tube t, and to stop the said
tube. It is then easy to pass into the inside of the said tube the thread
which is to be joined.
Having now described the nature of this Invention, and the manner
in which the same is to be performed, I wish it to be understood that I
do not confine myself to the precise details herein-before described and 2
illustrated in the accompanying Drawings, as the same may be varied
without departing from the nature of the said Invention; but I claim as
the said Invention of "improvements in continuous spinning machines,-
Firstly. The adaptation or application to such machines of the
revolving bar or bars e, herein-before described and illustrated in the 3
accompanying Drawings, for drawing or extending the slivers operated
upon in such machines.
Secondly. The combination of the said revolving bar or bars e with
one or more wing revolvers or rotatory beaters 6, essentially as herein-
before described and illustrated in the accompanying Drawings, and for 3

page_text: Thirdly. The application to machines constructed according to this
Invention of the supports S for facilitating the joining of broken
threads, the said supports being constructed and arranged essentially
as herein-before described and illustrated in the accompanying
Drawings.
In witness whereof, I, the said Hunter Henry Murdoch, have
hereunto set my hand and seal, this Twenty-second day of
November in the year of our Lord One thousand eight hundred
and seventy-three.

B. WILLCOX,
his Clerk.
