Year: 1871

page_text: LETTERS PATENT to Robert Turner, of the City of Manchester, in
the County of Lancaster, Cotton Spinner, for the Invention of
"IMPROVEMENTS IN MACHINERY FOR PREPARING, TWISTING, OR SPINNING
COTTON AND OTHER FIBROUS MATERIALS."
Scaled the 22nd August 1871, and dated the 4th March 1871.
PROVISIONAL SPECIFICATION left by the said Robert Turner at the
Office of the Commissioners of Patents, with his Petition, on the
4th March 1871.
I, ROBERT TURNER, of the City of Manchester, in the County of
Lancaster, Cotton Spinner, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MACHINERY FOR PREPARING, TWISTING, OR
SPINNING COTTON AND OTHER FIBROUS MATERIALS," to be as follows:-
The accompanying Drawing is a section showing the parts herein-after
mentioned and referred to by letters.
My improvements are made upon those for which Letters Patent
were granted to me, No. 3712, dated December Twenty-third, Onc
thousand eight hundred and sixty-nine, and consist in drawing two or

page_text: "
more slivers in the same "boss of the drawing rollers, and then
doubling and twisting them by my Patent arrangement of mechanism;
also in carrying the plate marked 9 in the Specification of my said
Patent by connecting it with the central tube or hollow shaft (e) and
in driving the calender rollers (4) by a skew bevel wheel at the lower I
end of the external tube on hollow shaft (f), which gears with a wheel
upon one end of the axis of one of the calender rollers. The coiler
plate (k) by this arrangement is driven by wheels similarly arranged to
those described in the Specification of my said Patent for conveying
motion from the coiler to the calender.
By my improved arrangement the arms f¹ for carrying the plate, the
arm c¹ for driving the annular wheel, and the annular wheel itself aro
dispensed with.
My Invention also consist in an improved mode of fastening the
clip by jointing a catch to turn across the hook of the spring tongue;
also in dispensing with the jointed clip fastener, and employing a solid
hoop arranged on pins acting within inclined slots to lift the hoop when
the "can" is to be removed.
My Invention further consist in employing cans or cylinders accurately
constructed and intended to be used only in the twisting and coiling
machine, and not for conveying the coiled material from one machine to
another, and in employing with such cans or cylinders moveable bottoms
which are slided down the can or cylinder as it fills, the movement of
the bottom being resisted by friction. I prefer to mount theso move-
able bottoms on a central solid or hollow rod, with which they are
connected by a key groove so as to rotate therewith, their sliding
inovement upon the rod being resisted by the friction caused by a
spring or other arrangement. The lower end of the rod is fitted by a
square or other means into the table plate that carries the " ог
cylindor, or in the bottom of the said can so as to rotato with it,
and a spring is provided either in the hollow of the lower end of the
rod or in the table to push the rod, and thus the moveable bottom
upwards, so as to press against the coiler plate at the beginning of
a new filling" of the "can." When the "can" is full the material is
withdrawn by means of the rod, and it may be immediately transferred
to an ordinary "can" for transport to other machines.

My Invention further consists in constructing the can so as to be
secured to or form part of the table on which it rotates, and in forming

page_text: a bearing for it at its upper end, and in arranging so that the bearings
or frame carrying the coiler mechanism and the drawing rollers are all
connected together on the same frame, arranged so that all the parts
from one end of the frame to the other can be slided backwards
from the front of the "cans" when doffing, or at other times, by means
of a rack and pinions and a shaft passing from end to end of the
machine.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Robert Turner in the Great Seal Patent Office
on the 2nd September 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
TURNER, of the City of Manchester, in the County of Lancaster, Cotton
Spinner, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of March, in the year of
our Lord One thousand eight hundred and seventy-one, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Robert Turner, Her special license that I,
the said Robert Turner, my executors, administrators, and assigns, or
such others as I, the said Robert Turner, 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 MACHINERY FOR PREPARING, TWIST-
ING, OR SPINNING COTTON AND OTHER FIBROUS MATERIALS," upon the condition
(amongst others) that I, the said Robert Turner, by an instrumcut
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 Robert Turner, do hereby declare

page_text: be performed, to be particularly described and ascertained in and by
the following statement and the accompanying Drawings (that is to
say) :—
My improvements are made upon those for which Letters Patent
were granted to me, No. 3712, dated the Twenty-third day of December,
in the year of our Lord One thousand eight hundred and sixty-nine, and
consist in drawing two or more slivers in the same "boss" of the
drawing rollers, and then doubling and twisting them by my patent
arrangement of mechanism; also in carrying the twist plate, marked g
in the Specification of my aforesaid Patent, by connecting it with the
central tube or hollow shaft (e), and in driving the calender rollers (1)
by a skew bevil wheel at the lower end of the external tube or hollow
shaft (), which gears with a wheel upon one end of the axis of one of
the calender rollers. The coiler plate () by this arrangement is driven
by wheels similarly arranged to those described in the Specification
of my said Patent for conveying motion from the coiler to the
calender.
By my improved arrangement the arms (5) for carrying the twist
plate, the arm (l') for driving the internal toothed annular wheel, and
the annular wheel itself (all described in the Specification of my said
Patent) are dispensed with.
C
My Invention also consists in an improved mode of securing the
can” by substituting a solid hoop in place of the clip (4), described in
the Specification of my said Patent. This hoop may be made to lift
directly or arranged with pins and inclined slots so that the hoop is
lifted by slightly rotating it when the "can" is to be removed or
replaced.
My Invention also consists in employing "cans" or cylinders accurately
constructed and intended to be used only in the twisting and coiling
machine, and not for conveying the coiled material from one machine to
another, and in employing with such cans or cylinders moveable bottoms
which are slided down the can or cylinder as it fills, the movement of
the bottom being resisted by friction. I prefer to mount this moveable
bottom on a central solid or hollow rod with which it is connected by a
key groove, which fits a key length way of the rod, so that the bottom
will rotate with the rod, the sliding movement being resisted by the
friction caused by a spring formed of india-rubber, steel, or other
material or by other suitable arrangement. The lower end of the rod is

page_text: itted by a square hole or other means on to a pin in the bottom of the
can" or into the table plate that carries the can or cylinder, so that it
vill rotate therewith, and a spring is provided either in the hollow of
the lower end of the rod or in the table to push the rod and thus the
movcable bottom upwards so as to press against the coiler plate at the
beginning of a new filling of the can. When the can is full the material
s withdrawn by means of the rod, and it may be immediately transferred
to an ordinary can for transport to other meaking
will rotate therewith, and a spring is provided either in the hollow of
the lower end of the rod or in the table to push the rod and thus the
moveable bottom upwards so as to press against the coiler plate at the
beginning of a new filling of the can. When the can is full the material
s withdrawn by means of the rod, and it may be immediately transferred
to an ordinary can for transport to other machines.
Fig. 1 is a vertical section illustrating my improvements; Fig. 2 is a
plan section of part of the mechanism; Fig. 3 is a front elevation, and
Fig. 4 a plan view.
Figs. 3 and 4 illustrate my improved mode or arrangement for drawing
two or more slivers by one boss of the drawing rollers, and twisting them
by my improved combined twisting and coiling mechanism. As illus-
trated three slivers (a¹) are supposed to be drawn by one boss (a) and
are then taken to the twisting tube e; c and d are two rails supposed to
pass the length way of a frame, these rails form the bearings for the
tubes (e). The upper bearing of each tube e is in the upper rail (c), the
lower bearing is in the boss (ƒ) of a wheel (*) having its bearing in
the lower rail (d); j is a shaft that passes from end to end of the frame,
and has a bevil wheel upon it to drive the upper mechanism for cach
can." This bevil geers with one upon a stud i that is fast to two spur
wheels. The spur wheel e³ drives the wheel e² fast upon the tube c,
and the spur wheel drives the wheel f* loose upon the tube e, and
upon the boss of the wheel ƒ a spur wheel f' is secured that drives
one at the upper end of a vertical shaft, having bearings in a stand ƒ”,
as shown. The lower end of the tube (e) divides into two branchics (c¹)
to carry the twist plate g which is cast solid with the tube (e). In the
twist plate the coiler plate k is fitted and held up by four pins (**)
through its rim as shown, and it is rotated by a ring wheel supported
on three studs secured in the coiler plate k, this wheel gearing with
a wheels on the lower end of the vertical shaft ƒ³, upon which there is
also a skew bevil wheel f' that gears with one secured upon one end of
one of the two calender rollers which are geared together by spur
wheels . One roller (1) has bearings in the branch (e¹) from the
tube (e) as shown, the other in an adjustable bearing which allows its
roller to be set nearer to or further from the roller in the fixed bearing.

page_text: is the tube secured in the coiler plate which conveys the twisted sliver
from the under side of the calender rollers through the coiler plate to
the can; p is the table for rotating the can, arranged as shown by Figs.
6 and 7 of the Specification of my aforesaid Patent. The can bottom
is of cast metal with a stud (n²) in its centre to fit the lower end of a
tube (9) of thin metal or tin plate. This tube may have a cross pin in
it to fit a slit in the stud (n³) so that the tube will be carried round with
it. This tube q slides in the lower end of a longer tube or rod q' and
the two are connected by a cross pin q³ secured in the outer rod or tube,
and passing through slots in the two opposite sides of the lower tube (7);
q³ is a helical spring which abuts against the end of the lower tube (9)
and upon a cross piece in the rod or tubo which is thus forced upwards
against the under side of the coiler plate ; q* is the moveable bottom
made of tin plate hollow with a hole through its centre to fit the rod
or tube q', and within it a ring of india-rubber q³ is secured by pins
soldered or otherwise secured in the bottom. This ring grasps the rod q¹
tightly and gives friction sufficient to produce the required amount of
resistance to the descent of the bottom as the material is coiled in the
can. Each coil of twisted material just encloses the rod within its circle,
the inner periphery touching the surface of the rod so that when the rod
is withdrawn there is a hole left in the centre. The can is secured at
the upper end by the hoop which rests when the machine is working
upon the edge of the twist plate (9) as shown. It may be lifted vertically
when the can is to be removed or arranged upon pins in slots as shown
in dotted line so as to lift vertically when slightly rotated.
I have now particularly described the nature of my Invention, and
the mode of carrying it into effect, and claim as my Invention,-
Firstly. The drawing of two or more slivers by one boss, and then
twisting and coiling the same at one operation, substantially as herein-
before described.
Secondly. The combination and arrangement of the twist plate (9),
coiler plate (k), and calender rollers (1), and mode of driving the
same, substantially as herein-before described and illustrated by the
Drawings.
Thirdly. The hoop (1) as combined with the twist plato y and can (~),

.In witness whereof I, the said Robert Turner, have hereunto set
my hand and seal, this First day of September, in the year of
our Lord One thousand eight hundred and seventy-one.
