Year: 1869

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."
Sealed the 17th June 1870, and dated the 23rd December 1869.
PROVISIONAL SPECIFICATION left by the said Robert Turner at the
Office of the Commissioners of Patents, with his Petition, on the
23rd December 1869.
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:—
My Invention relates, firstly, to a method of twisting slivers or threads
of fibrous material, and at the same time coiling the slivers or threads so
twisted in a "can" or other receptacle, by which means complicated
mechanism hitherto used in preparing machinery for giving varying
speeds to the winding and traverse motion is dispensed with, as the

page_text: speeds by my Invention for both twisting and winding or coiling are
constantly the same, and a traverse motion is not required, and in
addition to these advantages the twisted material is protected against
the effects of the atmosphere and centrifugal force, which tend to throw
the loose fibres outwards.
My Invention consists in a modification and adaptation of the
mechanism hitherto used for coiling slivers into a "can," and may be
described generally as giving motion to effect the twisting of the sliver
or thread by rotating the entire coiling mechanism, in addition to its
ordinary movements; but more particularly my improvements consist
as follows:-In mounting the "can" or other receptacle on a table or
in a skeleton frame made to rotate by wheelwork or other suitable
means. The upper end of the "can" comes under or against a circular
plate carried by a ring in the skeleton frame, or sustained or suspended
in a rotating ring or upon a fixed beam. The circular plate can be
rotated by wheelwork or other suitable means. In the circular plate
and excentric to it another circular plate is arranged, which I call the
coiler plate, and this plate may be made to gear with an internal wheel,
carried upon the circular plate and driven by wheelwork, or in any other
convenient manner. In this coiling plate a tube is arranged, which
conducts and coils the twisted sliver or thread into the "can;" this
sliver or thread after coming from the rollers first passing through a
central guide tube, which may either remain stationary or be rotated.
The "can" or receptacle for the twisted material is made with a false or
movable bottom, which may when empty be held up by a spring or
weight, the bottom descending as the "can" fills, or the bottom may be
arranged to have a given amount of friction upon the sides of the " can,"
so as to be gradually forced down as it fills. The table for the "can
may be arranged to screw up and down to allow of its being removed
and replaced, or it may be held up by a spring or other means. The
table for the "can" or the skeleton frame is driven at the speed required
to give the twist, and the circular plate and coiler plate are driven at
either a little greater or slower speed (as may be preferred) to effect the
coiling. A number of these twisting coilers may be arranged together
in a frame, and may be driven by the same shafts.

"
Secondly. My improvements relate to the ordinary coiler, and to the
"cans" to be used therewith, and consist in making the bottoms
movable up and down like a piston to slide down from the top to the

page_text: bottom as the "can" fills, the movement of the bottom being resisted
in its descent by a given amount of friction, and in dispensing with the
rollers in coilers when these movable bottoms in the "cans" are used.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Robert Turner in the Great Seal Patent Office
on the 21st June 1870.
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 Twenty-third day of December, in the
year of our Lord One thousand eight hundred and sixty-nine, in the
thirty-third 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, TWISTING, OR SPINNING COTTON AND OTHER FIBROUS
MATERIALS," upon the condition (amongst others) that I, the said
Robert Turner, 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 Robert Turner, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement and the accompanying Drawings (that is
to say):-
My Invention relates to mechanism for twisting slivers or threads of

page_text: "can
"
fibrous material, and at the same time coiling the slivers or threads' so
twisted in a
or other similar receptacle, and it consists in a
modification and adaptation of the mechanism hitherto used for coiling
slivers in a "can," and forms a new combination and arrangement of
mechanism. The "can" or receptacle for the twisted sliver or thread is
mounted on a table or plate made to rotate at the speed required to give
the necessary twist and traverse for laying the coils. Above the "can"
a plate is arranged on an arm or arms from the end of a short hollow
vertical shaft in suitable bearings, this shaft being driven at such speed
as will give the twist required. On a suitable bracket secured to this
twist plate a pair of small rollers are mounted so as to propel the sliver
forward through a tube in the coiler plate, which is mounted to rotate
in the twist plate. The coiler plate is driven by a ring wheel resting on
the twist plate, and this ring is driven by an arm or arms from the end
of a short hollow shaft passing through the hollow shaft carrying the
twist plate. The small rollers are driven by gearing from the teeth upon
the coiler plate. Instead of the outer hollow short shaft carrying the
twist plate and the inner hollow short shaft driving the ring wheel, this
may be reversed; the inner short hollow shaft may carry and drive the
twist plate, and the outer shaft may drive the ring wheel. The sliver or
thread is brought from the rollers and passed down through the hollow
of the central shaft, then through the small rollers, then down the tube
of the coiler plate into the "can," which may have a speed so much
greater or less than the twist plate, as will give the required layer of
coils in the "can." Each twisting and coiling head may operate upon
a single sliver; but I prefer to bring two slivers to each head, and thus
while the required number of doublings of the sliver is obtained, fewer
"cans" or receptacles are required, and less labour and attention is
necessary, besides other advantages.
Fig. 1 is a vertical cross section; Fig. 2, a front elevation of my
improved combination and arrangement of twisting and coiling
mechanism; Fig. 3 is a plan section showing the twist plate coiler and
small rollers; Fig. 4, a top plan view; Fig. 5, an under side view of the
twist plate enlarged showing the clip for securing the "can;" Fig, 6 is
a cross section; and Fig. 7, a front view of the alternative mode of
mounting and driving the can.
a are the ordinary drawing rollers; b, part of roller beam; c, upper
rail; d, lower rail passing from end to end of the machine, and in these

page_text: rails the bearings of the two short hollow shafts for each head are formed;
e is the inner hollow shaft, it has a bearing at its upper end in the
rail c, and the lower end of it fits and works in the outer hollow
shaft (f), which has its bearing in the lower raid (d). The outer
hollow shaft (f) has two arms (f) on it, to the ends of which the twist
plate (9) is secured, and to the end of the inner hollow shaft (e) an
arm (e) is secured, which enters a notch in the ring wheel (h), which
fits in and rests upon the twist plate (g), as shewn. There is a bracket (i)
for each head secured to the roller beam (6), and these brackets carry a
shaft passing from end to end of the machine. The upper part of
each bracket (i) forms a stud, upon which are placed two spur wheels
and one bevel wheel, the lower spur wheel is fast to the bevel wheel,
which gears with one upon the shaft i. One spur wheel (e³) gears with
a wheel (e) on the inner hollow shaft, the other (f) with that (f) on
the outer hollow shaft (f). There are teeth on the edge of the coil
plate (k), which gear with the ring wheel (½), and the teeth on the coil
plate also gear with a wheel k¹ rotating on a vertical stud fixed in the
twist plate (9). The upper end of the boss of the wheel (k) carries a
bevel wheel which gears with one on the end of the shaft of one of the
small rollers (2); these rollers have bearings in a bracket (m) secured to
the twist plate (g). The two rollers are geared together by spur
wheels. The "can" (n) rests upon a sunk part in a table or
plate (p), as shown. There is a short stud or pin in the plate (p),
which enters a notch in the edge of the bottom of the "can," so that
the plate will drive the "can" round with it. The plate has the boss of
a bevel wheel (p') secured in it, which fits on a stud (g) that carries the
bearing of a shaft (r) passing from end to end of the frame, there being
a bevel wheel on this shaft which gears with the bevel secured to the
plate (p). The can plate rests upon three bevel antifriction pulleys 8,
which have bearings in adjustable boxes &¹, as shown. The "can
plate p may be carried entirely on a central spindle (p²) and driven by
skew bevel gear, as shown by Figs. 6 and 7. The twist plate (g) has a
cylindrical projection below it (see Fig. 5), one half of which is fast to
it, the other half (t) is hinged at (A), so as to open and allow the "can
to be placed and removed. The free end of the hinged part is made with
a tongue having a hook upon it, the tongue passes through a hole in
a part secured to the twist plate (9), and the hook takes hold of the
outside edge of the hole. The slivers from the rollers (a) pass over a
plate u resting on brackets (u³) attached to the roller beam, then down
35
"

page_text: the central tube (e) along a slanting spout (m³) carried by the bracket
(m). This spout may be made with its upper part open, and one side of
it higher than the other so as to catch the air in rotating and cause a
current to be propelled down the tube to the small rollers, and this helps
to carry the end of the sliver between the rollers at starting. After
passing through the rollers the sliver descends the tube secured to the
coiler plate and enters the "can." The drawing rollers and shafts j
and have to be geared with proper wheels with the main driving shaft
of the frame to make it complete, and this can be done by any skilled
mechanic.
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 general combination and arrangement of mechanism for
twisting slivers or threads, and coiling the same into a "can" or like
receptacle, substantially as herein-before described and illustrated by the
Drawings.
Secondly. The combination and arrangement of the mechanism for
twisting and coiling slivers or threads with the small rollers (1),
substantially as herein-before described and illustrated by the Drawings.
Thirdly. The system or mode of bringing two or more slivers from
the drawing rollers to one twisting and coiling head, as herein-before
described and shown in the Drawings.
In witness whereof, I, the said Robert Turner, have hereunto set
my hand and seal, this Twentieth day of June, in the year of
our Lord One thousand cight hundred and seventy.
