IMPROVE- MENTS IN MACHINERY OR APPARATUS TO BE EMPLOYED IN PREPARING COTTON OP AT A SHRA COL"
Year: 1870

page_text: LETTERS PATENT to Alexander Barlow and John Taylor, both of
Bury, in the County of Lancaster, for the Invention of "IMPROVE-
MENTS IN MACHINERY OR APPARATUS TO BE EMPLOYED IN PREPARING COTTON
OP AT A SHRA
COL"
PROVISIONAL SPECIFICATION left by the said Alexander Barlow and
John Taylor at the Office of the Commissioners of Patents, with
their Petition, on the 2nd April 1870.
We, ALEXANDER BARLOW and JOHN TAYLOR, both of Bury, in the
County of Lancaster, do hereby declare the nature of the said Invention
for " IMPROVEMENTS IN MACHINERY OR APPARATUS ΤΟ BE EMPLOYED IN
PREPARING COTTON OR OTHER FIBROUS SUBSTANCES FOR SPINNING," to be as
follows:-
The object of this Invention is to dispense entirely with the use of the
slubbing frame, and to deliver the slivers from the drawing frame into
cans in such a state that they may be taken direct from the drawing
frame to the roving frame, and by these means not only are the slubbing

page_text: frames dispensed with, but as the cans each contain about six times as
great a length of sliver as the bobbins or spools, the roving frames will
not require to be stopped so often and may be run much faster, and thus
a great economy in time as well as labor is also effected.
In carrying out our Invention we take an ordinary drawing frame and
at a convenient distance in front of the front drawing rollers we arrange
a series of short tubes (one for each sliver) in such a way that the tubes
are capable of revolving whilst the slivers pass through the centre, the
said tubes being caused to revolve rapidly by means of an endless strap
or band passing round and driven by a pulley which receives its motion
from the main driving shaft or any other convenient shaft of the frame.
These tubes are not drilled through their entire length, but are solid at
the end furthest from the drawing rollers, and the slivers pass out
through a transverse hole at one side and then through another trans-
verse hole near the end, which latter is pointed and delivers the sliver
between a pair of calendering rollers. Each pair of slivers is carried
quite round the top calendering roller and then the two are doubled
together by being again passed through the rollers at a point, midway
between where they passed through the first time, and they are then
delivered in this doubled state into the revolving cans which are placed
beneath. Instead of passing the two slivers twice through the rollers to
double them as above described they may pass only once through and
then through a guide to a second pair of calendering rollers which effects
the doubling. The false twist which is put into the slivers in passing
through the revolving tubes condenses the fibres, and the calendering
rollers consolidate and harden the same, and although little or no real
twist is put in yet the slivers from the revolving cans may be taken
direct to feed the roving frames, and will make in all respects as
good a roving as has heretofore been made with the help of the slubbing
frame.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Alexander Barlow and John Taylor in the Great
Seal Patent Office on the 1st October 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, ALEXANDER
BARLOW and JOHN TAYLOR, both of Bury, in the County of Lancaster, a
send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Second day of April, in the year of our
Lord One thousand eight hundred and seventy, in the thirty-third year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto us, the said Alexander Barlow and John Taylor, Her special licence
that I, the said Alexander Barlow and John Taylor, our executors,
administrators, and assigns, or such others as we, the said Alexander
Barlow and John Taylor, our 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 OR APPARATUS TO BE EMPLOYED IN PREPARING
COTTON OR OTHER FIBROUS SUBSTANCES," upon the condition (amongst others)
that we, the said Alexander Barlow and John Taylor, our executors or
administrators, by an instrument in writing under our, or their, or onc
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 Scal Patent
Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that we, the said Alexander Barlow and Jolin
Taylor, 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 and accompanying
Drawings (that is to say) :-
The object of this Invention is to dispense entirely with the use of
the slubbing frame and creels, and to deliver the slivers from the drawing
frame into cans, in such a state that they may be taken direct from
the drawing frame to the roving frame, and by these means not only
are the slubbing frames dispensed with, but as the cans cach contain
about six times as great a length of sliver as the bobbins or spools,
the roving frames will not require to be stopped so often and may be run
much faster, and thus a great economy in time as well as labor is also
effected.
The usual practice in cotton spinning is to take the sliver from tho
drawing frame in cans and to run the same up at the slubbing frame in
single ends on the bobbins; the bobbins being then taken and placed on

page_text: creels on the intermediate frame or roving frame, are again drawn and
doubled before being taken to the twisting or spinning machine; the
object of these various processes being to reduce the thickness of the
sliver and to get the requisite doubling to make an even thread.}
By the use of our improvements we are enabled to reduce the drawing
sliver to the thickness of a slubbing or intermediate thread with apparent
twist in and to put two or more threads into one can, instead of winding
them on to bobbins; we attach great importance to the running or
doubling of two condensed threads or slivers into one can after passing
the draw rollers, by which we secure the requisite strength for lifting or
drawing from the bottom of the cans.
In carrying out our Invention we take an ordinary drawing frame,
and at a convenient distance in front of the front drawing rollers we
arrange a series of short tubes (one for each sliver) in such a way that
the tubes are capable of revolving whilst the slivers pass through the
centre, the said tubes being caused to revolve rapidly by means of an
endless strap or band passing round and driven by a pulley which
receives its motion from the main driving shaft or any other convenient
shaft of the frame. These tubes are similar to what are known as
dyer's tubes," and are not drilled through their entire length but arc
solid at the end furthest from the drawing rollers, and the slivers pass
out through a transverse hole at one side and then through another
transverse hole near the end, which latter is somewhat pointed and
delivers the sliver between a pair of calendering rollers. Each pair of
slivers is carried quite round the top calendering roller, and then the
two are doubled together by being again passed through the rollers at a
point midway between where they passed through the first time, and
they are then delivered in this doubled state into the revolving cans
which are placed beneath. Instead of passing the two slivers twice
through the rollers to double them as above described they may pass
only once through and then through a guide to a second pair of
calendering rollers which effects the doubling. The false twist, which is
put into the slivers in passing through the revolving tubes condenses the
fibres, and the calendering rollers consolidate and harden the same, and
although little or no real twist is put in, yet the slivers from the re-
volving cans may be taken direct to feed the roving frames, and will
make in all respects as good a roving as has heretofore been made with
the help of the slubbing frame.

page_text: Such being the nature and object of our said Invention for "Im-
provements in Machinery or Apparatus to be employed in Preparing
Cotton or other Fibrous Substances," we will now proceed to describe
more in detail the manner in which the same is to be or may be per-
formed or carried into practical effect, and in order that the same may
be clearly understood we have hereunto annexed a Sheet of Drawings
illustrative thereof, and have marked the same with figures and letters
of reference corresponding with those in the following explanation
thereof.
In the annexed Drawings Fig. 1 is a sectional view of a drawing
frame with our improvements shown as applied thereto, and constituting
what may be called a "duplex drawing and slubbing frame;" Fig. 2 is
a front view; and Fig. 3 a plan view of the same.
a, a, is the frame; b, b, the drawing rollers; and c, c, the revolving
tubes, one of which is shown full size at Fig. 4. These tubes as before
described, are driven rapidly by means of an endless strap or band
passing alternately over one and under the next, as shown by the dotted
lines in Fig. 2, the said strap or band passing round and being driven
by a pulley which receives its motion from any convenient driving
shaft; d, d, are a pair of calendering rollers; e, e, a condensing
roller; ff, the "coiler head;" and 7, 9, the cans.
It will be seen that in Figs. 1, 2, and 3 the slivers pass singly between
the condensing roller c, e, and one of the calcudering rollers d, d, then
two together through a countersunk hole in a guide plate h, h, and
thence in a doubled state between the pair of calendering rollers d, d, to
the coilcr.
Instead of this arrangement, however, that shown at Fig. 5 may be
adopted, wherein each thread passes singly between the calendering
rollers, then quite round the upper one, and finally the two pass through
the rollers together midway between the points where they passed
through the first time.
It will be observed that we dispense entirely with the creels and
bobbins, and substitute in their place coiler cans g, g, of six or seven
inches in diameter, which we place at the back of the roving frame,
which cans when properly filled will last five or six days, thus saving
the time occupied in crecling and removing all obstruction to the light,
besides making the card room more healthy for the workpeople and
saving a large amount of "fly.”

page_text: Having now described the nature and object of our said Invention,
together with the manner in which the same is to be or may be per-
formed or carried into practical effect, we wish it to be understood that
we claim as our Invention,-
Firstly. The general combination and arrangement of the machine
forming a "duplex drawing and slubbing frame," substantially as herein
before described.
Secondly. The doubling of two or more ends or slivers together in the
drawing frame after passing through the drawing rollers and running
the same through a guide plate into a can.
And, thirdly. The use of the "dyer's tube," in combination with two
or more condensing or calendering rollers, substantially in the manner
and for the purposes herein-before set forth.
In witness whereof, we, the said Alexander Barlow and John
Taylor, have hereunto set our hands and seals, this Twenty-
seventh day of September, in the year of our Lord One thousand
eight hundred and seventy.
