Year: 1862

page_text: LETTERS PATENT to Thomas Critchley Barraclough, of the City of Man-
chester, in the County of Lancaster, Machine Agent, for the Invention
of "IMPROVEMENTS IN MACHINERY FOR SPINNING, TWISTING, AND ROLLING
TOBACCO." A communication from abroad by Mr. Ernst Breul, of
Hanover:
Sealed the 12th June 1863, and dated the 17th December 1862.
PROVISIONAL SPECIFICATION left by the said Thomas Critchley
Barraclough at the Office of the Commissioners of Patents, with his
Petition, on the 17th December 1862.
.I, THOMAS CRITCHLEY BARRACLOUGH, of the City of Manchester, in the
County of Lancaster, Machine Agent, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN MACHINERY FOR SPINNING, TWISTING, AND
ROLLING TOBACCO," to be as follows:---
This Invention consists in an apparatus hereafter described for spinning,
twisting, and rolling tobacco. I take one or more rectangular or other shaped
revolving frames or flyers, each provided with two pivots, one of which forms
a hollow trunnion for the tobacco to pass through as it comes from the feeder,
and the other carries a pair of driving pulleys, or other suitable mechanical
means for imparting rotary motion to the frame. Transversely to the revolving
axis of the frame, and within it, is fitted a spindle, which carries a bobbin, on
which the spun tobacco is rolled up. The bobbin is removed from the spindle

page_text: in order to strip the roll of tobacco from it, and for this purpose one of the
flanges is removed, which when the bobbin is at work is secured by screws
or otherwise to its spindle. The equal distribution of the tobacco on the
bobbin is effected by a guide travelling backwards and forwards parallel to the
. bobbin

SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Critchley Barraclough in the Great Seal Patent
Office on the 17th June 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
CRITCHLEY BARRACLOUGH, of the City of Manchester, in the County of Lan-
caster, Machine Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the 'Seventeenth day of December, in the year of
our Lord One thousand eight hundred and sixty-two, in the twenty-sixth
year of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Thomas Critchley Barraclough, Her special licence that
"I, the said Thomas Critchley Barraclough, my executors, administrators, and
assigns, or such others as I, the said Thomas Critchley. Barraclough, my
executors, administrators, or 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 SPINNING, TWISTING, AND ROLLING TOBACCO," (a communication to me from
abroad by Mr. Ernst Breal, of Hanover,) upon the condition (amongst
others) that I, the said Thomas Critchley Barraclough, my executors or
administrators, by an instrument in writing under my, or their, or one 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 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 Thomas Critchley Barraclough, 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, reference being had to the Drawings hereunto
annexed, that is to say:-

page_text: This Invention consists in an apparatus hereafter described for spinning,.
twisting, and rolling tobacco at one operation. I take one or more rectangular
or other shaped revolving frames or flyers, each provided with two pivots, one
of which forms a hollow trunnion for the tobacco to pass through as it comes
from the feeder, and the other carries a pair of driving pulleys or other suitable
mechanical means for imparting rotary motion to the frame. Transversely
to the revolving axis of the frame, and within it, is fitted a spindle, which
carries a bobbin, on which the spun tobacco is rolled up. The bobbin is
removed from the spindle in order to strip the roll of tobacco from it, and for
this purpose one of the flanges is removed, which when the bobbin is at work
is secured by screws or otherwise to its spindle. The equal distribution of the
tobacco on the bobbin is effected by a guide travelling backwards and forwards
parallel to the bobbin.
Figure 1 of the accompanying Drawings is an elevation, partly in section ;
Figure 2 an end view, and Figure 3 a plan of a revolving frame or flyer con-
structed according to this Invention. The frame or flyer is provided with two
pivots Land H, the pivot L forms a hollow trunnion, through which the tobacco
passes as it comes from the feeder, and the pivot H carries a pair of driving
pulleys n, m, through which rotary motion is imparted to the frame or flyer
by a driving band in the ordinary manner. Transversely to the axis of the
frame or flyer, and within it, is fitted a spindle D, which carries a bobbin,
on which the spun tobacco is rolled. The spindle D has its bearings in the
sides R, R, of the frame or flyer, and is so arranged that it can be lifted out
with the bobbin without interfering with the other parts of the frame or
flyer. The bobbin is formed of (say four sections, which when in the frame
are kept apart by screws h, h, at one end of the bobbin. In order to remove
the spun tobacco from the bobbin, take out the screws h, h, and take off the
flange E of the bobbin, when in consequence of the pressure of the tobacco
the sections, of which the bobbin is composed, being no longer kept apart
by the screws, will collapse or shrink, so that the tobacco becomes loosened,
and may be easily stripped off; z, z, are two arms screwed to the sides R, R,
of the frame or flyer, in which arms a shaft B cut with a double screw has
its bearings. A pin travels backwards and forwards in the screw of the shaft
B, and imparts motion to a guide piece K, in connection with which is a
roller F, round which the tobacco passes when it comes through the hollow
trunnion L, as indicated by the red lines in the Drawings, and as this roller
F, through the motion of the shaft B, travels backwards and forwards in front
of the bobbin, the spun tobacco is wound upon the bobbin regularly. The
roller F is supported by a shaft C fixed to the arms, 2; o is a groove!

page_text: pulley which transmits rotary motion to the spindle D, by means of a strap
or band, which passes over the pulley o, the guide rollers e, e, and the pulley
p on the spindle D; s is a grooved pulley, which transmits the motion to
another grooved pulley on the shaft B. The revolutions of the bobbin, as
compared with the revolutions of screw shaft B, must be regulated according
to the thickness of the tobacco to be spun. Figure 4 shews in front elevation
and Figure 5 in side elevation, both on a reduced scale, a flyer supported
in a frame together with the means of driving it from a treadle. I do not
however confine myself to this means of driving, as motion may be communi-
cated from any prime mover.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I claim as the "Improve-
ments in Machinery for Spinning, Twisting, and Rolling Tobacco," the
construction and employment of machinery consisting of a frame or flyer,
bobbin, and guide, acting in manner herein-before described to effect the
continuous and simultaneous spinning, twisting, and rolling of tobacco.
In witness whereof, I, the said Thomas Critchley Barraclough, have
hereunto set my hand and seal, this Thirteenth day of June, One
thousand eight hundred and sixty-three.
THOMAS CRITCHLEY BARRACLOUGH. (L.S.)
