Year: 1873

page_text: LETTERS PATENT to William Macargur Scott, of 23, Arthur Street,
Belfast, in the County of Antrim, Ireland, for the Invention of
Sealed the 7th November 1873, and dated the 28th May 1873.
PROVISIONAL SPECIFICATION left by the said William Macargur Scott
at the Office of the Commissioners of Patents, with his Petition, on
the 28th May 1878.
I, WILLIAM MACARGUR SCOTT, of 23, Arthur Street, Belfast, in
the County of Antrim, Ireland, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN MACHINERY FOR SPINNING TOBACCO," to
be as follows:-
:-
This Invention has for its object improvements in machinery for
spinning tobacco. For this purpose I employ two cylinders or drums,
or one drum and one cylinder revolving the one within the other in
opposite directions and with similar surface speeds. The drums or
cylinders or cylinder and drum rotate in vertical planes making an

page_text: angle the one with the other. The twist or plug of tobacco as it is
prepared by the attendants passes between the two drums or cylinders or
cylinder and drum, and on entering between which it receives its cover
or wrapper when partly under pressure between the two surfaces and
is then rolled and consolidated between them. The twist or plug of
tobacco thus produced is sent forward by their combined action to a reel
mounted in a frame which is caused to revolve, and in this way the twist
or plug of tobacco is wound upon the reel, the reel possessing the
necessary directional motion for this purpose. The two drums or
cylinders or cylinder and drum are placed in a convenient position on
the top of the table to suit the operating attendants. The inner cylinder
or drum is driven by bevelled gear and the outer is driven either by spur
gearing or by a belt passing around it. The outer drum or cylinder is
held in a ring or collar and which can be raised by the hand to the
requisite height for inserting the twist or plug when commencing the
work or after taking away the full reel. The working faces of the
drums or cylinders or cylinder and drum are convex and concave, or
they may form towards each other parallel horizontal surfaces that they
may pass the work between them in a direct line from the operating
attendants on to the reel.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Macargur Scott in the Great Seal Patent
Office on the 27th November 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
MACARGUR SCOTT, of 23, Arthur Street, Belfast, in the County of Antrim,
Ireland, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth 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 William Macargur Scott, Her special license that
I, the said William Macargur Scott, my executors, administrators, and
assigns, or such others as I, the said William Macargur Scott, my execu-
tors, administrators, and assigns, should at any time agree with, and no

page_text: 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 TOBACCO," upon the condition (amongst others)
that I, the said William Macargur Scott, my executors or adminis-
trators, 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 William Macargur Scott, 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 has for its object improvements in machinery for
spinning tobacco. For this purpose I employ two cylinders or drums,
or one drum and one cylinder revolving the one within the other in
opposite directions and with similar surface speeds. The drums or
cylinders or cylinder and drum rotate in vertical planes making an angle
the one with the other. The twist or plug of tobacco as it is prepared
by the attendants passes between the two drums or cylinders or cylinder
and drum, and on entering between which it receives its cover or
wrapper when partly under pressure between the two surfaces and is
then rolled and consolidated between them. The twist or plug of
tobacco thus produced is sent forward by their combined action to a reel
mounted in a frame which is caused to revolve, and in this way the
twist or plug of tobacco is wound upon the reel, the reel possessing the
necessary directional motion for this purpose. The two drums or
cylinders or cylinder and drum are placed in a convenient position on
the top of the table to suit the operating attendants. The inner cylinder
or drum is driven by bevelled gear and the outer is driven either by spur
gearing or by a belt passing around it. The outer drum or cylinder is
held in a ring or collar and which can be raised by the hand to the
requisite height for inserting the twist or plug when commencing the
work or after taking away the full rcel. The working faces of the drums
or cylinders or cylinder and drum are convex and concave that they may

upon
a, a, is the frame of the machine, and 6 is an axis mounted in bearings
upon it; b¹ is a belt pulley by which the axis is driven where the pulley
is made fast with the axis by means of a friction clutch; c is the clutch
lever; 62 is a worm on the axis 6 driving the worm wheel d¹ the
transverse horizontal axis d. From the axis d by one pair of bevelled
pinions the vertical axis e is driven, and by another pair the vertical
axis f; similarly the axes e and frespectively drive the horizontal axes g
and h. On the axis g the drum i is fixed; this drum is contained within
the cylinder k, and it is by being rolled between the outer surface of the
drum and the inner surface of the cylinder that the twist or plug of
tobacco is consolidated and spun. The cylinder k is held and rotates
within a ring k³, it receives its motion from an endless band passing
around it and also encircling a belt pulley upon the axis h; this ring k
is fixed to an arm k* which is able to turn freely upon the axis h; k³ is
a handle connected with the ring k¹ by which the workman is able to
raise and lower the cylinder k and regulate the pressure upon the work.
The ring and parts connected therewith are shewn separately at
Figure 4; k is a weight connected with the ring ; is the reel on
which the tobacco twist is wound, it is mounted upon an axis which is
carried in a frame m. This frame is supported in bearings on the main
frame, in which it is able to turn, and it is driven by a belt passing to a
belt pulley m¹ upon it from a belt pulley on the axis b. The reel ?
receives rotary motion to cause it to wind up the tobacco twist by means
of an endless cord n which passes around a pulley on the axis of the
reel over guide pulleys o, o, to a pulley p which is mounted so as to be
able to turn on the neck of the frame m.
The pulley p is provided with
a flange encircled by the brake ring or clip p¹ which is held from

page_text: rotating and is regulated in its pressure upon the flange of the pulley by
means of a screw. In this way the pulley p is retarded and caused to
lag, and motion is given to the cord n which it transmits to the reel /
and causes it to wind up the work; q is a table at which the attendants
stand; one of them prepares a continuous core and another applies to
the core the covering strips and regulates the passage of the twist or
plug into and between the surfaces i and k. After issuing from between
these surfaces the twist passes through the neck of the frame m which is
tubular, and it is wound upon the reel 1; r is a rod connected with the
clutch lever c and also with treadles, by depressing and liberating which
the machine can be instantaneously started and stopped.
Having thus described the nature of my said Invention, and the
manner of performing the same, I would have it understood that I
claim as my improvements in machinery for spinning tobacco,-
1st. The arrangement of drums or cylinders i and k, substantially as
described.
2nd. The combination of machinery, substantially as described.
In witness whereof, I, the said William Macargur Scott, have here-
unto set my hand and seal, this Seventeenth day of November
in the year of our Lord One thousand eight hundred and seventy-
