IMPROVEMENTS IN MACHINES FOR SPINNING OR TWISTING TOBACCO
Year: 1884

page_text: We, ADAM CALDOW, and JAMES BURNETT, both of London Road, Kilmarnock, in
the County of Ayr, Brassfounders, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN MACHINES FOR SPINNING OR TWISTING TOBACCO ;" to
be as follows:-
This Invention relates to improvements in machines for spinning or twisting
tobacco.
The improved machine comprises a pair of rolls which are carried in bearings in
a framing, so that their axes are inclined to each other, and which are fitted to roll
on each other. The rolls are hollowed out so that when rolling together they
present a continuous bearing surface on which the tobacco may rest while being
spun or twisted. Over the two skewed rolls is placed a small pressing roller which
bears on the upper surface of the tobacco to keep it in close contact with the skew
rolls. The rolls are driven by means of pinions on the ends of the roll spindles, or
by other suitable gearing. The rolls are tapered so that the tobacco, which is fed
in between the rolls at their smaller end, is acted on by the surface of the rolls at a
greater circumferential speed as 'it travels through between them. The action of
the skew rolls on the tobacco passed in between them is to form it into a strand or
rope, and the effect of tapering the rolls is to impart a greater degree of twist to
the strand or rope at the end where it' is discharged from the rolls. The improved
machine may be combined with the usual apparatus for drawing off the twisted
strand of tobacco and rolling it into coils.

page_text: We, ADAM CALDOW and JAMES BURNETT, both of London Road, Kilmarnock,
in the county of Ayr, Brassfounders, do hereby declare the nature of our said
Invention for "IMPROVEMENTS IN MACHINES FOR SPINNING OR TWISTING TOBACCO,"
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
In the accompanying Drawings, Figure 1 is an elevation and Figure 2 a plan of
our improved tobacco spinning or twisting machine. The improved machine
comprises a pair of rolls A, A, which are carried in bearings bb in a framing B, so
that their axes are inclined to each other, and which are fitted to roll on each other.
The rolls A. A are hollowed out so that when rolling together they present a con-
tinuous bearing surface on which the strand of tobacco C may rest while being
spun or twisted. Over the two skewed rolls A A is placed a small pressing
roller A which bears on the upper surface of the tobacco C to keep it in close
contact with the skew rolls. This roller A¹ is pressed down on the skew rolls A A
by a weighted lever D which is centred on one of the brackets B, so that the lever
can be turned over to raise the roller A¹ out of contact with the tobacco. Instead
of the weighted lever, a spring or springs may be used to retain the roller A¹ in
place. The rolls A A are driven by means of pinions E fixed on the ends of the
roll spindles or on the ends of the roller actuated by a pinion E driven through
gearing E from the spindle F. The rolls A A are tapered so that the tobacco,
which is fed in between the rolls at their smaller end, is acted on by the surface of
the rolls at a gradually increasing circumferential speed. The action of the skew
rolls A A on the tobacco, which is rolled by hand on the board G and passed in
between them is to form it into a strand or rope, and the effect of tapering the rolls
is to impart a greater degree of twist to the strand or rope at the end where it is
discharged from the rolls. The improved machine may be combined with the usual
apparatus for drawing off the twisted strand of tobacco and rolling it into coils.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is,―
1. The combination of parts forming the improved tobacco twisting or spinning
machine herein described and illustrated.
2. The arrangement of the rotating skew rolls for rolling and twisting or spinning
tobacco, substantially as herein described and illustrated.
