Improvements relating to the Rollers of Drawing Frames for Flax,
Hemp, Jute, and similar Fibres.
We, JAMES BARBOUR, Machinist, and SAMUEL MOODY, Worker in Leather, both
of Falls Foundry, Belfast, Ireland, do hereby declare the nature of this inven-
tion to be as follows:-
In drawing frames where great pressure is required on the drawing rollers
it is necessary to have an elastic medium on the pressing drawing roller; hitherto
it has been the custom to use leather on edge pressing rollers. Such rollers are
very expensive to make and wear out very rapidly having to be turned up
frequently to keep them in order, thereby reducing the diameter each time the
roller is turned up.
In our improved roller instead of fixing the leather to the roller we make
a leather sheet to cover the boss or face of the pressing roller, and long enough
to pass over a tension pulley carried at a distance from the roller.
As the roller revolves the sheet moves with it and when the sheet wears out
a new one is easily substituted thus the effective diameter of the roller is un-
changeable and on this account we can connect the two rollers by gearing and
thus obtain a positive motion.
By connecting the rollers by gearing less pressure is required on the drawing
rollers and we eliminate all tendency of the pressing roller to slip and thus we
obtain a far more effective pressing drawing roller than hitherto and at less
cost.
Any stretch that may take place in the leather sheet can be easily taken 'up
by adjusting the tension pulley.

-
In drawing frames where great pressure is required on the drawing rollers
it is necessary to have an elastic medium on the pressing drawing roller; hitherto
it has been the custom to use leather on edge pressing rollers. Such rollers are
very expensive to make and wear out very rapidly having to be turned up
frequently to keep them in order, thereby reducing the diameter each time the
roller is turned up.
In our improved roller instead of fixing the leather to the roller we make
a leather sheet to cover the boss or face of the pressing roller and long enough
to pass over a tension pulley carried at a distance from the roller.
As the roller revolves the sheet moves with it & when the sheet wears out
a new one is easily substituted thus the effective diameter of the roller is un-
changeable and on this account we can connect the two rollers by gearing and
thus obtain a positive motion.
By connecting the rollers by gearing less pressure is required on the drawing
rollers and we eliminate all tendency of the pressing roller to slip and thus we
obtain a far more effective pressing drawing roller than hitherto and at leas
cost.
Any stretch that may take place. in the leather sheet can be easily taken up
by adjusting the tension pulley.
Such being the nature and object of our said invention the following is a
complete description of same reference being had to the annexed drawings in
which Fig. I is an elevation of as much of a drawing frame as will shew the
nature of our said invention Fig. II is an end elevation of Fig. I.
At 1 is the drawing roller-2 being the pressing drawing roller. 3 is a leather
sheet passing over the face of pressing roller 2 & over tension pulley 4.
The pressing roller 2 is driven by means of a train of gearing from the draw-
ing roller 1, wheel 5 being fixed on the axle of roller 1, wheels 67 & 8 being
intermediate gearing into wheel 9 on shaft 10. A wheel 11 being fixed on this
shaft gearing into a wheel 12 which is fixed to the pressing roller 2. (This
wheel 12 may be cast on the pressing roller.)
By the use of these means we obtain a pressing drawing roller far more effective
than has hitherto been obtained & at less cost than hitherto.
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 general construction, combination & arrangement of pressing drawing
roller, as illustrated by drawings annexed & herein fully described.
(2) In pressing drawing rollers as described the combination of leather sheet
passing over face of pressing drawing roller & over tension pulley, & the driving
of the pressing drawing roller 2, by gearing from the drawing roller 1.
