Improved Driving Mechanism for the Revolving Rubbers of
Drawing Frames.
JAMES BARBOUR, Machine Maker, & FRANCIS THOMAS NAYLOR, Draughtsman,
both of Falls Foundry, Belfast, do hereby declare the nature of this invention to be
as follows:-
This improvement relates to drawing frames for flax hemp & similar fibres in
which it is necessary to use revolving rubbers on the retaining rollers for the
purpose of keeping them clean & free from loose fibres & dust, and consists in
driving the rubber direct from the roller which is to be cleaned by means of a pinion
on end of said roller which gears direct into an internal wheel fastened to the
revolving rubber.
By these means we get the necessary slow speed & right direction of rotation of
rubber without using the train of spur wheels which has hitherto been necessary to
obtain the slow speed & right direction of rotation.
The drive is self contained, the internal wheel forms a cover for the driving pinion,
fewer parts, are used thereby simplifying the construction & increasing the
efficiency of the rubbers.

in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-

fewer parts are used thereby simplifying the construction & increasing the efficiency
of the rubbers.
Such being the nature & object of our invention the following is a complete
description of same reference being had to the accompanying sheet of drawings in
which Fig. I shews as much of a drawing frame as will shew the nature of our
invention Fig. II is a plan view of Fig. I.
1 & 2 are the retaining rollers 3 & 3 the revolving rubbers 4 & 4 are pinions fixed
to the ends of the retaining rollers these pinions gearing direct into the internal
wheels 5 & 5 which are fixed to the rubbers 3, 3.
By the use of these means each retaining roller drives its own rubber at a slower
speed & with fewer parts than hitherto thereby simplifying the construction &
increasing the efficiency of the rubbers.
Having now particularly described. &
& in what manner the same is to be
claim is :-
ascertained the nature of our invention
performed, we declare that what we
The driving of revolving rubbers direct from the roller to be cleaned by the rubber :
by means of a pinion fixed to the roller & gearing direct into an internal wheel
fastened to the revolving rubber.
