JAMES GORDON of 41 Bridge Street Ballymena in the County of Antrim,
Ireland Mill Manager do hereby declare the nature of my invention for AN
IMPROVED METHOD OF DRIVING REVOLVING RUBBERS, CONNECTED WITH THE
RETAINING ROLLERS OF MACHINERY FOR PREPARING FLAX & THE LIKE to be as
follows:-
This invention consists of a novel method of driving revolving rubbers when
attached to the double retaining rollers of flax preparing machinery in which the
retaining power is obtained by passing the material to be drawn over a jockey
roller revolving above and between and in contact with the two retaining rollers.
This method of driving consists simply in fixing suitable toothed wheels on the
ends of the jockey rollers and geering them into wheels on the ends of the revolving
rubbers which are thus caused to rotate in the required direction.
By this means of driving the rubbers each head of the frame is complete in itself
and any one rubber can be taken out without interfering with or stopping any
other rubber in the frame.

roller revolving above and between and in contact with the two retaining rollers.
This method of driving the revolving rubbers for retaining rollers of flax
machinery will be understood from the following description reference being made
to the drawing, herewith in which the same letters and figures of reference always
apply to the same or like parts
Fig. 1. is a section of so much of an ordinary flax drawing frame as is necessary
to shew the relative positions of the retaining rollers and revolving rubbers.
Fig. 2 is a top view of part of a head or section of a frame to shew that each
head has an independent driving arrangement.
This method of driving consists simply in fixing suitable toothed wheels (a¹) on
the ends of the jockey rollers (a) and geering them into wheels (c') fixed on the
ends of the revolving rubbers (c) which are thus caused to rotate in the required
direction.
The surfaces of the retaining rollers (b) and of the revolving rubbers (c) which
are in contact move in opposite directions as indicated by the arrows.
The revolving rubbers (c) are covered with cloth or felt in the usual manner.
By this arrangement of driving the revolving rubbers (c) of retaining rollers (b)
each head of the frame is complete in itself and any one rubber (c) can be taken
out for the purpose of cleaning or examination without interfering with or stopping
any other rubber in the frame.
The position of these revolving rubbers (c) is practically the same as the dead
rubbers hitherto. used for keeping the retaining rollers clean so that revolving
rubbers driven in this manner can be readily applied to existing machines the
slots (d) required for the dead rubbers forming the guides for the pivots (c²) of
the revolving rubbers.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
The arrangement described for driving revolving rubbers in separate of inde-
pendent heads by means of the jockey rollers.
