PROVISIONAL SPECIFICATION.
Improvements in Breaking and Pulling Machines for Breaking and
Opening Cotton and other Textile Materials.
I, JOHN MCQUEEN, of John Hetherington and Sons Limited, of Vulcan Works,
Pollard Street, Manchester, in the County of Lancaster, Machine Maker, do
hereby declare the nature of this invention to be as follows:- -
My invention relates to improvements in breaking and pulling machines for
breaking and opening cotton and other textile materials in which the rollers in
each pair are driven at the same speed but each successive pair of rollers is driven
at an increased speed and my improvements consist essentially in dispensing
with the ordinary breaking or pulling rollers and in substituting therefor a series
of pairs of concavo-convex rollers, that is to say, one roller in each pair has a
concave and the other roller has a convex surface. The rollers may be constructed
in any convenient and suitable way as for example, they may be built up by
threading on to an axle a series of discs or rings of varying diameters (and with
spiked, serrated, fluted or otherwise suitably prepared surfaces) in order to obtain
the required convex or concave form on the surface of the completed roller.
Datel this 10th day of March 1898.

I, JOHN MCQUEEN, of John Hetherington and Sons Limited, of Vulcan Works,
Pollard Street, Manchester, in the County of Lancaster, Machine Maker, do
hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-

the required convex or concave form on the surface of the completed roller.
In the accompanying sheet of drawings—
Figure 1 is a sectional elevation of part of a breaking and pulling machine
constructed according to my improvements.
Figure 2 is a plan of the top row of rollers and Figure 3 is a plan of the lower
row of rollers.
In these views, A designates the convex and B the concave breaking or pulling
rollers and CC the pair of fluted delivery rollers of which the lower roller C¹ is
recessed to receive the projecting teeth of the lower concave pulling roller B.
The concavo-convex rollers AB are shown built up of a series of serrated discs
of varying diameters d threaded on axles and spaced by collars but the sur-
faces of the discs d may be spiked, fluted or otherwise suitably prepared; and
further the rollers AB instead of being built up of discs may be constructed in
any other convenient way.
I find that three pairs of concavo-convex rollers AB give good results, but four
or any other suitable number of pairs may be employed.
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:
In a machine for breaking and pulling cotton and other textile materials the
construction, use and application of a series of pairs of concavo-convex breaking
and pulling rollers substantially as herein set forth.
