page_text: LETTERS PATENT to Isaac Crowther Watson of Leeds in the County of
York for an Invention of IMPROVEMENTS IN MACHINES FOR DISINTEGRATING
WOOLLEN OR OTHER WOVEN FABRICS
PROVISIONAL SPECIFICATION left by the said Isaac Crowther Watson at
the Office of the Commissioners of Patents on the 16th October 1882.
ISAAC CROWTHER WATSON of Leeds in the County of York "IMPROVEMENTS
IN MACHINES FOR DISINTEGRATING WOOLLEN OR OTHER WOVEN FABRICS."
The object of my improvements is to disintegrate or separate the fibres of woven
fabrics in such a manner that they may be re-spun into thread to be used as required
for manufacturing purposes, and by these improvements I am enabled to obtain
much longer fibres than in machines hitherto used for the above purpose,
consequently there are much less breakages in re-spinning than when the shorter
fibres obtained by other machines are employed.
For the above purpose I mount a cylinder between suitable framework and
cover it with carding or filleting having hooked or curved teeth, as the cylinder is
caused to revolve these teeth are so arranged that they pass with their points into
the material as it is fed to them, by fluted feed rollers. By the teeth passing into
the material in the above manner the fibres are drawn away instead of being
rubbed or torn away in the ordinary machines, consequently the fibres produced by
my improvements are much longer.
I employ a rapidly revolving brush at the back of the machine for removing the
fibres from the teeth of the cylinder.

page_text: Fig 1 is a front elevation and Fig 2'n plan looking at the top shewing arrange-
ment of a machine constructed in accordance with my Improvements Fig 3 shews
a. modification in the arrangement of part of the machine to be described
hereafter.
In Figs 1 and 2 a is the framework of the machine on it in bearings bis
mounted the cylinder c which is covered with carding or filleting having hooked or
curved teeth as shewn. As the cylinder cis caused to revolve by some convenient
motor, the curved or hooked teeth are so arranged that they pass with their points'
into the material as it is fed to them by the fluted rollers d d. These are also
carried in bearings a and on the framework a. The upper fluted roller d' is.
pressed down upon the lower roller d by the weighted levers ff, springs, screws or
their equivalents
The required motion is imparted to the fluted rollers & and d¹ from the driving
pulley on the cylinder shaft h, thence through pulley on the stud and spur
gearing. Motion is imparted to the cylinder c through the driving pulley m and
spur gearing n. In order to remove the fibres after being taken up by the teeth
on the revolving cylinder c 1 employ a rapidly revolving brush o mounted in
bearings fixed on the framework a The required motion is transmitted thereto
from the pulley 7 on the cylinder shaft, thence by cords or belting through the
pullies 7 and 8 on the stud t to the pulley on the brush shaft y
The material is fed to the machine by means of an ordinary travelling sheet on
the rollers wand carried by bearings in the framework . Motion is imparted.
thereto from the fluted roller & through the pullies y and zor gearing.
A modification in the arrangement for disintegrating or separating the fibres is.
shewn at Fig 3. In this arrangement I employ a pair of carded or filleted rollers

page_text: 1 and 2 having hooked or curved teeth between the large carded or filleted
cylinder 3 and the feed rollers d d. In this arrangement the large carded or
filleted cylinder 3.is employed for stripping these rollers 1 and 2 and also for
completing the disintegration of the fibres. In this arrangement also I employ
the quickly revolving brush o as and for the purpose described for the arrangements
in Figs 1 and 2
Having now described the nature of my said Invention and shewn by the aid of
drawings how the same may be carried into practice I would have it understood
that I do not limit myself to the precise details and configuration of the parts I
have described and shewn as the same may be varied or modified without in any
way departing from the nature of my said Invention, but what I do claim is :-
The general arrangement construction and combination of the various parts
forming the machine for disintegrating woollen or other woven fabrics and mere
modifications of the same substantially as and for the purposes herein set forth.
In Witness whereof I the said Isaac Crowther Watson have hereunto set my
hand and seal this tenth day of April in the year of our Lord one thousand
eight hundred and eighty three.
