PROVISIONAL SPECIFICATION.
Improvements relating to the Breaking, Cleaning, and Carding of
Tow Waste, Flax, Hemp, Jute, and similar Fibres.
We, ARTHUR TREDGOLD LAWSON, of Westwood Grange, Headingley, Leeds,
Engineer, FREDERICK WILLIAM LAWSON of The Oaklands, Adel near Leeds,
Engineer, and MARSHALL PORRITT.of Moor Lane, Gomersal, Spinner, do hereby
declare the nature of this invention to be as follows:-
The object of this invention is to break and card tow waste, and clean the same
from dust, dirt, and any other such foreign matter, and at the same time unravel,
break knots, noils or other tangled irregularities in flax, hemp, jute and similar
fibres to render the same fit for spinning purposes. To attain this object the
machine is provided with rollers covered with clothing and otherwise suitably
arranged to act upon the material. The machine is fed through a pair of fluted
rollers from a travelling sheet-the material is taken from the fluted rollers by a
feed roller and passed onto a cylinder by a stripper roller-sufficient space is
allowed between the feed roller and cylinder to permit any dust, dirt &c. to fall out
of the material, while passing from the feed roller to the cylinder.' The material
is next acted upon by a worker roller placed so as to work the material with the
stripper roller and cylinder. From the worker roller the material continues to pass
with the cylinder over to the doffer stripper-the use and action of this roller is to
catch on the regulated fibre from the cylinder and throw it down upon the doffer
roller. From the doffer roller the material is taken off by a knife or roller-the
treatment having now been completed.
If the material be of a very dirty, dusty & c. nature, the process may be continued
by repeating the treatment with another set of rollers from the doffer roller-the
doffer roller would in such a case become a feed roller to the second part of the
machine the other rollers would repeat the process already described.
The machine is shown by the drawing annexed.
A Travelling sheet.

B Fluted rollers
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
The combination of rollers and cylinders substantially as described and illus-
trated in the drawing for the cleaning of waste from materials such as flax, hemp,
jute and other similar fibres.
