County of York and Samuel Beaumont of Roubaix department du Nord
France, but temporarily of Leeds Yorkshire for an Invention of "IMPROVE-
PROVISIONAL SPECIFICATION left by the said John Charles Walker and
Samuel Beaumont at the Office of the Commissioners of Patents on the
21st February 1883.
JOHN CHARLES WALKER, of Shipley near Leeds in the County of York and
SAMUEL BEAUMONT of Roubaix department du Nord, France, but temporarily of
Leeds Yorkshire "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR CLEANING
WOOL,"
Our Invention has reference to treating the "burrs" and other foreign matter
for the purpose of freeing them from the wool, and to attain this end we provide
means as hereafter described whereby such burr or other foreign matter is broken
up or disintegrated. Our invention may be applied to wool carding or to other
wool preparing machines on which slivers are produced or employed.
According to our Invention, in a suitable position and as near as convenient to
the doffers or delivery rollers and transversely are placed two plates between
which the sliver is drawn.
38
For the purpose of disintegrating or breaking up the
burrs" or other foreign
matter we provide over the upper plate a bar, furnished with one or more rows of
pins projecting downwards. To this bar a vertical reciprocating quick movement
is imparted which causes the pins to pass through a longitudinal slot in the upper
plate and through the sliver, whilst such sliver is in motion. By this means the
pins pass through the "burrs" or other foreign matter and in so doing pierce and
break them up without interfering with or destroying the fibre of the wool.
These burrs or other foreign matter by such operation are so pierced that they are
readily removed in the ordinary succeeding operation.
When preferred another bar containing pins may be applied under the lower
plate of a similar construction to the one over the upper plate and operating in a
similar manner, also the apparatus may be placed at any desired angle, and the
reciprocating movement may be imparted from any suitable moving part of the
machine.

by the said John Charles Walker and Samuel Beaumont in the Great Seal
Patent Office on the 21st August 1883.
JOHN CHARLES WALKER of Shipley near Leeds in the County of York, and
SAMUEL BEAUMONT of Roubaix, department du Nord, France but temporarily of

"
Our Invention has reference to treating the "burrs" and other foreign matter
for the purpose of freeing them from the wool, and to attain this end we provido
inean's as hereafter described whereby such burr or other foreign matter is broken
up or disintegrated. Our invention may be applied to wool carding or to other
wool preparing machines on which slivers are produced or employed.
According to our Invention in a suitable position and as near as convenient to
the doffers or delivery rollers, and transversely are placed two plates between
which the sliver is drawn.
For the purpose of disintegrating or breaking up the ". burrs." or other foreign
matter we provide over the upper plate a bar, furnished with one or more rows of
pins projecting downwards. To this bar a vertical reciprocating quick movement
is imparted which causes the pins to pass through a longitudinal slot in the
upper plate and through the sliver, whilst such sliver is in motion. By this means
the pins pass through the "burrs" or other foreign matter and in so doing pierce and
break them up without interfering with or destroying the fibre of the wool.
These burrs or other foreign matter by such operation are so pierced that they are
readily removed in the ordinary succeeding operation.
:
When preferred another bar containing pins may be applied under the lower
plate of a similar construction to the one over the upper plate and operating in a
similar manner, also the apparatus may be placed at any desired angle, and the
reciprocating movement may be imparted from any suitable moving part of the
machine.
And in order that our invention may be more completely understood reference
is given to the accompanying drawings and to the letters and marks thereon
Fig 1 is a side elevation. Fig 2 is a transverse section. Fig 3 is a longitudinal
section of part of a carding machine shewing the application of our improvements
for cleaning wool.
In a suitable position and 'as near as convenient to the doffer a or delivery
roller b, and transversely within the framework c are placed the plates d and e;
their distance apart may be varied as required. Between these plates the sliver f
is drawn. Over the upper plate d we provide a bar g furnished with one or
more rows of pins h projecting, downwards: To this bar g is imparted a
vertical or radial reciprocating quick movement causing the pins / to pass through
a longitudinal slot in the upper plate d and through the sliver whilst such
sliver is passing between the plates d and e. By this operation the pins h pass
through the burrs or other foreign matter in the wool and in so doing pierce and
break them up without destroying the fibre. After this the burrs or other foreign
matter drop out or are removed in the succeeding operations.
•
When preferred an additional bar k furnished also with one or more rows of
pins may be applied under the lower plate e of a similar construction and
operating in the manner described to that of the upper bår.
$

page_text: The plates & and e also the bars g and k furnished with the pins may be placed
at any convenient angle to the machine. One way of giving motion to the bars g
and is the toggle arrangement operated through the connecting rod m froui
some convenient moving part of the machine.
Having now described the nature of our said Invention and described with the
aid of drawings how the same may be carried into practice we would have it
understood that we do not limit ourselves to the precise details or configuration
of the parts we have described and shewn as the same may be varied or modified
without departing from the nature of our said Invention; what we do claim is :-
The arrangement and application of the plates d and in combination with
.the bar g or bars g and k furnished with pins h and arranged and operating
substantially as and for purposes herein set forth.
In Witness whereof L. the said John Charles Walker, for myself and
on behalf of the said Samuel Beaumont have hereunto set my hand and
seal this (1st) first day of August in the year of our Lord One thousand
eight hundred and eighty three.
JOHN CHARLES WALKER. (L.S.)
