We, THOMAS HALL and JOHN BEGG MOKERROW, of Pendleton, in the
County of Lancaster, Manufacturers, and THOMAS RAMSDEN SHAW, of
the same Place, Manager, do hereby declare the nature of the said
Invention for "IMPROVED MEANS FOR EFFECTING THE REMOVAL OR DISCHARGE OF
DYE-WOOD FROM HANKS OR YARN," to be as follows:-
Our Invention relates principally or more particularly to the treatment
of those hanks of cotton or other yarn or thread which have been dyed
by means of barwood. The interstices between the fibres of yarn dyed
as aforesaid are to a great extent occupied by a fine dust, consisting of
small particles of the dye-wood, and previously to our Invention the
said dust has been removed after the yarn has been dried by shaking
each hank by hand, the said operation being tedious and unpleasant, and
to some extent unhealthy.
Now our Invention has for its object to render the said operation less
unpleasant to the operator, and also to effect the discharge of the said

page_text: dye-wood more fully than is usual, and to this end we employ an
apparatus to shake the said hanks, which said apparatus may be enclosed
during the operation of shaking, so as to prevent as near as may be the
discharge of the dust therefrom, except through a passage or passages
provided for the removal of the said dust, a current or currents of air
being caused to flow out of the apparatus, and into the said passage or
passages, the said dust or the greater part thereof being thereby
conveyed any desired distance away from the apparatus. In the form
of apparatus which we have found to be suitable we loop each hank on a
pair of large bobbins, and we prefer to arrange a number of such pairs of
bobbins in each apparatus so as to be able to operate upon several hanks
at one time. One bobbin in each pair is mounted on the end of a spring
lever, the other end of the said lever being attached to a rocking shaft or
bar to which a quick vibrating motion is imparted by means of cranks or
excentrics on the main driving shaft. The other bobbin in each pair is
caused to revolve by means of a worm fixed on a revolving shaft, and
gearing with a worm wheel fixed or formed on the bobbin, or other
means may be adopted as found to be suitable. Underneath the hanks
are two or more inverted funnels, the lower ends of which are in com
munication with the aforesaid air passages, and the said passages
communicate with a fan or with other means for causing the air to flow
from the interior of the apparatus and into and through the said
passages. When the apparatus is supplied with hanks and set in motion
the action of the vibrating bobbins shakes the said hanks, and the
revolving bobbins cause the said hanks to circulate around the said
bobbins, in order that all portions of the said hanks may be subjected to
the shaking action, the dust discharged by these means being carried
away from the apparatus in manner as aforesaid.
The apparatus as herein described may be considerably modified
without departing from the principle of our Invention.
