Improvements in Mechanism for Cleaning or Removing the Burrs,
Thorns, and other Impurities from Wool, Cotton, and other
Fibrous Substances.
I, JULES DÉSIRE MOREL, 166, Rue Pellart, Roubaix, France, Manufacturer,
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 :-
This invention has for its object to cleanse wool, cotton, and other staple from
the burrs, thorns and other impurities contained therein before entering the
carding or other similar machine.
This effect by means of the mechanism illustrated in the accompanying
drawings, wherein Figures 1, and 2, are detail views in section and plan of the
drum catcher hereafter described, and Figure 3 is a view shewing the general
arrangement of such mechanism.
C is a drum catcher consisting of a series of discs a, a¹ mounted on a central
spindle their external edges & presenting the form of a flat pulley. Suitable division
plates d are fixed between such discs so as to leave more or less space between such
edges the width of such space being regulated by the thickness of the division
plates. Annular projections f. f are formed on such edges having on their
peripheries small oblique grooves g.
The interstices between the annular projec-
tions are too small and the oblique grooves g too narrow to admit of any foreign
substances passing between them. Rotary motion is imparted to the drump in any
convenient and well known manner. The wool or other fibrous substance to be
cleaned is brought by an endless apron A to the feed rollers B. B¹ B² B³ the
teeth whereof are placed in a contrary direction to that of their travel, so as to
retain the impurities eliminated from the staple by the action of the drum catcher.
After the wool or other staple has passed between the feed rollers B B³ it remains
pendent, but is immediately caught up by the drum catcher which carries it
towards the feed roller B. At this moment the filaments retained by B³ and
carried forward by the drum C, (the rotation whereof is relatively very rapid,)
enter the interstices between the annular projections f. f and rest on the peripheries
of the division plates d. The feed rollers B. B' B2 B3 are mounted on axes having
a to and fro motion which is imparted thereto in any convenient and well known
manner, so as to incline the fibres first towards the rings f' on the discs a a', and
afterwards towards the rings on the discs a' a and inversely when the fibres enter
into the grooves g of the rings for f¹ which gather them up and carry them
onward.
By the rapid rotation of the drum, burrs, thorns and other impedimenta adhering
lightly to the surface of the wool or other fibrous substance are thrown off
therefrom, while those which are more closely entangled therein, being unable to
lodge in the interstices between the rings f.J' or in the grooves g remain on the
drum simply adhering to the external surface of the staple without forming an
integral portion thereof.
The drum C in continuing to revolve then submits the staple to the threshing
action of a toothed roller H which revolves rapidly in a contrary direction to the
travel of the drum whereby the burrs are disengaged therefrom after which the
staple is in a similar manner conveyed to and submitted to the action of a second

page_text: toothed roller K which completes the elimination of the burrs, thorns, and other
impurities from the staple. After being thus cleansed the staple is caught up by
a revolving brush D mounted between the drum catcher and the carding roller E,
to which latter it is conveyed by the action of the brush D. The surfaces of the
feed rollers are furnished with projections which are made sufficiently large to
eliminate without disintegrating the burrs, thorns and other impurities.
I would here observe that I do not confine myself to the precise details of
construction and arrangement hereinbefore described and shewn as the same admit
of modification without departing from the essential features of my invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
In combination with any suitable mechanisin for cleaning wool, cotton and other
staple a drum catcher constructed substantially in the manner hereinbefore
described and shewn acting directly upon feed rollers having a to and fro
motion all substantially as herein before specified.
