Apparatus for Removing Impurities from Cashmere and
other Wools.
人
I, CHARLES DELERUE, of 5 Rue de la Fosse aux Chènes, Roubaix (Nord)
France, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to apparatus whereby impurities, such as short or dead
hairs, vegetable or other matters, from cashmere and other wools. For this
purpose, the wool sliver is fed by feed rollers in between a pair of cylindrical
brushes and from them it is removed by a rapidly revolving comb in contact with
which there is a more rapidly revolving cylindrical brush within a tapered casing,
having an opening through which part of the periphery of the comb projects to
meet the brush. By the current of air caused by the rapid revolution of the brush,
the wool, stripped by it off the comb, is projected towards the small end of the
casing where it is caught by a pair of hollow wire gauze cylinders and by them
delivered to a pair of feed rollers to be again subjected to the action of a cylindrical
comb and brush. These wire gauze cylinders, feed rollers and combs and the
brushes and their casings are repeated eight or ten times in the machine the wool
passing in succession through them all.
During the progress of the wool through the machine the impurities are separated
from it by the successive combs and delivered on bent plates forming shoots leading
them outside.
In order to ensure
All the cylinders, feed rollers, cylindrical combs and brushes are fixed on vertical
spindles which are driven from one prime moving shaft by bands passing round
pulleys on the spindles beneath the floor of the machine.
steadiness, notwithstanding the rapid rotation of the combs and brushes, each of
these is made hollow and within it there is a standard projecting up from a plate
forming the floor of the machine. This standard has at its top the upper bearing
of the vertical spindle, the lower bearing of which is on the base of the machine
below the driving pulley. The upper end of the spindle on which the upper end
of the cylindrical comb or brush is secured by a nut presents an oil cup from
which lubricant flows by a groove in the spindle to the bearing at the top of the
standard.

Apparatus for Removing Impurities from Cashmere and
other Wools.
I, CHARLES DELERUE, of 5 Rue de la Fosse aux Chènes, Roubaix (Nord)
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 relates to apparatus whereby animal and vegetable impurities
such as short or dead hairs are removed by centrifugal action from cashmere and
other woole

page_text: I will describe the said apparatus with reference to the accompanying drawings,
in which Fig. 1 shews a side elevation, Fig. 2 a plan and Fig. 3 a vertical section
of the cylindrical comb C.
The cashmere wool, in the form of bands, is fed into the machine between a pair
of feed rollers A which deliver it between a pair of cylinders B with brush surface;
these cylinders seize the fibres and deliver them into the cylindrical comb C, which
has its surface fluted, and on the ridges a are fixed short comb teeth b arranged
approximately tangential to the circular periphery. The comb cylinder as shewn
in the section at Fig. 3, has its upper end fixed to a disc c attached to the end of a
spindle d. Into the hollow lower end of the brush cylinder projects a coned
support D fixed to the cross bar E and having at its upper end a bearing e for the
spindle d which extends downwards to a step bearing f. By providing a bearing e
at the upper end of the spindle close to the rigid support D any material vibrations
of the spindle owing to its great speed of rotation, are prevented; this speed, which
is equal to 1,400 revolutions per minute, produces a centrifugal action whereby all
the impurities are removed from the wool, during its passage from the brushes B B,
to the brush F.
The upper threaded end of the spindle d extends beyond the disc c of the comb
and upon it is screwed a jam nut 9, part of which projects beyond the spindle thus
forming an oil cup h from which a small passage extends through the spindle to the
bearing e for lubrication.
The brush F is a cylinder having a brush surface of from 2 to 3 c.m. in height;
it is mounted on a spindle in the same way as the comb C, and revolves at a speed
of about 3,750 revolutions per minute within a fixed metal casing G having an
opening at the point where the brush is in contact with the comb C.
On the casing G is fixed a sheet metal guard X formed and bent as shewn in
front view, side view and plan at Figs. 4, 44, and 4"; it has for its object to
prevent the short or dead hairs and other impurities thrown out by the first comb C
from passing on to the second comb C', and 'to cause them to collect on its inclined
surface. The mass of impurities, as it accumulates slides down the inclined surface
on to a receptacle below.
The brush F, owing to its high speed, takes from the comb C the remainder of
the wool carried round by it and in producing an air current like a fan it throws the
same to the other end of the casing G which is closed by a pair of hollow feed
rollers H H the surfaces of which are of wire gauze with meshes of from 2 to 3 mm.
square, which retain the fibre on their surface while allowing the air current to
escape through them. These rollers are fixed to revolving spindles and deliver the
wool to small cylindrical brushes II with brush or velvet surfaces which also
revolve on spindles and are in contact with the cylinders H so as to take up there-
from the adhering fibres, and present the same to the second cylindrical comb C'
and brush F', and so on, through any number of similar apparatus.
The casing G of the last brush opens into a large chamber in which the
cashmere wool is received, entirely freed from short or dead hairs and other
impurities.
The speed of the parts A C C¹ C' &c. is made proportional to the size of the
band of wool presented to them and also to the greater or less proportion of
impurities that may be contained therein, that have to be removed.
The entire apparatus is driven by a single driving shaft provided with pullies and
belts or cords corresponding to the different spindles of the combs, brushes and feed
rollers, as shewn.
There may be one such apparatus arranged on each side of the driving shaft
which can then serve to work both.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The construction and use of apparatus for removing short or dead hairs and other

described with reference to the accompanying drawings.
