Improvements in Carding Machines.
We, ARMAND RIVRET, of Roubaix, and HIPPOLYTE HONORÉ-COLSON, of
Tourcoing, both in the Republic of France, Engineers, do hereby declare the
nature of the said invention to be as follows
--
The object of the improvements forming the subject of this invention is to clear
wool, before carding, from all hard bodies, stones, thistles and so forth, which it
may contain, and the improvements consist essentially in the employment, in
connection with a beater and a rigid blade, of a straight brush of special con-
struction, the said brush and blade being applied at a short distance from one
another tangentially to the licker-in roller. The aforesaid special brush is composed
of one or more rows of pigs' bristles, or of any other suitable animal or vegetable
substance, and of oue, two, or more, rows of tempered steel wires. The pigs'
bristles, which are supported by the metallic wire bristles, force the wool into the
teeth of the licker-in, thereby stripping the said wool from the thistles, or other
hard bodies, which cannot enter between these teeth; the steel wire bristles
complete the forcing of this wool to the bottom of these teeth and thereby the
perfect isolation or separation of the thistles or other hard bodies from the wool is
effected. It will be understood that the beater is placed between the aforesaid
special brush and the rigid blade, which latter holds the wool in the teeth of the
licker-in while the beater acts to expel the thistles or other hard bodies which, by
the action of the said brush, are no longer surrounded by the wool so as to offer
resistance to the action of the beater.
This arrangement of the beater, the special brush and the rigid blade, differs
from the ordinary arrangements and from those for which we have already applied
for or have obtained Patents, as none of the known arrangements heretofore
suggested or employed to clear thistles or other hard bodies from wool have
possessed, so far as we are aware, this simplified application of the beater placed

ordinary arrangements, the beater is preceded by a rigid blade or, as in the improved
apparatus for which we applied for a Patent on the 1st August 1889 No. 12246, is
followed by one, or is in some other cases placed between two rigid blades. In the
apparatus, forming the subject of our aforesaid application for a Patent, the beater
is placed between an ordinary straight brush and a rigid blade, and acts concurrently
with a reciprocating or rotating comb. In this case, the ordinary brush rapidly
wears out and retains little or none of the wool on the licker-in, so that it does not
effect the isolation or separation of the thistles. When two blades are employed,
one placed in front of the beater and the other behind it, the result is better if the
apparatus meets only with hard bodies of sensibly uniform size, but immediately a
larger body presents itself the blade springs and only acts upon it, leaving the
smaller ones imaffected.
By the use of our new combination of specially constructed brush, with a beater
and rigid blade, a much more perfect effect is obtained, because the said brush acts
to clear the wool from the thistles whatever may be their sizes and positions in the
tufts of wool containing them, so that the beater has only to act upon hard bodies
which are sofar isolated and uncovered that they do not adhere materially to the
wool which is perfectly enclosed in and held by the teeth of the licker-in; the
beater does not act therefore in any way on the wool but only on the thistles or
other hard bodies which it infallibly expels.
Figure 1 of the drawings hereto annexed shows diagrammatically a thistle-
clearing apparatus constructed and applied, in accordance with our invention, to the

to require the action of two or more similar apparatuses, they may be arranged in
the space between the feed rollers and the detaching roller.

COMPLETE SPECIFICATION.
Improvements in Carding Machines.
We, ARMAND RIVET, of Roubaix, and HirrotYTE HONORR-COLSON, of
Tourcoing, both in the Republic of France. Engineers, do hereby declare the
nature of the said invention, and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement, reference
being had to the sheet of drawings annexed to our Provisional Specification, and
to the letters and figures marked thereon, that is to say :-
The object of the improvements forming the subject of this invention is to clear
wool, before enrding, from all hard bodies, stones, thistles and so forth which it may
contain, and the improvements consist essentially in the employment in connection
with a heater and a rigid blade of a straight brush of special construction, the said
brush and blade being applied at a short distance from one another tangentially to

page_text: the licker-in roller. The aforesaid special brush is composed of one or more rows
of pigs bristles, or of any other suitable animal or vegetable material and of one,
two or more rows of tempered steel wires. The pigs bristles which are supported
by the metallic wire bristles, force the wool into the teeth of the licker-in, thereby
stripping the said wool from the thistles or other hard bodies which cannot enter
between these teeth; the steel wire bristles complete the forcing of this wool to the
bottom of these teeth, and thereby the perfect isolation or separation of the thistles
or other hard bodies from the wool is effected.
It will be understood that the beater is placed between the aforesaid special brush
and the rigid blade, which latter, holds the wool in the teeth of the licker-in while
the beater acts to expel the thistles or other hard bodies which, by the action of the
said brush, are no longer surrounded by the wool so as to offer resistance to the
action of the beater.
This arrangement of the beater, the special brush and the rigid blade differs from
the ordinary arrangements and from those for which we have already applied for,
or have obtained Patents, as none of the known arrangements heretofore suggested
or employed to clear thistles or other hard bodies from wool have possessed, so far
as we are aware, this simplified application of the beater placed between a brush
constructed as above described and the rigid blade. In the ordinary arrangements
the beater is preceded by a rigid blade or, as in the improved apparatus for which
we applied for a Patent on the 1st August 1889 No. 12,246 is followed by one, or
is in some other cases placed between two rigid blades. In the apparatus forming
the subject of our aforesaid application for a Patent, the beater is placed between
an ordinary straight brush and a rigid blade, and acts concurrently with a recipro-
cating or rotating comb. In this case the ordinary brush rapidly wears out and
retains little or none of the wool on the licker-in, so that it does not effect the
isolation or separation of the thistles. When two blades are employed, one placed
in front of the beater, and the other behind it, the result is better if the apparatus
meets only with hard bodies of sensibly uniform size; but immediately a larger
body presents itself, the blade springs and only acts upon it, leaving the smaller
ones unaffected.
By the use of our new combination of specially constructed brush with a beater
and rigid blade, a much more perfect effect is obtained because the said brush acts
to clear the wool from the thistles whatever may be their sizes and positions in the
tufts of wool containing them, so that the beater has only to act upon hard bodies
which are so far isolated and uncovered that they do not adhere materially to the
wool which is perfectly enclosed in and held by the teeth of the licker-in, the beater
does not act therefore in any way on the wool, but only on the thistles or other hard
bodies, which it infallibly expels.
Figure 1 of the aforesaid drawings shows diagrammatically a thistle-clearing
apparatus constructed and applied in accordance with our invention to the licker-in
of a carding machine. If the state of the wool to be worked is such as to require
the action of two or more similar apparatuses, they may be arranged in the space
between the feed rollers and the detaching roller.
Figures 2 and 3 show to a larger scale the peculiar construction of the above-
mentioned special brush.
The wool placed upon the endless apron a is conducted by the latter to the feeding
rollers be, which deliver it to the licker-iu d furnished with saw teeth. A circular

brush spreads the wool on the licker-in and cleans the feed roller c.
intermediate point between the rotating brush ƒ and the detaching roller g, we
place our thistle-clearing apparatus which consists of a beater m the special brush n
and a rigid blade p.
The special brush is made of an iron or steel bar n', Figures 2 and 3, occupying
the whole width of the carding machine with ends n² forming trunnions which take
into vertically adjustable bearings, not shown in the drawings. The bar n¹ can be
turned in the said bearings, and secured in any desired position therein by set screws
so as to adjust the bristles of the brush to the teeth of the licker-in. These bristle

page_text: comprise a longitudinal and front row aª of pigs' bristles or other suitable animal or
vegetable substance; then two or more rows of tempered steel wires. The
ends of the bundles of pigs bristles and of steel wires conpo-ing the brush are
imbricated or steppeil, as shown, so as to conform tangentially to the cylindrical
periphery of the licker-in. The rigid blade p completing the thistle-clearing
apparatus is moveable in its bearings, to allow of adjusting the position of its working
edge relatively to the teeth of the licker-in.
As already explained, the pigs' bristles a² of the brush uncovers each of the
thistles by forcing the wool therefrom into the teeth of the licker-in; the metallic
wire bristles aªàª² sustain or support the first named bristles a², assist them to hold
the thistles while the wool is being stripped off the latter, and assure the deposit of
the wool so stripped off in the teeth of the licker-in. The fixed blade pretains
the thistles and other hard bodies thus uncovered and presents them to the action
of the heater. The thistles and other hard bodies removed by the heater pare
thrown into the receiver suitably placed behind the blade p.
It may be oberved that the use of one new brush consisting of pigs' bristles for
example combined with bristle teel wire enables us to impart to the licker-in a
considerable speed of rotation so that it may be charged very lightly and still be
muule to do at least as much work in a given time as the ordinary apparatus.
Having now particularly described and ascertained the nature of the said inven-
tion, and in wint manner the same is to be performed, we declare that what we
claim is :-
First In a carding machine, the apparatus for clearing hard bodies, stones,
thistles and so forth from wool, consisting of a rigid blade, a rotary bener and a
straight fixed brush, composed of one or more rows of pigs bristles or other suitable
animal or vegetable material, and of one or more rows of tempered steel wire
bristles all constructed, arranged and applied substantially as hereinbefore described,
and illustrated in the drawings.
Serond The use in connection with the licker-in roller of a carding machine, of
one or more clearing apparatuses of the kind forming the subject of the first
claiming clause hereof, placed on the circumference of the licker-in roller between
the feeding in and the detaching roller as hereinbefore described, and illustrated
in the drawings.
Third In apparatus for clearing hard bodies, stones, thistles, and so forth from
wool, the use of a brush composed of pigs' bristles or other suitable animal or
vegetable material, and of tempered steel wire bristles as hereinbefore described
and illustrated in Figures 2 and 3 of the drawings.
