Improvements in Carding Machines.
We, ARMAND RIVRET, of Roubaix and HIPOLYTE HONORÉ-COLSON of Tourcoing
both in the Republic of France, Engineers do hereby declare the naturo of the
said invention to be as follows:-
In the carding of wool as now practised the wool is delivered to the feeding rollers
by an apron moving at a regular speed; the feeding rollers take the wool and deliver
it to a toothed roller called in French roule-ta-bosse which draws it round and
presents it to the action of one or more beaters which drive away all the hard foreign
bodies contained in the wool such as stones, seeds, thistles and so forth. This toothed
roller and its benters constitute an arrangement which inay be used singly in the case
of more or less clean wool; but which may be doubled or tripled in the case of wool
containing a large quantity of seed and thistles. But even when using a number of
these apparatuses in any given carding machine it has not heretofore been possible to
remove the whole of the foreign bodies from the wool; the stones and seeds are
wholly removed, but many of the thistles escape the action of the beaters because the
wool taken from the feed rollers is often placed on the toothed roller in tufts which
enclose thistles and protect them from the action of the beaters so that these thistles
go forward with the wool to the cards. If however the arrangements forming the
subject of the present invention, and shown in the annexed drawings, are adopted the
tufts of wool are opened before they reach the beaters by means of a comb having a
to and fro movement tangential to the toothed roller and the blunt teeth of which
comb work with the teeth of the said toothed roller so as to open the tufts of wool and
liberate the thistles which are not pricked by the blunt teeth of the comb but are
either retained thereby and remain placed on the upper side of the comb or are
separated from the wool brought forward by the toothed roller and remain attached to
the wool hooked on to the said roller in such a condition that being no longer protected
by the wool the beaters act effectually to remove them.
The thistles and tufts of wool which rest against the comb are removed by a brush
which delivers them back to the feed rollers and thence they pass again to the toothed
roller.
The drawings illustrate two arrangements of apparatus constructed in accordance
with our invention.
In the arrangement shown in Figure 1 the wool placed on the apron A is taken by
the feeding rollers B C which deliver it to the toothed roller F; after passing about a
quarter of a turn round this roller the wool arrives under the comb G which has a to
and fro movement imparted to it by the crank k and the links R, P, Q Jointed
at M NLO and acts on the tufts of wool hooked on to the toothed roller dividing them
and keeping the thistles and tufts of wool which are too large to pass between the
blunt teeth, on its upper part. The action of the comb assures the booking of the
wool on to the toothed roller and raises the thistle, which then partly disengaged, is
prepared for the action of the beater or beaters H.
The fibres and thistles remaining on the upper side of the comb G are removed
therefrom by the rotating brush E when the comb in its to and fro movement comes
under the action thereof. This brush delivers the fibres and thistles to the roller D
which returns them to the toothed roller F.
The wool after having been subjected to the action of the beater or beaters placed
at H is taken off by the stripping roller I which delivers it to the carding drum J.
it will be understood that in some cases the reciprocating comb G may be replaced
by a series of combs mounted on a rotating drum S as shown in Figure 2. In this

page_text: case the blunt teeth of the combs are freed of their wool and thistles by the brush E¹
which delivers them to the roller D and to the toothed roller F.
In every case the thistles removed by the beater or beaters H (Figures 1 and 2) are
projected into a sheet iron trough J where they are stored till reinoved.

Improvements in Carding Machines.
We, ARMAND RIVRET, of Roubaix, and HIPOLYTE HONORE 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 accompanying sheet of drawings and to the letters and figures marked thereon,
that is to say :-
In the carding of wool, as now practised, the wool is delivered to the feeding
rollers by an apron moving at a regular speed; the feeding rollers take the wool and
deliver it to a toothed roller or licker-in called in French "roule-ta-bosse" which
draws it round and prosents it to the action of one or more beaters which drive away
the hard foreign bodies contained in the wool, such as stones, seeds, thistles and so
forth. This licker-in, and its beaters, constitute an arrangement which may be used
singly in the case of more or less clean wool: but which may be doubled or tripled in
the case of wool containing a large quantity of seeds and thistles. But even when
using a number of these apparatuses in any given carding machine it has not bereto-
fore been possible to remove the whole of the foreign bodies from the wool; the stones
and seeds are wholly removed, but many of the thistles escape the action of the beaters
because the wool, taken from the feed rollers, is often placed on the licker-in in tufts
which enclose thistles and protect them from the action of the beaters, so that these
thistles go forward with the wool to the cards. If however the arrangements forming
the subject of the present invention, and shown in the aunexed drawings, are adopted,
the tufts of wool are opened out, before they reach the beaters, by means of a comb
having a movement tangential to the licker-in, and the blunt teeth of which comb are
opposed to the teeth of the said licker-in, so as to open the tufts of wool and liberate
the thistles, which are not pricked by the blunt teeth of the comb, but are either
retained thereby and remain placed on the upper side of the comb or remain attached
to the wool hooked on to the licker-in in such a condition that, being no longer
protected by the wool, the heaters subsequently act effectually to remove them.
The thistles and tufts of wool which remain on the comb are removed by a brush
which delivers tho wool back to the feed rollers which in turn pass it again to the.
licker-in.
The drawings illustrate two arrangements of apparatus constructed in accordance
with our invention.
In the arrangement shown in Figure 1, the wool placed on the apron A is taken by
the feeding rollers B C which deliver it to the licker-in roller F; after passing a
quarter of a turn round the licker-in roller, the wool arrives under the comb G which
has a to and fro movement imparted to it by the crank k, and the links R P Q jointed
at M N LO, and acts at the point X on the tufts of wool hooked on to the licker-in,
dividing them and keeping the thistles and tufts of wool, which are too large to pass
between the blunt teeth, on its upper part. The action of the comb assures. the
hooking of the wool on to the licker-in and raises up the thistles which, 'thus partly
disengaged, are, prepared for the action of the heater or beaters 'H, preferably placed
between the brush a (which completes the isolation of the thistles from the wool by
pressing the latter into the teeth of the licker-in F, leaving the thistles standing on
•

page_text: the surface of the latter) and the rigid blade d, the brush a and blade d cooperating to
retain the wool on the licker-in, while the beater or beaters H completely remove the
thistles thus exposed to their action.
The fibres and thistles remaining on the upper side of the comb G are removed
therefrom by the rotating brush E when the comb in its to and fro movement comes
under the action thereof. This brush clears the comb G of the wool already opened,
and from the thistles which are for the most part detached, and delivers the fibres to
the roller D which returns them to the licker-in F, the thistles being expelled.
The wool, after having been subjected to the action of the beater or beaters
placed at H, is taken off by the stripping roller I which delivers it to the carding
drum J.
In some forms of carding machines the reciprocating comb G may be replaced
with advantage by a series of blunt combs mounted on a rotating drum S, as shown
in Figure 2. In this case the blunt teeth of the combs are freed of their wool and
thistles by the brush E' which delivers the wool to the brush E, whence it is returned
by the roller D to the licker-in as described in reference to the reciprocating comb
arrangement shown in Figure 1.
In every case the thistles removed by the beater or beaters H (Figures 1 and 2) are
projected into a sheet iron trough T where they are stored till removed.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
First-In a carding machine, the employment, in connection with the licker-in
roller F, of a comb G having blunt teeth opposed to those of the said licker-in
roller, the said comb having a to and fro or reciprocating motion imparted thereto,
whereby tufts of wool, enclosing thistles or other hard foreign bodies, are divided
or opened out; the wool retained by the said comb is delivered to a rotary
brush E, from which it is returned by the roller D to the licker-in roller, and the
thistles or other hard foreign bodies, disengaged more or less from the tufts of wool,
are prepared by the said comb for subsequent expulsion by the beator or beaters H,
as herein before described, and illustrated in Figure 1 of the drawings.
Second In a carding machine, the employment, in connection with the licker-in
roller F, of a comb S having blunt teeth opposed to those of the said licker-in roller, the
said comb S having a continuous rotary motion imparted thereto, whereby tufts of wool,
enclosing thistles or other hard foreign bodies, are divided or opened out; the wool
retained by the said comb is delivered to a rotary brush E', from which it is returned
by the brush E and roller D to the licker-in roller, and the thistles or other hard
foreign bodies, disengaged more or less from the tufts of wool, are prepared by the
said comb for subsequent expulsion by the beater or beaters H, as hereinbefore
described, and illustrated in Figure 2 of the drawings.
Third In a carding machine, the combination of the licker-in roller F, the
reciprocating comb G, the brush E, the roller D, and the thistle clearer consisting of
a beater H, a brush a, and a rigid blade d, all arranged and operating as hereinbefore
described, and illustrated in Figure 1 of the drawings, and for the purpose specified.
Fourth In a carding machine, the combination of the licker-in roller F, the
rotating comb S, the brush E', the brush E, the roller D, and the thistle clearer
consisting of a beater H, a brush a, and a rigid blade d, all arranged and operating
as hereinbefore described, and illustrated in Figure 2 of the drawings, and for the
purpose specified.
