OLIVER IMRAY of No 28 Southampton Buildings Chancery Lane in the County
of Middlesex "AN IMPROVED METHOD AND APPARATUS FOR CLEARING WOOL
AND OTHER TEXTILE FIBRE FROM FRAGMENTS OF STRAW AND OTHER FRIABLE
MATTER [Communicated to him from abroad by La Société Harmel Fréres of
Val des Bois (Marne) France]
According to this invention the wool or other textile fibre, as it passes from the
first combing cylinder of a carding machine, is caused to pass over a roller on which
it is pressed by other loaded rollers, either the lower roller or the upper rollers
being fluted, and thus the fragments of straw or friable, matter are crushed and
pulverised so that during the farther combing they are got rid of.

OLIVER IMRAY of No: 28 Southampton Buildings, Chancery Lane in the County
of Middlesex AN IMPROVED METHOD AND APPARATUS FOR CLEARING WOOL AND
OTHER TEXTILE FIBRE FROM FRAGMENTS OF STRAW AND OTHER FRIABLE MATTER
A communication to me from abroad by La Societé Harmel Frères of Val des Bois
(Marne) France
According to this invention, the wool or other textile fibre, as it. passes from the
first combing cylinder of a carding machine, is caused to pass over a roller on which
it is pressed by other loaded rollers, either the lower roller or the upper rollers
being fluted, and thus the fragments of straw or friable matter are crushed and
pulverized so that, during the farther combing, they are got rid of.
Fig. 1 is a section and fig. 2 a plan shewing apparatus according to this invention,
applied to a double drum carding machine. A A are two rollers pressing, either by
their own weight or, when required, with additional load, on a lower roller B so as
to squeeze the sliver passing in a thin film from the first carding drum C, from
which it is removed by the reciprocating knife F. As the sliver is extremely thin,
the fragments of foreign material which may be mixed with it project from its
general surface, and these, receiving the pressure between the rollers A and B,
become crushed and pulverized so that, when the sliver passes by the roller D to
the second crushing drum H and over that drum, the dust to which the impurities
are reduced is shaken out. The rollers A A or the roller B may be smooth or fluted,
and instead of two rollers A A one may be used. Where there are several sets of
carding drums in one machine, squeezing rollers such as A and B may be placed
between any pair of these or between all the pairs, the object in all cases being to
apply the squeezing action to the material when it is in the condition of very thin
sliver, so as to crush to powder the thicker fragments of matters mixed with it, and
to have this powder shaken out by the subsequent carding.
Having thus described the nature of the said invention, and in what manner
the same is to be performed, as communicated to me by my foreign correspondents,
I claim,
First: The herein described method of clearing wool and other textile fibre
from fragments of straw and other friable matter by subjecting thin sliver of the
fibre to the pressure of rollers on its way from one carding drum to another.
Second The use of squeezing rollers in combination with and intermediate
to a pair of carding drums, substantially as and for the purposes herein set forth.
In Witness whereof, I the said Oliver Imray have hereunto set my hand and
seal this twenty-ninth day of January, in the year of our Lord, one thousand
eight hundred and eighty-three.
