IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR DESTROYING
SOLID IMPURITIES SUCH AS TEAZELS, WOOD PARTICLES, BURS AND THE LIKE FROM
TEXTILE MATERIALS [A communication to him from abroad by La Société
Harmel Fréres of Val des Bois (Marne) France.
"
The means employed hitherto for destroying and removing hard impurities such
as teazels, woody particles, burs and the like from textile materials consist in the
use of various chemical processes and of arrangements for crushing such matters
between revolving cylinders.
The present invention consists in subjecting the textile material to repeated
percussive action whereby such impurities are completely destroyed without injury
to the textile material.
The apparatus employed for this purpose may be variously arranged, thus
according to one arrangement the textile material is caused to pass from the first
doffing cylinder of a carding machine over a drum or cylinder upon the surface of
which two levers having serrations or prongs at their extremities are caused to act
with repeated blows by means of revolving cams or other devices, so as to crush
the impurities as the textile material passes over the cylinder, after, which the
material passes to the second train of the carding machine.
Similar apparatus may be employed at various points in the trains of one and
the same carding machine, such as between the first train and the main carding
cylinder, and between the successive carding cylinders, as also, after the material
leaves the last doffing cylinder.
The process may also be applied to the textile material when passing through
the drawing frames, gill combs, and other combing and spinning machinery.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Oliver Imray in the Great Seal Patent Office on the 18th April
1883.
OLIVER IMRAY of No 28 Southampton Buildings, Chancery Lane, in the County
of Middlesex "IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR DESTROYING
SOLID IMPURITIES, SUCH AS TEAZLES, WOOD PARTICLES, BURS AND THE LIKE FROM
TEXTILE MATERIALS" A communication to me from abroad by La Societé Harmel
Frères of Val des Bois (Marne) France.
The means employed hitherto for destroying and removing hard impurities such
'as teazles, woody particles, burs and the like from textile materials consist in the
use of various chemical mechanical processes, and of arrangements for crushing such
matters between revolving cylinders.
The present invention consists in subjecting the textile material to repeated
percussive action, whereby such impurities are completely destroyed without injury
to the textile material.
The apparatus employed for this purpose may be variously arranged; thus,
according to one arrangement, which is shewn on the accompanying drawing, the
textile material is caused to pass from the first doffing cylinder F of a carding
machine over a drum or cylinder D, upon the surface of which two levers A and B
pivotted at O O, having serrations or prongs at their extremities, are caused to act
with repeated blows by means of revolving cams or other devices, such as a
revolving disc C with pins a a, so as to crush the impurities as the textile material
passes over the cylinder F, after which the material is led by the cylinder H to the
card cylinder J of the second train of the carding machine. Springs R R are
provided for imparting elasticity to the action of the levers.
Similar apparatus may be employed at various points in the trains of one and the
same carding machine, such as between tlie first train and the main carding
cylinder, and between the successive carding cylinders.
The process may also be applied to the textile material when passing through
the drawing frames, gill combs, and other combing and spinning machinery
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 Destroying and removing hard impurities contained in woollen and other
textile materials, by subjecting the same to a repeated rapid pércussive action, while
being passed in a thin sheet or fleece over a hard surface.
Second: The use for destroying hard inipurities contained in woollen and other
textile materials, of rapidly vibrating beaters, caused to exert blows upon the textile
material as it passes over a hard surface, substantially as herein described with
reference to the accompanying drawing.
In Witness whereof I the said Oliver Imray have hereunto set my hand
and seal this eighteenth day of April in the year of our Lord, one thousand,
eight hundred and eighty-three.
