I, ERNEST DE Pass, of Fleet Chambers, 68, Fleet Street, in the City
of London, .Patent Agent, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN APPARATUS CONNECTED WITH THE TWISTING
AND UNTWISTING OF THREADS FOR CLEANING THEM BY FRICTION," communicated
to me from abroad by Joseph Imbs, of 17, Boulevart Saint Martin, Paris,
France, to be as follows:-
.
This Invention relates to apparatus for cleaning and laying the twists
of threads of textile materials by friction of the threads against each
:

page_text: other, and also to obtain by this arrangement a more energetic and less
fatiguing action for the thread.
In a revolving frame or case I arrange any desired number of rollers,
around which the thread is rolled in such manner that the twist put
into.it by the rotation of the frame or case is laid or set by friction
while on the rollers, the threads becoming untwisted as they pass off the
last or end roller, and out of the case at the opposite end of it. Each
end of the frame or case has a hollow bearing working in suitable
supports. Motion is imparted to this frame or case by means of a cord,
chain, or band passing over a grooved pulley or wheel mounted on one
of the bearings, such cord, chain, or band being brought from a drum
or otherwise. The threads pass into the frame through one of the
hollow bearings, which serve as guides, and they become twisted in the
direction of rotation of the frame as soon as it reaches the first roller
where it commences to receive its rolling up and frictioning. The threads
thus twisted into a single thread remain so till they reach the last roller,
when they become untwisted in leaving the case in the exact quantity
in which they were twisted on entering, and they thence, pass to the
bobbins.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Ernest de Pass in the Great Seal Patent Office
on the 9th May 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ERNEST
DE PASS, of Fleet Chambers, 68, Fleet Street, in the City of London,
Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her.
Letters Patent, bearing date the Thirteenth day of November, in the 3
year of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Ernest de Pass, Her special

page_text: license that I, the said Ernest de Pass, my executors, administrators,
and assigns, or such others as I, the said Ernest de Pass, my exccutors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN APPARATUS CONNECTED WITH THE TWISTING AND UNTWISTING OF THREADS FOR
CLEANING THEM BY FRICTION," communicated to me from abroad by Joseph
Imbs, of 17, Boulevart Saint Martin, Paris, France, upon the condition
(amongst others) that I, the said Ernest de Pass, my executors or
administrators, by an instrument in writing under my, or their, or
one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal
Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said Ernest de Pass, 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 thereof, reference being had to the accompanying
Drawings and to the letters and figures marked thereon, as commu-
nicated to me, that is to say :—
This Invention relates to apparatus for cleaning and laying the twists
of threads of textile materials by friction of the threads against each
other, and also obtaining by this arrangement a more energetic and less
fatiguing action for the thread.
In a revolving frame or case I arrange any desired number of rollers,
around which the thread is rolled in such manner that the twist put
into it by the rotation of the frame or case is laid or set by friction
while on the rollers, the threads becoming untwisted as they pass off the
last or end roller, and out of the case at the opposite end of it. Each
end of the frame or case has a hollow bearing working in suitable
supports. Motion is imparted to this frame or case by means of a cord,
chain, or band passing over a grooved pulley or whorl mounted on one
of the bearings, such cord, chain, or band being brought from a drumor
otherwise. The threads pass into the frame through one of the hollow

page_text: when they become untwisted in leaving the case in the exact proportion
in which they were twisted on entering, and they thence pass to the
bobbins.
The rollers are turned or caused to rotate by the drawing of wrap of
the thread on to the bobbins, and they are always kept in a direction of
rotation transverse to the threads, so as to twist and untwist them.
I now proceed with reference to the accompanying Drawings to
describe an apparatus constructed according to the Invention, of
which Fig. 1 is a sectional elevation, and Fig. 2 a transverse vertical
section.
.
A is the case or frame carrying the rollers m, m, on which the thread
to recieve friction is rolled; the ends of the case or frame form heads or
bearings B, B', which work in supports S, S', with great speed. Motion
is imparted to this frame by any ordinary means, as for example, by a
cord, chain, or band f passing over a grooved pulley or whorl c mounted
on the bearing B', and brought from a drum or otherwise. The two
heads or bearings are hollow and form passages a, a¹.
The threads (shown in red lines) enter the case in the direction of the
arrow z, and pass in through the passage a and become twisted in the
direction of rotation of the case or frame on reaching the point g or first
roller m, which is first point of rolling up and and frictioning. The g
threads thus twisted remain so until they reach the point g¹ (or last
roller m) which is the last point of rolling up and frictioning, but directly
they leave the last roller they become untwisted in exactly the same
proportion as they were twisted on entering the case or frame, and
passing out through the other head or bearing B' in the direction of the
arrow z are conducted on to the bobbins.
The rollers m, m, are turned or caused to rotate by the drawing or
wrap of the threads on th the bobbins, and they are always kept in a
direction of rotation transverse to the threads, so as to twist and untwist
them. The rollers are held in the frame by means of sockets or screw 8
caps x. By this arrangement of apparatus two advantages are thus

page_text: obtained, first, in passing in a single thread and imparting friction to it
under a torsion or twisting momentarily superior to that which it
already possesses; second, in passing in at the same time several threads
and frictioning them together whilst they are momentarily twisted
together, and recieving them untwisted in exactly the same proportion
as they were twisted.
.
This arrangement of apparatus I call "double revolving and fric-
tioning organ."
Having now described the nature of the said Invention, and in what
manner the same may be performed, I declare that I claim,—
.
First. The apparatus herein-before described and shewn in the
Drawings for cleaning the threads of textile materials by friction of the
threads against each other, thus obtaining a more energetic and less
fatiguing action for the threads.
Second. Arranging rollers in or to an apparatus and over which
threads pass in a direction of rotation transverse to the threads, so as to
twist and untwist them, as set forth, such rollers being rotated by the
wrap of the threads on their way to the bobbins, as herein-before
described.
In witness whereof, I, the said Ernest de Pass, have hereunto set
my hand and seal, this Second day of May, in the year of our
Lord One thousand eight hundred and seventy-six.
