I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lano, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the. nature of the said Invention for "IMPROVEMENTS
IN THREAD SEPARATORS AND CLEANERS FOR RING SPINNING FRAMES " to be as
follows:-
°
This Invention relates to separators for ring spinning frames and consists in such
a construction of separator as that its small columns or supports are arranged back
of the centre of the ring rail, thus leaving the front or working side open or clear,
and in such proximity to each pair of rings as that each of said supports serves as
a traveller cleaner for two rings, as hereinafter more fully explained. It also
consists in a continuous construction of separator throughout the whole length of
the ring rail, and in a special and advantageous form and disposition relatively to
the rings of the several separating or guiding surfaces of the separator.
The separator is made continuous the whole length of the spinning frame or
ring rail, and is made up of a series of separators to take in the several rings.
Each of these individual separators commence at a point a about one fourth (more
or less) of the diameter of the ring, back of its front, on the right hand side of the
ring (as viewed from the front of the frame) and at about one eighth of an inch
(more or less) outside of a vertical line extended upward from the outer margin of
the upper portion of the ring. From said point each separator is curved in
concentric relation with the ring, backward and around the ring as it were to a
point 6 thereby including about one half the circumference of the ring, and from
this point b it is extended in a diverging direction until it intersects the starting
point a of the next adjacent separator and so on indefinitely throughout the whole
length of the rail.
The compound separator as these individual separators combined in the one
structure may be termed, may stand at about two and one half inches more or less,
above the ring rail, and may be of a strip like construction of one inch more or less
in depth.

page_text: Such compound separator which takes in two or more individual separators, is
carried by small upright supports or columns arranged centrally between every
other ring at or in proximity to the backs thereof. These supports have
enlargements or projections at such a height as to be on a level with the paths of
the travellers and in such proximity to the rings that the travellers in making
their circuits around the rings, barely or only just cleave the projections. These
projections which are virtually portions of the supports or columns constitute
traveller cleaners or clearers, by knocking off all cotton or fibres of cotton or lint
adhering to the travellers by the increased resistance of the atmosphere.
By the arrangement of the traveller cleaners as described, each cleaner which is
but a part or enlargement of the support it is attached to, serves to clean the
travellers on two rings. The construction of such traveller cleaners by making
them enlargements of or projections from the supports is in part that said supports
may be carried as far back of the centres of the rings as practicable thus leaving
the front or working part of the ring rail open so that the travellers on the rings
are easily reached by the fingers of the operator no matter on what part of the rings
they may stop.

I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THREAD SEPARATORS AND CLEANERS FOR RING SPINNING FRAMES" and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement:-
In ring spinning more or less difficulty has been experienced by manufacturers
from the fact as often is the case that when one thread breaks or rather when the
thread refuses to pass through the traveller by reason of a bunch or by reason of
a fine splinter getting crosswise thereof the same slacks up and will generally
sweep down several contiguous threads.
Again especially when spinning at very high speeds, no little difficulty has been
found in so adapting the tension of the thread, which is done by the weight of the
traveller as to prevent unnecessary breakages and here it may be stated that from
the time the frame starts after doffing, until the bobbin is full the tension is
constantly varying or decreasing by reason of the diminishing acuteness of the angle
which the thread assumes, so that if a traveller be used which is light enough to
give the required tension to the thread when the bobbin first begins to fill, the
tension will be so light, when it gets partially, or say two thirds full, that the
weight of the traveller is not sufficient to keep the thread from throwing or bulging
out, and thus two or more threads come in collision thereby causing the breakage
of one or more thereof.

page_text: To prevent these bulging threads from coming in contact with each other,
separators have been used consisting of pieces of wire or thin castings or plates of
steel, tin or other hard substance introduced between the spindles and serving as
guides for the threads. Thus separate pieces of wire have been bent partially
around each adjacent pair of rings on which the travellers run and the ends of said
wires bent down and passed through the rail sufficiently near the rings to provide
for the travellers clearing them and forming supports on the front side of the centre
of the rail or working side of the frame.
This invention consists in such a construction of separator as that its small
columns or supports are arranged back of the centre of the ring rail, thus leaving
the front or working side open or clear, and in such proximity to each pair of rings
as that each of said supports serves as a traveller cleaner for two rings, as herein-
after more fully explained. It also consists in a continuous construction of
separator throughout the whole length of the ring rail, and in a special and
advantageous form and disposition relatively to the rings of the several separating
or guiding surfaces of the separator.
Reference is to be had to the accompanying drawings forming part of this
specification in which similar letters of reference indicate corresponding parts in
both the figures.
Figure 1 represents a view in perspective as seen from the front mainly of a
ring rail in part, with the improved separator applied to certain of the rings and
with one of the bobbin spindles and bobbins in place and
Figure 2 is a plan view of the same omitting the spindle and bobbin.
A indicates the ring rail of a spinning frame and B, B, the rings arranged therein
and thereon and of which there may be any number in a row or series; C, C, aro
the travellers which run upon said rings and D, is one of the spindles, and E its
bobbin.
The separator is made continuous, the whole length of the spinning frame or
ring rail, and is made up of a serios of separators G₁ to take in the several rings.
Each of these individual separators commences at a point b about one fourth (more
or less) of the diameter of the ring, back of its front on the right hand side of the
ring, as viewed from the front of the frame and at about one eighth of an inch
(more or less) outside of a vertical line extended upward from the outer margin c
of the upper portion of the ring. From said point 6 each separator C is curved in
concentric relation with the ring, backward and around the ring as it were to a
point d, thereby including about one half of tho circumference of the ring and
from this point d it is extended in a diverging direction until it intersects the
starting point b, of the next adjacent separator G' and so on indefinitely throughout
the whole length of the rail.
The compound separator as these individual separators G' combined in the one
structure, may be turmed, may stand at about two and one half inches more or less
above the ring rail, and may be of a strip like construction of one inch more or less
in depth.
Such compound separator which takes in two or more individual separators, is
carried by small upright supports or columns H arranged centrally between every
other ring B, B, at or in proximity to the backs thereof. The supports H have
enlargements or projections I, at such a height as to be on a level with the paths of
the travellers C, C, and in such proximity to the rings that the travellers in making
their circuits around the rings, barely or only just clear the projections I These
projections which are virtually portions of the supports or columns H constitute
traveller cleaners or clearers, by knocking off all cotton or fibres of cotton or lint
adhering to the travellers. The importance of this will be best understood by
stating that ordinarily, the travellers through which the thread passes, becomes
choked by reason of fibres of cotton and lint becoming detached from the thread in
passing through the same and the accumulation of such cotton or lint about the
traveller in the form of a wal or bunch and which by reason of the great velocity
with which the traveller is propelled not only increases the weight of the traveller

page_text: but presenting a somewhat bulky substance, it meets with great resistance from
the atmosphere so that the tension of the thread is increased, in part by the
increased weight of the traveller and in part by the increased resistance of the
atmosphere.
By the arrangement of the traveller cleaners I as described each cleaner, which
is but a part or enlargement of the support H it is attached to, serves to clean the
travellers C on two rings B, B. The construction of such traveller cleaners I by
making them enlargements of or projections from the supports H is in part that
said supports H may be carried as far back of the centres of the rings as practicable,
thus leaving the front or working part of the ring rail open so that the travellers on
the rings are easily reached by the fingers of the operator no mattor on what part
of the rings they may stop.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
1st The combination with the ring rail A, the rings B and supports H, of a series
of united separators G provided with points b each separator being curved from
the said points concentric with and about one half of the circumference of the rings
and thence diverging to the point of the adjacent separator and secured thereto
substantially as herein shown and described.
2nd The combination with the ring rail, the rings and travellers of the united
curved separators G' the supports H arranged between alternate pairs of rings in
proximity to the backs thereof and the clearers I formed or arranged upon said
supports on a level with the paths of the travellers substantially as herein shown
and described whereby the supports serve to support both the separators and
clearers as set forth.
