PROVISIONAL SPECIFICATION.
Improvements in and relating to Ring Spinning Machines.
I, ALFRED HITCHON, Globe Works Accrington, in the County of Lancaster
Machinist do hereby declare the nature of this invention to be as follows :-
My invention relates to the construction and mounting of separator plates, herein-
after called the separator, used to check ballooning in ring frames. The object
of my said invention is to provide a means whereby the space occupied by the
separator and its attachments is diminished, to enable the separator to be easily
thrown in and out of position, and to so construct the thread guides as to permit of
the passage of the said separator during the ascent of the ring rail.
In carrying my said invention into effect I form at the back of the ring rail in some
suitable manner a longitudinal groove in which is embedded a shaft or rod on which
is mounted the separators and so held as to be capable of a partly rotary movement.
By preference I form the rod in lengths corresponding with the length of each
section of the ring rail so that the separators for each section can be independently
operated. The separators may be loosely mounted upon the rod or may be fixed
thereto. The separator is formed with a vertical blade projecting between the
spindles and may be formed by casting stamping or other convenient manner and
may be solid, perforated or in the form of a grid. The separator has a downwardly
projecting shank from the blade terminating in a boss with an eye through which
the rod is passed and the ring rail is recessed so as to permit the said boss to lie
partly within it. A stop is provided on the boss which prevents too great a range
of oscillating movement of the separator so that it cannot fall too far forward. I
affix to the roller beam a downwardly projecting stop plate, or plates, curved on its
front face in such a way that when the separator is thrown back for doffing its back
edge comes in contact with the stop when the ring rail is raised and is thus thrown
forward into working position. In order to facilitate the upward movement of the
separators with the ring rail I form in the thread guides notches or slots between
each pair of spindles so as to permit the separators to pass upwards freely and
without obstruction.

COMPLETE SPECIFICATION.
Improvements in and relating to Ring Spinning Machines.
I, ALFRED HITCHON, Globe Works, Accrington in the County of Lancaster,
Machinist, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
My invention relates to the construction and mounting of separator plates, herein-
after called the separators, used to check ballooning in ring spinning frames.
The object of my said invention is to provide means whereby the space occupied by
the separators and their attachments is diminished, to enable the separators to be

descent of the ring rail.
In carrying my said invention into effect, I form at the back of the ring rail, in
some suitable manner, a longitudinal groove in which is embedded a shaft or rod on
which is mounted a series of separators, and which is arranged so as to be capable
of a partly rotary movement.
By preference I form the rod in lengths corresponding with the length of each.
section of the ring rail so that the separators for each section can be independently
operated. The separators may be loosely mounted upon the rod or may be fixed
thereto. Each separator is formed with a vertical blade projecting between the
spindles and may be formed by casting, stamping, or in any other convenient
manner and may be solid, perforated or in the form of a grid. The separator has a
shank projecting downwardly from the blade and terminating in a boss with an eye
through which the rod is passed and the ring rail is transversely recessed or notched
so as to permit the said boss to lie partly within it. A stop is provided on the boss
which prevents too great a range of oscillating movement of the separator so that
it cannot fall too far forward. I affix to the roller beam a downwardly projecting:
stop plate, or plates, or equivalent devices curved on its front face in such a way
that when the separators are thrown back for doffing one or more of them comes in
contact with the stop or stops when the ring rail is raised and the series of
separators are thus thrown forward into working position. In order to facilitate
the upward movement of the separators they are formed in such a manner as to
allow them to pass upwards freely, and without obstruction in the notches or
recesses formed in the thread guide boards.
In order that my said invention shall be more readily understood and carried
into practical effect I hereunto annex the accompanying sheet of drawings illus-
trating only such parts of a ring frame as are necessary to show where my
improvements are applied.
Fig. shows on one side of the ring frame a partially filled bobbin of yarn, with
its thread being delivered from the drawing rollers and passing through the thread
board guide to the bobbin on which the yarn is wound during the spinning
operation. My improved separator P is shown at this part of the figure in position
for preventing the threads of any two bobbins interlashing. The downward
projecting shank of the separator always maintains the elongated portion of the
separator blade at a sufficient distance from the ring traveller to enable the rings
being placed in the closest possible proximity to each other which the working of
the travellers upon any two consecutive rings will admit of.
The lower portion of the separator blades are always maintained at a sufficient
distance from the rings and ring rails to enable the attendant to easily finger or
manipulate the ring travellers when piecing up or handling the threads as shown.
At Pin dotted lines at the right hand side of Fig. 1 the separator is shown as
passing partially through the notches in the boards of the thread guide, thereby
illustrating that an unlimited depth of separator can be effectually made use of such
as may be considered most suitable for the highest speeds the spindles are to be run
The lower part of the roller beam is illustrated with a curved attachment or
back stop D against which the upper part of one separator is thrown so as to be
entirely out of the way for doffing purposes. It will readily be seen that an upward
movement of the ring rail on which the separators are mounted will have the effect
of throwing them all into their working position even if only one plate of each series of
separators should come in contact with the curved bracket, projection or other
equivalent, supposing each set of separating plates to be secured to their own
separate shaft.

Fig. 2 shows a plan view of a short portion of ring rail and separator shaft as
partially embedded in the back edge of same, with the separators in the position
which they occupy betwixt the rings in the rail during the spinning operation.

page_text: Having thus particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
Firstly. In a ring spinning frame a ring rail provided at the back edge thereof
with a longitudinal groove and transverse notches or recesses to allow of a separator
shaft carrying a series of separators to be partly embedded or mounted therein.
substantially in the manner as described and illustrated.
Secondly. In a ring spinning frame the combination with each length or section.
of ring rail of a separator shaft carrying a series of separators the whole arranged
and operated substantially in the manner and for the purpose described.
Thirdly. In a ring spinning frame the use of curved brackets or projections D
or the like for actuating and supporting the separators substantially in the manner
and for the purpose described.
Fourthly. In a ring spinning frame the arrangement and construction of the
individual separators mounted as described in Claim 1 so that they will pass through
the notches or recesses between the hinged thread guide boards substantially as.
described and shown.
Fifthly. In a ring spinning frame the several improvements in the arrangement.
and construction of separators substantially as described and illustrated and for the
purpose specified.
