WALTER ALFRED BARLOW, of 6, St. Paul's Churchyard, London, Patent Agent
and Engineer. " IMPROVEMENTS IN SPINNING AND IN APPARATUS THEREFOR.'
A cominunication from abroad by Robert Loeffel, of Paris, France.
This Invention relates to improvements in continuous spinning machines known
as "ring throstle or Booth Sawyer principle.
"
These new machines have the advantage of suppressing the flyers of the spindles
and replacing them by a fixed ring, around which travels a smaller split or divided
ring or carrier, which latter is secured to the fixed ring by means of a groove, or
simply retained by a corresponding flange and web.
The imperfect mounting of the spindles of this class of machines necessitates that
the spindles be of large diameter in order to avoid vibration, and thereby is
necessitated the employment of very heavy tubes which are consequently expensive
and which renders the use of the products of ring throstle spinning disadvan-
tageous for export and even for transport to a distance, and necessitates that
weavers who employ them are compelled to change the spindles of their machinery.
To obviate these inconveniences the ordinary spindle of the self acting class is
according to this Invention modified to substitute it for the spindle of the con-
tinuous ring throstle machine, and thereby may be employed n ring of smaller
dimensions, and have applied to the movement of the said ring an eccentric of such
form that the thread arrives at the top of the guide and redescends rapidly, forming
on account of the high speed an elongated spiral, that is to say, the filling of the
spool is effected in the same manner as in the " self-acting."

page_text: To effect the practical application of this there has been combined a new arrange-
ment, which forms the basis of this Invention. This new spindle is fitted so us to
turn continually in a footstep always filled with oil, and the driving apparatus is
placed between the collar of the spindle and the foot, whereby it may be operated
from below its centre of gravity as much as possible, whereby the vibration is
obviated, and two small grooves are provided in the said collar as reservoirs for
oil for lubrication at this point.
This arrangement of the spindle will allow of its being driven by bevil or heli-
coidal gearing, and consequently to avoid all slipping, and these gear wheels are
made of "pyrophile or papier maché, whereby great softness of movement is
obtained.
"
There may also be employed for purpose of driving wharles of vulcanite or
hardened indin rubber driven by a fine iron, wire cord, or a steel band, which
modes of driving for the said purpose it is intended to claim.
A delicate point in continuous spinning machines (ring throstle) is the joining
of the thread, the operator having to stop the spindle to join the thread and then
to pass it into the ring, and the difficulty of such an operation is well understood
if the operator has to retain the spindle immovable at the same time in one
hand.
For stopping the spindle an arrangement is employed which may be operated
by the knee, and consequently leaving both hands free for the purpose of joining
the thread.
The footstep of the spindle is enclosed in a box fixed by a female screw on the
spindle rail. When the ordinary driving wharl is employed the said wharl is
constructed according to this Invention of hard india rubber or papier maché,
and is made with a circular plate against which the stop spring may be pressed as
required.
According to this Invention the driving device is placed between the spindle
collar and the footstep, and never above the collar. This novel arrangement gives
great stability and prevents all vibration. With this new spindle there may be
employed tubes or spools, as light as is desired; for instance, in the practical
working of this Invention tubes as light as 2000 to the pound avoirdupois have
been employed.

WALTER ALFRED BARLOW, of 6, St. Paul's Churchyard, London, Patent Agent
and Engineer. "IMPROVEMENTS IN SPINNING AND IN APPARATUS THEREFOR"
A communication from abroad by Robert Loeffel, of Paris, France.
This Invention relates to improvements in continuous spinning machines known
as "ring throstle or Booth Sawyer principle.
"
These new machines have the advantage of suppressing the flyers of the spindles
and replacing them by a fixed ring, around which travels a smaller split or divided
ring or carrier, which latter is secured to the fixed ring by means of a groove or
simply retained by a corresponding flange and web.
The imperfect mounting of the spindles of this class of machines necessitates that
the spindles be of large diameter in order to avoid vibration, and thereby is
necessitated the employment of very heavy tubes, which are consequently expensive
and which renders the use of the products of ring throstle spinning disadvantageous
for export and even for transport to a distance, and necessitates that weavers who
employ them are compelled to change the spindles of their machinery.
To obviate these inconveniences the ordinary spindle of the self acting class is
according to this Invention modified to substitute it for the spindle of the con-
tinuous ring throstle machine, and thereby may be employed a ring of smaller
dimensions (about 35 millimetres or 1 inches) and have applied to the movement
of the said ring an eccentric of such form that the thread when it arrives at the
top of the cop and redescends rapidly, forming on account of the high speed an
elongated spiral, that is to say, the filling of the spool is effected in the same
manner as in the "self-acting."
To effect the practical application of this there has been combined a new arrange-
ment, which forms the basis of this Invention. This new spindle is fitted so as
to turn continually in a foot-step always filled with oil, which allows of its being
driven at great rapidity, and the driving apparatus is placed between the collar of
the spindle and the foot, whereby it may be operated from below its centre of
gravity as much as possible, whereby the vibration is obviated, and two small
grooves are provided in the said collar as reservoirs for oil for lubrication at this
point.
This arrangement of the spindle will allow of its being driven by bevil or
helicoidal gearing, and consequently to avoid all slipping, and these gear wheels
are made of "prophile" or papier maché, whereby great softuess of movement is
obtained.
There may also be employed for this purpose of driving wharles of vulcanite or
hardened india rubber driven by a fine iron wire, cord, or steel band, which
modes of driving for the said purpose it is intended to claim as applied to this class
of machines.
A delicate point in continuous spinning machines ("ring throstle ") is the joining
of the thread. The operator having to stop the spindle to join the thread and
then to pass it into the ring, and the difficulty of such an operation is well under-
stood if the operator has to retain the spindle immoveable at the same time in one
hand.
For stopping or holding the spindle an arrangement is employed which may be
operated by the knee, and consequently leaving both hands free for the purpose of
joining the thread.

page_text: In order that the said Invention may be well understood I will proceed to
describe the same in reference to the annexed Sheet of Drawings, wherein the
apparatus is represented about full size.
In Fig. 1 A is the spindle, which is about the size of a spindle of an ordinary
"mule jenny;" it rests in the footstep B, enclosed in a box C, covered by a cover D,
through which the spindle foot passes, the box C being fixed by a screw nut on the
spindle rail P. The footstep B is pierced with sinall holes, whereby its interior is in
communication with the box C in such wise that the box being full of oil the
footstep will also receive and the foot of the spindle turns in oil for purpose of
lubrication. The collar E is screwed into a piece F, and is provided with two
grooves full of oil, which also affords perfect lubrication to this part.
In this Fig. 1, the driver of the spindle is represented at H of ordinary kind by
pulley and cord, but it may be modified us before described; and further, the said
pulley or wharl may be made in hardened india rubber or pyrophile; it carries or
is made with a plate or shoulder h, against which a spring R may press at will.
This spring is arranged in such wise that if the operative presses it with his knee
sufficient friction will be produced to arrest the spindle.
In the improved spindle, constructed according to this Invention, the driver is
placed between the collar and the footstep and never above the collar, which now
arrangement gives to the system great stability and destroys all vibration, which
is one of the most important points of this patented combination; also with this
new spindle there may be employed very light cop tubes; it may be remarked that
tubes as light as 1800 to the pound avoirdupois have been employed. The tube
is shown in place at K. The fixed ring M by its rising and falling movement gives
the form to the cop.
Fig. 2 shows an arrangement of gearing in which the arresting of the spindle
is obtained by the means above described, with the addition of a friction cone.
Fig. 3 shows another construction in which the arrest is effected as in Fig. 2,
but the rotation is given by helicoidal gearing; Fig. 4 is detached view of ring,
which may be made in glass or crystal, which will prevent considerable loss.
Thus it will be seen that this improved construction of apparatus presents the
following considerable advantages :—
1st. It will not be necessary for the weaver to change the spindles of his bobbin
frames.
2nd. Hitherto it has not been possible to utilize the products of these machines
for exportation, and the spinner wishing to employ them could not do so unless
their works were in the immediate neighbourhood of the weavers because of the
excessive weight of the paper tubes. This Invention however will allow of the
goods being furnished freed from the tube, and consequently they may be sent to
a distance.
3rd. In consequence of the great lightness of the tubes it is possible to steam the
threads in order to fix the torsion and render the threads less dry.
4th. The light tube completely traversing the bobin prevents the loss in
weaving either from entangled bobbins or the ends of bobbins having no tubes or
having the ends pasted.
5th. This system of collar and footstep allowing of the driving of the spindle
either by cord, or by gearing, or helicoidal or worm gearing between the collar and
the footstep will prevent the vibration produced by the application of the driving
means above the collar.
6th. The device for arresting the spindle by a spring leaves the operativo perfect
freedom for his hands during the joining of a broken thread.
7th. With this construction of collar and footstep 7000 revolutions may be readily
httained without producing vibration.
8th. The footstep will not require to be supplied with oil more than once in two
months at most, and the foot of the spindle will suffer no appreciable wear in

page_text: consequence of its efficient lubrication. The collar needs to be lubricated but once,
as the grooves in it will retain the oil.
9th. As the footsteps and collars can be displaced it is always possible to exactly
place the rings in the centre at the top and the bottom which is essential for good
working.
I claim, 1st, the new continuous spinning apparatus thus modified, the elements
whereof have been herein set forth and described, and constituting an industrial
machine capable of giving results hitherto unattained.
2nd. The construction of the rings in glass or crystal, as described and illustrated
in Fig. 4.
In witness whereof, I, the said Walter Alfred Barlow, have hereunto set my
hand and seal, this Fifth day of November, in the year of our Lord One
thousand eight hundred and seventy nine.
