Improvements relating to Spinning Machines.
1, GEORGE FREDERICK REDFERN, of the firm of G. F. Redfern & Co., the
General Patent Office, No. 4, South Street, Finsbury, in the County of Middlesex,
Patent Agents, do hereby declare the nature of this invention (a communication
from abroad by Victor Defraiteur and Armand Maron, of Dison, in the Kingdom
of Belgium) to be as follows:-
This invention relates to spinning machines whereby, upon the thread or roving
becoming too long, which would cause the thread to be irregular in thickness and
twist, it is at the required moment wound up and broken.
In carrying out my invention I employ a shaft or roller covered with plush or
other suitable fabric by which the roving is wound up and broken.
A grooved pulley is placed upon its end and has motion communicated to it by a
cord passing over a grooved pulley during the passage of a cylinder which I term
the tension or pressure wheel over a smooth plate.
A ratchet wheel is keyed upon or formed integral with the tension or pressure
wheel and the latter is provided or not with grooves lined with leather or india
rubber.
A pawl attached to the second named pulley causes it to rotate during the
outward passage of the carriage but not during its return. The smooth plate is
formed with two guides in which are two screws which allow of it being raised when
required upon a plate adapted to the fixed frame of the machine and which can
be drawn backwards or forwards as required. It is secured to the said frame by
two screws. It is also provided with two screws serving to support and adjust the
smooth plate to the proper level.
A lubricating stud or pin supports the tension or pressure wheel, the ratchet,
and the pulley.
A bracket is fixed to the carriage by two bolts and has two guides. On this
bracket is placed the stud or pin which allows of it being raised or lowered and
brought towards the right or left hand according to the distance between the
frame and the side of the carriage.
The perfect drawn threads are wound upon cops as usual and the imperfect
threads are broken and wound upon the shaft during the outward motion of the
carriage.
The smooth plate can be replaced by a rack or conically formed piece etc. and
the cylinder tension or pressure wheel can be replaced by a toothed wheel or
pulley with a hollow space for a cone etc. Also the grooved pullies operating
with a driving cord can be replaced by plain pulleys or toothed wheels and be
actuated by driving bands or chains.
The shaft or roller rotates during the entire outward movement of the carriage
which movement is communicated by a cord passing over the grooved pulley and
over loose pulleys. The cord is fixed by its ends to supports at the front and
back of the machine.
The shaft or roller does not turn during the return owing to the ratchet and
pawl as hereinbefore described.
A support with a slide or guide can be substituted for the hereinbefore described
support in spinning machines having high frames or not having any; the smooth
plate is in this case fixed to the ground.
By this invention the ends of the threads are not allowed to drag upon the
ground and are returned to the cards in a perfectly clean condition which
increases the producing power of the machine besides preserving the cards.

page_text: The roller or shaft can be rotated at a fast or slow rate of speed, for a short
or long time, and commence at any suitable time according to the fineness of the
roving or the quality of the work.

DI BUIFICATION.
Improvements relating to Spinning Machines.
I, GEORGE FREDERICK REDFERN, of the firm of G. F. Redfern & Co., the
General Patent Office, No. 4, South Street, Finsbury, in the County of Middlesex,
Patent Agents, do hereby declare the nature of this invention (a communication
from abroad by Victor Defraiteur and Armand Maron, of Dison, in the Kingdom
of Belgium) and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention relates to spinning machines whereby upon the thread or roving
becoming too long which would cause the thread to be irregular in thickness and
twist it is at the required moment wound up and broken.
In the drawings Figures 1 and 2 are respectively an elevation and a portion of a
plan view of Figure 1 of the apparatus.
In carrying out my invention I employ a shaft C or roller covered with plush or
other suitable fabric by which the roving is wound up and broken when no means
are at hand for setting it right if it become slack. Otherwise thread would be
produced of too great thickness and softness and of irregular twist.
A grooved pulley B is placed upon the end of the roller C and has motion
communicated to it by a cord passing over a grooved pulley R during the passage
of a smooth plate H under à cylinder L which I term the tension or pressure
wheel.
A ratchet wheel K is keyed upon or formed integral with the tension or pressure
wheel L, and the latter is provided or not with grooves covered with leather or
india-rubber.
A pawl J attached to the pulley R causes it to rotate during the outward passage
of the carriage but not during its return. A spring M is fixed to the same pulley
and presses upon the pawl.
The smooth plate H is formed with two guides O, O in which are two screws 01, 01
which allow of it being raised when required upon a plate F adapted to the fixed
frame E of the machine and which can be drawn backwards or forwards as required.
It is secured to the said frame by two screws N, N. It is also provided with two
screws S, S serving to support and adjust the smooth plate H to the proper level.
A lubricating stud or pin Q supports the tension or pressure wheel L, the
ratchet K and the pulley R.
A. bracket P is fixed to the carriage by two bolts and supports another piece V
having two guides. On this bracket is placed the stud or pin which allows of it
being raised or lowered, and brought towards the right or left hand according to
the distance between the frame E and the side of the carriage.
The perfect drawn threads are wound upon cops T as usual and an imperfect
thread T is broken and wound upon the shaft C during the outward motion of the
carriage.
The smooth plate H can be replaced by a rack or conically formed piece or the
like.
The cylinder, tension or pressure wheel L can be replaced by a toothed wheel or
pulley with a hollow space for a cone etc. Also the grooved pulleys B and R
operating with a driving cord can be replaced by plain pulleys or toothed wheels
and be actuated by driving bands or chains.

page_text: Figure 3 represents the shaft or roller C which rotates during the entire outward
movement of the carriage, which movement is communicated to it by a cord passing
over the grooved pulley B and over loose pulleys Z. The cord y is fixed by its
ends to supports at the front and back of the machine.
The shaft or roller does not turn during the return movement owing to the
ratchet and pawl as hereinbefore described with reference to Figures 1 and 2.
Figure 4 represents a support with a slide or guide which can be substituted for
the hereinbefore described support P' in spinning machines having high frames or
not having any the smooth plate H is in this case fixed to the ground.
Figures 5 and 6 represent in elevation the shaft C with a tension and a toothed
wheel B respectively, placed at its end and operating directly during the passage of
the carriage by means of a smooth plate or a rack A which is fixed against a high
frame or the like.
By this invention the ends of the threads are not allowed to drag upon the
ground and are returned to the cards in a perfectly clean condition which increases
the producing power of the machine besides preserving the cards.
The roller or shaft can be rotated at a fast or slow rate of speed, for a short or
long time, and commence at any suitable time according to the fineness of the
roving or the quality of the work.
Figure 7 is an elevation of another arrangement for operating the roller C
covered with suitable fabric.
Figure 8 is a view of this arrangement without the frame E.
The support a, on which is fixed a smooth iron plate d, is fixed by means of two
bolts to the fixed frame E. The support b, (which carries a ratchet-like clutch
mechanism, comprising a pin and spring supporting a toothed wheel ƒ formed
integral with half of the clutch, and a pulley formed integral with the other half
of the clutch i) is fixed at each end of the carriage beneath and at the front by
means of three bolts so that the point of the pin c may be at the same height as the
sliding plate d. This support is always fixed, the adjustment is effected with the
clutch mechanism as well as with the whole of the support a, comprising the sliding
plate, which is raised as desired or moved towards or away from the carriage
according to the distance between the latter and the fixed frame which should be
placed perfectly paralled to the engaging mechanism during the travel of the
carriage.
e,
which
The movement of the cord over the pulley is as follows. It is fixed at the two
ends behind the spinning machine by a pin and at the front by a ratchet
P
gives the desired tension and is placed on a support m which is fixed to the
ground.
When the point of the pin c, during the to and fro movement of the carriage,
grazes or lightly rubs against the smooth plate d, the two half-ratchets or clutch
become engaged thereby causing the toothed wheel f to turn and operate the small
pinion g, by means of a chain, which causes the shaft covered with suitable material
to turn and thereby break the thread or roving which, if not quickly repaired,
would produce defective threads, that is to say, either too thick or too soft
threads.
The support a on the fixed frame E may be moved either backwards or forwards
according to the fineness of the roving to be drawn.
By these means in addition to the regularity and the regular twist of the thread
the waste is no longer drawn over the ground but is gathered up by the shaft which
extends across the spinning machine from end to end whence it can be easily
removed and returned to the cards with the filters intact and in a perfectly clean
state so that the waste of different shades from two adjacent spinning machines
cannot become mixed as nothing falls onto the ground, whereby the product of the
machine is increased.
It will be understood that the improvements are applicable to all kinds of self-
acting spinning machines working carded wool such as self-acting mules, jennys etc.

page_text: 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 :-
1. The improvements relating to spinning machines, serving to wind and break
at a favourable and desired moment the thread or roving which having become too
long would, give rise to the production of a thread of irregular thickness and twist
if the apparatus did not immediately provide against it, substantially as herein-
before described.
2. The improved spinning machines hereinbefore described and illustrated in the
accompanying drawings.
