I, JOHN CLAYTON MEWBURN of the Firm of J. C. Mewburn and Ellis of 55 and 56
Chancery Lane, in the County of London, Chartered Patent Agents, do hereby
declare the nature of this invention to be as follows;-
The improvements in spinning machines which form the subject of the present
invention have been designed with especial reference to throstle frames, but they
are also applicable to spinning machinery in general, with wet or dry frames,
and to cop winding machines. The improvements will be fully understood from
the following description of apparatus embodying the same.
The sliver or roving is led in the ordinary way from the bobbin on the creel
at the top or back of the machine to a feed roller, and thence to a drawing roller,
where it is drawn in any known manner. On leaving the drawing roller the
thread passes through the top of the flyer and is led thence through a small guide
ring soldered to one of the arms of the flyer, becoming finally wound upon the
bobbin. This bobbin is rotated by the drawing action of the thread itself. The
difference in speed of the bobbin and of the flyer allows of the winding being effected
this being obtained by the tension of a weighted cord, chain or the like, and by the
friction of the bobbin upon its spindle.
The flyer is directly actuated from the drum of the machine by means of a small
pulley keyed upon the sleeve to the bottom of which the flyer is screwed. This
sleeve is supported by a fork fixed to the frame of the machine, and its upper end
passes through an aperture in a guard plate, which is preferably adapted to be lifted
to facilitate lubrication. The object of this plate is to prevent the threads which
break upon leaving the drawing roller from becoming entangled and wound around
the sleeve of the small pulley before described. There is also another plate pierced
with square holes, through which the attendant may pass a wooden key or wedge
in order to stop the motion of the flyer when it is necessary to piece the thread."
The bobbin, unlike those hitherto employed, has a collar or shoulder in the under
face of which is cut a dovetail groove which engages with a tenon or dovetail
of corresponding form upon the top face of a pulley carried below on the same
spindle, and this pulley is thus driven by the bobbin. The object of this arrange-
ment is to prevent the bobbin from rising or remaining lifted when the vertically
reciprocating mechanism begins to descend. The said pulley is formed with
two circumferential grooves in the lower of which the weighted cord or chain
engages. The object of the upper groove is to receive a few turns of thread at
the end of the winding, and at the last travel of the bobbin. This winding of a
few turns of thread on the pulley avoids the necessity of the attendant herself
having to wind the thread upon the fresh bobbin as hitherto. As the thread has
remained attached to the grooved pulley, it becomes automatically wound upon

page_text: the fresh bobbin when the machine is again set in operation; thus a great saving
of time is effected.
To attain this result at the last upward travel of the winder, the vertically re-
ciprocating plate or lifting rail is raised, say about 15 millimetres above its normal
highest point. With this object there is affixed to the extremity of the shaft which
carries the chain pulleys a lever, say about 50 centimetres long. At the required
raoment the attendant lifts this lever with one hand while with the other she throws
the machine out of gear. By lifting the lever the reciprocating plate or lifting
rail is raised the 15 millimetres necessary to bring the upper groove of the pulle
opposite the eye of the flyer.
When the reciprocating plates are at the highest point of their travel it is im-
Fessible to withdraw the bobbin, as it would come against the sleeve of the flyer.
To enable this to be effected the reciprocating plates are according to the present.
invention made capable of a forward pivotting movement, preferably by the follow-
There is fixed under the beam of the frame a sleeve through which
passes a shaft having a lever keyed on its forward extremity, and at its rear
extremity and at right angles to the said lever, a second lever. By giving a
quarter turn to the forward lever from left to right, the rear lever is brought from
its normal horizontal position to the vertical position. The rear lever being say
4 or 5 centimetres longer than the space comprised between the axis of the two
levers and a bar immediately below the reciprocating plate or lifting rail, this bar
is lifted, and turning upon a pivot at its forward end brings the reciprocating
plate and bobbin into an oblique position, in which the bobbin may readily be
removed. An abutment or stop is provided beneath the bar for the purpose of
maintaining the reciprocating plate in its normal position as soon as this is
reassumed.
The operation of these parts is very simple. When the bobbin is full and is
effecting its last ascensional travel, the attendant presses upon the lever on the shaft
which carries the chain pulleys and at the same time throws the machine out of gear
so that the thread may become wound upon the upper groove of the pulley before
described. As soon as the machine is stopped the attendant gives a quarter turn
to the lever before described to cause the reciprocating plate to pivot. The bobbin
being replaced by a fresh one, she then allows the lever upon the chain pulley
shaft to fall, thus bringing the bobbin to the working position, and puts the machine
again in gear.
If necessary the flyer may be mounted in ball bearings.
The advantages obtained by this invention are:-Economy in lubrication and
motive power; greater production, because the machine can work at a much
greater speed and the wound bobbins can be removed much more rapidly; greater
output on account of the suppression of the waste due to the vibration of the
spindles, and by the automatic attachment.

I, JOHN CLAYTON MEWBURN of the Firm of J. C. Mewburn and Ellis of 55 and 56
Chancery Lane, in the County of London, Chartered Patent Agents, do hereby

page_text: declare the nature of the said invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:-
The improvements in spinning machines which form the subject of the present
invention have been designed with especial reference to throstle frames, but they
are also applicable to spinning machinery in general, with wet or dry frames,
and to cop winding machines. The improvements will be fully understood from
the following description of apparatus embodying the same, and by reference to the
accompanying drawings, in which Figure 1 is a side elevation of the apparatus
partly in section, Fig. 2 a side elevation of the parts, showing the means of tem-
porarily raising the vertically reciprocating plate or lifting rail above its normal.
highest position for the purpose hereinafter described, and Figure 3 is a front view
of the shaft 0 and its levers P, Q, hereinafter referred to, showing the lever Q
in the raised position. Fig. 4 is a side view of the lower end of the flyer as seen
at right angles to Fig. 1.
The sliver or roving is led in the ordinary way from the bobbin on the creel
at the top or back of the machine to feed rollers A, and thence to drawing rollers Bb,
where it is drawn in any known manner. On leaving the drawing rollers B b the
thread passes through the top of the flyer and is led thence through a small guide
rin soldered to one of the arms of the flyer, becoming finally wound upon the
hobbin. This hobbin is rotated by the drawing action of the thread itself. The
difference it speed of the bobbin and of the flyer allows of the winding being effected
this being obtained by the tension of a weighted cord, chain or the like c, and by
the friction of the bobbin upon its spindle. The weighted cord also serves, in
ciunction with the pulley II hereinafter described to prevent the bobbin rising
o remaining raised when the lifting rail begins to descend.
The flyer is directly actuated from the drum D of the machine by means of
a small pulley E keyed upon the sleeve to the bottom of which the flyer is screwed,
This sleeve is supported by a fork F fixed to the frame of the machine and its
upper end passses through an aperture in a guard plate G, which is preferably
adapted to he lifted to facilitate lubrication of the flyer sleeve, this being effected
by introducing oil at g. The object of the plate G is to prevent the threads which
break upon leaving the drawing roller from becoming entangled and wound around.
the sleeve of the small pulley E. There is also another plate G pierced with square
hole, through which the attendant may pass a wooden key or wedge in order to stop
the motion of the flyer when it is necessary to piece the thread.
The bobbin, unlike those hitherto employed, has a collar or shoulder in the under
face of which is cut a dovetail groove which engages with a tenon or dovetail of
corresponding form upon the top face of a pulley H carried below on the same.
spindle, and the pulley H is thus driven by the bobhin. The object of this
arrangement is to prevent the bobbin from rising or remaining lifted
when the vertically reciprocating mechanism begins to descend. The
pulley His formed with two circumferential grooves in the lower of which the
weighted cord or chain e engages. The object of the upper groove is to receive a
few turns of thread at the end of the winding, and at the last travel of the hobbin,
as hereinafter described. This winding of a few turns of thread on the pulley H
avoids the necessity of the attendant herself having to wind the thread upon the
fresh bobbin as hitherto. As the thread has remained attached to the grooved
pulley H, it becomes automatically wound upon the fresh bobbin when the machine
is again set in operation; thus a great saving of time is effected.
To attain this result at the last upward travel of the winder, the vertically
reciprocating plate or lifting rail M is raised, say about 15 millimetres above its
normal highest point. With this object (see Figure 2) there is affixed to the
extremity of the shaft K which carries the chain pulleys a lever L, say about
50 centimetres long. At the required moment the attendant lifts the lever L with

page_text: one hand, while with the other she throws the machine out of gear. By lifting
the lever L, the reciprocating plate or lifting rail M is raised the 15 millimetres
necessary to bring the upper groove of the pulley H opposite the eye of the flyer.
When the reciprocating plates M are at the highest point of their travel, it is
impossible to withdraw the bobbin as it would come against the sleeve of the flyer.
To enable this to be effected, the reciprocating plates M are according to the present
invention made capable of a forward pivotting movement, as shown in dotted lines
in Figure 1, preferably by the following means. There is fixed under the beam X
of the frame a sleeve N through which passes a shaft having a lever l' keyed on
its forward extremity, and at its rear extremity and at right angles to the said lever P
a second lever Q. By giving a quarter turn to the lever P from left to right the lever Q
is brought from its normal horizontal position to the vertical position. The lever Q
being say 4 or 5 centimetres longer than the space comprised between the axis of the
shaft and a pivotted bar ml situated immediately below the reciprocating plate or
lifting rail M, this bar m" is lifted by the lever Q, and turning upon the pivot R,
brings the reciprocating plate M and bobbin into an oblique position as shown,
in which the bobbin may readily be removed. An abutment or stop S is provided
beneath the bar for the purpose of maintaining the reciprocating plate M in its
normal position as soon as this is reassumed.
Another way of allowing of removal of the bobbins is to impart to the vertically
reciprocating plates or lifting rails M, at any point of their vertical travel, a move-
ment of translation by pulling them by hand clear of the flyers. Stops should be
provided to limit this movement and also the corresponding return movement.
The operation of the apparatus is very simple. When the bobbin is full, and
is effecting its last ascensional travel, the attendant lifts the lever L before described
and at the same time throws the machine out of gear, so that the thread may become
wound upon the upper groove of the pulley H. As soon as the machine is stopped,
the attendant gives a quarter turn to the lever P to cause the reciprocating plate
to pivot under the action of the lever Q. The bobbin being replaced by a fresh one
the attendant then allows the lever L to fall, thus bringing the bobbin to the
working position, and puts the machine again in gear.
If necessary the flyer may be mounted in ball bearings.
The advantages obtained by this invention are, Economy in lubrication and
motive power by virtue of the suppression of the spindles; greater production,
because the machine can work at a much greater speed and the wound bobbins
can be removed much more rapidly; greater output on account of the suppression
of the wa-te due to the vibration of the spindles and by the automatic attachment.
Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me and in what manner the same is to be performed I
declare that what I claim in respect of spinning and winding machines is
1. A cord or chain of suitable tension, in combination with a pulley connected
with the bobbin or other receiver for the purpose of regulating the speed of the
bobbin and assisting the winding operation substantially as described.
2. The combination of a bobbin or the like, a pulley carried below said bobbin
upon the same spindle, said pulley being so connected with said bobbin as to be
driven thereby, and a cord or chain, said cord or chain being in tension and
engaging with said pulley all substantially as and for the purposes herein before
described and represented in the accompanying drawings.
3. The combination with a bobbin or the like, of an extension separate therefrom
and capable to receive the thread after the bobbin is filled, so as to enable the
immediate and automatic winding of the thread on to an unfilled bobbin, sub-
stantially as described.
4. The combination with a bobbin or the like, of an extension separate therefrom
and capable to receive the thread after the hobbin is filled, and of means for tem-

page_text: porarily raising same to the required extent to enable the extension to receive
the thread after the bobbin is filled, substantially as and for the purpose described.
5. The combination of a pivotting bar such as m¹l with means for imparting
a pivotting movement thereto to enable the bobbin to be withdrawn at the highest
point of its travel, substantially as described and shown in Figs. 1 and 3.
6. The combination of the vertically reciprocating plates or lifting rails with
means of imparting to them at any point of their vertical travel, a movement of
translation instead of the pivotting movement herein before-described, for the
purpose of allowing of removal of the bobbins, all substantially as hereinbefore
described.
7. The combination and arrangement of parts described and shown in Figure 1
of the accompanying drawings.
