ABRAM COMBE of Falls Foundry, Belfast in the County of Antrim Ireland
Machinist do hereby declare the nature of this invention to be as follows :-
This invention relates to twisting frames in which the yarn is supplied to the twist
bobbins by means of drawing or hauling pullies carried by the flyers.
In these twisting frames the flyer is driven at a uniform speed and the haul pullies
in or on the flyer are driven through a sun and planet motion by a pulley running at
a different speed and thereby draw the twist or thread into the flyer.
Between the flyer and the creel there is a tube or eye for the purpose of gathering
the single yarns together as they come from the creel bobbins and forming the
twisted thread.
The yarns are guided to this tube or eye by a ring with nicks in the outer edge
which make the yarns enter the tube radially and also prevent the twist from running
back to the creel.
The amount of twist given to the thread is regulated by the difference between the
speed of the flyer and of the pulley which drives the central wheel of the haul
pullies.
These improvements consist
:
First in having a novel arrangement for driving each flyer separately in such a
manner that it can be started or stopped independently and also that the amount of
twist given to the thread can be altered in each flyer without affecting any other
flyer.
Second in the combination with the starting and stopping arrangement of a
contrivance for carrying the tube or eye in which the twist is formed in such a
manner that when the tube or eye becomes choked it immediately liberates the
stopping motion and stops the flyer it is in connection with.
Third in the combination with the said starting and stopping arrangement of a
contrivance for measuring the length of yarn given off by the creel the measuring
apparatus being so arranged that when any required length has passed it immediately
actuates the stopping motion of the flyer it is connected with.

page_text: The measuring apparatus may also be so arranged that one apparatus will stop all
the flyers in the frame at the same time.
The arrangement for driving each flyer separately consists in connecting the two
pullies which drive respectively the pulley on the flyer and the pulley on the central
wheel of the haul pullies with a friction plate or plates which are held in contact
with their driving discs by means of a spring that revolves with the friction plate so
that there is no extra friction on the bearings caused by the pressure required to keep
the friction plates and driving discs in contact.
The friction plates are withdrawn from contact with the driving discs by compressing
the spring alluded to above by means of levers. These levers are put into action by
means of a spring or weight held by a trigger and this spring or weight can be
liberated by the hand of the attendant by the action of the mechanism which carries
the eye or by the measuring apparatus acting on the trigger so that the flyer can not
only be stopped at will but it also stops automatically when the eye chokes or when the
desired length is twisted.

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:
This invention relates to twisting frames in which the yarn is supplied to the twist
bobbins by means of drawing or hauling pullies carried by the flyers.
In these twisting frames the flyer is driven at a uniform speed and the haul pullies
in or on the flyer are driven through a sun and planet motion by a pulley running at
a different speed and thereby draw the twist or thread into the flyer.
Between the flyer and the creel there is a tube or eye for the purpose of gathering
the single yarns together as they come from the creel bobbins and of forming the
twisted thread.
The yarns are guided to this tube or eye by a ring with nicks in the outer edge
which make the yarns enter the tube radially and also prevent the twist from running
back to the creel.
The amount of twist given to the thread is regulated by the difference between the
speed of the flyer and of the pulley which drives the central wheel of the haul
pullies.
These improvements will be understood from the following description reference
being made to the three sheets of drawings herewith in which the same letters and
figures of reference always apply to the same or like parts.

carrying the forming tube or eye and its connections with the stopping apparatus.
These improvements consist First in having a novel arrangement for driving each
flyer (a) separately in such a manner that it can be started or stopped independently
and also that the amount of twist given to the thread can be altered in each flyer (a)
without affecting any other flyer.
The arrangement for driving each flyer (a) separately consists in connecting the
two pullies (6 b¹) which drive respectively the pulley (a¹) on the flyer (a) and the
pulley (a) on the central wheel of the haul pullies (a³) with a friction plate or
plates (c) which are held in contact with their driving discs (d) by means of a
spring (c) that revolves with the friction plate (c) so that no extra friction on
bearings is caused by the pressure required to keep the friction plates (c) and driving
discs (d) in contact.
In Fig. 3 and
the friction plates (c) are withdrawn from contact with the
driving discs (d) by compressing the spring (c¹) by means of levers (e), these

page_text: levers (e) are put into action by means of a cam (f) working between the ends of
the levers (e) farthest from the friction plates (c). The cam (f") is attached to a
shaft (f) on which is a weighted lever (f) held in a horizontal position by a weighted
trigger (g) acting upon a finger projecting from the shaft f¹. When the trigger (g)
is relieved the weighted lever (f) swings down and causes the shaft (f) with the
cam (f) on it to make a quarter turn the cam (f) thereby forces the ends of the
levers (e) farthest from the friction plates (c) apart and the ends nearest the friction
plates (c) together and thereby compresses the spring (c) and withdraws the friction
plates (c) from contact with the driving discs (d).
In Fig. 5 another arrangement of friction plate (c) and driving disc (d) is shewn
in which the driving pullies (b) are placed upon a vertical spindle (6) driven by
geering from a horizontal shaft. In this arrangement the friction plate (c) is moved
out of contact with the driving disc (d) by means of-a pin (63) inside the spindle (62)
in contact with a key (c) in the friction plate (c) and acted upon by a weighted
lever (p) held out of contact by the wire (w) which is connected to the same
trigger (g) mentioned in foregoing description of Fig. 3 and 4 and illustrated in
supplemented Fig. 10 and 11.
The trigger (9) can be liberated by the hand of the attendant at any time it is also
controlled by the mechanism which carries the eye and by the measuring apparatus
so that the flyer can not only be stopped at will but also stops automatically when the
eye () chokes or when the desired length of yarn has passed from the creel (k) to the
flyer (a) to be twisted.
Second in the combination with the starting and stopping arrangement of a
contrivance for carrying the tube or eye (i) in which the twist is formed in such a
manner that when the tube or eye (i) becomes choked it immediately liberates the
stopping motion and stops the flyer (a) it is in connection with.
This contrivance consists in attaching the eye (i) to a lever (h) on which is a
runner (¹) that rests against a weighted bell crank lever (1) one arm of this lever (1)
is made with a suitable recess in which the runner (¹) rests when in its working
position but when the eye (i) becomes choked so that the yarns do not pass freely
through it the twist draws down the eye (i) causing the runner (h) to force back the
bell crank lever (1) the bell crank lever (!) then comes in contact with the trigger (9)
which liberates the stopping motion already described and stops the flyer (a).
:
Third in the combination with the starting and stopping arrangement of a
contrivance for measuring the length of yarn given off by the creel (k) the measuring
apparatus being so arranged that when any required length has passed it immediately
actuates the stopping motion of the flyer it is connected with.
This is accomplished by passing the yarn as it goes from the creel (k) to the
flyer (a) over a measuring drum (m) which is driven by the yarn and which through
suitably proportioned worms and wheels communicates motion to a disc or dial (n).
On the edge of the dial (n) is a nick or recess (n³) and resting upon the edge of the
dial (n) is a small lever (n³) connected by a spindle (n³) to a weighted lever (n).
When the dial (n) revolves so far as to bring the nick (n¹) in the edge of the
dial (n) under the small lever (n) the end of the latter falls into the nick (n¹) by
the action of the weighted lever (n') which communicates through a wire (n) with
the trigger (9) and liberates the stopping motion as before described and so stops the
flyer (a) it is connected with.
To set the measuring apparatus the dial (n) is turned back on its spindle until the
nick (n) is such a distance from the end of the small lever (n²) that it requires
the measuring drum (m) to make the desired number of revolutions before it turns the
dial (n) sufficiently to bring the nick (n) under the lever (22) again. To facilitate
resetting a small stopper or saddle (n°) is used which can be attached to any part of
the rim of the dial (n) and the dial (n) is set by turning it till the saddle (n) comes
into contact with the point of the lever (n³) the distance between the edge of the
saddle (n) and the nick (n) regulating the length of yarn passing over the measuring
apparatus before the flyer (a) stops.
The measuring apparatus may also be so arranged that one apparatus will stop all

page_text: the flyers in the frame at the same time by simply connecting the wire (n³) to the
retaining catch of a weighted belt fork which on being liberated will move the
driving belt on to the loose pulley.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is
(1)-The general arrangement of the twisting frame herein described and
illustrated.
(2) The arrangement illustrated and described for driving twisting flyers
independently.
(3) The combination of the automatic stop motion with the contrivance described
for carrying the tube or eye in which the twist is formed in such a manner that when
the tube or eye becomes choked the flyer is stopped.
(4) The combination of the automatic stop motion with the measuring apparatus
described in such a manner that when a required length is twisted the flyer is
stopped.
