Improvements in Split Drum Winding Frames.
We, SAMUEL HERBERT BROOKS, Machine Maker, and JoшN SAMUEL BROOKS,
Sub Manager, both of the Union Iron Works, West Gorton, Manchester in the
County of Lancaster, do hereby declare the nature of this invention to be as
follows:-
In this class of winding frame in which the yarn is directed or guided onto
the spool by a diagonal split in the drum it is very desirable in case of the breakage
of the yarn that the stop motion should act before the broken or free end of the
yarn reaches the spool.
In order to obtain a long length of yarn between the detector wires of the stop
motion and the drum we have tried carrying the ends of yarn over guide pulleys
or rollers above the drum and down again under other guide pulleys to direct
the yarn into the split in the drum but this we have found objectionable in
practice as when the end broke at the top of the drum or between the second
guide roller and the spool the weight of the yarn was such as to hold the detector
wire out of contact with the wiper shaft and allow the frame to continue running.
This method of carrying the yarn has consequently had to be discarded and
the end passed direct from the detector wire to the drum.
Further in this class of winding frame we have found that with the existing
arrangement of the spool carrying lever and the steel guide plate or its equivalent
the position of that portion of the periphery of the spool which receives the point
of winding is constantly varying relatively to the edge of the steel guide plate
or its equivalent and thus causes a variation in the tension on the yarn.
We now find that by re-arranging the position of some of the operative parts
of the machine and altering the construction of some of such parts we can obtain
the advantage of a long length of yarn without the disadvantage of a weight of
yarn sufficient to prevent the stop motion acting and also practically overcome
the difficulty of the varying position of the point of winding on the spool in its
relation to the edge of the guide plate or its equivalent.
The split drum is constructed and mounted in the usual way and we transfer
the spool carrying lever from its present position above the drum and pivot it
on the under side of the drum so that the yarn must traverse the slit of the
drum in a downward direction and in such a position that as the spool fills the
point at which the yarn is wound thereon shall always maintain the same relative
position to the winding drum.
The steel guide plate or its equivalent is also transferred from above to below
the drum and is affixed to the beam.
The spool carrying lever is pivoted below the drum upon a pivot inside the
vertical plane of the drum axis so that the relative position of the periphery of
the spool to the steel guide as it fills or increases in size shall remain the same
and the point of winding not alter in any appreciable or detrimental manner.
The spool carrying lever is also of a curved or slightly angular or other suitable

page_text: form with an upper arm, or member to carry the spool and a lower arm or member
to carry a weight. It is so placed that the weight or leverage increases at the
weighted end as the spool fills and increases in weight at the other end so that
an equal pressure upon the drum is maintained throughout the winding.
It is necessary that the yarn must traverse the slit in the drum to a sufficient
depth not to be thrown out by the motion of the drum we therefore carry the yarn
up from the detector guide over a guiding roller at the top so placed in relation
to the front of the drum as to allow of sufficient angle being given to the thread
as will prevent it flying out of the slit of the drum. A second guide may be
necessary to prevent the yarn touching the face of the drum.

brake would be carried on a pivoted arm actuated by a forked or other lever by
which it would be thrown into contact with the spool between it and the steel
guide plate when the detector mechanism throws the drum out of contact with
the spool.
The essential features of the invention are
1st. The arranging of the spool carrying lever and the steel guide plate or
its equivalent so that the spool may be wound below the drum and the thread
carried up from the detector mechanism over a top carrier and passed down through
the drum to the spool to give sufficient length of yarn to prevent ends being wound
onto the spool and at the same time not so much as will over weigh the detector
wire and prevent them acting on the breaking of a thread.
2nd. The arranging of the steel guide plate or its equivalent and the spool
carrying lever in such a manner that the relative position of the periphery of
the spool to the steel guide plate as it fills or increases in size shall remain the
same so that the point of winding will not alter in any appreciable or detrimental
manner.

Improvements in Split Drum Winding Frames.
We, SAMUEL HERBERT BROOKS, Machine Maker, and JOHN SAMUEL BROOKS,
Sub Manager, both of the Union Iron Works, West Gorton, Manchester, in the
County of Lancaster, 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:-
In this class of winding frame in which the yarn is directed or guided onto
the spool by a diagonal split in the drum, it is very desirable in case of the breakage
of the yarn that the stop motion should act before the broken or free end of the
yarn reaches the spool.
In order to obtain a long length of yarn between the detector wires of the stop
motion and the drum we have tried carrying the ends of yarn over guide pulleys
or rollers above the drum and down again under other guide pulleys to direct
the yarn into the split in the drum but this we have found objectionable in
practice as when the end broke at the top of the drum or between the second
guide roller and the spool the weight of the yarn was such as to hold the detector
wire out of contact with the wiper shaft and allow the frame to continue running.
This method of carrying the yarn has consequently had to be discarded and
the end passed direct from the detector wire to the drum.

page_text: Further in this class of winding frame we have found that with the existing
arrangement of the spool carrying lever and the steel guide plate or its equivalent
the position of that portion of the periphery of the spool which receives the point
of winding is constantly varying relatively to. the edge of the steel guide plate
or its equivalent and thus causes a variation in the tension on the yarn.
We now find that by re-arranging the position of some of the operative parts
of the machine by transferring them from above to the underside of the split
drum and altering the construction of some such parts we can obtain the advan-
tage of a long length of yarn without the disadvantage of a weight of yarn
sufficient to prevent the stop motion acting and also practically overcome the
difficulty of the varying position of the point of winding on the spool in its relation
to the edge of the guide plate or its equivalent.
The invention will be fully described with reference to the accompanying
drawings in which sufficient of a winding frame is shown to illustrate the im-
provements.

in side elevation.
Fig. 2. Front elevation of the steel guide plate E.
Fig. 3. Side elevation of same
The split drum A is constructed, mounted and operated in the usual way.
By our present invention we pivot the spool carrying lever B on the under-
side of the split drum, A (instead of above it as has hitherto been customary) and
cause the yarn C to traverse the slit in the drum in a downward direction (as
indicated by the arrow heads) the spool carrying lever B being pivoted in such
a position that as the spool 1) fills the point thereon at which the yarn commences
to wind or with which it first comes in contact as it leaves the slit shall always
maintain the same relative position to the winding drum.
The steel guide plate E or its equivalent we also now place below the drum.
It is adjustably bolted to a fixed bracket e and is so placed that the top edge el rests
between the yarn on the spool D and the surface of the winding drum A. The
top edge el is bent over as shown in Fig. 3.
The spool carrying lever B is pivoted upon a rod or bar F placed below the
winding drum A and inside the vertical plane of its axis so that the relative
position of the periphery of the spool D to the steel guide plate E as it fills or
increases in diameter shall remain the same and the point of winding relatively
to the winding drum and guide shall not alter in any appreciable or detrimental
manner.
The spool carrying lever B is curved or slightly angular or of other suitable
form with an upper arm or member b to carry the spool D and a lower arm or
member to carry a weight W. It is so shaped or placed that the weight or
leverage increases at the weighted end b as the spool D fills and increases in
weight at the other end b so that an equal pressure upon the drum A is maintained
throughout the winding.
To the spool carrying lever B is pivoted a handle or lever B' to hold the lever B
away from winding dram A when required either to throw the spool out of contact
or piece up an end. The spool carrying lever is pulled away from the drum
sufficient distance until the pivoted lever latches onto the beam.
When it is required to release the pivoted lever the front part of same must
be pressed down which releases it and allows the spool carrying lever B to bring
the spool in contact again with the drum A.
It is necessary that the yarn C must traverse the slit in the drum to a sufficient
lepth not to be thrown out by the motion of the drum, we therefore carry the
arn C up from the detector guide G over a guiding roller H at the top placed
ufficiently far behind the front of the winding drum A as to prevent the yarn
r thread C flying out of the slit in the drum. A second guide K may be
ecessary to prevent the yarn touching the face of the drum.
An auxiliary brake not shown on the drawings may be applied to stop the

page_text: spool D if found desirable. This brake would be carried on a pivoted arm actuated
by a forked or other lever by which it would be thrown into contact with the
spool between the spool and the steel guide plate E when the detector mechanism
throws the drum out of contact with the spool.
A point of great importance is the form, or shape of steel guide, being made
doubled over on the edge it presents a round surface to the yarn and at the same
time is made considerably stiffer, and thereby acting more quickly in stopping
the spool when the stop motion operates.
The detector mechanism to throw the drum A out of contact with the spool D
when the yarn breaks is operated by the rotating wiper L which comes into contact
with the end of the detector guide or wire G when it is allowed to fall. The
movement of the connecting rod M raises or draws back the stop catch m releasing
the support a of the pivoted standards A' in bearings a¹ in which the axle of the
drum A is supported and allows the winding drum A to fall back out of contact
with the spool D and against the brake N by which it is stopped.
The essential features of the invention are
1st. The arranging of the spool carrying lever B and the steel guide plate E
or its equivalent so that the spool may be wound below the drum and the thread
carried up from the detector guide or mechanism G over a top guide roller H
and passed down through the drum. A to the spool 1 to give sufficient length of
yarn to prevent ends being wound onto the spool and at the same time not so
much as will over weigh the detector wire G and prevent it acting on the breaking
of a thread.
2nd. The arranging of the steel guide plate E or its equivalent and the spool
carrying lever B in such a manner that the relative position of the periphery of
the spool D to the steel guide plate as it fills or increases in size shall remain
the same so that the point of winding will not alter in any appreciable or
detrimental manner.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what we
we claim is:-
1. A split drum winding machine having the several parts constructed and
arranged substantially as and for the purpose described.
2. The improvements in split drum winding frame substantially as described
and shown.
