Improvements in Machines for Winding Yarn onto Spools or
Bobbins.
We, SAMUEL HERBERT BROOKS, Machine Maker, RICHARD ALEXANDER
DOXEY, Machine Maker, and JOHN SAMUEL BROOKS, Sub-Manager, all of the
Union Ironworks, West Gorton, in the County of Lancaster, do hereby declare the
nature of this invention to be as follows:--
This invention relates to that class of machine known as drum-winders in
which motion is imparted to a spool or bobbin by surface contact with a drum or
intermediate carrier upon which the spool or bobbin is held in position by a guide
or carrier.
The object of our invention is to cause the winding of the yarn upon the spool or
bobbin to cease when the same has reached a required diameter.
It consists essentially of a winding frame provided with a pivoted tumbling or
knocking off lever which when the spool or bobbin is wound to the required
diameter is released and lifts the full spool or bobbin out of contact with the drum
or otherwise causes the operation of winding to cease.
In carrying out the invention we pivot at or near the side of the guide or
carrier a tumbling bracket or lever which is sustained in position by the carrier
whilst the winding is proceeding. The pivoted lever is made sufficiently heavy or
has attached to it a weight or spring for the purpose of raising the carrier or spool
out of contact with the drum when the said pivoted lever is released.
When the carrier or spool is lifted above a certain height it is raised clear
of the pivoted lever, the said lever then falls forward or moves upon its pivot.
It is the movement of this lever when thus released that causes the cessation of the
winding.
This cessation of winding may be effected in several ways such as by raising the
spool or bobbin out of contact with the winding drum; by stopping the rotation
of the winding drum; by inserting a thin plate or strip of metal, cardboard, or the
like, between the drum and the spool or bobbin; by cutting or severing the thread,
or by other similar means.
At present we prefer to accomplish our object by raising the spool or, bobbin
out of contact with the drum and for this purpose we construct the pivoted lever
with a projecting piece or bracket, which when the lever falls or is tilted over the
said projecting piece comes in contact with the under side of the carrier and raises
it up so that the spool or bobbin is clear of the drum.
Instead of raising the bobbin out of contact with the drum, the drum may be
stopped by the lever falling and coming in contact with a ratchet wheel or pro-
jection on the drum or its spindle, or by releasing a pawl which would engage
therewith or by a brake on the drum or its spindle which would be thrown into
action by the falling of the lever.
Another modification of the invention is to insert between the drum and the
spool or bobbin a thin card or piece of metal by the falling of the lever. The
card would be carried by or acted upon by the falling lever and when
inserted between the two would prevent contact or so stop the rotation of the
spool or bobbin.
Another modification is to attach to the pivoted lever a blade or other apparatus
which would on the falling of the lever be brought into contact with the thread and
thus cut or break it causing the winding to cease.
It will be evident that the falling or movement of the pivoted lever may be made
to operate other devices for stopping the winding.

page_text: The pivoted lever is fitted with an adjustable plate or bracket preferably of
hardened steel which can be adjusted to any position so as to provide for knocking
off at any required diameter of spool or bobbin. The carrier is also fitted with a
similar plate or bracket against which the plate on the pivoted lever or bracket
rests. These two plates bear one against the other and as the carrier or spool 5
slowly rises as the winding proceeds-the plate thereon moves or slides upon the
plate on the pivoted lever until it is raised above it when the lever falls and causes
the cessation of the winding by one of the operations already described.
it
The pivoted lever or bracket may also be fitted with a handle so that by turning
upon its pivot in an opposite direction it may also be used to lift and hold the 1
carrier and spool or bobbin clear of the drum for doffing or other purposes.

Improvements in Machines for Winding Yarn onto Spools or
Bobbins.
We, SAMUEL HERBERT BROOкs, Machine Maker, RICHARD ALEXANDER
DOXEY, Machine Maker, and JOHN SAMUEL BROOKS, Sub-Manager, all of the
Union Ironworks, West Gorton, 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:-
This invention relates to that class of machine known as drum-winders in which
motion is imparted to a spool or bobbin by surface contact with a drum or inter-
mediate carrier upon which the spool or bobbin is held in position by a swinging
guide arm or carrier.
The object of our invention is to cause the winding of the yarn upon the spool or
bobbin to cease when the same has reached a required diameter.
It consists essentially of a winding frame provided with a pivoted tumbling or
knocking off lever which when the spool or bobbin is wound to the required
diameter is released and lifts the full spool or bobbin out of contact with the drum
or otherwise causes the operation of winding to cease.
It will be fully described with reference to the accompanying drawings in each
of which sufficient of the machine is shown to illustrate the invention as applied
thereto.
Fig. 1. Side elevation of winding drum with one form of the invention applied
thereto.
Figs. 2 to 6. Similar elevations showing modified forms of the invention.
The winding drum A, the stand B, the beam C, the swinging guide arms or
bobbin carriers D, and the other parts of the machine not shown in the drawings
are constructed of any ordinary form.
At or near the side of the swinging arm or bobbin carrier D we pivot a tumbling
bracket or lever E which is maintained in position whilst the winding proceeds by
resting or bearing against the bobbin carrier D. The lever E is fitted with an
adjustable plate or bracket e secured thereto by a set screw, bolt or other convenient
means. The plate or bracket e preferably of hardened steel is attached so that it
can be adjusted to any position so as to provide for knocking off at any required
diameter of spool or bobbin. The bobbin carrier D is also fitted with a similar
plate or bracket d against the edge of which the face of the plate e on the pivoted
lever or bracket E rests. The bobbin carrier D is slowly raised as the winding
proceeds and the diameter of the bobbin increases, this movement causes the plate d
thereon to move or slide up the face of the plate e on the pivoted lever E until it
is raised above its edge whereupon the lever E is released and falls causing the
cessation of the winding.

page_text: This cessation of winding may be effected in several ways such as by raising the
spool or bobbin out of contact with the winding drum; by stopping the rotation of
the winding drum; by inserting a thin plate or strip of metal, cardboard, or the
like, between the drum and the spool or bobbin; by cutting or severing the thread;
or by other similar means.
Referring to Fig. 1, the pivoted lever E is provided with a projecting tail piece
or bracket F which when the lever is released and falls comes in contact with the
underside of the bobbin carrier D and raises it up raising the spool or bobbin out
of contact with the drum A. The lever E is also provided with a brake block G
which by the same movement is brought into contact with the face of the drum and
its rotation stopped. The lever is drawn down by the spring It is evident that
either the lifting bracket F or the brake G may be utilized separately or
independently of the other.
Referring to Fig. 2, the rotation of the winding drum A is stopped upon the
falling of the lever E by it coming into contact with ratchet teeth or projections a
upon the side of the drum or its spindle. The lever E is provided with a projecting
finger H and upon the spindle or upon the side of the winding drum is fitted a
wheel carrying the teeth or projections a Instead of the lever E coming directly
into contact with the teeth a on falling it may release a pawl or catch which will
engage therewith.
In some cases the continuous running of the driving band I after the rotation of
the winding drum A has been stopped is considered objectionable.
Referring to Fig. 3, to the pivoted lever E is attached a bracket K carrying a
pulley k over which the driving band I passes. When the lever is released the end
to which the bracket K is attached falls and the tension of the band rendered so
slack that it ceases to drive the drum A. The lever is provided with a bracket k¹
to prevent it falling too low and is also made in two parts or divided on its pivot
so that the front end can be raised without moving the back end and by raising
the front part by the handle e the bobbin carrier D will at the same time be
lifted.
Referring to Fig. 4, in addition to the bracket K with pulley k for reducing the
tension of the driving band I the lever E is fitted with a brake G¹ carried on an
arm or bracket g¹. The brake G¹ when the lever falls comes in contact with the
side of the winding drum A or with the face of a wheel or pulley on the spindle.
The brake G' may be used without the tension pulley k.
Referring to Fig. 5, in addition to the bracket K with tension pulley k the lever
is fitted with a blade or knife L which on the falling of the lever comes in contact
with the bar M and cuts the thread as the yarn from the cop passes between the
knife and the bar to the drum. The blade or knife L may be used without the
tension pulley k.
Referring to Fig. 6, in which another modification of the invention is shown a
thin strip of card or piece of metal N is attached to the lever E which on the
falling of the lever is inserted between the surface of the winding drum A and the
spool or bobbin thereby preventing contact between the surfaces of the drum and
spool and so stopping the rotation of the latter. It will be evident that the falling
or movement of the pivoted lever may be made to operate other devices for
stopping the winding.
The pivoted lever E is also in each case preferably fitted with a handle e" by
which it can be operated or lifted by hand at any time to stop the winding, and a
small stop washer b may be placed on the stud on which the lever E is pivoted to
prevent it falling too low.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. A drum winding frame provided with a pivoted tumbling or knocking off lever
working in conjunction with the swinging guide arm or bobbin carrier which is

page_text: released when the bobbin or spool is wound to the required diameter causing a
cessation of the winding substantially as described.
2. A winding frame constructed with an adjustable plate or bracket on the
swinging guide arm or bobbin carrier and a similar adjustable plate or bracket on
a pivoted lever sliding across the other as the carrier rises whereby the pivoted
lever is released when the spool or bobbin has acquired the required diameter to
cause a cessation of the winding substantially as described.
3. In a drum winding machine the arrangement and combination of mechanism
for causing the cessation of winding when the bobbin or spool is wound to the
required diameter substantially as described and shown with reference to either of
the Figs. 1 to 6 of the drawings.
