Improvements in Split Drum Machines for Winding Cotton and other
Yarns or Threads.
I, JOHN BOYD, of Shettleston Iron Works, Glasgow, Engineer, do hereby
declare the nature of this invention to be as follows:-
This invention comprises improvements in "split drum machines" for wind-
ing cotton and other yarns or threads.
In carrying out my invention for winding single yarn each split drum has a
central sleeve piece made to run loosely on a longitudinal driven shaft and
instead of each drum (or the two contiguous parts of it which go to form each
split drum) being fixed rigidly to a spindle carried at both ends in bearances
of some kind and each as usual being driven separately by a band or belt from
a central shaft a number of split drums made with central sleeves are carried
on the one longitudinal driven shaft referred to. The split drum is by pre-
ference driven by frictional contact with its shaft so that it may be easily stopped
by the hand or otherwise while the shaft is running.
By one modification this is accomplished in a simple and effective manner
by two blocks of wood being let into two opposite grooves formed in a pro-
longed part of the central tubular sleeve and pressed together by two opposite
screws of a crescent shaped, cast iron or steel, glandpiece causing the blocks to
grip the running shaft with sufficient power to drive the split drum. The
two-armed holder for holding the spindle or spool on to which the yarn is wound
is carried jointed to and supported in its lowest as well as in its raised position
by a longitudinal rail bracket similar to what is shewn in Patent No. 5811 of
1886, Figure 11, Sheet 3, which is by preference placed so that the yarn is
taken upwards through the split drum and so that the winding may take place
on the top of latter. On the same longitudinal rail bracket and pivoted on the
same spindle is an adjustable swinging bracket to which is fixed the usual guide
plate also made adjustable which in its working position should be set as close
as possible to the drum and to the surface of the yarn on the spool which is being
wound without touching either. For this purpose the swinging bracket is adjust-
ably secured to its longitudinal rail bracket by means of a set screw by which
it is set closer or farther away from latter against the resistance of a spiral
spring placed between the swinging bracket and the longitudinal rail bracket.
To one side of the split drum (preferably at its left side) and fixed to or form-
ing part of the swinging bracket is a horizontal hand lever which when pressed
downwards against the resistance of the spiral spring causes the guide plate
or some other part of the swinging bracket to act as a hand brake to brake and stop
the frictionally driven split drum which is necessary in the process of starting
winding so as to get the yarn which is to be wound into the diagonal slot of
the drum. The guide plate so that it may act also as a brake without injuring
the split drum may be made of vulcanite or some other anti-friction substance
or some such substance may be fixed on the under side of a metal plate to serve
the same purpose. Instead of the plate being fixed to a swinging bracket it

page_text: may be fixed in its proper position rigidly to a projection of the longitudinal
rail bracket and instead of a hand brake lever being used to stop the split drum
it may be done by the hand of the worker and the brake lever dispensed with.
In a modification in which automatic stop motion mechanism is used in com-
bination with my improved split drum mechanism for winding two or more ends
on to one spool I prefer to use a stop motion detector mechanism similar to
what is described and shewn in Figures 2 and 3, Sheet 2 of Patent No. 5811
of 1886 already referred to in which a fulcrumed catch lever having a front
projecting setting-on arm is supported at its front weighted end by a catch of
a swinging detector holder which when the latter is released by the action of a
cam on a fallen detector allows the weighted end of the lever to drop and by
the further action of its catching parts swings all its detectors out of the way
of the cam and at the same time causes an inner end of the lever to rise. Å
lateral projecting part of the inner end of the catch lever is connected by an
adjustable connecting rod to an under and lateral projecting part of the swing-
ing plate bracket referred to in the former modification so that when any one
of the various strands being wound together breaks or fails and this connecting
rod is raised it will cause the plate of the swinging bracket at once to lift the
spool (which is being wound) away from the driving surface of the split drum
which instantly stops the winding and at the same time stops and brakes the
spool. When the broken end or ends are pieced and the spool is lowered so
as to rest it on the lifted plate of the swinging bracket, by lifting the setting-on
handle so that its catching part is raised as far as it will go beyond the catch
of the detector holder the connecting rod is made to lower the spool on to the
drum and at the same time cause the plate of the swinging bracket to brake
and stop the split drum so that the strands to be wound may be passed into the
diagonal slot. Thereafter by lowering the setting-on handle till its catch engages
with the catch of the detector holder the brake plate of the swinging lever ceas-
ing to hold the split drum and assuming its working position (clear of the drum)
the winding process is resumed. When the setting-on handle is being used to
stop the split drum its front part has a projection so shaped to act on the
detector holder as to keep its detectors clear of the running cam.
Conical as well as parallel split drums may be used to advantage in combina-
tion with my improved mechanism for driving, starting and stopping such
drums.
Improvements in Split Drum Machines for Winding Cotton and other
Yarns or Threads.
I, JOHN BOYD, of Shettleston Iron Works, Glasgow, Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:—
This invention comprises improvements in "split drum machines" for wind-
ing cotton and other yarns or threads.
In order more fully to describe my improvements and to shew how they can
be carried into effect I will describe their application as shown in the accom-
panying sheet of drawings.
Figure 1 is a front vertical section of as much of a split drum machine as

page_text: is necessary to illustrate two modifications of my invention. Figures 2 to 11
are separate views of some details of Figure 1.
In these drawings the same reference numerals are used to mark the same or
like parts wherever they are repeated.
In carrying out my invention for winding single yarn, Figures 1 to 11, as
shewn in left side of Fig. 1, each split drum 12, Figs. 1, 2 and 3, has a central
sleeve piece 13 made to run loosely on a longitudinal driven shaft 14 and instead
of each drum 12 or the two contiguous parts of it, 15 and 16, which go to form
each split drum being fixed rigidly to a spindle carried at both ends in bear-
ances of some kind and instead of each complete split drum being driven as
usual separately by a band or belt from a central shaft the two contiguous
parts, 15 and 16, are fixed to the central sleeve piece 13 and a number of split
drums 12 made with central sleeves 13 are carried on the longitudinal driven
shaft 14 referred to. The split drum 12 is by preference driven by frictional
contact with its shaft 14 so that it may be easily stopped by the hand or other-
wise while the shaft is running.
By one modification this is accomplished in a simple and effective manner
by two blocks of wood 17 and 18 being let into two opposite grooves 19 and 20
formed in a prolonged part 21 of the central tubular sleeve and pressed together
on opposite sides of the shaft 14 by two opposite screws 22 and 23 of a crescent
shaped cast iron or steel gland piece 24, Figs. 4 and 5, causing the blocks 17
and 18 to grip the running shaft 14 with sufficient power to drive the split drum.
The two armed holders 25, Figs. 1 and 6, for holding the spindle or spool 26
on to which the yarn 27 is wound is carried jointed to and supported in its
lowest as well as its raised position by a longitudinal rail bracket 28 similar to
what is shown in Patent No. 5811 of 1886, Fig. 11, Sheet 3, which is by prefer-
ence placed so that the yarn 29 is taken upwards through the split drum 12
and so that the winding may take place on the top of latter. On the same
longitudinal rail bracket 28 and pivoted on the same spindle 30 is an adjust-
able swinging bracket 31, Figs. 1, 9, 10 and 11 to which is fixed the usual guide
plate 32 also made adjustable, which in its working position should be set as
close as possible to the drum 12 and to the surface of the yarn on the spool 27
which is being wound without touching either. For this purpose the swinging
bracket 31 is adjustably secured to its longitudinal rail bracket 28 by means of
a set screw 33 by which it is set closer or farther away from latter against the
resistance of a spiral spring 34 placed between the swinging bracket 31 and the
longitudinal rail bracket 28. To one side of the split drum 12 (preferably at
its left side) and fixed to or forming part of the swinging bracket 31 is a hori-
zontal hand lever 35 shown in dotted lines in Fig. 1 which when pressed down-
wards against the resistance of the spiral spring 34 causes the guide plate 32
or some other part of the swinging bracket 31 to act as a hand brake to brake
and stop the frictionally driven split drum 12 which is necessary in the process
of starting winding so as to get the yarn which is to be wound into the diagonal
slot of the drum. The guide plate 32 so that it may act also as a brake without
injuring the split drum may be made of vulcanite or some other anti-friction sub-
stance or some such substance may be fixed on the under side of a metal plate to
serve the same purpose. Instead of the plate being fixed to a swinging bracket it
may be fixed in its proper position rigidly to a projection of the longitudinal
rail bracket 28 and instead of a hand brake lever 35 being used to stop the split
drum it may be done by the hand of the worker and the brake lever dispensed
with.
In a modification shown on the right side of Fig. 1 in which automatic stop
motion mechanism is used in combination with my improved split drum mecha-
nism for winding two or more ends on to one spool I prefer to use stop motion
detector mechanism similar to what is described and shewn in Figures 2 and 3,
Sheet 2, of Patent No. 5811, of 1886 already referred to in which a fulcrumed

page_text: catch lever 36 having a front projecting setting-on arm 37 is supported at its
front weighted end by a catch 38 engaging with the catch 39 of a swinging
detector holder which when the latter is released by the action of a cam 40 on
a fallen detector allows the weighted end 37 of the lever to drop and by the
further action of its catching parts swings all its detectors out of the way of
the cam 40 and at the same time causes an inner end 41 of the lever to rise. A
lateral projecting part 42 of the inner end of the catch lever is connected by
an adjustable connecting rod 43 to an under and lateral projecting part 44 of
the swinging plate bracket 31 referred to in the former modification so that when
any end of the various strands 29 breaks or fails and this connecting rod 43 is
raised it will cause the plate 32 of the swinging bracket 31 at once to lift the
spool 27 which is being wound away from the driving surface of the split drum 12
which instantly stops the winding and at the same time stops and brakes the
spool, all as shown on the right hand side of Fig. 1. On the left hand side of
same figure the spool and the lifting plate being shown in position they occupy
when the strand 29 is unbroken and when the winding is going on. When the
broken end or ends 29 are pieced and the spool 27 is lowered so as to rest it
on the lifted plate 32 of the swinging bracket 31 by lifting the setting-on
handle 37 so that its catching part 38 is raised as far as it will go beyond the
catch 39 of the detector holder the connecting rod 43 is made to lower the
spool 27 on to the split drum and at the same time cause the plate 32 of the
swinging bracket 31 to brake and stop the split drum 12 so that the strands
to be wound may be passed into the diagonal slot. Thereafter by lowering the
setting-on handle 37 till its catch 38 engages with the catch 39 of the detector
holder the brake plate 32 of the swinging bracket 31 ceasing to hold the split
drum and assuming its working position (clear of the drum) the winding pro-
cess is resumed. When the setting-on handle 37 is being used to stop the split
drum its front part has a projection 45 so shaped to act on the detector holder
as to keep its detectors clear of the running cam 40.
Conical as well as parallel split drums may be used to advantage in combina-
tion with my improved mechanism for driving, stopping and starting such drums.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what
I claim is:-
In split drum winding machines;
1. The use of a central sleeve piece made to run loosely on a shaft, having
rigidly fixed to it the two contiguous parts which go to form each split drum,
each split drum so constructed being by preference driven by frictional contact
with its shaft.
2. The use of a central sleeve piece 13 made to run loosely on a shaft 14 having
rigidly fixed to it the two contiguous parts 15 and 16 which go to form each
split drum 12, and each split drum 12 so constructed being by preference driven
by frictional contact with its shaft substantially as hereinbefore described with
reference to Figures 1 to 5 of the accompanying drawings.
3. The use in combination of a two-armed spool holder a rail bracket and a
swinging bracket carrying a guide plate, which may also be used for the pur-
pose of stopping the split drum in machines made for winding single yarn.
4. The use in combination of a two-armed holder 25 a rail bracket 28 and a
swinging bracket 31 carrving a guide plate 32 which may also be used for the
purpose of stopping the split drum 12 in machines made for winding single yarn
substantially as herein before described with reference to Figure 1 and Figures 6
to 11 of the accompanying drawings.
5. The use in combination of a two-armed holder a rail bracket and a swinging
bracket carrying a guide plate which is also used for stopping the split drum
and also for lifting and stopping the spool which is being wound in combination
with stop motion detector mechanism."

the split drum 12, and also for lifting and stopping the spool which is being
wound in combination with stop motion detector mechanism substantially as
herein before described with reference to Figures 1 to 11 of the accompanying
