PROVISIONAL SPECIFICATION.
Improvements in or relating to Feeding Noble Combing Machines or
the like.
I, TAYLOR BURROWS, of 88, Upper Kennington Lane, London, Engineer, do
hereby declare the nature of this invention to be as follows:-
-
This invention has for its object improvements in or relating to feeding Noble
combing machines or the like.
In the "ball” as prepared and used in the present feed it is turned positively
by friction. rollers on which it rests and furthermore, the fibre is usually wound
loose on said ball.
i
This for vegetable fibres is not advantageous as the slivers have a tendency to
either break or become too slack and fall off the sides and this leads to much waste
and inconvenience. In the can feed hitherto used or tried it is found difficult it
not impossible to get sufficient weight in the cans which have been made in 4 com-
partments and as one sliver finished before the others several yards have to be
wasted at the end of almost every can.
To obviate these grave inconveniences and to obtain other improvements and
advantages I propose to feed by heavily compressed balls with one, two or four
slivers (or other suitable number) on each ball and the sliver is pulled off the ball
as required and this keeps all the slivers at an even tension.
I effect this by winding on to a ball under very heavy pressure the number of
alivers it is desired each ball to have: This heavy pressure causes the slivers to
detach themselves freely from the underlying layers.
The following is a suitable arrangement for effecting this winding:
I use a deep-sided reel or bobbin through which I insert a spindle or axis by
which said bobbin is turned this spindle (which extends some distance each side
of and beyond the bobbin) being held or guided in slotted guides or bearings and
being heavily weighted or controlled by suitable springs or levers said reel or
bobbin may be otherwise suitably arranged and adapted to be pressed firmly against
an idle roller carried in fixed or other suitable bearings or supports this idle
roller being of a a width adapted to fit in between the side cheeks or discs
forming the deep sides of the reel or hobbin.
I now, lead on four or other suitable number of slivers which are led parallel
on to said bobbin and the latter is then forcibly rotated and as the fibres (slivers)
ape lapped or wound on the said reel or bobbin they are firmly pressed onto the
said bobbin thereby giving the dual advantages of (1) getting more material on
each bobbin and (2) so winding the fibre (especially China grass), that it will run
off or unwind very much better. I cause the axis of this metallic bobbin on which
the silvers are lapped to rest at each end when on the combing machine in
a V-shaped or approximately V-shaped stand or support so that the weight of the
bobbin at its full charge being heavy presses the ends down in the V-shaped holder
or support but as the slivers are pulling on a big diameter the bobbin is easier
to move so that in the feeding motion or feeding operation the pull of the slivers
causes the bobbins to revolve to the extent of the sliver required by the feed.
This V-shaped holder in which the ends rest prevents the over-running of the
bobbin and is the principal claim I make in this system of feeding.

page_text: For instance these V-shaped or converging bearings may be formed arrange!
or mounted on short stays or supports bolted screwed or otherwise suitably fixed
to and carried on or by the Noble comb or the like combing machine.
A further improvement or modification consists in providing the perforated
feed plate with lips, nozzles or projections (advantageously bell-mouthed with
rounded edges thereto) to each alternate aperture through said feed plate.

Improvements in or relating to Feeding Noble Combing Machines'or
the like.
I, TAYLOR BURROWS, of 88, Upper Kennington Lane, London, Engineer, 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 has for its object improvements in or relating to feeding Noble
combing machines or the like.
In the "ball" as prepared and used in the present feed it is turned by friction
rollers on which it rests and furthermore the fibre is usually wound loose on
said ball.
This for vegetable fibres is not advantageous as the slivers have a tendency to
either break or become too slack and fall off the sides and this leads to much waste
and inconvenience. In the can feed hitherto used or tried it is found difficult if
not impossible to get sufficient weight in the cans which have been made in 4 com-
partments and as one sliver finished before the others several yards have to be
wasted at the end of almost every can.
To obviate these inconveniences and to obtain other improvements and
advantages I propose to feed by heavily compressed balls with one, two or four
slivers (or other suitable number) on each ball and the sliver is pulled off the ball
as required and this keeps all the slivers at an even tension.
I effect this by winding on to a ball under very heavy pressure the number of
slivers it is desired each ball to have. This heavy pressure causes the slivers to
detach themselves freely from the underlying layers.
The following is a suitable arrangement for effecting this winding :-
I use a deep-sided reel or bobbin through which I insert a spindle or axis by
which said bobbin is turned this spindle (which extends some distance each side
of and beyond the bobbin) being held or guided in slotted guides or bearings and
being heavily weighted or controlled by suitable springs or levers or said reel or
bobbin may be otherwise suitably arranged and adapted to be pressed firmly against
an idle roller carried in fixed or other suitable bearings or supports this idle
roller being of a width adapted to fit in between the side cheeks or discs
forming the deep sides of the reel or bobbin.
I now lead on four or other suitable number of slivers which are led parallel
on to said bobbin and the latter is then forcibly rotated and as the fibres (slivers)
are lapped or wound on the said reel ar bobbin they are firmly pressed onto the
said bobbin thereby giving the dual advantage of (1) getting more material on each
bobbin and (2) so winding the fibre that it will run off or unwind very much
better.
The bobbin on which the slivers are lapped either in the aforesaid or other

page_text: suitable manner is provided either with a spindle or axle right through same and .
extending each side or with gudgeons or trunnions or other suitable axis on which
said bobbin is fixed and which consequently will revolve with said bobbin and
said axle ends or gudgeons rest when on the combing machine in V-shaped or
approximately V-shaped bearings or supports so that the weight of the bobbin
being heavy presses the axle ends or gudgeons down in the V-shaped holders or
supports but as the slivers are pulling on a big diameter the bobbin is easy to move
so that in the feeding motion or feeding operation the pull of the slivers tends to
raise the bobbin or ease same in its bearings and allow the bobbins to revolve to
the extent of the sliver required by the feed. These V-shaped holders or bearings
in which the bobbin is supported prevent the over-running of the bobbin.
For instance these V-shaped or converging bearings may be formed arranged
or mounted on short stays or supports bolted screwed or otherwise suitably fixed
to and carried on or by the Noble comb or the like circular combing machine.
Referring to the accompanying drawings-Fig. 1 is a local plan view of a bobbin
resting in these V-shaped supports or bearings.
Fig. 2 is a view in elevation (partly in section) on the line 2-2 Fig. 1.
a is the reel or bobbin and 6b the ends of the spindle or axle fixed therein
or bb may be gudgeons or trunnions fixed to said bobbin.
cc are the V-shaped holders or bearings (in which said ends bb rest). formed
arranged or mounted in or on the supporting arms d fixed to the circular revolving
ring or frame e of the machine.
fis the feed plate through which the feed passes.
It will thus be obvious that when the slivers are pulled through the feed
plate the tendency will be to caso the ends. b.in their bearings c while on the
other hand the ends b will by the weight of the bobbin and slivers thereon be
wedged between the converging sides of the V-shaped bearing and consequently
the latter will so bind or hold the bobbin as to prevent over-running of the latter.
It will be seen that by this arrangement I secure an automatic adjustment by the
force tending to restrain the rotation of the ball. When the ball is full and
consequently heavy it bears with proportionately greater force upon the V-shaped
bearing than when the ball is nearly exhausted. But in the former case the pull
of the sliver comes upon a larger diameter than in the latter case and the conse-
quence is that at all the successive stages of the unwinding the tension upon the
sliver remains approximately constant.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
In Noble or the like circular combing machines-the combination therewith.
of V-shaped bearings such as cc in which are supported the bobbins or reels of
fibre to be combed the said V-shaped bearings being arranged and operating in
conjunction with the bobbins substantially in the manner and for the purposes
hereinbefore described. ·
