IMPROVEMENTS IN MACHINERY FOR PREPARING WOOL OR OTHER FIBRES FOR SPINNING to be as follows
Year: 1885

page_text: I JOHN CLAYTON MEWBURN of 169 Fleet Street, in the City of London, Fellow
of the Institute of Patent Agents do hereby declare the nature of my invention
for "IMPROVEMENTS IN MACHINERY FOR PREPARING WOOL OR OTHER FIBRES FOR
SPINNING to be as follows:-
"
The object of this invention is to produce regular and mathematical work in the
formation of the thread from the sliver and for this purpose the movements for
effecting the feeds and exits of the fibres into and from the preparing machines are
rendered uniform and synchronous with each other and quite independent of the
other parts of the machine which is not the case in machines as at present
arranged.
This is effected as follows:-On the shaft of the drum of one of the machines,
say the third carding or finishing machine, is keyed a driving pulley which drives
by means of a belt another pulley of the same diameter. This pulley is keyed on
a shaft which is supported. in bearings and, extends to the second carding or
preparing machine. This same shaft carries another pulley which by a belt drives
a pulley on the shaft of a pinion in gear with a toothed wheel on the shaft of the
doffing cylinder. The doffing cylinder by rods and bevel gearing transmits the
motion to the feed table.
The shaft which as above described extends to the second carding or preparing
machine carries in this machine a pulley which by a belt drives a pulley on whose
shaft is a pinion; this pinion is in gear with a toothed wheel on the shaft of the
doffing cylinder of this machine. This doffing cylinder as in the other machine
transmits the motion to the feed table.
It will readily be seen that by this arrangement the shaft which controls the
feed and exit of the fibre in the third carding or finishing machine through
the intermediation of the doffing cylinder, likewise communicates its motion
in the second carding or preparing machine to control the feed and exit of the
Prine 221

page_text: fibre by the like arrangements. These two movements being subordinate to each
other and synchronous are quite independent of the movements of the drum of
the second carding or preparing machine, that is to say that the movements for
effecting the feed and exit of the fibre are proportionate to the speed of the
drum of the machine that actuates them. The machine which controls them
need not be the third carding or finishing machine as described but may be any
one of a series of two or more machines to all of which the connecting shaft above
described may extend.
It will also be understood that as the drums are independent if the third carding
or finishing machine were stopped the drum of the other machine (or machines)
can continue its movement although the feed and exit of the fibre are interrupted
by the stoppage of the third carding or finishing machine. The workers must be
controlled or driven directly from the doffing cylinder. Instead of a shaft for
transmitting the motions between the machines a belt or other contrivance may be
employed. The object to be gained is to effect the feeds and exits of the fibre
always at a proportionate speed and to control them from a single machine. The
invention is applicable to all machines for preparing wool or other fibres for
spinning..

Improvements in Machinery for Preparing Wool or other
Fibres for Spinning.
I JOHN CLAYTON MEWBURN, of 169 Fleet Street, in the City of London, Fellow
of the Institute of Patent Agents 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:-
The object of this invention is to produce regular and mathematical work in the
formation of the thread from the sliver and for this purpose the movements for
effecting the feeds and exits of the fibres into and from the preparing machines are
rendered uniform and synchronous with each other and quite independent of the
other parts of the machine which is not the case in machines as at present
arranged.
The manner in which this is effected will be understood by the annexed
drawings of machinery in which the invention is embodied. Figure 1 is a side
view of a second carding or preparing machine, Figure 2 a side view of the third
carding or finishing machine, and Figure 3 a plan of the two machines:-On the
shaft of the drum A of the third carding or finishing machine is keyed a pulley B
which drives by means of a belt another pulley C of the same diameter. This
pulley is keyed on a shaft D which is supported in bearings and extends to the
second carding or preparing machine. This same shaft D carries another pulley E
which by a belt drives a pulley F on the shaft of a pinion G in gear with a toothed
wheel H on the shaft of the doffing cylinder X. The doffing cylinder by suitable
intermediate parts such as rods and bevel gearing I, 1 transmits the motion to the
feed table.
The shaft D which as above described extends to the second carding or preparing
machine carries in this machine a pulley E¹ which by a belt drives a pulley F¹ on
whose shaft is a pinion G¹; this pinion is in gear with a toothed wheel H¹ on the
shaft of the doffing cylinder X³ of this machine. This doffing cylinder as in the
other machine transmits the motion to the feed table.
It will readily be seen that by this arrangement the shaft D which controls
the feed and exit of the fibre in the third carding or finishing machine through
the intermediation of the doffing cylinder, likewise communicates its motion in the
second carding or preparing machine to control the feed and exit of the fibre by
the like arrangements. These two movements being subordinate to each other and
synchronous are quite independent of the movements of the drum A¹ of the second
carding or preparing machine, that is to say, that the movements for effecting the
feed and exit of the fibre are proportionate to the speed of the drum of the machine
that actuates them. The machine which actuates and controls them need not be
the third carding or finishing machine as described but may be any one of a series
of two or more machines to all of which the connecting shaft D may extend.
It will also be understood that, as the drums are independent, if the third carding
or finishing machine were stopped the drum of the other machine (or machines)
can continue its movement although the feed and exit of the fibre would be

page_text: interrupted by the stoppage of the third carding or finishing machine. The
workers must be controlled or driven directly from the doffing cylinder. Instead
of the shaft D for transmitting the motions between the machines a belt or other
contrivance may be employed. The object to be gained is to effect the feeds and
exits of the fibre always at a proportionate speed and to control them from a single
machine. The invention is applicable to all machines for preparing wool or other
fibres for spinning.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, as communicated to
me, I declare that what I claim is
Constructing machinery for preparing wool or other fibres for spinning in such
manner that the movements for effecting the feeds and exits of the fibres are
uniform and synchronous with each other and independent of the other parts of
the machine, substantially as hereinbefore described and represented in the
annexed drawings.
