Improvements in Carding Engines.
We GEORGE ASHWORTH and ELIJAH ASHWORTH of the firm of Ashworth Brothers
of the Moss Brook Works Collyhurst Manchester in the County of Lancaster
Engineers do hereby declare the nature of this Invention to be as follows:-
:-
Our Invention has for its object to produce slow motions of the main carding
cylinder of a carding engine suitable to the operations of stripping and of grinding.
During the operation of stripping the main cylinder we have found it to be
advantageous that the said cylinder shall revolve very slowly and to obtain an
exceedingly slow motion is one of the objects of our invention. We obtain the said
motion from the side shaft which gives motion to the feed rollers. We provide
the said shaft with a worm and we fix a worm wheel upon the main cylinder shaft or
we cut or form upon a pulley or part which is fixed upon such shaft, teeth, notches or
projections with which the said worin can engage. We arrange for the said worm to
slide into and out of gear or to be brought into gear by the ordinary sidewise move-
ment of the said shaft after being slid some distance thereon, or otherwise to be
caused to actuate the wheel or pulley upon the main cylinder shaft at the required
times, the lap having been moved back from between the feed rollers. We may
apply a special worm shaft instead of using the said side shaft. We also obtain
a slow movement of the main cylinder by connecting a pitch chain wheel upon the
shaft of the said cylinder with a pinion upon the feed roller or the doffer shaft,
the connecting chain being removable. The doffer may receive motion in a suitable
manner as for example the doffer may be driven by the parts used previously to the
date of our present invention for actuating the doffer during the grinding of the main
cylinder but we prefer to actuate the said doffer when stripping or grinding by
the means hereinafter described. A grooved band pulley forming part of the

page_text: loose pulley which is mounted upon one end of the main cylinder shaft or is caused to
revolve with such pulley is arranged to be connected by means of a band with a
pulley which may be formed in one piece with or be mounted to revolve with the strap
pulley whereby the doffer is actuated during the ordinary working of the engine.
We also provide the said strap pulley with a band pulley for driving the stripping
brush when required. An important advantage arising from this method of changing
the actuation of the doffer is that the principal parts of the mechanism are always in
position upon the carding engine so that it is only necessary to make the required
changes in the connecting belts or bands as for example the only necessary change
may be to remove a belt in one place and to apply a band in another.

Improvements in Carding Engines.
We GEORGE ASHWORTH and ELIJAH ASHWORTH of the firm of Ashworth Brothers
of the Moss Brook Works Collyhurst, Manchester in the County of Lancaster
Engineers 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 and accompanying drawings.
Our invention has for its object to produce slow motions of the main carding
cylinder of the carding engine suitable to the operations of stripping and of grinding.
During the operation of stripping the main cylinder we have found it to be
advantageous that the said cylinder shall revolve very slowly and to obtain an
exceedingly slow motion is one of the objects of our invention. We obtain the said
motion from the side shaft which gives motion to the feed rollers. We provide
the said shaft with a worm and we fix a worm wheel upon the main cylinder shaft or
we cut or form upon a pulley or part which is fixed upon such shaft, teeth, notches or
projections with which the said worm can engage. We may apply a special worm
shaft instead of using the said side shaft. In a modification we obtain a slow
movement of the main cylinder by connecting a pitch chain wheel upon the shaft of
the said cylinder with a pinion upon the feed roller or the doffer shaft, the connecting
chain being removable. The doffer may receive motion in a suitable manner as
for example the doffer may be driven by the parts used previously to the date of our
present invention for actuating the doffer during the grinding of the main cylinder

page_text: but we prefer to actuate the said doffer when stripping or grinding by the means
described as follows. A grooved band pulley forming part of the loose pulley which
is mounted upon one end of the main cylinder shaft or is caused to revolve with such
pulley is arranged to be connected by means of a band with a pulley which may
be formed in one piece with or be mounted to revolve with the strap pulley whereby
the doffer is actuated during the ordinary working of the engine. We also provide
the said strap pulley with a band pulley for driving the stripping brush when
required.
Our invention will be best understood when described with reference to the
accompanying drawings wherein Fig. 1 represents a side Elevation of so much of
a carding engine as is necessary to the illustration of our invention. Fig. 2 is a plan
of the parts upon the same side of the Engine. Figs. 3 and 4 are corresponding
views of parts upon the other side of the Engine and Figs. 5 and are illustrative of
modifications in the arrangements. In Figs. 1 and 2 a is the loose pulley being the
ordinary fast pulley whereby the cylinder is revolved when the engine is at work.
The pulley a is the ordinary loose pulley with the exception that it is formed with a
groove to receive a band c which drives a pulley d which is attached to the ordinary
pulley and as a consequence is connected with the ordinary pinion e. The said
pinion gears with the ordinary wheel which is fixed upon the doffer shaft. A second
pulley is formed in one piece with the pulley d or is attached to it and this
second pulley drives the stripping brush in the indicated direction by means of
a band h. During the ordinary working of the engine the doffer is actuated by means
of a belt which drives the pulley i which is a part of the ordinary arrangement, and is
fixed to the said pinion e. When the main cylinder is to be stripped the said belt is
removed from the pulley i whereby the doffers receives motion during the ordinary
working of the engine as aforesaid and the band c is applied to connect the pulley d
with the loose pulley a in the manner represented in Figs. 1 and 2. When the
ordinary driving belt which drives the main cylinder is shifted on to the loose pulley a
the doffer will be revolved and the said belt will cease to drive the main cylinder
directly. An important advantage arising from this method of changing the actuation
of the doffer is that the principal parts of the mechanism are always in position upon
the carding engine so that it is only necessary to make the required changes in
the connecting belts or bands. On the other side of the engine represented in
Figs. 3 and 4 the doffer shaft imparts motion to the side shaft by means of the bevel
wheels as is usual. This shaft is the ordinary shaft, which transmits motion to
the shaft s which actuates the feed rollers. Upon the main cylinder shaft we
fix a worm wheel m. In practice we form the ordinary belt pulley n with teeth
or projections with which a worm o can engage a special extra wheel being thereby
dispensed with but if preferred a wheel m may be attached to the ordinary pulley n or
to its shaft. The worm o is mounted upon the side shaft which actuates the
feed rollers as aforesaid. This shaft is mounted in its bearing brackets p. p² so that it
can be swivelled horizontally in order to withdraw the bevel pinion from gear with
the wheel when the feed rollers are to be stopped this being the ordinary
arrangement. This horizontal movement of the shaft also withdraws the worm from
with the worm wheel m. When so withdrawn the worm can be slid upon
gear
the side shaft entirely away from the wheel m and be kept out of the way near
the bearing p during the ordinary working of the engine. Preparatory to the
stripping operation we either remove the pinion from the shaft so as to stop
the revolution of the feed rollers or we withdraw the lap from between the rollers so
as to stop the feed so that the rollers may continue to revolve without feeding cotton
to the licker in t. The worm o is then slid along the shaft until it is in its working
position as represented in Figs. 3 and 4. When in this position the worm is upon
a fast key and bears against a shoulder the action of the worm tending to keep
it against this shoulder. The side shaft being shifted back to its working position the
worn will gear with the wheel o and all the parts will then be in order for the
stripping. The driving belt being shifted on to the loose pulley a the main cylinder

will cease to revolve at its working speed but will receive a slow motion through the
band pulley d pinion e wheel f doffer shaft bevel gearing 11 side shaft and
the worm and wheel o m. In the modification illustrated by Fig. 6 a special worm
shaft is employed to drive the main cylinder in place of the ordinary side shaft k.
This shaft receives motion from the doffer shaft by means of a worm and wheel and
gives motion to the cylinder shaft by means of a worm and wheel as in the caso of the
arrangement shown in Figs. 3 and 4. In Fig. 5 a pitch chain w is used to drive
the main cylinder. The flange of the ordinary pulley is cut or formed with teeth with
which the chain engages. A small pinion upon the doffer shaft or upon the feed
roller shaft imparts motion to the chain. The said chain is only applied when
the slow motion is required. The motion of the main cylinder will not be quite
so slow as when the worm and wheel motion is used and we prefer to use the
latter. We do not confine ourselves to the method of driving the stripping brush
by means of the grooved pulley g and the band h.
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 claim is :-
(1) In a carding engine the worm o upon the side, shaft k arranged to be
moved into gear with the worm wheel m in combination with arrangements for
driving the doffer when the driving belt is shifted to the loose pulley substantially as
and for the purpose set forth and indicated.
