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 relates to the means for arresting the movements of certain parts
of the Carding Engine on the breakage of the sliver. Previously to our Invention
Carding Engines have been provided with motions which have stopped the revolution
of the doffer when the sliver has broken but we consider this method to be defective
for the reason principally that as the motion of the main cylinder continues after
the doffer has ceased to revolve the doffer becomes clogged or over-charged with
fibres at the point of contact with the main cylinder. To remedy this defect and
its attendant consequences we employ means for arresting the feed on the occurence
of a breakage of the sliver the revolution of the doffer continuing. We employ
levers which are sustained out of action by the intact sliver or by parts acted upon
by the sliver but are permitted to act when the sliver breaks and on such occurence
act upon parts which unlock or release one of the side shaft bearings so that it
can be moved to carry the bevel pinion out of gear and so stop the revolution of
the feed rollers. For this purpose we may use a modification of the stop motion
for which Letters Patent number 2252 of the year 1876 were granted to Joseph Dean
but for the purposes of our invention we employ part of such motion to act upon
other parts which release the side shaft bearing as aforesaid. We arrange for the
moving part of the clutch to act upon a detent lever which locks the said bearing
or upon a lever which is connected by means of a shaft or other suitable connection
with a detent or detent lever. We may employ a spring to move the said bearing
when released. We may modify the arrangement by connecting the detent with a
feeler lever which is situated in any convenient position so long as it can bear upon
or be acted upon by the sliver or we may apply such feeler lever or a pair of such
levers to the top or free pressing or calendering roller so that the dropping of such
roller on the breakage of the sliver effects the release of the said bearing.
Such levers or parts in connection therewith may bear either upward or downward
upon the roller journals or upon a part or upon parts moving with the roller as it
rises and falls.

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 relates to the means for arresting the movements of certain parts of
the Carding Engine on the breakage of the sliver such means being also adapted to
prevent overfilling of the can. Previously to our Invention Carding Engines have
been provided with motions which have stopped the revolution of the doffer when the
sliver has become broken but we consider this method to be defective for the reason
principally that as the motion of the main cylinder has continued after the doffer has
Die 83 7

page_text: ceased to revolve the doffer becomes clogged or over-charged with fibres at the point
of contact with the main cylinder. To remedy this defect and its attendant con-
sequences we employ means for arresting the feed on the occurrence of a breakage of
the sliver the revolution of the doffer continuing. We employ levers which are
sustained out of action by the intact sliver or by parts acted upon by the sliver but
are permitted to act when the sliver breaks and on such occurrence act upon parts
which unlock or release one of the side shaft bearings so that it can be moved to carry
the bevel pinion out of gear and so stop the revolution of the feed rollers. For this.
purpose and to prevent overfilling of the can we prefer to use a modification of the
stop motion for which Letters Patent number 2252 of the year 1876 were granted to
Joseph Dean but for the purposes of our invention we employ part of such motion to
act upon other parts which release the side shaft bearing as aforesaid. The manner
in which we propose to carry our invention into effect is indicated in the accom-
panying drawings. In the said drawings Fig. 1 represents a side elevation of part
of the doffer end of a Carding Engine and Fig. 2 represents a vertical section of the
upper part of the coiler head. Fig. 4 in Sheet 2 is a plan view partly in horizontal
section of the coiler and connected parts. In order to distinguish the parts which we
have adopted or modified from the aforesaid stop motion of Joseph Dean we have
marked such parts with the letters of reference which corresponding parts bear in the
Specification of his Invention.
h
of a
In Figs. 2 and 4o is the trumpet guide which is carried by the lever p which is fixed
upon the cross shaft
and is a second lever fixed upon the same shaft and connected
with the upper end of a wire m The lower end of this wire appears in Fig. 1
wherein it will be seen that the said wire is attached to one arm n¹ of a lever. This
arm of the lever tends to drop but is sustained in the indicated position by the wire.
The outer end of the said arm is hooked or bent at right angles this hooked end just
clearing a snug or projection which is formed upon the yielding member
clutch which is mounted upon the vertical shaft i of the coiler. The other member h¹
of the said clutch is fixed to the shaft and both members have driving teeth or pro-
jections which have inclined faces. The part is driven by the part so long as
the resistance to the revolving of the part is small but when there is a greatly
increased resistance the part yields in an upward direction. Such increased
resistance arises from the falling of the arm n¹ of the lever whereby the hooked end
of the said arm is brought into position to catch the snug and thereby to arrest the
revolution of the part of the clutch. When the part yields upward as aforesaid it
acts upon a lever g and rocks it upon its axis. A loaded catch lever t is employed to
hold the lever n n' in position to just clear the snug 1 so as to permit the engine to
work until the sliver can be brought through the trumpet guide. The slightly
increased lowering of the trumpet guide caused by the passage of the sliver has the
effect of raising the arm na little higher whereby the stop u of the arm n of the stop
lever is withdrawn from the end of the catch levert which then moves away from the
stop u as in Fig. 1 and thereafter the arm n¹ is sustained solely by the trumpet guide
acting through the lever and the wire m. These parts as so far described with
reference to the drawings we do not claim as new. In Fig. 1 a is the bearing bracket
in which is mounted the bearing block which carries one end of the side shaft b.
Fig. 3 is a side view of the said bracket and bearing block the side shaft appearing
in cross section. The bearing block a¹ is fitted to slide in a recess in the bracket so
as to move the driven bevel wheel c out of gear with its driver cas is usual in
some cases. When the wheel c is thus disengaged the revolution of the side shaft
ceases and as this shaft gives motion to the feed rollers the feed also ceases. There is
a tendency for the wheel e to be pushed out of gear but if considered to be desirable
we should apply a spring or load which would tend to slide the bearing block
in the direction which would disengage the bevel wheels. This tendency is
resisted by a detent lever d which locks the bearing block in position as seen
in Fig. 3. The said lever is mounted upon a fulcrum at d' and is formed with
a projection d² which prevents the sliding movement of the bearing block. It
will be seen that if the end of the arm d³ be lifted the projection d² will be

page_text: drawn downward out of the way of the bearing block. The said end d³ rests upon
one arm e of a lever which is mounted upon a fulcrum at e¹. The end of the other
9. The
arme of the said lever is connected by a link f with one arm of the lever
effect of this arrangement is that when the part / rises the arm e² is drawn down by
the lever g and the other arme by lifting the end d³ of the detent lever effects the
release of the bearing block so that the side shaft and the feed rollers are stopped.
It will be seen that this stoppage will follow a breakage of the sliver for the reason
that when the sliver ceases to pass through the trumpet guide o such guide will
rise whereby the arm n¹ will be lowered and the revolution of the part of the
clutch will be arrested the rising of such part resulting in the stoppage of the side
shaft in manner as aforesaid. The apparatus may be modified by connecting the
arm n' with a feeler lever which would be situated in any convenient position so
long as it could bear upon or be acted upon by the sliver so that the sustaining
of the said arm clear of the part h should depend upon the continuity of the sliver
such feeler lever taking the part of the trumpet guide o in so far as the stoppage
of the side shaft is concerned. We may further modify the apparatus by sustaining
the wire m or the arm n' by means of the top presser or calendering roller so that
when such roller descends on the breakage of the sliver the stop motion will be
brought into action. Fig 5 illustrates such a modification. In this example one
of the journals vis extended so as to support an armı m² which is attached to the
wire m or a lever resting upon the said journal may take the place of such arm
as indicated in Fig. 7. On the breakage of the sliver the top roller will drop and
will lower the rod m thereby bringing into action the parts which effect the stoppage
of the side shaft. It will be evident that this method may be greatly varied so
long as a feeler lever or arm resting upon the upper calendering roller or upon
one of its journals or upon each journal is connected with parts which sustain the
lever arm n¹. As hereinbefore mentioned the apparatus acts to stop the side shaft on
the can becoming full. The arrangement of the parts which act when the can is full
is illustrated by Fig. 6. A pinj is fitted to slide up and down in a bearing bored in
a swell upon the casting in which the bearing for one of the drawing-in rollers is
formed. The lower end of this pin rests upon the upper edge of the coilers and the
upper end is in contact with the lever p which appears in Figs. 2 and 4. When the
can becomes so full as that the contents lift the coiler s, the pin jis pushed upward
A similar arrange-
and by lifting the lever p effects the stoppage of the side shaft.
ment was mentioned in the aforesaid Specification of Joseph Dean but did not appear
in the drawings attached to such Specification but in our case the feed ceases when
the stop motion is brought into action through the complete filling of the can. We
may in some cases construct the apparatus without this provision for the stoppage of
the side shaft when the can becomes full.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is
1. The combinations of parts for stopping the feed rollers of a Carding Engine on
the breakage of the sliver or on the can becoming completely filled substantially as set
forth and indicated.
2. The bearing for the side shaft of a Carding Engine mounted to slide or move so
as to disengage the driving gear of such shaft but kept in its ordinary working
position by ineans of a detent lever in combination with parts for at times acting upon
such lever to release the bearing substantially as and for the purposes set forth and
indicated.
3. As applied to a Carding Engine the detent lever d locking the bearing a¹ and
moved from its locking position by the lever e e³ the end e² of the last named lever
being connected with the lever g in combination with parts for raising one end of the
last named lever on the breakage of the sliver and in some cases on the complete
filling of the can substantially as set forth.
4. As applied to a Carding Engine the detent d or a modification thereof keeping

page_text: in gear the bevel wheels which actuate the side shaft in combination with parts con-
trolled by a trumpet guide or a feeler lever or part and coming into action to withdraw
the said detent on the breakage of the sliver for the purpose set forth.
5. In a Carding Engine connecting the upper presser or calendering roller with the
lever n¹ in such a manner as that the dropping of such roller due to the absence of
sliver passing between the two rollers shall effect the lowering of the lever or arm n'
in connection with parts for stopping the rotation of the side shaft on the lowering of
the said arm substantially as set forth.
6. In a Carding Engine a lever or feeler sustained by the upper presser or
calendering roller and sustaining the drop wire or rod m substantially as and for the
purpose set forth and indicated.
