Improvements in Carding Engines.
I, WALTER BRIERLEY, of Central Chambers, Halifax in the County of York,
Patent Agent, do hereby declare the nature of this invention which has been
communicated to me by Egidi Moog, of Erlangen, in the Empire of Germany,
Master Carder and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention relates to improvements in machines for carding cotton and other
fibres, and consists of a new arrangement and combination of drums or cylinders
each of which is covered or clothed with card clothing and connected with a worker
and a clearer, the position of which worker and clearer between the drums or
cylinders being such that the worker has two working surfaces, and by such
arrangement the engine is made more compact a saving in room is effected, a better
inspection of the fibres under operation is afforded and when the sliver is broken
the engine is automatically thrown out of gear and stopped.
Such being the nature and object of my said invention the following is a
complete description of same, reference being had to the accompanying drawings
in which :-
Fig. 1 is a side elevation of my improved carding engine.
Fig. 2 is a cross sectional view of same.
Fig. 3 is a front elevation.
Fig. 4 is a plan view of such carding engine.
Figs. 5 and 6 are details of the appliance for self actingly stopping the machine
when the sliver is broken.
.
According to this my said invention, over the taker in D (Fig. 2) lies the first
drum A¹ and this touches only one worker B which is connected with a clearer C.
Both cylinders B and C touch the next drum A2 which likewise like the first drum
is connected with a worker and clearer. Then follows the next drum etc. till at
length the last A* is connected with the doffing-cylinder E. Between each of the
workers B. B. B. and the clearers C. C. C. there is a steel rail G. The edge of
this rail nearly touches the clothing of the both worker and clearer.
The diameter of the drums or cylinders is considerably less than those employed
heretofore and the number of workers B is less. The effect however, on the fibres
is efficient. The following is descriptive of the working process.
The material introduced to the feeding-roller H is first worked off by the "taker
in" D and then taken up by the drum A', which brings the fibrous material under
the cards of the slowly revolving worker B thereby producing a loosening or
opening of the fibres. This worker B then delivers the fibre to the clearer C In
this way the material crosses the steel rail G so that the knots or foreign substances
are kept back by it until a sufficient loosening or opening has taken place which
causes a more even distribution of the fibres. The material carried by the
clearer C is not in part sent back to the drum as heretofore, but is passed on to
the next drum A² which brings it again in contact with the first worker B. The
latter consequently presents two working surfaces, and in this manner represents
two workers, an arrangement which in connexion with the rail G produces a more
effective loosening than has hitherto been the case.
A part only of the fibrous material is taken by the second drum A² past the first
worker and the remaining part adheres to the worker and passes once more the
working place of the first drum A¹. The drums or cylinders are enclosed by wire
screens through the meshes of which the wind passes but through which cotton
cannot find an outlet.
As shewn and described there is a working process effected by two drums, a worker
and a clearer. The second and every following drum has two working surfaces.

The motion of all these cylinders is derived from the main shaft K which is
driven by means of a strap running over the pulley or disc K', with the neighbouring
loose pulley
or disc K and the disc while on the other end there are the discs K³
K' K. The disc K2 by means of a strap a causes the disc K to revolve and the
cog wheel 1 gears into a cog wheel E on the shaft of the doffer driving the latter
(Fig. 2). The disc K3 by means of a strap causes the cylinders A to revolve
(Fig. 1). The strap d running over the disc K drives the disc T on the
shaft of the comb T. The strap e of the disc K drives the disc D¹ of the
"taker in D (Fig. 1). Another disc D2 of the latter by strap / drives
the clearers C (Fig. 2). The workers B receive their motion from the shaft of
the doffer E, an endless chain passes round the chain discs 13₁ of the workers
and over a disc E2 of the doffer. The shaft of the upper of these workers B

eccentric on the shaft 3 turns within the frame 4¹ of a bar 4 which is linked with
the lower ends of the levers 6 (oscillating round fast pivots 5) of the cleaning
combs P. The latter are consequently caused to oscillate once at every rotation
of the shaft 3 Fig. 2. From the shaft of the doffer E is further derived the
motion of the feeding roller H, the bevel wheel 7 of the former gearing with the
wheel 8 of shaft 9 supported by the frame and a worm 10 gearing in a worm
wheel 11 on the shaft H. This feeding roller H also drives the finishers F, a
worm 12 (Figs. 2 and 4) on the shaft of the former gears with the worm wheel 13
on a shaft 14 and a worm 15 on this shaft 14 gears with a worm wheel 17 which
works on a fast stud 16. With this worm wheel 17 is connected a chain disc 18,
over which runs an endless chain h over the chain disc F1 of the finishers F
which deliver the waste noil, or short fibres to the cleaning combs P. In order
to secure requisite grip of the endless chain the stretching pulley 20 is employed
and is either fastened to the frame or supported by a weighted lever 19 (Fig. 2).
The automatic delivery of the sliver. is effected as follows. The sliver y is
delivered from the rolls to the sliver can 16 and falls by gravitation on a
pendulum R keeping it in one instance to the right (Fig. 5). If the sliver y is
broken the pendulum R swings to its normal perpendicular position and its lower
end rests against the end of a double armed lever S which turns on its fulcrum S'
attached to the frame (Fig. 6). This lever S is operated by an eccentric V and
caused to oscillate freely, but when the sliver breaks the pendulum R assumes the
perpendicular and the oscillation is stopped whereupon the elbow lever T' T2
placed between the eccentric V and the lever S moves sidewise and comes in
contact with the arm U which operates the second lever W (Fig. 2). This lever W
descends and throws the cog wheel 1 out of gear with the wheel E' and the further
delivering of fibre or sliver is arrested.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed I declare that what I
claim is :-
1. In a carding engine: The arrangement of two or more drums A¹ A² etc.) in
such manner that each drum is followed by a worker (B) which together with its
clearer (C) touches the next drum and having a steel rail (G) so placed against
the points of contact of the worker and clearer and their clothing all in combination
and as and for the purpose herein fully described and illustrated.
2. In a carding engine of the class referred to a stopping device comprising a
pendulum R, a double armed lever S, an elbowed lever T T all in combination
operating as and for the purpose herein fully described and illustrated by annexed
drawings.
