Improvements in Carding Machines.
We, RUDOLF BÖTTGER and OSWALD ZEUNERT of Leisnig, in the Kingdom of
Saxony, Empire of Germany, Manufacturers, do hereby declare the nature of this
invention to be as follows:-
This invention relates to an apparatus for efficaciously removing the waste
substances from carding machines and has for its purpose to obviate the danger to
the attendants connected with the removal by hand, during work, of the waste
matter thrown off the clearers and to ensure at the same time a better and more
uniform product.
The improved apparatus is in the main disposed as follows.
In a tin box is lodged parallel to the clearer a shaft to which is secured a flat-
iron knife or cutter. Said knife lies with its upper edge as close as possible to the
clearer so that the impuritics of the cards strike against the knife and fall onto the
latter or into the box.
The knife is moved automatically at certain intervals by means of the hereafter
described mechanism. On the pivot of one of the working cylinders is secured a
cord whirl, from which are rotated by a cord another whirl and a worm wedged on
the same shaft as the latter. The worm slowly rotates, by aid of a worm wheel, a
shaft extending towards the tin box referred to and provided with a lever at the
end. This lever when the shaft is revolving strikes against an angle lever, which
has a nose or projection at the other end. Said nose serves to hold the knife
against the clearer and by the action of the shaft lever, is turned away from, and
releases, the knife, which is then turned for a certain distance about its shaft by a
leaf spring pressing against a bolt connected with the nose side of the angle lever,
said movement of the knife being determined by an indiarubber disc or buffer
attached to the tin box. By this alteration of the position of the knife, the waste
matter accumulated thereon is thrust into the box and the waste matter already
collected in the latter is moved on.
To the shaft of the next lower working cylinder is attached a cam or lifter
adapted to strike on a finger or kneed tappet, secured to the knife shaft, thereby
returning knife and spring to their former position. At the last moment of this
movement, the nose of the angle lever places itself again behind the knife and in
sliding, by the action of a spring provided for this purpose, along a slanted surface
of the knife, it presses the latter and also the finger referred to a little further than
can be effected by the lifter of the next lower working cylinder, whereby the lifter
is prevented from striking the bottom end of the finger at every revolution of the
working shaft.
The knives of the other clearers are moved from the above mentioned knife by
means of suitable angle lever transmission devices.

Improvements in Carding Machines.
We, RUDOLF BÖTTGER and OSWALD ZEUNERT of Leisnig, in the Kingdom of
Saxony, Empire of Germany, Manufacturers, 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 an apparatus for efficaciously removing the waste
substances from carding machines and at the same time obviating the danger to the
attendants, which is connected with the removal by hand, during work, of the waste
matter thrown off the clearers, the rapidly operating clearer being apt to pull in the
hand or even the arm of the attendant.
The regulation to previously stop the carding machines is generally disregarded
owing to the waste of time entailed thereby; or the wool dust is removed from the
protecting board only during the daily intervals of work, whereby the waste
substances are too much accumulated and are taken along again by the clearer,
which is of a very injurious influence on the fabrik.
In order to allow the waste substances to be removed during work from the
clearers without any danger to the attending person, we apply to the carding
machines the device represented in the accompanying drawings Sheets I and II,
in which
Fig. 1 is a front view of a carding machine provided with the new apparatus.
Fig. 2 is a rear view thereof.
Figs. 3, 4 and are respectively a front view, side view and plan of the
mechanisms serving for moving the knife m.
In a sheet metal box a is arranged, parallel to the clearer w, a shaft b to which is
secured a flat iron knife m. The latter lies with its upper edge as close as possible
to the clearer, so that the waste substances retained in the cards strike against said
edge and fall off the clearer and upon the knife or into the box.
The knife is moved automatically at certain intervals by the hereafter described
mechanism.
On the pivot of one of the working cylinders A is mounted a cord whirl k from
which are rotated by means of a cord the whirl and worm secured on the same
shaft therewith. The worm is geared with the worm wheel thereby imparting a
slow rotation to the shaft and to the lever fixed thereon.
As soon as lever / has brought the angle lever into the position indicated by
dotted lines in Fig. 3, the nose provided at the other arm of this lever recedes from
the knife m, which up to that period was held by said nose against the clearer w,
and the weight g brings the knife m into the position indicated by dotted lines in
Fig. 4 and determined by the indiarubber buffer p attached to the box whereby
the waste substances lying on m are thrown into the said box, while the waste
matters already contained in the box are shifted on.
a,
The working cylinder A¹ situated below the upper box a has attached thereto a
pege which strikes against finger d connected with shaft band brings said finger
together with knife m from the position shewn by dotted lines in Fig. 4 into that
drawn in plain lines.
At the last moment of movement the nose n Fig. 5 again moves behind the
knife m, and, sliding by the action of spring f2 along a slanted surface of the
knife m,
it presses the latter and also the finger d slightly farther than can be done
by pege, whereby said peg is prevented from striking at every revolution of the
working cylinder the bottom end of finger d.
The knives of other clearers, for instance m', are operated from knife m by a
lever Fig. 2 connected by cranks o and o¹ or equivalent with the knives m and m¹.
The size of the boxes is so determined, that no excessive filling thereof can take

page_text: place if they are emptied at noon and in the evening after the carding machines
have been stopped.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
A device for removing the waste substances in carding machines, in which the
knife m revoluble about its lower rim and receiving the waste substances is folded
over from time to time, throws the waste substances lying thereon into the box a
and shifts along the waste matter accumulated therein, whereby the removal of said
substances is only necessary in the ordinary intervals of work, substantially as and
for the purpose set forth.
