Carding Engines.
1, CARL OSWALD LIEBSCHER of Gera, in the Principality of Reuss, Empire of
Germany, Manufacturer do hereby declare the nature of this invention to be as
follows:-
My invention relates to a mechanism to be employed in connection with a
balance to weigh the quantity of wool or other fibrous material fed to a carding-
engine, the purpose of this mechanism being to stop the supply of material as soon
as the deflection of the balance has reached a certain limit. The object of my
invention is to provide a mechanism of increased sensibility, which is of great
importance, as in machines of the same kind as constructed hitherto variations up
to 20% from the proper quantity to be supplied could not be avoided entirely.
The means which I employ for attaining this object consist of several levers and
counterweights, and I will proceed to describe my invention by the aid of the
accompanying drawings, in which
Fig. 1 is a front elevation of that part of a carding-engine to which my improve-
ments relate.
Fig. 2 is a side elevation of the same, partly in section.
Figs. 3 to 6 are detail views drawn to an enlarged scale, of several parts of my
improved mechanism.
Similar letters refer to similar parts throughout the several views.
Referring to the accompanying drawings, BC are the beams of the balance
resting on knife-edges A and provided one on each side of the machine. B is the
arm carrying the weights, and C the arm from which the scale or basin D is
suspended. The wool or other fibrous material is fed to the basin D in the usual
manner from a receptacle placed at the bottom of the frame Y by means of an
endless belt passing over the pulleys X and V. To the beams B C is attached a
bent lever F pivotted at E (this lever is shown in detail at Figs. 3 & 4).
Lever J F is provided with a counterweight F1 which keeps it normally in contact
with a stop G, so that the arm J will be vertical. A pin or bolt Z is secured to
the frame of the machine, and a click M, provided with a counterweight L, and a
small lever N are loosely and independently mounted on the said pin; the click M
is also connected to a lever K, and has a flat projection M' formed on its inner side,
with which the extension N¹ of the lever N is adapted to collide. The lower
end K of lever K is bent (see Figs. 2 & 4) and bears against the vertical face of a
nose on the arm J, as long as the beams B C are horizontal. In this case the
click M with its counterweight L occupies the position shown by full lines, so that
the click does not engage with the ratchet-wheel U and the latter may freely
rotate together with the pulley V. As the scale D is gradually filled with wool or
any other material, it sinks down and the beams B C assume the position shown by
dotted lines, the nose of the lever J rises above the vertical face on the end K' of
the lever K (Fig. 4), and the latter, by the action of the counterweight L, glides
under this nose, so that the click M, being released, snaps into the ratchet-wheel U
and stops the motion of the same, and simultaneously the supply of material to the
scale D. The contents of the latter are delivered in the usual manner on the
spreading-table of the carding-engine.
The disc S provided with a pin or stud R and continuously rotated by means of
the endless chain T effects an intermittent lateral motion of the bent lever Q P
once at each rotation of the disc. The lever N is thereby drawn downwards, by
neans of the connecting-rod O. The extension N' of the said lever N will then
ΓΟ

page_text: collide with the projection M³ on the click M and thus withdraw the latter from
the ratchet-wheel U; the feeding-device will therefore again begin to move.
Simultaneously the lever K will oscillate round the pivot Z and return from the
position, indicated by dotted lines into the initial position and will even move
somewhat farther. In this movement, the end K' of the lever K comes in contact
with the nose on the lever J and thereby brings the bent lever J F from the
position shown in full lines into that indicated by dotted lines at the left of Fig. 3,
so that the lever J strikes against the stop H. As soon as the lever J F is
released, the weight F brings the same back to its initial position. When the
bent lever PQ is no more influenced by the pin R, the weight L asserts its power
to replace the lever K in its original position, that is to say, turns the same back
till it strikes against the nose of the lever J.

COMPLETE SPECIFICATION.
Improvements in or connected with Feeding Machines for Carding
Engines.
J, CARL OSWALD LIEBSCHER of Gera, in the Principality of Reuss, Empire of
Germany, Manufacturer do hereby declare the nature of this invention, and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
My invention relates to a mechanism to be employed in connection with a balance
to weigh the quantity of wool or other fibrous material fed to a carding-engine,
the purpose of this mechanism being to stop the supply of material as soon as the
deflection of the balance has reached a certain limit. The object of my invention
is to provide a mechanism of increased sensibility, which is of great importance, as
in machines of the same kind as constructed hitherto variations up to 20% from
the proper quantity to be supplied could not be avoided entirely.
The means which I employ for attaining this object consist of several levers and
counterweights, and I will proceed to describe iny invention by the aid of the
drawings sent in with Provisional Application, in which
Fig. 1 is a front elevation of that part of a carding-engine to which my improve-
ments relate.
Fig. 2 is a side elevation of the same, partly in section.
Figs. 3 to 6 are detail views, drawn to an enlarged scale, of several parts of my
improved mechanism.
Similar letters refer to similar parts throughout the several views.
Referring to the drawings B C are the beams of the balance resting on knife-
edges A and provided one on each side of the machine. B is the arm carrying the
weights, and C the arm from which the scale or basin D is suspended. The wool
or other fibrous material is fed to the basin D in the usual manner from a receptacle
placed at the bottom of the frame Y by means of an endless belt passing over the
pulleys X and V. To the beams C B is attached a bent lever J F pivotted at E
(this lever is shown in detail at Figs. 3 & 4). Lever J F is provided with a
counterweight F' which keeps it normally in contact with a stop G, so that the
arm J will be vertical. A pin or bolt Z is secured to the frame of the machine,
and a click M, provided with a counterweight L, and a small lever N are loosely
and independently mounted on the said pin, the click M is also connected to a
lever K, and has a flat projection M' formed on its inner side, with which the
extension N of the lever N is adapted to collide. The lower end K' of lever K is
bent (see Figs. 2 & 4) and hears against the vertical face of a nose on the arm J, as
long as the beams B C are horizontal. In this case the click M with its counter-

page_text: weight L occupies the position shown by full lines, so that the click does not engage
with the ratchet-wheel U and the latter may freely rotate together with the
pulley V. As the scale D is gradually filled with wool or any other material, it
sinks down and the beams B C assume the position shown by dotted lines, the nose
of the lever J rises above the vertical face on the end K' of the lever K (Fig. 4)
and the latter, by the action of the counterweight L glides under this nose, so that
the click M, being released, snaps into the ratchet-wheel U and stops the motion
of the same, and simultaneously, the supply of material to the scale D. The
contents of the latter are delivered in the usual manner on the spreading-table of
the carding-engine.
The disc S provided with a pin or stud R and continuously rotated by means
of the endless chain T effects an intermittent lateral motion of the bent lever QP
once at each rotation of the disc. The lever N is thereby drawn downwards, by
means of the connecting-rod O. The extension N¹ of the said lever N will then
collide with the projection M' on the click M and thus withdraw the latter from
the ratchet-wheel U; the feeding device will therefore again begin to move.
Simultaneously the lever K will oscillate round the pivot Z and return from the
position indicated by dotted lines into the initial position and will even move some-
what farther. In this movement, the end K' of the lever K comes in contact with
the nose on the lever J and thereby brings the bent lever J F from the position
shown in full lines into that indicated by dotted lines at the left of Fig. 3, so that
the lever J strikes against the stop H. As soon as the lever J F is released, the
weight F brings the same back to its initial position. When the bent lever PQ
is no more influenced by the pin R, the weight L asserts its power to replace the
lever K in its original position, that is to say, turns the same back till it strikes
against the nose of the lever J.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
A self-acting stopping-device for the automatic feed-apparatus of carding-engines,
consisting of a bent lever JF, pivotted at the beam of the balance A B and
provided with a counterweight F, said lever being connected with a click M,
serving for stopping the supply of material and being released at the rising of the
beam of the balance A. B by a nose on one arm of the bent lever J F, further
consisting of a mechanism, composed of the bent Q P and the connecting-rod O,
serving for withdrawing the click M from the ratchet-wheel U, when the scale D
emptied, for the purpose as described.
