PROVISIONAL SPECIFICATION.
Improvements in Fulling Mills.
I, ERNST GESSNER of Aue, Saxony, in the Empire of Germany, Machine
Builder do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in fulling mills and has for its object to
improve or accelerate the fulling action and so increase the output of the machine
without correspondingly increasing the space occupied or the power consumed by
the machine.
With this object the side boards of the fulling trough are made movable and
operated in such manner that they are caused to act as beaters in the lateral
direction, their action being supplementary to and alternating with that of the
ordinary stock so that the fabric is worked or kneaded in two directions, in con-
sequence of which the fulling effect is greatly augmented and the goods are worked
more uniformly than hitherto. The piece is also prevented from forming knots
which is a great drawback to the existing fulling machine as it necessitates the
frequent removal of the goods from the trough for the purpose of stretching them.
The fulling stock may be suspended on a shaft and have oscillatory motion
imparted by a crank to which it is coupled by a connecting rod, or there may be
two stocks moved back and forth alternately.
According to one arrangement in which one stock is used, the two side boards
turn about vertical shafts, being secured to lever arms which are actuated through
toggle links connected by ball and socket joints with the connecting rod which
operates the stock and with the levers carrying the side boards whereby the latter are
moved inwards when the stock is drawn back and outwards when the stock is moved
inwards so that the goods are kneaded worked and turned alternately by the stock
in the ordinary way and by the side boards in the lateral direction whereby the
fulling effect is increased and rendered uniform. The side boards are of such shape
as to give free play to the stock in its to and fro motion and they may be divided
into two or more parts which may be moved to and fro in the lateral direction by
various means.

Improvements in Fulling Mills.
5 I ERNST GESSNER of Aue, Saxony, in the Empire of Germany, Machine
Builder, 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 :—
This invention relates, to improvements in fulling mills and has for its object to
O improve or accelerate the fulling action and so increase the output of the machine
without correspondingly increasing the space occupied or the power consumed by
the machine.

page_text: With this object the side boards of the fulling trough are made movable and
operated in such manner that they are caused to act as beaters in the lateral
direction, their action being supplementary to, and alternating with, that of the
ordinary stock so that the fabric is worked or kneaded in two directions, in con-
sequence of which the fulling effect is greatly augmented and the goods are worked
more uniformly than hitherto. The piece is also prevented from forming knots
which is a great drawback to the existing fulling machine as it necessitates the
frequent removal of the goods from the trough for the purpose of stretching
them.
The invention will be described with reference to the accompanying drawings,
forming part of this Specification, in which
Figure 1 shews a vertical longitudinal section and Figure 2 a plan of a crank
fulling mill provided with a single stock or beater.
H is the stock, of the ordinary stepped form, hung by arms on a shaft ✗
mounted in the frame G of the machine and oscillated within the trough S by n
crank K on shaft C to which it is coupled by a rod Z', the shaft C being provided
with fast and loose pulleyss and a fly-wheel F at either end. W W₁ are the
movable side boards of the said trough mounted to turn about shafts ¹³, these
side boards W W₁ being secured to lever arms Z Z the tail ends of which are
coupled by toggle links Z Z³ provided with ball and socket joints L L, L' L³,
with the connecting-rod Z' which thus operates both the stock and the side
boards WW' so that the side boards are moved inwards when the stock is drawn
back, as shewn in full lines in the drawing, and outwards when the stock is moved
forward, as shewn in dotted lines in Figure 2. By this means the goods are
kneaded worked and turned alternately by the stock in the ordinary way and by
the side boards in the lateral direction whereby the fulling effect is increased and
rendered uniform. The axes X'X' about which the side boards swing are inclined
in a plane at right angles to the connecting rod Z' when the crank K is at the
dead point and the side boards are curved or hollowed out, as shewn, so as to give
free play to the stock in its to and fro motion.
The side boards may be divided into two or more parts which may be moved to
and fro in the lateral direction by various means, and I do not limit myself to a
single stock as a pair of stocks may be employed, working backwards and forwards
alternately within the trough.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
"
1. In a fulling mill, the combination, with the trough and with, the stock
reciprocated, therein, of movable side boards operated in such manner that they act
as lateral beaters whose movements alternate with that of the stock and whose
action supplements that of the stock, substantially as specified.
2: In a crank fulling mill, the combination, with the stock and with its crank-
operated connecting rod, of side boards mounted to oscillate laterally on axes and
provided with tail pieces or lever arms, and of toggle links with universal joints
coupling said tail-pieces, with the connecting rod. which operates the stock,
substantially as specified.
