COMPLETE SPECIFICATION:
Improvement in Fulling-engines.
I, CARL WELTE, Workmaster of Neustadt on the Hardt in the Province of
Rhineland and Kingdom of Prussia 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 invention now to be described concerns an arrangement in fulling-engines-
by which it is made possible to expose the stuffs that are to be milled for an
accurately fixed length of time to the action of fulling-arms, the apparatus putting
the fulling-arms out of gear with the driving-mechanism after the completion.
of the desired number of rotations of the fulling arms and thus causing them,
to stop.
Fig. 1 and 2 show the apparatus in upper and side-view.
Before the end of the fulling arm, which is not drawn here, there is an arm b₁,
which is raised by the oscillations of the fulling arm and after the latter has been
released, is drawn downwards again by a spring 1.
On b, there is a pawle which at each forward and backward motion moves a.
toothed-wheel R, which is in gear with it, one tooth further on, the wheel being.
prevented from going back by a pawl c.
The wheel R is made with 100 teeth as one reckons about 100 blows per minute..
A cam-disk f, which is firmly connected with the wheel R pushes at each
rotation a lever e into the teeth of a second toothed-wheel R₁, thus moving on the
latter one tooth at each rotation. The wheel R, is divided according to the
number of teeth and has a button K with a cam g mounted above it. An index-
pin h catches above into the teeth of the wheel R₁, and above there is a lever a:
which is suitably connected with the coupling lever m of the driving-belt disk.
The apparatus works in the following manner :
Let us suppose that the milling is to last 20 minutes and that the stuff to be
milled is to receive 2000 blows in this time.
One turns the wheel R₁, taking hold of it by the button K froin right to left,.
until the index-pin stops in the tooth marked 20 (vide Fig. 1) then the machine
is started to work.
At each blow of the fulling-arm the wheel R is turned round one tooth further
and with it the cam-disk f.
As soon as R has made a rotation, the cam comes against the pin e and raises
it, while turning it a little at the same time, upwards into the opposite tooth of the
wheel R, and thus moves it one tooth further on.
As soon as the cam releases the peg, it darts back owing to the force of a spring
connected with it and exercises the same effect on the wheel R₁ after each further
rotation of R. The wheel R₁ is thus turned one tooth further to the left after
each rotation of R.
When the wheel R has made 20 rotations in this manner, the lifting-iron 9 goes
past the index-pin k under the lever a and raises it from its position of rest, thus.
turning the lever a around the hinge m. Thereby the belt contained in the
belt-fork n is drawn to the left from the fixed pulley to the loose pulley. This
throws the mechanism out of gear and the fulling-arms immediately stop.
Having now particularly described and ascertained the nature of my said.
Invention and in what manner the same is to be performed, 1 declare that what.
I claim is:
In fulling-engines an apparatus for causing the fulling-arms to stop automatically

page_text: after a certain time of working, distinguished by the lever b₁, actuated from the
fulling-arm, with the pawl c, the ratchet wheel R with the cam f, the spring-levere,
the wheel R₁ provided with teeth and lifting-iron, the index h and the lever a
connected with the disengaging gear, acting in such a manner, that by means of
the lever by actuated by the stroke of the fulling-arm, the toothed wheel R and the
cam-disk f, and by means of these the arm e and the wheel R, is moved until the
lifting-iron of the wheel R, throws the lever a out of gear and the driving-belt is
thereupon brought by the latter on to the loose pulley.
Dated this 22nd day of June 1895.
