Improvements in Centrifugal Machines.
I, PAUL REUSS, of Artern, Prussia, in the Empire of Germany, Factory Owner,
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 :―
Hitherto in all centrifugal machines the supporting shaft for the drum also con-
stituted the driving shaft. In the present construction there are arranged two
shafts, of which neither is fixedly connected with the centrifugal vessel.
In the annexed drawing Fig. I shows a vertical section of the apparatus, and
Fig. II another form of construction of the driving shaft.
The drum is seated loosely by means of a hollow cone B¹ on a supporting shaft
B, whilst the movement is effected by a movable and pendulant axle C operated
from above.
In Fig. 1 the shaft C is arranged displaceably in a socket of the driving pulley G
and suspended by means of a bolt or the like Gi in a pendulum like manner in the
latter, so that the drum can move freely without influencing the impulsion. By
lifting the shaft C the drum A can be removed.
The shaft C operates the movement of the drum A. by means of a groove or the
like at the lower extremity of the same operating on a transversal bolt B² fixed in
this hollow cone B¹ of the drum A.
Fig. 2 shows another example of construction of the driving shaft in which the
some consists of two parts D and E of which D is fixed at its upper end to the
driving pulley, and E displaceable in itself, is connected pendulantly with D at its
upper end, and at its lower end with the drum A as in Fig. 1 before described. It
can be removed from the drum after having overcome the pressure of an inserted
spring F.
By means of this arrangement for the transmission of movement the vibration
caused by the impulsion is avoided, and the driving axle can be of small dimen-
sions, any unnecessary friction is avoided and an easy working of the machine is
attained. The driving shaft can be removed during the working, so that the drum
can rotate freely.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I
claim is :-
1. In centrifugal machines the arrangement of a detachable driving device in
such a manner, that the centrifugal drum running on a pivot bearing carries above
the supporting point a driver, which is engaged loosely by a spindle for the purpose
of impulsion, so that the drum is allowed during the motion to oscillate in which
movement the driving shaft does not participate.
2. In centrifugal machines the arrangement of a driving spindle which is con-
nected in such a manner both with the driving means and also with the centrifugal
drum without elastical means, that oscillations of the same are transferable neither
to the driving means, nor to the centrifugal machine.

page_text: 3. In the driving shaft in centrifugal machines as in Claims 1 & 2 means for dis-
engaging during motion wherein (a) the spindle is connected loosely with the driv-
ing device equally by a driver, so that by lifting the spindle the connection between
the centrifugal drum and spindle as well as between the driving device and spindle
ceases; or (b) the spindle is made of several parts engaging with one another of
which the first part connected fixedly with the driving device operates the other or
others by means of drivers, a telescope like displacement of the single spindle parts
permitting the spindle to be slid together for the purpose of disengagement.
