Improved Device for the Transmission of a Rotary Motion in
Eccentrically Shaking and Oscillating Machines.
I, ANDREAS HUGO CHRISTIAN LAUTE, a Subject of the Emperor of Germany, of
No. 39, Beusselstrasse, Berlin, in the Empire of Germany, Engineer, do hereby
declare the nature of my said invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following state-
ment-
This invention relates to a device for the transmission of a rotary motion in eccen-
trically shaking and oscillating machines, as, for instance, in plane sifters and the
like. This device has for its object the driving of rotating parts as for instance,
ventilators, creepers, disintegrators or the like, in connection with the said machines.
For this purpose an eccentrically mounted driving mechanism is, according to the
present invention, rigidly connected to the driving shaft, which driving mechanism
may be constructed as pulley, friction wheel, toothed wheel or the like.
In the accompanying drawings there are shown two modified constructions of the
new device in connection with a plane sifter suspended in the usual manner, such
driving mechanism, which is coupled with the driving shaft, being constructed as a
pulley and adapted to drive a ventilator.
In the modification according to Fig. 1, which is a sectional view of the device, a
pulley bis eccentrically mounted directly on the driving shaft & or rigidly connected
therewith. The pulley carries an axial bearing, in which is mounted the crank pin c
engaging with the plane sifter a vertically from below.
On the rotation of the shaft d, the pulley b is positively carried therewith, and
makes a rotation round the central line of the axle d, thus eccentrically to its own
central line. In consequence of this motion, the crank pin c receives a rotary motion,
whereby the elastically suspended plane sifter a effects eccentrically shaking oscilla-
tions, whilst the rotating motion of the pulley b may be transmitted to one or more
pulleys by means of belt driving mechanism and consequently may be used for
driving ventilators, creepers, disintegrators or other rotating devices in connection
with the plane sifter.
In the modification according to Fig. 2, which likewise is a sectional view of a
modified device, the crank pin is adjustably arranged against the driving shaft and
for this purpose, a clutch is provided between the driving shaft and the driving
mechanism adapted for transmitting the rotary motion.
The pulley is rotatably mounted on the crank pin and provided below with
recesses, in which engage clutch pins f rigidly connected with the driving shaft d.
The adjustment of the crank pin is effected by means of a screw spindle, mounted in
a sleeve provided axially on the driving shaft. The adjusting device is of no moment
for the essence of the invention and therefore not explained in detail.
On the rotation of the shaft d, the pulley b is carried along by the clutch pins f
and the above described operation is thereby effected.

page_text: 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
1. In a device for the transmission of a rotary motion in eccentrically shaking and
oscillating machines and the like, the combination of the driving shaft with an
eccentrically mounted driving mechanism (pulley, friction wheel, toothed wheel or
the like) and a positive connection between the shaft and the driving mechanism,
substantially as and for the purpose set forth.
2. In a device for the transmission of a rotary motion in eccentrically shaking and
oscillating machines and the like, the combination of the driving shaft with ap
eccentrically mounted driving mechanism and a rigid connection between the shaft
and the latter substantially as and for the purpose set forth.
3. In a device for the transmission of a rotary motion in eccentrically shaking and
oscillating machines and the like, the combination of the driving shaft with an
eccentrically mounted driving mechanism, a clutch between the shaft and the driving
mechanism and an adjusting device for the latter substantially as and for the purpose
set forth.
