A New or Improved Shaft Coupling or Olutch.
I WILHELM ASBECK Manufacturer of Rheydt in the Kingdom of Prussia and
German Empire 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 object of this invention is the instantaneous coupling and dis-connection of
two shaft parts a driving part I and a driven part II of the axes.
Figure 1 is a longitudinal section of my new or improved coupling.
Figure 2 is a view of B with the radial guides of the cog flange parts and friction
surfaces c.
Figure 3 is a view of E with the eccentric grooves which guide the friction surfaces
and the cog flange parts.
Figure 4 is a view of the coupling in connection with the brake i.
Through the coupling part B wedged or otherwise rigidly fixed on to the axis I
the radially movable friction and cog flange parts c are forced into the rotary move-
ment which the axis I makes. If the ring E which is pinned or secured loose upon
the coupling part B and is only kept in its position by the adjusting ring H be
held tight by pulling the brake i the cog flange parts c while making the same
rotary movement as B will be compelled to take a path separating from the centre
and nearing it again-in the portion of this path furthest removed from the centre
the teeth of the cog flange k gear with the teeth of the cog flange parts c and if at
that moment the brake is taken off the ring E the firm connection of the couplings A
and B is effected. By the return of the cog flange parts in the guides the firm
connection is severed and this is attained by again holding fast the ring E. On the
coupling part A the ring m is fastened and is connected elastically with A it bears
the oblique surface n which bears against or towards the oblique surface e of the cog
flange parts c at the same angle. By the removal of the wheel flange parts e from
the centre there is created a pressure of the surface e from c on the surface n of the
ring m and thus a friction of these parts is caused which guards against a sudden
gearing of the teeth of the cog flange k and the cog flange parts c.
It will now be seen that by holding fast the ring E one obtains both the connection
of the axis II with the motion of the axis I and also the disconnection thereof as
the case may be.
As these manipulations only occupy an instant not only can the shaft part II be
instantaneously connected by electro magnetic action for instance but it can also be
disconnected by a similar second action.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what 1
claim is :-
A friction and cog coupling in which the radially moveable parts c upon being slid
outwards can first of all be geared by cone friction surfaces e n with the ring m and
hen by outer cog sections with the inner cog flange of the coupling part A to be
carried with them and in which the sliding of the parts c is effected by the gearing
hereof with the eccentric grooves f of the ring E which latter is to be braked by
tself and which revolves on the driving part B substantially as hereinbefore described
nd shown in the drawing hereunto annexed.
