PROVISIONAL SPECIFICATION.
Improved Friction Coupling.
A communication by GEORG STEPHAN REINHARDT and EDUARD WILHELM
MESSMER, both of Flensburg, in the Empire of Germany, Engineers.
1, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool and 6, Bank Street,
Manchester both in the County of Lancaster and 323, High Holborn, in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this inven-
tion to be as follows:-
This improved coupling is specially applicable for vertical spindles supporting
beavy weights. It is a conical coupling. The cone is composed of several parts
having spaces between them. The end of the spindle entering this cone is enlarged
and of spherical form.
The above mentioned cone is placed in a hollow cone forming a part of the mass
to be coupled and supported.
The weight of the swinging mass forces the cone composed of separate parts to
adapt itself constantly and automatically to the spherical end of the spindle and
the walls of the hollow cone.
This improved coupling may be placed at the upper and the lower end of the
spindle, if desired.

1, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors 6, Lord Street, Liverpool, and 6, Bank Street,
Manchester, both in the County of Lancaster, and 323 High Holborn in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
This improved coupling is specially applicable for vertical and well loaded free
moving spindles.
In the accompanying drawings
Figure 1 represents the coupling mechanism in sectional elevation.
Figure 2 is a section on line x-y (Figure 1).
The principal part of this coupling is the cone or conical cushion a composed of
several parts having spaces between them.
The end u of the vertical spindle w entering into this cone is enlarged and of a
spherical form.

The above mentioned cone a is placed in a hollow cone y forming a part of the
mass m to be coupled and supported.

page_text: The weight of the rotating mass m forces the cone a (composed of separate
parts) to adapt itself constantly and automatically to the spherical end u of the
spindle w and the walls of the hollow cone g.
As shown in the drawing, this coupling may be placed at the upper and the
. lower end of the spindle w if desired.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is :-
An automatic friction coupling characterized by a cone or conical cushion a
composed of several parts and adapted to receive the enlarged spherical end u of
the vertical spindle w and held together by a hollow cone g formed in the rotating
mass m substantially as described and illustrated.
