I, CARL COERPER of Ehrenfeld near Cologne on the Rhine in the Empire of
Germany do hereby declare the nature of this invention to be as follows:-
This invention consists essentially in the combination with a machine generator of
electricity of a fly wheel disc or other mass as may appear necessary for maintaining
an uniform motion and consequently a proper operation of the machine.
This invention does not apply to those machines in which the arrangement and the
weight of the armature iron and windings or of the field magnets and wire coils are
sufficient as a fly mass for attaining the requisite degree of uniformity or in which the
generator of electricity is mounted upon the shaft of the motor or coupled thereto.
According to this invention the fly wheel, disc or the like must be connected either
with the armature or the field magnets of the generator of electricity. The fixing can
be effected by means of the spokes of the wheel or the web of the disc or of the ring
of the wheel or disc.
The fly wheel or fly disc has no direct magneto electric function, its importance
being rather in the attainment of the requisite degree of uniformity of the
circumferential velocity.

Improvements in Dynamo-electric Machines.
I CARL COERPER of Ehrenfeld near Cologne on the Rhine in the Empire of
Germany, Engineer 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 :-
This invention relates to dynamo-electric machines, and consists essentially in the
combination with the armature or the field magnets of such a machine of a fly-wheel,
disc or other mass as may appear necessary for maintaining a regular motion and
consequently an uniform tension at the terminals, the said wheel or the like having no
direct magneto-electric function.
This invention does not apply to those machines in which the arrangement and the
weight of the armature cores and winding, or of the field magnets and wire coils, are
sufficient as a fly mass for attaining the requisite degree of uniformity; or in which
the generator of electricity is mounted upon the shaft of the motor, or coupled
thereto.
According to this invention the fly wheel, disc or the like must be connected either
with the armature or the field magnets of the generator of electricity. The fixing can
be effected by means of the spokes of the wheel, or the web of the disc, or of the ring
of the wheel or disc.
The fly wheel or fly disc has no direct magneto electric function, its importance
lying rather in the attainment of the requisite degree of uniformity of the
circumferential velocity.
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 I claim is :—
The combination with the armature or field magnets of a machine generator of
electricity of a fly wheel, disc or the like, which has no direct magneto electric action,
the said armature or the field magnets being fixed to the fly mass in such a manner
that the degree of uniformity of the circumferential velocity, that is required for a
constant tension at the terminals, is maintained.
