PROVISIONAL SPECIFICATION.
Improved Apparatus for Periodically Producing Electric Current by
Means of Irregular Motive Power.
I MAX GEURE, of Bismarck Strasse, Rath, near Düsseldorf, in the Empire
of Germany. Engineer, do hereby declare the nature of this invention to be as
follows:-
Many forces acting sometimes strongly and sometimes feebly, such for
instance as the power of the wind, are unsuitable for many industrial purposes,
more particularly where it is a question of not exceeding a given maximum
speed. This in certain instances is the case in producing electric current, more
particularly for the charging of accumulators, as if a given speed be exceeded
in this case interruptions in the current conductors of the dynamo machine are
to be feared.
This invention has for its object an apparatus for producing electric current
by means of motors driven by irregular power and which comprises a chain
pulley or chain pulleys over which an endless chain (or chains) carrying a weight
or weights is passed, and which is operated from the motor by means of a catch
or pawl and stop or projection until the weights carried over the pulley (or
pulleys) drop and effect a longer lasting and always equally maintained further
movement in which the pawl or catch disengages the stop or vice versa and then
again comes into engagement for the next lifting of the weights.
In carrying the invention into effect, a shaft which is operated with irregular
driving power from a motor which need not be described is adapted by means
of a small cog-wheel or pinion to drive a large cogwheel which is loosely mounted
on a shaft on which two chain pulleys connected with one another by means of
a long hub are fixed. Over these chain pulleys run endless chains which lower
down run over a pulley and carry weights arranged as closely as possible to
one another, which weights are mounted on both chains with link bolts so as to
be connected one to another.
The pulley shaft in order to produce current is periodically rotated by the
action of the weights with an always equal movement when the weights are moved
over the chain pulleys. On the large cog wheel a pawl is mounted which is
pressed by a spring against one of the two chain pulleys and a stop or projection is
provided on the chain pulley in the path of said pawl to be engaged thereby. By
rotating the cog wheel the said rotation is transmitted to the chain pulleys
which are firmly connected with one another, and thereby a lifting of the weights
takes place periodically. When the weights pass over the chain pulleys they
cause a further rotation of said pulleys and the shaft by their gravity, in order
to produce the current, and having arrived below at the bottom pulley are again
raised by the engagement of the pawl on the stop or projection of the chain
pulley.
On the descent of the weights, as the chain pulleys would rotate more rapidly
than the cog wheel, the pawl disengages from the stop or projection, and when

page_text: the said rotation of the pulleys is completed it again encounters the stop. In
this manner by the periodic action of the weights, an always equal rotation
of the shaft is effected.
The cog wheel might also be firmly mounted on the shaft and then the chain
pulleys must be loosely revoluble on said shaft. The latter could not then
serve for producing current, but a separate driving connection with the chain
pulleys must be made in order to rotate a shaft serving to produce the current.
This may be easily effected by arranging a spur wheel on the outside of one of
the chain pulleys, through which wheel the rotation would be transmitted to a
spur wheel on the shaft to be driven.
In another form of construction only a single chain wheel need be fixed on
the shaft which is to be evenly operated periodically. The link bolts are in
this case prolonged beyond the pulley to both sides in order to carry a weight
on each prolongation. Opposite the catch 'pawl which is carried by the spur
wheel there is a disc carrying the stop or projection, said disc being made in
one piece with the hub of the chain wheel. Otherwise the arrangement is
In this case also the endless chains carrying the weights travel over
pulleys lying at a lower depth. The lower pulleys may also be omitted but in
that case care must be taken by arranging safety devices over the upper pulleys
that the chains do not come out of connection with the pulleys.
the same.
Of course the pawl might also be arranged on the chain pulley or the disc
connected therewith, whilst a fixed catch or stop may be arranged on the spur
wheel but this alters nothing in the essential idea of the invention.

Improved Apparatus for Periodically Producing Electric Current by
Means of Irregular Motive Power.
I, MAX GEHRE, of Bismarck Strasse, Rath, near Düsseldorf, 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 ascer-
tained in and by the following statement:-
Many forces acting sometimes strongly and sometimes feebly, such for
instance as the power of the wind, are unsuitable for many industrial purposes,
more particularly where it is a question of not exceeding a given maximum
speed. This in certain instances is the case in producing electric current, more
particularly for the charging of accumulators, as if a given speed be exceeded
in this case interruptions in the current conductors of the dynamo machine are
to be feared.
This invention has for its object an apparatus for producing electric current
by means of motors driven by irregular power and which comprises a chain
pulley or chain pulleys over which an endless chain (or chains) carrying a weight
or weights is passed, and which is operated from the motor by means of a catch
or pawl and stop or projection until the weights carried over the pulley (or
pulleys) drop and effect a longer lasting and always equally maintained further
movement in which the pawl or catch disengages the stop or vice versa and then
again comes into engagement for the next lifting of the weights.

form of construction with two chain pulleys;

o

Figures 6, 7 and 8 show on a reduced scale the device for guiding the weight
chain in different positions of the chain and with an under chain pulley.
In carrying the invention into effect, in the example shown in Figures 1-3
a shaft a which is operated with irregular driving power from a motor which
need not be described is adapted by means of a small cog-wheel or pinion b
to drive a large cogwheel c, which is loosely mounted on a shaft d on which
two chain pulleys e connected with one another by means of a long hub are
fixed. Over these chain pulleys e run endless chains f, which lower down run
over a pulley h, Figures 6, 7 and 8, and carry weights i arranged as closely as
possible to one another, which weights are mounted on both chains with link
bolts so as to be connected one to another.
The pulley shaft d in order to produce current is periodically rotated by the
action of the weights with an always equal movement when the weights are
moved over the chain pulleys e. On the large cog wheel e a pawl is mounted
which is pressed by a spring against one of the two chain pulleys e and a stop
or projection m is provided on the chain pulley in the path of said pawl to
be engaged thereby. By rotating the cog wheel c the said rotation is transmitted
to the chain pulleys e which are firmly connected with one another, and thereby
a lifting of the weights i takes place periodically as indicated in Figures 6
by an arrow. When the weights pass over the chain pulleys they
cause a further rotation of said pulleys and the shaft by their
gravity, in order to produce the current, Figure 7, and having arrived below
at the bottom pulley h are again raised 'by the engagement of the pawl k on the
stop or projection m of the chain pulley."
On the descent of the weights i as the chain pulleys e would rotate more
rapidly than the cog wheel c, the pawl 7 disengages from the stop or projection m
and when the said rotation of the pulleys is completed it again encounters the
stop. In this manner by the periodic action of the weights, an always equal
rotation of the shaft d is effected.
The cog wheel c might also be firmly mounted on the shaft d and then the
chain pulleys e must be loosely revoluble on said shaft d. The latter could not.
then serve for producing current, but a separate driving connection with the
chain pulleys must be made in order to rotate a shaft serving to produce the
current. This may be easily effected by arranging as shown in dotted lines
in Figure 1 a spur wheel n on the outside of one of the chain pulleys e through
which wheel the rotation would be, transmitted to a spur wheel on the shaft to
be driven, which is not shown in the drawings.
In the form of construction shown in Figures 4 and 5 only a single chain
wheel e need be fixed on the shaft d which is to be evenly operated periodically.
The link bolts are in this case prolonged beyond the pulley e to both sides
in order to carry a weight i on each prolongation. Opposite the catch pawl
which is carried by the spur wheel c there is a disc o carrying the stop or pro-
jection m, said disc o being made in one piece with the hub of the chain wheel e.
Otherwise the arrangement is the same. In this case also the endless chains f
carrying the weights travel over pulleys h lying at a lower depth, Figures 6-8.
The lower pulleys h may also be omitted but in that case care must be taken by
arranging safety devices p over the upper pulleys e that the chains do not come
out of connection with the pulleys e.
Of course the pawl might also be arranged on the chain pulley e or the

page_text: disc o connected therewith, whilst a fixed catch or stop m may be arranged on the
spur wheel G, but this alters nothing in the essential idea of the invention.
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:
1. An apparatus for producing electric current by means of motors driven
by irregular power, comprising a chain pulley or pulleys (e) and endless chain
or chains (f) carrying a weight or weights (i) passing over said pulley or pulleys,
which latter are adapted to be operated from the motor by the engagement of a
catch or pawl () and stop or projection (m) until the weights carried over the
pulley or pulleys drop and effect a longer lasting and always equally maintained
further movement of the pulleys (e), during which movement the pawl and stop
are disengaged, whilst on the completion of the drop the pawl and stop again
come into engagement for the next lifting of the weights, substantially as herein-
before set forth.
2. The improved apparatus for periodically producing electric current by
means of irregular motive power, constructed and operating substantially as
described and illustrated respectively in the different figures of the drawings.
