Improvements in and Apparatus for Producing and Utilizing Electric
Currents.
I, BERNHARD SCHEITHAUER, of No. 5 Niemeyerstrasse, Halle-on-the-Saale.
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 refers to apparatus in which two induction coils by means of an
automatic contact breaker and maker alternately come into action, and both
induction coils are connected with two separate secondary batteries in such a
manner that one battery current gives the primary current to one induction coil,
whilst the other battery is charged by a portion of the induction current produced
in such manner and vice versa. The superfluous portion of this induction current
serves for the maintenance of the circuit service.
In the accompanying drawing such an apparatus is shown diagrammatically at
Figure 1.
I and I are the secondary batteries, A A', B B is the automatic contact
breaking and making device, and M M M and N N N are the induction coils.
Each of the latter consists of a closed ring of soft iron M and N respectively, of
which the one half is provided with the primary coil M" and No respectively, and
the. other half with the secondary coil M' and N respectively. These coils
are separated from each other at ox by vulcanized rubber or other' insulating
material.
The contact breaker consists of two corresponding electro magnets A A' and B'B',
between the poles a, b, a¹¹ of which the armature mm, mounted upon the
revolvable or rock shaft W*, is placed. The shaft W* of the armature carries
above as well as underneath the armature m² m², a current closing ring each of
which consists of two half rings insulated from each other and from the shaft W.,
see Figures 2 and 3. Each half ring has an attachment ce and f, respectively.
The attachments e and are in connection with the battery II with the + attach-
ment and the attachment W respectively, and the attachments e and on the
other hand with attachments of the battery 1. Upon both current closing
rings slides a spring d and y respectively, of which is connected at with the
electro magnetic coil A', with the electro magnetic coil 13, with the primary
coil No of the induction coil N at k and with the primary coil M° of the induction
coil M at i. From the attachment g' of the current closing spring a conductor
leads to the attachment of the service circuit. This attachment is also
connected with the secondary coil M¹ of the induction coil M at, whilst the
attachment y of the service circuit is connected by a conductor, first with the
+attachment of the battery II, secondly with the secondary coil N of the induction
The other
coil N at m, and thirdly with the + attachment of the battery I.
ends n and y of the secondary coil of both induction coils are connected with each
other by a wire, and the ends o and p of the primary coils of the induction coils
by a wire with the + attachment of the battery I and with the attachment W
of the battery II respectively. Lastly each spool A and B of the current breaker
is in connection as well with the attachment W of the battery II as also with
the attachment Z' of the battery I.
The mode of action of the apparatus is as follows:-
•
"The shaft of the armature m¹ m¹ is so revolved that the spring d⭑rests on
the half ring c, and the spring g rests upon the half ring f. "The "current of the
battery II then passes from to c d and divides at d' into three paths, of which

page_text: =
the first goes through the spools A' A, returning from the spool A to the clamp w
of the battery II the second also passes through the spools B B to the clamp w,
but the third at enters in the primary coil M° of the induction coil M, flows
through this coil and passing out at p returns to the clamp to of the battery II.
The current excited in the secondary coil M¹ of the induction coil M passes
through the current service circuity, and the unused portion of this current
goes from the clampy through the clamp in the battery I, charging this. The
portion of this charging current passing out of the clamp of the battery returns
back over g, g', to . During this operation the currents flowing through
the spools A A and B B have so magnetized the poles a a, b, that the
armature m² m² oscillates and produces a closure of the current between half ring e
and spring d, as well as between half ring and spring g, but interrupts the current
closure cd and fg. At this instant the current of the battery I flows from
clamp to edd and from thence partly through the spools A A B B-partly
back through the primary coil & Noo of the induction coil N towards the clamp .
The current excited upon the closing of the primary coil N° in the secondary
coil N is united with the current which ensues upon the opening of the primary
current circuit Mº in the secondary coil M', and passes through into the
coil N¹, and the induction current so strengthened flows through the service current
circuit y
The unused portion of this current goes from a through gh to the
clamp w of the battery II, charging the latter. The superfluous portion of this
charging current returns back from clamp of the battery II to y.
In the meantime the armature m¹ m² in consequence of the change of pole of
the electro magnets of the current maker and breaker has again so moved round
that current closure is effected between c d and fg, but the current closure between
ed and gis interrupted. The operation first described becomes again repeated,
only with the difference that the closure current excited in the secondary coil Mi
united with the opening current of the secondary coil N¹, passes through the service
current circuit a y.
The collecting batteries I and II are charged before the commencement of the
working, and the consumed current is during the working for the most part again
replaced, so that the apparatus can be continued for a very long time in action,
before the charging of the secondary batterics from an outward source becomes
.. necessary.
For the purpose of increasing the action, condensators are introduced between
...the collecting batteries and current breaker, and the secondary coil of the induction
coil connected with Leyden jar batteries.
.·
With regard to the decreasing of the effect of the Foucault current, each
apparatus may be constructed as shewn in Fig. 4, where the dotted radial lines
denote the primary coil and the drawn out lines the secondary coil. The Foucault
current will be quite harmless if the iron ring of the apparatus is as many times
bored through as there are windings, and if in these bore-holes metal wires are
firmly soldered, which after leading to the centre point of the ring rest there, as is
shewn in dotted lines in Fig. 4.
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 producing and utilizing electric currents, the combination with apparatus
in which two induction coils M M M' and N N° N', by means of a contact
breaker and maker, alternately come into action, of the connection of both induction
coils with two separate secondary batteries I and II, in such manner that the one
battery current goes to the primary coil of the one induction coil, whilst the other
battery is charged by a portion of the induction current generated, and vice versa,
all arranged and acting substantially as and for the purposes herein set forth.
2. The general arrangement and combination of devices and apparatus, comprising

all acting substantially as and for the purposes herein described with reference to
the accompanying drawing together with any mere modification or modifications
thereof.
