Improvements in and relating to System of Electric Distribution.
I, MORRIS FEILBOGEN, a Citizen of the United States of America, residing at
No. 137 Broad Street, in the City, County and State of New York, one of the
United States of America, Gentleman, 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 an improved system of electric distribution, and it has
for its objects to provide for interrupting the current of a constant electric
generator or dynamo, so as to give the proper impulses to an inductorium, or
series of such devices, to generate a secondary current, or a series of secondary
currents to be employed in an electric light or working circuit, or a series of such
circuits.
And the invention further has for its object to provide for automatically
regulating the intensity of the current in the main circuit of a system of electric
distribution, as more fully hereinafter specified.
The above-mentioned objects 1 attain by the means illustrated in the accompany-
ing drawings, in which-
Figure represents a diagram showing the parts of my invention and proper
electrical connections.
Figure 2 represents a side elevation of the disrupter or circuit breaker, forming
a part of my invention, and
Figure 3 is a top or plan view of the same.
Referring to the drawings, the numeral, 1, indicates a dynamo electric generator
of that class in which a constant current is generated. To the shaft of said
generator is secured the usual commutator, 2, against which the brushes, 3, bear, to
convey the current from the generator.
The numeral 4 indicates the disrupter or circuit breaker. This consists of a
disc of insulating material, having a series of equidistant recesses in which are set,
radially, segmental blocks of conducting material, 5, the outer surfaces of which
are flush with and form a continuation of the arc of the circle of the periphery of
the disc. The said blocks or segments are in metallic connection with a disc, 6,
which is in metallic connection with the metallic shaft carrying the disrupter or
circuit breaking disc.
The numeral, 7, indicates a brush, which is secured to a support of insulating
material mounted upon the frame of the disrupter at one side thereof. The said
brush is provided with a binding post, 8, to which one of the terminals, 9, of the
main circuits of the generator is connected. The disrupter frame is also provided
with a binding post, 10, which may be connected with the other terminal of the
main circuit of the system.
The numeral, 11, indicates a coil in the interior space of which is set a core of
soft iron, 12. The said core is attached at its upper end to a lever, 13, fulcrumed
at 14 to a bracket, 15, secured to the upper part of the coil spool. The said lever
at one end is curved and caused to bear upon the periphery of the disc of the
disrupter or circuit breaker and at the other end is provided with a weight, 16, by
which said lever is held normally against said disk. Instead of a weight, a
spring, 17, may be employed for the purpose. The coil when in use is in electrical
connection with the main circuit of the dynamo, and by its action on the core gives
a variable pressure to the brake lever, so as to regulate automatically, the movement
of the disrupter disc.
The variable pressure of the brake lever upon the disc of the disrupter will

page_text: permit the disrupter disc to travel at a variable speed, and thus regulate the
rapidity of the impulses of the circuit.
Any number of circuit breakers may be employed in connection with the
system, three being shown in the present instance.
The shaft of each disrupter is provided with a pulley, 30, and each pulley is
connected by means of a belt, 18, with a friction pulley, 40, which receives its
motion from the motor which drives the dynamo or generator by the fast
pulley, 45.
The numeral 20 indicates a condenser of the usual construction, which is con-
nected in shunt with the brush and the binding post, and which may be placed in
the main circuit or cut out therefrom as may be desired.
The numeral 22 indicates a series of coils, the cores of which are each secured to
one end of the soft iron bars, 29, and to the opposite ends of the said bars are
secured the cores of similar coils, 23. The coils, 22, constitute the primary coils
of a series of induction coils which are connected in the main circuit with the
disrupter or circuit breakers, and the coils, 23, constituting the secondary circuit
are connected with the binding posts of a switch board, 90, of the ordinary
construction, the bars, 60 and 70 of which may be connected by means of removable
pins, 50, so as to connect the secondary circuit or circuits in series, or in multiple
arc circuits, as desired.
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 a system of electric distribution, the combination with a constant electric
generator and an inductorium or a series of the same, of a series of circuit breakers
having their brushes connected with the primary coils of the inductoriums, a series
of brake levers by which the circuit breakers are regulated, a driving shaft having
a pulley connected with the motor by which the dynamo is driven, and a series of
pulleys connected with the pulleys of the disrupters or circuit breakers, as and for
the purpose specified.
2. In a circuit breaker or disrupter, the combination of a disc carrying a series
of conducting segments, in electrical connection with its shaft, and a brush secured
to an insulated seat and adapted to be placed in connection with the main circuit of
the generator, substantially as specified.
3. In a circuit breaker or disrupter, the combination of a disc constructed of
insulating material carrying a series of segments in electrical connection with its
shaft, a brush secured to an insulated support, a weighted brake lever having a
curved spring plate bearing against the periphery of the disc, a hollow coil having
its terminals in the main circuit, and a movable core secured to the brake lever and
setting in the coil, whereby the lever is operated as a brake to control the movement
of the disrupter, substantially as specified.
4. In a circuit breaker or disrupter the combination of a disc carrying a series of
conducting segments and a condenser connected in shunt with said segments,
substantially as specified.
