ELECTRIC CURRENT, SWITCHES AND CUT OUTS," a communication to me from abroad
by Charles. G. Perkins of New York United States,
The invention relates to applying in connection with storage batteries a vessel
containing mercury for operating suitable mechanism for changing the current
after the batteries have been charged.
The invention relates to a tube made of glass or other suitable material with a
globular enlargement at one end containing mercury or other suitable material
which supports a globular or flat float provided with a perpendicular extension
having guides integral therewith.
The invention relates to a circuit breaker composed of a plate of insulating
material mounted with a metallic ring having a segment thereof insulated. The
said insulated plate is mounted on a shaft which is provided with a lever having
a globular formation on' the end thereof which engages with a corresponding
depression in an upright spring. The aforesaid shaft is mounted on bearings which
are fastened to a horizontal extension of a metallic standard being the positive
pole of the battery cell. The said horizontal extension is provided with contact
springs which engage with the periphery of the aforesaid metallic ring.
The invention relates to a glass tube with a globular enlargement at one end
and integral therewith and partly filled with mercury and the metallic wires
passing from the exterior to the interior of said tube. The said wires have their
ends bent downward one being longer than the other so that the current will
always break at the same place.
The invention relates to connecting one end of an electrical conductor with the
positive pole of each storage battery coupled in series in the usual way; said
electrical conductors having their other ends electrically connected with metallic
plates insulated from each other by suitable material; said plates come in contact
with a switch spring when moving it over their surfaces.

The invention relates to two parallel metallic plates arranged against a wall or
in any other suitable manner; one of the plates is divided into three parts
separated by a strip of insulating material, the other plate is composed of a series
of plates insulated from each other electrically connected with one of the poles
of the batteries forming a series; said series of plates are slightly concaved on the
inner side thereof.
The upper portion of the side plate composed of a series of plates is connected
with the battery circuit. The lower portion of the side plate composed of the
three plates heretofore mentioned is brought into the circuit of the generator by
means of an electro magnet described hereinafter.
The upper portion of the side plate is at all times in the circuit of the
generator.
•
The invention relates to arranging one or more resistance lamps or other devices
having a high resistance in the circuit of the generator between the electro-
magnet placed in the same circuit thereof and the generator, the object of which
is to enable the electro-magnet to draw down the core slowly until a new and
unobstructed passage is made for the current, the operation of which will have
cut out the resistance lamps and the current will then flow freely to the storage
batteries.
The invention relates to a plunger made of insulating material mounted with
two flat metallic springs, one of which has caeh of its ends turned upward and
slides in a groove made in the side plate with which it engages; said spring is
electrically connected with the negative wire of the generator.
The second flat spring has its upper end turned upward and it also slides in a
grooove, the lower portion of this spring is provided with a metallic roller
electrically connected therewith and engages with the aforesaid series of metallic
plates electrically connected with the batteries.
The plunger heretofore mentioned is connected with a core of an electro magnet
of the solenoid type by means of a rod.
The upper part of the plunger is connected with one end of a retracting spring,
the other end of the spring is connected with an adjusting screw. I do not wish
to confine myself to a retracting spring for holding the plunger in its normal
position, as I am aware that weights may be connected therewith instead of the
spring without departing from the spirit of the invention.
The invention relates to arranging a series of storage batteries in the main
circuit of a dynamo electric machine and arranging an electro-magnet of low
resistance in said electrical circuit between the dynamo electric machine and the
storage batteries; said magnet operating, a circuit closing and breaking device
mechanically connected with a switch or cut out placed in the circuit between
the batteries and lamps.
The invention relates to arranging a high resistance magnet in the derived
circuit between the low resistance magnet and the dynamo electric machine; said
high resistance magnet operating the core of the former so as to bring the
low re-istance magnet into the main circuit of the dynamo electric machine.
The invention relates to an electro magnet of the solenoid type having its core
connected with levers rigidly fixed to a shaft supported by bearings diametrically
opposite each other; said shaft carrying an insulated disc mounted with two
metallic plates on the periphery thereof, one of the plates being shorter than the
other and two upright springs bearing against the periphery of said metallic
plates; said springs are in the main circuit of the generator when they are both
in contact with one and the same metallic plate.
The invention relates to a cut out switch mounted on a base of insulating
material provided with metallic plates insulated from each other; each of which
are separately electrically connected with a positive pole of the batteries; the
aforesaid switch is mechanically connected with levers, one of which is rigidly
fixed to the shaft carrying the insulated dise heretofore mentioned.
The invention relates to an electro magnet of high resistance, electrically

page_text: connected with the shorter metallic plate of the insulated disc heretofore
mentioned; by means of one of the aforesaid upright springs said plate is
electrically connected with the positive wire between the circuit closer and
generator by means of a horizontal spring, which is in constant contact with the
short or metallic plate mentioned above, and is in the derived circuit when the
generator is first started, the negative end of the wire is eletrically connected
with the negative wire of the generator.
The invention relates to connecting the lower end of the core of the low
resistance magnet, with the core of the high resistance magnet by a rod; said
magnets are arranged on the same perpendicular alignment; both cores are.
suspended by a retracting spring connected with an adjusting screw supported by
a frame resting on the top of the low resistance magnet; the frame is provided
with an adjustable screw on the side thereof, which regulates the throw of the
levers connected with the core of the low resistance magnet.
