A LAW TO DETERMINE THE
RIGHTS OF THOSE WHO ARE
NOW IN THE BUSINESS
1t Covers Ground Already Taken BY
Westinghouse and Others and
Will Lead TO Endless Litiga-
ton and Sure to Compel
Larger Payments.

New York, December pa speclal
to the Herald from Washington says:
The patent office has granted three
important patents to Rudolph NJ
Hunter, of Philadelphia, assignor to
the General Electric company of New
York, on the transmission of electrical
energy, covering a period Of seventeen
years. Should the Supreme court OF
the United States uphold these pat
ents, millions of dollars in royalties
must be paid by the Westinghouse
and other electrical companies.
These patents are of greater impor-
lance to the electrical world than any
granted in years, as the appliances
covered by the patents are being used
by the large electric lighting concerns
in all the large cities.
Mr.. Greedy, assistant commissioner
of patents, said:
The patents cover briefly the idea
of generating high tension currents
and transmitting them through a wire
or by means of Induction coil, or
transmitters, into low tension current
or high tensoned currents, as the
case may be, for distribution. BY
|
and the currents can be sent a great
er distance There is far more dam
| ger in these currents, as they are too
| high tensioIed to be used in lighting
or for power purposes. The system
| patented however, enables the cleo
| trio company to transmit heavy cur
rents into low tension by sending the
| high tension through fine wire coil

| wire wound round ii. The nigh ten
sion current generates by indueting a
current of lower tension in a coil of
courser wire. BY this process one
current can be regulated at will.
| There is no doubt that the patents
| cover systems which are very largely
in use at the present time They are
very broad. They will probably more
| largely effect the Westinghouse COM
pany than any other electrical concern
in this country and in all probability
will result in long drawn out law
| suits.
"They will not effect the electrical
roads because they use what is known
as the direct current. These patents
have reference to what is known as
the alternating current. 1t is large
| u
l think, for power purposes.
| "Of course, the general electric COM
| pany will be entitled to royalties
| wherever this system is in use. and ii
| will be impossible even to estimate
the amount of money involved in this
particular case. 1t will certainly run
up into the millions, and almost GER
tainly result in long drawn out law
suits"
The more important claims set forth
by Mr.. Hunter in his applications are:
Claim = A line conductor, convey
ing high tension currents of alternate
1y rising and falling potential, a vari-
ebble resistance in the line circuit: an
indication coil, having its fine wire i'm
circuit with the line; local circuit in
Guiding the coarse wire of the induc-
ton coil; and a translating device i'm
said local circuit, consisting of an ell
ectro magnet to vary said variable re-
| sistence.
| Claim The Improvements in the
art of transmitting electrical energy
| to and utilizing it at distance from
| the source, which consists in geherat-
| ing maintained and practically uni
| form alternating currents of high ten
sion and sending the same over a line
Of conductors to another station. and
generating maintained practically
uniform alternating currents of lower
tension at the second station by the in
ductive influence of the high tension
! currents
Claim 5 The method of transmit
| ting electrical energy, consisting in
transmitting and electrical current OF
high tension and small volume over n
line circuit and one or more places ON
the line circuit, producing by means OF
induction maintained and practically
uniform currents of low tension and
relatively large volume, and supply
ing said low tension currents to one OF
more translating devices in said local
| circuits.
Claim 13 The combination of an
interrupted electrical current of high
tension, line of primary circuit. the
high resisting coil in circuit with said
line current, low resistance coil nara
lell and in close proximity to tho
high resistance coil; local or Sec
ondary circuit, including said low re-
sistence coil, and frame of magneto,.
material in close proximity. upon
which the coils are wound.
