Storage Plant.
Hon. James Campbell has MS
beautiful residence at kNpioiani
Park thoroughly lighted with cleo
tricity from a storage plant. Some
months ago he imported the most
complete apparatus obtainable for
the purpose from leading manufac-
turers in the Eastern States. An
expert electricians services were
rendered him to set up the elaborate
mechanism, but he preferred to have
the work done by one living here,
who would be on hand TO rectify
anything going wrong after starting,
Mr.. john Cassidy, Superintendent
of the Bell Telephone Company,
who has always made a study of
electrical science beyond what he
required for the telephone business,
was Mr., Campbell's choice for the
important business, The confidence
in Mr.. Cassidy's skill thus shown
has been justified by the most UNI
qualified success Of the system.
Mr.. Campbelrs plant consists Of
four horse power dynamo, from
the Eleotro-Dynamic Co. of Phila-
delphia n battery Of thirty-three
accumulators, froiB the Electrical
Accumulator Co. of New York a
switchboard furnished with REQ
stadt regulator, for regulating the
dynamo and preventing its heating;
an English eight horse power porta-
ble engine, and conductors to all
parts of the house. Each accumu-
lator or cell contains fifteen lead
plates-seven positive and eight ne
gative--in a solution of sulphuric
acid. The storage battery when
fully charged has capacity of fifty
two incandescent lights for six
nights at six hours per night, BY
running the dynamo while the bat
terry is diseharging its electricity in
light, the capacity is doubled or
over one hundred lights supplied for
the period mentioned. Mr., Camp
bell has forty lights in and about
the house; the verandas, bedrooms,
| kitchen, closets, etc., being all sup
piled with lamps, as we'll as three
iive-light crystal chandeliers to illu-
inmate the parlors and dining room.
On Tuesday evening" by invita-
tion of Mr, Campbell, q small party
comprising Hon. A. Young and Mr.
y. Hedemann of the Honolulu Iron
Works, Miss Young, Hons. Cecil
and Frank Brown, Mr.. H. Mcintosh
and a BULLETIN representative, wit
messed an exhibition of the system
by Mr.. Cassidy at the residence.
Mr.. and Mrs. Campbell were pre-
sent. Everything worked like a
charm and the observers were
thoroughly convinced that the
storage system satisfactorily solves
the problem Of house lighting, The
whole house was brilliantly illumi-
mated with soft, steady light, the
turning of button setting either a
whole chandelier or single lamp
lglow at will, while the engine and
dynamo were not running, or need
ing 30 run with the score of lights
connected for a fortnight. This
was lighting wholly from the stored
| supply of electricity. An exhibition
vas given, also, OF lighting directly
from the dynamo, in which a slight
luivering Of the rays was noticeable
corresponding to the puIsations Of
the engine.
Mr., Cassidy showed the party the
very elaborate wiring connection:
in the attic, which displayed grear
deal OF very patient work, the con
! ductors being run through the pipes
Of the discarded gasoline system
down TO the chandeliers. There are
safety blocks in every separate con
ductor, whereby an excessive cur
rent cuts itself off by the fusion o
soft metallic bar. 1t was amusing
to see the electrician moving abou
under the rafters, lighting up th'
dark recesses with an electric laml
he carried at the end of coil o
string. With this he is able 10 in
spect any part Of the connection
between walls or elsewhere unsaf
for the introduction Of any othe
light There are automatic device
in the storing apparatus for regulat
ing the current so as to preyen
oyercharging and give indication o
exhaustion of the battery whicl
would be injurious. The dynamo
switchboard, etc., are highly finished
and beautiful pieces of mechanism
| Mr.. Campbell is delighted viii
the complete success OF the system
1t gives him abundance of ligh
without danger of interruption
from accident to the motive powe
or the storage battery coming singly
If the engine breaks down th
charged battery will furnish ligh
until it is repaired, while if the bat
tery's supply is interfered with th
lighting can be done direct from tht
dynamo. The plant can be removed
in few hours and attached TO light
ing connections ia the owners towr
residence. bir. Cassidy is to b,
congratulated on the great success
