Evening capital. (Annapolis, Md.) 1884-1910, 1891-07-18

Three war vessels for Chill. now being
built in France are to be fitted with cleo
trio motors for elevating and depressing
the heavy guns; the motors viii be driven
from the electric light circuit.
At the quaint old church in the
grounds of Twyford Abbey, near Ealing,
the remains of lady were inferred in
the family vault, which was brilliantly
Illuminated with incandescent lamps.
This is supposed to be the first funeral by
electric light.
The power of an electric tramway from
Pazyala to Lugano is supplied by
waterfall, the water being conveyed in
two iron pipes to the generating station,
where two turbines of 800 horse power
each drive l 800 light dynamo and a 90
horse power generator.
The committee on light of the board of
legislation of the city of Cincinnati have
considered the matter of lighting Cincin-
natl with electricity, and an ordinance
for that purpose is about as good as
passed. There will be no monopoly. The
present price of $14 per lamp charged
by the Cincinnati Gaslight and Coke
Company will now probably be greatly
lowered. 1t is claimed lamps can be fur
nished at about $50 per year, as is done in
smaller towns. The Edison people count
upon being successful bidder against
the gas company. There will be a bitter
fight, however, before the contract is
awarded.
The directors of the South Stafford
shire Tramway Company, writes the Lon
don correspondent of the Electrical En-
gineer, have issued pamphlet in which
are set forth from various points of view
the advantages of various traction over
steam traction for tramway purposes.
After stating that there are many con-
siderations which make for the final and
complete superseding of the latter method
by the former, and that the authorities
both of Glasgow and Leeds have extern
sive schemes in hand, the directors add
that they have seriously considered the
objections raised by the local authorities
to the use of steam, and after carefully
investigating the various other methods
OF traction they are prepared to recon-
head system of electric traction.
AT the Black Diamond mines in Wash.
ington State, says the Electrical World,
an electric hosting machine has been
placed at the top of a slope 450 feet in
length for the purpose of hoisting coal,
the top of the slope being 3 100 feet from
the mouth of the mine. The generator
which supplies electricity to the motor
attached to the hoist has a capacity of
100 horse power, and is located at the
mouth of the mine, while the motor is
capable of exerting so horse power when
needed. Recently on test IL, 900 pounds
of coal were hoisted at one trip up the
slope in one and one-half minutes. The
plant was manufactured and installed by
the Electrical Engineering Company of
San Francisco, under the supervision of
Professor Keith, the inventor, and is pro-
nounced a thorough success. 1t is claimed
that it makes practicable the working of
many coal and other mines, which could
not be so cheaply AID effectively worked
by the usual methods of steam or pneu.
matte transmission of power.
An electric power hammer has been
devised, says an English exchange which
represents a radically new application of
electro magnetic principles. The novelty
of the apparatus lies in the substitution
of electro magnetic power Of steam by a
slight and very simple modification of
the mechanism. The piston is of mag.
netic material, and the cy yIinder is com
posed of series of coils, through each
of which an electric current may be
passed separately. The apparatus is vir-
tlIally an immense electro magnet. the
cylinder being the coil and the piston
answering to the core. The passage OF
an electric current through the coils form
ing the upper part of the cylinder raises
the piston into the magnetic field thus
created. BY cutting off the current and
simultaneously transferring it to the
lower coils of the cylinder, the piston is
released, and its descent is accelerated by
the magnetic attraction created below.
As magnetic field can be created In
any of the series of coils, the blow may
be shortened or heightened as desired.
