How Electric Clocks Work,

How Electric Clocks Work,
The principle OF the electric clock is
very simple. y standard electric reg
ulator is placed in the hall OF a pri
waite house, or in the chief offices OF
works. This regulator works by it's
own action for, say, o9ia seconds,
when electric contact is made, and
magnetic pull is exerted, and during
the remaining half second required to
complete the round OF the minute
wheel an ingenious contact arrange
ment lifts a small hall, and momentar-
lily breaks the circuit. so that the
wheel becomes free again. Then, by
the aid and momentum OF the pendu-
lum, the motion is continued, and the
automatic electric action goes on per-
netually day after day, year after
year, for one, three or five years, ac-
cording to the battery power supplied.
The regulators are made to regulate 10,
20 or 30 secondary clocks connectedin
series. These clocks can, OF course, be
fitted III various parts OF the house,
buildings, works on railway stations.
as the case may be, and can thus be
successfully driven by four to six
volts OF intermittent current within
q radious OF two or three miles. The
secondary clocks, being in sympathetic
action with the main circuit clock,
electrically regulated every minute,
and it is claimed that by new method
OF regulation, no clock can deviate
from another OF the same series for
more than one second under any con-
ditions whatever. The municipality
OF Vienna has 600 clocks, regulated
from our main centers. so that stand
ard time is assured in all parts OF the
city. The progress of the new system
CT horology bids fair to make it one
OF the important inventions OF the
age.-World's Progress.
Stoves for Heating and Lighting.
4 French chemist, who has been
giving considerable attention to the
problem OF heating and lighting from
a single source, has devised a novel
stove, which in appearance resembles
an ordinary heating stove. 1t is SO
arranged internally that the waste
heat is utilized for the generation of
electricity. This is secured by a num-
Der OF rectangular boxes Of sheet iron,
containing the necessary metallic ele-
ments for furnishing the current.
These clements are insula ted by as
bestos, and the cooling is effected
partly by the shape in which the me-
tallic alloys are cast and partly
by IL circulation OF air.
The current obtained is not in great
amounts, but the result OF this at
tempt seems to be favorable. Ac-
cumnlators are used for storing up
the electricity, and as the heating is
required for a much longer period
than for lighting the electrical energy,
which would he lost during the hours
OF daylight, IS saved. A point OF con-
siderable moment is that the heat,
so that any portin that can be re-
covered in the form OF electricity is SO
much gain.-Philadelphia Record.
Counting Coins by Electricity.
In the London Mint, it is stated in
the masters report Just published. 81
new counting machine for telling
bronze coin has been erected in the
bronze store The machine has four
distinct sets OF counting apparatus,
each OF which can be worked indie
pendently OF the others, and when all
four are in iuil work, upward OF 5000
pence can be counted per minute. The
coin to he told is raised to the level OF
two tables placed on a platform by a
lift worked by an electric motor,
which also drives the counting ma
chimes. A pair OF these machines is
fed from each OF the tables, the coins
passing from the table down all in
clined iron plate forming flat hop
per, from which they issue in single
file through channel OF appropriate
width. They are then gripped by a
pair OF Indian rubber driving wheels,
which force the coins past the rim OF a
thin disk provided with recesses in its
circumference to fit the circular edges
OF the coins. AS the disk is thus made
to revolve, the coins are pushed for
y ward. falling into a bag placed to re-
receive them, and continue to adj
vance until the counting wheel is au-
tomatically stopped and the bag con-
tanning the coins is removed.
