To- get the concession. Since that day,
however, they have so improved their
SYSTEM, and the exact time furnished
by them has become so useful to the
public, that the Municipality are now
willing TO grant them what they for
. merly asked for, and they have under
taken to do the work ON large scale in
Vienna.
In Paris, too, Since 1873, large.num-
Der Of householders have had the time
transmitted TO their residences by the
pneumatic process, aud numerous pneu-
matte clocks have been put up in the
streets. At first pipes through which
the compressed air could be sent were
laid down in the sewers of the first,
second and ninth ACCOMPLISHMENTS OF
the city. There was, however, no dis
tribution of time to private residences.
Soon, however, company, known as
the C0mpdgEie Generate des H0riOqes
PieUmGtiqUes, was authorized TO per-
form this service, and a year ago last
March it was ready to begin the work.
Six miles Of pipes had been laid down,
and four clocks, which received the
pneumatic time from the central works,
were fixed on lamps ON the boulevards.
These public clocks came to be of great
use. Their time was always correct,
and people got into the habit of regu-
lating their watches by them Subse-
quently the system was further extend
ed, and now there are sixteen miles of
pipes laid down in the sewers, and
1000 pneumatic clocks in 800 houses
are connected with the central works
and are receiving the time from them.
The number of public clocks in the
streets has also been increased to four
teen, with thirty-three dials.
| The system has worked so well and
has proved of SO great public conven-
1 ience that OF late, we are told, the pat
entees have obtained a concession from
| the Prefect of the Seine which will en-
able them to vastly extend their ar.
rangements for distributing the time.
Their plan is TO lay down pipes through
| which they can send compressed air
which will aetuatc all the clocks of
! Paris, ii necessary.
| This is the way in which the time is
! sent: AT the central works there is
/ great clock, which controls the whole
| system. II is a pendulum clock of re-
markable precision and perfection of
mechanism. To il is connected q pc
culiar contrivance. by means of which
valve is opened and shut every minute.
When the valve is opened compressed
air furnished by steam engines working
air-compressing machines is admitted
into the system of pipes, and all the
clocks connected with ii are actuatcd
at the same time. The opening takes
place at the sixtieth second Of each
minute, and the air flows for twenty
seconds, when the valve is closed. This
space of time allowed is the result of
experience, and may be varied accord
ing to the distances through which the
compressed air has TO travel.
1t is not necessary for us to describe
the machinery in detail; nor shall we
attempt to explain the mechanism of
the clocks worked by the pneumatic
system. IL is enough to say that as the
central clock moves so move all those
connected with it. In this way exact
and uniform time is furnished, and
when the Pneumatic Company take adj
vantage of their concession, which gives
them a monopoly OF laying pipes for
fifty years, it win be supplied through
out Paris. The cost, too, is so small
that the people generally will be able
to have it. Thus, the charge for a sim
gle clock is only one cent day, and if
there are more in house the price for
each is much reduced. This price,
however, includes laying the pipes and
| supplying the clock, or, ii desired, fitting
works to existing clocks. Since the
pneumatic system saves the household
er from all care about his clocks and
all expense for their repair il will be
seen that the cost is at least no greater
than that OF maintaining the old time
pieces. BY it, too, he can always be
/ sure that he has the correct time.
The pneumatic clock, therefore, is q
great gain, and is likely to be intro
duced into many cities We are told
that not only Parisand Vienna, but also
ST. Petersburg and Madrid and two
large towns in France, are soon 10 have
time distributed by the system, and
that it is TO be introduced into England.
