How il IL to be Done in the Future-.A
German Invention Tor the Purpose. ae Is
From the New York Com. Advertiser, Dec. 70.
| It is we'll known that many endeavors
have been made to light cars In a more
cheerful manner than at present, but
every attempt has failed until the
present time. Lamps with chimneys
could not be used on account of the
draught; coal gas, sufficient for long
journey, required too much space, and
| it was found that when it was com
pressed it deposited carbon and lost all
it's lighting power. Therefore it
seemed that better hope of lighting the
cars must be relinquished until new
and cheap illumination should be found.
Well, an illumination has been found.
which. however, is not exactly new,
but it combines all the requisite ele
ments. The discoverer is Herr Julius
Pintisch, Of Berlin, the famous manu-
facttlrer of gas metres and gas fittings.
and the discovery is oil gas.
The system Herr Pintisch propose to put
in operation is as follows: The
bottom OF each carriage is filled with
reservoir of wrought iron, into which
the gas is forced at a pressure Of ninety
pounds. The gas then flows from this
reservoir through very simple regula-
tor to a lamp which is placed in the
roof OF each carriage in the ordinary
way. The oil-making apparatus con-
sists of q double-story retort, and oil 70
any kind, or fat: in fact, almost any
cheap hydro carbon will do This is
introduced in continuous stream into
the upper retort. Here it becomes par
TALLY volatilized, and then circulating
through the lower retort the process is
complete, and the gas is passed through
a short length of pipe to a purifier,
charged with sawdust and lime, and
thence to gas-holder On the road on
which this gas has been introduced, the
cylindrical portions of two locomotive
boilers, with flat ends riveted in, are
used to hold the gas, which is pumped
by small COMPRISING engine, operat-s
ing not on the gas directly, but on oil,
which rises and falls. The gas is
pumped into these at a pressure of
ninety pounds. The gas is then
pumped into the compressed reservoirs
under the carriage, and long train can
be supplied in eight minutes. The gas
is led to the lamps in the roofs by
small pipes One-fourth inch in bore. A
reflector is placed over each fame, and
through this reflector passes a flat chin
ney. The air for combustion comes
down outside this chimney, finding it's
way through small perforations, and at
the highest speed no Pickering is per-
ceptible. Before the gas reaches the
lamp it is obliged to pass through a
regulator, and this is one of the essen
tial features of the whole design Tt
consists of small iron box, placed
under each carriage, out of the way.
This vessel is divided into two portions
by diaphragm of dressed sheepskin,
which is partially supported by small
leve and spring. The lever acts on
little conical valve, and the moment the
pressure becomes too much for the dia-
phragm it rises and shuts off the gas.
AS regards results, the following will
show: In a receiver, made of wrought
iron of an inch thick, 5 feet 10 inches
long, and l foot Al inches in diameter,
at I'VE atmOSpnereS pressure, sufficient
gas was held to run distance of 1000
miles. It may be imagined that the
gas would waste away or lose its light
ing power during SO long run, but
this is not the case. This point has
been set at rest by Herr Giles, Ger
man railroad man, who filed receiver
and left it untouched for eight months,
at the end of which time it was found
to contain gas under a certain pressure,
and of good Illuminating power. An
experiment of the rudest kind has been
made in England with the discovery,
with the most gratifying results. IF all
that is claimed for this system can be
substantiated, there seems to be no
reason why the railway car of the flu
ture should not be as we'll lighted as a
drawing room. The discoverer claims
that his system will decrease the pres
ent cost Of lighting cars.
