Improvements in Smoke Conducting Apparatus and Spark Arresters
for Locomotives and the like.
I, KONRAD KNOBLOCH of No. 1 Grosse Schiessgasse Dresden in the Empire of
Germany Physician, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in smoke conducting apparatus and
spark arresters for locomotives and the like. The object of which is to obviate
a very disagreeable molestation and anti-hygeian danger or risk to the passengers
and engine driver or the travelling public generally which results from the
emission of smoke from the engine chimney during the journey touching upon all
the carriages, cars, or waggons of the train.
All smoke consumers used hitherto have not been generally applied to
locomotives, or provided on engines by this invention the smoke is derivated or
conducted in a suitable, effective and more inexpensive manner at the same time
arresting the sparks emitted from the funuel of the locomotive and the like.
The contrivances consist of a horizontal chimney which extends longitudinally
from the funnel or chimney of the locomotive engine along the roofs of the cars or
waggons to the rear extremity of the train.
Each car or waggon whether of a passenger or freight train is provided with
a section or part of the longitudinal pipe, which has a conical or truncated and
a tubulated enlarged extremity each pipe being of such a length that both ends
project over the buffers of the car or waggon. The diameter of the same is
preferably somewhat larger than the smallest diameter of the vertical funnel of
the locomotive engine.
The said pipes may be made fast to the roof of the cars or waggons in any
convenient manner, and contrivances may be also provided for the dilation of
the pipes.
In making up a train the pipes are so arranged that the enlarged extremities
of the same are directed towards the engine. The truncated extremity of the
first one then enters the enlarged extremity of the second one, and so on until
the whole train of waggons are made up. The locomotive engine carries a fixed
horizontal pipe the rear extremity of which enters the enlarged end of the pipe
over the tender or tank, the fore extremity of the first pipe is connected and
opens into the mouth of the funnel or chimney of the locomotive its front end
is tubularly enlarged and is internally provided with a derivating or deflecting
partition extending partly over the vertical funnel or chimney and thus preventing
any down pressure of the air current entering the mouth of the horizontal pipe
and the ingress of rain or snow into the vertical funnel or chimney.
Above the vertical engine chimney is provided a valve or lid which is generally
during the journey kept closed by a weight or spring, it may however be opened
for the outlet of the smoke immediately after firing, or when the engine stops for
some time, or when a stiff wind blows in the same direction as the train is going,
and the velocity of the wind is equal to that of the train.
For this purpose the valve or lid is provided with a cord or wire rope, chain or
the like which may be operated and adjusted by the engine driver. It will be
observed that the air entering the mouth of the horizontal pipe draws or sucks up
from the vertical funnel or engine chimney the smoke into the said pipe. At the
tubulated or enlarged extremities of the several pipes the external air is also sucked
in and accelerates the velocity of the air current in the chimney so that it is not
necessary to operate the blast pipe and the steam may be used for other purposes.

page_text: But
In consideration of the length of the whole pipe and owing to the cooling effect of
the same I may assume that very few sparks will be emitted with the smoke.
if however the smoke should contain sparks the rear extremity of the last horizontal
pipe may be provided with a spark arrester the body of which may be bottle or
balloon shaped having an opening closed by a sieve, which opening is over roofed
by a curved shed or screen, the said appliance may be attached to the rear
extremity of the last horizontal pipe in any convenient manner.

COMPLETE SPECIFICATION.
Improvements in Smoke Conducting Apparatus and Spark Arresters
for Locomotives and the like.
I, KONRAD KNOBLOCII of No. 1 Grosse Schiessgasse Dresden Old City in the
Kingdom of Saxony Empire of Germany Physician, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention relates to improvements in smoke derivating and conducting
apparatus and spark arresters for locomotives and the like. The object of which
is to obviate a very disagreeable molestation, and anti-hygeian danger or risk to
the passengers and engine driver or the travelling public generally, which results
from the emission of smoke from the engine chimney during the journey touching
upon all the carriages, cars or waggons of the train.
All smoke consumers used hitherto have not been generally applied to
locomotives or provided on engines.
By this invention the smoke is derivated or conducted in a suitable effective and
less expensive manner, at the same time arresting the sparks emitted from the
funnel of the locomotive.
These objects are attained by aid of the apparatus illustrated in the accom-
panying sheet of drawings.
The contrivances consist of a horizontal chimney which extends longitudinally
from the funnel or chimney of the locomotive to the rear extremity of the
train.
Each car or waggon, whether of a passenger or freight train is provided with a
section or part of the longitudinal pipe a, which has a conical or truncated and
a tubulated enlarged extremity, each pipe being of such a length that both ends
project over the buffers of the car or waggon. The diameter of the same is
preferably somewhat larger than the smallest diameter of the vertical funnels of
the locomotive engine.
The said pipes may be made fast to the roof of the cars or waggons in any
convenient manner and contrivances may be also provided for the dilation of
the pipes.
In making up a train the pipes are arranged so that the enlarged extremities of
the same are directed towards the engine. The truncated extremity of the first
one then enters the enlarged extremity of the second one, and so on until the whole
train of waggons are made up. The locomotive engine carries a fixed horizontal
pipe, the rear extremity of which enters the enlarged end of the pipe over the
tender or tank, the fore extremity of the first pipe is connected to and opens into
the mouth of the funnel or chimney of the locomotive, its front end is tubularly
enlarged and is internally provided with a derivating or deflecting partition
extending partly over the vertical funnel or chimney c, and thus preventing any
down pressure of the air current entering the mouth o of the horizontal pipe, and
the ingress of rain or snow into the vertical funnel or chimney c. Above the
vertical engine chimney is provided a valve or lid d which is generally, during the

page_text: journey, kept closed by a weight or spring. It may, however be opened for
the outlet of the smoke immediately after firing or when the engine stops for some
time, or when a stiff wind blows in the same direction as the train is running, and
the velocity of the wind is equal to that of the train.
For this purpose the valve or lid d is provided with a cord, wire rope, chain or
the like, e, which may be operated and adjusted by the engine driver. It will be
observed that the air, entering the mouth of the horizontal pipe, draws or sucks up
from the vertical funnel or engine chimney the smoke into the said pipe. At the
tubulated or enlarged extremities of the several pipes the external air is also
sucked in and accelerates the velocity of the air current in the chimney, so that it
is not necessary to operate the blast pipe and the steam may be used for other
purposes.
In consideration of the length of the whole pipe, and owing to the cooling office
of the same, I may assume that very few sparks will be emitted with smoke, but if
however the smoke should contain sparks the rear extremity of the last horizontal
pipe may be provided with a spark arrester F, the body of which may be bottle or
balloon shaped having an aperture f, closed by a sieve, which aperture is over
roofed by a curved shed or screen g, the said appliance may be attached to the rear
extremity of the last horizontal pipe in any convenient manner.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The combination of a train with a horizontal chimney extending longitudinally
from the funnel of the locomotive engine along the roofs of the cars to the rear
extremity of the train, said horizontal chimney consisting of sections with a
truncated and an enlarged extremity, all substantially as set forth and for the
purpose specified.
י
2. The combination of the horizontal chimney such as above described with a
spark arrester of a bottle or balloon like shape, having an opening closed by a
sieve, which opening is over roofed by a curved shed or screen, all substantially as
described.
