COMPLETE SPECIFICATION.
Arrangement for Starting Gas- and Petroleum-engines.
I, ANTON NIEMCZIK of 5 Wiesenstrasse, Leipsic-Eutritzsch, Germany,
Manufacturer, 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 :-
The object of the invention is, an arrangement for starting gas- and petroleum-
engines by means of which the troublesome operation on the fly-wheel for starting
the engine is avoided by using compressed air. With gas-engines the compressed
air is mixed with the gas under pressure.
On the accompanying drawing
Fig. 1 is a vertical section through the part in question of a gas-engine provided
with the present arrangement.
Fig. 2 is a plan of the valve-casing.
Fig. 3 is a vertical section, and
Fig. 4 a horizontal-section of a petroleum-engine adapted with the new
arrangement.
In the gas-engine shewn in Figs. 1 and 2 there is arranged a reservoir a for the
compressed air. The compression of air in this reservoir for future starting of the
engine can be effected either by the engine itself whilst in motion, or by a hand-
pump o.
The air-reservoir a is connected by the pipe a¹ with the lift-valve c in
the valve-casing A; whilst the gas pipe 61 is connected with the lift-valve d. From
the two valves c and d, passages a² and 62 lead through the cock B, or its passages g
and h, to the channel C, which conducts to the compression-chamber D. This
latter is provided with an ignition-pipe e, the heating of which can be effected in
any desirable manner.
In order to set the motor in motion the cock B is opened after the crank has
been brought to its dead-point position, so that compressed air and gas rush into
the compression chamber out of the reservoirs a and b, and after thorough mixture
and collection ignite at the ignition-pipe e. The explosion then follows which
throws the crank forwards and sets the engine in motion so that a regular
movement can now begin. The reservoir a is so large that should the first feeding
with compressed air and gas under pressure not suffice in order to effect the
compression of the charge, the cock B may be repeatedly opened.
If several successive openings of the cock B are to be provided for at the
commencement, this cock can be worked by the engine itself.
The starting-arrangement for petroleum-engines forming the subject of the
present invention is chiefly applied to such engines in which a part of the air is
used for conducting the petroleum gas out of the gas-generator. The reservoir a
shewn in Fig. 3 is filled with compressed air which can be previously compressed for
the next starting either when the engine is in motion or by a separate hand-pump o.
The reservoir a is connected by the pipe a¹ with the cock i which leads to the
compressing-chamber D of the engine. Adjoining the compressing-chamber D
the generator k is arranged in usual manner, and which at the same time serves as
ignition-pipe, and can be heated in any desired way.
If the engine is to be started, the crank is placed in dead-point position, and
5 after the generator k is heated, on the one side petroleum is injected into the
generator k through the injection-channel m, on the other side compressed air
enters through the cock i. It is to be observed that the injection of the petroleum
can be effected either by a petroleum reservoir being already under pressure by a

page_text: former working of the engine, or by using a hand-pump for the purpose. The
compressed air streaming in through the cock i partly rushes over the tongue n
into the gas-generator and forces the petroleum gas out of it, and partly passes the
front of the tongue n directly into the compressing-chamber D in which com-
bustible compound is formed in consequence. This takes light at the generator k,
so that the crank is driven downwards. By this means the engine takes its regular
motion, and the cock i can be closed.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is :
1. Arrangement for starting a gas-engine, consisting of reservoir a for the
compressed air, the hand-pump o for compressing the air, lift-valves c, d and a
shut-off cock B, as described.
2. Arrangement for starting a petroleum-engine, consisting of a reservoir a fitted
with a hand-pump o for the compressed air, of the pipe a¹ and of a shut-off cock i,
as described.
