I JACOB FABER of Elberfeld in the Kingdom of Prussia, German Empire,
Engineer do hereby declare the nature of this invention to be as follows :-
These improvements relate to gas-motors with great speed of rotation. They
consist firstly in the starting contrivance for the gas-motors; by means of this
starting contrivance the motors are set in motion in the simplest manner imaginable.
These improvements consist further in the arrangement and employment of several
power-developing cylinders, which operate successively and have one common,
rotating slide-valve, which serves as gas-regulator and distributer. Thirdly they
consist in the using of a mixing-space for gas and air, in connection with a
compressing-space. The common crank-shaft for the cylinders has its bearings in
the mixing-space for gas and air, which likewise contains a pump for feeding the
compressing-vessel. Fourthly these improvements consist in the combination of
several cylinders, which operate successively and have a common, rotating ignition-
and outlet-slide for the exploded gases. These improvements consist finally in the
arrangement of a regulator-valve, which is fitted between the gas mixing-space and
the compressing-space, and serves to regulate the effect of the compressing-pump.
These improvements are represented in Figs. 1 to 19 of the accompanying
drawing.

page_text: Fig. 13 shows in cross section the arrangement of the delivery and suction-valve in
the pump-cylinder.
Figs. 14, 15 and 16 show in three positions the way, in which the rotating ignition-
slide-valve acts.
Figs. 17, 18 and 19 show in longitudinal section the arrangement of a gas-motor,
working with one, two and three power-developing cylinders.
The arrangement of the engine represented in Figs. 1 to 9 and 13 and the way in
which it works is as follows:
a, b, c are three cylinders open on the inside; their pistons i, k, I are driven by the
common crank shaft m and by means of the connecting-rods op g. The crank-
shaft m has its bearings in the hollow vessel n formed by the frame of the engine.
This hollow vessel n is the space for mixing the gas and atmospheric air, that operate
in the cylinders. The pump-piston d¹ which is connected with the shaft m by means
of the rod el is likewise contained in this hollow vessel and works in it.
During the down-stroke of the piston d¹, the gas contained underneath the latter is
compressed and forced through the channel h¹ (Fig. 13) to the delivery-valve f, and
from there through the channel, into the pressure vessel g. During the down-
stroke, the piston sucks up another charge of gas and air through the channel fi
(Fig. 2) into the space n. The gas and air are sucked up together by the lifting of
the combined valve e; the air rushes to the valve e through the pipe o, whereas the
gas streams to it through the inner pipe of, which is in direct connection with the
main-gas-pipe. When the piston rises (Fig. 13), the mixture of gas and air in
the space n passes through the suction-valve g³ and the channel g¹ into the space
underneath the piston d'. The motion of the connecting-rods o, p, q and of the
crank-shaft m, produces a most thorough mixing up of the air and gas, contained in
the vessel n.
The compressed mixture of gas and air contained in the compressing vessel 9,
serves to feed the cylinders a, b, c. The mixture passes from space 9 to the cylinders
through the opened valve h (Fig. 1), which is opened, when the engine is started by
means of the hand-wheel ì. The mixture of gas and air passes through the
chamber and channel ¹ (Fig. 2) into the ring-shaped groove m³ (Figs. 2 and 4)
and from there through the channel n' to the delivery-valve r for the cylinder a.
The same arrangements are made for the cylinders b c. As soon as the piston i
has forced during its ascent the combustion-gases out of the cylinder a and the
piston i has commenced its down-stroke, the valve r is opened by the over-pressure in
the space 9 km n¹ and the piston i sucks up explosive mixture till the piston has
almost reached the middle position.
By this time the ignition slide-valve t on the crank-shaft m has turned so far, that
the channel (Fig. 2) is brought into connection both with the channel y of the
cylinder a and with the opening v of the lid w. The flame burning in front of the
opening ignites the explosive mixture contained in the cylinder a, and the piston i
is forced downwards. Owing to the over-pressure caused by the explosion, the
valve is shut immediately, and connection with the reservoir g is broken off thereby.
As the channels is but narrow, the connection betweens and y is interrupted as
soon as the explosion occurs. & is an opening in the side of the cylinder, which
brings the channel y in connection with the cylinder.
When the piston i has reached its lowest position, the burnt gases pass through the
channel z into the rotating slide t. From the latter they escape through the
channel a¹ a¹ (Fig. 2) and pipe c¹ into the open air. These mechanisms come into
operation in each of the three cylinders abc in succession. Figs. 6, 7, 8 and 9
illustrate the different positions of the rotating ignition slide-valve t. During the
ascent of the cylinder-pistons (for instance when piston i ascends), all the combustion-
gases are forced out of each respective cylinder.
The way in which the supply of gas is conducted to the motor and regulated and
the contrivance for facilitating the starting of the motor still remain to be described.
The combined gas- and air-valve e (Fig. 2) receives its supply of gas through the
pipe of, pipe q' and the main-gas-feed-pipe m¹. A piston-slide pl is inserted between

page_text: pipes o and q and is operated on by the spring n¹. If the pressure in 7 rises too
much owing to overfeeding on the part of the pump di, then the gas-pressure shoves
the piston-slide p¹ back. The result of this is, that the connecting-passage between
pipes of and q¹ is narrowed and but little gas can pass through pipe o into the mixing
vessel n.
The gas and air mixture in n contains therefore less explosive gas and
consequently both the power and the speed of the engine are lessened.
The pressure in the space 9 could however increase in spite of the diminished
supply of explosive gas, and in order to prevent this, a valve r is attached to the
pump-piston d¹ (Fig. 1). The valve r' is always kept shut by a spring s¹. Whenever
the pressure rises to high in the pump-chamber and in the space g, the valve r¹ opens
and allows an adequate quantity of gas to rush back into the space n.
This valve can be applied direct between the spaces g and n instead of to the pump-
piston, as Fig. 12 shows. The arrangement of the valve (Fig. 12), which is
pressed down by the spring k², offers the advantage, that the valve can be weighted
as may be desired by compressing its spring by means of the nut 1. m³, n³, o³ are
the feed-channels for this arrangement.
is
The starting contrivance for the motor consists in the water-pipe a¹ and the gas-
pipe v¹¹. The object of it, is to produce, before starting the motor, a complete
mixture of gas and air, which is ready for exploding immediately. The space g
partly filled in any desirable manner with water, and the water-cock a¹ and the gas-
cock w¹ are both turned on together. The cock w¹ is in connection with the main
gas pipe m. The water flows out through the cock r¹ and gas rushes in through the
When all the water bas run out of g, the cocks ¹ and w² are closed;
the gas, that has rushed in, mingles with the air, that was contained in g.
cock w¹.
But as the pump furnishes more compressed gas than the cylinders can use, a
compressed mixture is formed in g after the first few revolutions. This is required
for driving the motor. The first non-compressed mixture suffices to start the
engine.
If the operation just described is repeated, that is to say, if water is let occasionally
into the space g, and allowed to run off gradually though the cock x¹, the engine can
be cooled thereby, whenever necessary.
Mention must still be made of two modifications, which can be applied to the
arrangement just described. They consist in a modified ignition slide-valve and in a
modified gas distributing-slide-valve for the cylinders.
The modified ignition-slide-valve is represented in Figs. 14 to 16. In this case
the channels of the ignition slide-valve is lengthened and bent in the shape of the
letter U, for the purpose of preventing the gas-flame x from being blown out by
the over pressure of explosive gases in the cylinder. By means of this contrivance
the end of the channels first comes into connection with the channel y (Fig. 14);
in this position then is still no connection between the channels and the opening &
of the stationary lid w. A compressed mixture of gas and air passes into s s¹ and fills
this channel (see Fig. 14). y is then shut off from s s¹ (see Fig. 15). Finally the
opening pins passes by v for a moment, and the mixture contained in s s¹ explodes.
But as and the opening y are shut off again in the next moment, the exploding
flame strikes into the channel y of the cylinder and produces a safe explosion.
This
In Fig. 10 another modification is shown. It relates to the conducting of the
supply of gas to the cylinders. In this case, a rotating slide-valve f* for the gas-feed
is applied and is mounted like the ignition-slide-valve, on the crank-shaft m.
rotating ignition slide-valve is provided with the channel e (Figs. 10 and 11), and the
delivery valves r for the cylinders are rendered superfluous by it. The supply of gas
is forwarded automatically to the cylinders of the motor by the channel e in con-
nection with the channels in the lid d' (Fig. 10).

page_text: Improvements in Gas-motors.
I, JACOB FABER of Elberfeld in the Kingdom of Prussia, German Empire, engineer,
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:
These improvements relate to high speed gas motors. They consist firstly, in the
starting contrivance for the gas motors, by means of this starting contrivance the
motors can be set in motion in the simplest manner imaginable. These improvements
.consist further in the arrangement, and employment of several power-developing
"cylinders, which operate successively, and have one common rotating slide-valve,
which serves as a gas regulator, and distributer. Thirdly they consist in the use of a
mixing-space-chamber for gas and air in connection with a compressing-chamber.
The common crank-shaft for the cylinders has its bearings in the mixing-space for gas

gases. These improvements consist finally in the arrangement of a regulator-valve
which is fitted between the gas mixing-space and the compressing-space, and serves
to regulate the effect of the compressing-pump.
These improvements are represented in Figs. 1 to 19 of the accompanying
drawings.

motor provided with three cylinders. Fig. 2 likewise shows a longitudinal section on

page_text: Comment of the engine represented
which it works is as follows:
the way u
a b c are three cylinders open on the inside; their pistons i, k, I drive the common
crank-shaft m by means of the connecting-rods o p q. The crank-shaft m has its
bearings in the hollow vessel n formed by the frame of the engine. This hollow
vessel is the space for mixing the gas with atmospheric air that operates in the
cylinders. The pump-piston d' which is connected with the shaft m by means of the
rode is likewise contained in this hollow vessel and works in it.
During the down-stroke of the piston d¹, the gas which is in the pump cylinder is
compressed and forced through the channel k¹ (fig. 13) to the delivery-valve f, and
from there through the channel into the pressure-vessel g. During the down-
stroke the piston sucks up another charge of gas and air through the channel ƒ (fig. 2)
into the space n.
The gas and air are sucked up together by the lifting of the
combined valve e; the air rushes to the valve e through the pipe of, whereas the gas
streams to it through the inner pipe o*, which is in direct connection with the main-
gas pipe. When the piston rises (fig. 13), the mixture of gas and air in the space n
passes through the suction-valve g³, and the channel g' into the space underneath the
piston d¹. The motion of the connecting-rods o p q, and of the crank-shaft m,
produces a through mixing of the air and gas, contained in the vessel n.
The compressed mixture of gas and air contained in the compressing vessel g,
serves to feed the cylinders a, b, c. The mixture passes from space g to the cylinders
through the valve h (Fig. 1), which is opened, when the engine is started, by means
of the hand-wheel. The mixture of gas and air passes through the chambor k¹ and
channel (fig. 2) into the ring-shaped groove m (Figs. 2 and 4) and from there
through the channel n¹ to the delivery-valve r.
The same arrangements are made for the cylinders 6 & C. As soon as the piston i
has forced, during its ascent, the combustion-gases out of the cylinder a, and the
piston i has commenced its down-stroke, the valve r is opened by the over pressure in
the space gk l m n¹ and the piston i sucks up explosive mixture till the piston has
almost reached the middle position.
By this time the ignition-slide-valve t on the crank-shaft m has turned so far, so
that the channels (fig. 2) is brought into connection both with the channel y of the
cylinder a, and with the opening of the cover to. The flame burning in front of
the opening ignites the explosive mixture contained in the cylinder a, and the
pistoni is forced downwards. Owing to the over pressure caused by the explosion,
the valve is shut immediately, and connection with the reservoir q is cut off thereby.
As the channels is but narrow, the connection between us and y is interrupted as
soon as the explosion occurs. q³ is an opening in the side of the cylinder, which
brings the channel y in connection with the cylinder.
"'
When the piston i has reached its lowest position, the burnt gases pass through the
channel z into the rotating slide t. From the latter they escape through the
channels a¹ a¹ (fig. 2) and pipe c¹ into the open air. This arrangement comes to bear
with each of the three cylinders a b c in succession. Figs. 6, 7, 8 and 9 illustrate the
different positions of the rotating ignition-slide-valve t. During the ascent of
the cylinder-pistons (for instance when piston i ascends), all the combustion-gases are
forced out of each respective cylinder.
The way in which the supply of gas is conducted to the motor and regulated, and
the contrivance for facilitating the starting of the motor still remain to be described.
The combined gas and air valve e (fig. 2) receives its supply of gas through the
pipe o, pipe q and the main-gas-feed-pipe m¹. A piston-slide p' is inserted between
pipes o' and ', and is operated on by the spring n'. If the pressure in g rises too
much, owing to over-feeding on the part of the pump d, then the gas-pressure shoves
the piston-slide p¹ back. The result of this is, that the connecting-passage between
pipes o' and q is reduced and but little gas can pass through pipe o* into the mixing-
vessel n.
The gas and air-mixture in n contains therefore less explosive gas, and
consequently both the power and the speed of the engine are reduced.
The pressure in. the space. g could however increase in spite of the diminished
+

page_text: supply of explosive gas, and to prevent this; a valve 1 is attached to the pump
piston d¹ (fig. 1). The valve r is always kept shut by a spring s¹. Whenever the
pressure rises too high in the pump-chamber and in the space g, the valve r¹ opens
and allows an adequate quantity of gas to rush back into the space n.
This valve can be applied direct between the spaces g and n instead of to the pump
piston, as fig. 12 shows. The arrangement of the valve (fig. 12), which is pressed
down by the spring offers the advantage, that the valve can be weighted as may be
desired by compressing its spring by means of the nut l². m², n², o³ are the feed-channels
for this arrangement.
The starting contrivance for the motor consists in the water-pipe r¹ and the gas
pipe v¹.
The object of it, is to produce, before starting the motor, a complete mixture of gas
and air, which is ready for exploding immediately. The space g is partly filled in any
desirable manner with water, and the water-cock x and the gas-cock w are both
turned on together. The cock o¹ is in connection with the main-gas-pipe m². The
water flows out through the cock x¹ and gas rushes in through the cock w¹. When
all the water has run out of g, the cocks ¹ and w¹ are closed, the gas that has rushed
in mingles with the air that was in the space g.
But as the pump furnishes more compressed gas than the cylinders can use, a
compressed mixture is formed in g after the first few revolutions. This is required
for driving the motor. The first non-compressed mixture suffices to start the
engine.
If the operation just described is repeated, that is to say if water is let occasionally
into the space g and allowed to run off gradually through the cock x¹ the engine can
be cooled thereby, whenever necessary.
Mention must also be made of two modifications, which can be applied to the
arrangement just described. They consist in a modified ignition-slide-valve, and in a
modified gas-distributing-slide-valve for the gas.
The modified ignition-slide-valve is represented in Figs. 14 to 16. In this case the
channels of the ignition-slide-valve is lengthened and bent in the shape of the letter U
for the purpose of preventing the gas-flame a from being blown out by the pressure of
explosive gases in the cylinder. By means of this contrivance the end of the channel s
first comes into connection with the channel y (fig. 14); in this position there is no
connection between the channels and the opening of the stationary cover w. A
compressed mixture of gas and air enters ss' (fig. 14) and fills this channel (see fig. 14).
y is then shut off from s¹ (see fig. 15). Finally the opening pin ss' comes opposite v
for a moment, and the mixture contained in s s¹ explodes. But as v and the opening y
are shut off again in the next moment, the exploding flame strikes into the channel
of the cylinder and produces a safe explosion.

This
In Fig. 10 another modification is shown. It relates to the conducting of the
supply of gas to the cylinders. In this case, a rotating slide-valve f* for the gas-feed
is applied, and is mounted like the ignition-slide-valve on the crank-shaft m.
rotating ignition slide-valve is provided with a channel e³ (figs. 10 and 11) and the
delivery valves of the cylinders are rendered superfluous. The supply of gas is led
automatically to the cylinders of the motor by the channel e in connection with the
channels in the lid d (Fig. 10).
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1) The arrangement and use of a number of cylinders a b c working in rotation,
in combination with a common rotating crank shaft m, and ignition valve for the
purpose as described.
2) The arrangement and use of a number of cylinders a b c working in rotation on
a common crank shaft, and in combination with a common rotating gas distributing
valve.
3) The arrangement of the crank shaft of the gas motor passing gas tight through

page_text: the mixing chamber n in combination with the chamber a fed from the mixing
chamber n by means of the pump d for the purpose as described.
4) The arrangement of a regulating valve between the mixing and pressure
chambers for the purpose as described.
5) The arrangement of a regulating valve in the piston of the pump d¹ opening in
the direction of the mixing chamber for the purpose as described.
6) The arrangement of a gas pressure chamber g in combination with a gas pipe
and a water pipe, both being provided with a valve for the purpose as described.
7) The arrangement of a gas pressure chamber g in combination with a gas dis-
tributing valve for the purpose as described.
