Fig. 6. is a view of the boss & wheel box.
Fig. 8 is a view of the mixing cylinder with lighting tube entering from below.
Fig. 7. is a section of the gas apparatus with the regulating mechanism.
The construction of the pump itself is not described as it does not form part of
my invention.
The engine rests on frame a fixed on the top of reservoir A which when filled
with water serves as foundation for the engine when at work, while when the engine
is to be moved the water may be let off by outlet a' and the machine may be tilted
in the direction of the arrow (Fig. 1) so as to rest on the fly wheels B the beam y'
thus coming into an horizontal position.
The axle 6 is of conical shape. When the wheels are to serve as fly-wheels (the
machine being at work) they are fastened to the axle by being shifted by means
of wedge c against the shoulder of the axle, and the wedge c which is held in
position by peg c 1 enters with its nose into a slot in the wheelbox and boss and.
thus joins the wheel tight to the axle (Fig. 4.). When the wheels are to serve as
driving wheels wedge e is fixed in the position indicated by Fig. 5. the nose of the
wedge not entering into the slot and allowing the wheels to turn independently of
the axle.
In order to save the mechanisms from receiving shocks when driving the frame
is connected with spring F which rests on rods ff resting on axle b (see Fig. 3).
The driving gear of the engine may be seen in Figs. 1. & 2.; it is placed by
the side of the working cylinder and consists of two discs E & E¹ of which the
smaller E on crank axle b makes two revolutions to one of E. E' is attached
movable to the side of the working cylinder and is propelled by E by means of
chain E.
On the side next to the cylinder E¹ is provided with a peg e' which after one
revolution strikes against lever arm h of lever H, thus causing the other arm h¹ of
lever H to press on valve M whereby lighting tube m is opened (Fig. 7) allowing
the exploding mixture to enter the tube and produce the explosion.
On the other side of disc E¹ is a thumb piece e which when striking against
lever N causes outlet valve O to open and on the returning movement of the piston

page_text: of the working cylinder the waste gas mixture is allowed to escape by outlet o
(Fig. 1). Spring o' prevents the opening of valve O with the upward stroke of
the piston.
The mixing & gasifying apparatus peculiar to this engine consists of two (or
more) concentric cylinders the innermost being heated by flame P! (see Fig. 7).
The space between the cylinders C and C' is filled with turnings.
C
Cylinder C is provided with a number of small holes c c by which it is connected
on one side with the air tube L and on the other side with the suction tube G of
the gas engine.
C
The air entering through holes c which is already warm is still more heated in C,
there mixed with the gas produced by the gasification of the oil, benzine or petro-
leum on the well heated cylinder C' and absorbed into the working cylinder through
holes c and gas tube G.
The oil to be gasified comes from reservoir R through tube i into cylinder I
with partition in which is fixed a spindle movable vertically; on this spindle
are fixed two discs for shutting off the oil supply.
In partition there is another opening which may be increased or diminished in
size by screw Jaccording to whether more or less petroleum is to be gasified.
During the sucking action of the working cylinder and while disc E makes half
a revolution and E' makes revolution valve K (Fig. 7) & thus spindle * are
lifted, admitting a small quantity of oil which flows through the opening in the
partition into tube Q past valve and through tube into the gasifying apparatus
running down on the walls of cylinder C¹. At the moment the working cylinder
ceases sucking valve K is closed and spring & pulls spindle down thus stopping
any further supply of petroleum.
While the described process takes place and during the suction of the piston
the working cylinder absorbs from the gasifying space the gas mixed with air
through valve F and opening D (Figs. 1 & 7) stopping the supply at the same
moment when the suction ceases and valve K is shut. While the gas is now
being compressed by the down stroke of the piston disc E completes its second
and disc Ei its first revolution repeating the same process as before described by
means of pege and lever H and explosion of the compressed gas mixture. The
air being obliged to pass through the air conducting tube L which is also heated
by the Hame is warmed before entering the mixing apparatus and thus causes the
gas mixture to explode more easily.
The cock on tube L serves for introducing combustible gas or coal gas if
desired into the motor. The lighting apparatus (Fig. 7) consists of the round
burner P the flame P' of which heats the lighting tube m to red heat.
If the gas engine is to serve for other purposes, when the arrangement of the
lighting tube may be made from the bottom (see Fig. 8) m is provided with a
smaller tube m¹ with small cock m' on its lower extremity.
When the motor is started this cock must be open for the purpose of expelling
the air from the lighting tube. When the engine is at work this cock is closed.
With this arrangement-the rest of the mechanism remaining as described-
the explosion valve M is actuated by a lever which at the proper moment opens
valve M and admits the exploding mixture into lighting tube m.
The lighting
tube m leads in this case from the side into the round burner to the flame.
The pump is an ordinary suction and force pump the piston of which is
connected with crank T of crank axle b to which is also attached the piston U of
the working cylinder of the gas engine.
When the motor is to serve as a pump a regulating mechanism is fixed on the
mixing apparatus. This regulating mechanism consists of cylinder (Fig. 7) &
piston which under an ordinary pressure is pressed down by levers & spring t.
But when the pressure increases in air vessel V (see Fig. 1) which is in connection
with cylinder by means of tube piston r lifts levers and thus also valve q
(Fig. 7) the cone shutting off partly the tube q' and diminishing the oil supply.
Thus less gas is produced and the motion of the motor is retarded.

page_text: For the sake of simplicity and solidity the cover of the cylinder with valve-box
& outlet & arrangement for fixing beam is cast in one piece.
In order to start the motor a ratchet wheel W with pawl w is fixed to the axle
(see Fig. 4) which is moved by a crank. After the first explosion the axle b
turns independently of the crank and the latter may be allowed to revolve with
it or may be removed.
Having now particularly described and ascertained the nature of my said inven-
tion and the manner in which the same is to be performed I declare that what
I claim is:
1. A portable petroleum gas engine with a reservoir filled with water &
serving as foundation while the engine is at work in combination with fly
wheels arranged in such a manner that after emptying the said reservoir the
whole engine may be tilted said fly wheels serving as driving wheels after having
been disengaged from the axle substantially as described and shewn in the
drawing.
2. In such engines the reversing mechanism consisting of discs E and E¹ chain E*,
lever H, valve M, lever N & valve O substantially in the manner as and for
the purpose described and shewn in the drawings.
3. In such engines the mixing and gasifying apparatus consisting essentially
of two or more concentric cylinders charged with turnings and having access
on one side through openings c to air tube L and on the other side with gas
tube G, the innermost cylinder being heated by a flame in combination with
reservoir R cylinder I valve K and valves F & M substantially in the manner
as and for the purpose described and shewn in the drawings.
4. In such engines the regulating mechanism consisting of cylinder piston 1
levers & spring t substantially in the manner as and for the purpose described
and shewn in the drawings.
