I, LOUIS ZACHARIE STANISLAS COLOMBIER, of 25, Rue Eugène Suë, Paris, France,
Mechanician, do hereby declare the nature of this invention to be as follows:-
-
This invention relates to improvements in internal combustion engines for
auto-motor road vehicles. In this improved engine the explosion of the gaseous
mixture is effected at the end of each stroke of the piston, that is to say twice
for every revolution of the driving shaft and at about 30° from the dead point,
without compression of the gaseous mixture by the piston.
The invention is illustrated by way of example in the accompanying drawings
wherein Figure 1 represents a side elevation and Figure 2 a front
elevation of the general arrangement of the engine as applied to an
auto-motor vehicle. Figure 3 is a longitudinal vertical section and Figure 4 a
plan partly in horizontal section, of the engine separately. Figure 5 is a trans-
verse vertical section on line 1, 2 Figure 3. Figure 6 shews separately in vertical
section, the details of the vapourizer and the compression cylinder for the gaseous
mixture. Figure 7 is a vertical section on line 3. 4 Figure 6. Figure 8 is a
horizontal section on line 5, 6 Figure 6. Figure 9 is an elevation of the
reversing and variable speed mechanism. Figure 10 shews separately in vertical
section, details of the throttle valve for regulating the distribution of the gaseous
mixture in the cylinder. The same letters of reference denote like parts in all
the figures.
is a horizontal cylinder opening at each end into a vertical cylinder beach
containing a distributing valve chamber c opening into an explosion chamber e
at the end of the horizontal cylinder, the explosive mixture thus passing alter-
nately to the back and front of piston d. The ignition of the explosive mixture
is produced by the platinum; wires f which are rendered incandescent in any
suitable manner. The distributing chambers which are provided with valves g,
the functions of which will be hereinafter described, are united by a pipe h
provided with a regulating valve i for the admission of the gaseous mixture into
the chambers c. The mixture of petroleum and air is obtained by a vapourizer k
consisting of a cylindrical container divided into two compartments by a par-
tition keyed on a longitudinal shaft 12 carrying rotating blades for producing
an intimate mixture of the air and petroleum which are separately introduced
into the first compartment where they are mixed by the blades , the mixture being
then inhaled by a piston m by which it is compressed in a cylinder n to a

page_text: pressure of about one-and-a-half atmospheres and then expelled into an inter-
mediate chamber provided with à valve o and pressure gauge. The
second compartment of the vapourizer is intended to feed with petroleum, without
any admixture of air, the lamps which serve to heat the coil and the platinum
wires for igniting the mixture in the explosion chambers. Upon chamber is
branched a coil for conducting the gaseous mixture to the distributing cham-
bers the coil being heated in order that the mixture shall be supplied to the
distribution chambers at the proper temperature. After each explosion the pro-
ducts of combustion pass out through the exhaust chambers provided with
valves and through the common exhaust pipe s. The admission and exhaust
valves and are alternately actuated through levers t provided with friction
rollers by cams keyed on shaft driven from the main shaft by gear y.
The shaft also drives the shaft 12 of vapourizer and imparts reciprocating
motion to the compressing piston m by means of the crank shaft 1 whose crank
works in a slotted crosshead of piston m. Upon the main shaft 2 is keyed a fly
wheel 3 which drives the front wheels 4 of the vehicle through the medium of a
friction drum 5 keyed on a shaft 6. This shaft 6 is mounted in a pillar block 7
fitted to slide in a guide 71 (Figure 9) and opened by an eccentric 8
mounted on the spindle of the handing lever 9 in order to bring drum 5 into
frictional contact with the fly wheel 3. The change of speed and of direction
are effected by bringing the friction drum 5 nearer to, or further from, the centre
of the fly wheel by sliding the drum along the shaft 6 by means of the forked
lever 10 the direction of motion being reversed when the drum passes the centre.
The vehicle is steered by the hand lever 11 whose spindle is connected to a
rod 12 mounted on the axle 13.
The operation is as follows:-The petroleum is supplied to one of the chambers
of the vapourizer k where it is mixed with air, the mixture being then inhaled
The mixture is
by the piston m into the cylinder n provided with a valve n¹.
then compressed by the piston m to about one-and-a-half atmospheres and forced
through valve o' into chamber and thence through the coil p into the distri-
bution chambers c.
The gaseous mixture stored in the chambers c is admitted by the action of the
valves alternately to the explosion chambers e where it is ignited by the
platinum wire igniters f, the opening and closing of the admission valves and
exhaust valves r being effected alternately in proper order by the levers t and
cams driven by the main shaft.

To start the vehicle the handle 9 is moved so as to cause the eccentric 8 con-
nected therewith to move the friction drum 5 on shaft 6 into frictional contact
with fly wheel 3 which rotates through shaft 6, bevel gears 14, shaft 15, and
spur wheel 16 the front wheels of the vehicle. The change of speed is effected
by varying the radial distance of drum 5 from the centre of the fly wheel by
means of lever 10 and the reversing by causing drum 5 to pass the centre of
the fly wheel.
The vehicle may be stopped either by moving drum 5 out of contact with the
fly wheel the engine continuing to run without doing any work, or by closing
the valve i so as to shut off the supply of gaseous mixture from the engine.

page_text: the same is to be performed to be particularly described and ascertained in and
by the following statement:-
This invention relates to improvements in internal combustion engines for
auto-motor road vehicles. In this improved engine the explosion of the gaseous
mixture is effected at the end of each stroke of the piston, that is to say twice
for every revolution of the driving shaft and at about 30° from the dead point,
without compression of the gaseous mixture by the piston.
The invention is illustrated by way of example in the drawings accompanying
my Provisional Specification wherein Figure I represents a side elevation and
Figure 2 a front elevation of the general arrangement of the engine as applied to an
auto-motor vehicle. Figure 3 is a longitudinal vertical section and Figure 4 a
plan partly in horizontal section, of the engine separately. Figure 5 is a trans-
verse vertical section on line 1, 2 Figure 3. Figure 6 shews separately in vertical
section the details of the vapourizer and the compression cylinder for the gaseous
mixture. Figure 7 is a vertical section on line 3, 4 Figure 6. Figure 8 is a

the figures.
a is a horizontal cylinder opening at each end into a vertical cylinder beach
containing a distributing valve chamber c opening into an explosion chamber e
at the end of the horizontal cylinder, the explosive mixture thus passing alter-
nately to the back and front of piston d. The ignition of the explosive mixture
is produced by the platinum wires or rods f (Figure 4) which are rendered incan-
descent in any suitable manner. The distributing chambers which are provided
with valves g the functions of which will be hereinafter described, are united by
a pipe provided with a regulating valve (Figure 10) for the admission of the
gaseous mixture into the chambers c.
The mixture of petroleum and air is obtained by a vapourizer k (Figure 6)
consisting of a cylindrical container divided into two compartments by a par-
tition keyed on a longitudinal shaft / carrying rotating blades 7 for producing
an intimate mixture of the air and petroleum which are separately introduced
into the first compartment where they are mixed by the blades, the mixture being
then inhaled by a piston m (Figure 7) by which it is compressed in a cylinder n
to a pressure of about one-and-a-half atmospheres and then expelled into an inter-
mediate chamber o (Figure 6) provided with a valve and pressure gauge. The
second compartment of the vapourizer is intended to feed with petroleum, without
any admixture of air, the lamps which serve to heat the coil and the platinum
wires for igniting the mixture in the explosion chambers. Upon chamber o is
branched a coil p for conducting the gaseous mixture to the distributing cham-
bers c, the coil being heated in order that the mixture shall be supplied to the
distribution chambers at the proper temperature. After each explosion the pro-
ducts of combustion pass out through the exhaust chambers provided with
valves and through the common exhaust pipe s. The admission and exhaust
valves 9 and are alternately actuated through levers provided with friction
rollers u (Figure 5) by cams keyed on shaft driven from the main
shaft by bevel gear y..
The shaft also drives the shaft 2 of vapourizer k and imparts reciprocating
motion to the compressing piston m by means of the crank shaft 1 whose crank
works in a slotted crosshead of piston m. Upon the main shaft 2 is keyed a fly
wheel 3 which drives the front wheels 4 of the vehicle through the medium of a
friction drum 5 keyed on a shaft 6. This shaft 6 is mounted in a pillar block 7
fitted to slide in a guide 71 (Figure 9) and operated by a cam S (Figure 4)
mounted on the spindle of the handing lever 9 in order to bring drum 5 into
frictional contact with the fly wheel 3.
The change of speed and of direction are effected by bringing the friction

page_text: drum 5 nearer to, or further from, the centre of the fly wheel by sliding the drum
along the shaft 6 by means of the forked lever 10, the direction of motion being
reversed when the drum passes the centre.
The vehicle is steered by the hand lever 11 whose spindle is connected to a
rod 12 mounted on the axle 13.
The operation is as follows:-The petroleum is supplied to one of the chambers
of the vapourizer k where it is mixed with air, the mixture being then inhaled
by the piston m into the cylinder n provided with a valve n¹. The mixture is
then compressed by the piston m to about one-and-a-half atmospheres and forced
through valve o' into chamber and thence through the coil p into the distri-
bution chambers c.
and
The gaseous mixture stored in the chambers c is admitted by the action of the
valves alternately to the explosion chambers e where it is ignited by the
platinum wire igniters f, the opening and closing of the admission valves
exhaust valves r being effected alternately in proper order by the levers
cams driven by the main shaft.
and
To start the vehicle the handle 9 is moved so as to cause the cam 8 con-
nected therewith to move the friction drum 5 on shaft 6 into frictional contact
with fly wheel 3 which rotates through shaft 6, bevel gears 14, shaft 15, and
spur wheel 16, the front wheels of the vehicle. The change of speed is effected
by varying the radial distance of drum 5 from the centre of the fly wheel by
means of lever 10 and the reversing by causing drum 5 to pass the centre of
the fly wheel.
The vehicle may be stopped either by moving drum out of contact with the
fly wheel, the engine continuing to run without doing any work, or by closing
the valve i so as to shut off the supply of gaseous mixture from the engine.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. The herein described gas engine for auto-motor vehicles wherein the dis-
tribution of the gaseous mixture to the ends of the working cylinder is effected
without compression by the piston by the combination with the admission valves y
and the exhaust valves r, of levers t and cams for producing the alternate
opening and closing of the admission valves and of the exhaust valves sub-
stantially as specified.
2. In the herein described gas engine wherein the gascous mixture is distri-
buted to the two ends of the working cylinder without compression by the piston,
the vapourizer having two compartments containing rotating vanes in
combination with a compression cylinder n having a piston m whereby the mixture
is forced through a chamber o and coil p to the distribution chamber e sub-
stantially as specified.
3. In the herein described gas engine wherein the gaseous mixture is distri-
buted to the two ends of the working cylinder without compression by the
piston, the change speed and starting gear consisting of a friction drum 5 placed
in contact with a fly wheel 3 by the movement of a sliding bearing 7 by means
of a cam 8 substantially as specified.
