Improvements in Petroleum Motors and the like.
I, FERDINAND PAUL GAUTIER of 21 Boulevard Poissonniere Paris, in the
Republic of France, Engineer, do hereby declare the nature of this invention to
be as follows:-
This invention relates to petroleum and similar motors.
The motor forming the subject of the present invention comprises four cylinders
mounted upon a base of appropriate shape and enclosing two crank shafts con-
nected by means of pinions in such a manner that oue only is utilized as the
motor shaft, and a shaft over which a sleeve with cams is slid which is connected
by a lever or in any other manner to the sleeve of the governor appertaining to
the shaft serving as the motor shaft.
Each cylinder encloses a piston the connecting rod of which is connected to
a crank shaft and is surmounted by an explosion chamber having at the side
two valves acting from below upwards under the influence of a suitable spring
and serving, one for the admission of the gas arriving through the inlet pipe and
the other for the discharge of the burnt gases which flow through the discharge
pipe.
The pistons on one side are coupled to one shaft; and the pistons on the other
side are coupled to the other shaft and the cranks of these two shafts are
arranged at an angle of 180 degrees.
The admission valves for the discharge are arranged in one and the same box
on which the discharge pipes are arranged, the said box is separated into two
by a horizontal diaphragm, serving as a seat for the valves, and by vertical
partition walls which isolate the two cylinders and the different valves. The
same is the case with the valves on the other side, which are arranged in one
and the same box for the use of the cylinders on that side.
Each explosion chamber has a platinum tube for the ignition of the admitted
gas and these tubes are raised to red heat by the aid of a small Aelopile lamp
or by a lamp of any other suitable kind.
Each admission valve is rigid with a rod suitably guided and the extremity
of which rests upon a lever oscillating upon a suitably supported axis and bearing,
at its opposite extremity upon a cam appertaining to the aforesaid sleeve con-
nected to the governor, as has been above stated. The same is the case with
the rods of the discharge or exhaust valves which rest upon levers, bearing upon
cams. It should be observed however that the cams of the discharge or exhaust
valves are larger than those of the admission valves, so that, when under the
influence of the governor, the cam sleeve is being displaced, the exhaust valves
remain always in communication with their respective cams, whereas the admission
valves are prevented from being acted upon by their cams. It should also be
observed that the cam sleeve is constantly driven toward the governor by means
of a spring.
The motor pistons move in pairs, the gas and the air which feed one pair
arrive at the inside of the compartment provided between the two explosion
chambers of this pair and pass into the cylinders each time when the admission
valves are lifted under the action of the corresponding cams of the cam sleeve.
When the speed increases, the sleeve becomes longitudinally displaced and its
cams for actuating the admission remain no longer in communication with the

page_text: levers of the admission valves. These valves, in this case remain closed and the
gas no longer enters the explosion chambers, whilst, as has been stated herein-
before, the exhaust valves continue their action.
The holes provided above the valves and blocked by stoppers serve to facilitate
the operations of dismounting and cleaning the valves.
The junction or connection between the two crank shafts has the advantage
of presenting a perfect equilibrium in the movement of the pistons and of the
said shafts.
The governor is keyed upon the shaft; the same transmits its movement to
the cam sleeve by the aid of a small lever engaging at one extremity with the
slide of the governor and at the other with that of the sleeve. The shaft of
this sleeve carries a tooth wheel driven by another fixed to the governor and
being of about half the diameter of the former.
In conclusion it must be understood, that I do not limit myself to the forms
and dimensions of each of the constituent parts of my motor device and the sail
motor may be constructed of any size, and may be used for any suitable purpose
and need have only ene single pair of motor pistons, if found preferable.

1, FERDINAND PAUL GAUTIER, of 21 Boulevard Poissonniere, Paris, in the
Republic of France, 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 :-
This invention relates to petroleum and similar motors.
The motor which forms the object of this invention is represented in the
accompanying drawings, in which
Figure 1 is a vertical section of the whole motor in question.
Figure 2 is an horizontal section on the line 1, 2, 3, 4 of Figure 1.
Figure 3 is a section of the valve box on the line 5-6 of Figure 1; and
Figure 4 is a section through the governor on the line 7-8 of Figure 1.
The improved motor comprises four cylinders A A1 A2 A3 mounted upon a
base B of appropriate shapes and enclosing two crank shafts C and C' connected
by means of pinions D and D' in such a manner that one only is utilized as the
motor shaft, and a shaft E over which a sleeve F with cams is slid which is
connected by a lever or in any other manner to the sleeve of the governor G
appertaining to the shaft C serving as the motor shaft.
Each cylinder encloses a piston a the connecting rod 6 of which is connected to
a crank shaft Cor Cand is surmounted by an explosion chamber c having at the
side two valves d and e acting from below upwards inder the influence of a suitable
spring and serving, one for the admission of the gas arriving through the inlet
pipe and the other for the discharge of the burnt gases which flow through the
discharge pipe g.
The pistons u on one side are coupled to the shaft C; and the pistons on the
other side are coupled to the other shaft Can the cranks of these two shafts are
arranged at an angle of 180 degrees.
The admission valves d and the valves e for the discharge are arranged in one
and the same box H on which the inlet and discharge pipes fand g, are arranged,
the said box is separated into two by a horizontal diaphragm, serving as a seat for

page_text: the valves, and by vertical partition walls which isolate the two cylinders and the
different valves, as indicated in Figure 3. The same is the case with the valves
on the other side, which are arranged in one and the same box H for the use of
the cylinders A' and A*.
Each explosion chamber has a platinum tube h for the ignition of the admitted
gas and these tubes are raised to red heat by the aid of a small Aelopile lamp or
by a lamp of any other suitable kind.
The admissin valves are rigid with rods suitably guided and the
extremities of which rest upon levers jjj oscillating upon a suitably supported
axis and bearing, at their opposite extremities upon cams kkk appertaining to
the aforesaid sleeve F connected to the governor, as above stated. The same is
the case with the rods 1, 1, 1, 13, of the discharge or exhaust valves which rest
upon levers m m³, m², m³ bearing upon cams n, n', n², n³. It should be observed
however that the cams of the discharge or exhaust valves are larger than those of
the admission valves, so that, when under the influence of the governor, the cam
sleeve is being displaced, the exhaust valves remain always in communication with
their respective cams, whereas the admission valves are prevented from being
acted upon by their cams. It should also be observed that the cam sleeve is
constantly driven toward the governor by means of a spring.
The motor pistons move in pairs, the gas and the air which feed one pair arrive
at the inside of the compartment provided between the two explosion chambers of
this pair and pass into the cylinders each time when the admission valves are lifted
under the action of the corresponding cams of the cam sleeve.
When the speed
increases, the sleeve becomes longitudinally displaced and its rams for actuating
the admission remain no longer in communication with the levers of the admission
valves. These valves, in this case remain closed and the gas no longer enters the
explosion chambers, whilst, as has hereinbefore been stated, the exhaust valves
continue their action.
The holes provided above the valves and blocked by stoppers o, o', 02,
08, 0
..... serve to facilitate the operations of dismounting and cleaning the
valves.
The junction or connection between the two crank shafts CC has the advantage
of presenting a perfect equilibrium in the movement of the pistons and of the said
shafts.
The governor is keyed upon the shaft C; the same transmits its movement to
the cam sleeve by the aid of a small lever p engaging at one extremity with the
slide of the governor and at the other with that of the sleeve. The shaft of this
sleeve carries a tooth wheel g driven by another q fixed to the governor and being
of about half the diameter of the former.
In conclusion it must be understood, that I do not limit myself to the forms and
dimensions of each of the constituent parts of my motor device and the said motor
may be constructed of any size, and may be used for any suitable purpose and need
have only one single pair of motor pistons, if found preferable.
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:-
The improved petroleum motor as a whole and in its constituent parts,
substantially as herein before described with reference to the accompanying
specimen drawing.
