page_text: I, GEORGES ALFRED FLEURY, of 76, Rue-Chardon Lagache, Paris, France,
Mechanician; do hereby declare the nature of this invention to be as follows:-
My invention relates to an explosion engine chiefly charcterized by the
employment of a movable cylinder enabling the volume of the explosive mixture
in the explosion chamber to lie increased, the complete discharge of the burnt
gases to be effected, and increased power to be obtained.
Reference is to be had to the accompanying drawings forming part of this
specification wherein Figure 1 is an elevation and Figure 2 a plan of the im-
proved engine, Figure 3 is a vertical section on line 1-2 Figure 2, Figure 4 is

the gases, and the suction pipe x connected to the carburetter by any suitable
flexible pipe. The ignition cam y is keyed on the spindle of wheel j.
The action is as follows:-At the commencement of the first phase the moving
cylinder 6 is at the lower end of its stroke and touches piston a so that neither
air nor gas is contained in cylinder b. During this first phase, denoted by the
semi-revolution 1 (Figure 5), the piston a descends and cylinder 6 is raised by
the cam h actuated by wheel j, by this movement the inhalation of the gases
supplied through pipe a from the carburetter is effected, the automatic suction
valve s opening to give passage to said gases which correspond in volume to the
stroke of the piston, plus that of the moving cylinder. During the second
phase 2 (Figure 7) the piston a is raised by connecting rod c and the moving
cylinder 6 remains stationary; the cylinder cannot descend by its own weight
since it is maintained by the cam and by the friction of the piston moving in
the same direction, thus lessening the force expended in raising the moving
cylinder by means of cam which is partly of semi-cylindrical contour thus per-
mitting any required lead of the ignition. During the third phase 3 (Figure 7)
expansion and explosion, when the electric spark ignites the explosive mixture,
the piston a descends under the downward pressure of the explosion of the gas
inhaled in volume equal to the stroke of the piston and the inhaling stroke of the
moving cylinder. The volume of gas being so much greater in this engine, the
motive power developed will thus be correspondingly increased. During the
fourth phase 4 (Figure 8), the piston a returns to its initial position and the
moving cylinder 6 descends under the action of cam i. During this movement
the exhaust valve is opened by cam 1 (Figure 9) acting through rod m and
lever o and the burnt gases are discharged through the telescopic pipe u into the
usual exhaust chamber situated at any suitable point.
This system of engine may comprise several moving cylinders and it is to be
understood that the form, dimensions, details of construction, of the engine
having one or several moving cylinders, may be varied without departing. from
the principle of the invention.

An Improved Explosion Engine.
I, GEORGES, ALFRED FLEURY, of 76, Rue Chardon-Lagache, Paris, France,
Mechanician, 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:-
My invention relates to an explosion engine chiefly characterized by the em-
ployment of a movable cylinder whereby to enable the volume of the explosive
mixture in the explosion chamber to be increased, the complete discharge of
the burnt gases to be effected, and increased power to. be obtained.
Reference is to be had to the drawings accompanying my Provisional Specifi-
cation wherein Figure 1 is an elevation and Figure 2 a plan of the improved en-
gine. Figure 3 is a vertical section on line 1-2, Figure 2, Figure 4 is a vertical
section on line 34Figure 2, Figure 5 is a vertical section on line 5-6 Figure 4,

first or
inhaling phase, Figure 6 is a vertical section on line 7-8 Figure 5.
Figure 7 shews the position of the cams during the second or." compression
phase and also during the third or "explosion" phase, Figure 8 shews the position
of the same cams during the fourth phase at which the burnt gases are ex-
hausted," Figure 9 shews separately details of the cam which operates the exhaust
valve through a rod and lever. Figure 10 is a detail of the cam which produces
the ignition contact. The same letters of reference denote like parts in all the
Figures.
As shown in Figures 3 and 4 the piston a works in a moving cylinder b and
is connected by rod c with the crank pin of the fly wheels d keyed on the driving.
shaft. Upon this shaft is a pinion (Figure 4) which gears with a speed re-
ducing wheel whose axis carries a cam 7 which operates the exhaust valve q
through the medium of a lever o pivoted at p and rod m moving in a guide vand
pressed towards the cam by a spring n. hand are cams operated by wheel j
and working within a frame attached to a rod g fixed to the moving cylinder b.
This moving cylinder 6 is fitted to work within a stationary cylinder e and is
suitably guided by means of rods f terminated by stop-nuts, and upon its upper
end are the compression cock the automatic inhaling valve s, the ignition
device t, the telescopic exhaust pipe u for the gases, and the suction pipe a
(Figures 1 and 2) connected to the carburetter by a suitable flexible pipe. The
ignition camy (Figure 10) is keyed on the spindle of wheel j.
The action is as follows:-When the engine is at the commencement of the
first phase the moving cylinder is at the lower end of its stroke and touches
piston a so that neither air nor gas is contained in cylinder b. During this first
phase (denoted by the semi-revolution 1 (Figure 5) the piston à descends and
cylinder is raised by the cam 4 actuated by wheel j; by this movement the
inhalation of the gases supplied through pipe a from the carburetter is effected,
the automatic inhaling valve s opening to give passage to said gases which corre-
spond in volume to the stroke of the piston, plus that of the moving cylinder.
During the second phase (2 Figure 7) the piston a is raised with the aid of.
the connecting rod c and the moving cylinder & remains stationary. The latter
cylinder cannot descend by its own weight since it is maintained by the cam and
by the friction of the piston moving in the same direction, thus lessening the
force expended in raising the moving cylinder by means of cam h which being
partly of semi-cylindrical contour permits of any required lead of the ignition
being obtained.
During the third phase (3 Figure 7-"expansion and explosion") when the
electric spark ignites the explosive mixture, the piston a descends under the
downward pressure of the explosion of the gas inhaled in volume equal to the
stroke of the piston and the inhaling stroke of the moving cylinder. The volume
of gas being greater in this engine than usual, the motive power developed will
be correspondingly increased.
During the fourth phase (4 Figure 8) the piston a returns to its initial position
and the moving cylinder descends under the action of cam i. During this
movement the exhaust valve is opened by cam 7 (Figure 9) acting through
rod m and lever and the burnt gases are discharged through the telescopic
pipe into the usual exhaust chamber situated at any suitable point.
This system of engine may comprise several moving cylinders and it is to be
understood that the form, dimensions and details of construction of the engine
having one or several moving cylinders,, may be varied without departing from
the principle of the invention.
Having now particularly described and ascertained the nature of the said in-
vention and in what manner the same is to be performed, I declare that what
I claim is:-
An explosion engine having one or more movable cylinders whereby to permit
of augmenting the volume of the explosive mixture in the explosion chamber

page_text: and of effecting the complete expulsion of the burnt gases, the engine being con-
structed and arranged to operate substantially as hereinbefore described and
illustrated in the drawings and for the purpose specified.
