This invention is divided into three parts: of these the first relates to making the
explosive mixture; the second to the exploding of the same; the third to the motor
in which the gas is exploded.
The mode of forming the explosive mixture consists in spraying out the liquid
hydrocarbon into a current of air by bending back the hairs of a brush saturated
with it and suddenly releasing them. This can be done by using a revolving brush
or an endless band of brushes running on pulleys dipping partially into the liquid
hydrocarbon and exposed to a current of air in the upper portion of their travel
where they come against projecting ribs which bend the bristles of the brush as
Prine 1031

page_text: they pass beneath them, and suddenly release them as they pass forward beyond
the said ribs
The explosion instead of being worked by extraneous battery or Ruhmkorff coil,
is brought about by a spark formed by an electro-magnetic appliance on the motor
itself;
this can be on the continuous rotation principle or by magnetic inductors
re-acting electrically by producing one or many sparks under a periodic mechanical
impulsion. The plan preferably followed by Mr. Marcus is as follows: Two
segments of an iron ring or cylinder, form the poles of a powerful magnetic
reservoir formed of a ring of an indefinite number of magnet bars arranged like
the bars of a lantern with spaces between, and an iron base plate to which they
are screwed. A square plate of any non-magnetizable material covers and protects
the annular face of the apparatus. The bars radiate from the two poles outward
touching same. Inside of these poles revolving on a central axis is a core formed
of a bar with broad T ends; round this bar is a coil of covered wire well insulated
with one end connected with the metallic body of the apparatus and the other to
an insulated ring or collar on the revolving axis; two plates, one on each side
almost touching the annular poles aforesaid, electrically join the broad heads of the
core and the axis-The wire is connected to the collar aforesaid by a spring and
projecting iron pin, but is isolated from the square cover by an isolating socket.
The axis has a variable motion given it by means of a pin on a wheel revolving
eccentrically to the axis of the electric-apparatus catching in a lever keyed on said
axis. This wheel is geared to run synchronously with the motor by means of a
belt with nobs or bars at invervals fitting into depressions or grooves in the two
wheels. The other end of the magnetic axis carries a scroll cam, a large part of
which is circular, which actuates a bell-crank lever governed by a spring or weight,
which lever suddenly breaks the contact of two wires in the motor cylinder at
stated intervals and so causes the spark
The motor can be of various forms, vertical, horizontal, or inclined; it differs
from others in that if compressed air be used the same piston cylinder compresses
the air and receives the force of the explosion, the explosion taking place on one
side of the cylinder, the compression on the other. The compressed air goes to a
gasometer or holder and from thence partly to the vapourizer and partly direct to
the cylinder.
The waste gases escape through another port into the air. The main shaft
worked by connecting rods and crank from the crosshead carries the pulleys which
work the magneto-electric machine and vapourizer also the fly wheel excentrics for
working the valves regulating the admission and exhaust. A water jacket is
placed round the cylinder to keep it cool.
Where compression is not required the cylinder can be open, in which case an
oscillating piston rod and bellcrank lever, and connecting rod and crank can work
the main shaft placed near the explosion end of the cylinder.
This makes a very
compact form of machine-cams or eccentrics on this shaft working the valves.
The valves and mechanism in each case are so arranged as to supply the right
quantities and compression at the right moment and to make the break of contact
and consequent spark just at the moment when, the current changing, the
largest amount of electricity is obtainable and to time this event the moment the
piston fairly begins its return stroke.

This invention relates to certain improvements in the construction of gas engines
and it has for its object First, to so construct the piston cylinder of the engine as
to adapt it for use as an air compressing pump. Secondly, to provide means
whereby the liquid employed to produce the explosive gas is thoroughly atomised,
or vaporized and which means are of simple construction and operation and
whereby highly volatile and explosive liquids may be employed and the air
compressor dispensed with. Third, to provide a means for automatically igniting
and exploding the explosive gas by an electric spark produced from a current
generated by a magneto electric generator thereby dispensing with the usual
batteries and which is effective in a dry as well as a damp atmosphere and entirely
independent of all slide valve mechanism. Fourth, to effect the ignition and
explosion of the gas within the exploding chamber of the cylinder by an electric
spark produced by the current generated by the magneto-electric apparatus thereby
dispensing with the auxiliary flame or the Puhmkorff apparatus for producing the
spark itself and avoiding all danger of premature explosion, or fire. Fifth, to
simplify the construction of the entire engine and to so connect the various parts
by simple mechanical appliances as to produce an automatic timed and regular
co-operation of said parts so that but little care and attendance will be necessary
and but little power required when compared with other engines of this class, and
Last, to adapt the engine to be worked in any position and used either as a
stationary or locomotive engine its weight being comparatively small and the
engine taking up but a limited space is in fact adapted for general use. The
invention consists,
Firstly, in the method of vaporizing or atomizing the liquid from which the
explosive gases are produced by the admixture with such atomized liquid of a
certain volume of atmospheric air.
Secondly, in the means employed for carrying out the above method.
Thirdly, in the combination with the engine of a magneto-electric generator
for generating the necessary electricity from which a spark is produced to
ignite and explode the explosive gases and in the means employed for effecting
the same.
Fourthly, in the construction and arrangement of the operating mechanism of
the engine all as hereinafter described and as shown in the accompanying drawings
in which Fig. 1, a side elevation partly in section and
Fig. 2, is a front elevation
Fig. 3, a plan view of a gas-engine with a vertical piston cylinder constructed
according to my invention,

cylinder and
Fig. 5, is an end elevation

page_text: · Fig. 6. is a detail view of the mechanism that operates the admission and
exhaust valves
Figs. 7 & 8 show respectively a longitudinal and a transverse section of the
improved atomizer, and
!.
Figs. 9 & 10 are like views of a modification in the construction of the same,
Figs, 11, 12, & 13 show in elevation, in vertical longitudinal section and by an
end view, a magneto-electric generator and
Fig. 14 shows its application to the engine for igniting and exploding the gases.
Like letters of reference indicate like parts wherever such may occur in the
above figs, of drawings.
It may here be remarked that the engines heretofore employed in which is used
a hydrocarburet mixed with atmospheric air to produce the explosive gas and of
which the Prayton and Sterne engines are types have a separate air pump which
makes such machines very complicated and one of the objects of this invention is
to dispense with this separate air pump by utilizing the piston cylinder itself as an
air pump as will be presently described.
Referring to Figs. 1, 2, and 3 of the drawings F indicates the main frame
of any suitable form and material to support the mechanism that constitutes
the engine. C is the piston cylinder mounted vertically on the frame and con-
structed as usual in this class of machines with a water jacket J through
which a constant circulation, of cool water is established for well known and
obvious purposes.
The cylinder C is divided into two chambers fg by the piston P. The chamber g
here serves as an air compressing chamber and the piston P is employed for
compressing the air therein at each upward stroke and sucking fresh air at
each downward stroke. This chamber is in communication with a compressed
àir reservoir R by means of the piper and passages c c¹ formed in the upper
head C of the cylinder.
In the latter is formed a second passage c¹ through which air is admitted to
chamber which air after being compressed escapes into the reservoir R through
channels c c. In the channel c¹ is located a suction valve the rod of which
projects some distance above the head of the cylinder and through a stationary
guide arm n below which the valve rod carries a nut or stop that abuts on the
under side of said arm when the valve has reached its seat. At its upper end the
valve rod carries a thumb nut n¹ and between the latter and the guide n a coil
spring the tension of which tends to hold the valve to its seat in the head of the
cylinder. By means of the thumb nut n¹ the valve is made adjustable so as to
more or less open the air inlet port by more or less compressing the coil spring and
thereby increasing or decreasing its tension and power exerted upon the valve and
rod as will be readily understood. In the channel c is located an escape valve vi
the valve rod of which carries a coiled spring the tension of which tends to hold
the valve down to its seat until moved by the pressure of the air within the
cylinder chamber g. The chamber f of the cylinder C is in communication with
the vaporizing or atomizing appliances through passage f' and with the outer
atmosphere through passage fll and pipe 1; each channel is provided with a stop
cock, or valve namely the channel f¹ with an admission valve z and the channel fi
with an exhaust valve z¹ or other equivalent appliances whereby the communication
between the cylinder chamber ƒ may be established with and shut off from the
atomizer and outer atmosphere.
A portion of the compressed air passes from the reservoir R to the atomizer by
pipes where such air combines and is saturated with the fine spray or vapor
of the liquid used to produce the explosive gas and carried along with the air to
a chamber provided with a perforated diaphragm where the current meets with
a second current of air direct from the reservoir and pipe K and both currents pass
from said chamber to the cylinder chamber of through passage f¹. The pipes k
and are provided with stop-cocks m m² respectively to regulate the volume of
air admitted to the atomizer and chamber k"-A is the main crank shaft that

page_text: carries the two fly wheels S and with the cranks of said shaft is connected one end
of the connecting rods P P the other end being connected with the cross head T
with which the piston rod e is connected said cross head travelling as usual in a
suitable guide frame F¹.
Upon the crank shaft A are mounted two cams t t the former actuating the
admission valve or stop cock z and the latter the exhaust valve or stop cock z¹
above referred to. The shaft A also carries a belt pulley 8, and a grooved pulley N
the former actuating the magneto-electric generator and the latter the atomizing
apparatus. The admission and exhaust valves z z¹ are connected by means of
articulated levers H H¹ to the cams t t¹ and their extremities carry an antifriction
roller a a¹ respectively that ride in the cam groove, or track or over the cain
surface by which said levers are moved to open or close the admission and exhaust
valves. The form of these cams is shown in Fig. 6 and in Fig.
is shown a con-
struction of cam provided with a cam track. These cams are mounted upon the
crank shaft in such relation to each other that when the piston has reached or is
about to reach the limit of its stroke in one direction the admission valve is opened,
and the exhaust valve closed and when the said piston has reached or is about to
reach the limit of its stroke in a reverse direction the exhaust valve is opened and
the admission valve closed as will be readily understood.
Having now described the general construction of the improved engine it will
be understood that any suitable mechanism or appliances may be employed for
atomizing or vaporizing the liquid employed to produce the explosive gas and that
any suitable means may be employed for igniting the explosive gas within the
cylinder chamber f to drive the piston in one direction (the centrifugal force of the
fly wheels carrying the piston in a reverse direction)
By his experiments however Mr Marcus has found on the one hand that the
small injectors as in the Hock engine for instance for atomizing the liquid or
injecting the vapors leave much to be desired so far as their effectiveness is
concerned, the work performed by these devices being imperfect.
On the other the method heretofore resorted to to ignite that is explode the
gases or vapours by means of an electric spark produced from a so called Kuhmkorff
apparatus in combination with galvanic elements (Lenon's system) presents
as is well known great inconveniences that induced Mr Marcus as early as 1872 to
devise means which would be more perfect in their operation more reliable, more
convenient and simpler in construction, and especially to devise means, whereby
an electric current inay be produced without the use of a battery, by means of
magnetic inductors operated by the engine itself, and he has at last succeeded in
obtaining not only a vaporizer or more properly an atomizer of great effectiveness,
and very simple in construction but also a magneto-electric generator of equally
simple construction of great effectiveness and reliability which will be now described
in their order.
Referring to Figs 7, 8, 9 and 10 the latter two figures showing a slight modifi-
cation in the arrangement of the atomizing brushes. Q is a vessel of suitable
construction in .communication with a feed reservoir through pipe q the relative
position between the two is preferably such that the level of the liquid in Q will
never rise much beyond the centre of the shaft b. The latter is mounted in suitable
bearings and carries a brush wheel to which a continuous rotation in the direction
of the arrows or an intermittent rotation or an oscillatory movement may be
imparted from the engine mechanism.
As shown the brush wheel has a continuous rotation imparted thereto from the
pulley N on the crank shaft A and the pulley N¹ on the brush wheel shaft b
through the medium of a belt or cord-As the brushes are passing through the
liquid they take up a certain quantity thereof and then come in contact with a
scraper or shield d whereby any excess of liquid is removed from the brushes
which afterwards come in contact with the adjustable atomizing plate d' where
the remaining liquid adhering to the brushes is atomized, and where the compressed
air coming from reservoir R through pipe k' is mixed with the atomized liquid and

page_text: carried out of the apparatus through pipe e¹ into the chamber
above described to the cylinder chamber f.
and thence as
In Figs 9 and 10 are shown the atomizing brushes mounted on an endless belt /¹
travelling over belt pulleys 6' 61 supported in suitable bearings, otherwise the
operation and construction of the atomizer is the same as those of the one just
described.
Instead of causing the brush belt to travel in a vertical direction said belt may
be caused to travel in a horizontal direction and the construction and arrangement
of these appliances will to some extent depend upon the size of the engine
arrangement of its cylinder and the space where the engine is located.
Having described the atomizer, we will now describe the magneto-electric
generator referring more particularly to Figs. 11, 12, 13 and 14.
B and B are two metallic (iron) segments that form the two poles of a powerful
magnetic reservoir or magazine Z which latter is composed of a series of bar
magnets oo o et cetera and the metallic framing O to which said bar magnets are
screwed. The pole segments B B' are attached to a square plate O¹ of a material
not influenced by magnetism and which serves as a support and cover for the same.
As shown by Fig 13 the bar magnets o are arranged radially upon the pole
segments and in two groups of an equal number opposite each other. Between the
pole segments is located the induction coil g' and its armature f¹, f², f³ mounted
upon a two part shaft D D' The armature is composed of a metallic core f³ and
two metallic discs, f¹, f2 (of soft iron or other suitable metal). The coil g¹ is
composed of a bobbin of a suitable isolating substance mounted on the core f³ and
upon which is wound the insulated copper wire one end of which coil is connected
with the metallic part of the apparatus and the other with a sleeve h mounted
upon part D of the two part shaft and from which it is insulated.
The latter part of this shaft has its bearings in the framing O and a plate ¹ and
the part D¹ of said shaft has its bearings in a plate i and the plate o' said
plates being secured to the armature f¹ f2 and serve to connect the shaft
therewith. The plate o' carries a binding screw h', isolated from each other said
screw being in metallic connection with the sleeve h through the metallic bar n¹¹
and the contact spring h".
Upon the part D of the shaft within the framing or supporting plate O is
mounted a slotted lever g which is actuated or carried along by the pin or stud 711
secured to a belt pulley s¹ mounted upon a short shaft D" that has its bearing in
the metallic framing O said shaft having its bearings eccentric to those of
shaft D D and is rotated from the engine through belt pulley s on main crank
shaft A.
By means of this arrangement a differential speed is imparted to the shaft D D¹
and induction coil.
The uniform rotation of the pulleys & s¹ is of great importance and may be
effected in any desired manner and by any of the well known means. To effect
this Mr Marcus has as shown in fig. 14 constructed the belt pulleys & 8¹ with
peripheral recesses, and the belt y with projections or teeth that engage the
recesses and thus uniformly rotate the pulleys and prevent any slip of the belt y.
By the above described construction and extension of the poles of the magnetic
'magazine over the entire width of the pole segments, on the one hand and
especially the application of the lever movement to rotate the induction coil on the
other hand the armature is exposed sufficiently long to the magnetic influence of
the bar magnets as to secure a complete and thorough magnetization thereof while
the change in polarity follows very rapidly.
Upon a standard F11 secured to the plate O¹ of the magneto-electric generator is
secured an angular or two armed lever x x¹ and upon the part D¹ of the two part
shaft of said generator is mounted a cam u upon which rides the extremity of the
arm x of lever xx¹ which extremity may be provided with an antifriction roller
for obvious purposes.
The arm of lever x x carries a metallic pin y¹ that
penetrates into the enlarged portion of the exhaust passage f" of the cylinder

page_text: :
chamber fimmediately in front of the stop-cock or exhaust valve. The pin
moves gas tight within the aperture through which it passes and carries a coiled
spring the tension of which tends to force the lever arm and pin outward from the
passage f A second pin y¹¹ projects some distance into the passage ƒ" and upon
the same plane as the pin y. the poles of the induction coil being connected with
said pins by wires n n through the binding screw h¹ and the metallic portion of
the generator. As plainly shown in fig. 14 each pin y, y¹¹ terminates in an
enlargement or contact point or button. As the cam u rotates the arm x' of lever
xx is slowly moved inward when the roller moves up the incline of the cam, and
when at its highest point or greatest distance from the centre of the cam the
contact point of pin y¹ will be in contact with the contact point of pin y" and
immediately thereafter the extremity of the lever arni x¹ will drop over the nose
of the cam u and the contact of the two pins will be interrupted. The sudden
interruption of the contact between the contact points produces the spark that
ignites and explodes the gas in chamber f Thus it will be seen that at each
revolution of the cam u the gas is exploded and the piston P moved outward of
the cylinder C.
By the mechanism hereinafter described a differential motion is imparted to the
induction coil and its shaft and the object of imparting such a movement to the
coil and shaft will be apparent for the reason that it is necessary that the coil
during a portion of its rotation should be moved sufficiently slow to insure its
thorough magnetization in order to obtain the necessary current strength to
produce the spark and it should be moved sufficiently fast to brake the current as
suddenly as possible in order to produce the spark to ignite and explode the gases:
And as will be readily understood the cam u will be mounted upon its shaft as to
cause the separation of the contact pins at the proper time hence said cam is
operated from and timed by the movements of the piston through the piston
driven shaft.
.:
The movements of the cam shaft D' the cam u and the lever x x¹ are so timed
relatively to the movements of the piston and gas inlet valve that when said
piston has reached or is about to reach the limit of its inward motion or after
starting on its outward motion and immediately before or a little after the inlet
valve has been closed, the pins y¹ and y¹¹ will be in contact to close the induced
electric circuit and when said inlet valve is closed the contact will be suddenly
broken as described thereby producing the electric spark to ignite and explode the
explosive gas within chamber f and again move the piston outward.
It will be understood that instead of using a vertical cylinder the engine may
be constructed for use with an inclined or a horizontal cylinder the latter
construction being shown in figs 4 & 5. The head of the cylinder being removed
it is in 'all respects the same as the engine herein before described except as regards
such modifications in the construction and arrangement of the parts as are
necessary with the altered position of the cylinder and if desired a separate air
compressor may be employed or it may be operated without air-compressing
mechanism in which case the outer end of the cylinder may be open.
And if instead of a mixture of a hydro-carburet and atmospheric air curburetted
hydrogen or other explosive gas is used then the atomizer may be dispensed with
as will be readily understood. As shown in figs. 4 & 5 the cylinder C is open at
one end the engine being constructed for operation without compressed air.
A further modification in the construction of this engine lies in the fact that a
cross head and guide rods are here dispensed with which makes the engine more
compact.
The piston rod is directly connected with an angular lever or walking beam W
that operates the crank shaft A through the medium of a connecting rod P¹ In
this construction the inlet and outlet valves or stop-cocks z z' are operated by
means of two cams t t¹ respectively mounted on the main crank shaft A and by
means of articulated levers H H¹ each composed of three lever arms h' h² h³ as
plainly shown the track of the cams t't' being so formed that at each revolution of

page_text: the crank shaft the valves 21 are alternately closed and opened and in such
manner that when the admission valve is open the escape valve is closed, and vice
versa as will be readily understood.
The operation of the engine is as follows: To start the engine a partial rotation
is imparted to the crank shaft whereby the atomizer is set in operation and
compressed atmospheric air from the reservoir R admitted to and mixed with the
vapors employed to produce the explosive gas and simultaneously therewith the
admission valve z is opened. The piston P at the same time moves outward
drawing the explosive gas into chamber f. The magneto-electric generator is also
set in motion and the contact or fixing pins y¹ y" brought into contact through
the medium of the slotted lever q¹ pin 1 and belt pulleys s s¹.
By the continual rotation of the crank shaft the admission valve is closed and
the contact between the pins y¹ y suddenly interrupted the gas admitted is
ignited and exploded which moves the piston outward to the end of its stroke.
The air in chamber is compressed and passes into the receiver R and the escape
valve is opened to allow the gases to escape from chamber f and the piston moves
back drawing air from without through suction valve v. The power of the piston
is transmitted through the cross head to the connecting rods p p and through
them to the crank shaft A.
