Improvements in Gas and Hydro-carbon-engines:
I, WILLY SECK of Oberursel near Frankfurt-on-Main, in the Empire of
Germany, Manufacturer, do hereby declare the nature of this invention to be as
follows: :-
My invention relates to an improved gas motor or hydro-carbon-engine, and the
object of my invention is to provide an engine of great simplicity of construction,
the working parts of which are so arranged to enable their being lodged in a closed
casing partially filled with oil and water, or other lubricating substance. I, thereby
not only obtain a great economy of space, but also a complete self-lubrication of
the working parts and further the improved engine of my invention offers the great
advantage that no injury can be done to any persons by the working parts, as they
are all enclosed in the casing.
In general, the working order of the gas or hydro-carbon-engine is the same as
that of other known constructions; the gas is supplied by a gas conduit, or by a
generator developing hydro-carbon vapours. The said gas or vapours are drawn
into the engine by the suction of a piston together with atmospheric air which
becomes mixed with the gas and the mixture is ignited by a flame; an exhaust
valve serves to discharge the products of combustion.
The principal new features of my invention consist, first, in the peculiar valve
motion operated by an eccentric mounted on the crank shaft of the machine ;
secondly, in the peculiar arrangement of the regulator controlling the valve motion;
and, thirdly, in the combination of the main parts of the engine with an enclosing
case containing a suitable lubricating fluid to effect a continuous automatic
lubrication, and also to prevent injury being done by the working mechanism to
any person who might approach the engine.
The valve motion consists of a set of gear wheels, two of which (one fast and
one loose) are mounted on the crank shaft of the machine, the crank of which shaft
operates the piston through which the suction of gas and air is performed: Parallel
to said crank shaft, a fixed stud or shaft is arranged in the machine which carries
two gear wheels secured to or made integral with each other, the said gear wheels
are loose on their stud and mesh with the two wheels on the crank shaft. The size
of the four wheels is so proportioned that the loose wheel on the crank shaft makes
only one revolution while the shaft makes two.
Secured or formed to the said loose wheel on the crank shaft is an eccentric,
which has a bearing against a roller or sheave connected by a rod to the exhaust
valve of the explosion chamber of the engine. By this means, the said exhaust
valve is normally lifted once during every two revolutions of the crank shaft, but
in the beginning of the operation, the said sheave or roller which controls the said
exhaust valve may be shifted in a manner to receive a lift by the eccentric during
each revolution of the crank shaft, in order to provide an escape for the mixture of
gas and air before the explosion.
The regulator may be of a known construction preferably a centrifugal regulator,
and its varying positions are transmitted to a system of rods by which a stop is
thrown into engagement with a notch or pin of the exhaust valve rod, whereby
the said valve rod and valve are temporarily lifted out of control of the eccentric
till the regulator has returned in to its normal position, whereby the engagement
of the stop and notch is released and the play of the valve set free to continue.

Improvements in Gas and Hydro-carbon-engines.
I, WILLY SECK of Oberursel near Frankfurt-on-Main in the Empire of
Germany, Manufacturer 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 improved gas motor or hydro-carbon-engine, and the
object of my invention is to provide an engine of great simplicity of construction,
the working parts of which are so arranged to enable their being lodged in a closed
casing partially filled with oil and water, or other lubricating substance. I, thereby,
not only obtain a great economy of space but also a complete self-lubrication of the
working parts, and further the improved engine of my invention offers the great
advantage that no injury can be done to any persons by the working parts, as they
are all enclosed in the casing.
In general, the working order of the gas or hydro-carbon-engine is the same as
that of other known constructions; the gas is supplied by a gas conduit, or by a
generator developing hydro-carbon vapours. The said gas or vapours are drawn
into the engine by the suction of a piston together with atmospheric air which
becomes mixed with the gas and the mixture is ignited by a flame; an exhaust
valve serves to discharge the products of co:nbustion.
In the accompanying drawings
Figure 1 is a longitudinal vertical section of a gas-motor constructed according
to my invention ;
Figure 2 is a cross section drawn across lines A-B C, D of Figure 1;
Figure 3 illustrates in longitudinal section and side elevation, the mechanism for
controlling the exhaust valve, drawn to an enlarged scale;
Figure 4 represents the mechanism by which the valve motion is controlled
according to the varying positions of the regulator; and
Figure 5 represents a gas generator of any known construction, designed to
replace the gas inlet valve, if the motor is to be worked by hydro-carbon oil, instead
of by gas.
In the drawings
a is a closed casing, within which the principal working parts of the machine are
arranged; bare top plates secured to the casing, which plates, when removed, give
admittance to the interior of the casing; c are journal boxes to receive the
bearings d of the shaft journals e, the bore of said boxes e may be slightly tapering,
according to the tapering shape of the bearings d, which, being cut in the direction
of their length, are forced against each other by the conical bore of the box c.
fis the connecting rod mounted on the crank of the shaft e and driving the
piston g within the cylinder of the machine; i is the top plate of said cylinder,
and the valve, through which gas and air are drawn into the cylinder by the
suction of the piston g. In hydro-carbon-motors, the said valve k is replaced by a
suitable gas generator, such as is shown in Figure 5, for supplying hydro-carbon
vapours and air to the cylinder h. is the heating pipe, and m the lamp for heating
the same, n the valve for the exhaust of the products of combustion, o the valve
rod, pa spring tending to close the valve n, q an extension of the valve rod o
serving to open the valve at suitable intervals under the control of the regulator, 4
as hereinafter described. 2 3 4 are four gear wheels for controlling the valve
motion, said wheels being shown in a larger scale in Figure 3. s is the regulator
of the machine; t a disc or wheel with a circular groove, said disc varying its
position according to the position of the governor s. uu u are a set of connecting
rods which transmit motion from the disc t to the parts controlling the exhaust 5
valve n, as more fully represented in Figure 4.

page_text: The exhaust valve n is controlled by a cam r secured to or integral with a
toothed wheel loosely mounted on the shaft e at the side of another toothed
wheel fixed firmly to the shaft. Said wheel gears into a toothed wheel r
loosely mounted on a fixed trunnion of the machine, and to the said wheel
another wheel is cast or secured, meshing with the loose wheel on the journale.
The size of the wheels 13 is so calculated that makes one revolution,
whilst the wheel r, fastened to the shaft e, makes two. A disc or sheare v is cast
in a piece with or secured to the said wheel carrying the main cam w, and
an auxiliary cam x. The main cam w serves to operate on the exhaust valve n,
while the auxiliary cam & is provided to lift the said exhaust valve only when the
motor is being started to allow part of the compressed gas and air to escape.
The said cams w and r, revolving with the wheel 3, bear against a sheave y,
carried by the extension 9 of the valve rod o. The said sheave y can be shifted on
its stem by means of a fork z, as shown in Figure 3, and, according to the position
of said sheave y, it will be struck either by the cam w alone, or by both cams wo
and during one revolution of the wheel and disc v. If both cams strike
sheave y, the exhaust valve n will be lifted twice during one revolution of the
wheel, and part of the compressed gas is permitted to escape before being
exploded.
The lift of the valve » is, further, under control of the governors through the
medium of the disc and connecting rods ¹³ ³, the controlling device acting in
the following manner :-
u¹ and u are double armed levers turning on suitable pivots and connected by
the rod . The free end of the lever or rod u¹ engages by means of a pin or anti-
friction roller in the groove of the disc t of the governor, causing the other arm of
said lever u¹ to swing in the direction opposite to that in which the disc t is shifted
by the governor s. The rod transmits the corresponding motion to the lever u³,
the free end of which carries an inclined surface which, when bearing against the
pawl u, forces the same into engagement with a notch formed on or secured to
the rod y, whereby said rod is prevented from being lowered by the pressure of the
spring p, and, as long as the said pawl a continues in engagement with the said
notch, the exhaust valve n is kept open and the downward stroke of the piston g
draws in no gas and air till the said valve n is closed again. Owing to the
momentum of the fly-wheel on the shaft e, the piston 9 will continue to work in
the cylinder till the speed of revolution has diminished so far as to allow the
governors to return into its normal position, thereby moving the disc t and
the levers u and u³ in the opposite direction and throwing the inclined face on u³
out of engagement with the pawl u'. The said pawl, being free, is drawn out of its
engagement with the notch by a spring, and the rods q and o are free to be forced
down by the spring p, whereby the valve is closed and the piston g draws into the
cylinder a fresh quantity of gas and air for explosion.
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-
1. In a gas or hydro-carbon-motor, the combination, with the crank shaft and
