Improvements in or relating to Internal Combustion Engines.
I, NICOLAS VINCKE, of 78, Rue Leopold, Malines, Belgium, Engineer, do
hereby declare the nature of this invention to be as follows:-
This invention relates to an internal combustion engine with two cylinders,
four stroke, adapted to be used as a stationary motor or for motor-cars, vessels etc.
and occupying very little space in comparison with the power developed, and
characterised by the automatic working of its inlet valves, the simple and adjust,
able working of its exhaust valve and the protection as well as continuous
lubrication of its frictional parts.
The motor consists of two cylinders cast together and surrounded by a cooling
jacket. At the bottom the cylinders are supported on a hollow cast iron frame
serving at the same time as a protective casing for the moving parts (connecting
rod, crank etc.). This casing is provided at the bottom with brackets serving to
secure it to the foundation plate. Said brackets may be cast or formed about
the middle of the height of the cylinders or in other position according to require-
ments. A curved or other shaped trough completes the frame at the bottom and
is filled with oil so that the above mentioned moving parts are constantly immersed
in the oil, and are also protected against dust and foreign matter.
At the top the cylinders and their casing are connected, by means of a joint, to a
chamber constituting the explosion chamber and having cast on it valve chests
for the inlet and exhaust valves, as well as a passage through which ignition takes
place. The arrangement of this chamber constitutes one of the characteristic
features of the new motor. It enables the latter to be constructed with only one
joint.
On the chamber are cast valve chests or the inlet valves and the exhaust valves
respectively. The explosive mixture from a carburettor or other source of supply
through a tube enters each inlet valve chest and during the suction period presses
the valve down in order to enter the explosion chamber. The spindle of the inlet
valve guided by a projection cast on the chamber, is provided at its outer end
with a shoulder between which and the projection a helical spring is placed whereby
the valve is returned to its seat, as soon as the suction ceases.
Each of the exhaust valves has a spindle guided vertically and provided with a
shoulder against which presses a helical spring which returns the valve to its
seat when the mechanism operating the valve ceases to act. This mechanism
consists of a cam on an intermediate shaft receiving its motion from the crank shaft
through toothed gearing. A vertical spindle or rod guided in a socket or sleeve
secured to the cylinder bears at one end against the valve spindle and carries at its
other end a roller engaging with the surface of the cam. The projections on the
latter cause the rod to be raised, and consequently also the valve spindle and the
valve. A helical spring arranged in the socket always presses the rod towards the
cam, so that the roller is constantly in engagement with the cam. The exhaust
takes place through a branch pipe.

page_text: Each of the cylinders is provided with it own set of valves, the exhaust valves
being operated by two cams secured to the same intermediate shaft.
The cams can be moved say, by means of a lever, in order to regulate the degree
of compression. To start the engine, the cams are moved so as to decrease com-
pression.
The ignition may be effected either by incandescence or by an electric spark, or
in other suitable manner.

Improvements in or relating to Internal Combustion Engines.
I, NICOLAS VINCKE, of 78, Rue Leopold, Malines, Belgium, 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:-
The invention relates to internal combustion engines with two cylinders, four
stroke, adapted to be used as a stationary motor or for motor-cars, vessels etc.
occupying very little space in comparison with the power developed, and
characterised by the automatic working of its inlet valves, the simple and adjustable
working of its exhaust valve, and the protection as well as continuous lubrication
of its frictional parts.
The accompanying drawing illustrates, by way of example, one construction of
engine according to this invention,
Fig. 1 is an elevation, partly in vertical section through the crankshaft of the
motor.
Fig. 2 is a vertical cross section in a plane normal to the crank shaft.
The motor consists of two cylinders cast together and surrounded by a cooling
jacket E. At the bottom, the cylinders are supported on a hollow cast iron
frame M serving at the same time as a protective casing for the moving parts
(connecting rod, crank etc.). This casing is provided at the bottom with brackets P
serving to secure it to the foundation plate. Said brackets may be cast or formed
about the middle of the height of the cylinders, or in other position according to
requirements. A curved or other shaped trough N. completes the frame at the
bottom and is filled with oil so that the above mentioned moving parts are
constantly immersed in the oil, and are also protected against dust and foreign
matter.
At the top, the cylinders and their casing are connected, by means of a joint, to a
chamber constituting the explosion chamber, and having, cast on it, valve chests
for the inlet and exhaust valves, as well as passage o through which ignition takes
place. The arrangement of this chamber constitutes one of the characteristic
features of the new motor. It enables the latter to be constructed with only
one joint.
On the chamber are cast valve-chests S S¹ for the inlet valves the exhaust valves
respectively. The explosive mixture, from a carburetter or other source of supply,
through a tube (D), enters each inlet valve chest S¹, and during the suction period
presses the valve down, in order to enter the explosion chamber. The spindle F¹
of the inlet valve S¹, guided by a projection cast on the chamber, is provided at its
outer end with a shoulder between which and the projection a helical spring R¹
is placed, whereby the valve S¹ is returned to its seat, as soon as the suction
ceases.

page_text: Each of the exhaust valves S has a spindle F guided vertically and provided
with a shoulder against which presses a helical spring R, which returns the valve
to its seat when the mechanism operating the valve ceases to act. This mechanism
consists of a cam L on an intermediate shaft receiving its motion from the crank
shaft, through toothed gearing A1 A2 A3, shown in dotted lines in Fig. 2. A
vertical spindle or rod H, guided in a socket or sleeve I secured to the
cylinder, bears at one end against the valve spindle F and carries at
its other end a roller J engaging with the surface of the cam. The projections
on the latter cause the rod H to be raised, and consequently also the valve spindle
and the valve S. A helical spring r arranged in the socket I, always presses the
rod H towards the cam, so that the roller is constantly in engagement with the
cam. The exhaust takes place through a branch pipe W.
Each of the cylinders is provided with its own set of valves, the exhaust valves
being operated by two cams secured to the same intermediate shaft K.
The cams can be moved say by means of a lever in order to regulate the degree
of compression. To start the engine, the cams are moved so as to decrease
compression.
The ignition may be effected either by incandescence or by an electric spark,
or in other suitable manner.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. A four-stroke two-cylinder engine adapted to be used as a stationary engine
or for motor cars, vessels or other purposes, the mechanism of which is protected by
a casing forming the frame and constantly dips into oil in the casing and
characterised by all the valves being arranged on the rear-chamber, so that the
motor is constructed with only a single joint; or by the automatic working of
valves for the admission of the explosive mixture, and by the working of the
exhaust valves by rods and cams.
2. In an engine of the character described, the arrangement of the rear chamber
of the cylinders constituting the explosion chamber, carrying the valve chests and
connected by a joint to the upper portion of the cylinders.
3. In an engine of the character described, the arrangement of valves for the
admission of the explosive mixture, automatically opening during the suction
period substantially as described.
4. In an engine of the character described the arrangement of the exhaust
valves operated by two cams secured to an intermediate shaft and rods with
return springs between the cams and valve spindles the compression being regulated
by the lateral adjustment of said cams.
5. In an engine of the character described the arrangement of a frame serving
as a protecting casing for the moving parts and of a lower trough forming an oil
bath for said parts substantially as described.
6. The combination and arrangement of parts constituting the complete engine
substantially as described and illustrated in the accompanying drawings.
