Improvements in Internal Combustion Engines.
We, GEORG HIRT, of 10, Troststrasse, Nuremberg, in the Empire of Germany,
Overlooker, and GEORG HORN, of 15, Anssere Sutzbacherstrasse, Nuremberg
aforesaid, Mechanic, do hereby declare the nature of this invention to be as
follows:-
1
This invention relates to improvements in internal combustion engines of
the class wherein the hollow piston of the engine encloses the explosive mixture
and brings it to the ignition flame or tube where it is allowed to escape, the
object of the invention being by the arrangement and combination of a second
or supplementary piston to suck or draw in the explosive mixture into the
piston and there to confine it until the piston reaches the dead position at the
upper part of the cylinder.
In the accompanying drawing a sectional view of a cylinder constructed
according to this invention is shewn.
According to this invention the piston 1 of the engine encloses a second
piston 2 moving in the former. When the piston 1 is in the position shewn
in the drawing the piston 2 is moved downwards and sucks or draws explosive
mixture into the chamber 3 through the opening 4 of the cylinder and the
opening 5 of the piston 1. When the piston 1 moves towards the upper part
of the cylinder the piston 2 also moves upwards, thus imprisoning or confining
the mixture in the chamber 3. When the piston 1 has attained its upper
dead position the opening 5 will come opposite the port 6 in the cylinder com-
municating with the ignition tube or flame the piston 2 forcing out the hereto-
fore confined mixture through the two openings when completing the upper
portion of the stroke at the upper end of the channel 3. At 7 is the exhaust
port.

Improvements in Internal Combustion Engines.
We, GEORG HIRT, of 10, Troststrasse, Nuremberg, in the Empire of Germany,
Overlooker, and GEORG HORN, of 15, Anssere Sutzbacherstrasse, Nuremberg
aforesaid, Mechanic, 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 improvements in internal combustion engines of

the class wherein the hollow piston of the engine encloses the explosive mixture
and brings it to the ignition flame or tube where it is allowed to escape, the
object of the invention being by the arrangement and combination of a second
or supplementary pistón to suck or draw in the explosive mixture into the
piston and there to confine it until the piston reaches the dead position at the
upper part of the cylinder.
Such being the nature and object of our said invention the following is a
complete description of same, reference being had to the accompanying draw-
ing which is a sectional view of a cylinder constructed according to this
invention.
According to this invention the piston 1 of the engine encloses a second
piston 2 moving in the former. When the piston 1 is in the position shewn
in the drawing the piston 2 is moved downwards and sucks or draws explosive
mixture into the chamber 3 through the opening 4 of the cylinder and the
opening 5 of the piston 1. When the piston 1 moves towards the upper part
of the cylinder the piston 2 also moves upwards thus imprisoning or confining
the mixture in. the chamber 3. When the piston 1 has attained its upper
dead position the opening 5 will come opposite the port 6 in the cylinder com-
municating with the ignition tube or flame, the piston 2 forcing out the hereto-
fore confined mixture through the two openings when completing the upper
portion of the stroke at the upper end of the chamber 3. At 7 is the exhaust
port.
Having nowparticularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is: -
In 'internal combustion
engines a secondary piston inside a hollow ordinary
piston as and for the purpose herein described and substantially as illustrated
by the annexed drawing.
