PROVISIONAL SPECIFICATION.
An Improved Mode and Mechanism for Regulation of the
Temperature of the Combustion Chamber and Vaporizer in
Petroleum Motors.
I, EMIL CAPITAINE of Ischacherschestrasse 62, Leipzig-Plagwitz, in the
Empire of Germany, Engineer, do hereby declare the nature of this invention to
be as follows:-
It is of great advantage if the temperature of the walls of the combustion
chamber and vaporizer in petroleum motors is kept constant. There exist petroleum
motors in which the petroleum is vaporized in the uncooled hot combustion chamber
and others in which the combustion chamber is cooled with water and the petroleum
is vaporized in a special vaporizer heated from the outside. The present invention
for the regulation of the temperature is applicable to the walls of the combustion
chamber as well as to the special vaporizer.
In the annexed drawing is shown the new construction. Fig. 1 being an
elevational section, Fig. 2 a plan partly in section.
A is a small hollow space filled with metal or a combination of metals. This
space is in the wall of the uncooled combustion chamber or the vaporizer and
heated from the outside the temperature of which can be regulated. According to
the temperature which it is required to maintain and not surpass, a metal or a
combination of metals is used which at a certain degree of the temperature is more
or less fusible; B is a bar or shaft the ends of which may have any form and which
is put in the metal or the combination of metals. In the drawing the end is bent
to augment the resistance when the metal or combination of metals becomes hard.
In every case a mechanical force is constantly operating which tries always to move
the bar B in the vessel. The kind of movement corresponds to the construction or
arrangement of the temperature regulator. Here the movement of the bar B is
oscillatory as well as rotary. The bar B lies in the collar C. The collar C being
fixed in a manner suitable to the local requirements. On the upper part of the
bar B is fixed a round disc D which serves as a pulley when the bar B has to rotate.
Also a solid arm E is fixed on the disc D in case the bar B is to be moved only
to and fro. In the latter case the bar F is moved to and fro and presses against the
lever arm E, whilst a spring G pulls against the lever arm E. With the pin a is
connected either the piston X of a pump L by a bar S or with the said bar S is
connected a slide M or valve.
Supposing that the pump is connected to the pin a and that the arm E with its
spring G and its bar F do not exist the disc D is rotated by a strap or cord o the
pump L presses air or liquid through the tube z behind the piston n movable in
the cylinder N. The piston is thus pushed downwards and the valve V or a slide
or other closing device is either closed or opened.
As soon as the combination of metals melts in the vessel A the bar B can be
turned. The movement of the bar by means of the strap or cord c is operated by
the motor. The pump L pumps air or water behind the piston n until the piston
bas opened the valve. After this the pump.can continue to pump a little and only
as much as cau pass through the small opening i. As by the opening of the valve

page_text: cold air or water enters the uncooled combustion room or vaporizer the metal or
the combination of metals will begin to congeal. Now the congealing metal offers
to the bar B so much resistance that the strap o cannot continue to turn the disc D
and the strap will slide thereon. The piston X of the pump L will stop in its
movement and the spring P press back the piston whereby the contents of the
cylinder N escape slowly through the opening i and the valve V is closed again.
After this a rewarming of the combustion chamber or of the vaporizer takes place
until the temperature is again reached which is not to be surpassed.
Suppose now that the pump piston X is not connected with the pin a and also
that there is no operation of the disc D by the strap o, then the slide M is brought
into connection with the pin a and the bar F is continuously moved to and fro and
operates on the lever arm E. While the combination of metals in the vessel A. is
liquid the bar F presses the arm E to the left and on the going back of the bar the
spring G will pull the arm E to the right thus the slide M closes and opens
alternately and lets in sliort interruptions of cold air or water which pass to the
heated combustion chamber or vaporizer. But as soon as the combination of
metals begins to congeal slowly the combination enters into an intermediate state
(it becomes pulpy) and in this pulpy condition the spring G will be no more able
to move back the arm and in this manner the arm E remains finally at rest in its
normal position the slide M being in a closed position.
Also during the movement of the bar a bell may be rung by the knocking of a
clapper connected to the bar.

An Improved Mode and Mechanism for Regulation of the
Temperature of the Combustion Chamber and Vaporizer in
Petroleum Motors.
I, EMIL CAPITAINE, of Ischacherschestrasse 62, Leipzig-Plagwitz, Germany,
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 :-
It is of great advantage if the temperature of the walls of the combustion chamber
and vaporizer in petroleum motors is kept constant. There exist petroleum motors
in which the petroleum is vaporized in the uncooled hot combustion chamber, and
others, in which the combustion chamber is cooled with water and the petroleum
is vaporized in a special vaporizer heated from the outside. The present invention
for the regulation of the temperature is applicable to the walls of the combustion
chamber as well as to the special vaporizer.
In the drawing filed with my Provisional Specification is shown the new
construction. Fig. 1 being an elevational section, Fig. 2 a plan partly in section..
A is a small hollow space filled with metal or a combination of metals. This
space is in the wall of the uncooled combustion chamber or the vaporizer and
heated from the outside, the temperature of which can be regulated.. According
to the temperature which it is required to maintain and not surpass, a metal or a
combination of metals is used which at a certain degree of temperature is more or
less fusible. B is a bar or shaft, the ends of which may have any form and which

page_text: is put in the metal or the combination of metals. In the drawing, the end is bent to
augment the resistance when the metal or the combination of metals becomes hard.
In every case a mechanical force is constantly operating which tries always to move-
the bar B in the vessel. The kind of movement corresponds to the construction
or arrangement of the temperature regulator. Here the movement of the bar B is.
oscillatory as well as rotary. The bar B lies in the collar C. The collar C being-
fixed in a manner suitable to the local requirements. On the upper part of the
bar B is fixed a round dise D, which serves as a pulley, when the bar B has to
rotate. Also a solid arm E is fixed on the disc D in case the bar B is to be moved
only to and fro. In the latter case the bar F is moved to and fro and presses
against the lever arm E whilst a spring G pulls against the lever arm E.
With the pin a is connected either the piston X of a pump L by a bar S or with.
the said bar S is connected a slide M or valve.
Supposing that the pump is connected to the pin a and that the arm E with its.
spring G and bar F do not exist; the dise D is rotated by a strap or cord o, the
pump L presses air or liquid through the tube z behind the piston n movable in the
cylinder N. The piston is thus pushed downwards and the valve V or a slide or-
other closing device is either closed or opened.
As soon as the combination of metals melts in the vessel A, the bar B can be.
turned. The movement of the bar by means of the strap or cord o is operated by
the motor. The pump L pumps air or water behind the piston n, until the piston
has opened the valve. After this the pump can continue to pump a little and only
as much as can pass through the small opening i. As by the opening of the valve
cold air or water enters the uncooled combustion room or vaporizer the metal or
the combination of metals will begin to congeal. Now the congealing metal offers
to the bar B so much resistance that the strap o cannot continue to turn the disc D
and the strap will slide thereon. The piston X of the pump L will stop in its.
movement and the spring P press back the piston, whereby the contents of the
cylinder N escape slowly through the opening and the valve V is closed again..
After this a re-warming of the combustion chamber or of the vaporizer takes place,.
until the temperature is again reached which is not to be surpassed.
Suppose now that the pump piston X is not connected with the pin a, and also.
that there is no operation of the disc D by the strap o. Then the slide M is
brought into connection with the pin a and the bar F is continuously moved to and
fro and operates on the lever arm E. While the combination of the metals in the
vessel A is liquid, the bar F presses the arm E to the left and on the going back of
the bar the spring G will pull the arm E to the right thus the slide M closes and
opens alternately and lets in short interruptions of cold air or water which pass to
the heated combustion chamber or vaporizer. But as soon as the combination of
metals begins to congeal slowly, the combination enters in an intermediate state (it
becomes pulpy) and in this pulpy condition the spring G will be no more able to
move back the arm and in this manner the arm E remains finally at rest in its
normal position the slide M being in a closed position.
Also during the movement of the bar a bell may be rung by the knocking of a
clapper connected to the bar.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manuer the same is to be performed I declare that what I
claim is :-
The mode of regulating the temperature of the uncooled combustion chamber or
vaporizer of petroleum motors consisting in the arrangement of a hollow space or
vessel in the combustion chamber or vaporizer filled with a metal or a combination
of metals, the melting point of which is at the temperature, which the heating may
not surpass, and of a solid body which is put in the metal or the combination of
metals and provided with a valve for the passage of a cooling medium, which is
stopped in its movement, the valve remaining closed, when the metals are not liquid..

page_text: but capable of movement so that the valve can be opened, as soon as the metals are
liquid, in which latter case the valve permits the entrance of cold air or water to
the walls of the combustion chamber or vaporizer.
