PROVISIONAL SPECIFICATION.
Improvements relating to Hydro-carbon Engines.
HUGO WEGELIN, of Augsburg, in the Empire of Germany, Engineer, do
hereby declare the nature of this invention to be as follows:-
My invention relates to hydro-carbon engines and has for its object to provide
effective means for the regulation of the admixture of the explosive charge.
My invention is more particularly applicable for the regulation of the propor-
tion of an explosive charge of hydro-carbon vapour and air so that the exact pro-
portion of vapour and air may be made to secure effective combustion and to
regulate the power developed.
My invention consists of a regulating valve having two slots provided therein
which correspond with two ports provided in the casing in which the valve is
contained the one port being for the admission of air and the other for the
admission of vapour; the relative disposition of the slots and ports is such that
when the one port in the valvo casing is fully open the other shall be com-
pletely closed so that the ports may thereby be opened to any proportionate
extent required to secure either a rich or a poor mixture as the port for the
admission of vapour is opened to a small extent and the port for the admission
of air to a large extent, or vice versa.
In carrying my invention into effect in the provision of a regulating valve
for the regulation of the proportion of vapour and air I provide a valve of
cylindrical or cup shape having a flat bottom surface in which a segmental
slot is provided near its edge while a slot is provided of corresponding length
upon the circumference.
The valve is mounted within a cylindrical casing which is provided upon its
bottom surface with a slot or port through which the hydro-carbon vapour may
be drawn while a slot or port is provided in the circumference of the casing
through which air may pass upon such port being uncovered by the slot or
aperture in the valve. The slots and ports are so disposed that a small opening
of the port admitting vapour shall be accompanied by a large opening of the
port admitting air and vice versa; the one port being completely closed while
the other is fully open, and that half opened while the other is so.
The valve is provided with a handle and index finger which projects outwards
and is moved within a slot in the casing and upon the face of a scale by which
it can be seen the extent of opening of the respective ports from the position of
the finger on the scale. The interior of the valve becomes a mixing chamber,
closed by a cover applied to the casing, from which the mixed vapour and air may
he lead either downwardly through a central tube or through a pipe laterally
issuing to the cylinder.
The valve casing may be provided upon the upper part of a vapourising
chamber whence the vapour may be conveniently withdrawn and admitted into
the mixing chamber.
It will thus be seen that by the use of a valve in accordance with my inven-

page_text: tion it is possible to regulate any proportion of gas or vapour and air by the
operation of one handle."

I, HUGO WEGELIN, of Augsburg, in the Empire of 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:
My invention relates to hydro-carbon engines and has for its object to provide
effective means for the regulation of the admixture of the explosive charge.
My invention is more particularly applicable for the regulation of the propor-
tion of an explosive charge of hydro-carbon vapour and air so that the exact pro-
portion of vapour and air may be made to secure effective combustion and to
regulate the power developed.
My invention consists of a regulating valve having two slots provided therein
which correspond with two ports provided in the casing in which the valve is
contained; the one port being for the admission of air and the other for the
admission of vapour; the relative disposition of the slots and ports is such that
when the one port in the valve casing is fully open the other shall be com-
pletely closed so that the ports may thereby be opened to any proportionate
extent required to secure either a rich or a poor mixture as the port for the
admission of vapour is opened to a small extent and the port for the admission
of air to a large extent, or vice versa.
Figures 1 and 2 are respectively sectional side elevation and sectional plan of
a gas and air regulating valve provided according to the invention.
In carrying the invention into effect as illustrated in Figures 1 and 2 of the
accompanying drawings in the provision of a regulating valve 1 for the regula-
tion of the proportion of gas or vapour and air I provide the valve 1 of cylindrical
or cup shape having a flat bottom surface 2 in which a segmental slot 3 is pro-
vided near its edge while a slot 4 is provided of corresponding length upon the
circumference of such valve. The valve 1 is mounted within a cylindrical
casing 5 which is provided upon its bottom surface with a slot or port 6 through
which the hydrocarbon vapour may be drawn while a slot or port 7 is provided
in the circumference of the casing through which air may pass upon such port
being uncovered by the slot or aperture 4 in the valve 1. An air valve S is
provided which is pivoted at 9 and maintained upon its seat by the slight pressure
of a spring 10 held in position by a bridge-piece 11, such valve opening simply
on the suction stroke of the engine. The slots and ports 3 and 4 and 6 and 7
are so disposed that a small opening of the port 6 shall be accompanied by a large
opening of the port 7 admitting air and vice versa, the one port being com-
pletely closed while the other is fully open and that half open while the other is
also half open. The valve 1 is provided with a handle 12 and index finger which
is secured to the valve by means of the pin 21. A slot 122 being provided in
the cap or cover 13 screwed upon the casing 5 and a scale 14 is mounted upon the
lid or cover by which it can be seen the extent of opening the respective ports
from the position of the finger on the scale. The interior of the valve 1 becomes

page_text: a mixing chamber closed by the cover 13 applied to the casing 5 from which the
mixed gas or vapour and air may be led either downwardly through a central tube
or laterally through a pipe 15 issuing to the cylinder, a valve 16 being preferably
provided together with an operating hand lever 17 to regulate the admission of
the explosive mixture to the cylinder.
The valve casing 5 may be provided upon the upper part of the vapourising
chamber whence the vapour may be conveniently withdrawn and admitted into
the mixing chamber.
It will thus be seen that by the use of a valve in accordance with the invention
it is possible to regulate any proportion of gas or vapour and air by the operation
of one handle.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:-
1. In hydrocarbon engines a gas or vapour and air regulating valve constructed
as herein before described.
2. In hydrocarbon engines a gas or vapour and air regulating valve having two
slots provided therein which correspond with two ports provided in the casing in
which the valve is contained, the one port being for the admission of air and the
other for the admission of gas or vapour, the disposition of the slots being such
that when one is completely opened the other shall be completely closed, such
valve being provided with an index finger and scale by means of which the
extent of opening of the respective ports may be indicated substantially as herein-
before described.
