PROVISIONAL SPECIFICATION.
Improvements in or connected with Hydrocarbon Motors.
I, WILLY SECK, of Oberwesel, in the Kingdom of Prussia, in the Empire of
Germany, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to an improvement in that class of motors in which petroleum.
or other suitable hydro-carbon-oil is vaporised and. the gas thereby generated is
mixed with a suitable quantity of atmospheric air and exploded at suitable intervals
to furnish the driving power.
The improvement has reference to an injector intended to replace in a motor of
the kind before mentioned the pump which has been hitherto employed for
supplying to the vaporiser or gas generator the petroleum or mineral oil, in
suitable quantities as required by the work performed by the motor. The feed of
the petroleum by means of a pump has not been reliable so far as the supply of
predetermined adjustable quantities is concerned; by means of this improved
injector which replaces the pump, a regular predetermined and adjustable supply
of the liquid fuel may be easily obtained.
The drawing in of the quantity of petroleum and air suitable for producing the
mixture which is to be exploded is according to this invention obtained by the
sucking action of the lift of the piston in such a manner that, by the arrangement
of a retaining valve, the downward stroke of the piston draws air or liquid fuel into
the generator.and through the latter into the cylinder.
In order by means of the said valve to allow of a certain, exactly determined
and adjustable quantity of petroleum being supplied, I employ by this invention the
following device-
Into a hollow chamber having one or more apertures which communicate with
the outside atmosphere, I screw a plug which has a central bore in line with a pipe
which leads into a tank or reservoir situated beneath it containing the petroleum
or other liquid fuel to be employed in working the motor. The front end of this
screw plug is tapered and penetrates into a channel which leads from the above
mentioned hollow chamber. to a valve which controls the supply to the generator.
The passage of air from the hollow chamber through the channel above named is
regulated by screwing the tapering end of the plug more or less deeply into the
channel. If the plug be screwed up so far as to entirely close the passage, no air
will be able to pass and petroleum alone will flow through the central passage of
the plug. But if the tapering end of the plug be not tightly screwed into the
above named passage, an annular space will be left around its conical point, through
which space more or less air flowing in through the apertures in the sides of the
chamber is drawn, the quantity of air depending on the position of the tapering
point of the plug within the passage which may be adjusted as required.
The quantity of air admitted determines the quantity of petroleum which is
raised by suction through a pipe coming from the reservoir. As the quantity of
air admitted may be adjusted in the manner described, the feed of petroleum may
also be exactly controlled.
In order to obtain a regular and reliable supply of petroleum by means of the
device above described, it is essential that the petroleum contained in the reservoir
should be maintained at a constant level. For this purpose, the reservoir before
mentioned is connected by means of a pipe with another reservoir, the pipe entering
at the bottom of both reservoirs. The second reservoir is tightly closed by a plug
or stopper through which a pipe passes reaching down almost to the bottom of the

page_text: reservoir, being immersed in the fluid therein contained. The lower end of this
pipe determines the level of the fluid which is to be maintained within the first
named reservoir. By opening a valve cock in the connecting pipe between the
reservoirs, the fluid from the second reservoir will flow into the first reservoir and
rise therein up to the level which corresponds with the horizontal plane of the lower
end of the pipe situated as described in the second reservoir. Whenever petroleum
is drawn from the first reservoir through the suction pipe, the level will rise again
to the same height, the quantity withdrawn being replaced from the second
reservoir.
This effect due to the pressure of the air, which, in the second reservoir is
hermetically closed by the stopper, only acts through the pipe passing through
the stopper upon the fluid beneath the pipe. If, for instance, this pipe terminates
at a distance of one inch from the bottom of the reservoir, the pressure of air
through the pipe will act only on a fluid column of one inch, whilst all the fluid
above this is exposed to no pressure, being shut off from the outside atmosphere.
As soon as petroleum is drawn off from the first reservoir through the suction
pipe, the level will begin to sink accordingly, and simultaneously the level in the
second reservoir will be lowered. Air is thereby drawn through the pipe leading
into this second reservoir into the fluid from which it rises into the space above the
fluid, and there serves to displace a corresponding quantity of fluid which escapes
through the connecting pipe into the first reservoir, thus adjusting the level in both
reservoirs:
.
It will be obvious that the means of regulating the quantity of air admitted or
drawn in together with the petroleum may be varied in divers ways, the aperture
or apertures for admitting air into the chamber may be controlled by a separate
screw plug instead of by that through which the petroleum pipe is passed. Or the
discharge end of the suction pipe or plug through which the petroleum is drawn
from the first tank and delivered to the generator may be controlled by means of a
screw valve in such a manner as to reduce the discharge of petroleum independently
of the discharge of air.

Improvements in or connected with Hydrocarbon Motors.
1, WILLY SECK of Oberwesel in the Kingdom of Prussia 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 improvement in that class of motors in which
petroleum or other suitable hydro-carbon-oil is vaporised and the gas thereby
generated is mixed with a suitable quantity of atmospheric air and exploded at
suitable intervals to furnish the driving power.
The improvement has reference to an injector intended to replace in a motor of
the kind before mentioned the pump which has been hitherto employed for supply-
ing to the vaporiser or gas generator the petroleum or mineral oil in suitable.
quantities as required by the work performed by the motor. The feed of the
petroleum by means of a pump has not been reliable so far as the supply of
predetermined adjustable quantities is concerned; by means of this improved
injector which replaces the pump, a regular predetermined and adjustable supply
of the liquid fuel may be easily obtained.
The drawing in of the quantity of petroleum and air suitable for producing
the mixture which is to be exploded is, according to this invention, obtained by

page_text: the sucking action of the lift of the piston in such a manner that, by the arrange-
ment of a retaining valve, the downward stroke of the piston draws air or liquid
fuel into the generator and through the latter into the cylinder.
In order, by means of the said valve, to allow of a certain, exactly determined
and adjustable quantity of petroleum being supplied, I employ the device illustrated
by the annexed drawings.
On this sheet of drawings:-

Figures 2, 3 and 4 are also sectional elevations of modifications, hereinafter
particularly described, of the valve portion of the entire apparatus.
"
Into a hollow chamber a, having one or more apertures d which communicate
with the outside, atmosphere, I screw a plug b, which has a central bore: in line
with a pipe f which leads into a tank or reservoir / situated beneath it containing
the petroleum or other liquid fuel to be employed in working the motor. The
front end of this screw plug bis tapered and penetrates into a channel c which
leads from the above mentioned hollow chamber a to a valve k which controls the
supply to the generator. The passage of air from the hollow chamber a through
the channel c above named is regulated by screwing the tapering end of the plug b
more or less deeply into the channel.c. If the plug be screwed up so far as to
entirely close the passage c, no air will be able to pass, and petroleum alone
will flow through the central passage of the plug. But, if the tapering end of
the plug b be not tightly screwed into the above named passage c, an annular
space will be left around its conical point, through which space more or less air
flowing in through the apertures d in the sides of the chamber is drawn, the quantity
of air depending on the position of the tapering point of the plug
passage, which may be adjusted as required.
within the
The quantity of air admitted determines the quantity of petroleum which is raised
by suction through a pipe f coming from the reservoir . As the quantity of air
admitted may be adjusted in the manner described, the feed of petroleum may also
be exactly controlled.
In order to obtain a regular and reliable supply of petroleum by means of the
device above described, it is essential that the petroleum contained in the reservoir h
should be maintained at a constant level. For this purpose, the reservoir / before
mentioned is connected, by means of a pipe g, with another reservoir, the pipe g
entering at the bottom of both reservoirs hh. The second reservoir is tightly
closed by a plug or stopper i through which a pipe 1 passes, reaching down almost
to the bottom of the reservoir h¹, being immersed in the fluid. therein contained.
The lower end of this pipe f¹ determines the level of the fluid which is to be main-
tained within the first named reservoir h. By opening a valve cock g' in the con
necting pipe 9 between the reservoirs, the fluid from the second reservoir h' will
flow into the first reservoir and rise therein up to the level which corresponds
with the horizontal plane of the lower end of the pipe situated as described in
the second reservoir . Whenever petroleum is drawn from the first reservoir h
through the suction pipe, the level will rise again to the same height, the quantity
withdrawn being replaced from the second reservoir, h³.
This effect is due to the pressure of the air, which, in the second reservoir h¹
hermetically closed by the stopper i, only acts through the pipe f¹ passing through
the stopper upon the fluid beneath the pipe. If, for instance, this pipe terminates
at a distance of one inch from the bottom of the reservoir h', the pressure of air
through the pipe f¹ will act only on a fluid column of one inch, whilst all the
fluid above this is exposed to no pressure, being shut off from the outside
atmosphere.
As soon as petroleum is drawn off from the first reservoir through the suction
pipe f; the level will begin to sink accordingly, and, simultaneously, the level.in
the second reservoir will be lowered. Air is thereby drawn through the pipe f
leading into this second reservoir into the fluid from whence it rises into the space
above the fluid and there serves to displace a corresponding quantity of fluid which

page_text: g
escapes through the connecting pipe 9 into the first reservoir h, thus adjusting the
level in both reservoirs h and h'.
It will be obvious that the means of regulating the quantity of air admitted or
drawn in together with the petroleum may be varied in divers ways, the aperture
or apertures d for admitting air into the chamber a may be controlled by a separate
screw plug instead of by that through which the petroleum pipe is passed
(Figures 2 and 3). Or the discharge end of the suction pipe for plug 6 through
which the petroleum is drawn from the first tank and delivered to the generator
may be controlled by means of a screw valve, in such a manner. as to reduce the
discharge of petroleum independently of the discharge of air (Figures 4 and 5).
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
1. In a hydro-carbon-motor the combination, with a piston for drawing in liquid
fuel and air, of a chamber through which the hydro-carbon oil and air are drawn
before entering the gas-generator, and means for regulating the supply of air passing
through said chamber, substantially as described and shown.
