Improvements in or connected with Petroleum or other
Hydro-carbon Motors.
I, LOUIS STROH of Offenbach-on-the-Main in the Kingdom of Prussia in the
Empire of Germany, 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 or connected with petroleum or other
hydro-carbon motors, and its object is to provide a motor of the kind described
with improved means for supplying the liquid fuel; the said improved means being
so constructed as to entirely dispense with the use of a feed pump or automatic
valves, as hitherto employed for forcing the liquid fuel into the gas generator.
The pumps or other devices in general use for the purpose aforesaid are of very
small size, as the quantities of liquid fuel supplied at a time are extremely small;
also in consequence of the extremely small area of the passages, the latter are very
liable to become choked, and other inconveniences connected with the feeding
devices arise, necessitating frequent repairs. To overcome such difficulties,. the
device illustrated on the accompanying drawings is employed.
In these drawings :—
:
Figure 1 is a central longitudinal section of. the improved apparatus for feeding
liquid fuel, and
Figure 2 is a vertical section of the dripping device I hereinafter described.
The improved apparatus comprises a reservoir P for receiving the liquid fuel
and provided with an aperture having a hermetical screw-stopper F, a levelling
reservoir N and a dripping device I, the two reservoirs, P and N and the dripping
device I being connected to each other by pipes
The reservoir P is filled up nearly to the top through the aperture, after which
it is hermetically closed by the screw F. Compressed air is, then, forced into the
said reservoir P through the tube r, by which means the liquid fuel within the
said reservoir is forced up through the tube r¹ into the levelling reservoir N.
The amount of supply introduced into reservoir N can be regulated by means of a
screw valve R.
From the reservoir N, the petroleum is discharged through tube to the
dripping device I, the discharge end of which is regulated by a screw valve S.
The drops of petroleum which are drawn from the screw valve S by the suction of
the piston of the hydro-carbon motor are delivered through.tube into the gas
generator, and the fuel vaporised or gasified then serves to drive the motor in the
well known manner. All drops of liquid fuel which escape from the screw valve S
in the intervals of the suction strokes of the piston, and which are not delivered
into the generator, return through the tube into the upper chamber U of the
reservoir P.
The delivery of petroleum from the reservoir P into the reservoir N is slightly
in excess of the discharge from the reservoir N through the tube ³; consequently,
the excess of fluid will collect and rise within said reservoir N till it reaches the
overflow tube, through which it will run off to the upper chamber U of the
reservoir P.
The said tube is adjustable, as regards the level of its opening in the reservoir N,
by means of its stuffing-box a; by means of this arrangement, the pressure for
delivering the oil into the dripping device I may be varied and determined exactly
to correspond with the desired amount of supply.
Besides the advantage of dispensing with a pump for feeding the liquid fuel,.

page_text: this apparatus offers the special advantage that no excess of fuel is drawn into the
generator and no loss of fuel is occasioned.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a petroleum or other hydro-carbon motor, the combination, with the gas
generator, of a liquid fuel reservoir, a levelling reservoir having an overflow pipe
adjustable in height and a dripping device having an adjustable discharge, the said
two reservoirs and dripping device being connected by pipes, substantially as
described.
2. In a petroleum or other hydro-carbon motor, the combination, with the gas
generator, of a liquid fuel reservoir P, hermetically stoppered, a levelling
reservoir N, into which the liquid fuel is forced by compressed air from the said
reservoir P, a valve R to regulate the supply of liquid fuel into said reservoir N,
and a dripping device, from which the liquid fuel is drawn by the suction of the
motor piston, substantially as described.
3. In a petroleum or other hydro-carbon motor, the combination, with the gas
generator, of a liquid fuel reservoir l' hermetically stoppered, a levelling reservoir N
into which the liquid fuel is forced by compressed air from said reservoir P, a
dripping device 1 connected to said reservoir N and having an adjustable
discharge S, a discharge pipe feeding the liquid fuel drawn by the suction of
the motor piston into the gas generator, and a return tube, delivering the excess
of discharged liquid fuel back to the reservoir P, substantially as described.
