New or Improved Vapouriser for Petroleum Motors.
A communication by FRIEDRICH DÜRK, of Rosenthaler Strasse, Breslau, in the
Kingdom of Prussia, in the Empire of Germany, Engineer.
1, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool and 6, Bank Street,
Manchester both in the County of Lancaster and 323 High Holborn in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this inven-
tion 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 a new or improved vapouriser for petroleum-motors.
Figure 1 of the accompanying drawings shows a longitudinal section,
Figure 2 a cross section on ab of Figure 1,
Figure 3 a horizontal section on e f
Figure 4 a cross section on e d of the vapouriser, and
Figure 5 longitudinal and cross sections of the admission pipe.
The apparatus consists of a chamber G, in which a number of ribs r r r are cast
or formed, (Figure 2). A small copper tube K, having one end closed, lies across
these ribs as is seen in Figure 2. Fine incisions (see Figure 5) are made in the
tube at the points where it lies on the ribs rrr, through which, at the proper
moment, a small quantity of petroleum can escape which is quickly vapourised when
the ribs are highly heated. The tube K is in connection with a petroleum container
set at a suitable height. A return valve V (Figure 3) is fixed in the connecting
pipe in order to prevent the petroleum being forced back when the explosion in the
motor takes place. The chamber G is screwed on to the rear part of the cylinder
of the motor, and is in connection with the compression space of the cylinder by
means of openings ii. An air valve L (Figure 1) is set in the upper part of the
chamber G, which is automatically lifted during the suction period. The cross area
of the air valve can be altered as may be desired, by moving a ring piece S and the
openings o o thus made smaller or larger.
In order to set the vapouriser in action, the following particulars must be taken
note of
Spirit is poured on to the bottom of a preferably oval socket piece H (Figures 1
and 3) the flap or lid D is opened and the spirit lit. The flame heats both the
chamber G with its ribs rr and the tube Q. As soon as the tube appears to be
sufficiently heated, a small quantity of petroleumn is allowed to run in, by opening
the cock T arranged at the side (Figure 4). This petroleum vapourises at once,
the vapours passing through the intermediate piece U to the piston or plug P,
through the fine perforations of which they escape, and catch fire at the flame of
the spirit.
The petroleum vapours thus produced are intended by their combustion to bring
the heating tube X into an incandescent condition. At the same time, this flame
gives up heat to the chamber G and the vapourising tube Q, so that in this latter
the vapours for the flame can be continually renewed. The expended gases escape
through the opening B (Figures 1 and 3) which can also be provided with a
covering.
The action of the vapouriser is as follows-
When the driving piston commences its stroke, the air valve L opens auto-
matically, the inflowing air passing over the ribs rrr. The suction causes a small
quantity of petroleum to pass through the fine apertures in the tube K, this
petroleum coming on to the ribs and being immediately vapourised. The gas
produced mixes with the air providing an excellent combustible mixture.
At the

page_text: end of the piston stroke, the valve closes again and no petroleum escapes from the
tube K, either during the compression period or the expansion and blow off, as
the pressure in the cylinder is greater than in the tube K. In order to bring the
motor to a standstill, it is only necessary to close the petroleum conduit.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is-
.
A vapouriser for petroleum motors, consisting of a heating chamber suitably
provided with ribs over which a tube provided with fine incisions is laid so that
petroleum escapes through said incisions of the tube during the suction period and
is immediately vapourised on the heated ribs, the gas thus produced mixes
intimately with air which enters the chamber through an automatically acting
valve in the top of the said chamber, thus providing an excellent combustible
mixture, substantially as herein described with reference to the accompanying
drawings.
