Fig. 1 shows a vertical sectional view of the top of an oil engine,
Fig. 2 a top view of same,
Fig. 3 a sectional view of the ejector and
Fig. 4 a side view of an auxiliary arrangement.
On the cylinder, in this case on top of the escape steam chest A, a cock B is
arranged, which opens a communication between the interior of the escape steam
chest with either the compressed air pipe a or chamber of the ejector O. The
cock on pipe b also permits of a communication between the pipe a and the
ejector C. In order to start up the engine, piston D, as shown in Fig. 1, is brought
upward and the fly wheel E (Fig. 3) is secured in that position by means of the
arrangement shown in Fig. 4, to be described below. Next cock B is turned in such
a way as to put the escape steam chest in communication with chamber of the
ejector C, then cock c is opened. The pressure air then entors pipe baud the nozzle 2
of the ejector, whereby the air is sucked out of the cylinder. In consequence of the
ensuing rarefaction, the oil valve d and the air valve e are opened. Back of the oil
valve a little mineral oil has been brought, which now enters the interior of the
gasifying chamber and there evaporates. As soon as oil vapors issue from
the ejector, cock c is to be closed and cook B is to be turned so as to permit the
pressure air coming through pipe a, to enter directly into chamber A. As soon as
the pressure air comes in contact with the oil-vapor an explosion takes place. It is
well known, that oil vapor alone or mixed with air does not explode, when brought
into contact with the heated interior of the gasifyer, but that a certain density of the
vapor is necessary to bring about the explosion. As soon as the pressure air mixes
with the oil vapor, this density is attained, the explosion ensues and the engine starts
up. It is necessary to secure the fly wheol E by means of the lover, which is
carried on the rod g. One end of the lever engages the notch in the fly wheel and
the other end is pressed upward by means of the spring i. The resistance of the
latter spring is such as to overcome the pressure of the compressed air but to give
under the pressure of the explosion. If the fly wheel were not secured, the pressure
air would drive the piston downward. The arrangement being jerked away, the rod g
swings backward around & and the arrangement does not interfero any longer with
the working of the fly wheel.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declaro that what
I claim is:
1. In an oil motor the combination of a cock B, arranged on the cylinder,
permitting a communication between the pressure air pipe a and the ejector C, a
pipe 6, being an auxiliary connecting pipe between a and for the purpose of at
first sucking the air out of the cylinder and of sucking oil vapor into it, and then

for the purpose set forth.
2. In an oil engine the combination of an auxiliary arrangement to secure the fly
wheel in a suitable position which arrangement consists of a lever f, one arm of
which engages a notch ou the periphery of the fly-wheel and whose other arm is
subjected to the pressure of a spring g, the tension of which spring is so rogulated
as to overcome the impetus of the inrushing pressure air but to give under the
pressure of the explosion, as and for the purpose set forth.
