Improvements in Gas- and Petroleum-motors.
1, EMIL KASELOWSKY of 18, Chaussee Strasse, Berlin, N. in the Kingdom of
Prussia, German Empire, 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 :-
Hitherto the ignition of gas and petrol-motors has generally been effected by means
of slide valves; but as these slide valves have a great deal of inconveniences, many
trials have been made to overcome these difficulties, but without obtaining any
satisfactory result.
My invention consists therefore in the use of an igniting tube for igniting the
explosion gases in the cylinder, because such ignition requires the least moveable
parts.
The igniting tube with the inlet device for the gases to be exploded forms the most
essential part of my invention herein after described.
In the accompanying drawing two different modifications of my improvements are
illustrated.
Figs. 1 & 2 represent a modification for the use in large motors.
Figs. 3 to 5 represent another modification for the use in small motors.
Figs. 1&2 are longitudinal sections through the cylinder of a motor.
Fig. 3 shows the same longitudinal section through the cylinder with a modified
construction of the ignition device.
Figs. 4 & 5 show two modifications of the inlet device.
Similar letters denote similar parts throughout the different figures.
The construction shown in Figs. 1 & 2 overcomes all difficulties of former
arrangements in an absolutely reliable way. I employ two inlet devices for the
explosion gases, and the igniting tube is arranged close to one of these inlet
devices, and shut up against this inlet by any suitable means as valve, slide, or
similar parts.
For the purpose of gathering the burnt residues of the igniting tube, when pressed
back by the fresh igniting current of explosion gases, I provide at the other end of
the igniting tube a hollow space of any suitable form or shape.
In the accompanying drawings c is the working cylinder, v (Fig. 1) is the inlet.
valve for the working cylinder.
The air passes in through the tube v', and the gas is sucked in through the pipe v², so
that an explosive mixture results. is a channel leading from the cylinder c to the
valve r, the latter being the inlet valve for the explosive igniting mixture. I is the
tube through which the air enters and g is the tubo through which the gas may be
let in. This valve can also be used to lead an extraordinary high explosive mixture
to the cylinder, so that the explosion of this part of the contents of the cylinder is
certainly effected when pressed'in the channel z, but it is not necessary to give such a
high degree of explosiveness to the whole working mixture. The working of the
motor is thus cheaper when fed by these two different valves.
The diameters of the air and gas inlets must be chosen so as to produce the required
explosive mixture, and may naturally be regulated at convenience by means of slides
or tubes inserted in this inlet tube. w is the valve acted by the motor in the usual
way, which opens or closes the igniting tube. d is the igniting tube made of any
suitable material, by preference of porcelain; d¹ is the empty space or reservoir
behind the igniting tube d.
It is rather evident, that the explosive mixture. entering the channel must always

certainly be filled with fresh explosive gases when the compression in the cylinder
begins.
When the compression is finished, the valve w is opened by the motor, and now the
explosive mixture contained in channel z enters the igniting tube d, pressing back
thereby the residues of the former explosion into the reservoir d'. Naturally the
ignition should be effected, when the piston has already surpassed its dead-point and
moves forward, so that the first working of the explosion is not done at or near
the dead point of the motor, but some time later, in order to increase the mechanical
effect on the piston.

It is therefore beyond all doubts, that the igniting tube itself, which is kept glowing
in the usual way, must be filled with explosive gases, and no residues contained in the
cylinder shall enter the channel and the igniting tube d. When the ignition occurs,
the explosion is communicated to the whole mixture within the channel, and the
required shot of this explosive mixture is effected within the working chamber. The
ignition of the working mixture contained in the cylinder, which mixture consists of
an explosive mixture and of the residues of the last explosion, is thus very surely and
energetically obtained.
Close
In my construction Fig. 3 only one inlet r for the explosive gases is provided,
which inlet leads them into the channel and through this into the cylinder c.
to the valve another valve wo or similar device is arranged, shutting the igniting
Lubed off from the channel. At the other end of the igniting tube d the reservoir d'
is attached, answering the same purpose as that shown in Figs. 1 & 2.
G is the gas
inlet and is the air inlet.
As will be seen from the drawing without further explanation, the only difference
between both arrangements consists in the inlet device. While the whole explosive
mixture is sucked up by the valve r only, the ignition device itself does not differ in
any way from the former modification. Fig. 4 illustrates that a slide w¹ may be used
in lieu of a valve w (Fig. 3).
Fig. 5 shows that a cock w² may be used in the same place.
Of course these improvements may be employed for gas-motors as well as for
petrol or bonzine-motors. The ignition works perfectly sure with any explosive
inaterial hitherto used with motors."
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
1. The combination of the inlet device with the inlet device leading to the
channel, and with the ignition device dd, arranged closely behind the inlet device r
and shut off from the channel by the closing device we, steered by the motor, for the
purpose as described.
