PROVISIONAL SPECIFICATION..
An Improvement in or Connected' with Gas Engines.
I RICHARD SIMON of Launder Street, Nottingham; Engineer, do hereby declare
the nature of my said invention to be as follows:-
My invention relates to a novel construction or arrangement of gas engine in which
1 form the cylinder of two diameters using a piston of two diameters therein, the
heads of the two diameters of the cylinder being connected by a pipe in its passage
through which pipe the explosive chargo is compressed to the smaller diameter end
of the cylinder.
The firing takes place in the pipe and the power resulting from that is exerted on
the smaller end of the piston effecting the out or power stroke and at the same time
a new charge of gas and air is drawn into the larger diameter of the cylinder.
Dated this 8th day of November 1888.

COMPLETE SPECIFICATION.
An Improvement in or Connected with Gas Engines.
I RICHARD SIMON of Launder Street, Nottingham, Engineer do hereby declare
the nature of my said 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 a novel construction or arrangement of gas engine in which
I form the cylinder of two diameters using a piston of two diameters therein, the
heads of the two diameters of the cylinder being connected by a pipe in its passage
through which pipe the explosion charge is compressed to the smaller diameter end
of the cylinder.
The firing takes place in the pipe and the power resulting from that is exerted on
the smaller end of the piston effecting the out or power stroke and at the same time
a new charge of gas and air is drawn into the larger diameter of the cylinder.
The annexed drawings shew the way in which I carry out the above invention.
Figure 1 is an elevation. Figures 2 and 3 vertical and Figure 4 horizontal
sections.
In the annexed drawings A is the explosion cylinder in which works the piston head B
of the double headed piston B, D. The head D thereof works in the cylinder C
(Figures 3 and 4). When the piston makes its out stroke a suitable mixture of
gas and
air is aspired through the port n and the double valve e (Figure 2). On the instroke the
valve e having been closed the contents of C are forced through the now open valve o
(Figure 2) into the pipe m (Figures 1. 2 and 4) and into the explosion cylinder A
which still contain the wasto products of the previous explosion.
By means of the pressure of the new mixture coming through m and of the piston
these are expelled through the exhaust valve r (Figures 2 and 3) the shelf or division
wall H Figures 3 and 4 in the cylinder A preventing the new mixture of gas and
air mingling with waste products. When these latter have been expelled the exhaust
valve r is closed and the completed instroke of the piston compresses the new mixture
in the pipe m and at the back of the piston head B. At the outstroke this compressed
mixture in mis ignited in any suitable manner known to engineers preferably by
tube firing as shown in the drawings and the force of the resulting explosion
impels the piston outwards a fresh charge being at the same time drawn in to C as
before described.

page_text: The return stroke is caused by the fly wheel. The valves oe and are closed by
springs and opened by suitable levers which are so contrived that the valve ris
opened a certain time before the valve o by which so called back explosions are
prevented.
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. In a gas engine in which the charge is aspired into one end of a differential
cylinder of which the end used for suction is tangibly less in capacity than the end
used for the explosion and exploded partially at the other end and partially in the tube m
the use for that purpose of a connecting pipe as shown bearing the firing arrangement
and valves e, o, for distributing the said charge substantially as described.
2. Placing in the power cylinder of a Gas Engine of the kind shown in the
annexed Drawings or a shelf or division H between the inlet of the new mixture and
the outlet of the exhaust substantially as described for the purpose of preventing the
said new mixture mingling with the effete products of combustion.
3. The general combination or arrangement substantially as described and shown,
or any mere modification thereof.
