I, CHARLES EDOUARD HENRIOD, Engineer, of 23, Franche Street, Bienne, in
the Canton of Berne, and Republic of Switzerland, do hereby declare the nature
of this invention to be as follows:
This invention relates to a two stroke cycle motor working by petroleum or
gas, distinguished from all others by its simplicity, having no escapement valve,
nor pump, nor air reservoir, nor injector. By the arrangement of the explosion
chamber and the exhaust passage, there never remains so many impurities in the
cylinder as in other explosion motors; the explosion chamber is maintained warm
enough so that the motor heated beforehand may work without exterior light,
without electrical sparks and without any body whatever placed in the explosion
chamber.
The annexed drawing shows for example a motor constructed according to
this invention working by petroleum. Fig. 1 is a longitudinal section of the
whole of the motor; Fig. 2 is a plan of the same; Fig. 3 is a sectional back eleva-
tion. Figs. 4 and 5 represent details hereinafter described.
f is the frame of the motor in which the piston works. The air is com-
pressed in the chamber f by the front of the piston and the exploding mixture is
compressed in the chamber a3 by the back of the piston. The connecting-rod i
is fixed to the piston at a and to the cranked shaft at 12. kis the driving shaft.
The frame f is supported from the feet h, h. o is the water chamber. oª, 0³ are
passages for the admission and return of the water. 62 is an iron tube in which
is retained the air for each explosion. e¹ is the admission for the air drawn in by
the front of the piston a. The lift-valve d prevents the air that has been forced
into the chamber 61 by the front of the piston from passing back again. The
lift valve d also supports the suction valve e that prevents air drawn in from
the atmosphere from returning. The valves e and d are placed in a box j. The
box has two seats for valves; the valve c, which retains the air contained in
the chamber 61 and the valve 2 which closes the admission of the petroleum. The
tail of the valve is provided with a screwed head. The cylindrical part co
of this valve is provided with grooves 7 (Figs. 4 and 5). The tail e' is loose on
the rod of the valve c. Between the head and the box e³ is a spring r¹ that
presses the valve against its seat. The spring r forces the valve c on to its seat.
p is the supply tube for the petroleum admitted through the valve c³.

I, CHARLES EDOUARD HENRIOD, Engineer, of 23, Franche Street, Bienne, in
the Canton of Berne, Switzerland, 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:-
and
The present invention refers to a two stroke cycle explosion motor for gas
petroleum, in which the compression and explosion of the mixture takes place on
one side of the working piston whilst the other side of the piston serves for the
suction of the necessary quantity of air or mixture of air and gas for an explosion
through an opening and the compression thereof into an intermediate container
whence the mixture is allowed to pass through a valve into the explosion chamber.
In the drawings filed with the Provisional Specification:-
Fig. 1 is a longitudinal vertical section of an explosion motor for working with
petroleum constructed according to this invention. Figs: 2 is a plan, and Fig. 3
a cross section of the same. Figs. 4 and 5 are details of the petroleum spray
valve.
Besides the suction valve e, the pressure valve d and the valve c, which are all
automatic and can be kept partially according to their arrangement, closed by
springs the motor is provided with a spray valve with notches for the
petroleum, which is brought thereto, from the container y², by the pipe p.
This valve is also held on its seating by a spring r¹ and is forced open by a
lever with set screw g¹ which is actuated by a sleeve with cams fitting on the
regulating spindle m and movable thereon by means of a centrifugal governor.
The arrangement is such that with a light load and increasing speed of the motor
the lever is no longer actuated by the projections and the petroleum valve c²
remains closed. This controller is however not necessary for the actual speed
regulation of the motor. The spray or mixing valve c2 could also be so arranged
that it was not controlled by a special mechanism but opened by the air flowing
from the space 61 into the explosion chamber that is by the valve c, the outflow
of the petroleum would thus be regulated to correspond with the quantities of the
air flowing into the explosion chamber.
How the speed of the motor is regulated shall be shown later.
In working with gas the mixture of gas and air is drawn in through the opening e¹,
instead of air only. The valve is of course omitted and consequently also its
control mechanism. All the valves e d and c of the gas motor act automatically,
that is to say they are actuated by the mixture, i.e. by the conditions of pressure
thereof.
The pith of the invention lies in the arrangement of the suction and pressure
valves e and d and the channel ea through which the air (in working by
petroleum) or the mixture of gas and air (when working with gas) is drawn in
and forced out into the container b¹, which arrangement has for its object that the
motor automatically regulates itself without special governing mechanism, i.e. that
when running light the normal speed is not much exceeded.
As will be seen from the drawing, when the piston X is compressing the air,
the mixture is drawn into the space f through the opening e¹, suction valve e,
(which is carried on the guide rod of the valve ) and the channel e2. On the
working (explosion) stroke of the piston it is forced back through the channel e²
and through the pressure valve d into the tube b¹. Before the end of the explosion
stroke the gases of combustion escape through the opening g of the working
cylinder. At this moment the valve c opens in consequence of the difference of
pressure in front and at the back thereof and the mixture entering the explosion
