IMPROVEMENTS IN GAS MOTOR ENGINES
Year: 1885

page_text: I, FREDERICK GEORGE MYERS of N° 27 Kerr Street Northampton, Engineer, do
hereby declare the nature of my invention for "IMPROVEMENTS IN GAS MOTOR
ENGINES" to be as follows:-
This Invention refers more particularly to that class of Gas engine, which sucks
in and mixes the necessary proportions of gas and air by means of the piston at
one end, and again expelling them through chambers, portways &c to the other end
of cylinder, where they are ignited and exploded.
After drawing in the gas and air through the necessary valves, by means of the
traverse of the piston, to one end of the cylinder, this combustable mixture is shut
in the cylinder, by the closing of the valves, being mixed and compressed by the
return traverse of the piston and force of explosion of the previous charge-The
exhaust valve, at the back of the cylinder being opened at a given point of the
piston traverse, The pent up or compressed mixture has free access to the other
side of the piston, through valves, provided in the piston for that purpose instead
of being passed through chambers, portways &c (as in present use).

page_text: I, FREDERICK GEORGE MYERS of N° 16 Princes Street (late of N° 27 Kerr
Street) Northampton Engineer do hereby declare the nature of my invention
for IMPROVEMENTS IN GAS MOTOR ENGINES and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement :-
This Invention refers more particularly to the class of gas engines, which suck
in and mix the necessary proportions of gas and air by means of the traverse of
the piston to one end of the cylinder and again expels then through the chambers,
portways &c, to the other end of the cylinder, and other side of piston, to be
ignited and exploded.
After drawing in the gas and air through the necessary valves by means of the
traverse of the piston to one end of the cylinder, this combustible mixture is
shut in the cylinder by the closing of the valves, being mixed and compressed by
the return traverse of the piston and force of explosion of the previous charge, the
exhaust at the back of the cylinder being opened and closed at given points of the
piston traverse, the pent up or compressed mixture has free access to the other side
of the piston, through the piston by means of valves provided in the said piston
for that purpose instead of being passed through chambers, portways &c, as at
present in use, being again compressed by the return stroke of the piston, and
ignited, exploded &c. in the usual course, thereby giving the required impulse to
the engine.
Refering to the accompanying Drawings A is the water jacket. B the exhaust,
C. the piston. D the piston valves. E the air inlet valve. F the gas inlet valve.
H the inlet to compressing chamber. I the exploding chamber. J the ignition
furnace. K the compression chamber. L the charge passages.
Having now particularly described and and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
The use of valves constructed or carried in the piston for the purpose of passing
the combustible mixture from one side of the piston to the other side.
