PROVISIONAL SPECIFICATION.
Improvements in Gas-motor Engines.
I, JOSEPH PICKLES BINNS, of 26 Cromwell Terrace, Halifax, in the County of York,
Engineer, do hereby declare the nature of this invention to be as follows:-
My invention has reference to gas motor engines, and my improvements consist,
Firstly, in dispensing with the inlet valve now employed in the ignition chamber
for the introduction of the explosive mixture, and in carrying out this part of my
invention I employ two cylinders arranged side by side; one of such cylinders, which
is preferably the smallest in diameter, is made with an inlet port for the introduction
of the explosive gases, whilst the other cylinder is made with an exhaust port for
allowing the spent gases to escape. One end of each of these cylinders is in com-
munication with the ignition chamber, and as the pistons of both cylinders advance at
the same time, both ports are closed simultaneously, and as the said pistons continue
to advance, the explosive mixture is compressed within the ignition chamber, and
after having reached the extent of their forward stroke, the said pistons are forced
back by the explosion of the combustible mixture, whereby both the ports previously
mentioned are opened, permitting a fresh supply of the explosive mixture to bo
introduced into the inlet port, but simultaneously therewith the products of com-
bustion escape through the exhaust port, whereupon the pistons again advance to
compress the newly admitted explosive mixture, and this goes on at every revolution
of the engine. By this means the inlet valve hitherto employed, with all its dis-
advantages, is now dispensed with, and instead thereof the inlet port above mentioned
is substituted, which is opened and closed at each forward and backward movement of'
the pistons.
Secondly. My improvements consist in providing more effective means of igniting
the explosive mixture at the proper time, and to effect this object. I form a small
passage leading out of the ignition chamber, also another small passage leading out of
the exhaust pori cylinder, which two passages I connect together with a tube, thus
making a communication from the inside of the ignition chamber to the inside of the
exhaust cylinder, the intervening connecting tube being kept in a state of incan-
descence for the purpose of igniting the explosive mixture at the proper time. I also
provide a chamber in the piston of the exhaust cylinder together with a small port
communicating with the said chamber, so that when the piston is at the end of its
stroke ready to receive the force of the explosion, the small port of the said chamber
will be opposite to the small passage in the cylinder, therefore the products of the
previous combustion remaining in the passage will be forced into the chamber of the
piston, thus the fresh charge of gases will rush through the incandescent tube,
whereby it is ignited at the proper time, and on the said piston returning to the end
of its stroke, the small port communicating with the chamber in the piston comes
opposite to the exhaust port, whereby the contents of the said chamber escape, leaving
it ready to receive the next deposit of spent gases.
I also
Thirdly. This part of my invention is intended to obtain more regular speed of the
engine, and this I accomplish in the following manner, namely, I employ a small
additional cylinder, open at one end, within which cylinder is a piston and rod caused
to reciprocate therein by an eccentric and rod in any well known manner.
employ a small bell crank lever having a hook or catch at one end, such bell crank
lever being suitably hinged to the outer end of the piston; I also employ a pin
having a large head at one end thereof, such said pin passing through the piston with
the head within the cylinder, but the opposite end of the said pin comes against the
end of the hell crank lever, so that when the air in the said cylinder is at a proper
pressure, the pin is forced against the leg of the bell crank lover, keeping such lever

page_text: out of contact with a catch on the slide of the valve, but when the pressure of air
within the cylinder is below a given or required point, which happens with the
decreased speed of the engine, the head of the pin slides backwards which prevents the
point of the pin from acting on the bell crank lever, consequently the catch at the end
thereof is caught by the catch on the slide of the valve, whereupon the slide is
operated, so as to admit an increased quantity of explosive gases, but as soon as the
engine has regained its normal speed, the pressure in the air cylinder is also regained,
causing the pin to act on the bell crank lever, whereby the slide of the valve is
released, but as soon as the speed of the engine slackens, the catch of the bell crank
lever again acts upon the slide, and this goes on so long as the speed of the engine
varies. A screw with a tapered groove enters through the side of the chamber of the
air cylinder so as to regulate the pressure therein. When the piston is drawn back
to its full extent, there is an opening in the cylinder to admit air, to prevent the
formation of a vacuum in the cylinder, after which the piston closes, and covers up
the said opening, so as to prevent the escape of air except by the small aperture
formed in the groove of the screw. In addition to this, I have a small opening in the
piston arranged to be opposite another small opening in the cylinder, to remove the
pressure after the bell crank lever has engaged with the slide catch, or after it has
passed the point that it would engage.
By the employment of this form of mechanism for regulating or governing the
slide, the ordinary hall governors and parts connected therewith are dispensed
with.

Improvements in Gas-motor Engines.
I, JOSEPH PICKLES BINNS, of 26 Cromwell Terrace. Halifax, in the County of
York, Engineer, do hereby declare the nature of this invention and in what manner
the same is to lie performed, to be particularly described and ascertained in and by
the following statement :-
My invention has reference to gas motor engines, and the first part of my improve-
ments herein consist in dispensing with the inlet valve now employed for the
introduction of the explosive mixture into the ignition chamber and in carrying out
this part of my invention I employ two cylinders arranged side by side one of such
cylinders, which is preferably the smallest in diameter is made with an inlet port for
the introduction of the explosive gases, whilst the other cylinder is made with an
exhaust port for allowing the spent gases to escape. One oud of each of these
cylinders is in communication with the ignition chamber, and as the pistons of both
cylinders advance at the same time, both ports are closed simultaneously, and as the
said pistons continue to advance, the explosive mixture is compressed within the
ignition chamber, and after having reached the extent of their forward stroke, the said
pistons are forced back by the explosion of the combustible mixture, whereby both
the ports previously mentioned are opened, permitting a fresh supply of the explosive
mixture to be introduced into the inlet port, but simultaneously therewith the products
of combustion escape through the exhaust port, whereupon the pistons again advance
to compress the newly admitted explosive mixture, and this goes on at every revolution
of the engine when with full load on or under speed.
In order that my invention may be better understood, I will now make reference
to the annexed sheet of drawings, wherein Fig. I is section of such parts of a gas
engine as are necessary to shew my invention, Fig. 2 being cross section of Fig. 1
through the line A B. The pump cylinder is shewn at C with its piston D for
supplying the explosive mixture to the ignition chamber E. My invention is shewn
at which represents a small auxiliary cylinder and piston Ġ. H reprosents the

page_text: motor piston operated by the explosions of gas in the ordinary way. a represents a
port for the inlet of explosive mixtures, and b represents an exhaust port in the motor
cylinder K for the escape of the spent gases after each explosion. 16 will therefore be
seen that when the ports are opened as shown in the drawings the piston D will force
combustible mixture through the port a into the cylinder F, and as the pistons H
and G advance, the explosive mixture is compressed within the ignition chamber E,
and by the time they reach the extent of their forward stroke, the gases are exploded
by the ignition tube I, whereby both pistons will be forced back, exposing the ports as
shewn in the drawings, when the introduction of a fresh supply of gas takes place
and the operation just described is repeated, as is well understood.
By means of the inlet port a and additional cylinder F and piston G the ordinary
inlet valve hitherto employed for admitting the explosive mixtures will be dispensed
with, and all the disadvantages appertaining to it avoided.
Secondly. My improvements consist in providing more effective means of igniting
the explosive mixture at the proper time, and to effect this object form a small
passage e leading out of the ignition chamber E, also another sinall passage d leading
out of the cylinder K, which two passages connect together with the tube L (which
may be vertical if desired) thus making an outward communication from the inside of
the ignition chamber E to the inside of the motor cylinder K the intervening
connecting tube 1 being kept in any well known manner in a state of incandescence
for the purpose of igniting the explosive mixture at the proper time.
I also provide
a chamber J in the motor piston H, together with a small porte communicating with
the said chamber, so that when the piston is at the forward end of its stroke ready to
receive the force of the explosion, the small port e of the said chamber will be opposite
to the passage d in the cylinder K, therefore the products of the previous combustion
remaining in the passage will be forced into the chamber J of the piston H thus the
fresh charge of gases will rush through the incandescent tube 1, whereby it is ignited
at the proper time and on the said piston I returning to the other end of its stroke,
the small port e communicating with the chamber J in the piston H passes opposite to
the exhaust port b, whereby the contents of the said chamber escape, leaving it ready
to receive the next deposit of spent gases.
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 :-
Firstly. In gas motor engines, the use therein of an additional cylinder and piston
such as F, and of an inlet port a in combination with the explosive or ignition
chamber, arranged and operated substantially as described and shewn herein.
Secondly. The arrangement of ports or passages c and d for forming a com-
munication through the ignition tube, in combination with the ports
chamber J for conveying away the spent gases, all as described.
