Improvements in Fluid Feeders or Regulators for Explosion Engines.
I, ALEXANDER WINTON, of 37, Bolton Place, in the City of Cleveland, County
of Cuyahoga, and State of Ohio, Mechanical Engineer, do hereby declare the
nature of this invention to be as follows:-
My invention relates to improvements in fluid feeders or regulators for explo-
sion engines, one object of which is to provide means for regulating accurately
the distance the fluid inlet or needle valve is to be opened, the same being con-
structed to permit of any desired adjustment.
Another object of my present invention pertains to the connecting of a yielding
operating member between the explosion inlet valve and the Huid regulating
valve or needle, and means for regulating the distance of the movement of the
regulating needle valve whereby it is not effected by the explosion inlet valve
irregular movement.
A further object of my present invention is the providing of a chamber through
which the gasoline is drawn on its way to the explosion inlet port, whereby it
is disintegrated and broken up into vapor and thoroughly mixed with air before
passing into the explosion end of the cylinder.
The cylinder is provided with the usual water jacket, and with an inlet at
the explosion end thereof, through which the explosive mixture is drawn. A
driving shaft is provided with a crank pin, and a piston connected therewith in
the usual manner through the medium of a pitman. An exhaust valve is provided
for the cylinder.
Extending preferably transverse the cylinder and parallel with the driving
shaft is a counter shaft carrying a cam engaging a wheel in the lower end of
the exhaust valve stem, the shaft being driven through the medium of gears,
whereby the shaft has one revolution to every two of the other shaft. The cam
is so situated and is adjustable upon its shaft through the medium of a clamping
screw that the exhaust valve is lifted at the proper time to permit the escape
of the exhaust as is well understood by those skilled in the art.
Situated preferably within the suction inlet are the electric contacts which
will be operated in any well known and desired manner and which form no part
of my present invention, and therefore need not be shown or described. These
contacts are for the purpose of igniting by an electric spark the explosive mixture.
Communicating with an air pipe is a gasoline supply pipe having a needle
valve co-acting therewith. This needle valve passes through the opposite side
of said air pipe, and through the means of a U-shaped spring is connected with
either the valve stem or the piston as may be preferred. Situated just outside
of the outer end of the needle valve is a bracket carrying an adjustable screw
or member adapted to engage the end of the valve as it is being reciprocated
and to thereby regulate the distance the valve shall be drawn from its seat, which
in turn regulates the amount of gasoline supplied at each movement of the valve.
A box or chamber has detachably serew threaded ends and this box or chamber
is filled with wire cloth. One end of this box is provided with an air pipe for

page_text: the inward passage of air and at the opposite end is a pipe communicating with
the explosion end of the end of the cylinder. The inlet is intersected by the
valve stem passing through the wall thereof and outward through a cylinder.
This last named cylinder is provided with a piston or diaphragm and a pipe
communicates with the motor cylinder at a point inside of the piston. This
pipe is connected with a pressure producing pipe preferably an air pump actuated
by the engine, and by which the pressure upon the explosion inlet valve is
regulated for the purpose of regulating the amount of explosive mixture admitted
to the cylinder and consequently the speed of the engine. A spring serves to hold
the piston normally outward.
In operation the piston we will say is at the top of its stroke and having thus
completed the exhaust. As the piston moves down within the cylinder it is
drawn through the air pipe and through the chamber containing the wire cloth
which owing to the wire cloth thoroughly breaks up the gasoline into vapor as
well as thoroughly mixing the vapor with air, and thence through the inlet port
to the explosion end of the cylinder. When the air pressure rises by reason of
the engine running faster than its normal speed, the movement of the explosion
inlet valve is less owing to the increased pressure thereon, allowing less com-
bustible mixture to pass into the cylinder until the speed of the engine is
decreased, and with the decrease of the speed of the engine the air pressure upon
the explosion inlet valve likewise decreases allowing the inlet valve to open
wider, thus automatically controlling the amount of charge and consequently
the speed of the motor.
-
The movement of the inlet port piston is at times greater than the movement
of the oil or gasoline valve and hence it is necessary to have a uniform stop or
regulator for the valve, that is to say the oil valve is regulated to move a uniform
distance irrespective of the varied movement of the stem to which it is con-
nected, the movement of the said oil valve being regulated by means of the
stop herein referred to to prevent the valve being opened out too far by the
opening of the inlet port valve as would otherwise occur. The additional move-
ment of the inlet port valve to which the needle valve is connected is permitted
through the yielding of the U-shaped spring which actuates the needle valve..
By means of this construction I am enabled to give a uniform movement of the
needle valve and thus by the simple arrangement to regulate the amount of
movement to suit the amount of air through the air pipe.
It is very essential in gasoline engines that there be a proper relative mixture
of air and gasoline, and I am enabled to accomplish this through the medium
of the adjustment hereinbefore referred to.
Improvements in Fluid Feeders or Regulators for Explosion Engines.
I, ALEXANDER WINTON, of 37, Bolton Place, in the City of Cleveland, County
of Cuyahoga and State of Ohio, United States of America, Mechanical 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: —
My invention relates to improvements in fluid feeders or regulators for explo
sion engines; and it consists in the construction, combination, and arrangement

page_text: of parts, which will be fully described hereinafter and particularly referred to
in the claims.
One object of my present invention is to provide means for regulating accu-
rately the distance the fluid inlet or needle valve is to be opened, the same being
constructed to permit of any desired adjustment.
Another object of my present invention pertains to the connecting of a yielding
operating member between the explosive inlet valve and the fluid regulating
valve or needle and means for regulating the distance of the movements of the
regulating needle or valve whereby it is not affected by the explosive inlet valve's
irregular movement.
A further object of my present invention is the providing of a chamber through
which the gasoline is drawn on its way to the explosive inlet port, whereby it
is disintegrated and broken up into vapor and thoroughly mixed with air before
passing into the explosion end of the cylinder.
I attain these objects by the mechanism illustrated in the drawings, in which
Figure 1, is a longitudinal sectional view of an engine with my invention
applied thereto.
Figure 2, is a horizontal sectional view taken on line 2-2 of Figure 1.
Figure 3, is an enlarged sectional view taken on dotted line 3-3 of Figure 2.
Referring now to the drawings, A represents a cylinder having the usual water
jacket, and B the inlet to the explosion end thereof, through which the explosive
mixture is drawn.
E is the driving shaft, F the crank pin therefor, and G.the piston rod, which
will be connected in the usual manner with the crank pin through the medium
of a pitman, not here shown.
Cis the exhaust valve, and I the piston.
Extending preferably transverse the cylinder and parallel with the driving
shaft is the counter shaft I carrying a cam K, engaging a wheel M in the lower
end of the exhaust valve stem 0, the shaft H. being driven through the medium
of the gears I and J. whereby the shaft H has one revolution to every two of the
shaft E, as is usual in explosion engines. The cam K is so situated and is
adjustable upon the shaft H, through the medium of the clamping screw L, that
the exhaust valve is lifted at the proper time to permit the escape of the exhaust,
as is well understood by those skilled in the art.
Situated preferably within the section inlet B are the electric contacts f, which
will be operated in any well known and desired manner and which form no part
of my present invention, and therefore need not be shown or described.
Communicating with the air pipe A is a gasoline supply pipe W, having a
needle valve V co-acting therewith. This needle valve, as shown, passes through
the opposite side of the pipe A' and through the means of a U-shaped spring U
is connected with either the valve stem, as here shown, or the piston S, as may
be preferred. Situated just outside of the outer end of the needle valve V is a
bracket a, carrying an adjustable screw or member b, adapted to engage the end
of the valve V as it is being reciprocated and to thereby regulate the distance
the valve shall be drawn from its seat, which in turn regulates the amount of
gasoline supplied at each movement of the valve.
A box or chamber X has detachable screw-threaded ends Z, and this box or
chamber is filled with wire cloth Y. One end of this box is provided with an air
pipe A for the inward passage of air, as indicated by arrow, and at the opposite
end with a pipe c. communicating with the explosive end Z of the engine cylinder.
This inlet is intersected by the valve 1', having a valve stem Q passing through
the wall of the inlet and outward through a cylinder T. This cylinder Tis
provided with a piston or diaphragm S, and a pipe R communicates with the
cylinder at a point inside of the piston. This pipe R is connected with a pressure
producing device, preferably an air pump, and the pressure upon the piston is
varied, according to the speed of the engine. A spring serves to hold the piston S
normally outward.

page_text: In operation we will say the piston is at the top of the stroke and having thus
completed the exhaust. As the piston moves down within the cylinder air is
drawn through the pipe A¹ and the chamber X which owing to its filling
thoroughly breaks up the gasoline into vapor, as well as thoroughly mixing the
vapor with air, and thence through the inlet port B to the explosive end of the
cylinder. When the air pressure rises by reason of the engine running faster
than its normal speed, the movement of the inlet valve is less, allowing less com-
bustible mixture to pass into the cylinder until the speed of the engine is
decreased, and with the decrease of the speed of the engine the air pressure
upon the piston D likewise decreases, allowing the inlet valve P to be opened
wider, thus automatically controlling the speed of the motor. When the piston
rises, the gases are compressed and fired at the end of the stroke, forcing the
piston down. The following stroke is the exhaust, and so the cycle of operation
goes on, as is well understood. The movement of the piston S is at times greater
than the movement of the valve V, and hence it is necessary to have a uniform
stop or regulator for the valve-that is to say, the valve P is regulated and
its movemnt varies according to the air pressure against the piston-while it is
necessary and desirable to have the valve V move a uniform distance, and hence
this is provided through the medium of the stop herein referred to, to prevent
the needle valve being opened too far by the opening of the valve P, which
would otherwise occur. The additional movement of the valve P, to which the
needle valve is connected, is permitted through the yielding spring U, which
actuates the needle valve, as clearly illustrated. By means of this construction
I am enabled to give a uniform movement of the needle valve V and yet by the
simple arrangement to regulate its amount of movement to suit the amount of
air admitted through the pipe A'.
It is very essential in gasoline engines that there be a proper relative mixture
of air and gasoline, and I am enabled to accomplish this. through the medium
of the adjustment hereinbefore referred to. The chamber X, being filled with
wire cloth Y, thoroughly breaks up the gasoline into vapor and thoroughly mixes
the vapor with the air passing therethrough into the explosion end of the cylinder,
which is found very advantageous in an engine of this character.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1st. In an explosion engine, the combination of an explosive inlet port, a valve
therefor, a variable means for regulating the distance the valve shall open and
thereby varying its movement, an air-supply, an oil supply, a valve for the oil
supply, a yielding connection between the valve, and a regulating stop for the oil
supply valve whereby the oil supply valve has a uniform movement irrespective
of the varied movements of the inlet port valve, substantially as described.
2nd. An oil and air mechanism for explosion engines comprising an inlet port
valve having a variable movement, an oil inlet valve, a spring serving as the only
means for uniting the two valves, and a regulating stop for the oil-valve whereby
the oil valve has a uniform movement irrespective of the variable movement of
the inlet port valve, substantially as described.
3rd. A fluid feeder or regulator for explosion engines, substantially as herein
shown and described.
