10 fold of an internal combustion motor, without means
any additional carburetor adjustment.
Another object of this invention is to furnish
an automatically controlled valve for supply air
or vapor, the amount of vapor being increased
15 as the speed of the engine increases and reduced
as the speed of the engine is reduced, taking care
of the change in air supply necessary with the
variation in engine speed.
With the above and other objects which will
20 be apparent as the description proceeds, my in
vention consists of the following novel features
and method of construction which are illustrated
in the accompanying drawings and pointed out
in the appended claims.
In the accompanying drawings,
Fig. 1 shows the device in its entirety attached
a conventional type of internal combustion
engine, supplying the vapor from the crank case,
to illustrate the principle of the device.

matic control valve.

of the automatic control valve showing its detailed
Referring to the drawings in detail where like
40 characters of reference denote corresponding
parts, character iii indicates an internal com
bustion engine having a fan ll actuated by belt
l2 working off of the crank shaft it, there is an
automatic control valve ill supported by a con
45 ventional bracket 55, which is fastened thereto
by screws at 24, and to the engine it by means
of bolt [6, the tube ll, leading from the breather
spout IS in the crank case of the engine and a
tube l9, leading from the control valve it, to the
50 vapor inlet 28, which is placed between the car
buretor outlet 2i, and the intake manifold 22,
the control valve 14 consists of a housing 23, hav
ing holes 24 at its top for attaching bracket l5.
The front of the housing 23, has louvres 25 to
55 permit the air to enter.
There are radial slots 32 on the side of
housing 23 to act as an indicator for vane 28.
In operation the automatic control valve 14 is
mounted on the forward end of the engine imme
diately behind the fan l l, or any other convenient
location. In the drawings it is fastened at 24 to
an angular bracket 0 r support l5 bolted down 15
onto the engine with bolt it, there is a tube l7
leading from either the breather spout [8 in
the crank case of the e ngine, the radiator, or any
auxiliary air or vapor supply, this tube is led into
the control valve M terminating at a point near 0
the center of the valve I4 leading to the air or
vapor inlet 20 clamped between the ?anges of
the carburetor 2! and the intake manifold 22, the
control valve M has a vane 28 pivotally mounted
having a ?at section 29 at right angle to the vane 5
28 operating between the ends of tubes I‘! and
H9 at 2?, the ?at section 29 of the vane 28 has
an aperture or port 39, and when the air from
the fan i l is blown through the louvres 25 into
the housing 23 of the control valve M, the vane 30
28 is forced backward swinging on its pivot 3|
causing the port 36 in the ?at section 29 to reg
ister with the ends of the tubes ll’ and I9.
The operation of the pistons in the cylinders
of engine it causes a suction, drawing in the 35
gaseous fumes through the intake manifold 22,
from the carburetor 2! and in doing so also
creates a suction in the tube 19, when the port
or aperture 36 registers partially or fully with
the end of the tubes IT and 89 this suction is
further proportionately imparted to the tube ll
drawing the air or vap or to mix with the gases in
the intake manifold 22.
The entire installation of this device can be
made without any mechanical change or altera
tion in the construction of the internal combus
tion engine, whether used on automobile, aero
plane, or motorboat, a nd will automatically con
trol the amount of air or vapor drawn into the
combustion chamber through the intake mani
fold 22, depending on the velocity of the air con
tacting the vane in the control valve. It is
obvious that the fast er the engine is run the
greater the velocity 0
f air hitting the vane 28,
whether this air is produced by the fan ll op
erated by the crank shaft E3, or whether it is
produced by the speed of the automobile, aero
plane, or motorboat. The more air hitting
vane 28 in the control valve 54 the wider it
open the port 31! and the more air or vapor
be drawn into the combustion chamber of
Having thus described my invention, what I
claim and desire to secure by Letters Patent of
the United States, is:
1. A valve comprising a housing having louvres
in its front wall, a vane within said housing,
and pivotally supported from the top wall there
of, inlet and outlet ducts having opposed open
ried by said vane, and having a port therein, said
member being disposed between the open ends
of said ducts and normally closing the same, said
port in said projecting member being adapted to
register with the open ends of said ducts when
said vane is swung on its pivot support by pres
sure of air entering said perforations.
3. A valve of the class described, comprising
a housing open at its rear side and having a per
forated front wall, a movable vane disposed in
rear of and parallel to said front wall, ducts
entering said housing and having opposed open
ends disposed in closely spaced relation, and a
ported valve body carried by said vane and dis
posed between the open ends of said ducts, said 15
vane being operable by the pressure of air enter
ing the said perforations to move’ said valve
body to register the port therein with the open
ends extending into said housing, and an angu
lar projection on said vane interposed between
the open duct ends and having a port adapted to
of said ducts.
