| Abstract | The self-governing energy panel is to be used as one of a group of panels
designed to collect wind for and govern the speed of the windpowered
traveling shaft machine. This machine is designed to convert windpower
into other forms of energy (e.g. electricity or direct-drive) by
connection to a generator or other device. The panel is hung on bearings
that are on the support beams that protrude out from the horizontal shaft
of the windpowered traveling shaft machine. The panel has the majority of
its length below the bearings; however, there are several places the panel
may be attached to the beams thus changing how much of the panel is above
or below the bearings. The panel will hang vertically to the ground in
calm periods but with increasing wind speed the panel can change to a
completely horizontal position by rotating on the bearings. Weights of
various sizes may be added to the bottom of the panel, which along with
the bearing position, will control at what wind speed the panel wall reach
different angled positions. An enclosure is required around the
approximate bottom one-third of the machine. The force of the wind will
cause the panel to carry the support beam in a forward direction and turn
the main horizontal shaft of the windpowered traveling shaft machine which
will turn a generator or other device to produce electricity or mechanical
power. The size of the windpowered traveling shaft machine determines the
wind speed that it will withstand. It is a fixed-base machine. |

BACKGROUND OF THE INVENTION
This invention relates in general to all machines that generate power by
use of wind or water. In particular it relates to fixed based wind or
water powered generating machines.
Each of the self-governing energy panels is programmed by adding weights to
the hollow tubing in the bottom of the panel and by adjusting the length
of the panel's swing by a choice of bearing locations on the panel frame
itself. The panel swings freely usually remaining in a vertical position
related to the ground but can be pushed by the wind into a horizontal
position in relation to the ground. In addition, as the wind increases and
further blows the panel out from its normally lateral position torque will
be increased and the displaced panel will slow down the revolutions of the
machine around its central rotating axis compared to the number of
revolutions that could be expected if the panels remained in a strictly
vertical position. This feature enables the self-governing energy panels
on the windpowered traveling shaft machine to continue operation in higher
winds that would otherwise damage a permanently fixed vertical panel. This
displacement feature for wind and its self-governing nature are what place
this invention into a unique category for wind-powered machines. This
design also enables the machine to be built in a variety of sizes. In an
effort to show the improvements that the self-governing energy panels on
the windpowered traveling shaft machine have over other similar
inventions, the following list of U.S. patents discloses items with
features which have been conceived similarly in nature:

In Witherspoon's invention, the sails have mechanized spring stops as
compared to the panels on this invention which have no stops and are
governed by weight only. Also, there is only one bearing supporting the
turning structure. The sails hang on their end and are not controlled by
weight.
In Nagel's invention, there are no weights controlling the pyramidal cups,
and the cups are apparently regulated by an individual opening and closing
doors instead of by self-regulation.
Witherell's invention uses water instead of air to turn the axis. The
blades also stop with a mechanical stop and have no self-governing
features.
Curry's invention is designed for use in the water. His added weights are
distributed evenly throughout the lower half of the blade which while
appropriate for the water is not effective for controlling air movements.
His invention also applies power to a source rather than taking power from
the outside source.
O. E. Brown's invention has holes in its blades since they are designed for
use in water. This invention also uses mechanical stops for the blades. It
applies power to the water as opposed to taking power from the water to
provide energy.
In Houtz's invention, there are no weights controlling the speed of the
axis but a mechanically raised shield that controls the amount of wind
striking the blades. The blades are fixed to the central axis. Panels are
not used to govern this machine.
In A. E. Brown's invention, the panels have stops and are hinged at the
top. They lock in position, have no weight adjustments at the bottom of
the panels and are not self-governing.
In Erickson's invention, the blades are curved and are fixed onto the
central axis. There is no automatic provision for the controlling the rate
of revolutions except by wind speed. An operator has to manually raise a
wind shield to slow or speed up the machine for any given wind speed.
In Verplanke's invention, the blades are curved and fixed onto a central
axis. Panels are not used. There are no weights nor self-governing devices
for the machine.
On Hauhser's invention (Austria), the blades are hinged at the top but have
no weight adjustment or panel adjustment device. This machine rotates
parallel (horizontally) to the ground as opposed to rotating in a
perpendicular manner (vertical to the ground).
On the June 1980 Japanese invention, there are no hinged panels with
weights. The blades are supported on the outside of the wheel, have stops,
and are controlled by spring pressure.
On the April 1981 Japanese invention, there are no weights for the blades
which have stoppers and are returned to a normal position by spring
pressure. This machine rotates parallel (horizontally) to the ground as
opposed to rotating in a perpendicular manner (vertical to the ground).
SUMMARY OF THE INVENTION
The self-governing energy panels on the windpowered traveling shaft machine
provide a self-governing method for producing energy in low or high winds.
The wind blowing into the panel covering will turn the wheel around the
central rotating axis which will then turn other ancillary devices that
will produce electricity or similar power. In higher winds, the panels
will be displaced so that their bottoms move away from the direction from
which the wind is coming. This feature increases the torque on the machine
and helps reduce the number of revolutions per minute that the machine
turns so that the panels act as a self-governing device that keeps the
machine from spinning out of control or damaging itself in higher winds.
The tendency is for the wind to catch the panel towards the top of its
radius and carry it forward to a point where the wind panel is covered by
the wind shield. Also, since this machine can easily be built in different
sizes, the size of the machine itself can help govern its revolutions per
minute since a fifty-foot radius machine will make fewer turns in a fifty
mile-per-hour wind than would a five-foot radius machine. The wind shield
on this machine is used to shield the machine from countervailing winds
and not to control the speed of the machine.

DESCRIPTION OF THE PREFERRED EMBODIMENT
For the purposes of promoting an understanding of the principles of this
invention, reference will now be made to the embodiment illustrated in the
drawings and specific language will be used to describe the same. It will
nevertheless be understood that no limitation of the scope of the
invention is thereby intended, such alterations and further modifications
in the illustrated device, and such further applications of the principles
of the invention as illustrated therein being contemplated as would
normally occur to one skilled in the art to which this invention relates.
Referring to FIG. 1, there is a windpowered traveling shaft machine 7 which
revolves a central horizontal rotating axis 1 which when rotated will turn
other ancillary devices (not shown) which are connected to or are part of
the machine (e.g. a generator). For illustrative purposes the panels 4 are
mounted in pairs towards the end of five sets of support beams 3 radiating
out from the central rotating axis 1 of the machine. For two panels, there
must be three support beams in each set. The support beams 3 are braced by
sets of lateral beams 8 that connect the different sets of the support
beams 3. The support beams are fixed to the horizontal axis 1. Two pillars
9 in turn support the axis. Different sizes of the machine can be
constructed. A wind screen 16, approximately one-third the height of the
machine is needed to protect the machine from countervailing winds. The
wind screen should be open at the bottom to allow for smooth airflow.
Referring to FIG. 2, there is shown the central horizontal axis 1 which
rotates when the self-governing energy panels 4 are pushed by the wind.
The axis is attached to two pillow block bearings 2 located at either end
of the axis in the pillars 9. The support beams 3 are attached to the axis
1 by means of sockets 10 attached to the axis. These sockets 10 are
further supported by brackets 11 which are attached to both the socket 10
and the axis 1. As best shown in FIG. 3, the self-governing energy panel 4
is attached to the support beams 3 by inserting male connections 12 into
the female sockets 5 of the support beams. Additional support for the
support beams can be provided by the horizontal beam supports 13
permanently attached to the support beams. As can be noted in the figure,
the pillars 9 are permanently anchored in the ground. The self-governing
energy panels 4 have a panel surface 4C that can be of any type of
material that can be mounted to the panel support structure, which
consists of horizontal support frames 4A and vertical support frames 4B.
Referring again to FIG. 3, the male connections 12 can be clearly seen
inserted into the female sockets 5 which are attached to the support beam
3. These form the bearings for the panel.
In FIG. 4, the weight 6 is shown inside the bottom hollow tube horizontal
support frame 4A. The weight/s 6 are held in the bottom beam by capping
the beam with a stub shaft (plug) 14 that is either inserted into the beam
or is welded onto the beam as illustrated in FIG. 3.
FIG. 5 shows the effect of a light wind on the machine and panels with the
machine rotating in this case in a counter-clockwise direction since the
wind is coming from the right. With the weights 6 in the bottom of the
self-governing energy panel 4, the panel remains virtually perpendicular
relative to the ground as it rotates around the central axis 1.
In FIG. 6, the self-governing energy panel 4 can be seen to have moved to
other positions relative to increasing wind speed so that at some wind
speed the panel 4 will become parallel to the surface of the ground with
the weights 6 extending away from the direction of the wind.
